Studies not reporting GC or those not reporting actual number of GC were excluded. Twelve pertinent studies were retrieved from the PubMed database or from a manual search and considered for the meta-analysis. Pooled risk ratios and 95%CI were estimated by a random-effects model. Subgroup analysis was performed according to gender or geographical regions. Heterogeneity and publication bias were evaluated by I2and funnel plot analysis,respectively.RESULTS:DM was significantly associated with GC with a RR of 1.41(P = 0.006)(95%CI:1.10-1.81).Subgroup analyses revealed that both sexes showed a significant association with GC,with a greater magnitude of risk in females(RR = 1.90; 95%CI:1.27-2.85;P = 0.002) than in males(RR = 1.24; 95%CI:1.08-1.43;P = 0.002). In addition,the link between DM and GC was significant in East Asian DM patients(RR = 1.77;95%CI:1.38-2.26; P < 0.00001) but not in Western DM patients(RR = 1.23; 95%CI:0.90-1.68; P = 0.2).There was no evidence of publication bias,but the results indicated significant heterogeneity.CONCLUSION:This updated meta-analysis has provided evidence of positive DM-GC associations. The limited information on potentially important clinical confounding factors in each study deserves further investigation.展开更多

METHODS: We conducted a search in Pub Med, Web of Science, and the Cochrane Library covering all published papers up to July 2014. Only studies assessing survival in colorectal cancer by c-Met status were included. This meta-analysis was performed by using STATA11.0.RESULTS: Ultimately, 11 studies were included in this analysis. Meta-analysis of the hazard ratios(HR)indicated that patients with high c-Met expression have a significantly poorer overall survival(OR)(HR = 1.33, 95%CI: 1.06-1.59) and progression-free survival(PFS)(HR = 1.47, 95%CI: 1.03-1.91). Subgroup analysis showed a significant association between high c-Met expression and poorer overall survival in the hazard ratio reported(HR = 1.41, 95%CI: 1.08-1.74).CONCLUSION: The present meta-analysis indicated that high c-Met expression was associated with poor prognosis in patients with colorectal cancer.展开更多

文摘BACKGROUND Liver transplantation(LT)is recognized as an effective approach that offers survival benefits for patients with acute-on-chronic liver failure(ACLF).However,controversies remain regarding the LT selection criteria,and meta-analyses reporting overall survival outcomes across different ACLF severity grades are lacking.AIM To depict a comprehensive postoperative picture of patients with ACLF of varying severity and contribute to updating LT selection.METHODS Systematic searches in Web of Science,EMBASE,PubMed,and Cochrane databases were performed,from inception to December 26,2023,for studies exploring post-transplant outcomes among ACLF patients,stratified by severity grades as identified by the European Association for the Study of the Liver-Chronic Liver Failure criteria.The primary outcome of interest was the survival rate within one year,with post-transplant complications as secondary outcomes.Additionally,the subgroup analysis examined region-specific one-year survival rates.RESULTS A total of 17 studies involving 28025 participants were included.Patients with ACLF-1 and ACLF-2 have favorable survival within one year,with survival rates reaching 87%[95%confidence interval(CI):84%-91%]and 86%(95%CI:81%-91%),respectively.Despite the relatively lower survival(73%,95%CI:66%-80%)and higher incidence of infection(48%,95%CI:29%-67%)observed in ACLF-3 patients,their survival exceeds that of those who do not undergo LT.Moreover,post-transplant survival was highest in North America across all ACLF grades.CONCLUSION LT can provide survival advantages for ACLF patients.To optimize the utilization of scarce donor organs and improve prognosis,comprehensive preoperative health evaluations are essential,especially for ACLF-3 patients.
