Introduction

Transvaginal and transabdominal cerclage procedures have become established interventions to prevent mid-trimester pregnancy loss and preterm birth. Transabdominal cerclage seems to be superior to transvaginal cerclage in women with a history of a failed transvaginal cerclage. However, with the availability of a less invasive laparoscopic procedure, there is limited evidence concerning which type of cerclage to recommend to many other risk groups. The objective of this trial is to compare laparoscopic abdominal cerclage and transvaginal cerclage in women at moderate to high risk of spontaneous preterm birth.

Methods and analysis

The trial is an open, multicentre, superiority, parallel arm randomised controlled investigator-initiated trial with an embedded internal pilot. Women in whom the clinician has clinical equipoise between laparoscopic and transvaginal cerclage are randomised to either laparoscopic abdominal or transvaginal cerclage in a ratio of 1:1. The trial extends from sites in Denmark, Finland and Norway. The primary outcome is birth

Ethics and dissemination

The Central Denmark Region Committee on Biomedical Research Ethics, Denmark, Helsinki University Hospital Ethics committee, Finland and the Regional Committees for Medical and Health Research Ethics, Norway approved the trial. This protocol is published prior to complete data collection and analysis. Important protocol changes will be made publicly available on ClinicalTrials.org, on the trial website and distributed electronically to all active sites. Positive, inconclusive as well as negative results from the trial will be published in peer-reviewed international scientific journals.

Importance

Little research has been done on post-COVID symptoms at 24 months postinfection and on the association these may have on health-related quality of life (HRQOL).

Objective

We assessed the prevalence and severity of post-COVID symptoms and quantified EuroQol 5 Dimension 5 Level (EQ-5D-5L), self-perceived health question (EuroQol Visual Analogue Scale (EQ-VAS)) and health utility scores (HUS) up to 24 months follow-up.

Design

The longitudinal multiple cohort CORona Follow-Up (CORFU) study combines seven COVID-19 patient cohorts and a survey among the general public. The participants received questionnaires on several time points. Participants were stratified by: without a known SARS-CoV-2 infection (control group), proven SARS-CoV-2 infection but non-hospitalised, proven SARS-CoV-2 infection hospitalised to the ward, and proven SARS-CoV-2 infection hospitalised to the intensive care unit (ICU).

Setting

In this study, data of seven COVID-19 patient cohorts and a survey among the general public are included.

Participants

Former COVID-19 patients and controls participated in this cohort study.

Main outcomes and measures

Former COVID-19 patients and non-COVID-19 controls were sent questionnaires on symptoms associated with post-COVID condition. The CORFU questionnaire included 14 symptom questions on post-COVID condition using a five-level Likert-scale format. Furthermore, HRQOL was quantified using the EuroQol EQ-5D-5L questionnaire: EQ-VAS and the EQ-5D-5L utility score. The EQ-5D-5L questionnaire includes five domains that are scored on a five-point Likert scale: mobility, self-care, usual activities, pain/discomfort and anxiety/depression.

Results

A total of 901 participants (and 434 controls) responded at 24 months follow-up. In all former COVID-19 patients, the presence of post-COVID condition at 24 months was observed in 62 (42.5%, 95% CI 34.3% to 50.9%) of the non-hospitalised patients, 333 (65.0%, 95% CI 60.7% to 69.2%) of the hospitalised ward patients and 156 (63.2%, 95% CI 56.8% to 69.2%) of the ICU patients, respectively (p

Conclusions

Many former COVID-19 patients experience post-COVID symptoms at 24 months follow-up, with the highest prevalence in hospitalised participants. Also, former patients reported a lower HRQOL.

Trial registration number

The CORFU study was registered at clinicaltrials.gov (registration number NCT05240742).

Objectives

Although flow cytometric analysis of peripheral blood neutrophil myeloperoxidase expression can accurately rule out myelodysplastic neoplasms (MDS), it lacks reliability and efficiency due to the practical limitations of laboratory-developed liquid reagent-based assays. This study aimed to quantify the agreement and comparative discriminatory accuracy between a single-use flow cytometric lyophilised reagent tube (BD Lyotube Stain 468) and its laboratory-developed liquid reagent counterpart.

Design

Cross-sectional diagnostic accuracy study of two index tests against a reference diagnosis.

Setting

A university hospital in France.

Participants

Consecutive adult patients with an indication for bone marrow aspiration due to suspected MDS and unexplained peripheral blood cytopenia.

