PCAD possesses a public health challenge resulting in years of productive life lost and an escalating burden on health systems. Objective of this review is to compare modifiable and non-modifiable risk factors for PCAD compared to those without PCAD. This review will include all comparative observational studies conducted in adults aged >18 years with confirmed diagnosis of PCAD (on angiography) compared to those without PCAD. Databases to be searched include; PubMed, CINAHL, Embase, Web of Science, and grey literature (Google Scholar). All identified studies will be screened for title and abstract and full-text against the inclusion criteria on Covidence software. Data relevant to exposures and outcomes will be extracted from all included studies. All studies selected for data extraction will be critically appraised for methodological quality. Meta-analysis using random-effects model will be performed using Review Manager 5.3. Effect sizes for categorical risk factors will be expressed as odds ratios with 95% confidence intervals. For risk factors measured in continuous form, mean difference (if units are consistent) otherwise standardized mean difference (if units are different across studies) will be reported. Heterogeneity between studies will be assessed using I2 test statistics. GRADE will be used to assess the certainty of the findings.

IntroductionThe need for organs is comparatively higher among people of Indian origin due to the higher prevalence of end-stage organ failure. In spite of the higher need, they have a lower number of organ donors. Studies have been carried out among people of Indian origin living globally to understand the reasons for the low donation rate, but there has been no systematic review that has integrated all of these studies to synthesise the current literature. Therefore, the purpose of this review is to examine the barriers towards organ donor registration and consent among Indians living globally.Methods and analysisA systematic search will be conducted using the following relevant databases namely CINHAL, MEDLINE, PsycINFO, Scopus, Web of Science, PubMed Central, Global Health and Grey literature. Studies from 1994 that satisfy our inclusion criteria will be included. Two reviewers will conduct the screening, data extraction and quality assessment of the studies; in event of any disagreement between the two reviewers at any stage, the third reviewer will reconcile any disagreements and consensus will be made.Ethics and disseminationAs this study includes only secondary data, ethical approval for secondary data usage has been sought. This study will use Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines to report and the study outcomes will be disseminated through a relevant peer-review publication, related conferences and also to various non-governmental organisations globally which are working with this particular community; following which further research can be developed based on this evidence and also helps in building a culturally competent strategy.PROSPERO registration numberCRD42019155274.

Abstract BackgroundAtrial Fibrillation (AF) is the most frequent cardiac arrhythmia and it is associated with life-threatening complications such as hemodynamic instability and thromboembolic events. Electrical cardioversion remains its mainstay of treatment and can be performed either urgently or electively. Relapse after electrical cardioversion has been reported by several primary studies with divergent results, but no detailed summary exists for a critical appraisal of its global incidence and risk factors.Therefore, we propose the first systematic review and meta-analysis to synthesize the existing data on the global incidence and risk factors of relapse after electrical cardioversion for AF.MethodsWe will include case-control and cohort studies reporting on the incidence and risk factors of relapse after electrical cardioversion for atrial fibrillation. Electronic databases including PubMed, Embase, WHO Global Health Library and Web of Science will be searched for relevant records published between January 01, 2000, and December 15, 2020. Pairs of independents reviewers will perform study selection and data extraction, as well as an assessment of the methodological quality of included studies. Appropriate meta-analysis will then be used to pool studies judged to be clinically homogenous. Egger’s test and funnel plots will be used to detect publication bias. Findings will be reported and compared by the human development level of countries. ResultsThis systematic review and meta-analysis to synthesize the existing data on the global incidence and risk factors of relapse after electrical cardioversion for AFConclusionThis review is expected to provide relevant data to help in evaluating the burden and risk factors of relapse after electrical cardioversion for atrial fibrillation. The overall findings of this research will be published in a peer-reviewed journal.

Review Protocol

ObjectiveThis living systematic review aims to provide a timely, rigorous and continuously updated summary of the evidence available on the role of macrolides for the treatment of patients with COVID-19.Data sources We will conduct searches in PubMed/Medline, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), grey literature and in a centralised repository in L·OVE (Living OVerview of Evidence). L·OVE is a platform that maps PICO questions to evidence from Epistemonikos database. In response to the COVID-19 emergency, L·OVE was adapted to expand the range of evidence it covers and customised to group all COVID-19 evidence in one place. The search will cover the period until the day before submission to a journal.Eligibility criteria for selecting studies and methods We adapted an already published common protocol for multiple parallel systematic reviews to the specificities of this question. We will include randomised trials evaluating the effect of macrolides — as monotherapy or in combination with other drugs — versus placebo or no treatment in patients with COVID-19. Randomised trials evaluating macrolides in infections caused by other coronaviruses, such as MERS-CoV and SARS-CoV, and non-randomised studies in COVID-19 will be searched in case we find no direct evidence from randomised trials, or if the direct evidence provides low- or very low-certainty for critical outcomes.Two reviewers will independently screen each study for eligibility, extract data, and assess the risk of bias. We will pool the results using meta-analysis and will apply the GRADE system to assess the certainty of the evidence for each outcome. A living, web-based version of this review will be openly available during the COVID-19 pandemic. We will resubmit it every time the conclusions change or whenever there are substantial updates.Ethics and dissemination No ethics approval is considered necessary. The results of this review will be widely disseminated via peer-reviewed publications, social networks and traditional media.PROSPERO Registration number CRD42020181032

