Multidrug-resistant tuberculosis (MDR-TB) is an urgent public health challenge in Namibia, with profound socioeconomic consequences. The high burden of both tuberculosis and HIV complicates treatment and underscores the need for optimised drug therapies. Precision medicine, which leverages patient-specific genetic and molecular information, offers promise for improving MDR-TB outcomes. However, its effective application relies on population-specific data, particularly understanding how individuals metabolise tuberculosis drugs and how genetic diversity drives variability in treatment response. Currently, no pharmacokinetic (PK) or pharmacogenetic (PG) data on TB treatment exist for Namibian populations. This gap is particularly concerning, given the country’s genetic diversity, environmental factors and comorbidities that may uniquely influence drug metabolism. This study aims to generate PK and PG data to inform dose optimisation and support personalised treatment strategies for MDR-TB in Namibia. The findings will contribute to improved patient care and inform health system strengthening based on locally relevant evidence.
This cross-sectional study will consist of 100 Namibian participants with matched human DNA and PK data of MDR-TB cases receiving isoniazid, clofazimine, bedaquiline and the fluoroquinolones (levofloxacin or moxifloxacin). PK sampling will be divided as follows: 30 individuals will undergo intensive PK sampling, while the remaining (n=70) will undergo sparse PK sampling. DNA will be extracted at Stellenbosch University (SU), and samples will be genotyped using the H3Africa microarray. Sequences will be aligned to the human reference genome, hg38 (GRCh38p13), using the freely available Burrows-Wheeler Aligner. A subset of the samples (n=20–30) will undergo whole genome sequencing (WGS) to verify imputation results and identify novel genetic variants potentially affecting PK in this population.
Quality control and variant call format file generation will be performed using the Genome Analysis Toolkit best practices (V.3.5). Intensive and sparse PK data will be pooled for the development of a population PK (popPK) model using a non-linear mixed-effects modelling approach. The popPK model will characterise the relationship between TB drug dose and exposure, including quantifying covariates, including genetic variation, explaining PK variability, providing a foundation for dose optimisation and personalised treatment strategies.

To assess the acceptability and adoption of multiparameter point-of-care testing (POCT) devices for the diagnosis and management of non-communicable diseases (NCDs) at the primary healthcare level in a resource-limited region of Peru.
Qualitative case-control process evaluation.
Eight primary healthcare facilities in northern Peru, including both urban and rural centres, where routine chronic care and laboratory services are provided.
Sixty-three participants: 36 patients, 12 laboratory technicians, 10 healthcare professionals and five facility heads. Eligible patients were ≥18 years, residing in the catchment area, with or without prior NCD diagnoses. Healthcare workers, including physicians, nurses, laboratory staff and facility managers.
Multiparameter POCT devices were installed in four intervention facilities, accompanied by staff training and community awareness activities, while four control facilities continued with conventional laboratory diagnostics.
Primary outcome: perceptions of patients and healthcare workers regarding the acceptability and adoption of POCT devices. Secondary outcomes: identification of facilitators and barriers to implementation, including infrastructure, supply chains and training gaps.
(1) Individuals: POCT was valued for speed and comfort, but concerns over accuracy were mentioned. (2) Intervention characteristics: laboratory staff valued POCT’s practicality in emergencies, but noted limitations in handling multiple samples. (3) Outer setting: urban centres outperformed rural facilities, with more staff and longer operating hours. (4) Inner setting: calibration gaps impacted POCT and conventional test reliability, requiring quality control and training. (5) Process: clear staff communication boosted patient confidence in POCT, but inconsistent training could lead to reliability doubts.
Multiparameter POCT devices show promise for enhancing NCD care in resource-limited primary healthcare settings, particularly in rural areas. However, their sustainability depends on broader health system reforms, including reliable supply chains, expanded training and stronger quality assurance mechanisms. Further research should examine strategies for embedding POCT within national regulatory and policy frameworks.
We investigated symptoms reported before and after heart failure (HF) diagnosis and their associations with 3-month hospitalisation and mortality.
To examine associations between symptoms recorded in primary care and short-term hospitalisation and mortality in HF patients.
Landmark analysis using Royston-Parmar survival models at baseline (diagnosis), 6 and 12 months post-diagnosis.