Primary outcome

MDS confirmed by cytomorphological evaluation of the bone marrow aspirate performed in duplicate by experienced haematopathologists blinded to the index test.

Results

Of 103 participants enrolled between July 2020 and August 2021, 37 had MDS (prevalence, 36%). The median intra-individual robust coefficient of variation (RCV) for myeloperoxidase expression was 30.9% using the BD Lyotube Stain 468 and 31.2% using the laboratory-developed liquid reagent assay, with an intraclass correlation coefficient of 0.94 (95% CI 0.91 to 0.96). The areas under the receiver operating characteristic curves were 0.83 (95% CI 0.74 to 0.90) and 0.82 (95% CI 0.73 to 0.89), respectively. Using a prespecified threshold of 30.0%, the corresponding sensitivity estimates were 89% (95% CI 75% to 97%) and 95% (95% CI 82% to 99%).

Conclusion

BD Lyotube Stain 468 performs as well as its laboratory-developed liquid reagent counterpart for the quantification of myeloperoxidase expression by peripheral blood neutrophils. It may obviate the need for invasive bone marrow aspiration in up to 40% of patients with suspected MDS.

Introduction

Tuberculosis (TB) remains a significant public health challenge in many African communities, where underreporting and underdiagnosis are prevalent due to barriers in accessing care and inadequate diagnostic tools. This is particularly concerning in hard-to-reach areas with a high burden of TB/HIV co-infection, where missed or delayed diagnoses exacerbate disease transmission, increase mortality and lead to severe economic and health consequences. To address these challenges, it is crucial to evaluate innovative, cost-effective, community-based screening strategies that can improve early detection and linkage to care.

Methods and analysis

We conduct a prospective, community-based, diagnostic, pragmatic trial in communities of the Butha Buthe District in Lesotho and the Greater Edendale area of Msunduzi Municipality, KwaZulu-Natal in South Africa to compare two strategies for population-based TB screening: computer-aided detection (CAD) technology alone (CAD4TBv7 approach) versus CAD combined with point-of-care C reactive protein (CRP) testing (CAD4TBv7-CRP approach). Following a chest X-ray, CAD produces an abnormality score, which indicates the likelihood of TB. Score thresholds informing the screening logic for both approaches were determined based on the WHO’s target product profile for a TB screening test. CAD scores above a threshold prespecified for the CAD4TBv7 approach indicate confirmatory testing for TB (Xpert MTB/RIF Ultra). For the CAD4TBv7-CRP approach, a CAD score within a predefined window requires the conduct of the second screening test, CRP, while a score above the respective upper threshold is followed by Xpert MTB/RIF Ultra. A CRP result above the selected cut-off also requires a confirmatory TB test. Participants with CAD scores below the (lower) threshold and those with CRP levels below the cut-off are considered screen-negative. The trial aims to compare the yield of detected TB cases and cost-effectiveness between two screening approaches by applying a paired screen-positive design. 20 000 adult participants will be enrolled and will receive a posterior anterior digital chest X-ray which is analysed by CAD software.

Ethics and dissemination

The protocol was approved by National Health Research Ethics Committee in Lesotho (NH-REC, ID52-2022), the Human Sciences Research Council Research Ethics Committee (HSRC REC, REC 2/23/09/20) and the Provincial Health Research Committee of the Department of Health of KwaZulu-Natal (KZ_202209_022) in South Africa and from the Swiss Ethics Committee Northwest and Central Switzerland (EKNZ, AO_2022–00044).

Introduction

Patients with stage III non-small cell lung cancer (NSCLC) are at high risk of developing post-treatment recurrences (50–78%) during follow-up. As more effective treatments are now available, especially for patients with oligometastatic disease, earlier detection of recurrences may prolong survival and health-related quality of life (HRQOL). With the use of 2'-deoxy-2'-[18F]fluoroglucose positron emission tomography/CT ([18F]FDG PET/CT) during follow-up, recurrences may be detected earlier. Therefore, the primary objective of this study is to compare the 3-year overall survival of patients with stage III NSCLC during follow-up surveillance with [18F]FDG PET/CT versus follow-up with conventional CT (usual care). Secondary objectives address the number, location and timing of recurrences, as well as HRQOL, cost-effectiveness and patient experiences of PET/CT scans.

