[Review of Reviews (Umbrella Reviews): Step-by-Step Guide]. / Revisão das Revisões (Revisões Umbrella): Guia Passo a Passo.

In recent years, as a result of the dramatic increase in the number of systematic reviews, a new type of systematic review, the 'systematic reviews of systematic reviews', also known as umbrella reviews, reviews of reviews, meta-reviews or synthesis of review, was developed. The aim of this article is to provide recommendations on how this type of systematic review should be conducted and reported to ensure its quality and usefulness. These reviews are designed to compile evidence from multiple systematic reviews of interventions into an accessible and usable document and are one of the highest levels of evidence synthesis.

Nos últimos anos, em consequência do aumento dramático do número de revisões sistemáticas, surgiu um novo tipo de revisões sistemáticas, as revi- sões sistemáticas das revisões sistemáticas, também conhecidas como umbrella reviews, reviews of reviews, meta-reviews, ou synthesis of review. O objetivo deste artigo é fornecer recomendações sobre como este tipo de revisão sistemática deve ser conduzido e relatado para garantir a sua qualidade e utilidade. Estas revisões são concebidas para compilar evidências de múltiplas revisões sistemáticas de intervenções num documento acessível e utilizável e constituem um dos níveis mais elevados de síntese de evidência.

Integrating evidence and causal mapping of help-seeking behaviour of migrant women with postpartum depression in Shanghai, China: a scoping review protocol.

INTRODUCTION: The estimated prevalence of postpartum depression (PPD) worldwide, in China, and Shanghai is 17.2%, 18.0% and 23.2%, respectively. In 2021, Shanghai housed a population of 3.2 million childbearing-age migrant women, most of whom migrated to the city with their husbands for economic reasons. There is a general lack of help-seeking behaviour for mental disorders in China due to the perceived risk of social stigmatisation. In Shanghai, 70% of women did not seek professional help for perinatal mental health problems. We aim to gather information from multiple perspectives, such as the migrant women with PPD and perinatal depression (PND), their caregivers, health service providers and communities, to understand the help-seeking behaviour of postpartum migrant women with PPD or PND in China. METHODS AND ANALYSIS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework for Scoping Reviews will guide this review. A bilingual research librarian developed a comprehensive search strategy to retrieve published and unpublished English and Chinese studies involving factors influencing women's PPD or PND help-seeking behaviour in China. This literature includes perceptions, views, patterns, acceptance and refusal, tendencies, probability, service accessibility and utilisation, and facts. We will search PubMed, Embase, Web of Science and CINAHL for English literature and CINKI for Chinese literature. Backward and forward snowball approaches will be used to identify additional relevant papers from the reference lists of selected papers. Two independent reviewers will screen the title and abstract and review the full text of selected papers to identify eligible articles for data extraction. We will build a Microsoft Access database to record the extracted data. The results will be presented in tables and a causal map to demonstrate the relationships between extracted variables and help-seeking behaviours for PPD and PND. A conceptual simulation model will be formulated based on the information from the literature to validate the logic of the relationships between variables, identify knowledge gaps and gain insights into potential intervention approaches. Experts and stakeholders will be invited to critique and comment on the results during group model building (GMB) workshops in Shanghai. These comments will be essential to validate the findings, receive feedback and obtain additional insights. ETHICS AND DISSEMINATION: The literature review component of our study does not require ethical approval because the information and data collected will be obtained from publicly available sources and will not involve human subjects. Our collaborating research partner, International Peach Maternal Child Hospital, obtained the IRB approval (GKLW-A-2023-020-01) for screening and enrolling participants in GMB workshops. Stanford University received IRB approval under protocol number 67 419. The full review will be presented at a relevant conference and submitted to a peer-reviewed scientific journal for publication to report findings.

Mapping evidence on the distribution of uterine fibroids in sub-Saharan Africa: A scoping review protocol.