Primary care database (Clinical Practice Research Datalink) linked to hospital and mortality data (1998–2020).
Adults (>40 years) with a first HF diagnosis.
Shortness of breath, ankle swelling, oedema, fatigue, chest pain, depression and anxiety in the 3 months before diagnosis and at 6 and 12 months.
3-month all-cause hospitalisation and mortality; secondary outcomes included HF and non-cardiovascular hospitalisation.
Among 86 882 HF patients (62 742 and 54 555 surviving to 6 and 12 months, respectively), the magnitude of symptom risk varied by timepoint. Specifically, the symptoms with the strongest associations with adverse outcomes were: depression for all-cause hospitalisation at diagnosis (HR: 1.26; 95% CI 1.15 to 1.39) and 6 months (1.46; 1.25 to 1.70); ankle swelling for mortality (1.49; 1.14 to 1.94) at 6 months and SOB for HF hospitalisation (1.18; 1.12 to 1.26) at diagnosis and 12 months (1.99; 1.68 to 2.35).
Symptoms persisted and were more prominent at 6 and 12 months post-diagnosis than at diagnosis.
To explore experiences of healthcare providers, stroke survivors and caregivers on stroke transitional care delivery at a tertiary hospital in Tanzania.
A qualitative descriptive design with a phenomenological approach was used. Colaizzi’s thematic analysis was conducted using Dedoose software to identify significant information that describes the transitional care experiences of the study participants.
This study was conducted in the internal medicine and outpatient departments of a tertiary hospital in Tanzania.
15 triads of healthcare providers, stroke survivors and caregivers were purposively recruited to participate in semi-structured in-depth interviews between June and September 2024.
The analysis identified four themes: communication and exchange of information, involvement of patients and caregivers in transitional care, coordination of transitional care and experiences with changing care setting. Effective communication and information exchange among healthcare providers, survivors and caregivers ensured that survivors and their caregivers were well informed about the care process, clinical condition, prognosis and transitional care needs. A collaborative care approach enabled survivors and caregivers to actively participate in care, decision-making and discharge planning during hospital-to-home transition. Coordination of care was equally important during hospital-to-home transition as it provided survivors with home-care instructions and opportunities for follow-up care. However, miscommunication among the healthcare team, insufficient information exchange, inadequate discharge planning, poor social support and lack of care coordination prevented smooth hospital-to-home transition leading to a crisis at home.
The experiences of healthcare providers, patients and caregivers during stroke transitional care in Tanzania highlight achievements and key areas for improvement. Hospital-to-home transition is often characterised by uncertainty and emotional strain, emphasising the need for effective communication, involving patients and caregivers in care, as well as coordinating transitional care to address medical and psychosocial needs of survivors and their caregivers during and after discharge.
The surge in postsecondary students reporting mental health concerns, coupled with increased utilisation of on-campus and hospital-based mental healthcare, highlights a need to understand effective service navigation. To address this system gap, the University of Toronto and the Centre for Addiction and Mental Health (CAMH) leveraged their unique expertise and resources to develop the University of Toronto Navigation (UTN) service. UTN introduces care navigators to facilitate postsecondary student transitions from acute mental health services to community or campus mental healthcare. There has been limited implementation and evaluation of navigator models specific to the postsecondary context to date, which hinders scalability. This paper describes the study protocol of Navigation to Enhance Post-Secondary Students’ Acute Mental Health Care Transitions, a study that aims to collaborate with students, navigators and clinicians to evaluate the UTN service.
A one-stage, single-arm multimethods study design will be used to evaluate the UTN service. We will recruit 103 students following their UTN intake appointment. Students will complete quantitative measures assessing health outcomes, experiences of care and service utilisation at baseline and at three subsequent time points across a 6-month follow-up period. The quantitative data will be linked to administrative healthcare data. The primary evaluation outcome will be defined as attending an appointment with an appropriate care provider (in person or virtually) within 30 days of discharge from the hospital. We will conduct interviews with students and referring clinicians to gather perspectives regarding their experiences and satisfaction with the UTN service in greater depth.
Research ethics board approvals have been obtained from the University of Toronto and CAMH. Results will be disseminated through publications and presentations, and a toolkit will be cocreated to support implementation and adaptation of hospital-based navigator interventions in postsecondary contexts.
