Glomeruli are highly sophisticated filters and glomerular disease is the leading cause of kidney failure. Morphological change in glomerular podocytes and the underlying basement membrane are frequently observed in disease, irrespective of the underlying molecular etiology. Standard electron microscopy techniques have enabled the identification and classification of glomerular diseases based on two-dimensional information, however complex three-dimensional ultrastructural relationships between cells and their extracellular matrix cannot be easily resolved with this approach. We employed serial block face-scanning electron microscopy to investigate Alport syndrome, the commonest monogenic glomerular disease, and compared findings to other genetic mouse models of glomerular disease ( Myo1e− / −, Ptpro− / − ). These analyses revealed the evolution of basement membrane and cellular defects through the progression of glomerular injury. Specifically we identified sub-podocyte expansions of the basement membrane with both cellular and matrix gene defects and found a corresponding reduction in podocyte foot process number. Furthermore, we discovered novel podocyte protrusions invading into the glomerular basement membrane in disease and these occurred frequently in expanded regions of basement membrane. These findings provide new insights into mechanisms of glomerular barrier dysfunction and suggest that common cell-matrix-adhesion pathways are involved in the progression of disease regardless of the primary insult.

IntroductionA core screening, assessment and outcome set is needed in cancer prehabilitation to standardise what is measured in both research and services. Currently, there is significant variation in measures used, which limits comparability between studies and evidence synthesis. Standardising measures will improve the quality, comparability and impact of research by reducing heterogeneity between studies, minimising reporting bias, improving trial efficiency, enabling data synthesis into large datasets, supporting international collaboration and data sharing, and accelerating the implementation of best practices.Methods and analysisAn international Delphi consensus process will be conducted involving patients, healthcare professionals and researchers to identify screening, assessment and outcomes and their corresponding measurement instruments, to be included in a core set. The study consists of three phases: (1) A scoping review to identify screening, assessment and outcomes and associated measurement instruments currently used in cancer prehabilitation. (2) At least two rounds of a modified Delphi survey to prioritise the identified screening, assessment and outcomes using a 1–9 Likert scale. Consensus will be defined across stakeholder groups using prespecified thresholds. A consensus meeting will be held if agreement is not reached. (3) Measurement instruments corresponding to each retained screening, assessment and outcome will be assessed for quality for measurement properties and feasibility. Further Delphi rounds will be conducted to reach consensus on the most appropriate measurement instrument for each core screening, assessment and outcome.Ethics and disseminationThe study has ethical approval (Ref: 25/NW/0159). Findings will be disseminated through peer-reviewed publications, conference presentations, stakeholder networks and made publicly available via the Core Outcome Measures in Effectiveness Trials database.

ObjectiveTo quantify how well phase III randomised clinical trials in both SLE and lupus nephritis (LN) represents a real-world SLE cohort.MethodsLiterature reviews were performed of major published phase III SLE (n=12) and LN (n=6) clinical trials (ClinicalTrials.gov). Inclusion and exclusion criteria common across these trials were collated for non-renal SLE or LN trials, and applied to patients recruited to the British Isles Lupus Assessment Group-Biologics Register (BILAG-BR) starting either biological or standard-of-care (SOC) therapies.ResultsWe recruited 837 patients to the BILAG-BR from September 2010 to June 2018, starting either SOC (n=125, 15%) or a biological medication (n=712, 85%). Active LN, defined as a BILAG A in the renal domain occurred in 20% (n=166). Overall, 530 (63%) patients were ineligible to participate in non-renal SLE clinical trials and 72 (43%) patients with active LN would be ineligible for LN trials. The most common reasons for ineligibility from the non-renal lupus trials included active renal involvement (n=166, 20%) and low disease activity (n=114, 15%). For LN trials, the most common exclusion met was pre-existing renal impairment (n=15, 9%). Patients with fewer comorbidities were more likely to be eligible to participate in non-renal SLE trials.ConclusionsIn this national register of patients with moderate-to-severe SLE, nearly two-thirds would not be eligible for recruitment to key SLE clinical trials nor would almost half of those with active LN. Eligibility criteria may excessively constrain enrolment and thus, how we can generalise trial results in a real-world setting.

