Abstract Abstract 3993 Poster Board III-929 Background The incidence of stroke in children is estimated at about 2.6 per 100,000 per year. Risk factors include congenital heart malformations, trauma, hemolytic anemias, collagen tissue diseases, inborn metabolic disorders, and infectious diseases. Apart from acquired thrombophilic risk factors, such as the presence of antiphospholipid antibodies, inherited thrombophilias (IT) have been found to be associated with stroke in infants and children. However, results of single studies on the risk of stroke onset associated with IT have been contradictory or inconclusive, mainly due to lack of statistical power. The aim of this study was to estimate the impact of thrombophilia (IT) on risk of childhood stroke via meta-analysis of published observational studies. Methods and Results A systematic search of electronic databases (Medline, EMBASE, OVID, Web of Science, The Cochrane Library) for studies published from 1970 to 2009 was conducted using key words in combination both as MeSH terms and text words. Citations were independently screened by two authors and those meeting the a priori defined inclusion criteria were retained. Data on year of publication, study design, country of origin, number of patients/controls, ethnicity, stroke type (arterial ischemic stroke [AIS]; cerebral venous sinus thrombosis [CSVT]) were abstracted. Publication bias indicator and heterogeneity across studies were evaluated, and summary odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using both fixed-effects and random-effects models. Twenty-one of 185 references found met inclusion criteria. 1698 patients (AIS: 1291; CSVT: 407) and 2913 controls aged neonate to 18 years were enrolled. No significant heterogeneity was discerned across studies, and no publication bias was detected. A statistically significant association with stroke onset was demonstrated for each IT trait evaluated, with no difference found between AIS (table) and CSVT. Summary ORs/CIs (random-effects model) for AIS & CSVT cohorts were as follows: Protein C-deficiency (8.76/4.53-16.96), FV G1691A (3.34/2.66-4.26), FII G20210A (2.50/1.67-3.74), MTHFR T677T (1.61/1.21-2.14), antiphospholipid antibodies (5.84/3.06-11.18), elevated lipoprotein (a) (6.24/4.51-8.64), and combined ITs (8.85/3.32-23.57). Carrier rates reported for antithrombin- or protein S deficiency among patients were 1.5% and 1.6% as compared with 0.06% (p<0.001) and 0.4% (p=0.003) in healthy controls. Conclusions The present meta-analysis indicates that IT serve as risk factors for incident stroke. However, the impact of IT upon outcome and recurrence risk needs to be further investigated.

Based Medicine

Systematic reviews are considered as the highest rung in the ladder of evidence-based medicine. They are bound by a pre-defined structure and requirement for extensive literature searches, when compared with the more liberal format of narrative reviews. Systematic review protocols should ideally be pre-registered to avoid duplication or redundancy. After defining clear review question(s), thorough literature searches form the basis of systematic reviews. Presentation of results should be qualitative or quantitative (meta-analysis) if the data is homogenous enough to permit pooling across multiple studies. Quality of individual studies by Cochrane risk of bias 2 tool for interventional studies and other suitable scales for observational studies, as well as appropriate assessment of publication bias are recommended. Certainty of outcomes should be assessed by the GRADE profiler. Finally, systematic reviews should conclude with recommendations for future research, based on their findings.

Abstract Purpose Clinicians need to know whether inguinal hernia (IH) can be attributed to work to answer questions regarding prevention and medical causation. This review describes whether work-related risk factors are associated with IH. Methods A systematic review was performed in Medline via PubMed until February 3rd, 2020. Inclusion criteria were that IH was diagnosed by a clinician, and workers exposed to work-related risk factors were compared to workers less exposed or not at all. A quality assessment and a meta-analysis using Cochrane’s RevMan 5.3 were performed, including GRADE for quality of evidence. Results The search resulted in 540 references. Fourteen studies fulfilled the inclusion criteria, of which three were included in a meta-analysis, all three being of high quality, including 621 workers diagnosed with IH. The meta-analysis revealed significant associations with physically demanding work (OR 2.30, 95% CI 1.56–3.40). Two prospective studies, including 382 and 22,926 cases revealed associations that this was true for male workers with a lateral IH that reported standing or walking for more than six hours per workday (OR 1.45, 95% CI 1.12–1.88) or lifting cumulative loads of more than 4000 kg per workday (OR 1.32, 95% CI 1.27–1.38). The level of certainty for the latter two work-related risk factors was moderate and high according to GRADE. Conclusion Lateral IH among males is associated with work-related risk factors depending on the level of exposure to the time standing/walking per workday, or the amount of load lifted per workday.

