Platinum and etoposide chemotherapy, durvalumab with thoracic radiotherapy in the first-line treatment of patients with extensive-stage small-cell lung cancer: CHEST-RT (TROG 20.01) Trial – protocol for a phase II study

Background
Trans Tasman Radiation Oncology Group 20.01 CHEST-RT (Chemotherapy and Immunotherapy in Extensive Stage Small cell with Thoracic Radiotherapy) is a single-arm, open-label, prospective, multicentre phase II trial study that aims to establish the safety, feasibility and describe the efficacy of incorporating thoracic radiotherapy (TRT) (concurrent or sequential) to chemotherapy and immunotherapy in patients with extensive-stage small-cell lung cancer.

Methods
A single arm of up to 30 evaluable participants given TRT concurrent or sequentially with chemoimmunotherapy will be enrolled. Participants should commence radiotherapy with cycle 3 or cycle 4 of chemotherapy. Those not suitable for concurrent radiotherapy due to large tumour volumes may receive sequential radiotherapy. Accounting for a 15% non-evaluable rate, up to 35 participants will be enrolled. An independent data and safety monitoring committee will review the data and assess safety and feasibility. Progression to a phase III trial would be considered feasible if ≤20% of participants experienced ≥grade 3 oesophageal toxicity and ≤10% experienced ≥grade 3 pneumonitis. This approach would be considered feasible if there is ≤20% treatment discontinuation of systemic therapy secondary to radiation toxicities and ≥75% of participants have tumour volumes that can be safely treated to a dose of 30 Gy in 10 fractions. The primary outcome of the trial is safety and feasibility, and survival and responses will be assessed as secondary endpoints. A predefined subgroup analysis of toxicity will be performed on group 1 (concurrent TRT) versus group 2 participants (consolidation TRT).

Ethics and dissemination
This study was approved by the Peter MacCallum Human Research Ethics Committee (HREC/73189/PMCC-2021). The protocol, technical and clinical data will be disseminated by conference presentations and publications. Any modifications to the protocol will be formally documented by administrative letters and will be submitted to the approving HREC for review and approval.

Longitudinal study of infants born preterm (<33 weeks) or with a very low birth weight in the Ile de France region of France (SEV-IDF programme): cohort profile

Purpose
The SEV-IDF programme aims to track infants born before 33 weeks of gestation, with very low birth weight (VLBW), neonatal encephalopathy or severe birth anomalies and perinatal disease. It employs an open, prospective, multicentric, population-based cohort approach. This report aims to describe the methodology employed to establish and manage the programme, details regarding follow-up procedures, baseline characteristics of the included infants, and highlights new research opportunities emerging from the “Suivi des Enfants Vulnérables d’Ile-de-France” (SEV-IDF) programme.

Participants
The programme aims to (1) detect developmental anomalies early, (2) improve prevention using standardised data, (3) optimise follow-up care and (4) support multidisciplinary research.
Eligible participants are infants alive at discharge from the 59 maternities with a neonatal unit of the Île-de-France (IDF) region (France). A network of 567 trained physicians monitors the children’s development at 4 months, 1 and 2 years of corrected age, and 3, 4, 5, 6 and 7 years of age. Collected data include sociodemographic, pregnancy and neonatal characteristics, and standardised child development scores.

Findings to date
The programme enrolled 21 175 participants between 2016 and 2023, with 16 461 (77.7%) having a gestational age less than 33 weeks, 1916 (9.0%) others having VLBW, 1525 (7.2%) having encephalopathy and 1273 (6.0%) having another severe birth anomaly.

Future plans
The collected data will enable the SEV-IDF scientific committee to describe high-risk infants in the IDF region, design evidence-based campaigns to improve the quality and effectiveness of the follow-up as well as conduct research on developmental anomalies in these high-risk infants. Ongoing research currently focuses on anticipating loss to follow-up and early detection of developmental anomalies.

Exploring tuberculosis patients preferences for AI-assisted remote health management services in China: a protocol for a discrete choice experiment

Introduction
Effective health management is critical for patients with tuberculosis (TB), especially given the need for long-term treatment adherence and continuous monitoring. Artificial intelligence (AI)-assisted remote health management services offer a promising solution to increase patient engagement, optimise follow-up and improve treatment outcomes. However, little research has explored TB patients’ preferences for these services, and no discrete choice experiment (DCE) has systematically investigated how they make trade-offs between different service attributes. This study aims to (1) identify key attributes of AI-assisted remote health management services that influence TB patients’ choices, (2) assess how patients with TB evaluate trade-offs between different service options using a DCE and (3) examine whether preferences vary by sociodemographic characteristics and health system factors.

