A Meta-analysis for Major Complications Between Traditional Pacemaker and Leadless Pacemaker

Abstract Objectives To compare the major complications between leadless pacemaker (LP) and traditional pacemakers(TP).Background The TP shows some advantages in avoiding pocket- and lead-related complications over the TP and is increasingly used in clinical practice. However, the clinical effect of LP remains controversial.Methods PUBMED、EMBASE、The COCHRANE LIBRARY、CNKI and WANGFANG databases were searched from July 2013 to August 2018. Data concerning the study’s design, patients’ characteristics and outcomes were extracted. The primary end-point is the major complications. The second end-points are elevated pacing threshold, cardiac perforation/effusion, device dislodgement and vascular events.Results A total of 6 studies fulfilled the inclusion criteria. Only 4 of which can provide the data of major complications. The main complications of LP were statistically significantly decreased compared with that of TP(OR 0.41,95%CI:0.29-0.56,P<0.00001,I2=42%).We extracted the data of elevated pacing threshold, cardiac perforation/effusion, device dislodgement and vascular events in 4 other of these 6 studies. There was no significant difference in elevated pacing threshold (OR 0.95, 95%CI:0.24-3.70,P=0.94, I2=31%), cardiac perforation/effusion(OR 1.78,95%CI:0.33-9.58, P=0.50,I2=87%), vascular events (OR1.58, 95%CI:0.45-5.53, P=0.47,I2=47%) and device dislodgement(OR 0.22,95%CI:0.01-5.69,P=0.36,I2=81%) between LP and TP.Conclusion Compared with TP, LP showed a significantly decreased risk in major complications. This indicates that LP has a good prospect to be applicated in clinical practice.

Abstract Background The clinical benefits of treatment with radiofrequency ablation (RFA) and repeat hepatic resection (RHR) for recurrent hepatocellular carcinoma (RHCC) remain controversial. This meta-analysis aims to evaluate the outcomes and major complications of RFA versus RHR in patients with early-stage RHCC. Methods PubMed, Embase, Web of Science and the Cochrane Library were systematically searched for comparative studies on the evaluation of RHR versus RFA for RHCC. The primary outcome was overall survival (OS), and the secondary outcomes were progression-free survival (PFS) and major complications. Meta-analysis was performed using a random-effects model or fixed-effects model, and heterogeneity was tested by the Cochran Q statistic. Results Ten studies with 1612 patients (RHR = 654, RFA = 958) were included in the meta-analysis. The meta-analysis showed that RHR had superior OS (HR 0.77, 95% CI =0.65–0.92, P = 0.004) and PFS (HR 0.81, 95% CI =0.67–0.98, P = 0.027) compared to RFA, whereas major complications may be less frequent in the RFA group (OR 0.15, 95% CI = 0.06–0.39, P < 0.001). In the subgroup analysis of patients with single RHCC ≤3 cm, OS (HR 1.03, 95% CI =0.69–1.52, P = 0.897) and PFS (HR 0.99, 95% CI = 0.71–1.37, P = 0.929) showed no significant differences in the comparison of RHR and RFA. In single RHCC> 3 cm and ≤ 5 cm, RFA showed an increased mortality in terms of OS (HR 0.57, 95% CI = 0.37–0.89, P = 0.014). Conclusion RHR offers a longer OS and PFS than RFA for patients with RHCC, but no statistically significant difference was observed for single RHCC ≤3 cm. The advantages of fewer major complications may render RFA an alternative treatment option for selected patients.

Clinical Relevance The use of laser light during bleaching will not reduce the incidence or severity of sensitivity and will not increase the degree of color change compared with nonlaser light sources. SUMMARY Objective: To evaluate whether the use of laser during in-office bleaching promotes a reduction in dental sensitivity after bleaching compared with other light sources. Methods: The present review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and is registered with PROSPERO (CDR42018096591). Searches were conducted in the PubMed/Medline, Web of Science, and Cochrane Library databases for relevant articles published up to August 2018. Only randomized clinical trials among adults that compared the use of laser during in-office whitening and other light sources were considered eligible. Results: After analysis of the texts retrieved during the database search, six articles met the eligibility criteria and were selected for the present review. For the outcome dental sensitivity, no significant difference was found favoring any type of light either for intensity (mean difference [MD]: −1.60; confidence interval [CI]: −3.42 to 0.22; p=0.09) or incidence (MD: 1.00; CI: 0.755 to 1.33; p=1.00). Regarding change in tooth color, no significant differences were found between the use of the laser and other light sources (MD: −2.22; CI: −6.36 to 1.93; p=0.29). Conclusions: Within the limitations of the present study, laser exerts no influence on tooth sensitivity compared with other light sources when used during in-office bleaching. The included studies demonstrated that laser use during in-office bleaching may have no influence on tooth color change.

