Association between circle of Willis and ischemic stroke: a systematic review and meta-analysis

Abstract Background Circle of Willis is the main structure that provides constant and regular blood flow to the brain, protects the brain from ischemia. Stroke has remained the second leading cause of death globally in the last fifteen years. It is the fifth leading cause of death in the United States. It is also the leading cause of serious adult disability. Interlinked problems related to ischemic stroke are become increasing nowadays. Strong evidence is needed about the pooled measure of association between the circle of Willis (COW) and ischemic stroke. Therefore, this systematic review and meta-analysis were intended to provide compressive and up to date evidence on the association between the variations of COW and ischemic stroke using the available studies. Methods PubMed, Google Scholar, Science Direct, and Cochrane Library databases were systematically searched. All essential data were extracted using a standardized data extraction template. The heterogeneity across studies was assessed by using the Cochrane Q test statistic, I2 test statistic, and P-values. A fixed-effect model was used to estimate the pooled effect of the measure association between COW and ischemic stroke. Results In this meta-analysis, 2,718 participants were involved. The pooled measure of association between COW and ischemic stroke was 1.38 (95% CI 0.87, 2.19). Therefore, this indicated that the presence of any variation in COW was 1.38 times more likely to develop ischemic stroke as compared to the patent COW. The presence of hypoplasia/incompleteness in a posterior communicating artery (PcomA) [Pooled OR: 1.34 (95% CI 0.80, 2.25)] and anterior communicating artery (AcomA) [Pooled OR: 1.32 (95% CI 0.81, 2.19)] were a contributing factor for the development of ischemic stroke. Hypertension was the most common comorbid condition, followed by diabetes mellitus, smoking, coronary artery disease, and hyperlipidemia. Conclusions There was a non-significant positive association between COW variation and ischemic stroke in this meta-analysis.

The Impact

Introduction: In the United States, over 1,000,000 total joint arthroplasty (TJA) surgeries are performed annually and has been forecasted that this number will exceed 4,000,000 by the year 2030. Many different types of dressing exist for use in TJA surgery, and it is unclear if any of the newer, hydrofibre dressings are superior to traditional dressings at reducing rates of infections or improving wound healing. Thus, the aim of this systematic review and meta-analysis was to assess the impact of hydrofiber dressings on reducing complications. Methods: A systematic review and meta-analysis was performed using the online databases MEDLINE and the Cochrane Library. Randomized controlled trials (RCTs) comparing hydrofibre dressings to a standard dressing were included. Summary measures are reported as odds ratios (ORs) and mean differences (MDs) with 95% confidence intervals (CIs). Our primary outcome was prosthetic joint infection (PJI). Secondary outcomes included blisters, dressing changes and wound irritation. Results: 5 RCTs were included. Hydrofibre dressing had no observable effect on PJI or wound irritation (OR 0.53; 95% CI, 0.14–1.98; p = 0.35). Hydrofibre dressings reduced the rate of blisters (OR 0.36; 95% CI, 0.14–0.90; p = 0.03) and number of dressing changes (MD -1.89; 95% CI, -2.68 to -1.11). Conclusions: In conclusion, evidence suggests hydrofibre dressings have no observable effect on PJI and wound irritation. Evidence for reduction in blisters and number of dressings is modest given wide CIs and biased trial methodologies. Use of hydrofibre dressings should be considered inconclusive for mitigating major complications in light of current best evidence.

Term Newborns

Background: Anterior fontanel is an integral element of an infant craniofacial system. There are six fontanels in the newborn skull, namely anterior, posterior, two mastoid, and two sphenoid fontanels. The anterior fontanel is the largest, prominent, and most important for clinical evaluation. Sex, race, genetics, gestational age, and region are the principal factors that influence anterior fontanel size. There exist inconclusive findings on the size of anterior fontanel in newborns. Therefore, this systematic review and meta-analysis aimed to determine the pooled mean size of anterior fontanel among term newborns and to identify the pooled mean difference of anterior fontanel size between males and females.Methods: PubMed/Medline, Google Scholar, Science Direct, JBI Library, embase, and Cochrane Library databases were systematically searched. All essential data were extracted using a standardized data extraction format. The heterogeneity across studies was assessed using the Cochrane Q test statistic, I2 test statistic, and p-values. A fixed-effect model and random effect model were used to estimate the pooled mean size of anterior fontanel and the pooled mean difference between male newborns and female newborns, respectively. To deal with heterogeneity, sub-group analysis, meta-regression analysis, and sensitivity analysis were considered. JBI quality appraisal checklist was used to evaluate the quality of studies.Results: In this meta-analysis, 8, 661 newborns were involved in twenty-six studies. Among studies, 13 conducted in Asia, 7 in Africa, 5 in America, and 1 in Europe. The pooled mean size of anterior fontanel was 2.58 cm (95% CI: 2.31, 2.85 cm). The pooled mean size of anterior fontanel for Asia, Africa, America, and Europe region was 2.49, 3.15, 2.35, and 2.01 cm, respectively. A statistically significant mean difference was detected between male and female newborns (D + L pooled MD = 0.15 cm, 95% CI: 0.02, 0.29 cm).Conclusion: The pooled estimate of this review does provide the mean value of the anterior fontanel size in the newborns. There was a statistically significant mean fontanel size difference between male and female newborns. Therefore, male newborns had a significantly larger mean size than female newborns.

