Cancer Event Rate and Mortality with Thienopyridines: A Systematic Review and Meta-Analysis

Introduction: Hybrid convergent epicardial/endocardial ablation was developed in response to the limited effectiveness of endocardial catheter ablation for persistent (PersAF) and longstanding PersAF (LSPAF). The objective of this study was to perform a systematic review and meta-analysis of reported safety and efficacy outcomes with convergent procedures. Methods: Predefined search terms were used in PubMed; the initial search was performed in June 2019 and updated in May 2020. Abstracts and full text in English were reviewed for peer-reviewed, primary clinical studies of hybrid convergent procedures in PersAF/LSPAF. Meta-analysis was performed with using a random effects model with a restricted maximum likelihood estimator and forest plots. Heterogeneity was tested using Cochran’s Q-test. Results: The updated search yielded 325 unique results. Two articles from meta-analyses were added. Nineteen articles met inclusion with safety and/or efficacy data. Three overlapping studies were excluded. Results from the randomized CONVERGE trial were added, for a total of 1084 patients in 17 studies; 94% had PersAF or LSPAF. The 30-day major adverse event rate was 3.1% (95% CI 1.9% - 4.3%; n=1084; 17 studies), excluding pericardial effusions (PE) (non-emergent inflammatory response) and 5.1% (95% CI 3.6% - 6.6%) overall. The PEs may be mitigated by anti-inflammatory prophylaxis, pericardial drainage and appropriate patient monitoring. Freedom from AF/atrial arrhythmia at one year or later was 75.0% (95% CI 66.0%-83.9%; n=805; 14 studies) regardless of anti-arrhythmic drugs (AAD) and 64.9% (95% CI 54.7%-75.1%; n=494; 8 studies) off AADs/ absent increased dosage of failed AADs. Heterogeneity across studies was detected for effectiveness (p<0.0001), but not for safety (p=0.12). Conclusions: This meta-analysis shows high efficacy of hybrid convergent ablation at one year, even off AADs, and a reasonable safety in mostly persistent or long-standing persistent AF.

Background The optimal first line treatment for patients with isolated superficial venous thrombosis (SVT) of the lower extremity is unknown. Objective This article reports estimates of the rate of venous thromboembolic complications among patients with SVT according to treatment. Materials and Methods A systematic review and meta-analysis was performed using unrestricted searches of electronic databases. Reported events were transformed to event per 100 patient-years of follow-up and a random effects model was used to calculate pooled rates according to pre-specified treatment categories. The primary outcome was the occurrence of deep vein thrombosis (DVT) or pulmonary embolism (PE) during the study follow-up period. Results Seventeen articles, including 6,862 patients, were included in the meta-analysis. Fondaparinux had the lowest event rate with 1.4 events per 100 patient-years of follow-up (95% confidence interval [CI], 0.5–2.8, I 2 = 18%). Pooled event rates for DVT or PE ranged from 9.3 to 16.6 events per 100 patient-years across other treatment categories, and the pooled event rate for no treatment/placebo was 10.5 events per 100 patient-years (95% CI, 3.0–22.0). Major bleeding was low and similar across all treatment categories. Heterogeneity was moderate to high for most pooled estimates. Conclusion While pooled event rates suggest that fondaparinux achieves the lowest rate of DVT or PE, low-quality evidence for other treatments prevents firm conclusions about the optimal treatment for SVT.

OBJECTIVEPatients with poor-grade aneurysmal subarachnoid hemorrhage (aSAH) (World Federation of Neurosurgical Societies Grade IV or V) are often considered for decompressive craniectomy (DC) as a rescue therapy for refractory intracranial hypertension. The authors performed a systematic review and meta-analysis to assess the impact of DC on functional outcome and death in patients after poor-grade aSAH.METHODSA systematic review and meta-analysis were performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Articles were identified through the Ovid Medline, Embase, Web of Science, and Cochrane Library databases from inception to October 2015. Only studies dedicated to patients with poor-grade aSAH were included. Primary outcomes were death and functional outcome assessed at any time period. Patients were grouped as having a favorable outcome (modified Rankin Scale [mRS] Scores 1–3, Glasgow Outcome Scale [GOS] Scores 4 and 5, extended Glasgow Outcome Scale [GOSE] Scores 5–8) or unfavorable outcome (mRS Scores 4–6, GOS Scores 1–3, GOSE Scores 1–4). Pooled estimates of event rates and odds ratios with 95% confidence intervals were calculated using the random-effects model.RESULTSFifteen studies encompassing 407 patients were included in the meta-analysis (all observational cohorts). The pooled event rate for poor outcome across all studies was 61.2% (95% CI 52%–69%) and for death was 27.8% (95% CI 21%–35%) at a median of 12 months after aSAH. Primary (or early) DC resulted in a lower overall event rate for unfavorable outcome than secondary (or delayed) DC (47.5% [95% CI 31%–64%] vs 74.4% [95% CI 43%–91%], respectively). Among studies with comparison groups, there was a trend toward a reduced mortality rate 1–3 months after discharge among patients who did not undergo DC (OR 0.58 [95% CI 0.27–1.25]; p = 0.168). However, this trend was not sustained at the 1-year follow-up (OR 1.09 [95% CI 0.55–2.13]; p = 0.79).CONCLUSIONSResults of this study summarize the best evidence available in the literature for DC in patients with poor-grade aSAH. DC is associated with high rates of unfavorable outcome and death. Because of the lack of robust control groups in a majority of the studies, the effect of DC on functional outcomes versus that of other interventions for refractory intracranial hypertension is still unknown. A randomized trial is needed.

