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.

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.

AbstractObjectiveThe purpose of the present study was to determine whether elevated dietary Na intake could be associated with CVD mortality.DesignWe performed a systematic review and meta-analysis of prospective studies representing the general population. The adjusted relative risks and their 95 % confidence intervals were pooled by the inverse variance method using random-effects models. Heterogeneity, publication bias, subgroup and meta-regression analyses were performed.SettingsMEDLINE (since 1973), Embase (since 1975), the Cochrane Library (since 1976), ISI Web of Science, Google Scholar (until September 2013) and secondary referencing were searched for inclusion in the study.SubjectEleven prospective studies with 229 785 participants and average follow-up period of 13·37 years (range 5·5–19 years).ResultsHigher Na intake was significantly associated with higher CVD mortality (relative risk=1·12; 95 % CI 1·06, 1·19). In the sensitivity analysis, the exclusion of studies with important relative weights did not significantly affect the results (relative risk=1·08; 95 % CI 1·01, 1·15). The meta-regression analysis showed that for every increase of 10 mmol/d in Na intake, CVD mortality increased significantly by 1 % (P=0·016). Age, hypertensive status and length of follow-up were also associated with increased CVD mortality.ConclusionsHigher Na intake was associated with higher CVD mortality in the general population; this result suggests a reduction in Na intake to prevent CVD mortality from any cause.

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.

Poor Outcomes

Abstract Introduction We aimed to determine if patients with CHD are at a higher risk of poor outcomes if they have COVID-19, compared to those without CHD. Method A systematic review was executed using the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. To identify articles related to COVID-19 and CHD, an extensive literature search was performed on EMBASE, Medline, Scopus and Global Health databases using keywords and MeSH terms. Results 12 articles met the inclusion criteria and were included for analysis in this systematic review. Two themes were identified for data extraction: [1] evidence supporting higher risks in CHD patients and [2] evidence against higher risks in CHD patients. After combining the data, there were 99 patients with CHDs out of which 12 required admission to ICU. Conclusions This systematic review suggests that CHD may increase the risk of poor outcomes for those with COVID-19, but also highlights the necessity for more research with larger sample sizes in order to make a more justified conclusion, as the majority of papers that were analysed were case series and case reports. Future research should aim to quantify the risks if possible while accounting for various confounding factors such as age and treatment history.

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.

Summary Introduction: Achalasia may evolve to sigmoid megaesophagus in 10–15% of patients and is usually treated with esophagectomy, which has high morbi-mortality. Many surgeons debate the applicability of the Heller myotomy for treating sigmoid megaesophagus. This study intents to analyze the effectiveness of myotomy for treating patients with sigmoid megaesophagus. Methods: A systematic review and meta-analysis was conducted in PubMed, Cochrane, Lilacs and Embase alongside manual search of references. The inclusion criteria were clinical trials, cohort, case-series; patients with sigmoid megaesophagus and esophageal diameter ≥ 6 cm; and patients undergoing primary myotomy. The exclusion criteria were reviews, case reports, cross-sectional studies, editorials, letters, congress abstracts, full-text unavailability; previous surgical treatment for achalasia; and pediatric or animal model studies. No restrictions on language and date of publication, and no filters were applied. Subgroups analyses were performed to assess the laparoscopic myotomy perioperative outcomes. Besides, subgroup analyses were performed to assess the long-term outcomes of the studies with a follow-up time &gt; 24 months. To verify heterogeneity, the I2 test was used. The random effects were applied, and the fixed model was evaluated as sensitivity analysis. To assess risk of bias and certainty of evidence, the tools ROBINS-I and GRADE were used, respectively. Registration number: CRD42020199667. Results: Sixteen articles were selected, encompassing 350 patients. The mean age ranged from 36 to 61 years old, and the mean follow-up ranged from 16 to 109 months. Complications rate was 0.08 (CI: 0.040–0.153; P = 0.01). Need for retreatment rate was 0.128 (CI: 0.031–0.409; P = 0.01). The probability of good or excellent outcomes after myotomy was 0.762 (CI: 0.703–0.812; P &lt; 0.01). Postoperative mortality rate was 0.008 (CI: 0.004–0.015; P &lt; 0.01). Conclusion: Surgical myotomy is an option for avoiding esophagectomy in achalasia, with a low morbi-mortality rate and good results. It is effective for most patients and only a minority will demand retreatment.

ABSTRACTIntroductionLong-term outcomes among syncope patients are not well studied to guide physicians regarding outpatient testing and follow-up. The objective of this study was to conduct a systematic review for outcomes at 1-year or later among ED syncope patients.MethodsWe searched Cochrane Central, Medline, Medline in Process, PubMed, Embase, and the Cumulative Index to Nursing databases from inception to December 2018. We included studies that reported long-term outcomes among ED syncope patients. We excluded studies on patients <16 years old, studies that included syncope mimickers (pre-syncope, seizure, intoxication, loss of consciousness after head trauma), case reports, letters to the editor, non-English and review articles. Outcomes included death, syncope recurrence requiring hospitalization, arrhythmias and procedural interventions for arrhythmias. Meta-analysis was performed by pooling the outcomes using random effects model.ResultsInitial literature search generated 2,094 articles duplicate removal. Of the 50 articles selected for full-text review, 19 articles with 98,211 patients were included in this review: of which 12 were included in the 1-year outcome meta-analysis. Pooled analysis showed : 7.0% mortality; 16.0% syncope recurrence requiring hospitalization; 6.0% with device insertion. 1-year arrhythmias reported in two studies were 1.1 and 26.4%. Pooled analysis for outcome at 31 to 365 days showed: 5.0% mortality and 1% device insertion. Two studies reported 4.9% and 21% mortality at 30 months and 4.2 years follow-up.ConclusionsAn important proportion of ED syncope patients suffer long-term morbidity and mortality. Appropriate follow-up is needed and future research to identify patients at risk is needed.

Background: Numerous cases of the coronavirus disease 2019 (COVID-19) with autoimmune and rheumatic manifestations have been reported. Despite the available reviews that summarized its autoimmune/rheumatic manifestations, a systematic approach is still lacking. Therefore, we conducted a comprehensive systematic review in order to give an overview upon these rare but clinically significant manifestations.Methods: We performed a literature search of PubMed and EMBASE as of October 9, 2020. All articles relevant to either systemic or organ-specific autoimmune and rheumatic manifestations potentially associated with COVID-19 were collected. The reviewed literature were limited to adults ≥18 years.Results: Although most of the existing evidence was based on case reports or case series without a long-term follow-up, a variety of autoimmune/rheumatic manifestations were associated with COVID-19. The manifestations that have a consistent association with COVID-19 include autoimmune cytopenia, cutaneous vasculitis, encephalitis, and Guillain-Barre syndrome. Such association is conflicting as regards to antiphospholipid syndrome, hemophagocytic lymphohistiocytosis, and myasthenia gravis.Conclusion: Our systematic review indicated the potential of the COVID-19 virus to trigger a myriad of autoimmune and rheumatic manifestations, which should be considered amid global efforts to combat COVID-19.