Background: β-amyloid (Aβ) accumulates abnormally to senile plaque which is the initiator of Alzheimer's disease (AD). As one of the Aβ-degrading enzymes, Insulin-degrading enzyme (IDE) remains controversial for its protein level and activity in Alzheimer's brain. Methods: The electronic databases PubMed, EMBASE, The Cochrane Library, OVID and Sinomed were systemically searched up to Sep. 20th, 2017. And the published case-control or cohort studies were retrieved to perform the meta-analysis. Results: Seven studies for IDE protein level (AD cases = 293; controls = 126), three for mRNA level (AD cases = 138; controls = 81), and three for enzyme activity (AD cases = 123; controls = 75) were pooling together. The IDE protein level was significantly lower in AD cases than in controls (SMD = - 0.47, 95% CI [-0.69, -0.24], p < 0.001), but IDE mRNA and enzyme activity had no significant difference (SMD = 0.02, 95% CI [-0.40, 0.43] and SMD = 0.06, 95% CI [-0.41, 0.53] respectively). Subgroup analyses found that IDE protein level was decreased in both cortex and hippocampus of AD cases (SMD = -0.43, 95% CI [-0.71, -0.16], p = 0.002 and SMD = -0.53, 95% CI [-0.91, -0.15], p = 0.006 respectively). However, IDE mRNA was higher in cortex of AD cases (SMD = 0.71, 95% CI [0.14, 1.29], p = 0.01), not in hippocampus (SMD = -0.26, 95% CI [-0.58, 0.06]). Conclusions: Our results indicate that AD patients may have lower IDE protease level. Further relevant studies are still needed to verify whether IDE is one of the factors affecting Aβ abnormal accumulation and throw new insights for AD detection or therapy.

Abstract Background For patients with hepatocellular carcinoma (HCC) with microvascular invasion (MVI) after curative resection, the effects of various postoperative adjuvant therapies are not summarized in detail, and the comparison between the effects of various adjuvant therapies is still unclear. Thus, we collected existing studies on postoperative adjuvant therapies for patients with HCC with MVI after curative resection and analyzed the effects of various adjuvant therapies. Method We collected all studies on postoperative adjuvant therapy for patients with HCC with MVI after curative resection from PubMed, EMBASE, Cochrane Library and SinoMed ending on May 1, 2019. Overall survival (OS) and disease-free/recurrence-free survival (RFS) between each group were compared in these studies by calculating the pooled hazard ratio (HR) and 95% confidence interval (CI). All statistical analyses were assessed by two authors independently. Result A total of 13 studies were included in this study, including 824 postoperative adjuvant transarterial chemoembolization (pa-TACE) patients, 90 postoperative radiotherapy patients, 57 radiofrequency ablation (RFA)/re-resection patients, 16 sorafenib patients and 886 postoperative conservative treatment patients. The results showed that pa-TACE significantly improved OS and RFS compared with postoperative conservative treatment in patients with HCC with MVI after curative resection (HR: 0.64, 95% CI: 0.55–0.74, p < 0.001; HR: 0.70, 95% CI: 0.62–0.78, p < 0.001, respectively). There was no significant difference in OS between pa-TACE and radiotherapy in patients with HCC with MVI (HR: 1.75, 95% CI: 0.92–3.32, p = 0.087). RFS in patients with HCC with MVI after pa-TACE was worse than that after postoperative adjuvant radiotherapy (HR: 2.29, 95% CI: 1.43–3.65, p < 0.001). The prognosis of pa-TACE and RFA/re-resection in patients with MVI with recurrent HCC had no significant differences (HR: 0.65, 95% CI: 0.09–4.89, p = 0.671). Adjuvant treatments significantly improved the OS and RFS of patients compared with the postoperative conservative group (HR: 0.580, 95% CI: 0.480–0.710, p < 0.001; HR: 0.630, 95% CI: 0.540–0.740, p < 0.001, respectively). Conclusion Compared with postoperative conservative treatment, pa-TACE, postoperative radiotherapy and sorafenib can improve the prognosis of patients with hepatocellular carcinoma with microvascular invasion after curative resection. Postoperative radiotherapy can reduce the recurrence of patients with HCC with MVI after curative resection compared with pa-TACE.