Background: In the latest 2017 American Heart Association guidelines for Kawasaki disease (KD), there are no recommendations regarding the early administration of intravenous immunoglobulin (IVIG). Therefore, the purpose of this systematic review and meta-analysis was to investigate the effects of early IVIG therapy on KD.Methods: We searched databases including the PubMed, Medline, the Cochrane Library, and the Clinicaltrials.gov website until July 2019.Results: Fourteen studies involving a total of 70,396 patients were included. Early treatment with IVIG can lead to an increased risk of IVIG unresponsiveness [OR 2.24; 95% CI (1.76, 2.84); P = 0.000]. In contrast to the studies performed in Japan [OR 1.27; 95% CI (0.98, 1.64); P = 0.074] that found no significant difference in coronary artery lesions (CAL) development, studies conducted in China [OR 0.73; 95% CI (0.66, 0.80); P = 0.000] and the United States [OR 0.50; 95% CI (0.38, 0.66); P = 0.000] showed a reduced risk in the occurrence of CAL with early IVIG treatment.Conclusions: At present, the evidence does not support the treatment with IVIG in the early stage of the onset of KD. But, early IVIG treatment could be a protective factor against the development of CAL, which needs to be further clarified.

Abstract Atrial fibrillation(AF) increases the risk of ischemic stroke and systemic embolism in patients. Moreover, Asian patients with AF are more likely to have ischemic stroke than non-Asian patients. Oral anticoagulants could effectively prevent thrombotic events. Dabigatran and Rivaroxaban are two most commonly used novel oral anticoagulants (NOACs) in Asia, but those clinicial studies in relation with them are mostly in American and European countries. Therefore, whether there are differences between Dabigatran and Rivaroxaban among Asian patients with AF in terms of efficacy and safety is still unknown. This systematic review and meta-analysis will mainly assess clinical efficacy and safety of Dabigatran versus Rivaroxaban in Asian patients with AF by a pooled analysis. We will follow the PRISMA (preferred reporting items for systematic reviews and meta-analyses) and the reporting MOOSE (Meta-analyses of Observational Studies in Epidemiology) when performing this study. Then Cochrane Library,Web of Science, PubMed and China national knowledge infrastructure will be searched for eligible retrospective investigation that report the efficacy and safety outcomes of AF patients who utilised Dabigatran or Rivaroxaban for stroke prevention in Asian countries. The abovementioned database will be comprehensively searched from inception to September 30, 2019 to locate all potentially eligible studies. Outcome measures will include safety and efficacy indicators. Safety indicators include intracranial hemorrhage, major bleeding and gastrointestinal bleeding. Efficacy indicators include systemic embolism and stroke. New evidence for clinical profile of Dabigatran versus Rivaroxaban in AF patients will be provided for decision-making of Asian patients.PROSPERO registration number: CRD42020156197

