OBJECTIVEThe role of mechanical thrombectomy in pediatric acute ischemic stroke is uncertain, despite extensive evidence of benefit in adults. The existing literature consists of several recent small single-arm cohort studies, as well as multiple prior small case series and case reports. Published reports of pediatric cases have increased markedly since 2015, after the publication of the positive trials in adults. The recent AHA/ASA Scientific Statement on this issue was informed predominantly by pre-2015 case reports and identified several knowledge gaps, including how young a child may undergo thrombectomy. A repeat systematic review and meta-analysis is warranted to help guide therapeutic decisions and address gaps in knowledge.METHODSUsing PRISMA-IPD guidelines, the authors performed a systematic review of the literature from 1999 to April 2019 and individual patient data meta-analysis, with 2 independent reviewers. An additional series of 3 cases in adolescent males from one of the authors’ centers was also included. The primary outcomes were the rate of good long-term (mRS score 0–2 at final follow-up) and short-term (reduction in NIHSS score by ≥ 8 points or NIHSS score 0–1 at up to 24 hours post-thrombectomy) neurological outcomes following mechanical thrombectomy for acute ischemic stroke in patients < 18 years of age. The secondary outcome was the rate of successful angiographic recanalization (mTICI score 2b/3).RESULTSThe authors’ review yielded 113 cases of mechanical thrombectomy in 110 pediatric patients. Although complete follow-up data are not available for all patients, 87 of 96 (90.6%) had good long-term neurological outcomes (mRS score 0–2), 55 of 79 (69.6%) had good short-term neurological outcomes, and 86 of 98 (87.8%) had successful angiographic recanalization (mTICI score 2b/3). Death occurred in 2 patients and symptomatic intracranial hemorrhage in 1 patient. Sixteen published thrombectomy cases were identified in children < 5 years of age.CONCLUSIONSMechanical thrombectomy may be considered for acute ischemic stroke due to large vessel occlusion (ICA terminus, M1, basilar artery) in patients aged 1–18 years (Level C evidence; Class IIb recommendation). The existing evidence base is likely affected by selection and publication bias. A prospective multinational registry is recommended as the next investigative step.

SUMMARY Published studies have reported variable results on the association between duration of proton pump inhibitor (PPI) use and the risk of dementia. An extensive literature search was performed in PubMed, Embase, Google Scholar, and Cochrane for studies examining the risk of cognitive decline and dementia among PPI users versus non-PPI users in prospective studies. Retrospective database linkage studies, case reports, case series, editorials, uncontrolled cohort studies, cross-sectional studies, and review articles were excluded. Primary outcome was pooled hazard rate (HR) of any dementia among PPI users compared with non-PPI users. Secondary outcomes were pooled HR of Alzheimer’s dementia (AD) and risk with long-term PPI follow-up (more than 5 years) studies. Meta-analysis outcomes, heterogeneity (I2), and meta-regression (for the effect of covariates) were derived by statistical software R and Open meta-analyst. A total of six studies (one RCT and five prospective) with 308249 subjects, average age of 75.8 ± 5.2 years, and follow-up of 5 (range 1.5–11) years were included in the analysis. Pooled HR of any dementia was 1.16 (n = 6, 95% confidence interval (CI) = 0.86–1.47). Results remained unchanged when only studies with long-term PPI use (more than 5 years) were analyzed (n = 4, pooled HR 1.10, 95% CI 0.66–1.53). Finally, the pooled HR for AD was 1.06 (n = 3, 95% CI 0.70–1.41). There was substantial heterogeneity among inclusion studies (I2 = 93%). Meta-regression did not demonstrate a significant role of age at study start (P = 0.1) or duration of PPI use (P = 0.62) to incident dementia. The results of this systematic review and meta-analysis do not show a significant relationship between PPI use and dementia in prospective studies with at least a 5-year follow-up.

Mechanical thrombectomy (MT) has become the standard treatment for large vessel occlusion (LVO) in acute ischemic stroke (AIS). Few studies have investigated long-term outcomes for AIS treated with MT. Therefore, a pooled meta-analysis using data from randomized clinical trials (RCT) was performed to assess for long-term clinical outcomes. A systematic literature search was conducted on 27 September 2017, by searching the English literature in the Cochrane Library, MEDLINE, and Embase for RCTs investigating long-term outcomes (greater than standard 3-month timepoint) of endovascular intervention versus medical management for patients with AIS. The study was carried out according to PRISMA guidelines and random effects analysis was carried out to account for heterogeneity. Three trials were included: IMS III, MR CLEAN, and REVASCAT, comprising a total of 1,362 patients. Long-term clinical outcomes were available for 1-year follow-up in IMS III and REVASCAT and at 2 years in MR CLEAN. Functional independence at long-term follow-up favored endovascular stroke intervention (OR 1.51; p = 0.02). When stratified by LVO inclusion criteria, greater endovascular functional independence benefits were observed (OR 1.85; p = 0.0005). There was a significant difference between the 2 arms in favor of endovascular therapy for the quality of life at long-term follow-up (mean difference 0.11; p = 0.0002). No difference in mortality at long-term follow-up was observed (OR 0.82; p = 0.12). We conclude that endovascular therapy results in favorable outcomes at long-term follow-up for patients with acute ischemic stroke compared to standard medical treatment alone and that the 90-day timepoint offers a fair representation of the long-term outcomes.

