OMERACT uses an evidence-based framework known as the ‘OMERACT Filter Instrument Selection Algorithm’ (OFISA) to guide decisions in the assessment of outcome measurement instruments for inclusion in ...a core outcome set for interventional and observational clinical trials.
A group of OMERACT imaging and patient-centered outcome methodologists worked with imaging outcome groups to facilitate the selection of imaging outcome measurement instruments using the OFISA approach. The lessons learned from this work influenced the evolution to Filter 2.2 and necessitated changes to OMERACT's documentation and processes.
OMERACT has revised documentation and processes to incorporate the evolution of instrument selection to Filter 2.2. These revisions include creation of a template for detailed definitions of the target domain which is a necessary first step for instrument selection, modifications to the Summary of Measurement Properties (SOMP) table to account for sources of variability, and development of standardized reporting tables for each measurement property.
OMERACT Filter 2.2 represents additional modifications of the OMERACT guide for working groups in their rigorous assessment of measurement properties of instruments of various types, including imaging outcome measurement instruments. Enhanced reporting aims to increase the transparency of the evidence base leading to judgements for the endorsement of instruments in core outcome sets.

In life, you get the ‘hands’ you are dealt, and my ‘hand’ resulted in my being the third generation on my father's side of the family to be diagnosed with rheumatoid arthritis (RA), all of us around ...the age of 36. Turning on a lamp, opening a tin and getting food out to feed my cat, or even turning a key to unlock the door became a contortionist's feat. There was a special key holder for my house key and a large plastic triangle that fit over a lamp switch so I could turn the lamps on or off as well as large rubber bands for the doorknobs for better grip. In an ideal world, a person living with a chronic MSK disease like arthritis should be entitled to the benefit of an assessment by a PT and OT once a year to address any ongoing or new changes to their joints and the management challenges that that presents, and then a follow-up to assure that recommendations of assistive devices, exercises or treatment modalities are being done/used properly, that they are making a difference and that they are well managed within the parameters of the patient's life.
The human polyomavirus, JC virus (JCV) produces five tumor proteins encoded by transcripts alternatively spliced from one precursor messenger RNA. Significant attention has been given to replication ...and transforming activities of JCV's large tumor antigen (TAg) and three T' proteins, but little is known about small tumor antigen (tAg) functions. Amino-terminal sequences of tAg overlap with those of the other tumor proteins, but the carboxy half of tAg is unique. These latter sequences are the least conserved among the early coding regions of primate polyomaviruses.
We investigated the ability of wild type and mutant forms of JCV tAg to interact with cellular proteins involved in regulating cell proliferation and survival. The JCV P99A tAg is mutated at a conserved proline, which in the SV40 tAg is required for efficient interaction with protein phosphatase 2A (PP2A), and the C157A mutant tAg is altered at one of two newly recognized LxCxE motifs. Relative to wild type and C157A tAgs, P99A tAg interacts inefficiently with PP2A in vivo. Unlike SV40 tAg, JCV tAg binds to the Rb family of tumor suppressor proteins. Viral DNAs expressing mutant t proteins replicated less efficiently than did the intact JCV genome. A JCV construct incapable of expressing tAg was replication-incompetent, a defect not complemented in trans using a tAg-expressing vector.
JCV tAg possesses unique properties among the polyomavirus small t proteins. It contributes significantly to viral DNA replication in vivo; a tAg null mutant failed to display detectable DNA replication activity, and a tAg substitution mutant, reduced in PP2A binding, was replication-defective. Our observation that JCV tAg binds Rb proteins, indicates all five JCV tumor proteins have the potential to influence cell cycle progression in infected and transformed cells. It remains unclear how these proteins coordinate their unique and overlapping functions.
Although comprehensive and widespread guidelines on how to conduct systematic reviews of outcome measurement instruments (OMIs) exist, for example from the COSMIN (COnsensus-based Standards for the ...selection of health Measurement INstruments) initiative, key information is often missing in published reports. This article describes the development of an extension of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guideline: PRISMA-COSMIN for OMIs 2024. The development process followed the Enhancing the QUAlity and Transparency Of health Research (EQUATOR) guidelines and included a literature search, expert consultations, a Delphi study, a hybrid workgroup meeting, pilot testing, and an end-of-project meeting, with integrated patient/public involvement. From the literature and expert consultation, 49 potentially relevant reporting items were identified. Round 1 of the Delphi study was completed by 103 panelists, whereas round 2 and 3 were completed by 78 panelists. After 3 rounds, agreement (greater than or equal to 67%) on inclusion and wording was reached for 44 items. Eleven items without consensus for inclusion and/or wording were discussed at a workgroup meeting attended by 24 participants. Agreement was reached for the inclusion and wording of 10 items, and the deletion of 1 item. Pilot testing with 65 authors of OMI systematic reviews further improved the guideline through minor changes in wording and structure, finalized during the end-of-project meeting. The final checklist to facilitate the reporting of full systematic review reports contains 54 (sub)items addressing the review's title, abstract, plain language summary, open science, introduction, methods, results, and discussion. Thirteen items pertaining to the title and abstract are also included in a separate abstract checklist, guiding authors in reporting for example conference abstracts. PRISMA-COSMIN for OMIs 2024 consists of two checklists (full reports; abstracts), their corresponding explanation and elaboration documents detailing the rationale and examples for each item, and a data flow diagram. PRISMA-COSMIN for OMIs 2024 can improve the reporting of systematic reviews of OMIs, fostering their reproducibility and allowing end-users to appraise the quality of OMIs and select the most appropriate OMI for a specific application.
