There is a strong association between total hip bone mineral density (THBMD) changes after 24 mo of treatment and reduced fracture risk. We examined whether changes in THBMD after 12 and 18 mo of treatment are also associated with fracture risk reduction. We used individual patient data (n = 122 235 participants) from 22 randomized, placebo-controlled, double-blind trials of osteoporosis medications. We calculated the difference in mean percent change in THBMD (active-placebo) at 12, 18, and 24 mo using data available for each trial. We determined the treatment-related fracture reductions for the entire follow-up period, using logistic regression for radiologic vertebral fractures and Cox regression for hip, non-vertebral, all (combination of non-vertebral, clinical vertebral, and radiologic vertebral) fractures and all clinical fractures (combination of non-vertebral and clinical vertebral). We performed meta-regression to estimate the study-level association (r2 and 95% confidence interval) between treatment-related differences in THBMD changes for each BMD measurement interval and fracture risk reduction. The meta-regression revealed that for vertebral fractures, the r2 (95% confidence interval) was 0.59 (0.19, 0.75), 0.69 (0.32, 0.82), and 0.73 (0.33, 0.84) for 12, 18, and 24 mo, respectively. Similar patterns were observed for hip: r2 = 0.27 (0.00, 0.54), 0.39 (0.02, 0.63), and 0.41 (0.02, 0.65); non-vertebral: r2 = 0.27 (0.01, 0.52), 0.49 (0.10, 0.69), and 0.53 (0.11, 0.72); all fractures: r2 = 0.44 (0.10, 0.64), 0.63 (0.24, 0.77), and 0.66 (0.25, 0.80); and all clinical fractures: r2 = 0.46 (0.11, 0.65), 0.64 (0.26, 0.78), and 0.71 (0.32, 0.83), for 12-, 18-, and 24-mo changes in THBMD, respectively. These findings demonstrate that treatment-related THBMD changes at 12, 18, and 24 mo are associated with fracture risk reductions across trials. We conclude that BMD measurement intervals as short as 12 mo could be used to assess fracture efficacy, but the association is stronger with longer BMD measurement intervals.

ObjectiveDiabetic foot ulcers (DFUs) present a significant global health challenge, resulting in high morbidity and economic costs. Current available treatments often fail to achieve satisfactory healing rates, highlighting the need for novel therapies. This study evaluated the safety and efficacy of a novel autologous whole blood clot (AWBC)-a blood-based, biodegradable provisional matrix-in conjunction with standard of care (SoC) when compared to SoC alone in the treatment of hard-to-heal DFUs.MethodA multicentre, prospective, blinded assessor, randomised controlled trial was conducted at 16 sites across the US, South Africa and Turkey. A cohort of patients with hard-to-heal DFUs was enrolled and randomised to either the AWBC group or the control group. The primary endpoint was complete wound closure at 12 weeks, while secondary endpoints included time to heal and percentage area reduction (PAR) at four and eight weeks. Data were analysed using both intention-to-treat (ITT) and per-protocol (PP) populations.ResultsThe cohort included 119 patients. AWBC treatment resulted in a significantly higher healing rate compared to the control in both ITT (41% versus 15%, respectively; p=0.002) and PP populations (51% versus 18%, respectively; p=0.0075). AWBC treatment also resulted in a shorter mean time to heal and higher durability of wound closure. Safety analysis showed a similar incidence of adverse events (AEs) between groups, with no device-related AEs.ConclusionThe AWBC system, by modulating the wound microenvironment and providing a functional extracellular matrix, offered a promising new approach to treating hard-to-heal DFUs, demonstrating superior healing outcomes compared to SoC alone in this study.

MEDICAL sciences , *RANDOMIZED controlled trials , *VISUAL analog scale , *KNEE pain , *RANGE of motion of joints - Abstract
Background: Patellofemoral pain (PFP) is a common musculoskeletal disorder resulting in anterior knee pain. Physiotherapy is the current standard treatment, while surgical intervention (tibial tubercle transfer [TTT]) is reserved for chronic cases when nonoperative treatment has failed. TTT can result in clinically meaningful improvement in patients with patellofemoral maltracking without instability. However, to date, no randomised controlled trials (RCT) have compared TTT combined with a physiotherapy (PT) programme to PT alone as the initial treatment for PFP. Methods: A single-centre nonblinded RCT in 40 patients with chronic PFP (> 1 year) and tibial tubercle-trochlear groove (TT-TG) > 15 mm will be randomised to either TTT followed by PT or to PT alone in a 1:1 ratio in a concealed manner. The primary outcome is knee pain at 18 weeks for the TTT group (6 weeks splint phase + 12 weeks PT) and at 12 weeks for the PT group, measured by the visual analog scale (VAS). Secondary outcomes include Patient-Reported Outcome Measures (PROMs) using the Kujala score, International Knee Documentation Committee (IKDC) 'Subjective Knee Form', Tegner Activity score and EuroQol 5D-5 L for quality of life. Range of motion (ROM) is measured using the decline step-down test (DSDT). Between-group differences will be analysed using multivariable linear regression analysis, while longitudinal differences will be assessed with linear mixed models for repeated measures. The difference in direct medical costs will also be assessed. Discussion: The REVITALISE study is the first randomised study to compare surgical intervention (TTT) followed by PT to PT alone in patients with chronic PFP. This study will generate level-1 evidence on the most effective treatment for chronic PFP, which can be integrated into the national guideline to aid orthopaedic surgeons and physiotherapists in their decision-making and ultimately improve our care for patients with chronic PFP. Trial registration: Study Identifier NCT06227806, registered on 26 Jan 2024 on ClinicalTrials.gov. The study underwent independent peer review and received approval from the ethical review board (number NL80956.091.22). [ABSTRACT FROM AUTHOR]

SUICIDE prevention , *RANDOMIZED controlled trials , *SUICIDE statistics , *HELP-seeking behavior , *PUBLIC health - Abstract
Background: In Australia and internationally, it is men who predominately die by suicide. Men are less likely than women to seek help for their mental health difficulties and this may contribute to their higher suicide rates. We created a 4-minute music video encouraging Australian men to seek help for mental health difficulties (Boys Do Cry). We aimed to assess in a randomised controlled trial (RCT) whether the Boys Do Cry video increased men's intentions to seek help for mental health difficulties from baseline (T1) to post-intervention (1 week = T2). Methods: We conducted an online single-blind, two-arm RCT comparing the effects of Boys Do Cry against a control video. Analyses were undertaken on an intent-to-treat basis using linear mixed effects models with variables for trial arm, occasion of measurement and their interaction. Intervention effectiveness was assessed by comparing the mean difference between arms in change of the total score on the General Help-Seeking Questionnaire (GHSQ) from T1 to T2. Results: 476 participants were randomised (intervention = 243; control = 233). At T1, GHSQ means were similar (intervention = 45.28; control = 45.70). After viewing the videos, GHSQ means increased in both arms (intervention = 47.33; control = 46.59), with no evidence of a difference in scores at T2 (modelled mean difference = 0.62, 95% CI -1.11 to 2.35, p = 0.485). Similar results were observed for all secondary outcomes. No adverse events were observed. Conclusions: Boys Do Cry demonstrated some evidence of a positive effect on help-seeking intentions among Australian men; however, so too did the control video, and no significant difference was observed.

Background: Blinding is essential for mitigating biases in trials of low back pain (LBP). Our main objectives were to assess the feasibility of blinding: (1) participants randomly allocated to active or placebo spinal manual therapy (SMT), and (2) outcome assessors. We also explored blinding by levels of SMT lifetime experience and recent LBP, and factors contributing to beliefs about the assigned intervention. Methods: A two-parallel-arm, single-centre, placebo-controlled, blinding feasibility trial. Adults were randomised to active SMT (n = 40) or placebo SMT (n = 41). Participants attended two study visits for their assigned intervention, on average seven days apart. The primary outcome was participant blinding (beliefs about assigned intervention) using the Bang blinding index (BI) at two study visits. The Bang BI is arm-specific, chance-corrected, and ranges from − 1 (all incorrect beliefs) to 1 (all correct beliefs), with 0 indicating equal proportions of correct and incorrect beliefs. Secondary outcomes included factors contributing to beliefs about the assigned intervention. Results: Of 85 adults screened, 81 participants were randomised (41 [51%] with SMT lifetime experience; 29 [39%] with recent LBP), and 80 (99%) completed follow-up. At study visit 1, 50% of participants in the active SMT arm (Bang BI: 0.50 [95% confidence interval (CI), 0.26 to 0.74]) and 37% in the placebo SMT arm (0.37 [95% CI, 0.10 to 0.63]) had a correct belief about their assigned intervention, beyond chance. At study visit 2, BIs were 0.36 (0.08 to 0.64) and 0.29 (0.01 to 0.57) for participants in the active and placebo SMT arms, respectively. BIs among outcome assessors suggested adequate blinding at both study visits (active SMT: 0.08 [− 0.05 to 0.20] and 0.03 [− 0.11 to 0.16]; placebo SMT: − 0.12 [− 0.24 to 0.00] and − 0.07 [− 0.21 to 0.07]). BIs varied by participant levels of SMT lifetime experience and recent LBP. Participants and outcome assessors described different factors contributing to their beliefs. Conclusions: Adequate blinding of participants assigned to active SMT may not be feasible with the intervention protocol studied, whereas blinding of participants in the placebo SMT arm may be feasible. Blinding of outcome assessors seemed adequate. Further methodological work on blinding of SMT is needed. Trial registration number: NCT05778396. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Breast cancer is the most diagnosed cancer in women worldwide and carries a considerable psychosocial burden. Interventions based on Acceptance and Commitment Therapy (ACT) and compassion-based approaches show promise in improving adjustment and quality of life in people with cancer. The Mind programme is an integrative ACT and compassion-based intervention tailored for women with breast cancer, which aims to prepare women for survivorship by promoting psychological flexibility and self-compassion. A pilot study of the Mind programme has shown acceptability and preliminary efficacy in improving quality of life and psychological health. This paper presents the study protocol of two randomised controlled trials that aim to test the efficacy and cost-effectiveness of an optimised version of the Mind programme in women with breast cancer. Methods: Participants will be women diagnosed with breast cancer randomly assigned to the Mind programme or a support group intervention (active control) in a 1:1 ratio for study 1, while study 2 includes one more arm (treatment as usual; inactive control) and a 2:2:1 ratio. Both interventions will be delivered weekly via an 8-session face-to-face or online group format. Data will be collected at baseline, post-treatment and 6-month follow-up. The efficacy and cost-effectiveness of the two interventions will be assessed. Treatment outcomes will comprise cancer-specific quality of life (primary outcome), anxiety and depressive symptoms, psychological flexibility, self-compassion, health-related quality of life, resource use, and intervention's acceptability and feasibility. Study 1 will also include immunological and epigenetic markers associated with breast cancer prognosis and mental health. Outcome assessors will be blind to group allocation. Statistical analyses will be conducted using an intention-to-treat approach. Analyses of moderators and mediators of change will also be performed. Discussion: These trials examine the efficacy and cost-effectiveness of an integrative ACT and compassion-based intervention tailored for women with breast cancer. Greater improvements in psychosocial, biological and resource use are expected in the Mind group, when compared to the control group(s). Results will likely support the potential benefits of the Mind programme for breast cancer patients and highlight the clinical relevance of integrative and holistic interventions in oncology.

