Introduction: Studies have described the changing landscape of patients with constrictive pericarditis (CP) in the modern era, however no systematic review or meta-analysis has been performed. Methods: We systematically searched the MEDLINE, Embase and Cochrane databases from their inception to April 1, 2020 for studies assessing the characteristics and outcomes patients with CP undergoing pericardiectomy. A meta-analysis was performed to assess the impact of CP etiology on outcomes. Results: We analyzed 27 eligible studies and 2114 patients. Etiology was most commonly idiopathic (50.2%), post-cardiac surgery (26.2%) and radiation (6.9%)(Figure 1A-B). Patients were mostly men (76%), with a mean age of 58 years and with advanced symptoms (NYHA III/IV 70.1%). Total pericardiectomy was preferred (85.8%) (Figure 1C-D) and concomitant cardiac surgery was relatively common (23.8%). Operative mortality was 6.9% and 5-year mortality was 32.7% (Table 1). Radiation and post-cardiac surgery patients had higher long-term risk for mortality respectively compared to idiopathic pericarditis (HR: 2.15; 95% CI: 1.21-1.36, p=.01 and HR: 3.21; 95% CI: 1.56-6.50, p<.01, respectively). Thirty percent of included studies had more than low bias. A sensitivity analysis did not result in changes in the results. Conclusions: Pericardiectomy is performed mostly in middle-aged men with advanced symptoms and low comorbidity burden and still carries a significant operative mortality. Radiation and post-cardiac surgery patients have a significantly higher risk compared to idiopathic. Several methodological issues and significant heterogeneity limit the generalization of these data.

AbstractBackgroundA year following the onset of the COVID-19 pandemic, new infections and deaths continue to increase in Europe. Serological studies, through providing evidence of past infection, can aid understanding of the population dynamics of SARS-CoV-2 infection.ObjectivesThis systematic review of SARS-CoV-2 seroprevalence studies in Europe was undertaken to inform public health strategies including vaccination, that aim to accelerate population immunity.MethodsWe searched the databases Web of Science, MEDLINE, EMBASE, SCOPUS, Cochrane Database of Systematic Reviews and grey literature sources for studies reporting seroprevalence of SARS-CoV-2 antibodies in Europe published between 01/12/2019 - 30/09/20. We provide a narrative synthesis of included studies. Studies were categorized into subgroups including healthcare workers (HCWs), community, outbreaks, pregnancy and children/school. Due to heterogeneity in other subgroups, we only performed a random effects meta-analysis of the seroprevalence amongst HCWs stratified by their country.Results109 studies were included spanning 17 European countries, that estimated the seroprevalence of SAR-CoV2 from samples obtained between November 2019 – August 2020. A total of 53/109 studies included HCWs with a reported seroprevalence among HCWs ranging from 0.7% to 45.3%, which did not differ significantly by country. In community studies significant heterogeneity was reported in the seroprevalence among different age groups and the majority of studies reported there was no significant difference by gender.ConclusionThis review demonstrates a wide heterogeneity in reported seroprevalence of SARS-CoV-2 antibodies between populations. Continued evaluation of seroprevalence is required to understand the impact of public health measures and inform interventions including vaccination programmes.

UNSTRUCTURED A systematic review will be carried out to examine the use of robots in early childhood and lower-level education, elder care, and learning/teaching in an educational institution(s). Present study to critically review the currently available evidence of studies carried out and look at the impact of humanoid robots on children, elder care, and education. Four major factors will be considered – the type of studies carried on the influence of robots on children’s behavior and growth, elder care, the understanding of stakeholders (parents, children, and educators) on educational robots, and finally, the reactions of the children and elderly population on robot design or presence. This review will reveal the validating of their use of robots including experimental and non-experimental trials. The steps in this process will be conducted according to the PRISMA-P (Preferred Reporting Items for Systematic reviews and Meta-Analysis Protocols) guidelines for meta-analysis. A comprehensive review of the literature search from Medline, the Cochrane Library, Scopus, PubMed, ProQuest, and secondary references will be performed from inception to April 15, 2021. Analyses will be done to calculate summary estimates on awareness indicators and test procedures by using fixed/random-effects models. Meta-regression and covariate analyses will be performed to explore the influence of confounders on the net pooled effect. Titles and abstracts will be assessed by three independent reviewers for potential relevance. Using study-specific data forms, predetermined data will be extracted for each study. Data extracted will include: 1) study characteristics, 2) study design, 3) population characteristics, 4) details of the comparison group(s), 5) awareness indicators, 6) skills development, 7) progressive, 8) outcome data, and 9) Study year. Other classifications to be considered are a type of skill and specific age.