BACKGROUND: Uterine fibroids are the most common pelvic benign tumours found in reproductive-aged women and may affect up to 70% of all women by menopause. Uterine fibroids place a heavy burden on women and society resulting in poor quality of life, impaired self-image, and impaired social, sexual, emotional, and physical well-being of affected individuals. AIM: This study aims to map the evidence on the burden of uterine fibroids in Sub-Saharan Africa; uterine fibroids' burden by age, uterine fibroids' geographic burden, uterine fibroids' cost estimation and reported experiences among women diagnosed with uterine fibroids. SETTING: Articles will be selected from countries within Sub-Saharan Africa. METHODS AND ANALYSIS: This scoping review will be guided by the Arksey & O'Malley framework, enhanced by Levac et al (2010). The following electronic databases will be searched; PubMed, EBSCOhost (Cumulated Index to Nursing and Allied Health Literature and Health Source), Medical Literature Analysis and Retrieval System Online, Cochrane Library, Scopus, Web of Science, Africa Journal Online, and Google Scholar. The Population Concept and Context (PCC) framework will be used and the PRISMA flow diagram will also be used to show the literature search and selection of studies. Descriptive data analysis will be used; results will be presented in themes, narrative summaries, tables, and charts. DISCUSSION: The study anticipates finding relevant literature on the distribution of uterine fibroids, the burden of uterine fibroids in terms of geographic distribution, age distribution, and cost approximation related to the disease. This will assist in identifying research gaps to guide future research contribute to the body of scientific knowledge and develop preventative strategies for the disease.

Leishmaniases in Ethiopia: a scoping review protocol to determine the scope of research and remaining gaps.

INTRODUCTION: The leishmaniases are among the group of neglected tropical diseases that cause significant morbidity and mortality each year. Currently, the East Africa region has the highest visceral leishmaniasis burden in the world. Ethiopia is one of the East African countries that reports both visceral and cutaneous forms of the disease. As part of the Nairobi Declaration, Ethiopia showed commitment to the elimination of visceral leishmaniasis by 2030. In this endeavour, it is important to understand the scope of research conducted on leishmaniases in the country and identify where the research gaps exist. Determining the research landscape is vital in the plan towards leishmaniases control and elimination. It will help to reference conducted research, determine if systematic reviews are warranted and help prioritise future research directions. METHODS AND ANALYSIS: This protocol was developed with reference to the JBI Scoping Review Methodology Group's guidance on conducting scoping reviews and the PRISMA-ScR reporting guidelines for scoping reviews. The following databases will be searched: PubMed, Embase via Embase.com, Web of Science Core Collection, Cochrane CENTRAL, Global Index Medicus, ClinicalTrials.gov, the Pan African Clinical Trials Registry and PROSPERO. Locally published literature that may not be indexed in the above-mentioned systems will be identified through team members familiar with the setting. Each record will be dually and blindly reviewed in an abstract-title screen and full-text screen using inclusion-exclusion criteria. Included articles must contain an in-depth discussion of leishmaniasis in Ethiopia. Data extracted will consist of study themes, study types, and categories and subcategories each defined in the developed codebook, in addition to type of leishmania, year of publication, funding source and the number of citations. Results will be reported with summary statistics. ETHICS AND DISSEMINATION: Individual consenting and ethical approvals are not applicable. We plan to disseminate our findings to the appropriate stakeholders.

Methods to advance health equity and social justice in healthcare: Protocol for a scoping review on the utilisation of routinely collected data.

BACKGROUND: Many areas of healthcare are impacted by a paucity of research that is translatable to clinical practice. Research utilising real-world data, such as routinely collected patient data, may be one option to efficiently create evidence to inform practice and service delivery. Such studies are also valuable for exploring (in)equity of services and outcomes, and benefit from using non-selected samples representing the diversity of the populations served in the 'real world'. This scoping review aims to identify and map the published research which utilises routinely collected clinical healthcare data. A secondary aim is to explore the extent to which this literature supports the pursuit of social justice in health, including health inequities and intersectional approaches. METHOD: This review utilises Arksey and O'Malley's methodological framework for scoping reviews and draws on the recommended enhancements of this framework to promote a team-based and mixed methods approach. This includes searching electronic databases and screening papers based on a pre-specified inclusion and exclusion criteria. Data relevant to the research aims will be extracted from included papers, including the clinical/professional area of the topic, the source of data that was used, and whether it addresses elements of social justice. All screening and reviewing will be collaborative and iterative, drawing on strengths of the research team and responsive changes to challenges will be made. Quantitative data will be analysed descriptively, and conceptual content analysis will be utilised to understand qualitative data. These will be collectively synthesised in alignment to the research aims. CONCLUSION: Our findings will highlight the extent to which such research is being conducted and published, including gaps and make recommendations for future endeavours for real-world data studies. The findings from this scoping review will be relevant for practitioners and researchers, as well as health service managers, commissioners, and research funders.

