Impact of a patient-centred levothyroxine decision support tool on rapid achievement of target dosage and improved patient outcomes: protocol for a randomised controlled trial

Por: Konst · S. R. · Hellemo · L. · Garcia · B. H. · Brun · V. H.
Introduction

The hormone replacement drug levothyroxine is the most common therapy for people with reduced function of the thyroid gland. The optimal dosage varies considerably between individuals, and reaching the correct dosage is often a time-consuming task. To reduce the time needed for dose adjustments, we have developed a model for calculating each patient’s optimal dosage and an associated decision support tool (DST). We present the study protocol for a randomised controlled trial using the DST in initiation and adjustment of levothyroxine therapy for thyroidectomised patients. The aim of the study is to assess the tool’s efficacy on therapeutic target achievement and to investigate whether faster dose adjustments lead to better patient-reported outcomes on symptoms and health-related quality of life (HRQoL).

Methods and analysis

We will conduct a randomised, controlled, multicentre, non-blinded, parallel arm trial with three intervention groups and one control group. We will include 240 patients undergoing total or completion thyroidectomy in three Norwegian hospitals. Patients allocated to the three intervention groups will have the option to use the DST in dose adjustments after the operation. Each intervention group will test a different version of the DST. The control group will follow standard care practice. The randomisation ratio will be 1:1:1:1. Our primary outcome is proportion of patients within biochemical target at 8 weeks postoperatively. Secondary outcomes are distance from biochemical target at 8 weeks, mean time to achieve biochemical target, change in HRQoL, adverse events and number of days absence from work.

Ethics and dissemination

The study has been approved by the Norwegian Medical Products Agency (CIV-23-02-042436), The Norwegian Ethics Committee for Clinical Trials on Medicinal Products and Medical Devices (547311), and the patient protection officer at the University Hospital of North Norway. All participants will give written informed consent prior to inclusion. Results will be published open access in international peer-reviewed journals and communicated to the public through appropriate channels.

Por: Feder · S. C. · Simsek · Z. · Simon · J. J. · Hartmann · M. · Bruns · B. · Bugaj · T. J. · Hoch · J. · Dugas · M. · Friederich · H.-C.
Background

The length of hospital stay for patients with physical illnesses is longer for those with mental health comorbidity, particularly in the presence of severe physical multimorbidity. Integrating psychosocial risk screening at hospital admission, with a subsequent care pathway, could address psychosomatic and social care needs early and reduce length of stay. However, implementation may be hindered by organisational factors such as increased staff workload and timely integration into existing processes. In addition, patient factors such as low acceptance of screening and follow-up may affect uptake. This pilot study aims to assess the feasibility of implementing this integrated approach to screening and follow-up in preparation for a confirmatory trial.

Methods

The present study is a single centre, randomised feasibility study conducted on a pilot ward. Patients will be enrolled and assigned to the intervention or the control group. Only the intervention group will receive tablet-based psychosocial risk screening conducted by ward physicians or medical students in their practical year. If the psychosomatic screening is positive and the patient agrees, he or she is referred to the psychosomatic consultation service. If the social service screening is positive, the patient will be seen by a social worker. The main objective of this study is to assess the feasibility of conducting a full-sized confirmatory trial. An informed consent rate of 30% of eligible patients is set as the feasibility criterion. A study period of 4 months is planned for the feasibility study. The feasibility study will be analysed using descriptive statistics.

Ethics and dissemination

The study protocol was approved by the Ethics Committee of the Medical Faculty of Heidelberg University (S-301/2024) on 24 May 2024. The results of this feasibility study will be published in a peer-reviewed journal.

Applying medical hypnosis in the management of atopic dermatitis in children and young adolescents: study protocol for a pilot cluster randomised controlled trial (Hypno-AD)

Por: Thysebaert · Z. · Espagnon · C. · Bocquet · V. · Bruneau · L. · Miquel · J.
Introduction

Atopic dermatitis (AD) is a chronic inflammatory skin disease affecting up to 14% of the French children. Topical treatments are restrictive, leading patients to seek alternative options. Medical hypnosis may be a therapeutic approach, providing hypno-analgesia through comfort and soothing of the skin as well as anxiolysis by managing stress and boosting self-esteem. To date, only five studies have explored medical hypnosis in AD, showing promising results but limited by small sample sizes and lack of control arms. This study protocol describes the methodology for an initial evaluation of medical hypnosis within a therapeutic patient education (TPE) programme, called Hypno-DA.