Introduction: The use of cardiopulmonary bypass in pediatric cardiac surgery is associated with significant inflammation, fluid overload, and end-organ dysfunction yielding morbidity and mortality. For decades, various intraoperative ultrafiltration techniques such as conventional ultrafiltration, modified ultrafiltration (MUF), zero-balance ultrafiltration (ZBUF), and combination techniques (ZBUF-MUF) have been used to mitigate these toxicities and promote improved postoperative outcomes. However, there is currently no consensus on the ultrafiltration technique or strategy that yields the most benefit for infants and children undergoing open heart surgery. Methods: A librarian-conducted PubMed literature search from 1990 to 2018 yielded 90 clinical studies or publications on the various forms of ultrafiltration and the impact on physiologic markers and clinical outcomes. All publications were reviewed, summarized, and conclusions synthesized. The data sets were not combined for systematic or meta-analysis due to significant heterogeneity in study protocols and patient populations. Results: Modified ultrafiltration significantly promotes improved myocardial function, reduction in fluid overload, and reduced bleeding and transfusion complications. Furthermore, ZBUF has shown a consistent reduction in inflammatory cytokines and improved pulmonary function and compliance. There is conflicting evidence that MUF, ZBUF, and ZBUF-MUF culminate in reduced ventilation time and intensive care unit stay. Conclusion: Various modes of ultrafiltration have been shown to be associated with improved physiologic function or clinical outcomes in pediatric cardiac surgery. There are some inconsistent trial results that can be explained by heterogeneity in ultrafiltration, clinical staff preferences, and institution protocols. Ultrafiltration has some essential benefit as it is ubiquitously used at pediatric heart centers; however, the optimal protocol could be yet identified.

Abstract Background and Aims Interest in histology for ulcerative colitis [UC] has increased recently. This systematic review and meta-analysis aims to assess, for the first time, whether histological outcomes are more informative than endoscopic and clinical outcomes in distinguishing the impact of intervention over placebo in induction trials. Methods MEDLINE, ScienceDirect and Cochrane Central Register of Controlled Trials were searched to identify randomized placebo-controlled trials [RCTs] enrolling moderate-to-severe UC patients. Studies were assessed using the Quality Assessment Tool for Studies with Diverse Designs. We analysed the pooled proportion of patients achieving clinical, endoscopic and histological remission and response after a pharmacological intervention and compared the results with those of placebo-treated patients by using a random-effects model. Results From 889 identified records, 13 RCTs were included. The odds ratio [OR] for remission was higher in patients receiving intervention than in those under placebo for clinical (OR 2.13, 95% confidence interval [CI] 1.33–3.43), endoscopic [OR 1.46, 95% CI 0.19–11.18] and histological remission [OR 1.85, 95% CI 1.20–2.84]. Significant differences were observed for all response outcomes [clinical: OR 2.27, 95% CI 1.84–2.85; endoscopic: OR 2.16, 95% CI 1.51–3.10; histological: OR 3.63, 95% CI, 1.41–9.36]. No significant heterogeneity existed; no subgroup effects were found for duration of the induction or histological scale [p &gt; 0.05]. Clinical and histological remission and endoscopic response were concordant in discriminating interventions from placebo. Conclusion Histological outcomes are informative in trials of moderate-to-severe UC. Further studies analysing histology at the end of induction are needed to confirm its relevance in distinguishing the efficacy of an intervention over placebo in comparison to clinical and endoscopic outcomes and to explore its prognostic value.

