Por: Shanmugasundaram · S. · Shewade · H. D. · Srinivasan · R. · Frederick · A. · Sabarinathan · R. · Harish · P. · Balu · D. · Melfha · J. M. · Gayathri · K. · Vijayaprabha · R. · Jeyakumar · A. · Kabir · D. · Eraivan · M. · Bhatnagar · T. · Murhekar · M. V.
Objectives

To develop predictive models for early and overall tuberculosis (TB) deaths for prospective use at TB diagnosis in resource-constrained TB programme settings.

Design

Statewide cohort study using routinely captured secondary data.

Setting

With the majority of TB deaths being early (within 2 months), India’s TB programme’s information management system (Ni-kshay)-dependent death prediction models (using age, gender, TB site, previous treatment, microbiological confirmation, HIV, diabetes and bank account availability) are not feasible for prospective use, as few variables are captured at diagnosis. Utilising routinely captured triage variables for severe illness at diagnosis (body mass index, pedal oedema, respiratory rate, oxygen saturation and ability to stand without support) from an ongoing statewide and state-specific differentiated TB care initiative to reduce TB deaths in Tamil Nadu state (southern India, 80 million population with 0.1 million annual notifications), robust models for prospective use were developed.

Participants

Adults (aged ≥15 years) with TB (not known to be drug-resistant at diagnosis) that were notified from public facilities of Tamil Nadu from July 2022 to June 2023.

Outcome measures

Early and overall (within 12 months of notification) TB deaths. Area under the receiver operating characteristic curve (AUC) was used to assess accuracy of models built using modified Poisson regression.

Results

Among 55 971 adults, the overall death rate was 7.4%, and 67.9% of the deaths were early. In predicting overall deaths, accuracy of the model using all Ni-kshay variables (AUC 0.716 (95% CI 0.707 to 0.725)) was as good as the model using triage variables for severe illness only (AUC 0.701 (95% CI 0.691 to 0.711)). To the latter, adding potentially capturable Ni-kshay variables at diagnosis (age, gender, TB site, previous treatment and microbiological confirmation) significantly improved model accuracy (AUC 0.754 (95% CI 0.745 to 0.763)). Further addition of remaining Ni-kshay variables did not improve accuracy significantly. Death prediction equations were generated for these models.

Conclusion

Simple and easily measurable triage variables for severe illness should be routinely captured at TB diagnosis. A death prediction calculator (http://44.208.93.99/) based on these variables (specifically triage variables for severe illness combined with age, gender, TB site, previous treatment and microbiological confirmation) may be used by Indian states and high TB burden countries seeking scalable, data-driven interventions to reduce TB deaths.

Ventilation strategies and outcomes after out-of-hospital cardiac arrest: protocol for a pre-planned sub-analysis of the STEPCARE trial

Por: Battaglini · D. · Gualdi · F. · Cammarota · G. · McGuigan · P. J. · Thomas · M. · Skrifvars · M. B. · Niemelä · V. H. · Reinikainen · M. · Bass · F. · Young · P. J. · Lilja · G. · Dankiewicz · J. · Hammond · N. E. · Hästbacka · J. · Levin · H. · Moseby-Knappe · M. · Saxena · M. · Tia
Introduction

After resuscitation from out of hospital cardiac arrest (OHCA), mechanical ventilation (MV) and respiratory management are fundamental to support patients in the intensive care unit (ICU) and to minimise secondary brain injury. Best practices for MV and association with clinical outcomes in patients with OHCA remain unclear.

Methods and analysis

This protocol describes a pre-planned respiratory-focused series of sub-analyses within the Sedation, Temperature and Pressure after Cardiac Arrest and Resuscitation (STEPCARE) trial, an ongoing interventional study evaluating 6-month mortality after randomisation in patients admitted to ICUs following OHCA. The primary aim is to describe real-world ventilator settings and gas-exchange targets during the first 72 hours after ICU admission in patients receiving invasive mechanical ventilation after OHCA. Secondary aims include to estimate the incidence of respiratory complications during ICU stay (eg, ventilator-associated pneumonia, acute respiratory distress syndrome, barotrauma); and to explore the association between early ventilator settings/gas-exchange parameters and 6-month outcomes (mortality and neurological status). Exploratory aim is to characterise weaning and extubation practices, including timing and failure rates.

Eligible patients will include adult STEPCARE participants receiving invasive MV after return of spontaneous circulation with available respiratory data recorded within the STEPCARE database.

Data collected in the STEPCARE trial that will be analysed include patients’ prehospital characteristics; clinical examination at hospital admission and at ICU admission; ventilator settings and arterial blood gases recorded at predefined time points during ICU stay. In particular: MV setting (mode, tidal volume, positive end-expiratory pressure, fraction of inspired oxygen, tidal volume, mechanical power, plateau/driving pressures), gas-exchange values (arterial partial pressure of oxygen and carbon dioxide, pH, arterial saturation of oxygen), timing of measurements and the occurrence/timing of respiratory complications and weaning outcomes.