To explore how people perceive different forms of education for rotator cuff-related shoulder pain in terms of words or feelings evoked by the education and treatments they feel are needed.
We performed a content analysis of qualitative data collected in a randomised experiment.
2237 participants with rotator cuff-related shoulder pain were randomly assigned to receive three forms of education: best practice education, best practice education plus pain science messages and structure-focused education.
After receiving the education, participants answered two questions regarding (1) words or feelings evoked by the education and (2) treatments they felt were needed.
2232 responses for each question were analysed (99.7% response rate). Participants who received best practice education more frequently expressed feelings of unhappiness/frustration. The addition of pain science messages to best practice education resulted in slightly more emotional responses and a greater sense of being validated or cared for. In contrast, participants who received structure-focused education more frequently expressed trust in the clinician’s expertise and the need for medication, activity modification, rest, diagnostic imaging, injections and surgery. These participants also less frequently considered exercise as a viable treatment option.
Participants with rotator cuff-related shoulder pain expressed generally similar emotional responses across groups, with small differences in treatment preferences favouring self-management in the best practice education groups compared with those who received structure-focused education. Those in the best practice education also less frequently reported needing potentially unnecessary treatments (eg, imaging, injections and surgery).

This study assessed the feasibility of implementing a phase 3 field-based clinical trial protocol to evaluate paediatric praziquantel (PED-PZQ) for the treatment of Schistosoma mansoni infection in children aged 3 months to 6 years in endemic areas of Brazil, focusing on operational aspects such as recruitment logistics, documentation management, investigational product handling and protocol adherence.
Pilot and feasibility study for a phase 3 clinical trial, comprising two components: a randomised, open-label, parallel-group, two-arm trial and a single-arm trial.
Conde, Bahia, Brazil, from December 2024 to January 2025.
Two trials aim to screen 5774 participants from three rural areas in Bahia and three in Sergipe, states in northeastern Brazil, and enrol 403 children eligible for either randomisation or allocation. Trial 1 will randomise (1:1 ratio) 240 children aged 4–6 years into the PED-PZQ treatment arm or the standard praziquantel (PZQ) 1. Trial 2 will enrol 163 children aged 3 months to 3 years, all receiving PED-PZQ. Both trials are open label. Eligible participants shall meet age criteria, test positive for S. mansoni and fulfil other inclusion criteria. In the first recruiting centre, Conde (Bahia), it was estimated that 650 participants would need to be screened for trial 1 and 552 for trial 2, assuming schistosomiasis prevalence of 5% and 4%, respectively. This pilot study reports on the first 60 participants enrolled.
The primary outcome of this pilot study is the feasibility of implementing the research protocol in a real-world field setting, focusing on key aspects such as study documentation challenges, participant safety, investigational medicinal product custody chain and protocol adherence. In addition to providing preliminary data on the parasitological cure rate, secondary outcomes include the prevalence of S. mansoni infection and the reduction in S. mansoni egg count (Kato-Katz method). Furthermore, the occurrence and severity of drug-related adverse events are monitored from drug administration to day 21 post-treatment, alongside changes in renal, hepatic and cardiac functions assessed through biochemical markers.
A total of 60 participants were recruited, and 55 provided stool samples for screening. The pilot phase demonstrated the feasibility of implementing the clinical protocol under field conditions, with successful completion of all planned procedures and minimal protocol deviations. Operational challenges were identified mainly in documentation processes, participant recruitment and investigational product management and were addressed through preventive and corrective quality assurance actions. The experience also highlighted logistical and infrastructural barriers typical of field-based trials in remote endemic areas, which informed adjustments for the subsequent phase 3 study. Preliminary parasitological results indicated an overall S. mansoni prevalence of 9.1% (5/55), with 21% in trial 1 and 2.8% in trial 2. All infected participants met the eligibility criteria, received treatment and completed follow-up. Four achieved a parasitological cure, and one case of treatment failure was observed (trial 1, PZQ group). Two mild adverse events (diarrhoea) were reported, with no serious complications or clinically significant changes in biochemical parameters.
