GRADE guidance 39: using GRADE-ADOLOPMENT to adopt, adapt or create contextualized recommendations from source guidelines and evidence syntheses.

BACKGROUND AND OBJECTIVE: The Grading of Recommendations, Assessment, Development and Evaluations (GRADE)-ADOLOPMENT methodology has been widely used to adopt, adapt, or de novo develop recommendations from existing or new guideline and evidence synthesis efforts. The objective of this guidance is to refine the operationalization for applying GRADE-ADOLOPMENT. METHODS: Through iterative discussions, online meetings, and email communications, the GRADE-ADOLOPMENT project group drafted the updated guidance. We then conducted a review of handbooks of guideline-producing organizations, and a scoping review of published and planned adolopment guideline projects. The lead authors refined the existing approach based on the scoping review findings and feedback from members of the GRADE working group. We presented the revised approach to the group in November 2022 (approximately 115 people), in May 2023 (approximately 100 people), and twice in September 2023 (approximately 60 and 90 people) for approval. RESULTS: This GRADE guidance shows how to effectively and efficiently contextualize recommendations using the GRADE-ADOLOPMENT approach by doing the following: (1) showcasing alternative pathways for starting an adolopment effort; (2) elaborating on the different essential steps of this approach, such as building on existing evidence-to-decision (EtDs), when available or developing new EtDs, if necessary; and (3) providing examples from adolopment case studies to facilitate the application of the approach. We demonstrate how to use contextual evidence to make judgments about EtD criteria, and highlight the importance of making the resulting EtDs available to facilitate adolopment efforts by others. CONCLUSION: This updated GRADE guidance further operationalizes the application of GRADE-ADOLOPMENT based on over 6 years of experience. It serves to support uptake and application by end users interested in contextualizing recommendations to a local setting or specific reality in a short period of time or with limited resources.

Protocol of a scoping review of systematic reviews and meta-analyses about COVID-19 vaccines and associated adverse events from vaccination.

The continuous dissemination of coronavirus disease of 2019 (COVID-19) literature can inform decision-makers and the public. Since the widespread use of COVID-19 vaccines, more systematic reviews have summarized the effectiveness and reported adverse events associated with vaccination. Previous systematic and scoping reviews on COVID-19 summarized various aspects surrounding COVID-19, however, a scoping review is needed to summarize the characteristics of COVID-19 vaccines and associated adverse events reported in systematic reviews and meta-analyses to provide comprehensive evidence for informed medical decision-making. We will conduct a scoping review concerning COVID-19 vaccines and adverse events from vaccines. We will search from December 2019 to present in Epistemonikos, Campbell Library, CINAHL (Ovid), MEDLINE (Ovid), Scopus, CENTRAL (Ovid), Web of Science, WHO COVID-19 database, Joanna Briggs Institute of Excellence, and COVID-19 Evidence Reviews resource. We will include systematic reviews, meta-analyses, or both of randomized controlled trials and observational studies and exclude individual randomized controlled trials and observational studies. Abstracts and full-texts will be screened prior to selection. Investigators will independently use a calibrated quantitative and qualitative data extraction sheet and rate the quality of articles with AMSTAR, resolving disagreements to aim for good agreement (≥80%). An updated scoping review of the characteristics and safety of COVID-19 vaccines would highlight the accuracy of the evidence to inform decision-making concerning COVID-19 vaccination.

Central and peripheral mechanisms of pain in fibromyalgia: scoping review protocol.

Fibromyalgia is characterised by widespread musculoskeletal pain, which may present with fatigue, depression, anxiety, sleep and cognitive disturbances. It is the second most prevalent rheumatic disease. An accurate diagnosis is challenging, since its symptoms may resemble diverse conditions such as carpal tunnel syndrome, Raynaud syndrome, Sjögren syndrome, amongst others. Neuropathic pain and autonomic dysfunction in fibromyalgia suggest the involvement of the nervous system. Ion channels, neurotransmitters and neuromodulators may play a role. Small fibre neuropathy (SFN) may also cause chronic widespread pain. SFN may occur in 50% of fibromyalgia patients, but its role in the disease is unknown. Despite several efforts to synthesise the evidence on the mechanisms for pain in fibromyalgia, there are few studies applying an integrative perspective of neurochemical, immunological, and neuroanatomical characteristics, and their relevance to the disease. This protocol aims to clarify the mechanisms of the central and peripheral nervous system associated with pain in fibromyalgia. We will retrieve published studies from Web of Science, MEDLINE, Scopus, EBSCOhost, Ovid and Google Scholar. All clinical studies or experimental models of fibromyalgia reporting imaging, neurophysiological, anatomical, structural, neurochemical, or immunological characteristics of the central or peripheral nervous systems associated with pain will be included. Exclusion criteria will eliminate studies evaluating pain without a standardised measure, studies written in languages different from Spanish or English that could not be appropriately translated, and studies whose full-text files could not be retrieved after all efforts made. A narrative synthesis will be performed.