Ethics and dissemination

The STEPCARE study has been approved by the regional ethics committee at Lund University (Dnr 2022-02425-01, Approved IRB on 2022-06-18) and by all ethics boards in the participating countries. No additional ethical approval is required for this predefined secondary analysis, as no further data collection or interventions will be performed. Findings will be disseminated through publication in peer-reviewed journals and, where appropriate, conference abstracts and presentations. Patients and the public were not involved.

Association between the use of anti-herpetic drugs and subsequent initiation of Alzheimers disease drug treatment: Dutch population-based inception cohort study

Por: Alghamdi · A. · Balafas · S. · Bos · J. H. J. · van Munster · B. C. · Rafie · K. · Dolga · A. M. · Hak · E.
Objectives

To examine whether exposure to anti-herpetic drugs (AHDs: acyclovir, valacyclovir, famciclovir) is associated with reduced risk of Alzheimer’s disease (AD) treatment initiation.

Design

Population-based retrospective matched cohort study.

Setting

University Groningen community pharmacy database IADB.nl, covering approximately 125 Dutch pharmacies (1994–2024).

Participants

262 757 adults aged 50–80 years without prior dementia or AD treatment. Exposed individuals with antiherpetic prescriptions (n=23 887) were matched 1:10 to unexposed controls (n=238 870) by age, sex and calendar time.

Intervention

AHDs: acyclovir, valacyclovir, famciclovir.

Main outcome measures

Initiation of AD drug treatment, defined as at least two prescriptions for rivastigmine, donepezil, galantamine or memantine within 1 year. Cox proportional hazards models estimated HRs with 95% CIs, adjusted for comorbidities and medications. Analyses were stratified by period (1994–2018 vs 2019–2024) and drug type.

Results

During follow-up, 2495 participants initiated AD treatment. The age of the participants was 65 (SD 9), and 59% were female. Any AHD exposure was associated with 90% reduced hazard of AD treatment (HR 0.09, 95% CI 0.07 to 0.13, p

Conclusions

AHD exposure was consistently associated with markedly lower risk of AD treatment initiation, with similar findings observed in recent years. These findings support the hypothesis that herpesvirus reactivation may contribute to AD pathogenesis and suggest antiviral therapy could have preventive implications. Confirmation through prospective studies and randomised trials is needed.

Revisiting the role of structural connectivity-based parcellation in thalamic nuclei segmentation: Benchmarking against recent state-of-the-art methods

by Daniel H. Nguyen, Debottama Das, Ali Bilgin, Dianne Patterson, Matthew Hook, Chris Butson, Alberto Cacciola, Vinod Kumar Jangir, Manojkumar Saranathan

Leveraging diffusion tractography, connectivity-based parcellation (CBP) is one of the oldest methods for thalamic nuclei segmentation. The goal of this work was to reassess CBP using higher spatial resolution diffusion MRI data and reconstruction algorithms, and to compare it with recent state-of-the-art methods for thalamic nuclei segmentation. Furthermore, these methods were systematically evaluated against three histological atlases and one functional MRI–based atlas to examine their relative anatomical similarities and differences. High resolution diffusion and T1-weighted MRI data from 67 healthy individuals in the Human Connectome Project Young Adult database were analyzed. CBP was performed using probabilistic tractography with cortical targets derived from combining labels of the Human Connectome Project Multi-Modal Parcellation 1.0 atlas into 8, 11, and 23 regions. Results were compared against three recent methods: orientation distribution function clustering (ODF), track density imaging (TDI), and structural MRI-based segmentation. Group level analyses were conducted in the Montreal Neurological Institute space, and Dice overlap coefficients were calculated using four atlases (three histological, one functional). CBP results using newer data and methods were still remarkably similar to the original CBP parcellation results. Across atlases, a consistent hierarchy was observed: HIPS-THOMAS performed best, followed by TDI, ODF, and CBP (Kendall’s W = 1.00, p = 0.007). Histological atlases showed strong mutual agreement (Pearson r = 0.71–0.85), whereas the Zhang atlas demonstrated lower concordance (Pearson r = 0.51–0.63). Despite methodological advances, CBP remains constrained in its ability to delineate thalamic nuclei with histological accuracy. By contrast, structural and diffusion microstructural approaches provided better nuclear localization. These findings highlight the need for hybrid workflows that integrate structural and diffusion-based information to enable more reliable thalamic segmentation for neuroscience research.