Background: Intravenous thrombolysis is the preferred clinical treatment for acute ischemic stroke. Alteplase is an intravenous thrombolytic drug used in clinical practice. Recently, studies have shown the efficacy of another intravenous thrombolytic drug, tenecteplase, and have reported that the risk of bleeding is low. However, at present, Chinese and international research has yielded controversial results regarding the efficacy and risks of tenecteplase. Therefore, this systematic review and meta- analysis of the efficacy and safety of tenecteplase were performed. Methods: PubMed, the Cochrane Library, MEDLINE, the Wanfang Database and CNKI were searched for all studies on the thrombolytic treatment of acute ischemic stroke. All studies published in English prior to March 2021 were retrieved. The studies were screened and selected based on the inclusion and exclusion criteria. Then, the data were extracted and recorded by trained researchers. RevMan 5.4 statistical software was used to analyze the data on the 24h recanalization rate, early neurological improvement (24h reduction in the National Institutes of Health Stroke Scale [NIHSS] score of at least 8 points or 24 h NIHSS score of 0~1 point), mRS score at 90 days, intracranial hemorrhage, symptomatic intracranial hemorrhage and mortality in the tenecteplase group and alteplase group. Results: A total of 565 related studies were identified through the initial searches in each database. The citations of meta-analyses and related reviews were screened for additional eligible articles. Eventually, 9 high-quality English-language articles that included 2149 patients with acute ischemic stroke (including 1035 in the tenecteplase group and 1046 in the alteplase group)were included in this meta-analysis. The meta-analysis results were as follows: (1) Efficacy: The 24 h recanalization rate with regard to vascular recanalization was significantly better in the tenecteplase group than in the alteplase group(OR = 1.83, 95% CI: 1.23~2.72, z = 2.97, P = 0.003). There was significantly greater improvement in early neurological function in the tenecteplase group than in the alteplase group (OR= 1.34, 95% CI: 1.11~1.63, Z=3.00, P =0.003). There were no significant differences in 90-day mRS scores between the two groups (mRS score =0-1, OR = 1.20, 95% CI: 0.99~1.46, z = 1.82, p = 0.07; mRS score =0-2, OR = 1.17, 95% CI: 0.94~1.45, z = 1.38, p = 0.17). However, the subgroup analysis showed that the 90-day mRS score of the 0.25 mg/kg tenecteplase group was significantly different from that of groups treated with other doses of tenecteplase (OR = 1.48, 95% CI: 1.01~2.03, z = 2.03, p = 0.04). (2) Safety: The incidences of any intracranial hemorrhage (OR = 0.91, 95% Ci: 0.55~1.49, z = 0.39, p = 0.70), symptomatic intracranial hemorrhage (OR = 1.21, 95% CI: 0.63~2.32, z = 0.56 P = 0.57), and mortality (OR = 0.85, 95% CI: 0.57~1.26, z = 0.82, p = 0.41) were not significantly different between the tenecteplase and alteplase groups. Conclusions: Tenecteplase can significantly increase the 24-hour vascular recanalization rate and improve the neurological prognosis of patients with acute ischemic stroke and it does not increase the risk of intracranial hemorrhage or mortality.

Abstract Background and objectiveThrombin-antithrombin complex (TAT) is a prethrombotic marker, and its application in ischemic stroke is still uncertain. The purpose of this systematic review and meta-analysis is to evaluate the relationship between plasma TAT and ischemic stroke base on the current evidence.MethodsA systematic literature search was conducted for searching the relative studies that investigated the association of TAT and ischemic stroke in PubMed, EMBASE, and Cochrane library databases. Mean difference and 95% confidence interval as the effect sizes were synthesized by random effects model in Review Manager (RevMan) Version 5.4. Then, the heterogeneity was investigated using the Chi-square test and the possible sources of heterogeneity were explored by sensitivity analysis. The publication bias was estimated through Begg’s and Egger’s tests.ResultsA total of 12 eligible studies were included involving 1431 stroke cases and 532 healthy controls, of which six studies were eventually included in the meta-analysis. Plasma TAT in patients with ischemic stroke was significantly higher than that in healthy controls (MD 5.31, 95% CI =4.12-6.51, P<0.0001, I2=97.8 %). There is a difference of TAT level in the same period among cardioembolic, lacunar and atherothrombotic stroke (all P<0.0001), in which the cardioembolic stroke with the highest level. Meanwhile, it is significant of TAT levels among various phases of cardioembolic stroke and the acute phase are markedly elevated (MD 7.75, 95CI%, 6.07-9.43, P<0.001). However, no difference was found in the atherothrombotic (P=0.13) and lacunar stroke (P=0.34). Besides, the higher TAT level is closely related to the poor prognosis of patients with ischemic stroke, including higher recurrence, mortality, unfavorable recovery (modified Rankin scale >2), and poor revascularization.ConclusionsThis study suggested that plasma TAT levels are different in ischemic stroke subtypes, which are closely associated with the progression and might have an effect on the prognosis.

Background: Cardiac complications after a stroke are the second leading cause of death worldwide, affecting the treatment and outcomes of stroke patients. Cardiac biomarkers such as cardiac troponin (cTn), brain natriuretic peptide (BNP), and N-terminal pro-brain natriuretic peptide (NT-proBNP) have been frequently reported in patients undergoing a stroke. The aim of the present study is to meta-analyze the relationship between changes in such cardiac biomarkers and stroke and to present a systematic review of the previous literature, so as to explore the brain–heart axis. Methods: We searched four online databases pertinent to the literature, including PubMed, Embase, the Cochrane Library, and the Web of Science. Then, we performed a meta-analysis to investigate changes in cTn, BNP, and NT-proBNP associated with different types of stroke. Results and Conclusions: A significant increase in cTnI concentration was found in patients exhibiting a brain hemorrhage. BNP increased in cases of brain infarction, while the NT-proBNP concentration was significantly elevated in patients suffering an acute ischemic stroke and brain hemorrhage, indicating cardiac damage and dysfunction after a stroke. Our analysis suggests that several potential mechanisms may be involved in the brain–heart axis. Finally, clinicians should pay careful attention to monitoring cardiac function in the treatment of cerebrovascular diseases in order to provide a timely and more accurate treatment.