The Relationship

364 Background: The optimal timing from CRC surgery to initiation of AC is unknown. We report a systematic review and meta-analysis to determine the relationship between time to adjuvant chemotherapy (TTAC) and survival. Methods: A systematic review of literature was done to identify studies that described the relationship between TTAC and survival. Studies were only included if the distribution of relevant prognostic factors was adequately described, and either comparative groups were balanced or results adjusted for the prognostic factors. Hazard ratio (HR) and TTAC for overall survival (OS) and disease free survival (DFS) from each study were converted to a regression coefficient (β) and standard error (SE) corresponding to a continuous representation per 4 weeks of TTAC. The adjusted β from individual studies were combined using a fixed-effect model. Inverse-variance (1/SE2) was used to weight individual studies. The possible effect of publication bias was investigated using the trim and fill approach. Results: We identified 9 eligible studies involving 14,357 patients (4 published articles, 5 abstracts). Two studies were randomized trials and 7 were cohort studies. Six studies reported TTAC as a binary variable and 3 reported TTAC as ≥3 categories. An estimate of HR for OS was derived from all 9 studies and estimate for DFS was derived from 5 studies. Meta-analysis demonstrated that a 4-week increase in TTAC was associated with a significant decrease in both OS (HR = 1.12, 95% CI 1.09-1.15), and DFS (HR = 1.15, 95% CI 1.11-1.20). The analysis showed no significant heterogeneity among studies. These TTAC associations remained significant after analysis for potential publication bias, and when the analysis was repeated excluding the two studies of largest weight. Conclusions: This study demonstrates a 12% increase in the risk of death for each 4 week of delay in the start of AC for CRC. These findings indicate the need for clinicians and health systems managers to take the steps necessary to keep TTAC as short as reasonably achievable. In addition, our results suggest there may be some benefit to AC after a 3-month TTAC delay. No significant financial relationships to disclose.

150 Background: Nearly 50% of men diagnosed with prostate cancer may receive treatment with some form of androgen deprivation therapy (ADT). While some side effects of ADT are well acknowledged, the specific impact of ADT on cognitive function is uncertain. Our objective was to perform a systematic review and meta-analysis assessing the impact of ADT on overall cognitive decline, and the risks of Alzheimers, Parkinson’s disease. Methods: Relevant studies were identified through search of English language articles indexed in PubMed Medline, PsycINFO, Cochrane Library and Web of Knowledge/Science. First, we assessed rates of cognitive decline in five cohorts from three studies. Second, we assessed rates of Alzheimer’s or Parkinson disease using three large retrospective studies. A pooled-analysis was conducted using a meta-analysis. Weighted averages were reported as odds ratios (OR) with 95% confidence intervals (CI) using RevMan and a DerSimonian and Laird random-effects model. The heterogeneity test was measured using the Q-Mantel-Haenszel ( P< 0.10 was considered of significant heterogeneity). Results: With respect to overall cognitive decline (defined as scoring 1.5 standard deviations [SD] in two or more objective cognitive tests), patients receiving ADT had higher odds of overall cognitive decline than patients with prostate cancer not treated with ADT or health controls (OR: 2.03, 95% CI: 1.42–2.90). Furthermore, men with a history of ADT for prostate cancer had higher odds of developing Alzheimer’s and Parkinson dementia compared to men with prostate cancer not treated with ADT (OR: 1.32, 95% CI: 1.27–1.37). Conclusions: Men receiving ADT for prostate cancer performed significantly worse on measures of overall cognitive function. Additionally, results from the three large observational trials included suggest men exposed to ADT for prostate cancer have higher rates of Parkinson/Alzheimer’s compared to men without ADT.

