Abstract Background: To evaluate myocardial injury in Atrial flutter (AFL) patients undergoing Radiofrequency ablation (RF) and cryoablation (CRYO) treatments. Methods: We conducted a systematic search on PubMed, Embase, Cochrane Library, and CBM databases. All relevant clinical trials (up to October 2018) on myocardial injury in AFL patients were retrieved and subsequent results analyzed with a random-effects model or a fixed-effects model. Results: A total of eight clinical trials with a sample size of 644 patients, were identified and incorporated in the present study. The results indicated no significant differences in creatine kinase (CK) levels (mean difference (MD) = 62.74, P=0.46; 4–6 h and MD = 30.73, P=0.49; 12–24 h after ablation), creatine kinase MB(CK-MB) levels (MD = 17.32, P=0.25; 12–24 h post-ablation), troponinI (TnI) levels (MD = 0.12, P=0.08; 6 h after ablation), and troponin T (TnT) levels (MD = 0.30, P=0.08; 4–6 h post-ablation) between the two treatment approaches. However, patients receiving CRYO xhibited higher levels of CK (MD = 179.54, P=0.04; tested immediately after the procedure), CK-MB (MD = 10.08, P=0.004) 4–6 h after ablation, and TnT (MD = 0.19, P=0.002) tested the next morning. Moreover, those patients had a significantly reduced pain perception (odds ratio (OR) = 0.05, P=0.04) compared with those in the RF group. Conclusion: These results indicate that CRYO in comparison with RF significantly increases myocardial injury in AFL patients. Additionally, it decreases pain perception during the procedure. Further large-sampled studies are needed to support these findings.

Background: Nervous and muscular adverse events (NMAEs) have garnered considerable attention after the vaccination against coronavirus disease (COVID-19). However, the incidences of NMAEs remain unclear. We aimed to calculate the pooled event rate of NMAEs after COVID-19 vaccination. Methods: A systematic review and meta-analysis of clinical trials on the incidences of NMAEs after COVID-19 vaccination was conducted. The PubMed, Medline, Embase, Cochrane Library, and Chinese National Knowledge Infrastructure databases were searched from inception to 2 June 2021. Two independent reviewers selected the study and extracted the data. Categorical variables were analyzed using Pearson’s chi-square test. The pooled odds ratio (OR) with the corresponding 95% confidence intervals (CIs) were estimated and generated with random or fixed effects models. The protocol of the present study was registered on PROSPERO (CRD42021240450). Results: In 15 phase 1/2 trials, NMAEs occurred in 29.2% vs. 21.6% (p < 0.001) vaccinated participants and controls. Headache and myalgia accounted for 98.2% and 97.7%, and their incidences were 16.4% vs. 13.9% (OR = 1.97, 95% CI = 1.28–3.06, p = 0.002) and 16.0% vs. 7.9% (OR = 3.31, 95% CI = 2.05–5.35, p < 0.001) in the vaccine and control groups, respectively. Headache and myalgia were more frequent in the newly licensed vaccines (OR = 1.97, 95% CI = 1.28–3.06, p = 0.02 and OR = 3.31, 95% CI = 2.05–5.35, p < 0.001) and younger adults (OR = 1.40, 95% CI = 1.12–1.75, p = 0.003 and OR = 1.54, 95% CI = 1.20–1.96, p < 0.001). In four open-label trials, the incidences of headache, myalgia, and unsolicited NMAEs were 38.7%, 27.4%, and 1.5%. Following vaccination in phase 3 trials, headache and myalgia were still common with a rate of 29.5% and 19.2%, although the unsolicited NMAEs with incidence rates of ≤ 0.7% were not different from the control group in each study. Conclusions: Following the vaccination, NMAEs are common of which headache and myalgia comprised a considerable measure, although life-threatening unsolicited events are rare. NMAEs should be continuously monitored during the ongoing global COVID-19 vaccination program.

Abstract Context.—Rapid diagnosis of acute myocardial infarction in patients presenting to emergency departments (EDs) with chest pain may determine the types, and predict the outcomes of, the therapy those patients receive. The amount of time consumed in establishing diagnoses of acute myocardial infarction may depend in part on that consumed in the generation of the blood test results measuring myocardial injury. Objective.—To determine the normative rates of turnaround time (TAT) for biochemical markers of myocardial injury and to examine hospital and laboratory practices associated with faster TATs. Design.—Laboratory personnel in institutions enrolled in the College of American Pathologists Q-Probes Program measured the order-to-report TATs for serum creatine kinase–MB and/or serum troponin (I or T) for patients presenting to their hospital EDs with symptoms of acute myocardial infarction. Laboratory personnel also completed detailed questionnaires characterizing their laboratories' and hospitals' practices related to testing for biochemical markers of myocardial injury. ED physicians completed questionnaires indicating their satisfaction with testing for biochemical markers of myocardial injury in their hospitals. Setting.—A total of 159 hospitals, predominantly located in the United States, participating in the College of American Pathologists Q-Probes Program. Results.—Most (82%) laboratory participants indicated that they believed a reasonable order-to-report TATs for biochemical markers of myocardial injury to be 60 minutes or less. Most (75%) of the 1352 ED physicians who completed satisfaction questionnaires believed that the results of tests measuring myocardial injury should be reported back to them in 45 minutes or less, measured from the time that they ordered those tests. Participants submitted TAT data for 7020 troponin and 4368 creatine kinase–MB determinations. On average, they reported 90% of myocardial injury marker results in slightly more than 90 minutes measured from the time that those tests were ordered. Among the fastest performing 25% of participants (75th percentile and above), median order-to-report troponin and creatine kinase–MB TATs were equal to 50 and 48.3 minutes or less, respectively. Shorter troponin TATs were associated with performing cardiac marker studies in EDs or other peripheral laboratories compared to (1) performing tests in central hospital laboratories, and (2) having cardiac marker specimens obtained by laboratory rather than by nonlaboratory personnel. Conclusion.—The TAT expectations of the ED physicians using the results of laboratory tests measuring myocardial injury exceed those of the laboratory personnel providing the results of those tests. The actual TATs of myocardial injury testing meet the expectations of neither the providers of those tests nor the users of those test results. Improving TAT performance will require that the providers and users of laboratory services work together to develop standards that meet the needs of the medical staff and that are reasonably achievable by laboratory personnel.

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.
