Project description:This is the protocol for a Campbell systematic review. The objectives are as follows: identify, appraise and bring together the evidence on the use of intergenerational practice.
Project description:Obstetric fistula is prevalent in low- and middle-income countries, with between 50,000 and 100,000 new cases each year. The World Health Organization aims to eradicate it by 2030 but a clear idea of the extant evidence is unavailable. This evidence map compiled evidence on treatments for obstetric fistula to identify potential knowledge gaps. The protocol for this work was published on the Open Science Framework (DOI: 10.17605/OSF.IO/H7J35). A survey was developed, piloted and distributed online through organisations with an interest in obstetric fistula and snowballing. Results informed the evidence map framework. Searches were run on MEDLINE, Embase, CENTRAL, Global Index Medicus and ScanMedicine on 16 February 2022 to identify potentially eligible systematic reviews, randomised controlled trials, cohort studies and case-control studies. Forward and backward citation chaining was undertaken on relevant systematic reviews and included studies. Studies were screened, coded and assessed for risk of bias by a single reviewer, with a second checking a proportion. The evidence map results were compared to survey results. Thirty-nine people responded to the survey, half of which were clinicians. Of 9796 records identified, 37 reports of 28 studies were included in the evidence map. Many included studies were at some risk of bias; for observational studies, this was predominantly due to lack of controlling for confounders. Most studies (71%) assessed surgical interventions alone. Reporting on other intervention types was limited. Regarding outcome measures most important to survey respondents, 24 studies reported on cure/improvement in obstetric fistula and 20 on cure/improvement in urinary incontinence. Reporting on quality of life, faecal incontinence and sexual function was limited. There is currently little robust evidence to guide patients and practitioners on the most effective treatment option for obstetric fistula. Further research is required to address evidence gaps identified.
Project description:BackgroundDespite a considerable reduction in child mortality, nearly six million children under the age of five die each year. Millions more are poorly nourished and in many parts of the world, the quality of education remains poor. Children are at risk from multiple violations of their rights, including child labour, early marriage, and sexual exploitation. Research plays a crucial role in helping to close the remaining gaps in child well-being, yet the global evidence base for interventions to meet these challenges is mostly weak, scattered and often unusable by policymakers and practitioners. This mega-map encourages the generation and use of rigorous evidence on effective ways to improve child well-being for policy and programming.ObjectivesThe aim of this mega-map is to identify, map and provide an overview of the existing evidence synthesis on the interventions aimed at improving child well-being in low- and middle-income countries (LMICs).MethodsCampbell evidence and gap maps (EGMs) are based on a review of existing mapping standards (Saran & White, 2018) which drew in particular of the approach developed by 3ie (Snilstveit, Vojtkova, Bhavsar, & Gaarder, 2013). As defined in the Campbell EGM guidance paper; "Mega-map is a map of evidence synthesis, that is, systematic reviews, and does not include primary studies" (Campbell Collaboration, 2020). The mega-map on child well-being includes studies with participants aged 0-18 years, conducted in LMICs, and published from year 2000 onwards. The search followed strict inclusion criteria for interventions and outcomes in the domains of health, education, social work and welfare, social protection, environmental health, water supply and sanitation (WASH) and governance. Critical appraisal of included systematic reviews was conducted using "A Measurement Tool to Assess Systematic Reviews"-AMSTAR-2 rating scale (Shea, et al., 2017).ResultsWe identified 333 systematic reviews and 23 EGMs. The number of studies being published has increased year-on-year since 2000. However, the distribution of studies across World Bank regions, intervention and outcome categories are uneven. Most systematic reviews examine interventions pertaining to traditional areas of health and education. Systematic reviews in these traditional areas are also the most funded. There is limited evidence in social work and social protection. About 69% (231) of the reviews are assessed to be of low and medium quality. There are evidence gaps with respect to key vulnerable populations, including children with disabilities and those who belong to minority groups.ConclusionAlthough an increasing number of systematic reviews addressing child well-being topics are being published, some clear gaps in the evidence remain in terms of quality of reviews and some interventions and outcome areas. The clear gap is the small number of reviews focusing explicitly on either equity or programmes for disadvantaged groups and those who are discriminated against.
Project description:A universal tool in the culture-based study of bacterial viruses (bacteriophages, or phages) is the agar overlay, which is used in the isolation of new viruses, and in their quantification and purification. Here, simple optimizations that increase efficiency and throughput in agar overlay based isolation and cultivation of virus-host systems are presented. The agar overlay is streamlined to minimize steps and materials. Serial purification of viruses from viral colonies (plaques) is optimized to eliminate steps by combining purification by serial re-streaking with the optimized agar overlay approach. Finally, recommendations are made for efficient archival and storage of virus plaques. In sum, this work presents: •Tube-free Agar Overlays: rapid plaque assays with fewer steps and materials•Molten Streaking for Singles: rapid tube-free serial purification of viruses•Archiving Plaques: saving virus purification for later.