This pilot study demonstrated the feasibility of implementing a field-based phase 3 clinical trial protocol for PED-PZQ in endemic areas of Brazil. The findings confirm that the protocol can be successfully applied in primary care settings, despite operational challenges related to recruitment, logistics and documentation. The study also provided preliminary evidence supporting the safety and effectiveness of the paediatric formulation and highlighted the need to revise prevalence assumptions to improve future screening strategies. Overall, the experience offers valuable insights to guide the large-scale phase 3 trial and supports the incorporation of PED-PZQ into national schistosomiasis control policies.

People with serious mental illness (SMI) can experience significant physical health challenges. The Health Champions intervention was developed to support their physical health through using trained volunteers. However, volunteer and patient perspectives on the impact and implementation of this intervention have yet to be understood.
To compare the views of patients and volunteers on the Health Champions intervention.
A qualitative thematic analysis was conducted on interviews with 29 study participants. Interviews were carried out either face-to-face, via Microsoft Teams, or by telephone and included 12 patients (6 men and 6 women) and 17 volunteers (the Health Champions) (5 men and 12 women).
Four overarching themes were identified, highlighting both similarities and differences between stakeholders’ perspectives: (1) supporting goal setting; (2) impact on positive lifestyle; (3) experiences and perception of the programme and (4) navigating challenges during the programme. Both groups found the programme to be largely successful, by motivating patients to work towards their physical health goals and facilitating successful matching of patients with volunteers. Volunteers and patients valued good communication with the research team. Though both groups shared some views on the challenges with scheduling and a lack of face-to-face contact during the COVID-19 pandemic, their perceptions on how patients incorporated their health changes during and after the programme, as well as other administrative concerns such as views on the efficacy of journaling and breakdown of roles, differed.
The Health Champions intervention was perceived as useful to improve the physical health of patients with SMI. Differences in the views between the two stakeholders may result from their distinct experiences and expectations. Future volunteering programmes should further support the diverse physical health needs of patients with SMI.
The literature examining direct-to-consumer (DTC) commercial virtual care has expanded rapidly over the past decade. Our objective was to synthesise the nature and range of evidence on DTC commercial virtual care.
Scoping review.
MEDLINE ALL, EMBASE Classic+Embase, CINAHL, HealthSTAR, PsycINFO, CENTRAL and grey literature sources.
We included original research studies published in English or French between 1 January 2016 and 30 April 2025 that assessed DTC commercial virtual care in all contexts and in all populations.
Screening titles and abstracts, and full-text manuscripts, and extracting data was done in duplicate. We analysed quantitative data using descriptive statistics and reported findings in tables. We provided a narrative summary of textual data.
After excluding duplicates, we identified 8055 studies for title and abstract screening; 691 articles for full-text screening; and 103 studies meeting our inclusion criteria. 32 studies (31.1%) reported financial ties to the virtual care industry. 67 (65.0%) studies were conducted in the USA. Studies were largely quantitative (87/103 (84.5%)) or mixed methods (8/103 (7.8%)) studies and used cross-sectional (85/95 (89.5%)) designs. Most quantitative studies were descriptive, reporting on quality of care, health outcomes, platform characteristics and patient views, with only 24 of the 95 quantitative studies (25.3%) including a control or comparison group. 18 of these 24 studies (75.0%) compared the quality of care, costs and/or utilisation to other models of care and reported variable findings. The rest compared patient characteristics. Few studies assessed clinician perspectives or addressed privacy-related ethical concerns.
Despite a large number of studies assessing DTC commercial virtual care, we have little insight into impacts on quality of care, health outcomes, health system utilisation and privacy-related ethical concerns. The financial ties with industry suggest that there may be bias in the body of research literature.
Psoriatic arthritis (PsA) is a form of inflammatory arthritis linked to psoriasis. Previous research from the UK has found that many people feel unsupported when diagnosed with PsA and lack confidence in managing their condition. This realist review aims to understand what works and does not work for whom and in what circumstances, in relation to healthcare professionals engaging with people to support them in developing self-management skills.
This protocol was developed by defining the scope of the review, using a brief directed literature review to support discussion by an expert group of researchers, healthcare professionals and a patient partner. A theoretical domains framework was generated, consisting of nine initial programme theories. These were further refined with input from Patient and Public Involvement and Engagement groups and used to develop a database search strategy.