Multidisciplinary understanding of modifiable physical disability risk factors for health professionals: A scoping review protocol.

INTRODUCTION: Physical disability represents a major burden to health and lifespan, particularly as the proportion of older adults within the United States is expected to grow. Prevention efforts for physical disability targets methods and strategies to decrease modifiable risk factors. Potential challenges for health professionals may exist in synthesizing and interpreting this broad spectrum of literature due to the discipline-specific nuance of language used, practice type or specialty, and lack of interdisciplinary resources. This scoping review will map and synthesize the literature across healthcare disciplines to identify modifiable risk factors and the evidence related to their ability to predict physical disability. We will also draw attention to the possibility of modifiable risk factors for physical disability being operationalized as pre-disability in order to strengthen primary and secondary prevention efforts. METHODS: A planned search strategy using physical disability terminology will be searched in English across MEDLINE, CINAHL, Health Source, PEDro, and REHABDATA by two reviewers in line with our review objectives and inclusion criteria. Eligibility for inclusion include peer-reviewed primary research published in the English language and have established a relationship between a person-level measurable characteristic that is modifiable by changes in lifestyle behaviors and any of the commonly accepted terms used to categorize or describe physical disability. EXPECTED RESULTS: Presentation of results will be using the PRISMA flowchart, with additional mapping and synthesis of evidence for modifiable risk factors for physical disability to clarify divergent terms used in classifying and measuring these factors and their potential for prediction of physical disability. EXPECTED CONCLUSION: It is anticipated that this scoping review will identify and highlight a variety of modifiable risk factors for physical disability that may aid primary and secondary prevention efforts for health professionals.

Impact of C-level positions on hospital performance: a scoping review protocol.

INTRODUCTION: The objective of this scoping review is to identify evidence of the impact of hospital managers in top management (c-suite) on hospital performance. Managers generally have various effects on organisational objectives of their organisations. In recent years, the healthcare sector has experienced alterations in hospital governance structures, together with the emergence of new c-suite positions, aligning more closely with those found in private organisations. Their impact on hospital performance (ie, quality of care) is not well known. This scoping review seeks to identify all the available evidence of their impact on the organisational objectives. This scoping review will include primary studies, reviews and commentaries that describe the impact of top management team members on organisational outcomes in a hospital setting. METHODS AND ANALYSIS: The search strategy aims to locate both published and unpublished documents (ie, grey literature) using a three-step search strategy. An exploratory search of Medline and Google Scholar identified keywords and Medical Subject Headings terms. A second search of Medline (PubMed), Web of Science Core Collection, ScienceDirect, Business Source Premier (EBScoHost), JSTOR, BASE, Lens.org and the Google Search Engine will be performed. The scope of the search will cover 1990-present time using English search terms. Manual searching by two reviewers will be added to the search strategy. The identified documents will be independently screened, selected by two researchers and extracted by one researcher. The data are then presented in tables and graphics coupled with a descriptive summary. ETHICS AND DISSEMINATION: As this study neither involves human participants nor unpublished secondary data, an ethics approval is not required. Findings will be disseminated through professional networks, conference presentations and publication in a scientific journal. TRIAL REGISTRATION NUMBER: The protocol was registered on the Open Science Framework (https://doi.org/10.17605/OSF.IO/EBKUP).

Paediatric out-of-hospital clinical deterioration: a mixed-methods scoping review protocol.