Methods and analysis

The Hypno-Atopic Dermatitis (Hypno-AD) study is a prospective, monocentric, non-blinded, parallel, cluster-randomised controlled trial conducted at the University Hospital of La Reunion, France. The study commenced on 13 August 2024 and is scheduled to conclude on 13 August 2026. The primary objective is to assess the feasibility of recruiting for a medical hypnosis programme for children with mild-to-severe AD. 32 patients (aged 8–17 years) will be randomly allocated in a 1:1 ratio to receive TPE sessions combined with medical hypnosis (experimental arm) or the usual TPE sessions performed for AD without medical hypnosis (control arm). The experimental arm will employ a hypnosis-based intervention, referred to as the ‘superhero costume’ technique. Reinforcement will be provided through the practice of self-hypnosis at home, guided by listening to an audio recording provided on a Universal Serial Bus (USB) key. Secondary outcomes will be assessed at 1-month, 3-month and 6-month post-randomisation. These will include compliance with the required practice of self-hypnosis at home, rate of loss of follow-ups, patient satisfaction, effectiveness of the hypnosis programme on the control of AD (ADCT) and severity of AD (Patient-Oriented SCORing Atopic Dermatitis) and the global impression parents may have concerning the changes in their child’s AD.

Ethics and dissemination

Ethics approval was obtained from the Ile de France I Research and Institutional Ethics Committee (No. 2022-A01153-40). All methods were carried out in accordance with French law No. 2012-300 (5 March 2012) related to research involving humans as well as Good Clinical Practices (International Council for Harmonisation (ICH) version 4 of 9 November 2016, and the decision of 24 November 2006). Methods will conform to the Declaration of Helsinki. Informed oral consent from at least one legal guardian of each participant will be obtained in addition to oral consent from the child. Results will be published in an indexed peer-reviewed journal as well as presented and disseminated at scientific conferences.

Protocol RCT for active informed consent in spine and urologic surgery in the metropolitan city of Bologna: does an increased patient engagement improve satisfaction of complex surgical procedures?

Por: Boriani · L. · Quattrini · I. · Maccaferri · B. · Lima · C. · Benuzzi · A. · Salvador · M. · Schiavina · R. · Brunocilla · E. · Deiure · F. · Maselli · V. · De Stefano · R. · Vommaro · F. · Gasbarrini · A.
Introduction

Informed consent is an essential component of surgical care; however, patients often struggle to fully understand procedures, associated risks and available alternatives. Factors such as preoperative anxiety, limited health literacy and the complexity of consent documents can further impair comprehension and information retention. The active informed consent (CIA) pathway, based on a Patient Educational Program that combines multimedia resources with a comprehension test, aims to enhance patient understanding, improve satisfaction and reduce medicolegal issues.

Methods and analysis

The study will be conducted as a multicentre, non-pharmacological, randomised controlled trial in three hospitals in the Emilia-Romagna region (Italy). A total of 300 patients undergoing elective complex spinal surgery or robotic radical prostatectomy will be enrolled and randomised (1:1) to the experimental arm or to the standard informed consent arm, using block randomisation stratified by centre. Outcomes will include patient satisfaction (Client Satisfaction Questionnaire), comprehension, psychological distress (Depression Anxiety Stress Scales), pain (Numeric Rating Scale), functional recovery (Oswestry Disability Index/International Prostate Symptom Score/International Consultation on Incontinence Questionnaire Short Form/International Index of Erectile Function) and medicolegal complaints. Assessments will be performed at baseline (T0), discharge (T1), 2 months (T2) and 6 months (T3), with extended monitoring of medicolegal outcomes for up to 5 years.

Ethics and dissemination

The study has been approved by the Regional Ethics Committee of Emilia-Romagna (protocol CIA21, V.1.3 dated 14 December 2022). Participation is voluntary and does not affect standard care. Results will be disseminated through peer-reviewed journals, conference presentations and communication with health authorities. If effective, the intervention may be implemented as a scalable model to improve patient empowerment and transparency in surgical consent.