IntroductionThe present study was to explore the correlation between cough variant asthma (CVA) and repeated episodes of mycoplasma pneumonia in children.Material and methodsMultiple databases were searched for relevant studies, and the articles that eventually satisfied the inclusion criteria were included. All the meta-analyses were conducted with the Review Manager 5.2. To estimate the quality of each article, the risk of bias table was performed. Totally 1223 patients with CVA and 1437 patients with simple cough (SC) were included.ResultsFinally, 9 studies including 2660 patients were included, who eventually satisfied the eligibility criteria. The results of heterogeneity test suggested that the serum level of IgE (MD = 80.69, 95%CI [77.75, 83.62], P < 0.001; P for heterogeneity <0.001, I2 = 95%), eosinophil count (MD= 2.93, 95%CI [2.72, 3.13], P < 0.001; P for heterogeneity < 0.001, I2 = 71%) and the number of children with positive IgM (OR = 4.44, 95%CI [3.73, 5.29], P < 0.001; P for heterogeneity = 0.63, I2 = 0%) were significantly different. The value of IgE in CVA was higher than that in SC, eosinophil count in CVA was higher than that in SC and the number of IgM positive children in the CVA group was higher than that in the SC group.ConclusionsThis study demonstrated a correlation between cough variant asthma and mycoplasma pneumonia.

The Right

Background: The concept of evaluating bioequivalence has changed over a period of time. Currently, the Average Bioequivalence approach (ABE) is the gold standard tool for the evaluation of generics. Of late, many debates had arisen about employing ABE approach for the appraisal of all drug categories. This review aims to examine the limitations of ABE approach and the significances of Population Bioequivalence (PBE) and Individual Bioequivalence (IBE) approach, current regulatory thinking for assessing different categories of the drug, whether they are adequately assessed, and the evaluation is in the right direction. Methods: We carried out an organized search of bibliographic databases for peer-reviewed research literatures, regulatory recommendations, guidance documents using a focused review question and eligibility criteria. The standard tools were used to appraise the quality of retrieved documents and to make sure the authenticity of the data. Results: In total 73 references were used in the review, the majority of the references (guidance documents) were from the different regulatory agencies and product-specific guidance. There were 29 product-specific guidance from USFDA and EMA. The limitations of the ABE approach were discussed in detail along with the significances of Population Bioequivalence (PBE) approach and Individual Bioequivalence (IBE) approaches. Conclusion: It is apparent from the review that IBE approach is a precise method for evaluating the drugs as it answers drug interchangeability (prescribability and switchability). IBE approach is followed by PBE approach and ABE approach for the evaluation of different categories of drugs in terms of precision.