- Abstract
Background: Smoking rates in the UK have declined steadily over the past decades, masking considerable inequalities, as little change has been observed among people with a mental health condition. This trial sought to assess the feasibility and acceptability of supplying an electronic cigarette (e-cigarette) starter kit for smoking cessation as an adjunct to usual care for smoking cessation, to smokers with a mental health condition treated in the community, to inform a future effectiveness trial. Methods: This randomised controlled feasibility trial, conducted March-December 2022, compared the intervention (e-cigarette starter kit with a corresponding information leaflet and demonstration with Very Brief Advice) with a 'usual care' control at 1-month follow-up. Participants were ≥ 18 years, receiving treatment for any mental health condition in primary or secondary care in three Mental Health Trusts in Yorkshire and one in London, UK. They were also willing to address their smoking through either cessation or reduction of cigarette consumption. The agreed primary outcome measure was feasibility (consent ~ 15% of eligible participants; attrition rate < 30%). Acceptability, validated sustained abstinence and ≥ 50% cigarette consumption reduction at 1-month, were also evaluated and qualitative interviews conducted to further explore acceptability in this population. Results: Feasibility targets were partially met; of 201 eligible participants, 43 (mean age = 45.2, SD = 12.7; 39.5% female) were recruited (21.4%) and randomised (intervention:48.8%, n = 21; control:51.2%, n = 22). Attrition rate was 37.2% at 1-month follow-up and was higher (45.5%) in the control group. At follow-up (n = 27), 93.3% (n = 14) in the intervention group and 25.0% (n = 3) in the control group reported e-cigarette use. The intervention was well received with minimal negative effects. In intention-to-treat analysis, validated sustained abstinence at 1-month was 2/21 (9.5%) and 0/22 (0%) and at least 50% reduction in cigarette consumption 13/21 (61.9%) and 3/22 (13.6%), for the intervention and control group, respectively. Qualitative analysis of participant interviews (N = 5) showed the intervention was broadly acceptable, but they also highlighted areas of improvements for the intervention and trial delivery. Conclusions: Offering an e-cigarette starter kit to smokers with a mental health condition treated in the community was acceptable and largely feasible, with harm reduction outcomes (i.e. switching from cigarette smoking to e-cigarette use and substantial reduction in cigarette consumption) favouring the intervention. The findings of the study will be used to help inform the design of a main trial. Trial Registration: Registry: ISRCTN. Registration number: ISRCTN17691451.

FECAL microbiota transplantation , *DIVERTICULITIS , *TREATMENT effectiveness , *COMPUTED tomography , *GUT microbiome - Abstract
Background: Little is known about the involvement of gut microbiota in the disease course of diverticulitis and the potential benefits of manipulating the gut milieu. We propose to conduct a randomised placebo-controlled feasibility trial of faecal microbiota transplantation (FMT) given as capsules to patients with acute uncomplicated diverticulitis. Objectives: The objective is primarily to investigate the feasibility of clinical safety, explore efficacy associated with FMT in this patient population, and examine changes in patient-reported quality of life and the composition and function of the gut microbiota. Design: Study protocol for a randomised placebo-controlled trial. Methods and analysis: Participants with acute, uncomplicated diverticulitis, as confirmed by computed tomography (CT) scan, will be recruited from Odense University Hospital (Denmark) and randomly assigned to either the intervention group or the control group. The intervention group will consist of 20 patients who receive encapsulated FMT. The control group will also consist of 20 patients, receiving placebo capsules. Primary safety endpoint : Patient safety is monitored by (a) the number of re-admissions and (b) the number of adverse events within 3 months of FMT/placebo; Primary efficacy endpoint : Reduction in the proportion of patients treated with antibiotics within 3 months following FMT/placebo; Secondary outcome : Change from baseline to 3 months in the GI-QLI questionnaire. Results will be analysed using an intention-to-treat approach. Adverse events or unintended consequences will be reported. Ethics and discussion: This is the first study to investigate the safety and efficacy of FMT in patients with acute uncomplicated diverticulitis. The project has the potential to broaden the knowledge and literature on the role of the intestinal microbiota in diverticulitis, and we believe it will elevate our understanding of cause and effect. Trial registration: Informed consent is obtained from all participants. The study is approved by the regional ethics committee (ref. S-20230023) and the Danish Data Protection Agency (ref. 24/2435). The trial was registered on clinicaltrials.gov (NCT06254625) on 10th February 2024. [ABSTRACT FROM AUTHOR]

Purpose Methods Results Conclusions To investigate 2‐year changes in macular choroidal thickness (ChT) in children receiving 0.01% atropine eyedrops and its relationship with spherical equivalent refraction (SER) progression and axial length (AL) elongation.A total of 250 myopic children aged 6–16 years (167%–0.01% atropine, 83‐placebo) were enrolled in the MOSAIC (ISRCTN36732601) clinical trial. Participants with complete 2‐year ChT (Topcon Triton Swept‐Source OCT), SER, and AL data were included in this study. Changes in macular ChT at 2 years and associations with changes in SER and AL elongation were analysed using linear mixed models.A total of 187 children (126%–0.01% atropine, 61‐placebo) were included in the analysis. Choroidal thickness over 2 years was stable in the 0.01% atropine compared with placebo group, which exhibited consistent thinning in subfoveal (mean ± SE: 0.49 ± 2.22 μm vs. −9.46 ± 2.69 μm; p = 0.034), parafoveal (1.40 ± 1.73 μm vs. −8.11 ± 2.08 μm; p = 0.002), and perifoveal (0.80 ± 1.25 vs. −6.17 ± 1.69; p = 0.002) macular subfields. Choroidal thickening was observed in participants with slower axial eye growth and myopia progression, regardless of their treatment group. Mediation analysis indicated that atropine 0.01% had a significant effect on ChT, with 68.3% of the effect being direct and 31.7% mediated through axial length changes. For SER, the direct effect on ChT was 80%, with the remaining 20% mediated by SER changes.Myopic participants treated with 0.01% atropine exhibited stable ChT over 2 years, whereas the placebo group showed consistent thinning. The effect of atropine 0.01% on ChT was only partially explained by axial length and SER changes, indicating a direct effect of atropine treatment on the choroid. [ABSTRACT FROM AUTHOR]

Background: Around 40% of people with major depressive disorder (MDD) experience moderate remission, with the remainder meeting the criteria for resistant major depression (RMD). It has been shown that exercise has a low-to-moderate effect on MDD, but there is a lack of evidence on exercise interventions in RMD patients. The primary purpose of the proposed study will be to investigate the effect of a 12-week supervised combined exercise program on depressive symptoms in people with RMD compared to a treatment-as-usual (TAU) group. Method: This randomised, single-blind, controlled experimental trial will include 70 adults (≥ 18 years old) with RMD. Participants randomised to an exercise intervention, or a TAU group will be assessed at baseline and after a three-month intervention period. The primary variable will be participants' depressive symptoms measured with the Montgomery-Asberg Depression Rating Scale. Secondary outcome variables will include cardiorespiratory fitness (peak oxygen uptake through peak cardiopulmonary exercise test), body composition (bioimpedance and anthropometric variables), physical activity level (the International Physical Activity Questionnaire), health-related quality of life (the Short Form-36 Health Survey), functional outcome (the Sheehan Disability Scale and Quality of Life in Depression Scale), overall disease severity (the Clinical Global Impression Scale-Severity of Illness), and biochemical variables (a fasting blood sample). Discussion: This study will try to answer whether a supervised co-adjuvant combined (aerobic and resistance training) exercise program will help the prognosis of this population with RMD.