文摘BACKGROUND Beinaglutide,a short-acting glucagon-like polypeptide-1 receptor agonist,has shown variable efficacy in weight reduction and metabolic control in randomized controlled trials(RCTs).AIM To summarize the therapeutic effects of beinaglutide in patients with overweight/obesity with/without type 2 diabetes.METHODS RCTs involving patients receiving beinaglutide in the intervention arm and placebo or active comparator in the control arm were searched through multiple electronic databases.The change from baseline in body weight was the primary outcome;secondary outcomes included changes in body mass index(BMI),waist circumference(WC),blood pressure,glycemic parameters,lipids,and adverse events(AEs).RevMan web was used to conduct meta-analysis using random-effects models.Outcomes were presented as mean differences(MDs),odds ratios(ORs),or risk ratios(RRs)with 95%confidence intervals(95%CIs).RESULTS Six RCTs(n=800)with mostly some concerns about the risk of bias were included.Over 12-24 weeks,beinaglutide 0.1-0.2 mg thrice daily was superior to the control group in reducing total(MD=-3.25 kg,95%CI:-4.52 to-1.98,I^(2)=84%,P<0.00001)and percent(MD=-4.13%,95%CI:-4.87 to-3.39,I^(2)=54%,P<0.00001)body weight reduction.Beinaglutide also outperformed the control group in achieving weight loss by 5%(OR 4.61)and 10%(OR=5.34).The superiority of beinaglutide vs the control group was also found in reducing BMI(MD=-1.22 kg/m^(2),95%CI:-1.67 to-0.77)and WC(MD=-2.47 cm,95%CI:-3.74 to-1.19]).Beinaglutide and the control group had comparable impacts on blood pressure,glycemic parameters,insulin resistance,hepatic transaminases,and lipid profile.Beinaglutide posed higher risks of treatment discontinuation due to AEs(RR=3.15),nausea(RR=4.51),vomiting(RR=8.19),palpitation(RR=3.95),headache(RR=2.87),and dizziness(RR=6.07)than the control.However,the two groups had identical risks of total and serious AEs,diarrhea,fatigue,and hypoglycemia.CONCLUSION Short-term data from RCTs suggested that beinaglutide causes modest benefits in reducing body weight,BMI,and WC,with no significant difference in glycemic and other metabolic endpoints compared to the control arm.Safety data were consistent with those of the other drugs in the glucagon-like polypeptide-1 receptor agonist class.Larger RCTs are warranted to prove the longer-term metabolic benefits of beinaglutide.
文摘BACKGROUND This study seeks to systematically assess the effects of warm acupuncture combined with acupoint massage on the recovery of gastrointestinal function following gastric cancer surgery.AIM To evaluate the impact of warm acupuncture combined with acupoint massage on postoperative gastrointestinal function recovery after gastric cancer surgery,based on a systematic review and meta-analysis.METHODS A comprehensive search was conducted across multiple databases,including PubMed,Cochrane Library,EMBASE,Web of Science,CNKI,Wanfang,and VIP,for relevant studies published up to January 2025.Meta-analyses were carried out using RevMan 5.4,with results presented as standardized mean difference(SMD)or odds ratio with 95%confidence interval(CI).Study heterogeneity was evaluated using the I2 statistic,and sensitivity analyses were performed to assess the stability of the findings.RESULTS A total of 8 randomized controlled trials involving 694 patients were included.The meta-analysis showed that warm acupuncture combined with acupoint massage significantly improved postoperative gastrointestinal function by reducing the time to first flatus(SMD=-2.14,95%CI:-3.14 to-1.14,P<0.0001),time to first bowel movement(SMD=-2.43,95%CI:-3.52 to-1.34,P<0.0001),time to bowel sounds recovery(SMD=-3.15,95%CI:-4.50 to-1.80,P<0.00001),and time to initiate nasogastric or jejunal feeding(SMD=-1.31,95%CI:-2.44 to-0.18,P=0.02).CONCLUSION The combination of warm acupuncture and acupoint massage markedly enhances gastrointestinal recovery following surgery.