Foot and ankle involvement is common in rheumatic and musculoskeletal diseases (RMDs). High-quality evidence is lacking to determine the effectiveness of treatments for these disorders. Heterogeneity ...in the outcomes used across clinical trials and observational studies hinders the ability to compare findings, and some outcomes are not always meaningful to patients and end-users. The Core set of Outcome Measures for FOot and ankle disorders in RheumaTic and musculoskeletal diseases (COMFORT) study aims to develop a core outcome set (COS) for use in all trials of interventions for foot and ankle disorders in RMDs. This protocol addresses core outcome domains (what to measure) only. Future work will focus on core outcome measurement instruments (how to measure).
COMFORT: Core Domain Set is a mixed-methods study involving the following: (i) identification of important outcome domains through literature reviews, qualitative interviews and focus groups with patients and (ii) prioritisation of domains through an online, modified Delphi consensus study and subsequent consensus meeting with representation from all stakeholder groups. Findings will be disseminated widely to enhance uptake.
This protocol details the development process and methodology to identify and prioritise domains for a COS in the novel area of foot and ankle disorders in RMDs. Future use of this standardised set of outcome domains, developed with all key stakeholders, will help address issues with outcome variability. This will facilitate comparing and combining study findings, thus improving the evidence base for treatments of these conditions. Future work will identify suitable outcome measurement instruments for each of the core domains.
This study is registered with the Core Outcome Measures in Effectiveness Trials (COMET) database, as of June 2022: https://www.comet-initiative.org/Studies/Details/2081.
In recent years, projects to develop reporting guidelines have attempted to integrate the perspectives of patients and public members. Best practices for patient and public involvement (PPI) in such ...projects have not yet been established. We recently developed an extension of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), to be used for systematic reviews of outcome measurement instruments (OMIs): PRISMA-COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) for OMIs 2024. Patients and public members formed a small but impactful stakeholder group. We critically evaluated the PPI component in this project and developed recommendations for conducting PPI when developing reporting guidelines.
A patient partner was an integral research team member at the project development and grant application stage. Once the project started, five patient and public contributors (PPCs) were recruited to participate in the Delphi study; three PPCs contributed to subsequent steps. We collected quantitative feedback through surveys; qualitative feedback was garnered through a focus group discussion after the Delphi study and through debrief meetings after subsequent project activities. Feedback was thematically combined with reflections from the research team, and was predominantly positive. The following themes emerged: importance of PPI partnership, number of PPCs involved, onboarding, design of Delphi surveys, flexibility in the process, complexity of PPI in methodological research, and power imbalances. Impacts of PPI on the content and presentation of the reporting guideline were evident, and reciprocal learning between PPCs and the research team occurred throughout the project. Lessons learned were translated into 17 recommendations for future projects.
Integrating PPI in the development of PRISMA-COSMIN for OMIs 2024 was feasible and considered valuable by PPCs and the research team. Our approach can be applied by others wishing to integrate PPI in developing reporting guidelines.
To develop a prophylactic for organophosphorus (OP) poisoning utilizing catalytic bioscavengers, the circulatory stability of the enzymes needs to be increased. One strategy for increasing the ...bioavailability of OP bioscavengers is to target them to the surface of red blood cells (RBCs). Given the circulatory lifespan of 120 days for human RBCs, this strategy has the potential for creating a persistent pool of bioscavenger. Here we report the development of fusion proteins with a single chain variable fragment (scFv) of Ter119, a molecule that associates with glycophorin A on the surface of RBCs, and the VIID11 variant of paraoxonase 1 (scFv-PON1). We show that scFv-PON1 variants expressed by Trichoplusia ni larvae are catalytically active and that one variant in particular can successfully bind to the surface of murine RBCs both in vitro and in vivo. This study represents a proof of concept for targeting catalytic bioscavengers to the surface of RBCs and is an early step in developing catalytic bioscavengers that can remain in circulation for an extended period of time.
•Red blood cell targeting bioscavenger fusion proteins were successfully produced.•One variant was able to bind red blood cells with high efficiency in vitro.•The same variant targeted red blood cells in an in vivo study and was detectable for at least 24 h.

This paper describes the evolution and impact of Patient Research Partners (PRPs) in shaping research within OMERACT and provides a framework to enhance their engagement. This session explored one ...component of a validated framework to evaluate meaningful patient engagement. It provides insights, identifies opportunities for improvement, and recommends using the Patient Engagement in Research (PEIR) Framework, PEIR Plan Guide (workbook), and PEIRS-22 (scale) to guide and measure PRPs' engagement.
Before the conference, the team held planning sessions and selected the Feel-Valued component of the PEIR Workbook for exploration. During OMERACT 2023, we discussed this topic using the PEIR Plan Guide in an interactive plenary session.
The plenary session produced 72 items from 14 breakout tables addressing PEIR Framework themes.
This paper highlights the role and evolution of PRPs in shaping research within OMERACT. It emphasizes enhancing and accurately measuring PRP engagement through the PEIR Framework, PEIR Plan Guide, and PEIRS-22. The insights and methodologies presented aim to fortify future PRP engagement, ensuring it aligns with OMERACT's principles of patient-centred research.