Methods and analysis
Six attributes were identified through a literature review, focus group discussions and expert consultations. A fractional factorial design was used to generate choice sets while maintaining statistical efficiency and minimising respondent burden. The DCE will be analysed using a multinomial logit model to estimate average preferences. A mixed logit model will be applied to explore preference heterogeneity among participants, incorporating interaction terms with sociodemographic and attitudinal variables. Stratified and latent class analyses will also be considered to further investigate sources of heterogeneity.

Ethics and dissemination
This study complies with the Declaration of Helsinki and has been approved by the Ethics Committee of Wuhan Pulmonary Hospital. All participant data will remain anonymous, and individuals may withdraw from the study at any time. The findings will inform the development of patient-centred AI-assisted TB management strategies and contribute to broader policy discussions on AI integration in TB care. The results will be disseminated through peer-reviewed journal publications, policy briefs, conferences and online platforms.

Use of an electronic medication management application to support Pharmacists Review to Optimise Medicines in Residential Aged Care (PROMPT-RC): a study protocol for a parallel cluster randomised controlled trial

Introduction
Most older adults living in residential aged care facilities (RACFs) have at least one marker of potentially suboptimal prescribing. Pharmacists play a crucial role in medication management, with their effectiveness enhanced by using computerised decision support tools. The Pharmacists Review to Optimise Medicines in Residential Aged Care (PROMPT-RC) study aims to optimise medicine use by providing pharmacists in RACFs with an electronic medicine management app with integrated decision support (AusTAPER App/Pathway) to use as part of medication reviews they undertake.

Methods and analysis
The PROMPT-RC study is a parallel cluster randomised controlled trial design involving Australian RACFs. It will assess if pharmacists’ use of the AusTAPER App/Pathway for medication reviews improves medication regimens for RACF residents compared with usual care. Pharmacists in RACFs randomised to the intervention arm will be trained to use the AusTAPER App/Pathway, which flags potentially inappropriate medicines (PIMs) across a person’s entire medicine regimen. Pharmacists in RACFs randomised to the control arm will not have access to the AusTAPER App/Pathway—they will continue to provide usual care. The primary outcome is the difference in the number of regular medicines between treatment arms at 12 months. Secondary outcomes will measure the number of regular and pro re nata medicines, PIMs, medicine administration times, medicine regimen complexity, use of antipsychotics, antidepressants, and benzodiazepines, quality of life, mortality, instances of physical restraint, and the number of falls, hospitalisations and general practitioner/health professional visits. The cost-effectiveness of the AusTAPER App/Pathway compared with usual care will be calculated. Data collection will occur at baseline, 3, 6, 9 and 12 months postrandomisation and 3 and 6 months prebaseline. We aim to recruit 668 participants to adjust for an estimated 10% loss to follow-up, giving 334 participants in each arm. Data analysis will follow an intention-to-treat approach using a linear mixed model.

Ethics and dissemination
Ethical approval was obtained from The University of Western Australia Human Research Ethics Committee (Reference: 2024/ET000525; approved 14 August 2024). Reciprocal approval was also obtained in other states. This study is registered on the Australian New Zealand Clinical Trials Registry (https://anzctr.org.au). Trial findings will be disseminated through national and international peer-reviewed publications and conferences.

Lesion-Network Mapping of Poststroke Depressive Symptoms: Evidence From Two Prospective Ischemic Stroke Cohorts

