Transcriptomic and metabolomic responses to varying nutrient conditions reveal new insights into pitcher formation in Nepenthes khasiana.

Nepenthes are carnivorous plants that colonize habitats poor in soil nutrients. To survive, Nepenthes develop pitchers capable of capturing and digesting attracted prey. Prey-derived nutrients are then absorbed to support plant growth and reproduction. So far, pitcher formation in Nepenthes is a poorly understood biological process. To shed light on the formation of Nepenthes pitchers, we grew dissected shoot apices of 3-month-old N. khasiana seedlings in Murashige and Skoog (MS) medium of varying strengths viz. full-strength MS (1 MS), quarter-strength MS (1/4 MS), and one-eighth strength MS (1/8 MS), including those lacking nitrogen (N), phosphorus (P), and potassium (K) and in the presence of N-1-naphthylphthalamic acid (NPA). We sequenced the transcriptome and performed gas chromatography-mass spectrometry to determine changes in gene expression patterns and primary metabolite accumulations in response to the varying nutrient conditions. Shoots grown in 1 MS or NPA-containing 1/4 MS and 1/8 MS failed to develop pitchers. Remarkably, pitcher formation is restored when N was removed from 1 MS. Transcriptomic response to nutrient-sufficient and nutrient-deficient conditions are associated with the enrichment of several defence-related genes, including two JA-mediated defence response genes, WRKY51 and WRKY11, respectively. Further, metabolomic response to the varying nutrient conditions identifies glutamic acid as a key metabolite, accumulating at lower and higher levels in shoots with and without pitchers, respectively. Together, our findings suggest that failure to form pitchers may be associated with the suppression of the JA-signalling pathway, whereas the induction of the JA-mediated defence response is linked to pitcher formation in N. khasiana.

An Environmental Scan and Appraisal of Patient Online Resources for Managing Rheumatoid Arthritis Flares.

OBJECTIVE: To conduct an environmental scan and appraisal of online patient resources to support rheumatoid arthritis (RA) flare self-management. METHODS: We used the Google search engine (last search March 2023) using the terms "rheumatoid arthritis" and "flare management." Additional searches targeted major arthritis organizations, as well as regional, national, and international resources. Appraisal of the resources was conducted by 2 research team members and 1 patient partner to assess the understandability and actionability of the resource using the Patient Education Materials Assessment Tool (PEMAT). Resources rating ≥ 60% in both domains by either the research team or the patient partner were further considered for content review. During content review, resources were excluded if they contained product advertisements, inaccurate information, or use of noninclusive language. If content review criteria were met, resources were designated as "highly recommended" if both patient partners and researchers' PEMAT ratings were ≥ 60%. If PEMAT ratings were divergent and had a rating ≥ 60% from only 1 group of reviewers, the resource was designated "acceptable." RESULTS: We identified 44 resources; 12 were excluded as they did not pass the PEMAT assessment. Fourteen resources received ratings ≥ 60% on understandability and actionability from both researchers and patient partners; 10 of these were retained following content review as "highly recommended" flare resources. Of the 18 divergent PEMAT ratings, 8 resources were retained as "acceptable" following content review. CONCLUSION: There is high variability in the actionability and understandability of online RA flare materials; only 23% of resources were highly recommended by researchers and patient partners.

Investigating the influence of patient eligibility characteristics on the number of deferrable rheumatologist visits: planning for a patient-initiated follow-up (PIFU) strategy.

OBJECTIVE: Patient-initiated follow-up (PIFU) for rheumatoid arthritis (RA) is a model of care delivery wherein patients contact the clinic when needed instead of regularly scheduled followups. Our objective was to investigate the influence of different patient eligibility characteristics on the number of potentially deferred visits to inform future implementation of a PIFU strategy. METHODS: We conducted a retrospective chart review of seven rheumatologists' practices at two university-based clinics between 01/03/2021-28/02/2022. Data extracted included the type and frequency of visits, disease management, comorbidities, and care complexities. Stable disease was defined as remission or low-disease activity with no medication changes at all visits. The influence of patient characteristics on the number of deferrable visits in patients with stable disease was explored in four criteria sets that were based on: early disease duration, medication prescribed, presence of care complexity elements, and comorbidity burden. RESULTS: Records from 770 visits were reviewed from 365 RA patients (71.5% female, 70.0% seropositive). Among all criteria sets, the proportion of visits that could be redirected varied between 2.5%-20.9%. The highest proportion of deferrable visits was achieved when eligibility criteria included only stable disease activity and RA patients on conventional synthetic disease modifying drugs or no medications (n=161, 20.9%). CONCLUSION: PIFU may result in a more efficient use of specialist healthcare resources. However, the applicability of such models of care and the number of deferred visits is highly dependent on patient characteristics used to establish eligibility criteria for that model. These findings should be considered when planning implementation trials.

Content validity testing of the INTERMED Self-Assessment in a sample of adults with rheumatoid arthritis and rheumatology healthcare providers.