PSYCHOTHERAPY , *SUICIDE prevention , *SUICIDE risk factors , *COGNITIVE therapy , *SUICIDAL ideation - Abstract
Background: Suicide is the leading cause of preventable death in prisons. Deaths from suicide in prison are significantly, and persistently, elevated compared to those living in the community. Psychological therapies have been shown to be a potentially effective means of alleviating suicidal thoughts, plans and behaviours, but patients located in prison often have no access to evidence-based psychological interventions targeting suicide. The objectives of this programme of research are to investigate the clinical and cost effectiveness of a new psychological therapy programme delivered to male prisoners at risk of suicide. Methods: The PROSPECT trial is a two-armed single blind, pragmatic, randomised controlled trial and will recruit a target sample size of 360 male prisoners, identified as at-risk of suicide, across 4 prisons in the North of England. Participants will be randomised to receive a psychological talking therapy (Cognitive Behavioural Suicide Prevention, CBSP) plus treatment as usual, or treatment as usual alone. Co-primary outcomes (Suicide Ideation and Suicide Behaviours), as well as related secondary outcomes, will be assessed at baseline and at 6-months follow-up. An intention to treat analysis will be conducted with primary stratification based on prison site and lifetime history of suicide attempt (yes/no). A nested qualitative process evaluation will investigate the nature and context in which the intervention is delivered, with specific focus upon the facilitators and barriers to the implementation of the therapy within prisons. Discussion: The key outputs from this trial will be to determine whether a psychological therapy for suicidal prisoners is clinically and cost effective; and to generate a project implementation platform that identifies how best to implement the new intervention across the broader prison estate. Trial registration: ISRCTN (reference ISRCTN14056534 https://www.isrctn.com/ISRCTN14056534; 24th September 2021). Registration confirmed prior to participant recruitment commencing.

Background: Cognitive impairment is common in haemodialysis patients with no known beneficial interventions. Cooler dialysate slows brain white-matter changes, but its effect on cognition is unknown. This feasibility trial was performed to inform a fully-powered, randomised trial to assess this. Methods: We aimed to randomise (1:1) 90 haemodialysis patients to this double-blinded, randomised controlled feasibility trial to standard care (dialysate-temperature 36.5 °C) or intervention (35 °C). Eligible patients were adult chronic haemodialysis recipients with no established diagnosis of dementia or psychiatric disease. The primary outcome was change in Montreal Cognitive Assessment (MoCA) score at 12-months. Secondary outcomes included recruitment and attrition rates, reasons for non-recruitment, intradialytic hypotension, depression, patient burden, computerised cognition test battery, and quality of life. Findings: Of 334 patients screened, 160 were eligible. 99 declined mainly for the extra non-dialysis day study visits. Sixty-one patients consented, 43 randomised – 20 in standard care, 23 in intervention arms; 13 withdrew for non-dialysis day visits and 5 without reason before randomisation. 27 patients (12 standard care, 15 intervention) completed the trial – 5 died, 1 transplanted, 4 withdrew consent, and 6 could not attend due to the pandemic. Low temperature dialysis was well tolerated. There was no difference in change in MoCA from baseline to 12 months between the standard and intervention arms; 1.0 (-2.8–3.0, p = 0.755) and − 2.0 (-1.0 - -4.0, p = 0.047) respectively. There were no differences between groups on any secondary measures. There were no significant adverse events reported. Discussion: The trial was significantly affected by the COVID-19 pandemic contributing to an attrition rate of 27%. The non-dialysis day research visits were mainly responsible for low recruitment and consent withdrawal. There are several learning points, described in the article, which will inform design of definitive trials in this area in the future. Trial registration: ClinicalTrials.gov Identifier NCT03645733.

The gut microbiome is impacted by certain types of dietary fibre. However, the type, duration and dose needed to elicit gut microbial changes and whether these changes also influence microbial metabolites remain unclear. This study investigated the effects of supplementing healthy participants with two types of non-digestible carbohydrates (resistant starch (RS) and polydextrose (PD)) on the stool microbiota and microbial metabolite concentrations in plasma, stool and urine, as secondary outcomes in the Dietary Intervention Stem Cells and Colorectal Cancer (DISC) Study. The DISC study was a double-blind, randomised controlled trial that supplemented healthy participants with RS and/or PD or placebo for 50 d in a 2 × 2 factorial design. DNA was extracted from stool samples collected pre- and post-intervention, and V4 16S rRNA gene sequencing was used to profile the gut microbiota. Metabolite concentrations were measured in stool, plasma and urine by high-performance liquid chromatography. A total of fifty-eight participants with paired samples available were included. After 50 d, no effects of RS or PD were detected on composition of the gut microbiota diversity (alpha- and beta-diversity), on genus relative abundance or on metabolite concentrations. However, Drichlet's multinomial mixture clustering-based approach suggests that some participants changed microbial enterotype post-intervention. The gut microbiota and fecal, plasma and urinary microbial metabolites were stable in response to a 50-d fibre intervention in middle-aged adults. Larger and longer studies, including those which explore the effects of specific fibre sub-types, may be required to determine the relationships between fibre intake, the gut microbiome and host health.

Background: People with severe mental illness experience physical health inequalities and a 15–20-year premature mortality rate. Forensic inpatients are particularly affected by restrictions on movement, long admissions, and obesogenic/sedative psychotropic medication. We aimed to establish the feasibility and acceptability of Motiv8, a multidisciplinary weight management intervention co-produced with service users for forensic inpatients. Methods: A randomised waitlist-controlled trial of Motiv8(+Treatment-As-Usual) vs.TAU was conducted in medium-secure forensic services in Greater Manchester. Motiv8 is a 9-week programme of exercise sessions, diet/cooking classes, psychology, physical health/sleep education, and peer support. Physical and mental health assessments were conducted at baseline/10-weeks/3-months. A nested qualitative study captured participant experiences. A staff sub-study explored ward environment. Results: We aimed to recruit 32 participants (four cohorts). The trial met recruitment targets (n=29, 90.9%; 4 cohorts, 100%), participants were randomised to Motiv8+TAU (n=12) or waitlist (control) (n=17). Acceptable retention rates were observed (93.1%, 10-weeks; 72.4%, 3-months), and participants engaged well with the intervention. The blind was maintained, and no safety concerns raised. Assessment completion was high suggesting acceptability (>90% for people retained and engaged in the study). Participants reported high levels of satisfaction. Conclusions: The trial was not powered to detect group differences. However, data suggests it is feasible to conduct a rigorous, methodologically robust study of Motiv8 vs.TAU for adults on forensic inpatient units. Motiv8 was acceptable with potential promise providing evidence to proceed to a definitive trial for males. A larger trial is needed to explore potential effectiveness and reduce physical health inequalities for people with SMI.

Background: In Norway, municipal acute wards (MAWs) were implemented as alternatives to hospitalisation. Evaluations of the quality of MAW services are lacking. The primary objective of this study was to compare patient experiences after admission to a MAW versus to a hospital. The secondary objective was to compare 'readmissions', 'length of stay', 'self-assessed health-related quality of life' as measured by the EuroQol 5 items 5 level (EQ-5D-5L) index, and 'health status' measured by the RAND-12, in patients admitted to a MAW versus a hospital. Methods: A multicentre randomised controlled trial (RCT), randomising patients to either MAW or hospital. Results: In total, 164 patients were enrolled in the study; 115 were randomised to MAW and 49 to hospital. There were no significant differences between the MAW and hospital groups regarding patient experience, which was rated positively in both groups. Patients in the MAW group reported significantly better physical health status as measured by the RAND-12 four to six weeks after admittance than those randomised to hospital (physical component summary score, 31.7 versus 27.1, p = 0.04). The change in EQ-5D index score from baseline to four to six weeks after admittance was significantly greater among patients randomised to MAWs versus hospitals (0.20 versus 0.02, p = 0.03). There were no other significant differences between the MAW and hospital groups. Conclusions: In this study, patient experiences and readmissions were similar, whether patients were admitted to a MAW or a hospital. The significant differences in health status and quality of life favouring the MAWs suggest that these healthcare services may be better for elderly patients. However, unfortunately we did not reach the planned sample size due to challenges in the data collection posed by the Covid-19 pandemic. KEY POINTS: Municipal acute wards have been implemented in Norway as alternatives to hospitalisation. However, the quality of these wards remains unexplored. Results in this study indicates that patient experiences after stays in municipal acute wards are equally positive to experiences after stays in hospital there are no significant differences in length-of-stay, readmission rates or mortality between municipal acute wards and hospital patients have slightly more positive self-rated health and health status 4–6 weeks after staying in a municipal acute ward [ABSTRACT FROM AUTHOR]

Background: Postmenopausal osteoporosis (PMOP) is a serious condition that affects elderly individuals. Our previous study revealed that Yigu decoction (YGD) effectively improved bone mineral density (BMD) in elderly individuals, but the mechanism underlying this effect remains unclear. In this study, we investigated the relationships among YGD, microRNAs (miRNAs), and bone metabolism by assessing the effects of YGD on the miRNA levels in patient plasma to provide a scientific basis for treating PMOP with YGD. Methods: In this clinical trial, 60 patients were randomly assigned to the YGD group or the control group (ratio of 1:1) and treated for 3 months. The primary outcome measure was BMD, and the secondary outcome measures included plasma miRNA levels, visual analogue scale (VAS) scores, alkaline phosphatase (ALP) levels, anti-tartrate acid phosphatase (TRACP-5b) levels and traditional Chinese medicine (TCM) syndrome scores. We assessed the regulatory roles of miRNAs in PMOP patients by analysing publicly available data from the Gene Expression Omnibus (GEO) database. Bioinformatics methods were also used to explore the mechanism by which YGD regulates miRNAs that are involved in bone metabolism. Results: Compared with those before treatment, the BMD, ALP levels, TRACP-5b levels, TCM syndrome scores and VAS scores improved in both groups after 3 months of treatment (P < 0.05). A total of 82 miRNAs differed between the groups. After analysing data from the GEO database, we confirmed that miR-133a-3p is the key molecule that mediates the effects of YGD intervention on PMOP. GO analysis of key genes suggested that gene enrichment was more pronounced in response to hormones, cellular response to growth factor stimulation, and positive regulation of physiological and metabolic processes. KEGG analysis revealed that these genes were enriched mainly in the PI3K-Akt, FOXO, and JAK-STAT pathways and other pathways. The results of the protein‒protein interaction (PPI) network analysis revealed that epidermal growth factor receptor (EGFR), Insulin-like growth factor 1 (IGF-1), Caveolin-1 (Cav-1) and others were core proteins. Conclusion: This study demonstrated that YGD is beneficial in the treatment of PMOP, ameliorating clinical symptoms and bone turnover indices. Moreover, the inhibition of miR-133a-3p expression may be the key mechanisms by which YGD regulates bone metabolism in the treatment of PMOP, although YGD regulates bone metabolism in a multitarget and multipathway manner.