Careful ventilation in acute respiratory distress syndrome: the protocol of the CAVIARDS international multicentre randomised basket trial

Por: Coudroy · R. · Telias · I. · Jonkman · A. · Thille · A. W. · Diehl · J.-L. · Peron · N. · Ko · M. · Bourion · A.-A. · Tiribelli · N. · Fredes · S. · Gutierrez · M. · Manchado Bruno · A. · Vasquez · D. N. · Pratto · R. A. · Plotnikow · G. A. · Bianchini · F. · Accoce · M. · Dorado · J. · Sp
Introduction

Acute respiratory distress syndrome (ARDS) is a major public health problem, accounting for 23% of intubated patients and associated with high mortality rates. Although lifesaving, invasive mechanical ventilation can worsen lung injury when ventilator settings are poorly adjusted to lung physiology. We hypothesise that individualising ventilator settings via (1) the bedside assessment of lung recruitability using a one-breath derecruitment manoeuvre and measurement of airway opening pressure to set positive end-expiratory pressure (PEEP), (2) controlling the distending pressure and (3) controlling respiratory drive improves ARDS outcomes.

Methods and analysis

The CAreful Ventilation In ARDS trial is an investigator-led multicentre (33 centres in eight countries), open-label, randomised controlled basket trial comparing two ventilation strategies in two subpopulations of moderate-to-severe ARDS: induced or not by COVID-19. A total of 740 patients will be randomised (370 in each substudy) in a 1:1 ratio to individualised ventilator settings or to using traditional PEEP to inspired fraction of oxygen tables for PEEP setting. Indications for proning and weaning strategies are similar in both arms. The primary outcome is all-cause mortality at day 60. Secondary outcomes include duration of mechanical ventilation, duration of intensive care unit (ICU) and hospital stay, organ dysfunction, barotrauma and mortality in ICU, at day 28 and in hospital.

Ethics and dissemination

Ethics approval has been obtained for all participating centres: Unity Health Toronto Research Ethics Board (for three centres: St Michael’s Hospital, Toronto General Hospital and Toronto Western Hospital); Comité de Ética de Investigación con Medicamentos del Hospital Universitari Vall d’Hebron; Comité de protection des personnes Ile de France III; Comité d'Ética de la Investigatción con Medicamentos de la Fundació de Gestió Sanitària del Hospital de la Santa Creu i Sant Pau; Comitato Etico—Fondazione Policlinico Gemelli; Comitato Etico di Area Vasta Emilia Centro; NYU Langone Health Institutional Review Board; Comité Ético Científico de Ciencias de la Salud; Il Comitato Etico Area 1 dell’Azienda Ospedaliero-Universitaria ‘Ospedali Riuniti’ di Foggia; HIGA ‘Eva Perón’ Comité de Bioética; Comité de Revisión Institucional del Hospital Británico Comité de Ética en Investigación; Complejo Médico Churruca-Visca Comité de Ética Biomédica; Comité de Ética SATI Comité de Ética en Investigación; Comité de Ética en Investigación del CEMIC; Comité de Ética SATI Comité de Ética en Investigación; Medical Research Ethics Committees United.

Effectiveness of a co-adapted virtual discharge education app on disease knowledge and health behaviours in patients following heart attack: a multicentre, randomised controlled trial protocol in Sydney, Australia

Por: Zhang · L. · Shi · W. · Zhao · E. · Hyun · K. K. · Zecchin · R. · Gao · Y. · Brunorio · L. · Stanaway · F. · Ellis · T. · Redfern · J. · Clark · R. · Du · H. · Gallagher · R.
Introduction

Active self-management by patients following acute coronary syndrome (ACS) can reduce recurrent events. Patient education for transitioning from hospital to home promotes effective self-management but can be limited in the acute setting due to time and resource pressures. Patients from ethnic minority and immigrant backgrounds face additional language, cultural and health literacy barriers to receiving patient education. Self-administered virtual patient education presents an innovative solution to these challenges. This study aims to evaluate a co-adapted, virtual avatar nurse-guided, discharge education application (app) for Chinese-speaking patients following ACS.