Methods and analysis

In this multicentre randomised controlled clinical trial, 690 patients with stage III NSCLC (8th edition International Association for the Study of Lung Cancer (IASLC) Tumor, Nodes, Metastasis (TNM) classification) who completed curative intended treatment and started follow-up care (which may include adjuvant therapy) will be randomised 1:1 to either the intervention ([18F]FDG PET/CT) or the control group (CT). Patients will undergo follow-up scans during visits at 6, 12, 18, 24 and 36 months. Data will be collected using validated questionnaires, electronic case report forms and data extractions from the electronic health records. Additionally, blood samples will be collected, and interviews will be conducted.

Ethics and dissemination

The study protocol has been approved by the Medical Ethical Committee of the Radboudumc and review boards of all participating centres. Written informed consent will be obtained from all participants. Study results will be published in international peer-reviewed scientific journals and presented at relevant scientific conferences. Data will be published in a data repository or other online data archive.

Introduction

Alliance ruptures constitute a high risk of premature treatment termination and poor psychotherapy outcome. The Alliance-Focused Training (AFT) is a promising transtheoretical approach to enhance therapists’ skills in dealing with alliance ruptures.

Methods and analysis

To evaluate the effectiveness of Modified AFT with doubling (MAFT-D), a randomised, patient and evaluator-blinded, multicentre trial was designed comparing MAFT-D (delivered to trainee therapists and supervisors) and psychotherapy training/treatment as usual (TAU) for therapists (n=120) and their patients with depressive disorders (n=240). A total of 17 cooperating centres, each offering either cognitive-behavioural or psychodynamic psychotherapy training, will contribute to recruitment. Stratification by centre (both for therapists and patients) and hence therapeutic approach (cognitive-behavioural vs psychodynamic psychotherapies), and by comorbid personality disorder (yes vs no, for patients) will be carried out. The two hierarchically ordered primary hypotheses are: In MAFT-D compared with TAU, a stronger reduction of depressive symptoms and a lower rate of patient dropout is expected from baseline to 20 weeks after baseline. Follow-up assessments are planned at 35 weeks, 20 months and 36 months postbaseline to evaluate the persistence of effects. Secondary patient-related and therapist-related outcomes as well as predictors, moderators and mediators of change will be investigated. Mixed models with repeated measures will be used for the primary analyses.

Ethics and dissemination

Ethical approvals were obtained by the institutional ethics review board of the main study centre as well as by review boards in each federal state where one or more cooperating centres are located (secondary votes). Following the Consolidated Standards of Reporting Trials statement for non-pharmacological trials, results will be reported in peer-reviewed scientific journals and disseminated to patient organisations and media.

Objective

To develop models to predict opportunities for improvement in trauma care and compare the performance of these models to the currently used audit filters.

Design

Retrospective registry-based study.

Setting

Single-centre, Scandinavian level one equivalent trauma centre.

Participants

8220 adult trauma patients screened for opportunities for improvement between 2013 and 2022.

Primary and secondary outcome measures

Two machine learning models (logistic regression and XGBoost) and the currently used audit filters were compared. Internal validation by an expanding window approach with annual updates was used for model evaluation. Performance measured by discrimination, calibration, sensitivity and false positive rate of opportunities for improvement prediction.

Results

A total of 8220 patients, with a mean age of 45 years, were analysed; 69% were men with a mean injury severity score of 12. Opportunities for improvement were identified in 496 (6%) patients. Both the logistic regression and XGBoost models were well-calibrated, with intercalibration indices of 0.02 and 0.02, respectively. The models demonstrated higher areas under the receiver operating characteristic curve (AUCs) (logistic regression: 0.71; XGBoost: 0.74). The XGBoost model had a lower false positive rate at a similar sensitivity (false positive rate: 0.63). The audit filters had an AUC of 0.62 and a false positive rate of 0.67.

Conclusions

The logistic regression and XGBoost models outperformed audit filters in predicting opportunities for improvement among adult trauma patients and can potentially be used to improve systems for selecting patients for trauma peer review.

Objectives

Our study was designed to assess whether paired normal-tumour testing increased access to targeted therapy, clinical trials and influenced cancer screening recommendations given to patients and their families.

Design

Prospective cohort study.

Setting

Academic cancer centre in the Pacific Northwest region of the USA.

Participants

Patients newly diagnosed between 01 January 2021 and 31 December 2022 with cancers of the oesophagus, gastro-oesophageal junction and stomach (CEGEJS) were included. All other cancer diagnoses such as head and neck, duodenal and lower gastrointestinal tract cancers were excluded.