BACKGROUND: Care complexity can occur when patients experience health challenges simultaneously with social barriers including food and/or housing insecurity, lack of transportation or other factors that impact care and patient outcomes. People with rheumatoid arthritis (RA) may experience care complexity due to the chronicity of their condition and other biopsychosocial factors. There are few standardised instruments that measure care complexity and none that measure care complexity specifically in people with RA. OBJECTIVES: We assessed the content validity of the INTERMEDS Self-Assessment (IMSA) instrument that measures care complexity with a sample of adults with RA and rheumatology healthcare providers (HCPs). Cognitive debriefing interviews utilising a reparative framework were conducted. METHODS: Patient participants were recruited through two existing studies where participants agreed to be contacted about future studies. Study information was also shared through email blasts, posters and brochures at rheumatology clinic sites and trusted arthritis websites. Various rheumatology HCPs were recruited through email blasts, and divisional emails and announcements. Interviews were conducted with nine patients living with RA and five rheumatology HCPs. RESULTS: Three main reparative themes were identified: (1) Lack of item clarity and standardisation including problems with item phrasing, inconsistency of the items and/or answer sets and noninclusive language; (2) item barrelling, where items asked about more than one issue, but only allowed a single answer choice; and (3) timeframes presented in the item or answer choices were either too long or too short, and did not fit the lived experiences of patients. Items predicting future healthcare needs were difficult to answer due to the episodic and fluctuating nature of RA. CONCLUSIONS: Despite international use of the IMSA to measure care complexity, patients with RA and rheumatology HCPs in our setting perceived that it did not have content validity for use in RA and that revision for use in this population under a reparative framework was unfeasible. Future instrument development requires an iterative cognitive debriefing and repair process with the population of interest in the early stages to ensure content validity and comprehension. PATIENT OR PUBLIC CONTRIBUTION: Patient and public contributions included both patient partners on the study team and people with RA who participated in the study. Patient partners were involved in study design, analysis and interpretation of the findings and manuscript preparation. Data analysis was structured according to emergent themes of the data that were grounded in patient perspectives and experiences.

"How are you?" Perspectives From Patients and Health Care Providers of Text Messaging to Support Rheumatoid Arthritis Care: A Thematic Analysis.

OBJECTIVE: Patients with rheumatoid arthritis (RA) may need to access rheumatology care between scheduled visits. WelTel is a virtual care platform that supports secure two-way text-messaging between patients and their health care team. The objective of the present study was to explore perspectives and experiences of health care providers (HCPs) and patients related to the use of WelTel as an adjunct to routine care. METHODS: Seventy patients with RA were enrolled in a six-month WelTel pilot project launched in September 2021. Patients received monthly "How are you?" text message check-ins and could message their health care team during clinic hours to request health advice. The current project is a qualitative study of the WelTel pilot. A subgroup of pilot participants was purposively sampled and invited to participate in interviews. A thematic analysis of transcripts was conducted using a deductive approach leveraging quality of care domains. RESULTS: Thirteen patients (62% female, mean age 62 years, 10 White) completed interviews. Patients' views suggested that text messaging with the rheumatology team supported high-quality care across multiple quality domains including patient-centeredness, timeliness, efficiency, safety, effectiveness, equity, and appropriateness. Seven HCPs (57.1% female, one pharmacist and six rheumatologists) completed interviews. HCPs' perspectives varied based on their experience with the WelTel platform. Additional themes reported by HCPs included perceived increased workload and burnout. CONCLUSIONS: Patients with RA perceived text-based messaging as supporting high-quality care. The impact of increased communications on HCP burnout and workload requires consideration, and future studies should evaluate the effect of texting on patient outcomes.

The Evaluation of Guideline Quality in Rheumatic Diseases.

We evaluated the quality of selected rheumatology guidelines using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument. Guidelines were also assessed to determine if Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology had been used during development and for the inclusion of health inequity considerations. Only half of the guidelines used the GRADE methodology, and this was associated with higher AGREE II ratings in the Rigor of Development domain. Ongoing areas identified for improvement included more meaningful engagement of patients in guideline panels, increased transparency of the management of conflicts of interest, improved reporting of strategies for guideline implementation, and increased consideration of the health equity implications throughout guideline development and implementation.

Development and testing of the rheumatoid arthritis quality of care survey.

OBJECTIVES: The Rheumatoid Arthritis (RA) Quality of Care Survey (RAQCS) was developed to measure care quality according to a previously developed national RA quality improvement framework. METHODS: The development of the RAQCS occurred over 3 phases. First, the survey was developed by a team of healthcare providers, researchers, and two patient partners based on the existing national quality framework's 21 performance measures (PMs) and strategic objectives. Second, cognitive debriefing interviews were conducted with individuals living with RA to identify survey clarity, appropriateness of survey questions, and response options. Third, the survey was revised and distributed to participants recruited from Rheum4U (rheumatology longitudinal cohort). Results were tabulated and compared with a chart audit of participant medical records. RESULTS: Fifty-three participants completed the RAQCS. High performance (i.e., ≥70% meeting PM) was observed for 13 of 20 PMs. Lower performance was seen for the remaining PMs, which included documentation of body mass index (BMI) and smoking status, discussion of physical activity goals, comorbidity management including risk assessments for cardiovascular health and fragility fractures and disease activity assessment. There was high agreement (≥70%) between the RAQCS and chart review for 9 of 20 PMs. CONCLUSIONS: High agreement was observed between the RAQCS and chart review for selected PMs. The RAQCS may also be a valuable tool for quality improvement for measures where data are not usually available through other sources. Further testing of the RAQCS is needed to ascertain its reliability and validity as a patient self-reported tool to measure RA care quality.