Methods and analysis

This multicentre, assessor-blinded, randomised controlled trial will recruit 98 Chinese-speaking inpatients following ACS with evaluation at 1 and 3 months postdischarge. Control participants in the control group will receive the usual ward-based patient discharge education. Intervention participants will additionally receive the education app installed on their devices before hospital discharge with unlimited access during the study period. Cultural relevance and linguistic accuracy for this Chinese version of an existing app were ensured through co-adaptation with Chinese-speaking consumers; the primary outcome will be coronary heart disease (CHD) knowledge, and secondary outcomes will include knowledge, attitudes and beliefs regarding heart attack symptoms and responses, CHD self-management behaviours, utilisation of healthcare services and quality of life. A process evaluation will be conducted alongside the trial to assess the acceptability and feasibility of the app. Between-group comparisons will be made using 95% CIs, accounting for baseline differences using linear mixed effects or mixed effects logistic regression models.

Ethics and dissemination

The Western Sydney Local Health District Human Research Ethics Committee has approved this study protocol (26 February 2024, amendment number 2) (2024/STE00147), with site-specific authorisations obtained from each participating hospital. The results will be disseminated through peer-reviewed journal articles and presentations at scientific conferences.

Patient Agitation in the Intensive Care Unit: A Concept Analysis

ABSTRACT

Aim

Exploring the concept of patient agitation in the intensive care unit.

Background

Patient agitation in the intensive care unit is of widespread concern and linked to negative outcomes for patients, staff, and family members. There is currently no consensus on what constitutes agitation in the intensive care context, hindering effective and tailored prevention and management.

Design

Concept Analysis.

Method

Walker and Avant's eight-step concept analysis approach.

Data Sources

A comprehensive search was carried out in the databases MEDLINE, PsychINFO and CINAHL. A total of 32 papers published between 1992 and 2023 were included, reviewed, and analysed to explore definitions, attributes, antecedents and consequences of patient agitation.

Results

Patient agitation in the intensive care unit is characterised by excessive motor activity, emotional tension, cognitive impairment, and disruption of care, often accompanied by aggression and changes in vital signs. Antecedents encompass critical illness, pharmacological agents and other drugs, physical and emotional discomfort, patient-specific characteristics and uncaring staff behaviours. Consequences of agitation range from treatment interruptions and poor patient outcomes to the psychological impact on patients, families, and staff.

Conclusion

Agitation in the intensive care unit is a complex issue which significantly impacts patient treatment and clinical outcomes. For healthcare professionals, patient agitation can contribute to high workloads and job dissatisfaction. Due to the complex nature of agitation, clinicians must consider multifaceted strategies and not rely on medication alone. Further research is needed to fully understand patient agitation in the ICU. Such understanding will support the development of improved strategies for preventing and managing the behaviours.

Implications

A clearer understanding of patient agitation supports the development of tailored interventions that improve patient care, guide ICU training, and inform future research.

Decision Trees for Managing Impaired Physical Mobility in Multiple Trauma Patients

ABSTRACT

Aim

To develop and validate decision trees using conditional probabilities to identify the predictors of mortality and morbidity deterioration in trauma patients.

Design

A quasi-experimental longitudinal study conducted at a Level 1 Trauma Center in São Paulo, Brazil.

Method

The study analysed 201 patient records using standardised nursing documentation (NANDA International and Nursing Outcomes Classification). Decision trees were constructed using the chi-squared automatic interaction detection (CHAID) algorithm and validated through K-fold cross-validation to ensure model reliability.

Results

Decision trees identified key predictors of survival and mobility deterioration. Patients who did not require (NOC 0414) Cardiopulmonary Status but required (NOC 0210) Transfer Performance had a 97.4% survival rate. Conversely, those requiring (NOC 0414) Cardiopulmonary Status had a 25% risk of worsening mobility, compared to 9% for those who did not. K-fold cross-validation confirmed the model's predictive accuracy, reinforcing the robustness of the decision tree approach (Value).

Conclusion

Decision trees demonstrated strong predictive capabilities for mobility outcomes and mortality risk, offering a structured, data-driven framework for clinical decision-making. These findings underscore the importance of early mobilisation, tailored rehabilitation interventions and assistive devices in improving patient recovery. This study is among the first to apply decision trees in this context, highlighting its novelty and potential to enhance trauma critical care practices.

Implications for the Profession and/or Patient Care

This study highlights the potential of decision trees, a supervised machine learning method, in nursing practice by providing clear, evidence-based guidance for clinical decision-making. By enabling early identification of high-risk patients, decision trees facilitate timely interventions, reduce complications and support personalised rehabilitation strategies that enhance patient safety and recovery.