Intervention

Paired germline and tumour genetic test within 90 days of new patient visit.

Primary outcome measures

Number of targeted therapies received (or not) when eligible, follow-up treatment data and number of inherited predispositions to cancers identified. No secondary outcome measures.

Results

Of 42 patients, 32 (76.2%) were eligible for at least one targeted therapy. 19 patients received immunotherapy, when 16 had a biomarker predicting immunotherapy benefit, and benefit of immunotherapy was unclear for 3. Another 11 did not have this biomarker, and 6 of them received immunotherapy. Six pathogenic variants were identified in four high-risk genes. By 01 January 2024, 18 patients (42.9%) had died of complications of cancer.

Conclusion

More than 75% of patients who received tumour testing were eligible for a targeted therapy regardless of their stage at diagnosis, emphasising the need to expand access to testing with staging workup to improve survival outcomes. Six families received personalised screening recommendations, thanks to this study.

Understanding the relationship between adolescents with tuberculosis and health services: an indepth qualitative study from Cape Town

Por: Wademan · D. T. · Hoddinott · G. · Kavalieratos · Z. · Mlomzale · M. · Marthinus · A. J. · Jola · L. N. · Jacobs · S. · Mcimeli · K. · Seddon · J. — Mayo 25th 2025 at 02:10
Introduction

Adolescents’ experiences (10–19 years-old) with tuberculosis (TB) remain poorly understood. Descriptions of adolescent TB experiences, particularly how they interact with the health system, are scarce. We aimed to understand adolescents’ experiences of TB health services in the Western Cape, South Africa. We focused on how TB services were aided or hindered through interactions with healthcare providers and health system processes.

Methods

Teen TB, an observational study in Cape Town, enrolled 50 newly diagnosed adolescents with multidrug-resistant and drug-susceptible TB. A subset of 20 was selected for serial qualitative data collection, with 19 completing all tasks between December 2020 and September 2021. 52 interviews were conducted and thematically analysed using a case descriptive process for experiences across the TB care cascade.

Findings

Adolescents criticised the difficulties and delays they encountered in obtaining an accurate TB diagnosis. Initial misdiagnoses and delayed TB diagnoses were reported, despite seeking help from multiple healthcare providers at different facilities. Adolescents questioned whether the financial, social and emotional costs of TB care outweighed the costs of delaying treatment initiation and adherence. Adolescents reported that the treatment regimen, adherence support processes and interactions with the health system posed significant challenges to maintaining adherence. Encouragingly, however, most adolescents reported being well treated and cared for by health workers.

Conclusion

Our study shows that adolescents experience challenges throughout their TB treatment journeys. More adolescent-focused research is needed to tailor treatment and healthcare processes to their needs.

Objective

To evaluate the burden of asthma in five European countries (5EU; France, Germany, Italy, Spain and United Kingdom [UK]).

Design

A retrospective cross-sectional study was conducted based on the data from the 2018 National Health and Wellness Survey. Health-related quality of life (HRQoL), work productivity and activity impairment, and healthcare resource utilisation (HCRU) were compared between different groups: asthma versus non-asthma, mild/moderate/severe asthma versus non-asthma and moderate/severe asthma versus mild asthma.

Settings

Internet-based survey across Western Europe.

Participants

Adult patients (aged ≥18 years) with self-reported physician diagnosis of asthma and experienced asthma symptoms in the past 12 months.

Outcome measures

Socio-demographic characteristics, asthma-related outcomes, HRQoL and productivity, HCRU and prevalence of asthma.

Results

The prevalence of asthma in the 5EU was 6.7% (95% CI: 6.5% to 6.9%), with the UK reporting the highest rates (10.4%; 95% CI: 9.9% to 10.9%). About 52.0% of the respondents had mild asthma, 27.9% had moderate and 20.1% had severe asthma. The asthma group reported significantly poorer HRQoL, higher rates of overall work productivity impairment and activity impairment, and a greater number of visits to emergency room, healthcare provider and hospitalisations versus the non-asthma group (all p

Conclusion

Asthma prevalence and burden are still high in Western Europe, indicating the need for effective interventions that could lead to improved outcomes.

Objectives

The ‘Developing and evaluating an adapted behavioural activation intervention for depression and diabetes in South Asia (DiaDeM)’ trial investigates a psychological intervention, behavioural activation (BA), on people with both diabetes and depression in Bangladesh and Pakistan. This study aimed to aid the intervention and trial design.