Add-on tocilizumab versus placebo for resistant major depression in psychiatric outpatients with low-grade inflammation in a tertiary public hospital in Southern Brazil: randomised triple-blind clinical trial protocol

Por: Portal · P. H. G. · Peixoto · G. N. · de Matos · M. R. · da Silva · L. C. N. · Alexandrino · G. B. · Dutra · P. H. G. · Carniel · B. P. · da Rocha · N. S.
Introduction

Emerging evidence supports a role for interleukin 6 (IL-6), a pro-inflammatory cytokine, in the pathogenesis of treatment-resistant major depressive disorder (TRD). However, interventional studies targeting IL-6 in this population remain scarce. Tocilizumab is a humanised monoclonal antibody that inhibits IL-6 signalling and is approved for the treatment of autoimmune conditions such as rheumatoid arthritis. The primary objective of this study is to examine whether IL-6 inhibition via tocilizumab can impact depressive symptoms, inflammation-related biomarkers and cognition in patients with TRD. A secondary objective is to compare the biological profiles of patients with TRD with elevated inflammation to those of healthy controls.

Methods and analysis

This is a proof-of-concept, randomised, parallel-group, triple-blind, placebo-controlled clinical trial. 22 adult outpatients diagnosed with TRD and evidence of low-grade inflammation (serum C reactive protein≥3 mg/L) will be randomised (1:1) to receive either one intravenous infusion of tocilizumab (8 mg/kg; maximum 800 mg) or normal saline, administered as an add-on to their ongoing treatment. Psychiatric, cognitive and biomarker assessments will be performed at baseline and at follow-up visits on days 7, 14 and 28 post-infusion. Additionally, 10 healthy controls with no psychiatric history will undergo the same baseline assessments for biomarker comparison.

Ethics and dissemination

The study has been approved by the Research Ethics Committee of the Hospital de Clínicas de Porto Alegre (Project number: 2025-0245, CAAE: 88904825.7.0000.5327). Findings will be disseminated through peer-reviewed publications, scientific meetings and, on request, lay summaries for participants.

Effect of a culturally adapted heart-healthy diet with phytosterols and/or krill oil on lipid-related outcomes in familial hypercholesterolaemia: protocol for a multicentre randomised controlled trial in Brazil

Introduction

An affordable heart-healthy dietary approach is essential for the management of familial hypercholesterolaemia (FH); however, the optimal dietary pattern and the role of adjunctive nutrient supplementation remain uncertain. This study aims to evaluate the effects of the Brazilian Cardioprotective Diet (DICA Br), adapted from the Portfolio Diet, with or without phytosterol and/or krill oil supplementation in individuals with probable or definite FH according to the Dutch Lipid Clinic Network (Dutch MEDPED) criteria.

Methods and analysis

The DICA-FH study is a national, multicentre, randomised, factorial, parallel-group, superiority, placebo-controlled clinical trial with a 1:1:1:1 allocation ratio. Participants aged ≥16 years receiving age-appropriate lipid-lowering therapy will be randomised into four groups: (1) adapted cardioprotective diet (DICA-FH) plus phytosterol placebo and krill oil placebo; (2) DICA-FH plus phytosterol 2 g/day and krill oil placebo; (3) DICA-FH plus phytosterol placebo and krill oil 2 g/day or (4) DICA-FH plus phytosterol 2 g/day and krill oil 2 g/day. All participants will undergo whole-genome sequencing and receive appropriate genetic counselling. Primary outcomes will be means of low-density lipoprotein cholesterol and lipoprotein(a) levels after 120 days. Secondary outcomes will include additional lipid biomarkers, adherence to protocol and adverse events. The planned sample size is 300 participants. Follow-up is expected to conclude in July 2026.

Ethics and dissemination

This study was registered under CAAE 65549622.2.1001.0060 and received ethical approval from the Hcor Research Ethics Committee (approval number 5.805.072) and the Brazilian National Research Ethics Commission (CONEP; approval number 6.864.951). Written informed consent will be obtained from all participants prior to enrolment. The study findings will be disseminated through peer-reviewed publications, scientific conferences and channels aimed at the general public.

Minocycline hydrochloride ointment-assisted periodontal treatment of stage III/IV periodontitis associated with type 2 diabetes mellitus targeting Chinese people: study protocol for a randomised controlled trial

Por: Zhao · H. · Lin · S. · He · L. · Zhen · M. · Yang · G. · Wang · X. · Cao · J. · Li · Y. · Hou · J. · Xu · L. · Meng · H. · Liu · K.
Introduction

Scaling and root planing (SRP) combined with adjunctive antibiotic therapy is widely adopted in the management of periodontitis in patients with type 2 diabetes mellitus (T2DM), with the aims of ameliorating glycaemic control, alleviating local inflammation and facilitating periodontal tissue regeneration. As a topically administered adjunctive antibiotic for periodontal treatment, minocycline hydrochloride (MH) ointment has shown favourable clinical efficacy in systemically healthy patients with periodontitis. However, robust evidence supporting its clinical efficacy and potential glycaemic-improving effects in patients with periodontitis complicated by T2DM remains limited. The present study is designed to test the null hypothesis that no significant differences in clinical outcomes exist between SRP combined with MH and SRP alone in the management of periodontitis among patients with T2DM, with its primary objective to investigate whether MH as an SRP adjunct confers superior clinical benefits to SRP alone.