文摘Stroke remains a leading cause of death and disability worldwide,and electroacupuncture has a long history of use in stroke treatment.This meta-analysis and systematic review aimed to evaluate the efficacy of electroacupuncture and explore its potential mechanisms in animal models of ischemic stroke.The PubMed,EMBASE,Web of Science,CENTRAL,and CINAHL databases were comprehensively searched up to May 1,2024.This review included articles on preclinical investigations of the efficacy and mechanisms of electroacupuncture in treating ischemic stroke.Data from 70 eligible studies were analyzed in Stata 18.0,using a random-effects model to calculate the standardized mean difference(Hedge’s g).The risk of bias was assessed using RevMan 5.4 software,and the quality of evidence was rated according to the Grading of Recommendations,Assessment,Development,and Evaluation(GRADE)system.Subgroup analyses were conducted to test the consistency of the results and sensitivity analyses were used to assess their robustness.The quality assessment revealed that most studies adequately handled incomplete data and selective reporting.However,several methodological limitations were identified:only 4 studies demonstrated a low risk of allocation concealment,26 achieved a low risk of outcome assessment bias,and 9 had a high risk of randomization bias.Additionally,there was an unclear risk regarding participant blinding and other methodological aspects.The GRADE assessment rated 12 outcomes as moderate quality and 6 as low quality.The mechanisms of electroacupuncture treatment for ischemic stroke can be categorized as five primary pathways:(1)Electroacupuncture significantly reduced infarct volume and apoptotic cell death(P<0.01)in ischemic stroke models;(2)electroacupuncture significantly decreased the levels of pro-inflammatory factors(P<0.01)while increasing the levels of anti-inflammatory factors(P=0.02);(3)electroacupuncture reduced the levels of oxidative stress indicators(P<0.01)and enhanced the expression of antioxidant enzymes(P<0.01);(4)electroacupuncture significantly promoted nerve regeneration(P<0.01);and(5)electroacupuncture influenced blood flow remodeling(P<0.01)and angiogenesis(P<0.01).Subgroup analyses indicated that electroacupuncture was most effective in the transient middle cerebral artery occlusion model(P<0.01)and in post-middle cerebral artery occlusion intervention(P<0.01).Dispersive waves were found to outperform continuous waves with respect to neuroprotection and anti-inflammatory effects(P<0.01),while scalp acupoints demonstrated greater efficacy than body acupoints(P<0.01).The heterogeneity among the included studies was minimal,and sensitivity analyses indicated stable results.Their methodological quality was generally satisfactory.In conclusion,electroacupuncture is effective in treating cerebral ischemia by modulating cell apoptosis,oxidative stress,inflammation,stroke-induced nerve regeneration,blood flow remodeling,and angiogenesis.The efficacy of electroacupuncture may be influenced by factors such as the middle cerebral artery occlusion model,the timing of intervention onset,waveform,and acupoint selection.Despite the moderate to low quality of evidence,these findings suggest that electroacupuncture has clinical potential for improving outcomes in ischemic stroke.
文摘AIM:To investigate the association and quantify the relationship between diabetes mellitus(DM) and gastric cancer(GC) by an updated meta-analysis.METHODS:The initial PubMed search identified 1233publications. Studies not reporting GC or those not reporting actual number of GC were excluded. Twelve pertinent studies were retrieved from the PubMed database or from a manual search and considered for the meta-analysis. Pooled risk ratios and 95%CI were estimated by a random-effects model. Subgroup analysis was performed according to gender or geographical regions. Heterogeneity and publication bias were evaluated by I2and funnel plot analysis,respectively.RESULTS:DM was significantly associated with GC with a RR of 1.41(P = 0.006)(95%CI:1.10-1.81).Subgroup analyses revealed that both sexes showed a significant association with GC,with a greater magnitude of risk in females(RR = 1.90; 95%CI:1.27-2.85;P = 0.002) than in males(RR = 1.24; 95%CI:1.08-1.43;P = 0.002). In addition,the link between DM and GC was significant in East Asian DM patients(RR = 1.77;95%CI:1.38-2.26; P < 0.00001) but not in Western DM patients(RR = 1.23; 95%CI:0.90-1.68; P = 0.2).There was no evidence of publication bias,but the results indicated significant heterogeneity.CONCLUSION:This updated meta-analysis has provided evidence of positive DM-GC associations. The limited information on potentially important clinical confounding factors in each study deserves further investigation.
文摘AIM:To conduct a meta-analysis comparing outcomes after pancreaticoduodenectomy(PD)with or without prophylactic drainage.METHODS:Relevant comparative randomized and nonrandomized studies were systemically searched based on specific inclusion and exclusion criteria.Postoperative outcomes were compared between patients with and those without routine drainage.Pooled odds ratios(OR)with 95%CI were calculated using either fixed effects or random effects models.RESULTS:One randomized controlled trial and four non-randomized comparative studies recruiting 1728patients were analyzed.Patients without prophylactic drainage after PD had significantly higher mortality(OR=2.32,95%CI:1.11-4.85;P=0.02),despite the fact that they were associated with fewer overall complications(OR=0.62,95%CI:0.48-0.82;P=0.00),major complications(OR=0.75,95%CI:0.60-0.93;P=0.01)and readmissions(OR=0.77,95%CI:0.60-0.98;P=0.04).There were no significant differences in the rates of pancreatic fistula,intraabdominal abscesses,postpancreatectomy hemorrhage,biliary fistula,delayed gastric emptying,reoperation or radiologic-guided drains between the two groups.CONCLUSION:Indiscriminate abandonment of intraabdominal drainage following PD is associated with greater mortality,but lower complication rates.Future randomized trials should compare routine vs selective drainage.