A systematic search of MEDLINE, CINAHL, Embase, Emcare and APA PsycINFO will be carried out, supplemented by citation tracking, exploration of grey literature and a mixed methods survey of rheumatology health professionals. Data selection will be performed by a minimum of two reviewers and data from included sources will be extracted using a template. Data will be synthesised narratively with respect to the identified initial programme theories, using these data to refine or refute these theories. This will generate refined programme theories to explain what works for whom and in what circumstances.
Ethical approval for the health professionals survey was granted through the Research Ethics Committee, University of the West of England (Project ID: 10991848). Outputs will be disseminated to the research community through conference presentations and a peer-reviewed journal article. The strategy for sharing outputs with patients and health professionals will be discussed and agreed with knowledge user groups.
This scoping review protocol aims to examine the role of the Internal Regulation Core (IRC) as an intra-hospital governance structure that coordinates capacity and patient flow and may function as a strategic hub for disruptive innovation in hospital management. By integrating organisational routines, rules and, when available, enabling technologies, IRCs may strengthen operational efficiency and contribute to higher-quality care delivery. As hospitals face increasing operational complexity and constrained resources, clarifying what IRCs are, how they are implemented across settings, and what innovations and impacts are reported has become a priority.
This scoping review will follow the Joanna Briggs Institute guidance and Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. A comprehensive search will be conducted across five databases (MEDLINE/PubMed, Embase, Scopus, Web of Science and LILACS) and grey literature sources, without language or date restrictions. The searches were conducted up to 6 July 2025. Two reviewers will independently screen studies and extract data using a standardised form; disagreements will be resolved by consensus or a third reviewer. Findings will be synthesised descriptively and thematically, with results presented in tables and narrative summaries, including innovation streams.
Open Science Framework (10.17605/OSF.IO/HWZJS).
Despite evidence of the cost-effectiveness of physical activity (PA) promotion interventions in healthcare settings, translating them into practice remains challenging. This study aimed to identify implementation barriers and facilitators of a Portuguese PA consultation programme implemented in primary healthcare of the Portuguese National Health Service. Additionally, it sought to inform future implementation strategies, using a theoretically based approach.
Qualitative interview study, using both deductive and inductive approaches.
Primary healthcare units across all health administration regions of mainland Portugal.
Twenty-eight participants (six medical doctors, five exercise professionals and 17 patients) from all health regions of the country, involved in the implementation of the Portuguese PA prescription consultation.
Fifty-three categories of determinants were identified, using the Tailored Implementation for Chronic Diseases framework. Key barriers included ineffective referral processes to the consultation, challenges in integrating the intervention with existing healthcare demands and insufficient local/regional prioritisation of PA promotion. Key facilitators included high intervention acceptability, diverse community PA resources and good interpersonal skills of implementers. Drawing on the Behaviour Change Wheel, theoretically based inputs to design strategies addressing each barrier were provided.
The implementation of PA consultation was influenced by a broad range of determinants. The most frequently reported barriers are primarily structural and opportunity-related, suggesting system-level implementation strategies are most appropriate. Future strategies should consider implementing clinical standards/orientations for PA promotion, providing institutional incentives based on the attainment of PA indicators, expanding consultation coverage and diversifying referral strategies, reinforcing health system-community partnerships and strengthening training opportunities for implementers. These findings offer relevant insights for enhancing the future implementation of PA consultations, for scaling them up and, ultimately, to increase their effectiveness.
Visual Patient Predictive (VPP) is an AI-based extension of the Visual Patient Avatar (VPA) that integrates deep learning models to predict upcoming vital sign deviations and display them as dashed visual elements. By explicitly showing anticipated changes, the system aims to support level 3 situation awareness—the projection of future patient states. This multicentre simulation study will evaluate whether predictive algorithms and visualisations integrated into the VPA (resulting in VPP) improve clinicians’ ability to anticipate critical vital sign changes compared with conventional number-based and waveform-based monitoring and examine its effects on decision-making, confidence, workload and user acceptance.
This investigator-initiated, randomised, within-subjects crossover, computer-based simulation trial will be conducted at five academic centres in Switzerland, Germany and the United States. Medical professionals from anaesthesiology departments will complete scenario-based prediction tasks using both VPP (as the index test) and conventional monitoring (as the reference standard) in randomised order, with the same participant evaluating both modalities and the identical underlying clinical scenario used in each condition, following video-based training and a learnability test. The primary outcome is recall (true positive rate) of vital sign deviation predictions. Secondary outcomes include average lead time, precision, prediction confidence, number and correctness of proposed interventions, perceived workload (NASA-TLX) and qualitative usability feedback. Quantitative data will be analysed using a logistic generalised linear mixed model with random intercepts for centre and participant, and a random slope for the intervention effect. Qualitative interviews will undergo thematic analysis.