Methods and analysis

We will conduct a randomised, single-blind, placebo-controlled clinical trial. 56 patients with T2DM-associated stage III/IV periodontitis will be recruited from the Department of Periodontology, Peking University School and Hospital of Stomatology, Beijing, China. Eligible participants will be randomised into two groups: the experimental group will undergo SRP combined with topically administered MH ointment and the control group will undergo SRP with a matched placebo. The primary outcomes will include probing depth (PD) changes at periodontal pocket sites with a baseline PD ≥6 mm at 6 months post-baseline, with a specific focus on the percentage of such sites with PD reduced to ≤5 mm. The secondary outcomes will comprise PD changes at pocket sites with a baseline PD ≥5 mm at 6 months post-baseline, as well as clinical attachment loss, the plaque index, bleeding index, the levels of IL-1β, IL-17, calprotectin and insulin levels in gingival crevicular fluid and serum, complete blood count, blood biochemistry, including glycated haemoglobin levels, and the composition of subgingival plaques at baseline, and 2 and 6 months post-baseline.

Ethics and dissemination

This study was approved by the Ethics Committee of Peking University School and Hospital of Stomatology (PKUSSIRB-2024102139b). Results will be published in a peer-reviewed scientific journal.

Association of 24-hour movement guideline adherence with mental health symptoms among Colombian university students: a cross-sectional study

Objective

This study aimed to determine the associations between adherence to the 24-hour movement guidelines and symptoms of anxiety and depression among Colombian university students.

Study design

Cross-sectional study.

Participants

1125 individuals (mean age 20.2±2.5 years; 56.7% female).

Setting

Students sampled from a single public university.

Primary and secondary outcome measures

Participants completed validated self-report instruments: the International Physical Activity Questionnaire-Short Form to assess physical activity (PA), sedentary behaviour (SB) and the Pittsburgh Sleep Quality Index to assess sleep duration. Symptoms of depression and anxiety were measured using the Hospital Anxiety and Depression Scale, with a score of ≥11 used to classify elevated symptoms. Binary logistic regression models were used to estimate associations between adherence to the 24-hour movement guidelines (meeting all three, two, one or none) and mental health outcomes, adjusting for potential confounders.

Results

Only 15.5% of students met all three components of the 24-hour movement guidelines. Meeting a greater number of components was significantly associated with lower odds of depressive and anxiety symptoms. In fully adjusted analyses, students who met all three guidelines were less likely to report anxiety symptoms (OR=0.26; 95%CI 0.13 to 0.54) and depressive symptoms (OR=0.42; 95%CI 0.22 to 0.79) compared with those who met none. Among individual behaviours, sufficient PA and adequate sleep were independently associated with lower odds of both outcomes, whereas high SB was associated with higher odds of elevated symptoms.

Conclusions

In this cross-sectional study, adherence to a greater number of 24-hour movement guideline components was associated with lower levels of anxiety and depressive symptoms in a graded manner. However, the cross-sectional design precludes inference regarding directionality or causality, and bidirectional associations or residual confounding remain possible. Longitudinal and interventional studies are needed to determine whether integrated daily movement behaviours influence mental health outcomes in young adults, particularly in Latin American populations.

Symptom experience of patients after total knee arthroplasty in China: a longitudinal qualitative study

Por: Wu · K. · Zhu · J. · Liu · J. · Li · N. · Li · C. · Chen · X. · Sun · H. · Zhang · H. · Liu · H.
Objective

Total knee arthroplasty (TKA) is a common and effective procedure for end-stage knee osteoarthritis, yet patients frequently encounter a complex and dynamic symptom experience during the initial period that can significantly impact their rehabilitation and quality of life. This study aimed to explore the symptom experience of patients within 6 weeks after TKA.

Design

A longitudinal qualitative study using semi-structured interviews.

Setting

This study was conducted in an orthopaedics department of a tertiary general hospital in China.

Participants

Interviews were conducted with 16 patients at 3–5 days postoperatively, 14 patients at 2 weeks postoperatively and 10 patients at 6 weeks postoperatively.

Methods

Data were collected between July 2024 and November 2024. A purposive sampling method was used to recruit patients. Data were analysed using directed content analysis, with data collection and analysis performed concurrently.

Results

Three themes and nine subthemes were identified: (1) symptom perception, including perceived complexity of symptoms, self-identity conflict due to functional limitations, activation of negative emotions and psychological adaptation and interaction and amplification effects among symptoms; (2) symptom evaluation, characterised by the dynamic cognitive reframing of symptom meaning, self-blame tendency and internalisation of responsibility and interference from social and medical information; (3) symptom coping, involving dynamic evolution of active coping strategies and self-efficacy reinforcement, temporal characteristics of passive coping patterns and rehabilitation barriers.