Stroke, Ahead of Print. BACKGROUND:Poststroke depression affects up to one-third of stroke survivors, significantly impacting recovery and quality of life. However, its pathophysiology remains unclear.METHODS:We analyzed 2 independent, prospective ischemic stroke cohorts (PROSCIS-B [Prospective Cohort of Incident Stroke Berlin] and BAPTISe [Biomarkers and Perfusion-Training-Induced Changes After Stroke]; n=377) enrolled at the Charité Hospital, Germany, to identify brain regions and networks associated with depressive symptoms poststroke. Lesion-symptom mapping assessed associations between lesion location and depressive symptoms measured by the Center for Epidemiological Studies Depression Scale at 6 (BAPTISe) or 12 (PROSCIS-B) months poststroke. Lesion-network mapping evaluated lesion connectivity with brain networks. A mixed-effects model, including cohort as a random effect, assessed the relationship between network similarity (Pearson correlation) and Center for Epidemiological Studies Depression Scale scores. Dice coefficients (DC) quantified spatial overlap with canonical resting-state networks.RESULTS:Lesion-symptom mapping showed no significant associations between lesion location and depressive symptoms. In contrast, lesion-network mapping revealed that lesion connectivity to brain regions including the frontal pole, middle and inferior frontal gyri, inferior temporal gyrus, supramarginal gyrus, angular gyrus, frontal orbital cortex, and thalamus weakly correlated with Center for Epidemiological Studies Depression Scale scores (β, 11.4 [95%CI, 1.8–21.1];P=0.02). These regions overlapped with the frontoparietal (DC=0.28), salience (DC=0.27), and default mode (DC=0.20) networks, as well as a published depression circuit (DC=0.43). However, these findings did not replicate across data sets.CONCLUSIONS:Lesion location alone was not associated with poststroke depression. However, connectivity-based analyses implicated disruption of large-scale brain networks in the development of depressive symptoms. The failure to validate this association across data sets underscores the need for further studies with more comparable patient populations—particularly in terms of stroke severity and harmonized assessment time-points—to confirm these findings and their clinical relevance.REGISTRATION:URL:https://www.clinicaltrials.gov; Unique identifier: NCT01363856.

Rare cause of liver lesion in a patient with ulcerative colitis

Clinical presentation A 26-year-old man was diagnosed with a 4-month history of ulcerative colitis. At the time of diagnosis, an abdominal CT showed a thickened colorectum (figure 1A) and a normal liver (figure 1B). He was started on mesalazine 4 g/day and received this for approximately 2 months without therapeutic benefit. He clinically deteriorated and was admitted to the hospital with a fever of up to 38.5°C daily, abdominal pain and diarrhoea. Laboratory findings revealed significantly elevated white blood cells (13.86×109/L), C reactive protein (69.5 mg/L) and elevated liver enzymes: aspartate aminotransferase 245 U/L, alanine aminotransferase 368 U/L (normal

Gene score to quantify systemic inflammation in patients with acutely decompensated cirrhosis

Background and aims
Quantifying systemic inflammation (SI) in acutely decompensated cirrhosis (ADC) is of major importance because SI is a driver of the most severe forms of ADC, including acute-on-chronic liver failure (ACLF). Blood biomarkers of SI already evaluated in ADC failed to appropriately assess SI in ADC. We aimed to investigate whether gene expression related to circulating immune cells could quantify SI in ADC.

Methods
Standard biomarkers (white cell count, C reactive protein, cytokines) and genome-wide RNA expression (RNA-sequencing) were obtained in blood from 700 patients with ADC at the time of their hospital admission. A composite score based on standard biomarkers of SI (Chronic Liver Failure-Standard Biomarkers Composite (CLIF-SBC) score) and a gene score (CLIF-Systemic Inflammation Gene (SIG) score) composed of the 28 top differentially expressed immune cell-related genes in the comparison between high-severity and low-severity clinical phenotypes were computed. Among the 700 patients, the CLIF-SIG score was repeated once during follow-up in 375 patients, and 3 times or more in 46 patients.

Results
The CLIF-SIG score was more accurate in reflecting clinical severity induced by SI than the CLIF-SBC score (area under the curve 0.803 vs 0.658). A CLIF-SIG score of 0.386 (Youden Index) was the best cut-off level discriminating patients with poor outcomes from the others, in all clinical scenarios. Sequential measurement of the CLIF-SIG score showed that 78% of patients were admitted at the peak or descending part of the SI-wave. ACLF developed during hospitalisation in 80% of patients with a CLIF-SIG score >0.386 on admission.

Conclusions
In patients with ADC, the CLIF-SIG score is an accurate estimator of SI, clinical course severity and prognosis.

