An exploration of factors involved in the roll out of a digital application in breast services: A case study approach.

Acceptance of new technologies in health care, by those who use them as part of their role, is challenging with confounding contextual factors surrounding the acceptance of technology. As healthcare is rapidly digitising, stakeholder groups should be included in each stage of evaluation and implementation to allow opportunities to influence and contribute to digital health policies. This research employed a case study methodology to initiate an exploration into the factors associated with implementing a digital application into a mammography service. It examined the initial implementation and subsequent impact of the rollout of a digital application (VA) within a breast service in South Australia. Stakeholders' opinions on team performance and feedback mechanisms of the digital application were evaluated through a staff questionnaire distributed through an online survey JISC. The incorporation of digitised technology into a service is evidently met with challenges. Although there is potential value in utelising automated feedback for workflow improvement and patient services, it appears imperative to provide targeted and developmental resources for educational development and staff well-being during the implementation phase. This case study approach delves into key discussion areas and serves as the initial insight into the implementation of a digital application. It could be regarded as a foundational reference for future evaluations of digital applications. Research around digital fluency within the radiography profession requires further consideration. Under-utilisation or resistance may result in missed opportunities to enhance patient experiences and care outcomes and support staff wellbeing. Therefore, continued engagement and the encouragement of user feedback during the implementation phase are crucial to demonstrate future acceptance of digital applications in clinical settings.

Symptom-based stratification of patients with primary Sjögren's syndrome: multi-dimensional characterisation of international observational cohorts and reanalyses of randomised clinical trials

Background Heterogeneity is a major obstacle to developing effective treatments for patients with primary Sjögren's syndrome. We aimed to develop a robust method for stratification, exploiting heterogeneity in patient-reported symptoms, and to relate these differences to pathobiology and therapeutic response. Methods We did hierarchical cluster analysis using five common symptoms associated with primary Sjögren's syndrome (pain, fatigue, dryness, anxiety, and depression), followed by multinomial logistic regression to identify subgroups in the UK Primary Sjögren's Syndrome Registry (UKPSSR). We assessed clinical and biological differences between these subgroups, including transcriptional differences in peripheral blood. Patients from two independent validation cohorts in Norway and France were used to confirm patient stratification. Data from two phase 3 clinical trials were similarly stratified to assess the differences between subgroups in treatment response to hydroxychloroquine and rituximab. Findings In the UKPSSR cohort (n=608), we identified four subgroups: Low symptom burden (LSB), high symptom burden (HSB), dryness dominant with fatigue (DDF), and pain dominant with fatigue (PDF). Significant differences in peripheral blood lymphocyte counts, anti-SSA and anti-SSB antibody positivity, as well as serum IgG, κ-free light chain, β2-microglobulin, and CXCL13 concentrations were observed between these subgroups, along with differentially expressed transcriptomic modules in peripheral blood. Similar findings were observed in the independent validation cohorts (n=396). Reanalysis of trial data stratifying patients into these subgroups suggested a treatment effect with hydroxychloroquine in the HSB subgroup and with rituximab in the DDF subgroup compared with placebo. Interpretation Stratification on the basis of patient-reported symptoms of patients with primary Sjögren's syndrome revealed distinct pathobiological endotypes with distinct responses to immunomodulatory treatments. Our data have important implications for clinical management, trial design, and therapeutic development. Similar stratification approaches might be useful for patients with other chronic immune-mediated diseases.

Effectiveness of orally administered co-enzyme Q10 for schizophrenia: cognitive, functional and biochemical outcomes from a double blind, randomised, placebo controlled trial

Coenzyme Q10 (CoQ10) is an endogenous compound that is essential for energy production within the mitochondria and also functions as a potent anti-oxidant, inhibiting oxidative stress and damage. Often deficits in CoQ10 are associated with fatigue, and cognitive and psychological impairment. In light of its many functions, CoQ10 supplementation to minimise decline and improve symptoms has been investigated in multiple disorders including neurological and neuropsychiatric disorders, with results indicating positive effects on fatigue, cognitive impairment and affective difficulties for disorders such as bipolar disorder and chronic fatigue syndrome. There is also evidence of mitochondrial dysfunction in schizophrenia. In light of this evidence, the current study aimed to investigate the potential effect of CoQ10 supplementation on 1) cognitive function and 2) psychological and physical health in schizophrenia and schizoaffective disorder

No Effect of Coenzyme Q10 on Cognitive Function, Psychological Symptoms, and Health-related Outcomes in Schizophrenia and Schizoaffective Disorder: Results of a Randomized, Placebo-Controlled Trial

BACKGROUND: Cognitive impairments, negative symptoms, affective symptoms, and low energy are highly prevalent features of schizophrenia. Mitochondrial dysfunction has been hypothesized as one of the numerous factors to underlie the manifestation of these symptoms. The objective of this study was to evaluate whether Coenzyme Q10 (CoQ10) has a role in the treatment of schizophrenia and schizoaffective disorder. METHODS: A double-blind, randomized, placebo-controlled trial was conducted to assess the effects of CoQ10 supplementation (300 mg/day) on the co-primary outcomes of attention and working memory performance after 3 and 6 months. Secondary outcomes included plasma CoQ10 levels, mitochondrial function, energy, depression, anxiety, negative symptoms, and quality oflife. FINDINGS: In total, 72 patients were randomized to intervention groups. Overall, there was no effect of CoQ10 supplementation on the primary outcome measures at 3 or 6 months. Further, with the exception of plasma CoQ10 levels, CoQ10 supplementation also had no effect on the secondary outcomes. At 3 months, CoQ10 concentration was significantly higher in the CoQ10 group (3.85 μg/mL) compared with placebo (1.13 μg/mL); this difference was not present at 6 months. CONCLUSIONS: The results of the study suggest that CoQ10 supplementation at 300 mg/day for 6 months is unlikely to be beneficial for cognitive, psychological and health-related outcomes in schizophrenia and schizoaffective disorder. However, a number of limitations including low adherence, modest sample size, and attrition, likely reduce estimates of effects. As such, results should be considered preliminary