Conclusion

The symptom experience of patients who had TKA is complex and dynamic. Healthcare providers should implement tailored interventions based on patients’ symptom experiences at different stages to facilitate symptom management, alleviate distress and negative emotions and improve quality of life.

Accuracy of ophthalmic referral diagnoses by non-ophthalmologists in acute eye care: protocol for a systematic review and meta-analysis

Por: Cunha Gil · L. · Powis · A. · Wilson · H. · Thampy · R. · Kousha · O. · Dhawahir-Scala · F.
Introduction

Ophthalmic complaints account for a substantial proportion of presentations to emergency and acute eye care services, yet initial assessment or referral is frequently performed by non-ophthalmologist healthcare professionals. Previous single-centre studies suggest that one-third of referrals are incorrectly diagnosed, potentially delaying appropriate management of vision-threatening conditions. However, the overall magnitude of diagnostic error and patterns of misdiagnosis across healthcare settings remain unclear. This study aims to systematically review and synthesise the evidence on the diagnostic concordance of ophthalmic referral diagnoses made by non-ophthalmologists in acute eye care.

Methods and analysis

A systematic review and meta-analysis will be conducted following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols) guidance and registered with PROSPERO. MEDLINE (Ovid), Embase (Ovid) and the Cochrane CENTRAL database will be searched from inception to April 2025. Studies evaluating the diagnostic accuracy of referrals made by non-ophthalmologist healthcare professionals in emergency or acute eye care settings will be included. Two reviewers will independently screen studies, extract data and assess risk of bias using the QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies-2) framework adapted for referral-diagnosis studies. The primary outcome will be diagnostic concordance between referral and final ophthalmologist diagnosis. Where appropriate, pooled concordance proportions will be synthesised using a random-effects meta-analysis. Condition-specific 2x2 diagnostic accuracy analyses will only be undertaken where valid binary target conditions and sufficient denominators are reported. Heterogeneity will be assessed using Cochran’s Q test and the I² statistic with subgroup analyses exploring differences by referring clinician type and anatomical location of ophthalmic pathology.

Ethics and dissemination

Ethical approval is not required for this study as it will synthesise data from previously published studies; findings will be disseminated through publication in a peer-reviewed journal and presentation at relevant academic conferences.

DREAMSPHEN: a randomised controlled study comparing dose reduction of antipsychotics vs maintenance treatment in schizophrenia spectrum disorder after stratification based on patients psychotic phenotype - study protocol of a personalised medicine approac

Por: Berna · F. · Horowitz · M. A. · Javelot · H. · Meyer · N. · Foucher · J. R.
Introduction

The DREAMSPHEN study (Dose REduction of Antipsychotics vs. Maintenance treatment in schizophrenia after Stratification based on psychotic PHENotype) aims to compare the benefits and risks of a hyperbolic tapering method for antipsychotics to the maintenance of antipsychotics in a sample of clinically stabilised patients with schizophrenia spectrum disorder.

Methods and analysis

A sample of 288 patients will be recruited from 12 centres in France. Inclusion criteria are: diagnosis of schizophrenia spectrum disorder (according to the 5th version of the Diagnostic and Statistical Manual of mental disorders, DSM-5), minimum of 3 months remission of psychotic symptoms and in treatment with antipsychotic medication (except clozapine and long-acting antipsychotic injection). First, the psychotic phenotype of the patients (cycloid psychosis vs other psychotic phenotype) will be assessed. Then, patients will be randomised either to the maintenance of treatment (MT) or to the antipsychotics dose reduction (DR) arm. DR will follow a hyperbolic schema according to Horowitz protocol. Patients will be assessed at baseline, and every 2 months until 24 months follow-up regarding social functioning, psychotic and negative symptoms, side effects of antipsychotic medication, cognitive functioning, patient satisfaction, substance and alcohol use, and quality of life. The primary outcome will be a good social functioning after 24 months defined as a score at the Personal and Social Performance Scale >70. Secondary outcome measures will include: psychotic and negative symptoms, hospitalisation for psychotic episode, antipsychotic dose, antipsychotic side effects, withdrawal symptoms, cognitive functioning, patient’s well-being and quality of life. Safety measures will include death, admissions to psychiatric hospital, psychotic relapses and severe self-harm.

Ethics and dissemination

The DREAMSPHEN trial aims to better identify patients with psychotic disorders who are most likely to benefit from antipsychotic tapering with an aim to inform future clinical treatment guidelines for antipsychotic treatment. DREAMSPHEN V2.0 of the 14 May 2025 has received ethical approval from Comité de protection des personnes Ile de France IV (N° 2023-509558-80-00) on 17 July 2025.

Use of clips to prevent delayed post-polypectomy bleeding in non-pedunculated colorectal lesions: protocol for a systematic review and meta-analysis

Por: Wei · Y. · Zhang · S. · Mabenga · H. S. · Ngowi · B. J. · Jin · Z.
Introduction

Delayed post-polypectomy bleeding (DPPB) remains a significant complication of endoscopic resection, contributing to morbidity and increased healthcare costs. Although prophylactic clipping is widely practised to mitigate this risk, evidence from recent randomised controlled trials (RCTs) regarding its efficacy is inconsistent. This protocol outlines a systematic review and meta-analysis to evaluate the effectiveness of prophylactic clips following thermal resection.