INTRODUCTION: In pre-hospital settings, identifying a deteriorating child can be challenging, especially considering that the proportion of paediatric patients with acute illnesses is lower compared with adults. This challenge is exacerbated in pre-hospital settings, where information might be scarce. Physiological alterations indicating changes in a patient's condition can be detected hours preceding a cardiac arrest. Therefore, maintaining continuous monitoring of the patient's clinical condition is crucial to detecting any physiological changes promptly, facilitating early identification of critical illness. This scoping review aims to assess the extent, range and nature of published research related to recognising paediatric out-of-hospital clinical deterioration by pre-hospital staff. METHODS AND ANALYSIS: This scoping review is registered with the Open Science Framework. The review will follow the Joanna Briggs Institute's (JBI) methodology for scoping reviews. A systematic search of relevant databases (MEDLINE, EMBASE, Web of Science, CINAHL and Scopus) will be conducted. In this scoping review, all types of study designs including quantitative and qualitative studies will be considered. The inclusion is limited to English-language studies published between January 1990 and March 2024. Two independent reviewers (AG and SS) will conduct a thorough screening of titles and abstracts against the pre-defined inclusion criteria for the review. For the selected citations, the full texts will undergo detailed assessment by the two reviewers, ensuring alignment with the inclusion criteria. A quality assessment of the included studies will be done using the Mixed Methods Appraisal Tool. The findings will be presented using diagrams or tables, supplemented by narrative summaries following the JBI guidelines. ETHICS AND DISSEMINATION: Ethical approval is not required. The findings will be disseminated through publication in a peer-reviewed journal and presentation at conferences and/or seminars.

Frameworks describing the transition to open labour employment for persons with mild and moderate intellectual disability: a scoping review protocol.

INTRODUCTION: Persons with mild and moderate intellectual disability (MMID) have the right to participate in all aspects of society and be afforded equal opportunities to realise their full potential. However, it is a challenge for persons with MMID to find and maintain employment due to many different barriers. Currently, there is no contextually relevant framework in South Africa that considers the unique employment support needs and accommodation of persons with MMID, which can guide and inform the transition to employment interventions, strategies and national policy directives. METHODS AND ANALYSIS: The proposed scoping review will be guided by the methodological framework developed by a working group from the Joanna Briggs Institute (JBI) and the JBI Collaboration. The search for relevant studies will be conducted across 12 research databases. Reference mining of review studies will be conducted. A three-step search strategy will be used, including the use of information management software to manage the search results. Three independent reviewers will screen the full-text studies to finalise the list of included and excluded studies. Included studies will be assessed for methodological quality using a critical appraisal tool. Data will be charted by one independent reviewer and assessed by two independent reviewers, using a data charting instrument. The data chart will be presented using tables and charts describing the demographic features of the reviewed studies, with an explanation of the thematically analysed results. ETHICS AND DISSEMINATION: This scoping review has received ethical approval (BM22/10/11). A summary of the findings of the study will be published in a peer-reviewed journal. This scoping review will contribute to a better understanding of the key characteristics or factors underpinning the components of a multilevel transition to employment framework that will result in open labour market employment for persons with MMID.

Exploring the literature on racism and health practitioner regulation: a scoping review protocol.

INTRODUCTION: Racism in healthcare leads to significant harm to healthcare professionals and the clients, families and communities they serve. Increasingly, health practitioner regulators-responsible for protecting the public and ensuring practitioner competence-are recognising the importance of reforming policies and practices to contribute to antiracist regulatory approaches. Examples of this work include developing specific standards of practice related to antiracism and antidiscrimination, supporting education and training, re-evaluating discriminatory licensure policies for internationally educated professionals and reforming internal governance structures to address unconscious bias. An understanding of the current state of literature can help identify knowledge gaps and inform the development of research agendas that can build the evidence base required to improve health practitioner regulators' approaches to addressing racism.The objective of this scoping review is to explore the nature, extent and range of literature focused on racism and health practitioner regulation and identify gaps in the literature. METHODS AND ANALYSIS: The review will be conducted in accordance with the Joanna Briggs Institute guidelines for scoping reviews. Database searches will include OVID MEDLINE, EMBASE, CINAHL, Scopus and Web of Science Core Collection. The review will include papers that discuss how health practitioner regulation can contribute to and perpetuate interpersonal and institutional racism, and how regulatory policies and practices can help address racism. We will also search for grey literature using the websites of leading regulatory organisations. Data will be analysed using descriptive statistics and conventional content analysis. Findings will be presented using evidence tables and a narrative summary. Reporting will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. ETHICS AND DISSEMINATION: Ethics approval is not applicable to this review protocol. Findings will be disseminated through presentations, meetings with health practitioner regulators and a publication in a peer-reviewed journal.

Uncovering the state of knowledge about healthcare gentrification: a scoping review protocol.