文摘AIM: To assess the prognostic value of c-Met status in colorectal cancer. METHODS: We conducted a search in Pub Med, Web of Science, and the Cochrane Library covering all published papers up to July 2014. Only studies assessing survival in colorectal cancer by c-Met status were included. This meta-analysis was performed by using STATA11.0.RESULTS: Ultimately, 11 studies were included in this analysis. Meta-analysis of the hazard ratios(HR)indicated that patients with high c-Met expression have a significantly poorer overall survival(OR)(HR = 1.33, 95%CI: 1.06-1.59) and progression-free survival(PFS)(HR = 1.47, 95%CI: 1.03-1.91). Subgroup analysis showed a significant association between high c-Met expression and poorer overall survival in the hazard ratio reported(HR = 1.41, 95%CI: 1.08-1.74).CONCLUSION: The present meta-analysis indicated that high c-Met expression was associated with poor prognosis in patients with colorectal cancer.
文摘BACKGROUND A few randomized clinical trials(RCT)and their meta-analyses have found patent foramen ovale closure(PFOC)to be beneficial in prevention of stroke compared to medical therapy.Whether the benefit is extended across all groups of patients remains unclear.AIM To evaluate the efficacy and safety of PFOC vs medical therapy in different groups of patients presenting with stroke,we performed this meta-analysis of RCTs.METHODS Electronic search of PubMed,EMBASE,Cochrane Central,CINAHL and ProQuest Central and manual search were performed from inception through September 2018 for RCTs.Ischemic stroke(IS),transient ischemic attack(TIA),a composite of IS,TIA and systemic embolism(SE),mortality,major bleeding,atrial fibrillation(AF)and procedural complications were the major outcomes.Random-effects model was used to perform analyses.RESULTS Meta-analysis of 6 RCTs including 3560 patients showed that the PFOC,compared to medical therapy reduced the risk of IS[odds ratio:0.34;95%confidence interval:0.15-0.78;P=0.01]and the composite of IS,TIA and SE[0.55(0.32-0.93);P=0.02]and increased the AF risk[4.79(2.35-9.77);P<0.0001].No statistical difference was observed in the risk of TIA[0.86(0.54-1.38);P=0.54],mortality[0.74(0.28-1.93);P=0.53]and major bleeding[0.81(0.42-1.56);P=0.53]between two strategies.Subgroup analyses showed that compared to medical therapy,PFOC reduced the risk of stroke in persons who were males,≤45 years of age and had large shunt or atrial septal aneurysm.CONCLUSION In certain groups of patients presenting with stroke,PFOC is beneficial in preventing future stroke compared to medical therapy.

文摘AIM:To investigate whether an association exists between sleep-associated movement disorders and cardiovascular disease(CVD).METHODS:Several studies have observed the relationship of sleep-associated movement disorders such as restless legs syndrome(RLS)and periodic limb movements during sleep with CVD,but the results were still contradictory.We performed an extensive literature search on Pub Med,Medline and Web of Science published from inception to December 2014.Additional studies were manually searched from bibliographies of retrieved studies.Meta-analyses were conducted with Stata version 12.0(Stata Corp,College Station,Texas).Pooled odds ratios(ORs)and 95%CIs were calculated to assess the strength of association using the random effects model.Sensitivity and subgroup analyses were performed to explore the underlying sources of heterogeneity.The publication bias was detected using Egger’s test and Begg’s test.RESULTS:A total of 781 unique citations were indentified from electronic databases and 13 articles in English were finally selected.Among these studies,nine are cohort studies;two are case-control studies;and two are cross-sectional studies.The results showed that the summary OR of CVD associated with sleepassociated movement was 1.51(95%CI:1.29-1.77)in a random-effects model.There was significant heterogeneity between individual studies(P for heterogeneity=0.005,I2=57.6%).Further analysis revealed that a large-scale cohort study may account for this heterogeneity.A significant association was also found between RLS and CVD(OR=1.54,95%CI:1.24-1.92).In a fixed-effects model,we determined a significant relationship between sleep-associatedmovement disorders and coronary artery disease(CAD)(OR=1.34,95%CI:1.16-1.54;P for heterogeneity=0.210;I2=30.0%).Our meta-analysis suggests that sleep-associated movement disorders are associated with prevalence of CVD and CAD.CONCLUSION:This finding indicates that sleep-associated movement disorders may prove to be predictive of underlying CVD.