- Abstract
Background: A new model of care enables French physiotherapists (PT) working in collaboration with family physicians (FP) to expand their usual scope of practice for patients with acute low back pain (LBP). The aim of our study is to evaluate the impact of this new first-contact physiotherapy (FCP) advanced practice model compared to usual FP care. Methods: A multicentre pragmatic non-inferiority cluster randomised controlled trial (RCT) has been conducted in six multidisciplinary primary healthcare centres in France. Patients from 20 to 55 years old with acute LBP consulted either the PT or the FP. PT independently assessed and managed patients including medication prescription. The primary outcome measure was disability at six weeks (Roland Morris Disability Questionnaire, range 0–24). Secondary outcomes include pain, risk disability prognosis, satisfaction with care, healthcare resources use and wait times. Data were collected at baseline, six and twelve weeks. Outcomes across arms were compared using mixed models regression analysis. Except for non-inferiority analysis of the primary outcome measure, other analyses were performed with a two-sided significance level of 0.05. Results: Sixty patients were recruited (PT: 32, FP: 28). The adjusted mean difference between groups for disability at 6 weeks was 0.39 in favour of the FP group (95%CI: -2.03; 2.81, p = 0.753). Considering a 5 points minimal clinically important difference, the FCP-led model of care was not inferior to usual FP care for the primary outcome. There was no statistically significant difference between groups in disability at 3 months and pain at 6 weeks and 3 months. PTs prescribed significantly less medications than FPs (p < 0.001). No statistically significant difference was found for other healthcare resource use outcomes, patients’ satisfaction and wait times. Conclusion: This is the first RCT to evaluate the impact of a FCP advanced practice model of care including medical delegated acts in a primary care setting. Our results suggest that the FCP-led model of care is not inferior to usual FP care regarding disability at 6 weeks. The FCP model could result in possible benefits in terms of healthcare resources use. Further adequate powered studies with larger sample size are needed to draw stronger conclusions. Trial registration: The study has been registered in ClinicalTrials.gov (NCT05200533) on the 20th of January 2022. [ABSTRACT FROM AUTHOR]

Background: Open liver surgery remains a primary surgical approach for complex liver resections and liver transplantation. However, the postoperative pain management is still a major challenge. Ultrasound-guided external oblique intercostal (EOI) plane block is a novel approach of regional anaesthesia and has a great potential to relieve postoperative pain after upper abdominal surgeries. This study aims to investigate the efficacy and safety of ultrasound-guided EOI plane block in managing postoperative pain after open liver surgery. Methods: Seventy-four participants scheduled for open liver surgery will be randomly assigned to either the intervention group, receiving an ultrasound-guided EOI plane block with a single dose of 30 ml 0.375% ropivacaine, or the control group, which will not receive this block. All participants will be provided with opioid-based patient-controlled intravenous analgesia (PCIA) postoperatively. The primary outcome is resting pain score at 3 h postoperatively, assessed using numerical rating scale. Secondary outcomes include pain score at 6, 24, 48, and 72 h postoperatively, perioperative opioid consumption, remedial analgesics within 72 h postoperatively, PCIA usage within postoperative 72 h, postoperative recovery, length of hospital stay, postoperative side effects, block-related complications, and ropivacaine plasma concentration of participants receiving the block. Discussion: This study is a randomised controlled trial to evaluate the efficacy and safety of ultrasound-guided EOI plane block for postoperative analgesia after open liver surgery. As regional anaesthesia plays an important role in the multimodal pain management, EOI plane block may prove to be an effective regional technique for enhancing postoperative pain relief and contributing to enhanced recovery after open liver surgery.

Objective: Eating disorders are complex illnesses with high morbidity and mortality. Yet, there is promising evidence to support the effects of nutrition on the brain and behaviour. One proposed example is the use of tyrosine as an adjunct treatment in anorexia nervosa (AN). However, recruitment and retention in eating disorder clinical trials has posed difficulties for researchers. The aim of this study was to pilot test a parallel randomised controlled trial (RCT) of tyrosine supplementation to explore the feasibility of recruitment and retention, intervention adherence and data collection methods from the perspective of participants and researchers. Method: Feasibility was assessed using numbers participating, questionnaire completion in patients and parent/carers completing and declining participation, a researcher implementation record and clinical measures. Subjects included adolescents aged 12–17 years with AN. The study was conducted over a 12-week period, with the intervention group receiving 5 mg of L-tyrosine supplement and the control group receiving a placebo. Results: Recruitment targets were not met and recruitment to a full RCT based on the current study protocol and recruitment sites did not prove feasible. Of the 39 approached for RCT participation, seven were recruited to the RCT (18% response rate) despite extending recruitment periods, with 100% retained and analysed. Patients or parents/carers identified barriers to study participation including burden, the need to consume tyrosine as tablets, and the use of blood, urine and psychological testing. Blood tyrosine rose markedly for subjects in the intervention group. No side effects were reported or measured. Conclusions: This study offers a unique exploration of the feasibility of a tyrosine trial in anorexia nervosa and is of relevance to assist the success of future nutrition trials. Exploring the suitability of future study designs for nutrition intervention research is warranted. Plain English Summary: Eating disorders are serious mental illnesses and exploration of effective treatments are required as a priority. This study explored whether using of a dietary protein (tyrosine) in supplement form added to usual treatment appeared feasible and acceptable to study participants. Study components perceived as potential barriers included use of tyrosine capsules as well as physical and psychological testing. Exploring suitable future study designs for nutrition intervention research with people with an eating disorder and parents/carers is required. [ABSTRACT FROM AUTHOR]

Introduction: Hypertensive intracerebral hemorrhage (HICH) is a condition associated with significant morbidity, mortality, and disability, particularly among the elderly population. The management of moderate thalamic-basal ganglia cerebral hemorrhage primarily relies on conservative approaches. Nevertheless, the rate of long-term disability remains high. In recent years, there has been significant advancement in minimally invasive surgery and diffusion tensor imaging techniques. Consequently, the utilization of Diffusion Tensor Imaging (DTI) technology in patients with cerebral haemorrhage allows for the identification of the haematoma's location in relation to the Corticospinal Tract (CST). This enables the development of precise puncture pathways that can be visualized, thereby avoiding any potential damage to the CST. Methods and analysis: Diffusion Tensor Imaging (DTI) is a method used to assess the structural and physiological characteristics of biological tissue by examining the diffusion behavior of water molecules.In the central nervous system, limb paralysis will be inevitable if the corticospinal tract is damaged. By employing DTI imaging techniques on individuals, it becomes possible to visualize the spatial relationship between the hematoma and the CST. This approach allows avoidance of the CST during preoperative planning of the puncture path, thus reducing secondary injuries caused by the procedure. The primary objective of this study was to assess the ability of patients in the minimally invasive surgery group and the conservative group to perform activities of daily living after 6 months of treatment. In addition, secondary outcomes included assessment of hematoma resorption/clearance ratios, cytokine levels, complication rates, and therapeutic indexes at different treatment durations, as well as long-term safety and efficacy at 2–3 years of follow-up. Furthermore, subgroup analysis, and sensitivity analysis were conducted to further analyze the data. Logistic single-variate and multivariate regression analyses were applied to understand the adverse factors affecting prognosis. Ethics and dissemination: The clinical study was reviewed and approved by the Ethics Committee of the First People's Hospital of Yibin. The ethical number is: 2023 Review (64). Registration number: This protocol is registered in the Prospective Registry of Chinese Clinical Trial Registries (PROCCTR). The full date of first registration is 28/12/2023.

