Acute Exacerbations

Abstract Background Chronic obstructive pulmonary disease (COPD) is a major cause of years of life lost globally. Acute exacerbations of COPD (AECOPD) drive disease progression, reduce quality of life and are a source of mortality in COPD. Approximately 50% of AECOPD are due to bacterial infections. Diagnosing bacterial infection as the aetiology of AECOPD however remains challenging as investigations are limited by practicality, accuracy and expense. Clinicians have traditionally used sputum colour as a marker of bacterial infection in AECOPD, despite the lack of high-quality evidence for this practice. The aim of this systematic review and meta-analysis is to determine the diagnostic accuracy of sputum colour in the diagnosis of bacterial causes of AECOPD. Methods Articles will be searched for in electronic databases (MEDLINE, Google Scholar Scopus, Web of Science, Africa-Wide, CINAHL and Health Source Nursing Academy) and we will conduct a review of citation indexes and the grey literature. Two reviewers will independently conduct study selection, against pre-defined eligibility criteria, data extraction and quality assessment of included articles using the QUADAS-2 tool. We will perform a meta‐analysis using a bivariate logistic regression model with random effects. We will explore heterogeneity through the visual examination of the forest plots of sensitivities and specificities and through the inclusion of possible sources of heterogeneity as covariates in a meta-regression model if sufficient studies are included in the analysis. We also perform a sensitivity analysis to explore the effect of study quality on our findings. The results of this review will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement and will be submitted for peer-review and publication. Discussion The findings of this review will assist clinicians in diagnosing the aetiology of AECOPD and may have important implications for decision making in resource-limited settings, as well as for antimicrobial stewardship.

The Status

IntroductionFor a country that lacks a national cervical cancer screening/prevention programme, there is the need to assess the volume of country-specific information, and the status of research on HPV and cervical cancer, in order to provide evidence that will inform policy and further research. The aim of this protocol is to plan an intended systematic review, which is to identify research gaps, prevent unnecessary duplication of work and enable collaboration.Methods and analysisThis protocol, developed according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols statement and registered by PROSPERO (CRD42017075583), will apply a 13-point eligibility criteria to screening and selecting peer-reviewed research articles and grey literature. These will be obtained from searches in databases, including, among others, those of the National Centre for Biotechnology Information, Cochrane Central Register of Controlled Trials, Google Scholar and the digital collections database of research publications of Universities in Ghana. Collected data will be aggregated and summarised according to emerging themes and simple descriptive statistics.Ethics and disseminationThe study will use publicly available data and will not identify authors of the publication by name. In light of these and as has been indicted, research ethics clearance is not required for evidence syntheses in such reviews. The review will be published in peer-reviewed scientific journals and presented at local and internal conferences as the opportunity becomes available.PROSPERO registration numberCRD42017075583.

Objective: The objective of this systematic review is to assess the effectiveness and safety of platelet rich fibrin (PRF) in third molar surgery. Data sources: A comprehensive search strategy is meant to be used in an attempt to identify all relevant RCTs, ongoing investigation reported in specialty congresses and trials regardless of language or publication status (published, unpublished, in press, and in progress). Search will be conducted in The Cochrane Central Register of Controlled Trials (CENTRAL); PUBMED; Embase; Lilacs, and also conduct a search through trial registries of the International Clinical Trials Registry Platform (ICTRP), Word Health Organization (WHO) and the ClinicalTrials.gov, US National Institutes of Health (NIH), grey literature search and specialty congress will be reviewed. Eligibility criteria: We will include randomised trials evaluating the effect of PRF on wound healing after third molar surgery. Two reviewers will independently screen each study for eligibility, extract data, and assess the risk of bias using Cochrane 'risk of bias' tool. We will pool the results using meta-analysis and will apply the GRADE system to assess the certainty of the evidence for each outcome. Ethics and dissemination: As researchers will not access information that could lead to the identification of an individual participant, obtaining ethical approval was waived.

The Impact

ABSTRACTObjectiveTo determine the impact of mesenchymal stromal cells outcomes important to patients with COVID-19.DesignThis is the protocol of a living systematic review.Data sourcesWe 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 methodsWe 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 mesenchymal stromal cells versus placebo or no treatment in patients with COVID-19. Randomised trials evaluating other coronavirus infections, 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 disseminationNo ethics approval is considered necessary. The results of this review will be widely disseminated via peer-reviewed publications, social networks and traditional media.PROSPERO RegistrationSubmitted to PROSPERO (awaiting ID allocation).

Occupational Violence

IntroductionOccupational violence affects several categories of workers; however, the health sector category has been considered at a high risk, exposing workers to physical and psychological abuse. Thus, occupational violence has decreased the quality of care in health service. This review aims to evaluate the effectiveness of interventions for the prevention and reduction of occupational violence against health professionals.Methods and analysisThis protocol is consistent with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. Searches will be conducted in PubMed, Embase, Cochrane Library, LILACS, Web of Science, Scopus, CINAHL and LIVIVO along with a comprehensive review of grey literature. The search will be conducted on August 1 st 2020, without language and time restrictions. Following the eligibility criteria, two independent reviewers will select the titles and abstracts and subsequently screen the full articles. If necessary, a third reviewer will assess any disagreements. All references will be imported into EndNote, and any duplicates will be removed. The data will be extracted using an extraction-based form from Cochrane. Statistical analyses will be performed using the software Cochrane Review Manager, and a meta-analysis will be performed if possible for the statistical combination of at least two studies. The risk of bias of the randomised clinical trials will be evaluated by the Risk of Bias tool from Cochrane, and the risk of bias of the non-randomised intervention studies will be evaluated using the Downs and Black scale. The quality of the evidence and strength of the classification recommendations will be assessed by the Grading of Recommendations, Assessment, Development and Evaluation.Ethics and disseminationThis review will not evaluate individual patient information and therefore does not require ethical approval. The results will be disseminated through publications in peer-reviewed journals, presentations at conferences and the doctoral thesis of the leading author.PROSPERO registration numberCRD42018111383.

BackgroundLiterature supports a strong relationship between childhood maltreatment and mental illness but most studies reviewed are cross-sectional and/or use recall to assess maltreatment and are thus prone to temporality and recall bias. Research on the potential prospective impact of maltreatment reduction on the incidence of psychiatric disorders is scarce.MethodElectronic databases and grey literature from 1990 to 2014 were searched for English-language cohort studies with criteria for depression and/or anxiety and non-recall measurement of childhood maltreatment. Systematic review with meta-analysis synthesized the results. Study quality, heterogeneity, and publication bias were examined. Initial screening of titles and abstracts resulted in 199 papers being reviewed. Eight high-quality articles met eligibility criteria. Population attributable fractions (PAFs) estimated potential preventive impact.ResultsThe pooled odds ratio (OR) between any type of maltreatment and depression was 2.03 [95% confidence interval (CI) 1.37–3.01] and 2.70 (95% CI 2.10–3.47) for anxiety. For specific types of maltreatment and depression or anxiety disorders, the ORs were: physical abuse (OR 2.00, 95% CI 1.25–3.19), sexual abuse (OR 2.66, 95% CI 1.88–3.75), and neglect (OR 1.74, 95% CI 1.35–2.23). PAFs suggest that over one-half of global depression and anxiety cases are potentially attributable to self-reported childhood maltreatment. A 10–25% reduction in maltreatment could potentially prevent 31.4–80.3 million depression and anxiety cases worldwide.ConclusionThis review provides robust evidence of childhood maltreatment increasing the risk for depression and anxiety, and reinforces the need for effective programs and policies to reduce its occurrence.