Impact

This research addresses the challenge of improving outcomes for critically ill and trauma patients with impaired mobility by identifying effective strategies for early mobilisation and rehabilitation. The integration of artificial intelligence-driven decision trees strengthens evidence-based nursing practice, enhances patient education and informs scalable interventions that reduce trauma-related complications. These findings have implications for healthcare providers, rehabilitation specialists and policymakers seeking to optimise trauma care and improve long-term patient outcomes.

Patient or Public Contribution

Patients provided authorisation for the collection of their clinical data from medical records during hospitalisation.

Identifying risk patterns for sudden cardiac death in athletes: A clustering and principal component analysis approach

by Giacinto Angelo Sgarro, Paride Vasco, Domenico Santoro, Luca Grilli, Marco Giglio, Natale Daniele Brunetti, Luigi Traetta, Giuseppe Cibelli, Anna Antonia Valenzano

Sudden Cardiac Death (SCD) is a critical and unexpected condition that occurs due to cardiac causes within one hour of the onset of acute cardiovascular symptoms or twenty-four hours in unwitnessed cases. Despite advancements in cardiovascular medicine, practical methods for predicting SCD are still lacking, and there are no standardized systems to identify individuals at risk, especially in seemingly healthy populations such as athletes. In this study, we employed hierarchical clustering and principal component analysis (PCA) on data from 711 competitive athletes, revealing distinct patterns and cluster distributions in PCA space. Specifically, Clustering revealed characteristic feature combinations associated with increased SCD risk in athletes. Notably, certain clusters shared traits, including participation in Class C sports, sinus tachycardia, ventricular pre-excitation, personal or family history of heart disease, T-wave inversions, and prolonged QTc intervals. PCA helped visualize these patterns in distinct spatial regions, highlighting underlying structures and aiding intuitive risk interpretation. These results enable scientists to derive cluster metrics that serve as reference points for classifying new individuals and visually representing risk patterns in a clear graphical format. These findings establish a foundation for predictive tools that, with additional clinical validation, could aid in the prevention of SCD. The dataset used in this study, along with the clustering and PCA results, is available to the scientific community in an open format, together with the necessary tools and scripts to enable independent experimentation and further analysis.

Schulthess Clinic Zürich Shoulder Instability Registry: a local registry for multimodal data collection and enhanced care

Por: Schneller · T. · Delliehausen · N. · Brune · D. · Böhm · E. · Moroder · P. · Lazaridou · A. · Scheibel · M.
Purpose

The Shoulder Instability Registry (SIR) was established in 2019 to systematically capture and monitor outcomes following surgical treatment of shoulder instability (SI). The aim of this cohort profile is to describe the purpose, design, data structure and baseline characteristics of the SIR, and to outline how the registry supports longitudinal assessment of safety, functional recovery, quality of life and patient-reported outcomes after surgical treatment of SI.

Participants

The registry includes all patients treated surgically for SI. Data collection includes medical history of instability, surgical techniques and intraoperative findings. Clinical assessments include range of motion, instability-specific tests, hyperlaxity signs, Constant Score, subjective shoulder value and SI-specific scores such as the ROWE Score and the Western Ontario Shoulder Instability Index. Radiological evaluations included initial and follow-up imaging via X-rays and CT to assess bony lesions and SI-related arthropathy, as well as MRI for soft tissue injuries. Data are documented preoperatively, at 6 months and at 24 months postoperatively. Although the SIR is an observational cohort rather than a randomised clinical trial, treatment effectiveness is evaluated through longitudinal changes in validated patient-reported outcomes, clinical performance measures and imaging findings.