Background: The increasing prevalence of mental health disorders in the United Kingdom necessitates the exploration of novel treatment modalities. This study aimed to assess the feasibility and acceptability of conducting a randomised controlled trial (RCT) evaluating the efficacy of four osteopathic interventions on psychophysiological and mental health outcomes. Methods: A mixed-methods feasibility study with an explanatory sequential design was implemented. The quantitative phase involved randomising 42 participants into four intervention groups: (1) high-velocity and articulation techniques (HVAT), (2) soft-tissue massage (STM), (3) craniosacral therapy (CST), and (4) a combination approach. Primary outcome measures encompassed recruitment rate, assessment duration, questionnaire completion, intervention attrition, and adverse events. Secondary outcomes included validated assessments of depression, anxiety, stress, psychological flexibility, heart rate variability (HRV), and interoception, administered pre- and post-intervention. Analysis of variance (ANOVA) was employed to evaluate pre-post intervention changes. The qualitative phase comprised semi-structured interviews analysed using thematic analysis. Results: The study achieved a recruitment rate of 21 eligible participants per month, with 54.8% of respondents meeting eligibility criteria. All 33 participants who completed the study underwent interventions and assessments within the allocated one-hour timeframe, with full questionnaire completion. The attrition rate was 21%. No adverse events were reported. Qualitative analysis revealed positive participant experiences, with themes highlighting good practitioner communication, intervention accessibility, and increased bodily awareness. Some participants found the questionnaire battery burdensome. Exploratory quantitative analyses showed variations in effects across interventions for heart rate variability, interoceptive accuracy, and mental health measures, but these results should be interpreted cautiously due to the small sample size. Conclusions: This study provides evidence supporting the feasibility and acceptability of a larger-scale RCT investigating osteopathic interventions for individuals presenting with mild psychological symptoms. The preliminary findings suggest potential efficacy in improving mental health outcomes, warranting further investigation. Trial registration NCT05674071, registered 06/01/2023.

The primary aim of this study was to establish the feasibility of implementing a larger RCT designed to evaluate the effect of financial incentives on HCV treatment initiation among persons receiving opioid agonist therapy and/or who have injected drugs in the prior six months. ETHOS Engage is an observational cohort of participants recruited from drug treatment and needle and syringe programs in Australia. Among 11 drug and alcohol clinics, participants who were HCV RNA-positive were randomized (1:1) to receive standard of care or a AUD $60 gift card at treatment initiation. Regarding feasibility, 100% (57/57) of eligible participants enrolled to take part. Twenty-eight participants were randomised to the financial incentive arm (AUD $60 gift card) plus standard of care and 29 participants to the standard of care arm. In this pilot RCT (n = 57), median age was 42 years (IQR 37–49), 63% were male (n = 36), 35% Indigenous (n = 20) and 36% (n = 21) reported injecting drugs daily in the past month. Twelve weeks post-study enrolment, 11 (39%) participants in the financial incentive arm and 17 (59%) participants in the standard of care arm initiated HCV treatment. Findings indicate high feasibility among people who inject drugs to be randomised to receive financial incentives to initiate HCV treatment. [ABSTRACT FROM AUTHOR]

Abstract Background Kidney transplantation is the ultimate treatment for end-stage kidney disease. Function of the kidney graft is not only dependent on medical factors but also on a complication-free surgical procedure. In the event of major surgical complications, the kidney graft is potentially lost and the patient will return to the waiting list which may be long. To optimise peri-operative care and reduce complications, robot-assisted kidney transplantation (RAKT) has been introduced as an alternative to open kidney transplantation (OKT), but to our knowledge, no randomised clinical trials (RCT) have compared RAKT to OKT. In this study, we will explore whether robot-assisted surgery can reduce 30-day surgical complications compared to open surgery in kidney transplantation. Methods This is a single-site, open-label, randomised clinical trial comparing RAKT to OKT. Participants are adult recipients of kidney transplantation recruited from Copenhagen University Hospital – Rigshospitalet, Denmark. The study plans to include 106 participants who will be randomised in a 1:1 manner between OKT and RAKT. Primary outcomes are vascular- and major surgical complications at 30 days post-operatively. Participants will be followed for 2 years to evaluate secondary outcomes including recovery, late complications and kidney graft function. This is designed as a superiority trial and planned analyses will follow intention-to-treat principles. Discussion Studies indicate RAKT can reduce several surgical complications, but the lack of RCTs limits the extrapolation of these results to justify replacing an open approach with a robot-assisted one. Ultimately, the introduction of new surgical techniques should be as vigorously tested as any other new treatments. However, reducing surgical complications that compromise graft viability could lead to improved patient care and survival. Trial registration The trial was prospectively registered with ClinicalTrials.gov on February 15th, 2023, with the identifier NCT05730257.

Abstract Background Cognitive impairment is common in haemodialysis patients with no known beneficial interventions. Cooler dialysate slows brain white-matter changes, but its effect on cognition is unknown. This feasibility trial was performed to inform a fully-powered, randomised trial to assess this. Methods We aimed to randomise (1:1) 90 haemodialysis patients to this double-blinded, randomised controlled feasibility trial to standard care (dialysate-temperature 36.5 °C) or intervention (35 °C). Eligible patients were adult chronic haemodialysis recipients with no established diagnosis of dementia or psychiatric disease. The primary outcome was change in Montreal Cognitive Assessment (MoCA) score at 12-months. Secondary outcomes included recruitment and attrition rates, reasons for non-recruitment, intradialytic hypotension, depression, patient burden, computerised cognition test battery, and quality of life. Findings Of 334 patients screened, 160 were eligible. 99 declined mainly for the extra non-dialysis day study visits. Sixty-one patients consented, 43 randomised – 20 in standard care, 23 in intervention arms; 13 withdrew for non-dialysis day visits and 5 without reason before randomisation. 27 patients (12 standard care, 15 intervention) completed the trial – 5 died, 1 transplanted, 4 withdrew consent, and 6 could not attend due to the pandemic. Low temperature dialysis was well tolerated. There was no difference in change in MoCA from baseline to 12 months between the standard and intervention arms; 1.0 (-2.8–3.0, p = 0.755) and − 2.0 (-1.0 - -4.0, p = 0.047) respectively. There were no differences between groups on any secondary measures. There were no significant adverse events reported. Discussion The trial was significantly affected by the COVID-19 pandemic contributing to an attrition rate of 27%. The non-dialysis day research visits were mainly responsible for low recruitment and consent withdrawal. There are several learning points, described in the article, which will inform design of definitive trials in this area in the future. Trial registration ClinicalTrials.gov Identifier NCT03645733.

Spinal cord injury (SCI) is a severe lesion comporting various motor, sensory and sphincter dysfunctions, abnormal muscle tone and pathological reflex, resulting in a severe and permanent lifetime disability. The primary injury is the immediate effect of trauma and includes compression, contusion, and shear injury to the spinal cord. A secondary and progressive injury usually follows, beginning within minutes and evolving over several hours after the first ones. Because ischemia is one of the most important mechanisms involved in secondary injury, a treatment to increase the oxygen tension of the injured site, such as hyperbaric oxygen therapy, should theoretically help recovery. Although a meta-analysis concluded that hyperbaric oxygen therapy might be helpful for clinical treatment as a safe, promising and effective choice to limit secondary injury when appropriately started, useful and well-defined protocols/guidelines still need to be created, and its application is influenced by local/national practice. The topic is not a secondary issue because a well-designed randomized controlled trial requires a proper sample size to demonstrate the clinical efficacy of a treatment, and the absence of a common practice guideline represents a limit for results generalization. This narrative review aims to reassemble the evidence on hyperbaric oxygen therapy to treat SCI, focusing on adopted protocols in the studies and underlining the critical issues. Furthermore, we tried to elaborate on a protocol with a flowchart for an evidence-based hyperbaric oxygen therapy treatment. In conclusion, a rationale and shared protocol to standardize as much as possible is needed for the population to be studied, the treatment to be adopted, and the outcomes to be evaluated. Further studies, above all, well-designed randomized controlled trials, are needed to clarify the role of hyperbaric oxygen therapy as a strategic tool to prevent/reduce secondary injury in SCI and evaluate its effectiveness based on an evidence-based treatment protocol. We hope that adopting the proposed protocol can reduce the risk of bias and drive future studies.

Abstract Introduction Hypertensive intracerebral hemorrhage (HICH) is a condition associated with significant morbidity, mortality, and disability, particularly among the elderly population. The management of moderate thalamic-basal ganglia cerebral hemorrhage primarily relies on conservative approaches. Nevertheless, the rate of long-term disability remains high. In recent years, there has been significant advancement in minimally invasive surgery and diffusion tensor imaging techniques. Consequently, the utilization of Diffusion Tensor Imaging (DTI) technology in patients with cerebral haemorrhage allows for the identification of the haematoma’s location in relation to the Corticospinal Tract (CST). This enables the development of precise puncture pathways that can be visualized, thereby avoiding any potential damage to the CST. Methods and analysis Diffusion Tensor Imaging (DTI) is a method used to assess the structural and physiological characteristics of biological tissue by examining the diffusion behavior of water molecules.In the central nervous system, limb paralysis will be inevitable if the corticospinal tract is damaged. By employing DTI imaging techniques on individuals, it becomes possible to visualize the spatial relationship between the hematoma and the CST. This approach allows avoidance of the CST during preoperative planning of the puncture path, thus reducing secondary injuries caused by the procedure. The primary objective of this study was to assess the ability of patients in the minimally invasive surgery group and the conservative group to perform activities of daily living after 6 months of treatment. In addition, secondary outcomes included assessment of hematoma resorption/clearance ratios, cytokine levels, complication rates, and therapeutic indexes at different treatment durations, as well as long-term safety and efficacy at 2–3 years of follow-up. Furthermore, subgroup analysis, and sensitivity analysis were conducted to further analyze the data. Logistic single-variate and multivariate regression analyses were applied to understand the adverse factors affecting prognosis. Ethics and dissemination The clinical study was reviewed and approved by the Ethics Committee of the First People’s Hospital of Yibin. The ethical number is: 2023 Review (64). Registration number This protocol is registered in the Prospective Registry of Chinese Clinical Trial Registries (PROCCTR). The full date of first registration is 28/12/2023.