AbstractBackgroundPrevious studies reported the recurrence of coronavirus disease 2019 (COVID-19) among discharge patients. This study aimed to examine the characteristic of COVID-19 recurrence cases by performing a systematic review and meta-analysis.MethodsA systematic search was performed in PubMed and Embase and gray literature up to September 17, 2020. A random-effects model was applied to obtain the pooled prevalence of disease recurrence among recovered patients and the prevalence of subjects underlying comorbidity among recurrence cases. The other characteristics were calculated based on the summary data of individual studies.ResultsA total of 41 studies were included in the final analysis, we have described the epidemiological characteristics of COVID-19 recurrence cases. Of 3,644 patients recovering from COVID-19 and being discharged, an estimate of 15% (95% CI, 12% to 19%) patients was re-positive with SARS-CoV-2 during the follow-up. This proportion was 14% (95% CI, 11% to 17%) for China and 31% (95% CI, 26% to 37%) for Korea. Among recurrence cases, it was estimated 39% (95% CI, 31% to 48%) subjects underlying at least one comorbidity. The estimates for times from disease onset to admission, from admission to discharge, and from discharge to RNA positive conversion were 4.8, 16.4, and 10.4 days, respectively.ConclusionThis study summarized up-to-date evidence from case reports, case series, and observational studies for the characteristic of COVID-19 recurrence cases after discharge. It is recommended to pay attention to follow-up patients after discharge, even if they have been in quarantine.

Meta Analyses

Objective: Both true and false extracranial carotid artery aneurysms (ECAA) are a potential source of morbidity and mortality. While ECAA have historically been treated surgically, endovascular reconstruction with stenting is an emerging treatment option. The aim of our study was to report clinical/radiologic outcomes following endovascular repair of ECAAs. Methods: A comprehensive systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Results: A total of 68 case reports and case series, comprising 162 patients, were included. Most patients presented with at least one symptom or sign related to the ECAA (89.5%; N = 145/162). In 42.6% (N = 69/162) and 46.3% (N = 75/162) of the cases polytetrafluoroethylene covered and uncovered stents were deployed respectively. Immediate post-procedural imaging demonstrated complete aneurysm exclusion in 86.4% (N = 140/162) of the cases and minimal filling of the aneurysm sack in 10.5% (N = 17/162) of all cases. Perioperative adverse event rates were 3.1% for stroke, 1.2% for transient ischemic attack (TIA) and 4.3% for mortality. During a mean follow-up of 21.8months, there were additionally observed one stroke, two TIAs and three deaths. Overall 88.6 % of the patients (N = 117/132) remained asymptomatic, partially recovered or at least did not suffer from new neurologic deficits during follow up, with no signs of stenosis or occlusion of the carotid artery. Conclusions: Endovascular stenting for the treatment of ECAAs is feasible with acceptable short- and long-term clinical and radiologic outcomes. Prospective real-world studies are needed to further validate the safety and the long-term patency of endovascular repair.

The Impact

Background: A number of studies have explored the prognostic role of CRP in patients with acute ischemic stroke, however, the results have been inconclusive. The aim of our study was to investigate the impact of infection on the association between CRP and 3-month functional outcome by performing a registry study and systematic review. Methods: Patients admitted within 24 hours of acute ischemic stroke onset and had CRP measured within 24 hours after admission were included. Patients admitted between June 2016 and December 2018 in Chengdu Stoke Registry were enrolled. The PubMed database was searched up to July 2019 to identify eligible studies. Poor outcome was defined as modified Rankin Scale scores at 3-month more than 3. Results: Totally, 368 patients in the registry and 18 studies involving 15238 patients in the systematic review were included. A statistically significant association between CRP values on admission and 3-month poor outcome in patients without infection was found, both in our registry (CRP per 1-mg/L increment, OR 1.04, 95% CI 1.01 to 1.07, p=0.008) and meta-analysis (CRP per 1-mg/dL increment, OR 1.66 [95% CI 1.37 to 2.01, p<0.001]). In patients with infection, CRP was not associated with a 3-month poor outcome according to registry data (OR 1.00, 95% CI 0.99 to 1.01, p=0.663) and meta-analysis (OR 1.01, 95% CI 0.99 to 1.01, p=0.128). Conclusion: High CRP value was independently associated with a 3-month poor outcome after stroke in patients without infection. Further studies are required to examine the value of infection on CRP measures and long-term functional outcomes.