Review Protocol

IntroductionOwing to their propensity for being associated with infections, biofilms have become a focus in infectious disease research. There is evidence suggesting that statins, which are commonly used for prevention of cardiovascular disease, may prevent biofilm-associated infections, but this association has not been well-understood.Methods and analysisThis systematic review protocol will include six database searches from their inception to 20 August 2020. A medical librarian will conduct the searches in PubMed, EMBASE, Web of Science, CINAHL, LILACS and CENTRAL, without any limits. Bibliographies of selected articles, previously published reviews and high-yield journals that publish on statins and/or biofilms will be searched to identify additional articles. The screening and data extraction will be conducted by two independent reviewers using DistillerSR. All included papers will also be evaluated for quality using Cochrane Risk of Bias Assessment tool, and we will examine for publication bias. If there are two or more studies with quantitative estimates that can be combined, we will conduct a meta-analysis after assessing for heterogeneity. We will report all findings according to the Preferred Reporting Items for Systematic reviews and Analyses-P framework.Ethics and disseminationThere are conflicting results on the effect of statins on biofilm-associated infections. The rise of antibiotic resistance in medical settings warrants a deeper understanding of this association, especially if statins can be used as a novel antibiotic. The findings of this review will assess the association between statin use and biofilm-associated infection to inform future medical practice. No formal ethical review is required for this protocol. All findings will be published in a peer-reviewed journal.PROSPERO registration numberCRD42020193985.

The Impact

IntroductionThere is a growing concern about the misuse of over the counter (OTC) and prescription only medication (POM) because of the impact on physical and mental health, drug interactions, overdoses and drug-related deaths. These medicines include opioid analgesics, anxiolytics such as pregabalin and diazepam and antidepressants. This protocol outlines how a systematic review will be undertaken (during June 2021), which aims to examine the literature on the pattern of OTC and POM misuse among adults who are accessing substance misuse treatment services. It will include the types of medication being taken, prevalence and demographic characteristics of people who access treatment services.Methods and analysisAn electronic search will be conducted on the Cochrane, OVID Medline, Pubmed, Scopus and Web of Science databases as well as grey literature. Two independent reviewers will conduct the initial title and abstract screenings, using predetermined criteria for inclusion and exclusion. If selected for inclusion, full-text data extraction will be conducted using a pilot-tested data extraction form. A third reviewer will resolve disagreements if consensus cannot be reached. Quality and risk of bias assessment will be conducted for all included studies. A qualitative synthesis and summary of the data will be provided. If possible, a meta-analysis with heterogeneity calculation will be conducted; otherwise, Synthesis Without Meta-analysis will be undertaken for quantitative data. The reporting of this protocol follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses.Ethics and disseminationEthical approval is not required. Findings will be peer reviewed, published and shared verbally, electronically and in print, with interested clinicians and policymakers.PROSPERO registration numberCRD42020135216.

IntroductionIndividuals living in poor neighbourhoods are at a higher risk of overweight/obesity. There is no systematic review and meta-analysis study on the association of neighbourhood socioeconomic status (NSES) with overweight/obesity. We aimed to systematically review and meta-analyse the existing evidence on the association of NSES with overweight/obesity.Methods and analysisCross-sectional, case–control and cohort studies published in English from inception to 15 May 2017 will be systematically searched using the following databases: PubMed, EMBASE, Web of Sciences and Google Scholar. Selection, screening, reviewing and data extraction will be done by two reviewers, independently and in duplicate. The Newcastle–Ottawa Scale (NOS) will be used to assess the quality of evidence. Publication bias will be checked by visual inspection of funnel plots and Egger’s regression test. Heterogeneity will be checked by Higgins’s method (I2statistics). Meta-analysis will be done to estimate the pooled OR. Narrative synthesis will be performed if meta-analysis is not feasible due to high heterogeneity of studies.Ethics and disseminationEthical clearance is not required as we will be using data from published articles. Findings will be communicated through a publication in a peer-reviewed journal and presentations at professional conferences.PROSPERO registration numberCRD42017063889.