The leading ethics committee (Zurich, Switzerland; BASEC-Req-2023–00465) reviewed and approved the study protocol. Ethics committees at the other participating centres have obtained their respective approvals or waivers. Bonn: 2025–144-BO, Boston: 2025P000501, Heidelberg: S-376/2025, Munich: 2025–357 W-CB. As this simulation study involves only healthcare professionals performing prediction tasks based on simulated vital sign scenarios—without collection of patient data or any medically relevant personal data—it does not constitute human subjects research under applicable regulations. Study results will be disseminated through peer-reviewed publications and presentations at scientific conferences.
Evaluate tofacitinib efficacy, safety and persistence by sex in rheumatoid arthritis (RA).
Post hoc analyses using data from phase III placebo-controlled randomised controlled trials (ORAL Scan, ORAL Sync and ORAL Standard).
ORAL Scan, ORAL Sync and ORAL Standard were global, multicentre trials conducted across 111, 114 and 115 sites, respectively.
The trials enrolled adults with active RA and prior inadequate response to methotrexate (ORAL Scan/ORAL Standard) or ≥1 conventional synthetic or biologic disease-modifying antirheumatic drug (ORAL Sync). Post hoc analyses included 2265 patients (1870 female and 395 male).
Patients received tofacitinib 5 mg or 10 mg two times a day, adalimumab or placebo.
Efficacy outcomes to month 12 included American College of Rheumatology (ACR)20, 50 and 70 responses, Disease Activity Score in 28 joints (DAS28) (erythrocyte sedimentation rate (ESR))-defined low disease activity (LDA) and remission, DAS28 (C reactive protein (CRP)) ≤3.2 and
At baseline, female patients had similar DAS28(CRP and ESR), slightly higher HAQ-DI and lower FACIT-F scores versus male patients (n=395). ORs for active treatments (tofacitinib and adalimumab) versus placebo were generally >1 for ACR20, 50 and 70 responses, DAS28(CRP) ≤3.2 and
In post hoc analyses, tofacitinib was efficacious across both sexes, with higher responses in males observed particularly for more stringent composite endpoints and patient-reported outcomes. Findings are generally consistent with studies of other advanced RA therapies. Safety and persistence were similar across sexes. Interpretation is limited by the small proportion of male patients (

Total mesorectal excision (TME) is highly effective for early-stage rectal cancer, but is associated with considerable morbidity, which can substantially impair the quality of life (QoL) of patients. For very early tumours (low-risk cT1), local excision (LE) offers the possibility of organ preservation (OP) with reduced morbidity; however, its application is limited to a selected group. For early tumours where upfront LE is not feasible, primary OP with (chemo)radiotherapy as an alternative to TME surgery has been evaluated in the STARTREC phase II/III studies, which reported promising 1-year OP rates.
The STARTREC-3 trial aims to increase the 2-year OP rate from 60% to 80% in early rectal cancer (cT1–3abN0) and from 30% to 60% in early-intermediate rectal cancer (cT1–3abN1, ≤3 mesorectal nodes measuring ≤8 mm) by intensifying neoadjuvant treatment in different study arms.
STARTREC-3 is embedded in the STARTREC master trial protocol, which uses an adaptive platform study design allowing early termination of inferior treatment arms and the addition of novel arms. The multicentre STARTREC-3 trial investigates three parallel, non-comparative treatment strategies for patients with early and early-intermediate rectal adenocarcinoma who prefer OP over primary TME surgery. All arms start with 5x5 Gy radiotherapy, followed by: an endoluminal boost via contact X-ray brachytherapy (arm 1), an external beam radiotherapy (EBRT) boost by MR-guided EBRT (arm 2) or three cycles of capecitabine oxaliplatin systemic treatment chemotherapy (arm 3). Treatment allocation is predefined and centre-dependent. Response evaluations (MRI and endoscopy) are planned at 14–16 weeks and 26 weeks after onset of radiotherapy. The primary endpoint is the proportion of patients with successful OP at 24 months from onset of therapy. Secondary endpoints include toxicity, QoL, functional and oncological outcomes. Data will be analysed separately for early (cN0) and early-intermediate (cN1) disease. The total planned sample size is 210 patients across the three arms. Interim analyses will be performed for each study arm to determine early failures and discontinue ineffective arms.