BackgroundFew studies have compared technical success and effectiveness of transradial access (TRA) versus transfemoral access (TFA) for mechanical thrombectomy (MT) for acute ischemic stroke (AIS). We compared the two approaches for technical success, effectiveness, and outcomes.MethodsWe retrospectively compared TRA with TFA for AIS MT at our institute. We additionally performed a systematic review and meta-analysis of studies describing the use of TRA alone or in comparison with TFA for MT. Primary outcomes included rate of successful reperfusion (thrombolysis in cerebral infarction (TICI) >2b), number of passes, access-site complications, and 3- month mortality and favorable functional outcomes (modified Rankin Scale (mRS) score 0–2).ResultsA total of 222 consecutive patients (TRA=93, TFA=129) were included in our case series. The rate of successful reperfusion was significantly higher for the TFA cohort (91.4% vs 79.6%, P=0.01) with lower mean number of passes (1.8±1.2 vs 2.4±1.6, P=0.014). Three-month mortality in the TFA group was lower (22.1% vs 40.9% for the TRA cohort (P=0.004), with a higher rate of favorable functional outcomes (51.3% vs 34.1%, P=0.015). A meta-analysis of 10 studies showed significant heterogeneity in rates of successful reperfusion (57.1% to 95.6%, heterogeneity=67.55%, P=0.001). None of the previous comparative studies reported 3-month mortality and functional outcomes.ConclusionsThis case series demonstrate a higher successful reperfusion rate, fewer passes, lower 3-month mortality, and improved 3-month functional outcomes with TFA. The systematic review highlights the inadequacy of existing evidence. Prospective comparative studies are needed before a ‘radial-first’ approach can be adopted for stroke intervention.

Background: Decompressive hemicraniectomy (DH) has been performed for some cases of acute ischemic stroke in patients with coronavirus disease 2019 (COVID-19) infection, but there is little information about the clinical course and outcomes of these patients. Case Description: We report a case of a 36-year-old woman with COVID-19 infection who developed stroke like symptoms while under home quarantine. Cranial CT scan showed an acute left internal carotid artery (ICA) infarct. She subsequently underwent an emergent left DH. Despite timely surgical intervention, she succumbed to chronic respiratory failure. A systematic review of SCOPUS and PubMed databases for case reports and case series of patients with COVID-19 infection who similarly underwent a DH for an acute ischemic infarct was performed. There were eight other reported cases in the literature. The patients’ age ranged from 33 to 70 years (mean 48), with a female predilection (2:1). Respiratory preceded neurologic symptoms in 83% of cases. The ICA was the one most commonly involved in the stroke, and the mean NIHSS score was 20. DH was performed at a mean of 1.8 days post-ictus. Only four out of the nine patients were reported alive at the time of writing. The most common cause of death was respiratory failure (60%). Conclusion: Clinicians have to be cognizant of the neurovascular complications that may occur during the course of a patient with COVID-19. DH for acute ischemic stroke associated with the said infection was reported in nine patients, but the outcomes were generally poor despite early surgical intervention.

Background: Drug-resistant epilepsy (DRE) can affect up to one third of individuals with epilepsy. We conducted a systematic review and meta-analysis of vagus nerve stimulation (VNS), responsive neurostimulation (RNS), and deep brain stimulation (DBS) in patients with DRE to summarize the current evidence on efficacy and tolerability for these neuromodulation modalities. Methods: We searched three online databases with a pre-specified search strategy. We included published randomized controlled trials (RCT) and their open-label extension studies, as well as prospective case series, with samples greater than 20 participants, reporting efficacy and tolerability. Results: We identified 31 studies, six of which are RCTs and 25 prospective observational studies. At long term follow-up, five observational studies for VNS reported a pooled mean decrease in seizure frequency at last follow-up of 35%. In the extension studies for RNS, the median seizure reduction was 53%, 66% and 75.0% at two, five and nine years respectively. For DBS, the median reduction was then 56%, 69% and 75% at two, five and seven years respectively. Conclusions: Neurostimulation modalities are effective for the treatment of DRE, with improving outcomes over time and few major complications. Higher quality long-term data on DBS and RNS suggest larger seizure reduction rates than VNS.