Introduction: Patients with multimorbidity are expected to adhere to complex medication regimens in order to manage their multiple chronic conditions. It has been reported the likelihood of adherence decreases as patients are prescribed more medications. Much medication adherence research to date is dominated by a single-disease focus, which is at odds with the rising prevalence of multimorbidity and may artificially underestimate the complexity of managing chronic illness. This review aims to describe the prevalence of medication non-adherence among patients with multimorbidity, and to identify potential predictors of non-adherence in this population. Methods: A systematic review will be conducted and reported according to PRISMA guidelines. PubMed, EMBASE, CINAHL and PsycINFO will be searched using a predefined search strategy from 2009–2019. Quantitative studies will be considered eligible for review if prevalence of medication non-adherence among adults with two or more chronic conditions is reported. Studies will be included in the review if available in English full text. Titles and abstracts will be screened by single review, with 20% of screening cross-checked by a second reviewer. Full-text articles will be screened by two independent reviewers, noting reasons for exclusions. Data extraction will be performed using a predefined extraction form. Quality and risk of bias assessment will be conducted using criteria for observational studies outlined by Sanderson et al. (2007). A narrative synthesis and, if feasible, meta-analysis will be conducted. Discussion: By exploring medication non-adherence from a multimorbidity perspective, the review aims to inform an evidence base for intervention development which accounts for the rising prevalence of patients with multiple chronic conditions.  Study registration: The systematic review is prospectively registered in PROSPERO (CRD42019133849); registered on 12 June 2019.

UNSTRUCTURED The objective of this systematic review is to determine the effect of genetic variants that associate with antidiabetic medications and their efficacy and toxicity in T2DM patients. The understanding may allow interventions for improving management of T2DM and later systematically evaluated in more in-depth studies. We will have performed a comprehensive search using PubMed, Scopus, EMBASE, Web of Sciences and Cochrane database from 1990 to 2018. Relevant journals and references of all included studies will be hand searched to find the additional studied. Eligible studies such as pharmacogenetics studies in terms of drug response and toxicity in the type 2 diabetes patients and performed just on human will be included. Data extraction and quality assessment will be carried out by two independent reviewers and disagreements will be resolved through third expert reviewer. Risk of bias will be assessed with the Cochrane Risk of Bias tool for randomized studies and Newcastle-Ottawa Scale (NOS) for observational Studies. Narrative synthesis will be conducted by the combination of key findings. The results of this study will be submitted to a peer-reviewed journal for publication and also presented at PROSPERO. We expect this review will provide highly relevant information for clinicians, pharmaceutical industry that will benefit from the summary of the best available data regarding the efficacy of antidiabetic medication in the aspect of pharmacogenetics.

Pooled Prevalence

Background A number of primary studies in Ethiopia address the prevalence of birth asphyxia and the factors associated with it. However, variations were seen among those studies. The main aim of this systematic review and meta-analysis was carried out to estimate the pooled prevalence and explore the factors that contribute to birth asphyxia in Ethiopia. Methods Different search engines were used to search online databases. The databases include PubMed, HINARI, Cochrane Library and Google Scholar. Relevant grey literature was obtained through online searches. The funnel plot and Egger’s regression test were used to see publication bias, and the I-squared was applied to check the heterogeneity of the studies. Cross-sectional, case-control and cohort studies that were conducted in Ethiopia were also be included. The Joanna Briggs Institute checklist was used to assess the quality of the studies and was included in this systematic review. Data entry and statistical analysis were carried out using RevMan 5.4 software and Stata 14. Result After reviewing 1,125 studies, 26 studies fulfilling the inclusion criteria were included in the meta-analysis. The pooled prevalence of birth asphyxia in Ethiopia was 19.3%. In the Ethiopian context, the following risk factors were identified: Antepartum hemorrhage(OR: 4.7; 95% CI: 3.5, 6.1), premature rupture of membrane(OR: 4.0; 95% CI: 12.4, 6.6), primiparas(OR: 2.8; 95% CI: 1.9, 4.1), prolonged labor(OR: 4.2; 95% CI: 2.8, 6.6), maternal anaemia(OR: 5.1; 95% CI: 2.59, 9.94), low birth weight(OR = 5.6; 95%CI: 4.7,6.7), meconium stained amniotic fluid(OR: 5.6; 95% CI: 4.1, 7.5), abnormal presentation(OR = 5.7; 95% CI: 3.8, 8.3), preterm birth(OR = 4.1; 95% CI: 2.9, 5.8), residing in a rural area (OR: 2.7; 95% CI: 2.0, 3.5), caesarean delivery(OR = 4.4; 95% CI:3.1, 6.2), operative vaginal delivery(OR: 4.9; 95% CI: 3.5, 6.7), preeclampsia(OR = 3.9; 95% CI: 2.1, 7.4), tight nuchal cord OR: 3.43; 95% CI: 2.1, 5.6), chronic hypertension(OR = 2.5; 95% CI: 1.7, 3.8), and unable to write and read (OR = 4.2;95%CI: 1.7, 10.6). Conclusion According to the findings of this study, birth asphyxia is an unresolved public health problem in the Ethiopia. Therefore, the concerned body needs to pay attention to the above risk factors in order to decrease the country’s birth asphyxia.