Abstract Introduction: Transplant patients are a vulnerable group due to their immunocompromised status. Understanding how COVID-19 can present in this group is clinically important. Therefore, we conduct a systematic review and meta-analysis on clinical features and management of transplant patients with COVID-19.Methods: Five databases were searched in May 2020 to include all relevant studies reporting clinical features or outcomes of COVID-19 infection in transplant patients. Data on clinical presentation, outcomes, lab values, imaging, and drug regimen were extracted. CMA software was used for meta-analysis. Protocol was registered in PROSPERO (CRD42020189458).Results: A total of 49 studies were finally included for analysis. Patients mainly complained from fever with event rate 74.40 % (95% CI= 69.4-78.8), cough 61.10% (95% CI= 55.8-66), and dyspnea 46.60% (95% CI= 69.4-78.8). Blood urea nitrogen 78.90% (95% CI= 54.7-92), ESR 78.10% (95% CI=52.3-92.1), and D-dimer 74.10% (95 % CI= 53-87.9) were the most elevated observed laboratory values. Ground glass opacities (GGO) were observed with event rate 68.10% (95% CI= 20.4-94.9). For treatment, immunosuppressants were used in 88.80% (95% CI= 77.6-94.8) of patients, followed by antibiotics and antiviral drugs 68.40% (95% CI= 52.4-80.9), 66.80% (95% CI = 45-83.2), respectively. Mechanical ventilation was used in 26.30% (95% CI=21-32.4) patients while 33.7% (95% CI= 20.7-49.9) intubated. Rejection occurred in 11% (95% CI= 4.4-25) of the patients. Finally, 18.20% (95% CI= 12.6-25.7) died. Conclusion: Clinical characteristics and management in transplant COVID patients suggest the similar course in non-transplant. Fever, cough, dyspnoea, elevated blood urea nitrogen level, elevated CRP, elevated d-dimer, GGO, and consolidation were found to be the most frequent abnormalities. No direct, comparative analysis with non-transplant COVID population limited our results; however, numerous studies that examined the infected general population found similar, less augmented findings. Most of the included sample were kidney transplant patients; therefore, more studies are needed to address other types of COVID-19 infected transplant patients.

Introduction: The incidence of acute myocardial injury (AMI) among Coronavirus Disease 19 (COVID-19)-infected patients remain unclear. We aimed to conduct a systematic review and meta-analysis to further explore the incidence AMI in these patients. Methods: We comprehensively searched the MEDLINE, EMBASE and Cochrane databases from their inception to August 2020. The included studies were prospective or retrospective cohort studies that reported the event rate of AMI in COVID-19 patients. Data from each study were combined using random-effects to calculate the pooled incidence with 95% confidence intervals. Results: We identified twenty-seven studies consisting of 8971 hospitalized COVID-19-infected patients. The study demonstrated that 20.0% (95% CI 16.1–23.8% with substantial heterogeneity (I2 = 94.9%)) of hospitalized COVID-19 patients had AMI. In addition, our meta-regression suggested that older age, male and comorbidities were associated with a higher risk of AMI. Conclusion: The incidence of COVID-19-related myocardial injury ranges from 16.1–23.8%. Further larger studies are anticipated, as the pandemic is still ongoing.

Objective: This systematic review and meta-analysis aimed to determine the traumatic macular hole (TMH) closure rate and visual acuity (VA) improvement rate by comparing two treatment methods for TMH: vitrectomy and observation for spontaneous closure.Methods: PubMed, Cochrane, Web of Science Library, Embase, CNKI, Wanfang, VIP, and Sino Med were systematically searched from their inception to June 10, 2021. Studies in the surgery group (n = 32) and studies in the observation group (n = 12) were meta-analyzed. The primary outcomes were the TMH closure and VA improvement rates in the surgery and observation groups. The secondary outcomes were best-corrected visual acuity (BCVA) improvement in the surgery group. Stata software (version 15.1) was used for the analyses.Results: Thirty-six studies that included 1,009 eyes were selected for this meta-analysis, among which 33 were retrospective studies and 3 were prospective studies. The meta-analysis showed that the random-model pooled event rate for TMH closure was 0.37 (95% confidence interval [CI], 0.26–0.48) in the observation group, while it was 0.9 (95% CI, 0.85–0.94) in the surgery group. The fixed-model pooled event rate for VA improvement was 0.39 (95% CI, 0.33–0.45) in the observation group, while the random-model pooled event rate of VA improvement for the surgery group was 0.72 (95% CI, 0.63–0.80). The pooled event rate for BCVA improvement in the surgery group was 0.39 (95% CI, 0.33–0.46).Conclusions: This meta-analysis suggests that TMH hole closure and VA improvement rates in the surgery group were significantly higher than those in the observation group. Vitrectomy is an effective method for treating TMH. However, further randomized controlled trials (RCTs) are required to evaluate the efficacy and safety of surgery and observation for TMH treatment.Systematic Review Registration:https://www.crd.york.ac.uk/PROSPERO/#recordDetails, identifier: CRD42021276684.