The trial was approved by the medical ethics committee NedMec of the Netherlands and is registered in the EU Clinical Trials Information System (CTIS). The results will be published in an international peer-reviewed journal.

Pre-eclampsia and fetal growth restriction are leading causes of perinatal morbidity and mortality. A therapy that enhances maternal vascular function and promotes vasodilation to increase placental perfusion could treat both conditions.
Tissue kallikrein-1 is an endogenous enzyme that releases bradykinin to activate the bradykinin 2 receptor on endothelial cells. This induces potent vasodilation and pro-angiogenic, anti-oxidant and anti-inflammatory effects.
DM199 is a recombinant form of tissue kallikrein which can be administered intravenously or subcutaneously. Clinical trials in non-pregnant populations have demonstrated its safety. Being a protein, it is unlikely to cross the placenta. This protocol describes an early-phase trial for DM199 for pre-eclampsia and fetal growth restriction.
This phase IB/IIA open-label trial at Tygerberg Hospital, Western Cape Province, South Africa, will determine the safety and effective dose of DM199 for pre-eclampsia and/or fetal growth restriction. The trial consists of two parts. Part 1 will be an ascending dose finding study, treating women with pre-eclampsia and severe hypertension who are for planned birth within 72 hours. This will search for doses that safely lower blood pressure (n=3/dose, recruiting up to 42 participants). Part 2 is a safety and efficacy study of three cohorts of pregnant women (n=30/cohort): (1) with pre-eclampsia and severe hypertension requiring delivery within 72 hours, (2) with preterm pre-eclampsia (
The trial has ethical approval (Health Research Ethics Committee, Stellenbosch University, Protocol number M24/04/009) and is registered (Pan African Clinical Trial Registry, PACTR202404895013782) and approved by the South African Health Products Regulatory Authority (20240801). Data will be presented at international conferences and published in peer-reviewed journals.
Asthma is a chronic respiratory disorder requiring ongoing medical management. This ecological study investigated the spatial and temporal patterns of notification rates for asthma from clinic visits and hospital discharges and identified demographic, meteorological and environmental factors that drive asthma in Bhutan.
Monthly numbers of asthma notifications from 2016 to 2022 were obtained from the Bhutan Ministry of Health. Climatic variables (rainfall, relative humidity, minimum and maximum temperature) were obtained from the National Centre for Hydrology and Meteorology, Bhutan. The Normalised Difference Vegetation Index (NDVI) and surface particulate matter (PM2.5) were extracted from open sources. A multivariable zero-inflated Poisson regression (ZIP) model was developed in a Bayesian framework to quantify the relationship between risk of asthma and sociodemographic and environmental correlates, while also identifying the underlying spatial structure of the data.
There were 12 696 asthma notifications, with an annual average prevalence of 244/100 000 population between 2016 and 2022. In ZIP analysis, asthma notifications were 3.4 times (relative risk (RR)=3.39; 95% credible interval (CrI) 3.047 to 3.773) more likely in individuals aged >14 years than those aged ≤14 years, and 43% (RR=1.43; 95% CrI 36.5% to 49.2%) more likely for females than males. Asthma notification increased by 0.8% (RR=1.008, 95% CrI 0.2% to 1.5%) for every 10 cm increase in rainfall, and 1.7% (RR=1.017; 95% CrI 1.2% to 2.3%) for a 1°C increase in maximum temperature. An increase in one unit of NDVI and 10 µg/m3 PM2.5 was associated with 27.3% (RR=1.273; 95% CrI 8.7% to 49.2%), and 2.0% (RR=1.02; 95% CrI 1.0% to 4.0%) increase in asthma notification, respectively. The high-risk spatial clusters were identified in the south and southeastern regions of Bhutan, after accounting for covariates.