Findings to date

Between January 2019 and December 2024, 668 patients have been registered (mean age 31 years, 82% men, mean body mass index of 25). According to the American Association of Anesthesiology (ASA) Classification, 66% of patients were classified as ASA I, 33% as ASA II and only 1% as ASA III. 69% of admissions were due to accidents and 31% due to illness. Mean surgery duration was 75 min, and the median hospital stay was 2 days. 38% of patients were insured privately and had general insurance in 62%. 85% of cases were treated arthroscopically, and 15% were treated openly. Baseline clinical scores showed a mean Constant Score of 77 points, mean subjective shoulder value of 49%, mean ROWE Score of 46 points and mean Western Ontario Shoulder Instability Index of 53. Based on Gerber’s classification, 68% of cases were type B2, 29% B3, 2% B5 and fewer than 2% were classified as B4 or B1. 85% of cases suffered from anterior instability, while only 13% experienced posterior instability, the remaining 2% showed multidirectional instability. Among posterior cases, Moroder’s classification identified 58% as type B2, 19% as A2, 7% as A1, 6% as B1, 6% as C1 and 4% as C2. Regarding osteochondral lesions, 20% showed none, 31% showed a glenoid defect, 54% showed a Hill-Sachs lesion and 13% showed a cartilage defect. Scheibel’s classification identified glenoid defects as type 3a in 38% of cases, type 2 in 24%, type 1a in 13% of cases, type 3b in 11%, type 1b in 8% and type 1c in 5% of cases. Positive Gagey and Walch signs were observed in 29% and 27% of cases, respectively. Dislocations presented as primary events in 24% of cases, while 76% were recurrent. Surgical interventions included 459 (70%) Bankart repairs, 6 Bankart plus repairs (

Future plans

We will continue prospectively enrolling and monitoring patients that receive surgical treatment of SI. There are no current plans to halt the data collection in the near future, thereby consistently increasing the number of patients in the registry. A larger availability of data will additionally allow us to apply machine learning modelling and develop risk-prediction tools with the goal of aiding surgical decision making.

Evaluation of visual patient predictive for enhancing level 3 situation awareness: protocol for a multicentre randomised computer-based simulation and diagnostic accuracy study (true positive rate, precision, average lead time)

Por: Hunn · C. A. · Bruns · H. · Sahli · S. · Wachtendorf · L. · Schäfer · J. · Schwerin · S. · Delis · A. · Kalisch · M. · Dugac · G. · Rahrisch · A. · Ebensperger · M. · Karimitar · A. · Massoth · G. · Neuhaus · C. · Dubatovka · A. · Nöthiger · C. B. · Gasciauskaite · G. · Roche · T. R.
Introduction

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.

Methods and analysis

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.

Ethics and dissemination

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.

Association between carotid-femoral pulse wave velocity and cardiovascular disease in individuals with moderate blood pressure: a systematic review and individual participant meta-analysis

Objectives

The predictive value of carotid-femoral pulse wave velocity (cfPWV) for cardiovascular (CV) events in individuals with blood pressure (BP) 120–159/80–99 mm Hg, where more accurate risk stratification has the greatest clinical effect, is unknown. This study aims to determine whether cfPWV improves the prediction of CV events beyond traditional risk factors in individuals with moderate BP.

Design

A systematic review and meta-analysis.

Data sources

PubMed and EMBASE were searched through April 2023.

Eligibility criteria

We included prospective, population-based cohort studies with ≥1 year follow-up that directly measured cfPWV as an index of arterial stiffness and reported incident CV disease (CVD), atherosclerotic CVD (ASCVD), coronary heart disease, stroke or all-cause mortality outcomes.

Data extraction and synthesis

Individual participant data from 11 cohorts (n=15 987) were harmonised and analysed using two-stage random-effects meta-analysis. Incremental predictive and clinical utility analyses compared 10-year risk models with and without cfPWV.

Results

There were 1279 first atherosclerotic CV events over a median follow-up of 9.9 years. A 1-SD increase in loge(cfPWV) was associated with a 1.21-fold (95% CI 1.08 to 1.36) increase in risk of ASCVD. Adding cfPWV to traditional risk factors improved ASCVD prediction: change in discrimination (C-index): 0.0048 (95% CI 0.0002 to 0.0094), p=0.041. In hypothetical populations of 100 000 individuals with moderate BP, cfPWV-guided treatment could reduce event rates by 2.7% and 3.1% under European and US guidelines, respectively.

Conclusions

Adding cfPWV to traditional CV risk factors may improve the prediction and classification of first CV events in individuals with moderate BP. Additional screening with cfPWV could enhance risk stratification for antihypertensive treatment initiations.