INTRODUCTION: Healthcare gentrification is the process in which the distribution of healthcare resources within a neighbourhood affects residents' access to healthcare services. To understand the complexity of healthcare access and to consider the socio-structural dimensions affecting equity in access to care, we aim to explore how healthcare gentrification has been described in the scientific literature and to document the reported relations between gentrification and healthcare access. METHODS AND ANALYSIS: We will conduct a scoping review from data published from inception to September 2024 based on the methodology developed by Arksey and O'Malley (2005) and improved by Levac et al (2010). We will search the following databases: MEDLINE (OVID), Embase (embase.com), CINAHL Plus with Full Text (EBSCO), Web of Science and Geobase (Engineering Village). The review will be conducted from February 2024 to September 2024. The search strategy will be elaborated in conjunction with a professional librarian. Screening of titles and abstracts and full-text screening will be done in duplicates. A third reviewer will arbitrate discrepancies during the screening process. We will present our results narratively. ETHICS AND DISSEMINATION: This scoping review does not require ethical approval since it will be collected from publicly available documents. The results of this scoping review will also be presented as a scientific article, scientific conferences, research webinars also in social media, workshops and conferences organised by healthcare organisations or academic institutions or on any appropriate platform.

Defining the gaps in transitional care to adulthood for patients in paediatric surgical specialties: a scoping review protocol.

INTRODUCTION: Transitioning patients from their paediatric centres to adulthood is an important subject for many of these patients living with different chronic pathologies. There are few studies that assess its effectiveness in paediatric surgical pathologies. The overall objective of this scoping review is to assess the extent of the literature describing transitional programmes dedicated to young patients living with surgical conditions. The primary question will look to assess what transitional programmes are available for young patients living with surgical conditions either operated or not. METHODS AND ANALYSIS: The proposed scoping review will follow guidelines described by the Joanna Briggs Institute manual described by Peters et al in 2020. This protocol will employ the Preferred Reporting Items for Systematic review and Meta-Analysis Protocols checklist. The concept that will be included in this review is the exposure of these patients to a transition of care pathway or care programmes. Patients between the ages of 16 and 30 with a surgical condition will be included. There will be no comparator. No specific outcomes will be assessed, however, the outcomes that will be found from the transition programmes will be reviewed. A knowledge synthesis librarian will search MEDLINE All (Ovid), Embase (Ovid), Web of Science Core Collection (Clarivate) and CINAHL Complete (EBSCOhost). The literature search will be limited to 2000 onwards publications. No language or age group limitation will be applied. The reference list of all included sources of evidence will be screened for additional studies. Screening of search results and data extraction from included studies will be completed in Covidence by two independent reviewers. We will also use the PAGER (Patterns, Advances, Gaps, Evidence for practice and Research recommendations) framework to report and summarise the results. ETHICS AND DISSEMINATION: This review does not require ethics approval. Our dissemination strategy includes peer review publication, conference presentation, co-constructed guidelines with stakeholders and policymakers. TRIAL REGISTRATION: This review is registered on OSF.

Pediatric dentistry systematic reviews using the GRADE approach: methodological study.

BACKGROUND: To assess the reporting of the certainty of the evidence using the GRADE approach in systematic reviews of interventions in pediatric dentistry. METHODS: The inclusion criteria were systematic reviews of randomized clinical trials (RCTs) and non-randomized studies of interventions (NRSIs) in pediatric dentistry that reported the certainty of the evidence through the GRADE approach. Paired independent reviewers screened the studies, extracted data, and appraised the methodological quality using the Assessing the Methodological Quality of Systematic Reviews (AMSTAR 2) tool. The certainty of the evidence was extracted for each outcome. A descriptive analysis was conducted. RESULTS: Around 28% of pediatric dentistry reviews of interventions used the GRADE approach (n = 24). Twenty reviews reported 112 evidence outcomes from RCTs and 13 from NRSIs using GRADE evidence profile tables. The methodological quality was high (16.7%), moderate (12.5%), low (37.5%), and critically low (33.3%), fulfilling the majority of the AMSTAR 2 criteria. The certainty of the evidence for outcomes generated from RCTs and NRSIs was very low (40.2% and 84.6%), low (33.1% and 7.7%), moderate (17.8% and 7.7%), and high (9.8% and 0.0%). The main reasons to downgrade the certainty were due to (for RCTs and NRSIs, respectively): risk of bias (68.8% and 84.6%), imprecision (67.8% and 100.0%), inconsistency (18.8% and 23.1%), indirectness (17.8% and 0.0%), and publication bias (7.1% and 0.0%). CONCLUSION: The proportion of systematic reviews assessing the certainty of the evidence using the GRADE approach was considered small, considering the total initial number of published pediatric dentistry reviews of intervention. The certainty of the evidence was mainly very low and low, and the main problems for downgrading the certainty of evidence were due to risk of bias and imprecision. REGISTRATION: PROSPERO database #CRD42022365443.