Treatment of giant-cell arteritis with tocilizumab, an interleukin-6 receptor alpha inhibitor, while prednisone was tapered over a 26-week period resulted in higher rates of sustained remission than prednisone tapering plus placebo and reduced the total prednisone dose.

Background Patients with giant cell arteritis (GCA) treated with tocilizumab (TCZ) every week or every other week and prednisone tapering achieved superior rates of sustained remission to patients treated with placebo and prednisone tapering in a randomised controlled trial. Health-related quality of life (HRQOL) in patients from this trial is now reported. Methods Exploratory analyses of SF-36 PCS and MCS and domain scores, PtGA and FACIT-Fatigue were performed in patients treated with weekly subcutaneous TCZ 162 mg plus 26-week prednisone taper (TCZ-QW + Pred-26) or placebo plus 26-week or 52-week prednisone tapers (PBO + Pred-26 or PBO + Pred-52). These analyses were performed on responder and non-responder patients, including those who achieved the primary outcome and those who experienced flare and received escape prednisone doses. Results Baseline SF-36 PCS, MCS and domain scores were low, indicating impaired HRQOL related to GCA. At week 52, least squares mean (LSM) changes in PCS scores improved with TCZ-QW + Pred-26 but worsened in both PBO + Pred groups ( p  <  0.001). LSM changes in MCS scores increased with TCZ-QW + Pred-26 versus PBO + Pred-52 ( p  < 0.001). Treatment with TCZ-QW + Pred-26 resulted in significantly greater improvement in four of eight SF-36 domains compared with PBO + Pred-26 and six of eight domains compared with PBO + Pred-52 ( p  < 0.01). Improvement with TCZ-QW + Pred-26 met or exceeded minimum clinically important differences (MCID) in all eight domains compared with five domains with PBO + Pred-26 and none with PBO + Pred-52. Domain scores in the TCZ-QW + Pred-26 group at week 52 met or exceeded age- and gender-matched normative values (A/G norms). LSM changes from baseline in FACIT-Fatigue scores increased significantly with TCZ-QW + Pred-26, exceeding MCID and A/G norms ( p  < 0.001). Conclusions Patients with GCA receiving TCZ-QW + Pred-26 reported statistically significant and clinically meaningful improvement in SF-36 and FACIT-Fatigue scores compared with those receiving prednisone only. Improvements in the TCZ-QW + Pred-26 group led to recovery of HRQOL to levels at least comparable to those of A/G-matched normative values at week 52 and exceeded normative values in five of eight domains.

STAMINA is a randomised controlled trial of a complex lifestyle intervention incorporating exercise prescription into a prostate cancer care pathway. The 12-month intervention aims to improve disease specific quality of life and reduce fatigue of people receiving androgen deprivation therapy for prostate cancer. Previously published work outlines the development of the trial intervention which included recruitment and training of healthcare professionals and exercise professionals to embed a lifestyle intervention and referral pathway within NHS prostate cancer care. A mixed-methods process evaluation, embedded within the STAMINA trial, will be conducted to assess quantitative process outcomes (recruitment, intervention reach, dose and fidelity), together with up to 45 qualitative interviews with patients, healthcare professionals and exercise professionals. Interviews will explore the perceptions and experiences of those involved in the STAMINA trial, and the organisational implications of embedding and sustaining the intervention. Quantitative process data will be analysed descriptively. Qualitative interview data will be analysed before trial outcomes are known using an inductive and deductive approach. Findings from the different elements will be reported separately and then integrated to inform interpretation of trial outcomes. This process evaluation protocol provides a detailed description of relevant data collection methods and trial processes of the STAMINA randomised controlled trial which will allow us to determine whether the intervention can be delivered with fidelity, is acceptable to patients, healthcare professionals and exercise professionals, and understand the implications for embedding and sustaining the intervention in the routine care.