Adjunctive bright light therapy to enhance continuous positive airway pressure adherence in patients with comorbid major depressive disorder and obstructive sleep apnoea syndrome: study protocol for a randomised sham-controlled trial

Por: El Azzaoui · H. · Catoire · S. · Lecharpentier · H. · Felician · J. · Grasset · O. · Gronfier · C. · Vallet · W. · Damato · T. · Brunelin · J.
Introduction

Obstructive sleep apnoea syndrome (OSAS) co-occurs with major depressive disorder (MDD) in approximately 50% of cases, and this comorbidity is associated with greater severity of depressive symptoms, sleep disturbances and poorer clinical outcomes. Although continuous positive airway pressure (CPAP) therapy is effective in treating OSAS and alleviating symptoms of MDD, poor adherence during the initial weeks of treatment remains a major clinical challenge. Bright light therapy has been shown to rapidly improve sleep, wakefulness, cognitive function and mood in patients with MDD. Given these complementary mechanisms, we propose that combining CPAP with bright light therapy may enhance patient adherence during the critical initial phase of CPAP treatment, ultimately leading to better clinical and sleep-related outcomes.

Methods and analysis

In a single-centre, double-blind, sham-controlled study with two parallel arms, 130 patients with both MDD and OSAS requiring CPAP therapy will be randomly assigned to receive either 14 sessions of 30 min active bright light therapy (n=65, 1200 Lux, peak wavelength at 500 nm) or 14 sessions of 30 min sham bright light therapy (n=65, 33 Lux, peak wavelength at 600 nm) during the first 2 weeks, following CPAP initiation at home. The primary outcome will be adherence to CPAP (in hours per 24 hours during the 14 days of investigation). Secondary clinical outcomes will include changes in depressive and anxiety symptoms. Secondary sleep-related outcomes will include both objective sleep parameters (polysomnography, melatonin and actimetry) and standardised psychometric scales. The persistence of treatment effects at 1-month follow-up will also be evaluated.

Ethics and dissemination

The study was approved by an ethics committee (CPP Nord Ouest IV, Lille, France), and the French National Agency for Medicines and Health Products Safety registration number 2024-A01551-46. The findings will be disseminated through international peer-reviewed publications, presentations at scientific conferences and outreach at public conferences.

Delays in cancer diagnosis for patients with non-specific symptoms (NSSs) lead to poorer outcomes. Rapid Diagnostic Clinics (RDCs) expedite care, but most NSS patients do not have cancer, highlighting the need for better risk stratification. This study aimed to develop biomarker-based clinical prediction scores to differentiate high-risk and low-risk NSS patients, enabling more targeted diagnostics.

Design

Retrospective and prospective cohort study.

Setting

Secondary care RDC in London.

Participants

Adult patients attending an RDC between December 2016 and September 2023 were included. External validation used data from another RDC.

Outcome measures

The primary outcome was a cancer diagnosis. Biomarker-based risk scores were developed using Latent Class Analysis (LCA) and Least Absolute Shrinkage and Selection Operator (LASSO). Model performance was assessed using logistic regression, receiver operating characteristic curves (AUROC) and decision curve analysis.

Results

Among 5821 RDC patients, LCA identified high white cell count, low haemoglobin, low albumin, high serum lambda light chain, high neutrophil-to-lymphocyte ratio, high serum kappa light chain (SKLC), high erythrocyte sedimentation rate (ESR), high C-reactive protein (CRP) and high neutrophils as cancer risk markers. LASSO selected high platelets, ESR, CRP, SKLC, alkaline phosphatase and lactate dehydrogenase. Each one-point increase in score predicted higher odds of cancer (LCA: AOR 1.19, 95% CI 1.16 to 1.23; LASSO: AOR 1.29, 95% CI 1.25 to 1.34). Scores ≥2 predicted significantly higher cancer odds (LCA: AOR 3.79, 95% CI 2.91 to 4.95; LASSO: AOR 3.44, 95% CI 2.66 to 4.44). Discrimination was good (AUROC: LCA 0.74; LASSO 0.73). External validation in 573 patients confirmed predicted increases in cancer risk per one-point LASSO score rise (AOR 1.28, 95% CI 1.15 to 1.42), with a borderline increase for LCA (AOR 1.16, 95% CI 1.06 to 1.27).

Conclusion

Biomarker-based scores effectively identified NSS patients at higher cancer risk. LCA captured a broader biomarker range, offering higher sensitivity, while LASSO achieved higher specificity with fewer markers. These scores may also help detect severe benign conditions, improving RDC triage. Further validation is needed before broader clinical implementation.

Introduction

Photobiomodulation (PBM) has shown promising effects in managing postoperative pain following conventional periapical surgery, although current evidence remains limited. This study aims to assess the effect of PBM on postoperative pain 24 hours after periapical surgery.