Supporting Time-Critical Decision Making: The Creation of a Nurse-Led Rapid Literature Review Service.

Due to shifting priorities and unforeseen challenges, nurse leaders often lack sufficient time and resources to systematically review and appraise the available literature in search of the best evidence to guide decisions. A nurse-led rapid review service can produce accelerated knowledge synthesis and contextualized translation of evidence in a resource-efficient manner. This article describes a nurse-led rapid review service implemented at a large academic medical center and provides a reproducible process to guide other healthcare organizations in developing similar programs.

Randomised controlled trials in vascular access devices in emergency departments: a scoping review protocol.

BACKGROUND: The significance of vascular access devices for patients in the emergency department (ED) is undeniable. When it comes to evaluating the effectiveness of interventions, randomised controlled trials (RCTs) stand out as the most reliable sources of evidence compared with other study designs. AIM: To explore and synthesise the findings from RCTs related to vascular access devices in the ED setting. METHODS: A systematic search will be conducted in electronic medical databases including the Cochrane Central Register of Controlled Trials, Pubmed, CINAHL and Embase databases. All RCTs focusing on peripheral intravenous catheters, central venous catheters and intraosseous catheters, published in English and Chinese in peer-reviewed journals within the past decade, will be included. CONCLUSION: This scoping review will summarise the current state of evidence for vascular access devices in the ED setting. This will identify gaps in the literature and, in turn, assist clinicians and researchers in pinpointing areas for future exploration and provide a valuable guide for future research.

Health system adaptations for extreme heat: Protocol for an international scoping review of reviews.

OBJECTIVE: The objective of this study is to map the international evidence for extreme heat related adaptation strategies by health systems, with a particular focus on how heat-vulnerable populations and local situational awareness are considered in these strategies. INTRODUCTION: Since the Paris Climate Accords in 2015, awareness has increased of the health risks posed by extreme heat along with interest in adaptations which aim to reduce heat-health-risks for vulnerable populations. However, the extant literature on these adaptations suggest they are insufficient, and call for research to examine whether, how, and what adaptations for extreme heat are effective as public health interventions. INCLUSION CRITERIA: We will include English-language review articles describing and/or evaluating health system adaptations for extreme heat. Health systems will be defined broadly using the WHO Building Blocks model [1] and adaptations will range from the individual level to institutional, regional and national levels, with particular attention to localisation and the protection of vulnerable individuals. METHODS: A comprehensive literature search of the published literature will be conducted using MEDLINE, Embase, CINAHL, the Cochrane Library and Web of Science. Searches will be limited to reviews published since 2015 in the English language. Results will be exported to EndNote for screening (with a sample checked by two reviewers to ensure consistency). A complementary search for related reports by major international agencies (e.g. WHO; International Association of Emergency Managers), as well as local searches for current guidance and case studies, will be conducted in parallel. Data from included papers will be presented in tables with a narrative commentary.

Exploring power and power sharing in participatory health research partnerships: A scoping review protocol.