Background Adjuvant endocrine therapy (AET) reduces breast cancer recurrence and mortality. However, up to three quarters of women with breast cancer do not take AET as prescribed. Existing interventions to support adherence have shown limited effectiveness and often do not target the range of barriers to appropriate AET use. We developed four intervention components targeting barriers to AET adherence: Short Message Service (SMS) messages targeting forgetfulness, an information leaflet targeting medication beliefs, a self-management website targeting side-effects, and an acceptance and commitment therapy-based guided self-help programme targeting psychological flexibility. In the preparation phase of the Multiphase Optimisation Strategy (MOST), we conducted an external pilot optimisation trial. We met predefined progression criteria regarding consent, component adherence and availability of outcome measures, and concluded progression to an optimisation randomised controlled trial (O-RCT) was warranted. Our primary aim is to optimise the intervention package to support adherence to AET in women with early-stage breast cancer. Methods We will conduct a multi-centre, individually randomised superiority O-RCT using a 2 4 factorial design, with nested mixed-methods process and economic evaluations. We will randomise 512 women with early-stage breast cancer who have been prescribed AET to one of sixteen experimental conditions, operationalised as factors with two levels (on/off). Each condition is comprised of unique combinations of the intervention components. All participants will receive usual care. Our primary outcome is self-reported medication adherence at 12 months post-randomisation. Key secondary and process outcomes include quality of life, self-efficacy, habit formation, medication beliefs, psychological flexibility and distress, completed at 4, 8 and 12 months post-randomisation. Within the process evaluation, semi-structured interviews with participants will be conducted 5 and 13 months post-randomisation, and with trial therapists following intervention delivery. Cost per incremental quality-adjusted life year will be estimated in a health economic evaluation. Discussion Within the optimisation phase of the MOST framework, this trial, using a complex factorial design, will enable us to build a more effective, affordable, scalable and efficient intervention package to support AET adherence in women with breast cancer. This approach will advance intervention science by simultaneously testing the mechanisms through which the intervention components are operating.

IntroductionWomen with breast cancer who do not adhere to adjuvant endocrine therapy (AET) have increased risks of mortality and recurrence. There are multiple barriers to AET adherence, including medication side-effects, beliefs about medication, memory and psychological distress. We developed four intervention components, each targeting a different barrier. This pilot trial is part of the preparation phase of the Multiphase Optimisation Strategy, and aims to establish key trial parameters, establish intervention component adherence, establish availability and feasibility of outcome and process data, estimate variability in planned outcome measures and estimate cost of developing and delivering each intervention component.Methods and analysisThe four intervention components are as follows: short message service text reminders (target: memory); a written information leaflet (target: medication beliefs); a guided self-help Acceptance and Commitment Therapy programme (target: psychological flexibility to reduce distress) and a self-management website (target: side-effect management). To evaluate the feasibility of recruitment, acceptability of the intervention components and the availability of outcome data, we will conduct a multisite, exploratory pilot trial using a 24-1 fractional factorial design, with a nested process evaluation. We will randomise 80 women with early-stage breast cancer who have been prescribed AET to one of eight experimental conditions. This will determine the combination of intervention components they receive, ranging from zero to four, with all conditions receiving usual care. Key outcomes of interest include medication adherence and quality of life. Progression to the optimisation phase will be based on predefined criteria for consent rates, patient adherence to intervention components and availability of medication adherence data.Ethics and disseminationThe study was reviewed by the Wales Research Authority Research Ethics Committee 3 (21/WA/0322). Written informed consent will be obtained from all patients before randomisation. The results of this trial will be disseminated in a peer-reviewed journal.Trial registration numberISRTCN10487576.