Project description:The research question guiding the production of the youth employment evidence and gap map (EGM) is stated as follows: What is the nature and extent of the evidence base of impact evaluations and systematic reviews on youth employment programmes in the world? The primary objective of is to catalogue impact evaluations and systematic reviews on youth employment interventions to enhance discoverability of evidence by decision makers, development patterners and researchers, so as to promote evidence-based decision making in programming and delivery of youth employment initiatives. This evidence gap map is also a primary input into the implementation of Mastercard Foundation's strategy titled "Africa Works: Mastercard Foundation Strategy 2018-2030", which points out sharing of evidence-based knowledge and innovation with stakeholders as a key strategy to be used (Mastercard Foundation). The time frame for the development of the youth EGM will run from the last quarter of 2019 to December 2020. The five secondary objectives are: (i) To construct a framework for the classification of youth employment effectiveness studies. The objective will be achieved through the development of an intervention and outcome framework using an engaged consultative process involving the review team, Mastercard Foundation and other stakeholders. (ii) To identify available evidence, and clusters of evidence, including its quality rating. This will involve activities such as identification of studies using a standardised study search strategy, screening and coding of studies in EPPI Reviewer 4, which is a web-based software program for production of reviews. (iii) To create a map of youth employment effectiveness studies equipped with an appealing user-friendly web-based search content visualisation using interactive mapping software. To achieve this object, data coded in EPPI Reviewer 4 will be exported to another software (EPPI mapper) which is designed for generating EGMs. (iv) To produce a narrative report of the youth employment EGM. This will be achieved through analysis of data in EPPI Reviewer 4 and report writing. To disseminate the EGM to users to increase awareness to support evidence-informed decision-making across countries. We will achieve this objective by organising dissemination workshops, participating in conferences and hosting the evidence and gap on our websites.
Project description:IntroductionClinical research broadly aims to influence decision-making in order to promote appropriate healthcare. Funding agencies should prioritise research projects according to needed research topics, methodological and cost-effectiveness considerations, and expected social value. In Chile, there is no local diagnosis regarding recent clinical research that might inform prioritisation for future research funding. This research aims to comprehensively identify and classify Chilean health research studies, elaborating evidence gap maps for the most burdensome local conditions.Methods and analysisWe will search in electronic databases (MEDLINE, Embase, PsycINFO, CINAHL, LILACS and WoS) and perform hand searches to retrieve, identify and classify health research studies conducted in Chile or by authors whose affiliations are based in Chile, from 2000 onwards. We will elaborate evidence matrices for the 20 conditions with the highest burden in Chile (according to the Global Burden of Disease 2019) selected from those defined under the General Regime of the Health Guarantees Act. To elaborate the evidence gap maps, we will consider prioritised interventions and core outcome sets. To identify knowledge gaps and estimate redundant research, we will contrast these gap maps with the available international evidence of high or moderate certainty of evidence, for each specific clinical question. For this purpose, we will search systematic reviews using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach.Ethics and disseminationNo ethical approval is required to conduct this project. We will submit our results in both peer-reviewed journals and scientific conferences. We will aim to disseminate our findings through different academic platforms, social media, local press, among others. The final results will be communicated to local funding agencies and government stakeholders.DiscussionWe aim to provide an accurate and up-to-date picture of the research gaps-to be filled by new future findings-and the identification of redundant research, which will constitute relevant information for local decision-makers.
Project description:ObjectiveA systematic literature review (SLR; 2009-2014) to compare a target-oriented approach with routine management in the treatment of rheumatoid arthritis (RA) to allow an update of the treat-to-target recommendations.MethodsTwo SLRs focused on clinical trials employing a treatment approach targeting a specific clinical outcome were performed. In addition to testing clinical, functional and/or structural changes as endpoints, comorbidities, cardiovascular risk, work productivity and education as well as patient self-assessment were investigated. The searches covered MEDLINE, EMBASE, Cochrane databases and Clinicaltrial.gov for the period between 2009 and 2012 and separately for the period of 2012 to May of 2014.ResultsOf 8442 citations retrieved in the two SLRs, 176 articles underwent full-text review. According to predefined inclusion/exclusion criteria, six articles were included of which five showed superiority of a targeted treatment approach aiming at least at low-disease activity versus routine care; in addition, publications providing supportive evidence were also incorporated that aside from expanding the evidence provided by the above six publications allowed concluding that a target-oriented approach leads to less comorbidities and cardiovascular risk and better work productivity than conventional care.ConclusionsThe current study expands the evidence that targeting low-disease activity or remission in the management of RA conveys better outcomes than routine care.