INTRODUCTION: Participatory health research (PHR) as a research paradigm, guides the research process and strives to achieve positive change in society in the interest of people's health. In this scoping review, PHR will be used as an umbrella term considering a wide range of collaborative research approaches in the health context. PHR is conducted 'with' or 'by' those it intends to benefit, as opposed to 'on' and 'for' them. Their involvement throughout the research process seeks to shift power and decision-making from where they traditionally lay within academia toward community, patient and public end-users. Research cannot be truly participatory without concurrently addressing power dynamics within the partnership and power imbalances in decision making. Therefore, power sharing can be defined as a major factor in building effective academic-community collaborations. This scoping review aims to identify, clarify, and map existing literature on power and power sharing in PHR from both theoretical and practical perspectives. Specifically, we will explore how power is conceptualised throughout the literature, and how power and power sharing are applied and addressed in real-life PHR partnerships. MATERIALS AND METHODS: This scoping review will be conducted in accordance with the guidelines outlined in the Joanna Briggs Institute (JBI) Reviewer's Manual. This scoping review will consider both empirical and non-empirical research that report on understanding power and power sharing in participatory health research partnerships. All appropriate studies will be retrieved from the following five electronic databases: PubMed, Scopus, Embase, PsycINFO, SocIndex. This review will be limited to articles published in English and from January 1998 to March 2024. As the scoping review aims to capture more than peer-reviewed and published literature, it will also include grey literature such as theses and dissertations, reports, conference proceedings, and editorials. Data from the included literature will be extracted based on the data extraction tool, defined in advance. ETHICS AND DISSEMINATION: As primary data will not be collected, ethical approval is not required to conduct the scoping review. The findings of this study will be disseminated through peer-reviewed publications.

Methodological approaches in graded dental ceramics: a scoping review protocol.

OBJECTIVES: This review will map the various methodological approaches used in graded dental ceramics and distinguish their material characteristics and properties. The aim is to identify gaps in the development and application of grading in dental ceramic systems. INTRODUCTION: The advantage of functionally graded materials is the absence of the weakest link, with no distinct boundaries, thereby eliminating the possibility of stress concentrations at the interfaces. Functionally graded materials are well established in nature, such as in human teeth, bone, and the bio-tissues of plants and animals. This concept has also been explored in dental ceramics to enhance fatigue resistance and strength. INCLUSION CRITERIA: This review will include observational studies and interventional studies, such as in vitro and experimental studies, on functionally graded dental ceramic systems. Studies that use finite element analysis to evaluate stress distributions, and studies on the mechanical performance of graded dental ceramics, irrespective of the type of ceramic material, design, or thickness of graded layers, will be considered. METHOD: The review will follow the JBI methodology for scoping reviews and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. MEDLINE (PubMed), Scopus, ProQuest Dissertations and Theses (EBSCOhost), Cochrane CENTRAL, and Google Scholar will be searched for English language studies. The search strategy will be based on MeSH terms and free-text specific terms, and will be adapted for each database. Two independent reviewers will screen titles and abstracts, and extract data from selected sources. The data extracted from the selected studies will be analyzed and presented in the form of tables and figures. REVIEW REGISTRATION: Open Science Framework: https://osf.io/ahsp7.

Factors associated with the quality of corneas retrieved for transplantation by Eye Banks: a scoping review protocol.

INTRODUCTION: The cornea is an avascular and transparent layer of connective tissue crucial to retinal image quality. Diseases can impair its quality, affecting vision. Keratoplasty is the only therapy capable of restoring vision quality in severe corneal involvement. Despite the established practice of transplantation, access to corneal tissue is limited in many places, and the quality of retrieved corneas is not always adequate, resulting in disqualification. Not all factors affecting tissue quality are fully understood due to the multifactorial nature of processes and variations in procedures globally. OBJECTIVE: The objective is to map the global literature to establish the factors associated with the clinical and sociodemographic conditions of donors, and the conditions inherent in the processing of corneas that can influence the quality of this tissue for transplantation purposes. METHODS AND ANALYSIS: A scoping review will be developed based on the methodological framework of the Joanna Briggs Institute. The scientific report will follow the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension checklist for Scoping Reviews. Searches will be conducted in 30 indexed and 12 grey literature databases, without time or location restrictions. The selection of studies will be carried out in three distinct phases: screening, eligibility and inclusion. After defining the sample, data from the selected studies will be systematically extracted into an electronic spreadsheet. The results will be presented descriptively through tables and graphs of absolute and relative frequency. In addition, the PRISMA Scoping Review flow chart will be presented to present the process of searching, including and excluding articles and documents. ETHICS AND DISSEMINATION: This scoping review study does not require prior ethical approval as it uses publicly available and already published studies. The research protocol is registered in the Open Science Framework (osf.io/bw6r7). The findings will be submitted for publication in peer-reviewed scientific journals and presented at ophthalmology and/or transplantation conferences through oral presentations or posters.