Methods and analysis

We will conduct a comprehensive search of MEDLINE, EMBASE and the Cochrane Library from inception to 10 February 2026, to identify RCTs comparing prophylactic clips vs no clips in patients undergoing thermal endoscopic resection of non-pedunculated polyps. The primary outcome is DPPB within 30 days, defined as overt bleeding requiring medical intervention or a haemoglobin decrease ≥2 g/dL. Secondary outcomes include DPPB in proximal large (≥20 mm) lesions, perforation, post-polypectomy syndrome and procedure time. Data synthesis will use a random-effects model. Methodological quality will be assessed using the Cochrane Risk of Bias 2 tool. Publication bias will be visualised using funnel plots. We will quantify the effect of potential effect modifiers by meta-regression if appropriate. The quality of evidence will be evaluated according to the Grading of Recommendations Assessment, Development and Evaluation framework.

Ethics and dissemination

This study will not use primary data, and therefore formal ethical approval is not required. The findings will be disseminated through peer-reviewed journals and committee conferences.

Surgery or radiotherapy for early-stage cancer study protocol for an emulated target trial of radical radiotherapy versus radical cystectomy, with either following neoadjuvant chemotherapy, for organ-confined muscle-invasive bladder cancer

Por: Kagenaar · E. · Lugo-Palacios · D. G. · Bromley · H. · Aggarwal · A. · Hutchings · A. · ONeill · S. · Rachet · B. · Cresswell · J. · Choudhury · A. · Grieve · R.
Introduction

Neoadjuvant chemotherapy (NAC) followed by definitive treatment consisting of either radical radiotherapy or radical cystectomy is the recommended treatment for patients with organ-confined muscle-invasive bladder cancer (OC-MIBC). A randomised controlled trial (RCT) aimed to compare the effectiveness of radical radiotherapy and radical cystectomy but failed to recruit. Radical radiotherapy is non-invasive and organ-preserving, and observational studies have suggested this treatment may be associated with similar outcomes compared with radical cystectomy. However, in these observational studies, the risk of confounding was high, and they did not consider the receipt of NAC. The surgery or radiotherapy (SORT) for the early-stage cancer study will assess the comparative effectiveness and cost-effectiveness of either radical cystectomy or radical radiotherapy, both after NAC for OC-MIBC. We will use a target trial emulation approach to reduce the risk of bias when assessing comparative effectiveness from observational data.

Methods and analysis

The SORT study will use UK’s National Cancer Registry to identify individuals diagnosed with urothelial OC-MIBC (T2-4aN0M0) between 1 January 2015 and 31 December 2021 who received either radical radiotherapy or radical cystectomy after NAC. The data will be linked to Hospital Episode Statistics (HES), National Radiotherapy Data Set (RTDS) and Systemic Anti-Cancer Therapy (SACT) data sets to gather information on clinical, tumour and socio-demographic characteristics and receipt of treatment. Using the target trial emulation framework, we will define the eligibility criteria and radical radiotherapy and radical cystectomy receipt. To reduce the risk of confounding, we will use advanced statistical approaches to allow for differences in measured baseline characteristics between the comparison groups.

The primary outcome is 3-year all-cause mortality after radical treatment receipt. Secondary outcomes will include all-cause and bladder-cancer-associated mortality at 3 and 5 years, time to death, incremental costs and incremental cost-effectiveness reported according to net health benefits.

Ethics and dissemination

The study was approved by the London School of Hygiene and Tropical Medicine Ethics Committee (Reference number 29717 - 1). Results will be communicated in open-access journals and conferences to clinicians, researchers, patients and policymakers.

Participants

334 people reported a new pregnancy within 1 year of enrolment; 324 with outcome data are included in this analysis.

Primary and secondary outcome measures

Types of pregnancy care sought (‘Have you looked into where or how you could get (prenatal care, abortion care or adoption services)?’) and care-seeking stress (‘How stressful was it to find (prenatal, abortion or adoption) care for this pregnancy?’).

Results

Most participants (83%, 270/324) sought prenatal care; 43% (138/324) sought abortion care; and 5% (17/324) sought adoption services. Overall, 17%, 29% and 23%, respectively, reported that care-seeking was extremely/quite a bit stressful. Abortion care-seeking was associated with significantly more stress than seeking prenatal care in the ordinal (adjusted odds ratio (aOR 1.70, 95% CI 1.10 to 2.62) but not logistic (aOR 1.33, 95% CI 0.74 to 2.38) model. Adoption care-seeking stress did not differ from prenatal care-seeking stress in either model. Participants who experienced any type of abortion care-seeking obstacle and those recruited in a state with a restrictive policy environment (aOR 2.72, 95% CI 1.09 to 6.80) reported more care-seeking stress than their counterparts.