Objective To explore the impact of appendectomy history on emergence of Parkinson’s disease (PD). Background Although there are several studies to investigate the relationship between appendectomy history and emergence of PD, the results are still controversial. Methods We performed a comprehensive electronic search of the literature (the Cochrane Library, PubMed, and the Web of Science) up to April 2020 to identify studies that had employed databases allowing comparison of emergence of PD between patients with and those without appendectomy history. To integrate the impact of appendectomy history on emergence of PD, a meta-analysis was performed using random-effects models to calculate the risk ratio (RR) and 95% confidence interval (CI) for the selected studies, and heterogeneity was analyzed using I2 statistics. Results Four studies involving a total of 6 080 710 patients were included in this meta-analysis. Among 1 470 613 patients with appendectomy history, 1845 (.13%) had emergences of PD during the observation period, whereas among 4 610 097 patients without appendectomy history, 6743 (.15%) had emergences of PD during the observation period. These results revealed that patients with appendectomy history and without appendectomy had almost the same emergence of PD (RR, 1.02; 95% CI, .87-1.20; P = .83; I2 = 87%). Conclusion This meta-analysis has demonstrated that there was no significant difference in emergence of PD between patients with and those without appendectomy history.

Background There is an ongoing debate on the off-hour effect on endovascular treatment (EVT) for acute large vessel occlusion (LVO). Aims This meta-analysis aimed to compare time metrics and clinical outcomes of acute LVO patients who presented/were treated during off-hour with those during working hours. Summary of review Structured searches on the PubMed, Embase, Web of Science, and Cochrane Library databases were conducted through February 23rd, 2021. The primary outcomes were onset to door, door to imaging, door to puncture, puncture to recanalization, procedural time, successful recanalization, symptomatic intracerebral hemorrhage (SICH), mortality in hospital, good prognosis (90-day modified Rankin Scale [mRS] score 0-2), and 90-day mortality. The secondary outcomes were imaging to puncture, onset to puncture, onset to recanalization, door to recanalization time, mRS 0-2 at discharge, and consecutive 90-day mRS score. The odds ratio (OR) and weighted mean difference (WMD) with 95% confidence interval (CI) of the outcomes were calculated using random-effect models. Heterogenicity and publication bias were analyzed. Subgroup and sensitivity analyses were conducted as appropriate. Nineteen studies published between 2014 and 2021 with a total of 14185 patients were eligible for quantitative synthesis. Patients in the off-hour group were significantly younger than those in the on-hour group and with comparable stroke severity and intravenous thrombolysis rate. The off-hour group had longer onset to door (WMD [95%CI], 12.83 [1.84-23.82] min), door to puncture (WMD [95%CI], 11.45 [5.93-16.97] min), imaging to puncture (WMD [95%CI], 10.39 [4.61-16.17] min), onset to puncture (WMD [95%CI], 25.30 [13.11-37.50] min), onset to recanalization (WMD [95%CI], 25.16 [10.28-40.04] min), and door to recanalization (WMD [95%CI], 18.02 [10.01-26.03] min) time. Significantly lower successful recanalization rate (OR [95%CI], 0.85 [0.76-0.95]; P=0.004; I2=0%) was detected in the off-hour group. No significant difference was noted regarding SICH and prognosis. But a trend towards lower OR of good prognosis was witnessed in the off-hour group (OR [95%CI], 0.92 [0.84-1.01]; P=0.084; I2=0%). Conclusions Patients who presented/were treated during off-hour were associated with excessive delays before the initiation of EVT, lower successful reperfusion rate, and a trend towards worse prognosis when compared with working hours. Optimizing the workflows of EVT during off-hour is needed.