GRACE: protocol for a UK, secondary care, multicentre, assessor-blinded randomised controlled trial with a non-inferiority comparison to evaluate graduated compression stockings as an adjunct to extended duration pharmacological thromboprophylaxis for venous thromboembolism prevention

Introduction
Venous thromboembolism (VTE) occurs when a blood clot forms in a vein. It is comprised of deep vein thrombosis (DVT) and pulmonary embolism and can be potentially life-threatening. Patients undergoing surgery are at increased risk of developing VTE within hospital admission and 90 days after hospital discharge are collectively known as hospital-acquired thrombosis (HAT). Without the use of thromboprophylaxis, the untreated risk of VTE is reported to be as high as 40–60% in those undergoing major orthopaedic procedures and around 15–40% in the general surgical population.
HAT accounts for around 12 000 deaths per year in the UK. For patients undergoing surgery, there is good evidence for the use of thromboprophylaxis to prevent VTE.
Thromboprophylaxis is available in both pharmacological and mechanical forms. While there is a huge body of evidence demonstrating that pharmacological thromboprophylaxis significantly reduces VTE by 30–65%, the benefit of graduated compression stockings (GCS) has been called into question. The GRACE study (Graduated Compression stocking as an adjunct to Extended duration pharmacological thromboprophylaxis for venous thromboembolism prevention) aims to evaluate the adjuvant benefit of GCS in addition to extended duration pharmacological thromboprophylaxis (EDPTP) for elective surgical patients at highest risk of VTE.

Methods and analysis
GRACE is a pragmatic, multicentre randomised trial of adults undergoing surgery who are at high risk of VTE. Participants are randomised into a 1:1 ratio to either EDPTP and compression stockings (control arm) or EDPTP (intervention arm). Following randomisation, participants will undergo surgery and be followed up centrally at 7, 21–35 and 90 days after their procedure. All participants will be offered a bilateral full lower limb duplex scan at 21–35 days post procedure to capture any asymptomatic DVT.
The trial aims to randomise 8608 participants from around 50 National Health Service (NHS) and non-NHS sites in the UK over a 24-month period. The primary endpoint is any imaging-confirmed incidence of VTE within 90 days of surgery.

Ethics and dissemination
On 20 December 2023, GRACE received favourable ethical approval from the Wales Research Ethics Committee 3 Cardiff (23/WA/0350) and the Health Research Authority (IRAS 333539). The results of the study will be disseminated via peer-reviewed publications, presentation at national and international conferences and to study participants via electronic newsletter and social media channels.

Neuropsychiatric complications 3-4 years after stroke: a population-based study of fatigue, depression and cognition

Objectives
To study the prevalence of and interplay between common neuropsychiatric sequelae 3–4 years after onset of first-ever stroke—specifically post-stroke fatigue (PSF), post-stroke depression (PSD) and post-stroke cognitive impairment (PSCI).

Design
Population-based cohort study.

Setting
Catchment area of a Swedish University Hospital.

Participants
We recruited individuals with first-ever ischaemic stroke or intracerebral haemorrhage in the initial cohort; 151 of these died prior to follow-up and 47 (12%) were lost to detailed follow-up. We followed up 202 individuals with median age: 72 (IQR 65–79), 40% female, either in clinic, via home visits or via telephone.

Primary and secondary outcome measures
Primary outcome measures included PSF (Fatigue Assessment Scale), PSD (Patient Health Questionnaire-9) and PSCI (Montreal Cognitive Assessment). Secondary outcome measures included dependency in activities of daily living (ADL; Barthel Index), health-related quality of life (HRQoL; Short-Form Questionnaire-36, EuroQoL-5D and Stroke Impact Scale) and stroke severity (National Institutes of Health Stroke Scale (NIHSS)).

Results
Significant PSF was present in 46/195 (24%), PSD in 21/191 (11%), and PSCI in 93/173 (54%) respondents. Among 169 participants with available data for all three domains, 100 (59%) had impairment in at least one domain. Participants with PSCI were older than those without (median: 75 vs 67 years; p

Association between left atrial appendage volume and atrial fibrillation recurrence after catheter ablation: a systematic review and meta-analysis

Objectives
To evaluate the association between left atrial appendage volume (LAAV) and atrial fibrillation (AF) recurrence after catheter ablation (CA) and explore the potential mechanism.

Design
Systematic review and meta-analysis.

Data sources
PubMed, EMBASE, Web of Science and Cochrane Library databases were searched systematically from inception through 28 September 2024 to identify relevant studies.

Eligibility criteria
Observational studies that estimated the association between LAAV and AF recurrence.

Data extraction and synthesis
Two independent investigators screened studies for inclusion and extracted data. Statistical heterogeneity was assessed using the Cochrane Q-test and I², with p 50% indicating significant heterogeneity. This study used a random-effects model to account for potential heterogeneity. The quality of the included studies was assessed using the Newcastle–Ottawa Scale (NOS), Risk of Bias in Non-randomized Studies of Interventions (ROBINS-I tool) and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Publication bias was examined through funnel plots and Egger’s test.

