- OBJECTIVES: Type I IFN (IFN-I) activation is a prominent feature of primary SS (pSS), SLE, and SSc. Ultrasensitive single-molecule array (Simoa) technology has facilitated the measurement of subfemtomolar concentrations of IFNs. Here, we aimed to measure IFNα2 in serum from pSS, SLE, and SSc using a Simoa immunoassay and correlate these levels to blood IFN-stimulated gene (ISG) expression and disease activity.METHODS: Serum IFNα2 was measured in patients with pSS (n = 85; n = 110), SLE (n = 24), and SSc (n = 23), and healthy controls (HC; n = 68) using an IFNα Simoa assay on a HD-X analyser. IFN-I pathway activation was additionally determined from serum by an IFN-I reporter assay and paired samples of whole blood ISG expression of IFI44, IFI44L, IFIT1, IFIT3, and MxA by RT-PCR or MxA-ELISA.RESULTS: Serum IFNα2 levels were elevated in pSS (median=61.3 fg/mL) compared to HC (median ≤5 fg/mL; p < 0.001) and SSc (median=11.6 fg/mL; p = 0.043), lower compared to SLE (median=313.5 fg/mL; p = 0.068), and positively correlated with blood ISG expression (r = 0.66-0.94; p < 0.001). Comparable to MxA-ELISA (AUC=0.93), IFNα2 measurement using Simoa identified pSS with high ISG expression (AUC=0.90) with 80-93% specificity and 71-84% sensitivity. Blinded validation in an independent pSS cohort yielded a comparable accuracy. Multiple regression indicated independent associations of autoantibodies, IgG, HCQ treatment, cutaneous disease and history of extraglandular manifestations with serum IFNα2 concentrations in pSS.CONCLUSION: Thus, Simoa serum IFNα2 reflects blood ISG expression in pSS, SLE, and SSc. In light of IFN-targeting treatments, Simoa could potentially be applied for patient stratification or retrospective analysis of historical cohorts.

- Objective: To investigate whether food literacy competencies and diet quality vary between 16-to-24-year-olds vegans, lacto-ovo vegetarians, pescatarians, flexitarians and omnivores and to assess whether food literacy is associated with diet quality. Design: Cross-sectional study. Food literacy (general nutrition knowledge, critical nutrition literacy and food skills) and diet quality were measured using an electronic questionnaire. Setting: Southern Norway, September 2021 - March 2022. Participants: Healthy 16-24-year-olds (n 165). Results: Overall, the mean general nutrition knowledge score was moderate (480 out of 670); the lowest mean score was found in omnivores and the highest in flexitarians (456 v. 515) (P= 0034). The mean score of critical nutrition literacy was also moderate (37 out of 50); vegans showed higher scores compared to other dietary practices (P = 0018). No difference was observed in food skills between the different dietary practices. The overall median diet quality score was 460 out of 800, lowest in omnivores and highest in vegans (420 v. 560) (P=< 0001). In multivariate regression analyses, general nutrition knowledge, food skills and vegan dietary practice were significantly associated with higher diet quality. Conclusions: We found moderate levels of food literacy across all dietary practices. The food literacy competencies, general nutrition knowledge and food skills were associated with higher diet quality in our sample. Omnivores showed both the lowest general nutrition knowledge level and lowest diet quality scores. In contrast, both flexitarians and vegans scored highest on general nutrition knowledge and diet quality scores, despite being one of the less restrictive and one of the strictest plant-based dietary practices, respectively.

- Digital innovations in mental health offer great potential, but present unique challenges. Using a consensus development panel approach, an expert, international, cross-disciplinary panel met to provide a framework to conceptualise digital mental health innovations, research into mechanisms and effectiveness and approaches for clinical implementation. Key questions and outputs from the group were agreed by consensus, and are presented and discussed in the text and supported by case examples in an accompanying appendix. A number of key themes emerged. (1) Digital approaches may work best across traditional diagnostic systems: we do not have effective ontologies of mental illness and transdiagnostic/symptom-based approaches may be more fruitful. (2) Approaches in clinical implementation of digital tools/interventions need to be creative and require organisational change: not only do clinicians and patients need training and education to be more confident and skilled in using digital technologies to support shared care decision-making, but traditional roles need to be extended, with clinicians working alongside digital navigators and non-clinicians who are delivering protocolised treatments. (3) Designing appropriate studies to measure the effectiveness of implementation is also key: including digital data raises unique ethical issues, and measurement of potential harms is only just beginning. (4) Accessibility and codesign are needed to ensure innovations are long lasting. (5) Standardised guidelines for reporting would ensure effective synthesis of the evidence to inform clinical implementation. COVID-19 and the transition to virtual consultations have shown us the potential for digital innovations to improve access and quality of care in mental health: now is the ideal time to act.