Abstract Background The increasing prevalence of mental health disorders in the United Kingdom necessitates the exploration of novel treatment modalities. This study aimed to assess the feasibility and acceptability of conducting a randomised controlled trial (RCT) evaluating the efficacy of four osteopathic interventions on psychophysiological and mental health outcomes. Methods A mixed-methods feasibility study with an explanatory sequential design was implemented. The quantitative phase involved randomising 42 participants into four intervention groups: (1) high-velocity and articulation techniques (HVAT), (2) soft-tissue massage (STM), (3) craniosacral therapy (CST), and (4) a combination approach. Primary outcome measures encompassed recruitment rate, assessment duration, questionnaire completion, intervention attrition, and adverse events. Secondary outcomes included validated assessments of depression, anxiety, stress, psychological flexibility, heart rate variability (HRV), and interoception, administered pre- and post-intervention. Analysis of variance (ANOVA) was employed to evaluate pre-post intervention changes. The qualitative phase comprised semi-structured interviews analysed using thematic analysis. Results The study achieved a recruitment rate of 21 eligible participants per month, with 54.8% of respondents meeting eligibility criteria. All 33 participants who completed the study underwent interventions and assessments within the allocated one-hour timeframe, with full questionnaire completion. The attrition rate was 21%. No adverse events were reported. Qualitative analysis revealed positive participant experiences, with themes highlighting good practitioner communication, intervention accessibility, and increased bodily awareness. Some participants found the questionnaire battery burdensome. Exploratory quantitative analyses showed variations in effects across interventions for heart rate variability, interoceptive accuracy, and mental health measures, but these results should be interpreted cautiously due to the small sample size. Conclusions This study provides evidence supporting the feasibility and acceptability of a larger-scale RCT investigating osteopathic interventions for individuals presenting with mild psychological symptoms. The preliminary findings suggest potential efficacy in improving mental health outcomes, warranting further investigation. Trial registration NCT05674071, registered 06/01/2023.

INTRODUCTION: The high incidences of both the developmental delay among young children and the mental health problems of their caregivers are major threats to public health in low-income and middle-income countries. Parental training interventions during early childhood have been shown to benefit early development, yet evidence on strategies to promote caregiver mental health remains limited. In addition, evidence on the optimal design of scalable interventions that integrate early child development and maternal mental health components is scarce. METHODS AND ANALYSIS: We design a single-blind, factorial, cluster-randomised controlled, superiority trial that will be delivered and supervised by local agents of the All China Womens Federation (ACWF), the nationwide, government-sponsored social protection organisation that aims to safeguard the rights and interests of women and children. We randomise 125 villages in rural China into four arms: (1) a parenting stimulation arm; (2) a caregiver mental health arm; (3) a combined parenting stimulation and caregiver mental health arm and (4) a pure control arm. Caregivers and their children (aged 6-24 months at the time of baseline data collection) are selected and invited to participate in the 12-month-long study. The parenting stimulation intervention consists of weekly, one-on-one training sessions that follow a loose adaptation of the Reach Up and Learn curriculum. The caregiver mental health intervention is comprised of fortnightly group activities based on an adaptation of the Thinking Healthy curriculum from the WHO. Primary outcomes include measures of child development and caregiver mental health. Secondary outcomes include a comprehensive set of physical, psychological and behavioural outcomes. This protocol describes the design and evaluation plan for this programme. ETHICS AND DISSEMINATION: This study received approval from the Institutional Review Board of Stanford University (IRB Protocol #63680) and the Institutional Review Board of the Southwestern University of Finance and Economics in Chengdu, Sichuan, China. Informed oral consent will be obtained from all caregivers for their own and their childs participation in the study. The full protocol will be publicly available in an open-access format. The study findings will be published in economics, medical and public health journals, as well as Chinese or English policy briefs.

Abstract Background This paper reports the results from a feasibility trial of an early parent-delivered social communication intervention for young children with Down syndrome (‘ASCEND’). The intervention focuses on developing children’s early social communication skills, in particular responding to shared attention. The aim was to inform the feasibility of running a full-scale trial through National Health Service (NHS) Speech and Language Therapy (SaLT) services, to assess whether the intervention is effective in improving language skills before children with Down syndrome start school. Methods This was a two-arm feasibility randomised controlled trial (RCT), with 1:1 randomisation stratified by trial site, comparing the intervention plus standard NHS SaLT provision with standard NHS SaLT alone. We recruited 20 children with Down syndrome aged between 11 and 36 months through 3 NHS SaLT services, 19 of whom were randomised (10 — intervention group, 9 —control group). Pre- and post-intervention and 6-month follow-up assessments included language, social communication skills, adaptive behaviour, quality of life (parents and children), parental anxiety and depression. The intervention was parent delivered with parents having access to SaLT services and the research team during the intervention. Data were collected on recruitment and retention, standard care, treatment fidelity, acceptability of the intervention by the parents and speech and language therapists, feasibility of collecting health economic measures and suitability of the primary outcome measure. Results The sample was sufficient for a feasibility study. The intervention (manual, support, materials) was positively received by the participating parents. Speech and language therapists also evaluated the acceptability of the intervention positively. Treatment fidelity which was measured by completion of weekly parent diaries and two adherence phone call was acceptable as 100% of the parent diaries were returned, over 90% of the parental diaries were completed correctly and 100% of adherence phone calls were completed. Retention was acceptable at 84% overall. The preliminary health economic data suggest that this intervention will be low cost. The sample size calculation suggests that 290 participants would need to be recruited, with 228 having a complete data set, for a full RCT. Conclusion Based on recruitment, retention and treatment fidelity, as well as the acceptability of the intervention to parents and speech and language therapists, a full-scale trial would be feasible in order to assess the effectiveness of the intervention.

Abstract Background Tackling poor mental health in university students has been identified as a priority in higher education. However, there are few evidence-based prevention initiatives designed for students. Repetitive Negative Thought (RNT, e.g. worry, rumination) is elevated in university students and is a well-established vulnerability factor for anxiety and depression. Furthermore, there are now evidence-based cognitive-behavioural interventions to tackle RNT. A mobile self-help cognitive-behavioural app targeting RNT, adapted for students may therefore be an effective, scalable, and acceptable way to improve prevention in students. Methods An online single blind, two-arm parallel-group Randomised Controlled Trial (RCT) to examine the incidence of major depression and symptoms of anxiety and depression across 12 months in university students aged over 16 who screen into the study with self-reported high levels of worry and/or rumination and no current diagnosis of major depression. Eligible participants will be randomised to the active intervention arm (usual practice plus using a self-guided mobile app targeting RNT) or to the control arm (usual practice). In total, 648 participants aged over 16, with no current major depression, bipolar disorder or psychosis will be recruited from UK universities. Assessments will take place at baseline (pre-randomisation), 3 months and 12 months post- randomisation. Primary endpoint and outcome is incidence of major depression as determined by self-reported diagnostic criteria at 12-month follow-up. Depressive symptoms, anxiety, well-being, health-related quality of life, functioning and academic outcomes are secondary outcomes. Compliance, adverse events, and potentially mediating variables will be carefully monitored. Discussion The trial aims to provide a better understanding of the causal role of tackling RNT (worry, rumination) using a self-help mobile app with respect to preventing depression in university students. This knowledge will be used to develop and disseminate innovative evidence-based, feasible, and effective mobile-health public health strategies for preventing common mental health problems.

Abstract Healthcare organisations worldwide are affected by the shortage of health professionals due to work-related stress and health professional leaders play an important role by implementing effective strategies. Therefore, this study aims to investigate whether the STRAIN intervention program (using evidence-based training for health professional leaders) can reduce work-related stress among health professionals. This study is based on a cluster randomised controlled trial, consists of three measurements and includes 165 participating hospitals, nursing homes and home care organisations. A total of 206 health professional leaders took part in the intervention programme and 19,340 health professionals participated in the study. Results showed no significant differences (p > 0.05) between the intervention and control group regarding the effort-reward imbalance ratio, quantitative demands, opportunities for development, bond with the organisation, quality of leadership, social community, role clarity, rewards, difficulties with demarcation and work–private life conflict. Pre-/post-test analysis revealed a tendency for significant positive results (p

Abstract Background Suicide has become a first-order public health concern, especially following the negative impact of COVID-19 on the mental health of the general population. Few studies have analysed the effects of early psychotherapeutic interventions on subjects who have attempted suicide, and even fewer have focused on those hospitalized in non-psychiatric units after a Medically Serious Suicide Attempt (MSSA). The main aim of this study is to describe the protocol designed to evaluate the effectiveness of individual psychological treatment for patients hospitalized after an MSSA. The secondary objectives of the study are: (1) to evaluate the impact on quality of life and other psychosocial variables of patients with a recent MSSA who receive early psychological intervention; (2) to analyse the biological, psychological, and clinical impact of early psychotherapeutic treatment on subjects hospitalized after an MSSA. Methods A longitudinal randomised controlled trial will be conducted with patients over 16 years of age admitted to two general hospitals. The case intervention group will enrol for 8-sessions of individual psychotherapy, Suicide Attempts Multi-component Intervention Treatment (SAMIT), combining Dialectical Behaviour Therapy (DBT), Mentalization-Based Therapy (MBT), and Narrative approaches, while the control group will receive a treatment-as-usual intervention (TAU). Longitudinal assessment will be conducted at baseline (before treatment), post-treatment, and 3, 6, and 12 months after. The main outcome variable will be re-attempting suicide during follow-up. Discussion Some psychotherapeutic interventions, usually implemented in outpatient, have proven to be effective in preventing suicidal behaviours. The combination of some of these may be a powerful treatment for preventing future SA in patients hospitalised after an MSSA, which is the most severely suicidal subgroup. Moreover, assessment of the biological, clinical and psychometric impact of this new intervention on patients during the first year after the attempt may help understand some of the multi-level factors associated with the effectiveness of psychotherapeutic interventions in MSSAs. The prevalence of high suicide rates requires the design of effective psychological interventions for their prevention, and also in order to design new pharmacological and psychological treatments.