BACKGROUND Anxiety and depression rates are at an all-time high along with other mental health disorders. Smartphone-based mental health chatbots or conversational agents can aid psychiatrists and replace some of the costly human based interaction and represent a unique opportunity to expand the availability and quality of mental health services and treatment. Regular up-to-date reviews will allow medics and individuals to recommend or use anxiety and depression related smartphone based chatbots with greater confidence. OBJECTIVE Assess the quality and characteristics of chatbots for anxiety and depression available on Android and iOS systems. METHODS A search was performed in the App Store and Google Play Store following the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) protocol to identify existing chatbots for anxiety and depression. Eligibility of the chatbots was assessed by two individuals based on predefined eligibility criteria. Meta-data of the included chatbots and their characteristics were extracted from their description and upon installation by 2 reviewers. Finally, chatbots quality information was assessed by following the mHONcode principles. RESULTS Although around 1000 anxiety and depression related chatbots exist, only a few (n=11) contained actual chatbots that could provide the user a real substitute for a human-human based interaction, even with today's Artificial Intelligence advancements, only one of these chatbots had voice as an input/output modality. Of the selected apps that contained chatbots all were clearly built with a therapeutic human substitute goal in mind. The majority had high user ratings and downloads highlighting the popularity of such chatbots and their promising future within the realm of anxiety and depression. CONCLUSIONS Anxiety and depression chatbot apps have the potential to increase the capacity of mental health self-care providing much needed assistance to professionals. In the current covid-19 pandemic, chatbots can also serve as a conversational companion with the potential of combating loneliness, especially in lockdowns where there is a lack of social interaction. Due to the ubiquitous nature of chatbots users can access them on-demand at the touch of a screen on ones’ smartphone. Self-care interventions are known to be effective and exist in various forms and some can be made available as chatbot features, such as assessment, mood tracking, medicine tracking, or simply providing conversation in times of loneliness.

Beta Blocker Therapy

Abstract Background Beta-blockers are associated with reduced mortality in patients with cardiovascular disease but are often under prescribed in those with concomitant COPD, due to concerns regarding respiratory side-effects. We investigated the effects of beta-blockers on outcomes in patients with COPD and explored within-class differences between different agents. Methods We searched the Cochrane Central Register of Controlled Trials, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Medline for observational studies and randomized controlled trials (RCTs) investigating the effects of beta-blocker exposure versus no exposure or placebo, in patients with COPD, with and without cardiovascular indications. A meta-analysis was performed to assess the association of beta-blocker therapy with acute exacerbations of COPD (AECOPD), and a network meta-analysis was conducted to investigate the effects of individual beta-blockers on FEV1. Mortality, all-cause hospitalization, and quality of life outcomes were narratively synthesized. Results We included 23 observational studies and 14 RCTs. In pooled observational data, beta-blocker therapy was associated with an overall reduced risk of AECOPD versus no therapy (HR 0.77, 95%CI 0.70 to 0.85). Among individual beta-blockers, only propranolol was associated with a relative reduction in FEV1 versus placebo, among 199 patients evaluated in RCTs. Narrative syntheses on mortality, all-cause hospitalization and quality of life outcomes indicated a high degree of heterogeneity in study design and patient characteristics but suggested no detrimental effects of beta-blocker therapy on these outcomes. Conclusion The class effect of beta-blockers remains generally positive in patients with COPD. Reduced rates of AECOPD, mortality, and improved quality of life were identified in observational studies, while propranolol was the only agent associated with a deterioration of lung function in RCTs.

Multiple recurrent somatic mutations have recently been identified in association with myeloproliferative neoplasms (MPN). This meta-analysis aims to assess the pooled prevalence of TET2 gene mutations among patients with MPN. Six databases (PubMed, Scopus, ScienceDirect, Google Scholar, Web of Science and Embase) were searched for relevant studies from inception till September 2020, without language restrictions. The eligibility criteria included BCR-ABL-negative MPN adults with TET2 gene mutations. A random-effects model was used to estimate the pooled prevalence with 95% confidence intervals (CIs). Subgroup analyses explored results among different continents and countries, WHO diagnostic criteria, screening methods and types of MF. Quality assessment was undertaken using the Joanna Briggs Institute critical appraisal tool. The study was registered with PROSPERO (CRD42020212223). Thirty-five studies were included (n = 5121, 47.1% female). Overall, the pooled prevalence of TET2 gene mutations in MPN patients was 15.5% (95% CI: 12.1–19.0%, I2 = 94%). Regional differences explained a substantial amount of heterogeneity. The prevalence of TET2 gene mutations among the three subtypes PV, ET and MF were 16.8%, 9.8% and 15.7%, respectively. The quality of the included studies was determined to be moderate–high among 83% of the included studies. Among patients with BCR-ABL-negative MPN, the overall prevalence of TET2 gene mutations was 15.5%.