Conclusions

People who seek pregnancy care often experience some care-seeking stress, regardless of the type of care they seek. Findings point to the need to reduce the burden of the pregnancy care-seeking process across all types of pregnancy care.

How do acute worsening events influence daily life and healthcare-seeking behaviour in patients with COPD: an international multicountry qualitative study

Por: Dijk · L. · Driessen · M. M. G. · Gerritsma · Y. H. · Bolton · C. · Da Silva · C. · Kocks · J. W. H.
Objective

To explore the impact of acute worsening events (AWEs), defined as clinically relevant deteriorations in peak expiratory flow, reliever use and/or symptoms, on patients’ daily lives and identify behaviours linked to their recognition and management.

Design

A qualitative international substudy was conducted in the Netherlands, Spain, the USA, Canada and the UK (2023–2024).

Participants

19 patients with moderate-to-severe chronic obstructive pulmonary disease (COPD) from a randomised clinical trial participated. Interviews, triggered by AWEs and repeated 6 weeks later, were audio-recorded, transcribed and analysed.

Results

Patients varied in identifying bad days, reporting inability to perform physical activities, symptom worsening or the need for add-on treatment. Recognition of AWEs depended on their duration: shorter events (

Conclusions

AWEs significantly impact daily life but vary widely in recognition and thresholds for seeking care. Limited awareness of daily disease variations may contribute to both under-reporting of worsening events to healthcare providers and suboptimal self-management in COPD.

Effects of Erbium:YAG laser combined with vaginal estriol therapy in postmenopausal women with Genitourinary Syndrome of Menopause: protocol for a randomised, double-blind, controlled trial

Introduction

Genitourinary syndrome of menopause (GSM) is a chronic, oestrogen-deficient condition that is frequently underdiagnosed and undertreated. Although low-dose vaginal estriol improves epithelial trophism and microbial balance, a substantial proportion of women report persistent symptoms. High-quality randomised evidence evaluating combined therapeutic strategies remains scarce. Energy-based modalities, including the erbium:YAG (Er:YAG) laser (=2940 nm), have been proposed as adjunctive treatments. This trial aims to assess the efficacy of Er:YAG laser therapy combined with vaginal estriol compared with estriol alone in postmenopausal women with GSM.

Methods and analysis

This is a single-centre, randomised, double-blind, controlled clinical trial. Postmenopausal women aged 45–70 years with vaginal pH ≥5.0 and at least one moderate GSM symptom (Visual Analogue Scale ≥4) will be eligible. Exclusion criteria include current systemic or local hormone therapy, previous vaginal energy-based treatment, abnormal cervical cytology and body mass index ≥35 kg/m2. All participants will receive vaginal estriol cream (0.5 mg per dose) daily for 14 days, followed by twice-weekly administration for 16 weeks. Participants will be randomised (1:1) to receive either estriol plus sham Er:YAG laser or estriol plus active Er:YAG laser. Three laser sessions will be delivered at approximately 4-week intervals. Assessments will occur at baseline, monthly during treatment and 4 months after the final session. The primary outcome is the Vulvovaginal Health Index, with the primary endpoint defined as the change from baseline to 4 months post-treatment, reflecting sustained effect. Secondary outcomes include GSM symptom severity, vaginal microbiome composition (16S rRNA sequencing), quality of life (Menopause Rating Scale) and sexual function (Female Sexual Function Index). Data will be analysed using repeated-measures analysis of variance or appropriate non-parametric tests, with significance set at p

Cost analysis of the use of digital rectoscopy versus flexible sigmoidoscopy in rectal cancer patients undergoing watch and wait

Por: Sekhon Inderjit Singh · H. K. · Harper · H. · Butnari · V. · Beni · R. · Lozano · E. · Goede · A.
Introduction and objective

Organ preservation strategies for rectal cancer following neoadjuvant treatment require intensive endoscopic monitoring to detect early luminal recurrence. This is termed 'Watch and Wait' (WAW). Standard protocols commonly mandate flexible sigmoidoscopy every 3–4 months for 2 years. Digital proctoscopy with the LumenEye device has been shown to be a safe alternative that can be performed in an outpatient setting without the need for sedation and with less staffing requirements. The study objective is to evaluate the economic implications of using digital proctoscopy compared with flexible sigmoidoscopy for patients with rectal cancer managed under a WAW protocol.

Setting and design

The study was conducted in a secondary care National Health Service (NHS) setting. A cost comparison analysis was performed over a 2 year time horizon (seven procedures per patient). 177 procedures on rectal cancer patients undergoing WAW with digital proctoscopy between August 2023 and November 2024 were included. The control group, that is, flexible sigmoidoscopy was modelled. The base case was flexible sigmoidoscopy without sedation. Scenarios using sedation were also evaluated. Costs were categorised into fixed and variable costs. A one-way sensitivity analysis, probabilistic sensitivity analysis and What-If scenarios were also performed.