Abstract BackgroundAcute ischemic stroke (AIS) is a major contributor to global morbidity and mortality, and mechanical thrombectomy (MT) is an effective treatment for AIS. AIS caused by tandem intracranial and extracranial occlusions are not rare. Evidence for optimal MT strategy regarding order of treatment, including antegrade (extracranial first) or retrograde (intracranial first) approach is lacking. Therefore, a systematic review and meta-analysis is necessary to compare the two approaches for optimal management of tandem lesions in AIS.MethodsThis study will be performed with accordance to the PRISMA statement. Major databases including PubMed, Web of Science, Embase, and the Cochrane Library will be used for literature search. Randomized controlled trials and high-quality observational studies will be included. Risk of bias will be assessed using the Cochrane Collaboration criteria or Newcastle–Ottawa Scale according to type of study. Two reviewers will independently screen for eligible studies and perform data extraction. The primary outcomes are successful recanalization at post-intervention, and favorable outcome at 3-month follow-up. Secondary outcomes include duration of onset to arrival, onset to puncture, onset to recanalization, intracerebral hemorrhage, procedure and device related complications and mortality at 3-month follow-up. We will assess heterogeneity using the I2 statistic. Subgroup and sensitivity analyses will be performed to explore the sources of heterogeneity. Specific results will be described in narrative form when insufficient suitable studies are available for meta-analysis.DiscussionThis study will provide a reliable evidence base for antegrade or retrograde approach for the management of tandem lesions in AIS by synthesizing evidence from current pieces of literature comparing the two approaches, and also will provide updated clinical evidence of strategy selection and decision-making for this special group of patients.

AbstractBackgroundCOVID-19 infections are seen across all age groups but they have shown to have a predisposition for the elderly and those with underlying comorbidities. Patients with severe COVID-19 infections and comorbidities are more prone to respiratory distress syndrome (ARDS), mechanical ventilator use and ultimately succumb to these complications. Little evidence exists of the prevalence of underlying lung comorbidities among COVID-19 patients and associated mortality.MethodsWe performed a systematic review of the literature including PubMed (Medline), Embase (Ovid), Google Scholar and Cochrane Library. The last date for our search was 29th April 2020. We included all original research articles on COVID-19 and calculated prevalence of chronic lung disease patients among COVID-19 patients using random effects model. Further we assessed for mortality rates among COVID-19 patients associated with these lung comorbidities.ResultsThe authors identified 29 articles that reported prevalence of chronic lung conditions among COVID-19 patients. Among those, 26 were from China and 3 from the United States. The pooled prevalence of lung comorbidities including Asthma, COPD, and lung cancer was 3% (95% CI=0-14%), 2.2% (95% CI=0.02-0.03%) and 2.1% (95% CI=0.00-0.21%) respectively. Mortality rates associated with these comorbidities was 30% (41/137) for COPD and 19% (7/37) for lung cancer respectively. No mortality rates were reported for patients with asthma.ConclusionThis study offers latest evidence of prevalence of chronic lung conditions among patients with COVID-19. Asthma, followed by COPD and lung cancer, was the most common lung comorbidity associated with COVID-19, while the higher mortality rate was found in COPD. Future studies are needed to assess other lung comorbidities and associated mortality among patients diagnosed with COVID-19.

Objective: This review aims to study the receptor's family and functions most related to COVID-19 infection, also suggesting the tissue and cell location that the majority of COVID-19 receptors are mainly expressed. Methods: This systematic review (PROSPERO: CRD42020210643) is according to PRISMA guidelines. PubMed, Cochrane, SciELO, Lilacs, Web of Science, and DOAJ databases were used. Clinical trials and research articles studying receptors related to COVID-19 were included in this review. R programming language was used to elaborate charts and receptors network and SPSS(26v) software was used to perform statistical analyses. Results: The majority of studies regarding the involvement of receptors in COVID-19 included plasma receptors and G protein-coupled receptor families (p<0.05). These receptors are highly expressed in the brain (24%) and 80% of them can interact with each other in a protein network, exerting some regulatory effects in various tissues. The main influential receptor on the network of receptors involved in COVID-19 was the EGFR and the majority of receptors were associated with pathological processes in the disease (p<0.05), including the amplification of inflammatory responses in COVID-19, which may be related to neurological disorders in some cases. Humans from the United States, Spain, and Brazil were the most used model in studies adressing receptors involved in COVID-19 (p<0.05). Conclusions: Plasma receptors and G protein-coupled receptors, especially the EGFR, and involved with pathological effects on the COVID-19 inflammatory process in the brain have shown significant importance in this review.