Objective Conduct a systematic review and meta-analysis to estimate the impact of pharmacy-supported interventions on the proportion of patients discharged from the hospital on inappropriate acid suppressive therapy (AST). Methods To identify studies, the following databases were systematically searched on October 14th, 2018 and repeated on September 12th, 2019: Ovid MEDLINE(R) and In-Process & Other Non-Indexed Citations and Daily, Embase.com, CINAHL, Web of Science, Cochrane CENTRAL (EBSCO), and ClinicalTrials.gov. Eligible studies consisted of adults, intervention and historical/usual care groups, description of active pharmacy-supported intervention, and proportion of patients discharged on inappropriate AST. Qualitative assessments and quantitative analyses were performed. Modified funnel plot analysis assessed heterogeneity. Preferred reporting items of systematic reviews and meta-analyses (PRISMA) methodology was used to evaluate studies in this review. Results Seventeen publications resulting in 16 studies were included in the review. Using random effects model, meta-analysis showed a significant reduction in the odds of being discharged on inappropriate AST from the hospital in the pharmacist-supported intervention arm versus comparator (Odds Ratio 0.33 [95%CI 0.20 to 0.53]), with significant heterogeneity (I2 = 86%). Eleven studies favored pharmacy-supported interventions, four were inconclusive and one favored usual care. Using modified funnel plot analysis, our final evaluation was distilled to 11 studies and revealed a similar outcome (OR 0.36 [95%CI 0.27 to 0.48]), but with less heterogeneity (I2 = 36%). Conclusion This systematic review and meta-analysis showed that pharmacy-supported interventions were associated with a significantly reduced probability of patients discharged on inappropriate AST. However, heterogeneity was high and may affect interpretation of results. Using funnel plot optimization method, three positive and two negative studies were objectively removed from analyses, resulting in a similar effect size, but with less heterogeneity. To improve study quality, future researchers should consider utilizing a pre-post, multi-arm, prospective design with sampling randomization, training of data extractors (preferably two extractors), re-evaluating a small dataset to check for agreement and providing a comprehensive methodology in subsequent publications.

The Impact

Telehealth interventions have the opportunity to scale evidenced-based therapeutics and increase service access to historically hard to reach populations, including rural, and minority groups. Behavior management parenting interventions are a best-practice intervention to treat a range of disruptive behavior disorders and family dysfunction concerns, which have traditionally occurred in person, but recently been trialed online due to growing demand and a need for remote delivery during COVID-19. There is limited and mixed information to date regarding evidence for online services and minimal research on client and therapeutic factors associated with better outcomes, which is critical for advancing efficacy in the rapidly-growing approach to treating child mental illness. Therefore, we conducted a systematic review and meta-analysis (k = 24, total number of intervention participants = 1469 and control participants = 800) of the impact of digital parent training interventions on parent skill, parent mental health, and child externalizing mental health outcomes from 2000 to 2020, among children 2-12 years old, across four databases. Exclusionary criteria include programs targeted for parents of children with intellectual disabilities, autism, brain injury, nutrition/health/dental needs or primary medical diagnosis. Across outcomes, there was a modest effect size of digital parent training interventions (g =.22-.30), compared to controls using random effect two-level and multi-level models. Study heterogeneity varied across outcomes (I² = 18.6% to 66.3%). Results of publication bias were mixed across tests, but they were suggestive of a slight inflation of the effects sizes across outcomes. We tested several moderators related to child demographics, family socioeconomic status, intervention design, and risk of bias. We found the effects of digital parent training on parent skills and child outcomes were stronger if the intervention used was evidence-based, combined hybrid interactive platforms with a therapist and was compared to an inactive control. Given the limitations from the existing literature assess moderating effects regarding population characteristics (i.e. SES, parent mental health), we call on future studies to provide standardized demographics to aide future knowledge synthesis work and provide templates for shared measurement. We preregistered our meta-analysis here, with datafile, code and supplementary: https://osf.io/e35bt/.