There is limited evidence on the standard care for painful obstructive chronic pancreatitis (CP), while comparisons of endoscopic and surgical modes for pain relief have yielded conflicting results from small sample sizes. We aimed to obtain a clear picture of the matter by a meta-analysis of these results. We searched the Pubmed, Embase, and Cochrane Library databases to identify studies comparing endoscopic and surgical treatments for painful obstructive CP. Pooled effects were calculated by the random effect model. Primary outcomes were overall pain relief (complete and partial), and secondary outcomes were complete and partial pain relief, complication rate, hospitalization duration, and endocrine insufficiency. Seven studies with 570 patients were included in the final analysis. Surgical drainage was associated with superior overall pain relief [OR 0.33, 95% CI 0.23–0.47, p < 0.001, I2 = 4%] and lesser incidence of endocrine insufficiency [OR 2.10, 95% CI 1.20–3.67, p = 0.01, I2 = 0%], but no significant difference in the subgroup of complete [OR 0.57, 95% CI 0.32–1.01, p = 0.054, I2 = 0%] or partial [OR 0.67, 95% CI 0.37–1.22, p = 0.19, I2 = 0%] pain relief, complication rates [OR 1.00, 95% CI 0.41–2.46, p = 0.99, I2 = 49%], and hospital stay [OR −0.54, 95% CI −1.23–0.15, p = 0.13, I2 = 87%] was found. Surgery is associated with significantly better overall pain relief and lesser endocrine insufficiency in patients with painful obstructive CP. However, considering the invasiveness of surgery, no significant differences in complete or partial pain relief, and heterogeneity of a few parameters between two groups, endoscopic drainage may be firstly performed and surgical drainage may be considered when endoscopic drainage fails.

Introduction : Direct transfer to angiography suite (DTAS) for patients with suspected large vessel occlusion strokes potentially requiring mechanical thrombectomy has been shown to shorten treatment times and improve outcomes compared to conventional imaging (CI) selection. This meta‐analysis compares both approaches to build more concrete evidence. Methods : The potentially relevant studies that were published in four electronic databases/search engines (PubMed, Web of Science, Cochrane Library, and Scopus) till August 2021 were reviewed. Eligible studies were included if they enrolled >10 patients in both groups, were published in English and reported baseline and procedural characteristics and 90‐day outcomes. Relevant data were then extracted and analyzed. Results : Among 4514 searched studies, six qualified for the analysis. Time from door to puncture (MD = ‐26.76minutes, 95 % CI [‐39.48, ‐14.03], P< 0.0001) as well as door to reperfusion (MD = ‐27.21 minutes,95% CI [‐47.42, ‐7.01], P = 0.008) were significantly shorter and the rates of functional independence(mRS0‐2: RR = 1.28, 95% CI [1.03, 1.60], P = 0.03) at 90‐days were significantly higher in the DTAS versus the CI approach. There was no statistically significant difference between DTAS and CI groups in terms of successful reperfusion (modified Thrombolysis In Cerebral Infraction [mTICI] score2B‐3: RR = 0.99, 95% CI [0.93, 1.06], P = 0.86), near complete/ full reperfusion (mTICI 2C‐3: RR = 0.84,95% CI [0.68, 1.04], P = 0.11), or fair outcomes at 90‐days (mRS 0–3: RR = 1.05, 95% CI [0.67, 1.64],P = 0.84). Moreover, there was no difference between groups regarding symptomatic intracranial hemorrhage (RR = 0.81, 95% CI [0.55, 1.17], P = 0.26) or 90 day‐mortality (RR = 0.85, 95% CI [0.59, 1.24],P = 0.41). Conclusions : Our meta‐analysis showed that DTAS significantly improves time metrics and functional outcome with comparable safety to the CI approach. Multicenter randomized clinical trials are ongoing to confirm these results.

Background. A substantial proportion of patients undergoing colorectal surgery receive a temporary stoma, and the timing for stoma closure remains unclear. The aim of this study was to evaluate the safety and feasibility of early stoma closure (ESC) compared with routine stoma closure (RSC) after colorectal surgery. Methods. We comprehensively searched PubMed, Embase, and the Cochrane Library for randomized controlled trials that compared ESC and RSC after colorectal surgery. Results. A total of 7 randomized controlled trials with 814 enrolled patients were identified for this meta-analysis. There were no significant differences between the ESC and RSC groups regarding the complications of stoma closure (26.8% and 16.6%, respectively; odds ratio [OR]: 1.30; 95% confidence interval [CI]: 0.89-1.90; P = .17). A subgroup analysis was conducted by Clavien-Dindo grade of complication, and no significant difference was observed in any subgroup ( P > .05). However, the ESC group had a significantly higher risk of wound complications than the RSC group (17.6% and 7.8%, respectively; OR: 2.61; 95% CI: 1.43-4.76; P = .002), and the RSC group had more cases of small bowel obstruction than the ESC group (3.1% and 8.4%, respectively; OR: 0.37; 95% CI: 0.15-0.87; P = .02). Conclusions. ESC is a safe and effective therapeutic approach in patients who have undergone colorectal surgery; it is associated with a reduced risk of bowel obstruction but a higher risk of wound complications.