Abstract Background Loneliness is common among older adults in institutional settings. It leads to adverse effects on health and wellbeing, for which nature contact with peers in turn may have positive impact. However, the effects of nature engagement among older adults have not been studied in randomised controlled trials (RCT). The “Friends in Nature” (FIN) group intervention RCT for lonely older adults in Helsinki assisted living facilities (ALFs) aims to explore the effects of peer-related nature experiences on loneliness and health-related quality of life (HRQoL). In this study we aim describe the participants’ baseline characteristics of the RCT, feasibility of FIN intervention and intervention participants’ feedback on the FIN. Methods Lonely participants were recruited from 22 ALFs in Helsinki area, Finland, and randomised into two groups: 1) nature-based social intervention once a week for nine weeks (n = 162) and 2) usual care (n = 157). Demographics, diagnoses and medication use were retrieved from medical records, and baseline cognition, functioning, HRQoL, loneliness and psychological wellbeing were assessed. Primary trial outcomes will be participants’ loneliness (De Jong Giervald Loneliness Scale) and HRQoL (15D). Results The mean age of participants was 83 years, 73% were female and mean Minimental State Examination of 21 points. The participants were living with multiple co-morbidities and/or disabilities. The intervention and control groups were comparable at baseline. The adherence with intervention was moderate, with a mean attendance of 6.8 out of the nine sessions. Of the participants, 14% refused, fell ill or were deceased, and therefore, participated three sessions or less. General subjective alleviation of loneliness was achieved in 57% of the intervention participants. Of the respondents, 96% would have recommended a respective group intervention to other older adults. Intervention participants appreciated their nature excursions and experiences. Conclusions We have successfully randomised 319 lonely residents in assisted living facilities into a trial about the effects of nature experiences in a group-format. The feedback from participants was favourable. The trial will provide important information about possibilities of alleviating loneliness with peer-related nature-based experiences in frail residents.

Abstract Background Computerised cognitive training (CCT) can improve the cognitive abilities of people with mild cognitive impairment (MCI), especially when the CCT contains a learning system, which is a type of machine learning (ML) that automatically selects exercises at a difficulty that corresponds to the person’s peak performance and thus enables individualised training. Methods We developed one individualised CCT (iCCT) with ML and one basic CCT (bCCT) for an active control group (CG). The study aimed to determine whether iCCT in the intervention group (IG) resulted in significantly greater enhancements in overall cognitive functioning for individuals with MCI (age 60+) compared with bCCT in the CG across a 6-month period. This double-blind randomised controlled study was conducted entirely virtually. The 89 participants were community-dwelling people with a psychometric diagnosis of MCI living in Germany. The iCCT stimulates various cognitive functions, especially working memory, visuo-constructional reasoning, and decision-making. The bCCT includes fewer and simpler tasks. Both CCTs were used at home. At baseline and after 6 months, we assessed cognitive functioning with the Montreal Cognitive Assessment (MoCA). A mixed-model ANCOVA was conducted as the main analysis. Results Both CCTs led to significant increases in average global cognition. The estimated marginal means of the MoCA score increased significantly in the CG by an average of 0.9 points (95% CI [0.2, 1.7]) from 22.3 (SE = 0.25) to 23.2 (SE = 0.41) points (p = 0.018); in the IG, the MoCA score increased by an average of 2.2 points (95% CI [1.4, 2.9]) from 21.9 (SE = 0.26) to 24.1 (SE = 0.42) points (p

Abstract Background Randomised controlled trials (RCTs) are considered the gold standard for generating clinical evidence. The focus on high internal validity in RCTs challenges the external validity and generalisability of findings, potentially hindering their application in routine care. In neurorehabilitation, limited literature addresses conducting RCTs feasibly and efficiently. We investigated barriers and facilitators to conducting RCTs within routine care of neurorehabilitation centres from the perspective of stakeholders in neurorehabilitation in Germany and Austria. Methods We conducted semi-structured interviews with stakeholders in neurorehabilitation from four centres in Germany and Austria, informed by the Theoretical Domains Framework (TDF) and the Capability, Opportunity, Motivation and Behaviour model (COM-B). Employing a hybrid approach, the interview analysis integrated both deductive, theory-driven analysis based on the TDF domains and COM-B model and inductive, reflexive thematic analysis. Results Twelve stakeholders (4 physicians, 4 therapy managers, 4 therapists; 5 females, 7 males; with research experience spanning 0–40 years) were interviewed. Key barriers to conducting RCTs in neurological rehabilitation centres include limited financial, human, and time resources, high clinical workloads, and a lack of interest of some therapists. Ineffective leadership, perceived lack of research expertise, and communication issues were also significant barriers. Social influence factors such as lack of employer support and inadequate training access further contributed to the challenges. Additionally, barriers included insufficient research infrastructure, limited space, internal power struggles, and rigid cost bearer specifications. Key facilitators included physicians’ and therapists’ motivation to advance the field, contribute to knowledge, and to prioritise patient health. Support from supervisors, joint decision-making, and efficient organisation were crucial facilitators. Flexible therapy planning, mutual support, and interdisciplinary collaboration also played important roles. Conclusion Our results suggest that increasing professional development and understanding, along with providing adequate financial, human, time, and spatial resources to support research endeavours, implementing effective communication strategies to enhance interdisciplinary collaboration and coordination among team members may contribute to increased motivation and facilitate RCTs within the setting of neurorehabilitation centres. Trial registration This study was prospectively registered with the German Clinical Trials Register (08.04.2021 DRKSID DRKS00024982).

Abstract Background Chronic diseases are a significant and growing problem of our time. They impair the ability to work and increase the risk of early retirement. To support the return to work, rehabilitation services can be applied for in Germany. Currently, the application system for rehabilitation allows only a limited degree of individualisation of the treatment and is associated with a lack of multidisciplinary communication. To facilitate rehabilitation care planning, we developed a complex intervention. A digital, platform-based case management approach (intervention) will ensure multidisciplinary communication and the tailored selection of medical treatments and/or non-medical support measures. The overall objective is to assess the effectiveness of the intervention compared to treatment as usual (control condition). The German Federal Ministry of Labour and Social Affairs (BMAS) funds the RehaPro-SERVE study (grant number: 661R0053K1). Methods This is the protocol for an investigator-initiated, pragmatic, multicentre, randomised and controlled two-arm parallel-group superiority trial with embedded qualitative process evaluation. The study will be conducted in Hesse state, Germany. N = 59 primary care physicians will be recruited and tasked with the recruitment of six eligible patients each. Eligibility criteria: age 40–60; minimum of 4-week work disability due to musculoskeletal, oncologic or psychological conditions or the post-COVID-19 syndrome within the last 6 months; at high risk for early retirement. In total, n = 352 patients will be randomised with a 1:1 allocation to intervention or control group and stratified by primary care practice using permuted blocks. The primary outcome is the number of days of sick leave during a 12-month period after the assumed completion of treatments (t1 to t2). Secondary outcomes include the number of days of sick leave (self-report), work ability, and health-related quality of life, as well as data from the qualitative process evaluation. Discussion The results of the study will inform the design of future care services and provide valuable information on multidisciplinary case management in the context of rehabilitation care planning. The results of the qualitative process evaluation will further contribute to the understanding of facilitating and hindering factors.

Abstract Background The World Health Organization’s (WHO) Mental Health Gap Action Programme (mhGAP) is a validated intervention that can be provided by non-specialised healthcare workers to individuals with unhealthy alcohol use. However, it typically requires several in-person sessions at a health facility, which may limit its feasibility and effectiveness in remote settings. This trial compares mhGAP-Standard, a 4 to 6 in-person session intervention, to mhGAP-Remote, a 1 in-person session intervention followed by 8 week of short message service (SMS) in Lesotho. We hypothesise that mhGAP-Remote is superior to mhGAP-Standard in reducing alcohol use (as detailed by the primary and secondary outcomes below). Methods This is a two-arm randomised open-label multicentre superiority trial. Participants allocated to mhGAP-Standard receive 4 in-person sessions using motivational interviewing, identifying triggers, and alternative behaviours, with the option of two additional booster sessions. Participants in the mhGAP-Remote arm receive 1 in-person session covering the same content, followed by standardised SMSs over 8 weeks that reinforce intervention content. Non-specialist providers deliver the intervention and receive weekly supervision. Adults (N planned = 248) attending participating health facilities for any reason and who meet criteria for unhealthy alcohol use based on the Alcohol Use Disorders Identification Test ([AUDIT] score ≥ 6 for women, ≥ 8 for men) are individually randomised to the two arms (1:1 allocation, stratified by participant sex and age (≥ 50 vs

Abstract Background The aim of this study is to evaluate the efficacy and safety of faecal microbiota transplantation (FMT) for the treatment of irritable bowel syndrome (IBS). Methods We searched four databases for randomised controlled trials (RCTs) that compared FMT with a control intervention in patients with IBS. The revised Cochrane risk-of-bias (RoB) tool was chosen for appraisal. Meta-analysis with trial sequential analysis (TSA) was conducted. Grading of Recommendations Assessment Development and Evaluation (GRADE) methodology was used to assess the certainty of evidence (CoE). Results We included 12 RCTs with a total of 615 participants. Meta-analyses showed no significant difference between the FMT and control groups in terms of clinical responses (relative risk [RR] = 1.44, 95% confidence interval [CI] 0.88–2.33) and changes in IBS Severity Scoring System (IBS-SSS) scores (standardised mean difference [SMD] = − 0.31, 95% CI − 0.72 to 0.09) and IBS Quality of Life (IBS-QOL) scores (SMD = 0.30, 95% CI − 0.09 to 0.69). Subgroup analysis revealed that in studies with low RoB and using endoscopy, nasojejunal tube and rectal enema delivery, FMT led to a significant improvement in clinical responses and changes in IBS-SSS and IBS-QOL scores. TSA suggested that the current evidence is inconclusive and that the CoE is very low. Conclusion This study suggests that patients with IBS may benefit from FMT especially when it is administered via endoscopy, nasojejunal tube or rectal enema. However, the certainty of evidence is very low. Further research is needed to confirm the efficacy and safety of FMT for IBS treatment.