Design

This was a modelling study using microsimulation to assess the intervention’s cost-effectiveness. Diabetes was modelled using the UK Prospective Diabetes Study model based on Pakistani patients and depression was modelled using Patient Health Questionnaire-9 (PHQ-9) trajectories allowing for multiple depressive episodes. It was assumed that diabetes-related adverse events increased depression recurrence, while depression impacted haemoglobin A1c, increasing diabetes-related events. The model estimated (1) maximum cost of BA which would be cost-effective (headroom analysis) to inform intervention design, and (2) value of reducing uncertainty around different measures (value of information analysis) to prioritise data collection in the DiaDeM study.

Setting

Analysis was conducted from a Pakistani healthcare perspective over a lifetime with costs and outcomes discounted at 3%.

Interventions

BA plus usual care was compared against usual care. BA involved six sessions by a trained (non-mental health) facilitator. The usual care comparator was the prevailing mix of pharmacological and non-pharmacological treatments used in Pakistan.

Primary and secondary outcome measures

The primary outcome was disability-adjusted life-years (DALYs). Secondary outcomes included life years, healthcare costs and the rate of depression and diabetes-related events.

Results

Over their lifetime, individuals receiving BA plus usual care avoid 3.2 (95% credible interval: 2.7 to 3.8) years of mild depression and experience fewer diabetes-related events. BA plus usual care resulted in an additional 0.27 (0.03 to 0.52) life years, 0.98 (0.45 to 1.86) DALYs averted and had incremental healthcare costs of –US$97 (–US$517 to US$142), excluding BA costs. The maximum cost per BA course at which was cost-effective is US$83 (US$9 to US$214). Value of information analysis found the most important measures to include in the trial are the impact of depression on diabetes and PHQ-9 over time.

Conclusions

This is the first model to jointly model depression and diabetes for South Asia and uses novel methods to reflect the diseases and inform intervention and trial design. This evidence has helped to inform the design of the DiaDeM intervention and the trial to evaluate it.

Randomised controlled trial of a psychosocial digital health application to promote coping for caregivers of patients undergoing haematopoietic stem cell transplantation: a study protocol for the BMT-CARE app

Por: Willis · K. D. · Barata · A. · Freese · M. · Applebaum · A. J. · Nelson · A. · Traeger · L. N. · Horick · N. K. · Rabideau · D. J. · Temel · J. S. · Greer · J. A. · Jacobs · J. M. · El-Jawahri · A. — Abril 9th 2025 at 06:01
Introduction

Caregivers of patients undergoing haematopoietic stem cell transplantation (HSCT) experience tremendous psychological distress before, during and after HSCT. However, few interventions are tailored to the protracted needs of these caregivers while considering scalability and accessibility. We previously developed an evidence-based intervention for caregivers of patients undergoing HSCT that improved quality of life (QOL), caregiving burden and mood. We have since adapted this clinician-delivered intervention into a self-administered, digital health application (BMT-CARE app) and are currently evaluating the effect of this intervention on QOL in caregivers of patients receiving HSCT.

Methods and analysis

The study design is a non-blinded randomised controlled trial of a digital health intervention for caregivers of patients undergoing HSCT at the Massachusetts General Hospital Cancer Center. We are enrolling and randomising 125 caregivers to receive the BMT-CARE app or usual care in a 1:1 assignment, stratifying by transplant type (autologous vs allogeneic). Caregivers assigned to the BMT-CARE app complete five self-guided modules designed to improve coping and stress management prior to and up to 60 days post-HSCT. The modules include interactive, gamified features and video vignettes to optimise engagement. Participants complete questionnaires at baseline and days 10, 60 and 100 post-HSCT. The primary outcome is comparison of QOL at day 60 post-HSCT. Secondary outcomes include caregiver burden, anxiety and depression symptoms, as well as post-traumatic stress symptoms. We are also exploring the usability of the BMT-CARE app to inform refinements prior to future testing.

Ethics and dissemination

The study is funded by the Leukemia and Lymphoma Society and approved by the Dana-Farber/Harvard Cancer Center Institutional Review Board (Protocol #22–634 v.1.5). The results of this study will be reported in accordance with the Consolidated Standards of Reporting Trials statement for non-pharmacological trials. Results will be disseminated at scientific meetings and in peer-reviewed journals.