Outcome measures and results

The primary outcome was the minimum cost difference between the two procedures. The secondary outcome measure was the robustness of the cost differences. Over 2 years, the total cost per patient was £768.92 (95% CI £656.6 to £900.7) for digital proctoscopy compared with £1,588.15 (95% CI £1458.1 to £1725.2) for flexible sigmoidoscopy without sedation. The absolute minimum cost saving per patient is £820.23 (95% CI £648.7 to £985.1). Cost savings increased to £848.94 (95% CI £677.20 to £1013.83) to £935.62 (95% CI £761.02 to £1103.08) when sedation was used in flexible sigmoidoscopy procedures. Personnel costs during the procedure and recovery phase were the dominant cost drivers for flexible sigmoidoscopy. Probabilistic sensitivity analysis and What-If scenarios confirmed the robustness of the findings, with flexible sigmoidoscopy remaining more costly.

Conclusion

Digital proctoscopy with the LumenEye device is a cost-saving alternative to flexible sigmoidoscopy for patients with rectal cancer on a WAW protocol. Our findings support the integration of digital proctoscopy into WAW pathways as a cost-efficient alternative within resource-constrained healthcare systems. Endoscopy service pressures are also likely to be alleviated.

The LIFE study: a cross-sectional study protocol for LIfestyle risk Factors for chronic disease across the stagEs of reproductive ageing

Introduction

The dynamic physiological and hormonal changes through the menopause transition predispose women to an increased risk of chronic diseases including cardiovascular disease, metabolic disease, depression and dementia. The underlying mechanisms remain unclear, yet it is thought that chronic systemic inflammation and changes to lifestyle behaviours play important roles. The LIfestyle risk Factors for chronic disease across the stagEs of reproductive ageing (LIFE study) is a cross-sectional study aimed to characterise how hormonal and lifestyle (physical activity, diet and sleep) differences across pre, peri and postmenopause influence chronic systemic inflammation, visceral adiposity, cognitive function and sleep health.

Methods and analysis

Women aged between 40 and 65 years were recruited and classified into pre, peri or postmenopausal groups. Body composition measures and blood samples were collected. Sleep and physical activity were objectively measured using activPAL4 and ActiGraph GT9X link accelerometer over 7 days. Participants were also provided with a sleep diary. Physical function was assessed using the Short Physical Performance Battery. Cognitive function was evaluated using Addenbrooke’s Cognitive Examination-III and Cambridge Neuropsychological Test Automated Battery. Participants completed a series of questionnaires: Depression, Anxiety and Stress Scale-21, RuSATED, Berlin Questionnaire, Insomnia Severity Index, Activities-specific Balance Confidence Scale and the Australian Eating Survey.

Ethics and dissemination

Ethical approval was received from the relevant University Human Research Ethics Committee (ethics approval number #S221718) prior to the commencement of the research project. Data collection is ongoing and expected to be completed by April 2026. Results are expected to be available from July 2026. Findings will be disseminated in national and international conferences and in peer-reviewed journals and expected to inform how differences in lifestyle behaviours across menopause influence chronic systemic inflammation, visceral adiposity and cognitive function. Understanding and characterising the links between lifestyle behaviours and menopausal symptoms will inform targeted strategies to improve long-term well-being, heart, brain and metabolic health.

Introduction

In current practice, fluid volumes administered to children following kidney transplant vary widely. Up to 52% of children experience fluid overload-related complications. Current fluid guidelines are not evidence-based and the optimal amount of fluid for children after transplant is not known. The aim of Randomised multiple centre trial of conservative versus LIberal fluid adMInisTration for children receiving a kidney tranSplant (LIMITS) is to determine whether relative limitation of fluid volume administered to children receiving kidney transplants is superior to liberal fluid volume administration.

Methods and analysis

LIMITS is a pragmatic, open-label, UK-based, multicentre randomised controlled trial, with an internal pilot phase and integrated economic evaluation. A total of 140 children receiving kidney transplants will be randomised to receive either conservative postoperative fluid administration (maximum of 150 mL/m2/hour for no longer than 18 hours, followed by a fixed daily target of maximum 1.5 L/m2/day thereafter) versus the comparator of liberal postoperative fluid administration (fluid volume administered to replace urine output and insensible losses for at least 48 hours with target urine output >2 mL/kg/hour). The primary outcome is mean days at home in the first 30 days after kidney transplant. The primary outcome will be analysed using a mixed linear regression model adjusted for donor type (living vs deceased donor) and participant weight (

Ethics and dissemination

The trial received Health Research Authority approval on 20 August 2025 (REC reference: 25/EE/0161, IRAS project ID: 354370). Findings will be presented to academic groups via national and international conferences and peer-reviewed journals. The patient and public involvement group will play an important part in disseminating the study findings to the public domain.