Abstract Background Experimental studies of wound healing often use survival analysis and time to event outcomes or differences in wound area at a specific time point. However, these methods do not use a potentially large number of observations made over the course of a trial and may be inefficient. A model-based approach can leverage all trial data, but there is little guidance on appropriate models and functional forms to describe wound healing. Methods We derive a general statistical model and review a wide range of plausible mathematical models to describe wound healing. We identify a range of possible derived estimands and their derivation from the models. Using data from a trial of an intervention to promote ulcer healing in patients affected by leprosy that included three measurement methods repeated across the course of the study, we compare the goodness-of-fit of the models using a range of methods and estimate treatment effects and healing rate functions with the best-fitting models. Results Overall, we included 5,581 ulcer measurements of 1,578 unique images from 130 patients. We examined the performance of a range of models. The square root, log square root, and log quadratic models were the best fitting models across all outcome measurement methods. The estimated treatment effects magnitude and sign varied by time post-randomisation, model type, and outcome type, but across all models there was little evidence of effectiveness. The estimated effects were significantly more precise than non-parametric alternatives. For example, estimated differences from the three outcome measurements at 42-days post-randomisation were − 0.01 cm2 (-0.77, 0.74), -0.44 cm2 (-1.64, 0.76), and 0.11 cm2 (-0.87, 1.08) using a non-parametric method versus − 0.03 cm2 (-0.14, 0.06), 0.06 cm2 (-0.05, 0.17), and 0.03 cm2 (-0.07, 0.17) using a square-root model. Conclusions Model-based analyses can dramatically improve the precision of estimates but care must be taken to carefully compare and select the best fitting models. The (log) square-root model is strongly recommended reflecting advice from a century ago.

Abstract Background Reusable surgical drapes have a lower lifetime environmental impact than disposable drapes in most cases. There is limited evidence regarding whether drape choice impacts patient outcomes including post-operative wound complications. The aim of this study is to compare wound complication rates following routine neutering surgeries in cats and dogs when reusable drapes are used as compared with disposable drapes. Methods The trial will be conducted as a pragmatic, multi-centre, parallel group randomised controlled trial in the UK. Dogs and cats undergoing routine neutering will be randomised to disposable or reusable drapes with all other aspects of care occurring as they usually would at the practice. The required sample size is 2,850, with 4750 animals to be recruited from up to ten practices to allow for a 40% loss to follow-up. Demographic data and details on peri-operative care will be collected at the time of surgery. Post-operative wound complications will be assessed and recorded as usual at each practice using clinical codes. The post-operative wound clinical codes and any antibiotic use within 30 days of surgery will be retrieved from the practice management software. The primary outcome that will be compared between the two groups is the rate of post-operative wound complications within 30 days of surgery which will be analysed by multivariable logistic regression with a binary outcome of wound complication (yes/no). Secondary outcomes are the prevalence of different types of complications and antibiotic use within 30 days of surgery which will be compared between the two groups by chi square analysis. Discussion Our hypothesis is that there will be no difference in post-operative wound complication rates between disposable and reusable drapes. If the likely rate of post-surgical wound complications with reusable drapes is similar to that with disposable drapes, then veterinary clinical teams can choose the more sustainable option, confident that their patients will not be impacted by this choice. Trial registration We have retrospectively registered the protocol on the Open Science Framework on 14 Nov 2023 (Trial registration entry: https://doi.org/10.17605/OSF.IO/72HMA ).

Abstract Background An adaptive design allows modifying the design based on accumulated data while maintaining trial validity and integrity. The final sample size may be unknown when designing an adaptive trial. It is therefore important to consider what sample size is used in the planning of the study and how that is communicated to add transparency to the understanding of the trial design and facilitate robust planning. In this paper, we reviewed trial protocols and grant applications on the sample size reporting for randomised adaptive trials. Method We searched protocols of randomised trials with comparative objectives on ClinicalTrials.gov (01/01/2010 to 31/12/2022). Contemporary eligible grant applications accessed from UK publicly funded researchers were also included. Suitable records of adaptive designs were reviewed, and key information was extracted and descriptively analysed. Results We identified 439 records, and 265 trials were eligible. Of these, 164 (61.9%) and 101 (38.1%) were sponsored by industry and public sectors, respectively, with 169 (63.8%) of all trials using a group sequential design although trial adaptations used were diverse. The maximum and minimum sample sizes were the most reported or directly inferred (n = 199, 75.1%). The sample size assuming no adaptation would be triggered was usually set as the estimated target sample size in the protocol. However, of the 152 completed trials, 15 (9.9%) and 33 (21.7%) had their sample size increased or reduced triggered by trial adaptations, respectively. The sample size calculation process was generally well reported in most cases (n = 216, 81.5%); however, the justification for the sample size calculation parameters was missing in 116 (43.8%) trials. Less than half gave sufficient information on the study design operating characteristics (n = 119, 44.9%). Conclusion Although the reporting of sample sizes varied, the maximum and minimum sample sizes were usually reported. Most of the trials were planned for estimated enrolment assuming no adaptation would be triggered. This is despite the fact a third of reported trials changed their sample size. The sample size calculation was generally well reported, but the justification of sample size calculation parameters and the reporting of the statistical behaviour of the adaptive design could still be improved.

Abstract Background Azithromycin has been shown to be beneficial in preventing infectious diseases, including malaria, infectious diarrhoea and pneumonia. A cluster randomised control trial on azithromycin MDA in children in Niger, Malawi and Tanzania found a reduction in all-cause under-five (U5) mortality in communities who received azithromycin compared to placebo. However, the reduction was largest and statistically significant only in Niger. The purpose of this trial is to evaluate the impact of azithromycin plus intermittent preventive treatment in infants (IPTi), recently renamed by the World Health Organisation as perennial malaria chemoprevention (PMC), with sulfadoxine-pyrimethamine (SP) on all-cause mortality up to 18 months of age in children living in areas of high mortality burden through the Expanded Program on Immunisation (EPI) in Sierra Leone. Methods The Improving Care through Azithromycin Research for Infants in Africa (ICARIA) trial is a phase III two-arm, individually randomised, double-blinded, placebo-controlled trial administering oral AZI (20 mg/kg bodyweight) at three time points to children attending EPI visits in Sierra Leone. A total of 20,560 infants attending the first EPI contact at around 6 weeks of age are recruited and randomised to AZI or placebo in a 1:1 ratio. The second and third AZI/placebo doses are given at 9 and 15 months of age. The primary outcome of the trial is all-cause mortality rate at 18 months of age assessed through mortality surveillance. Other trial outcomes include the impact on antimicrobial resistance, and on the immune response to certain key routine EPI immunisations, the safety of the intervention, the prevalence of SP resistance markers and the feasibility, and acceptability of adding AZI to the EPI programme. Discussion The trial will provide the evidence needed to inform policy regarding the adoption and large-scale implementation of AZI in areas of high-mortality burden in sub-Saharan Africa.

Abstract Background The number of surgical trials is increasing but such trials can be complex to deliver and pose specific challenges. A multi-centre, Phase III, RCT comparing Posterior Cervical Foraminotomy versus Anterior Cervical Discectomy and Fusion in the Treatment of Cervical Brachialgia (FORVAD Trial) was unable to recruit to target. A rapid qualitative study was conducted during trial closedown to understand the experiences of healthcare professionals who participated in the FORVAD Trial, with the aim of informing future research in this area. Methods Semi-structured interviews were conducted with 18 healthcare professionals who had participated in the FORVAD Trial. Interviews explored participants’ experiences of the FORVAD trial. A rapid qualitative analysis was conducted, informed by Normalisation Process Theory. Results Four main themes were generated in the data analysis: (1) individual vs. community equipoise; (2) trial set-up and delivery; (3) identifying and approaching patients; and (4) timing of randomisation. The objectives of the FORVAD trial made sense to participants and they supported the idea that there was clinical or collective equipoise regarding the two FORVAD interventions; however, many surgeons had treatment preferences and lacked individual equipoise. The site which had most recruitment success had adopted a more structured process for identification and recruitment of patients, whereas other sites that adopted more “ad hoc” screening strategies struggled to identify patients. Randomisation on the day of surgery caused both medico-legal and practical concerns at some sites. Conclusions Organisation and implementation of a surgical trial in neurosurgery is complex and presents many challenges. Sites often reported low recruitment and discussed the logistical issues of conducting a complex surgical RCT. Future trials in neurosurgery may need to offer more flexibility and time during set-up to maximise opportunities for larger recruitment numbers. Rapid qualitative analysis informed by Normalisation Process Theory was able to quickly identify key issues with trial implementation so rapid qualitative analysis may be a useful approach for teams conducting qualitative research in trials.