Result
Seventeen studies (3078 patients) were included. Meta-analysis of 11 studies suggested that LAAV was significantly associated with the risk of AF recurrence in both univariate (HR 1.06, 95%CI 1.04 to 1.08, p

Determinants of enrolment rate in 397 clinical trials for healing diabetic foot ulcers: a systematic review

Objectives
Diabetes mellitus (DM) affects over 422 million individuals globally. Diabetic foot ulcers (DFUs) stand out as a challenging complication of DM, affecting up to 34% of individuals with DM. Despite the prevalence of DFUs, clinical trials for DFUs often face slow and insufficient patient recruitment. We aimed to identify key determinants that impact subject recruitment rates in DFU clinical trials.

Design
Systematic review.

Data sources
ClinicalTrials.gov and PubMed were searched to identify DFU clinical studies published from 1 January 1990 to 9 April 2025.

Eligibility criteria
We included English-language publications of clinical trials aimed at healing DFUs that reported enrolment numbers, duration of enrolment and number of study centres.

Data extraction and synthesis
Records were extracted and subjected to two independent rounds of review by five authors (LZ, SP, RN, HL-T, and RK). Data were pooled and analysed using negative binomial regression, Kaplan-Meier methods and Cox proportional hazards models. Study enrolment and site enrolment rates, as well as time to complete study enrolment, were analysed. Between-study heterogeneity was assessed using the likelihood ratio test.

Results
397 trials involving 31 955 participants were included. On average, DFU studies enrolled 4.24 patients per month (median: 1.65). US-based studies had slower recruitment than non-US studies, with a mean enrolment rate of 1.51 patients per site per month (median: 0.58). The average time to complete enrolment was 1.28 years. Studies that employed a higher number of study sites, were conducted outside the USA, studied behavioural or dietary supplement interventions, and began enrolment more recently, were more likely to have a higher enrolment rate. Longer time to complete enrolment was associated with a larger number of study sites, trials involving at least one US site, earlier starting enrolment year, and longer follow-up duration.

Conclusions
These findings have potential practical implications for the design and conduct of future DFU trials.

Prospective multicentre randomised controlled trial to assess the clinical effectiveness of the novel CirrhoCare digital therapeutic management system: a study protocol

Introduction
Liver cirrhosis accounts for over 10 000 deaths in the UK each year with a total loss of 60 000 quality-adjusted life-years. There is a substantial cost to the NHS of £4.5 billion, with new liver-related decompensation events accounting for the majority of this. Following an acute cirrhosis decompensating event, there is a significant risk of hospital readmission with 90-day readmission rates as high as 53%. Current care in the UK is reactive and patients are often only readmitted when they have presented acutely as an emergency with significant decompensation.

Methods and analysis
CirrhoCare is a prospective, multicentre, randomised controlled trial comparing the CirrhoCare management system with standard-of-care for high-risk cirrhosis patients who have been discharged following an admission with acute decompensation. The CirrhoCare management system comprises a novel digital platform for use in a patient’s home, designed to proactively detect the first signs of new decompensation in patients with established cirrhosis, discharged to the community. This enables a clinician to instigate early community-based care or, if needed, to triage the patient for hospital interventions.
214 patients will be recruited to the CirrhoCare trial from at least 12 UK centres. Patients will be randomised on a 1:1 ratio allocation to the CirrhoCare Management System or standard of care. Participants who are randomised to CirrhoCare will receive a CirrhoCare health kit comprising a smart watch, smart phone with enabled SIM (Subscriber Identity Module) network card, blood pressure monitor, weighing scales and thermometer. Participants will take measurements every morning Monday to Friday and will be followed up for 90 days postdischarge.
The primary objective of this study is to assess the clinical effectiveness of the CirrhoCare digital management system. We hypothesise that its early community-based intervention will reduce the number of unplanned hospital interventions and admissions and prevent liver-related complications when compared with standard-of-care management.

Ethics and dissemination
CirrhoCare is a National Institute for Health and Care Research-funded study (NCT06223893). The study has UK Research Ethics Committee and Health Research Authority (HRA) approvals, with approval granted by the HRA and Health and Care Research Wales committee. The results of this study will be published in peer review journals, disseminated at international conferences as well as established Patient and Public Involvement and Engagement networks.

Trial registration number
ISRCTN11380842.