An Effective Home-Based Particle Repositioning Procedure for Posterior Canal Benign Paroxysmal Positional Vertigo (BPPV).

Patients with benign paroxysmal positional vertigo (BPPV) find it difficult to visit the hospital many times for a standard Epley's maneuver performed only by a specialist. The aim of this study was to compare the efficacy of a home-based particle repositioning procedure (HBPRP) with the standard Epley's maneuver in treating patients with posterior canal BPPV. A prospective non-blinded randomized controlled study was conducted. Patients were randomized into two groups, where one group received the standard treatment and other received a new HBPRP. The vertigo scale, duration of nystagmus during Dix-Hallpike test and frequency of vertigo, were documented on first, second and third visits, with complications noted during the second and third visits. These parameters were compared between both the groups following the treatment, during all visits. The patients were randomized into 2 arms with 15 each. Those belonging to group 1 received Epley's maneuver and group 2 received HBPRP. There was no significant difference in the baseline characteristics of patients in both groups. Both groups of patients had significant improvement of symptoms at the end of the study. A comparison of both groups at 2nd and 3rd visits showed no differences in frequency of vertigo, reduction in vertigo scale and duration of nystagmus following Dix-Hallpike test between both groups. HBPRP is a safe and effective procedure and can be taught as a home-based treatment for patients diagnosed with posterior canal BPPV.

Adherence to literature search reporting guidelines in leading rheumatology journals' systematic reviews: umbrella review protocol.

Literature searches are important components of systematic reviews. They are not only informative of the retrieval process, but they also set the data to be analyzed and influence additional components of systematic reviews. Despite the available guidelines, several studies have shown that the quality of reporting in systematic reviews is deficient in several medical fields. Systematic reviews may not comply completely with those guidelines despite explicitly stating they do. This protocol intends to answer to what extent systematic reviews published in rheumatology journals have complied with the PRISMA's search strategy guidelines published in 2009. The objective of the study is to analyze the compliance with the PRISMA (2009) search strategy guidelines among systematic reviews published in leading rheumatology journals. Inclusion criteria for this umbrella review protocol are systematic reviews (with or without meta-analyses) that mention having followed the PRISMA statement (2009) in their methods section, and published in journals listed in the Rheumatology category of the Journal of Citations Report 2020. Exclusion criteria are articles published before 2009; retraction letters, notes, expressions of concern; systematic reviews using PRISMA 2020. Databases to be consulted are Web of Science, PubMed and Scopus, from inception to present. Data summaries will be presented in graphs, figures, tables and network maps. A narrative synthesis will be described. This protocol complies with guidelines such as PRISMA 2020, PRISMA-A, PRISMA-P, PRISMA-S, PRESS, and JBI Manual for evidence synthesis, as long as it is suitable for umbrella review protocols. Articles in any language will be considered.

The effect of Aronia consumption on lipid profile, blood pressure, and biomarkers of inflammation: A systematic review and meta-analysis of randomized controlled trials.

Plant derivatives, such as anthocyanin-rich phytochemicals, have been reported to elicit a positive effect on lipid profile. Therefore, the aim of this study was to systematically review and meta-analyze the effects of Aronia consumption on lipid profiles, blood pressure, and biomarkers of inflammation in randomized controlled trials. A systematic search was performed in PubMed/MEDLINE, Cochrane, and SCOPUS up to December 2018. Seven studies were identified and analyzed in this meta-analysis. Our study found a significant increase in high-density lipoprotein (HDL; weighted mean difference [WMD]: 1.48 mg/dl, 95% confidence interval, CI, [1.29, 1.68]) and diastolic blood pressure (WMD: 2.55 mmHg, 95% CI [0.63, 4.47]) following Aronia consumption. There was no significant effect on systolic blood pressure and C-reactive protein, tumor necrosis factor, and interleukin-1. Furthermore, subgroup analysis showed that cholesterol (WMD: -7.18, 95% CI [-13.90, -0.46]) and low-density lipoprotein (LDL; WMD: -5.84, 95% CI [-6.91, -4.77]) decreased more significantly in interventions less than 10 weeks in duration. Dose-response analysis demonstrated a significant reduction in triglyceride levels when dose of Aronia was increased to 300 mg/day. In conclusion, the results demonstrated a significant increase in HDL and reduction in total cholesterol and LDL among patients supplementing with Aronia.