Environmental risk factors and spatial clusters of asthma notifications were identified. Identification of spatial clusters and environmental risk factors can help develop targeted interventions that maximise impact of limited public health resources for controlling asthma in Bhutan.
To examine how clinicians’ scepticism regarding patients’ self-reports of subjective symptoms can be internalised, leading to psychosocial and medical harms.
In-depth, semi-structured qualitative interviews with the resulting data analysed using reflexive thematic analysis.
43 individuals with Ehlers-Danlos syndrome (EDS) from Europe and North America completed a pre-survey, and 39 of those participants completed interviews for this study. Purposive sampling was used to obtain approximately equal numbers of participants with hypermobile EDS and the molecularly defined types of EDS.
Patients with both hypermobile and molecularly defined types of EDS reported high levels of self-doubt, with 73% of survey respondents questioning the extent—and even reality—of their private experiences of pain. Participants attributed much of their self-doubt to repeated dismissal and minimisation of their symptoms in healthcare settings, especially during childhood. Ultimately, self-doubt transformed not merely how they communicated their symptoms but also how they recognised, evaluated and even experienced them at a phenomenological level. While some participants developed coping strategies, others withdrew from the conventional medical system altogether.
These findings have important implications for clinicians, who may inadvertently reinforce self-doubt through discussion of diagnostic uncertainty. Doubt need not be delegitamising. Recognising and mitigating these potential harms requires epistemic humility and attention to the psychosocial dynamics of patient-provider interaction.
The use of data science for health research produces complex ethical, legal and social challenges that traditional ethical oversight mechanisms struggle to address. In Nigeria, the current ethical guidelines were not designed for these challenges which include pervasive data environments, consent for secondary data use, algorithmic decision-making and bias, privacy risks, involvement of commercial entities, data colonisation, inequitable benefit-sharing and commercial data holdings. To address these gaps, we developed a draft guideline incorporating principles like trust, veracity, global justice and alternative ethical approval mechanisms. Here, we describe the protocol for a study aimed at validating the guideline through stakeholder consensus on the content, feasibility and acceptability of this subcode for national implementation.
We describe the use of a modified e-Delphi approach to iteratively synthesize expert opinions about ethical oversight for data science health research (DSHR) led by a multidisciplinary working group from the Bridging Gaps in the ELSI of Data Science Health Research in Nigeria (BridgELSI) team. We will invite 65 experts, including health researchers, ethics committee members, data scientists, health policymakers, funders and key opinion leaders in Nigeria to participate. Participants will rate 13 core principles, including global justice, algorithmic bias, data governance and related governance provisions on importance, desirability for inclusion in national guidelines, feasibility and confidence in implementation, using 5-point Likert scales, with optional free-text comments. We will summarise responses using descriptive statistics, assess consensus and polarity using pre-specified thresholds for the mean and IQR, and iteratively refine statements between rounds using qualitative content analysis of comments.
Ethical approval was obtained from the Nigerian National Health Research Ethics Committee and the University of Maryland IRB, and participants will provide informed consent. Results will be shared with the expert panel and national regulators and disseminated via publications and conferences.
A successful extubation process is critical for the future health outcomes of paediatric patients, as it tests the functioning of the respiratory system without the support of mechanical ventilation. However, extubation can cause stress, pain, anxiety or discomfort in patients, which may sometimes lead to an increased likelihood of reintubation. Music-based interventions and therapies have been shown to be effective in reducing anxiety and stress levels in ventilated patients in the paediatric intensive care unit (PICU), but studies evaluating the effect of music therapy during the extubation process in the PICU are scarce.
This is a pragmatic multicentre randomised clinical trial with two parallel arms. The intervention group will receive standard care + music therapy during the extubation process, and the control group will receive standard care alone. The main outcome measure is heart rate, which will be measured every minute for 5 min pre-extubation, during the extubation process and up to 10 min postextubation. Secondary outcome measures are: oxygen saturation, respiratory rate, blood pressure and heart rate variability. A total of 82 patients will be randomised.
This study was approved by the Research Ethics Committee of the Fundación Universitaria Sanitas (CEIFUS 1356-24, date of approval: 3 May 2024). All parents or legal guardians of patients will sign a written informed consent, and if applicable, assent from participants will be sought. The results will be disseminated through publications in peer-reviewed journals, conferences and presentations at the hospitals’ clinical committees.