Methods and analysis

A randomised, controlled, double-blind trial will include 34 patients undergoing periapical surgery in the maxillary region, randomly assigned to an experimental group (n=17) or control group (n=17). The experimental group will receive PBM (GaAlAs diode laser, 808 nm, 100 mW, 4 J/cm², applied at five vestibular points) and placebo ibuprofen immediately and 24 hours postoperatively. The control group will receive simulated PBM and active ibuprofen. The primary outcome is postoperative pain assessed by the visual analogue scale at 24 hours. Secondary outcomes include pain at the seventh day, paracetamol intake, oedema, ecchymosis, soft tissue status and temperature at 24 hours and 7 days. Radiographic evaluation of healing will be performed at 1 and 3 months. Statistical analysis will be conducted based on data distribution, using repeated measures ANOVA (Analysis of Variance) or non-parametric equivalents for longitudinal outcomes, and appropriate tests for categorical variables. Significance will be set at p

Ethics and dissemination

The study was approved by the Human Research Ethics Committee of Universidad Católica del Uruguay (process no. 220914). Results will be disseminated to participants, healthcare professionals, the public and scientific communities.

Introduction

Leishmaniases are a group of vector-borne diseases caused by parasites of the genus Leishmania, which are renowned for increasing global spread due to factors like climate change, globalisation, urbanisation and migration. Leishmaniasis is classified as a neglected tropical disease but is endemic in several areas of the Mediterranean Basin, including Italy, where Leishmania infantum is most involved as the parasite, phlebotomine sand fly as the vector and dog as the principal reservoir. Effective surveillance of communicable infectious diseases is a goal worldwide for organisations such as the WHO and for local and national governments but is an unfulfilled objective. Even in Italy and particularly in the region of Tuscany, despite mandatory reporting, significant gaps each year are identified between reported cases and hospital admissions. By estimating the underreporting of confirmed human leishmaniasis cases, this protocol aims to suggest actions to strengthen the current epidemiological surveillance system to enable timely and effective public health intervention in human and veterinary populations.

Methods and analysis

This retrospective multicentre study, conducted in the Central Tuscany Health District, the most populous area of the Tuscany region with approximately 1.6 million inhabitants, is based on the analysis of data collected from 2014 to 2024 using diagnostic laboratory, hospital and regional information system sources. The primary objective is to estimate the degree of underreporting of leishmaniasis in this area through the application of capture-recapture models. The secondary objective is to analyse the clinical and demographic characteristics of individuals diagnosed as confirmed leishmaniasis cases between January 2014 and December 2024, as well as to perform a geolocation analysis of the cases. The study includes the entire population, both adult and paediatric, of the Central Tuscany Health District who underwent laboratory testing for leishmaniasis (serological tests identifying the presence of antibodies; parasitological examination with evidence of amastigotes in aspirates, smears or biopsy sections; culture examination of aspirates, biopsies and/or peripheral blood positive for the presence of promastigotes; identification of Leishmania nucleic acid in aspirates, biopsies and/or peripheral blood samples via molecular diagnosis).

Ethics and dissemination

The study is being conducted in accordance with the protocol approved by the Ethics Committee of the Tuscany Region – Pediatrics Section, in November 2024. Ethics Committee opinion register number: 219/2024. Because the study uses only pseudonymised, routinely collected administrative and laboratory data with no direct patient contact or intervention, individual informed consent was not required, as confirmed by the Ethics Committee. Findings will be submitted to a peer-reviewed journal, presented at international conferences and presented at stakeholder workshops.

Introduction

Over 777 million COVID-19 infections have occurred globally, with data suggesting that 10%–20% of those infected develop Long COVID. Fatigue is one of the most common and disabling symptoms of Long COVID. We aim to assess the feasibility and safety of a new, remotely delivered, multimodal rehabilitation intervention, paced to prevent post-exertional malaise (PEM), to support the conduct of a future, definitive randomised trial.

Methods and analysis

We will conduct a randomised, two-arm feasibility trial (COVIDEx intervention vs usual care). Sixty participants with Long COVID will be recruited and randomised prior to giving informed consent under a modified Zelen design using 1:1 allocation with random permuted blocks via central randomisation to receive either the COVIDEx intervention or usual care. The 50-minute, remotely delivered, COVIDEx intervention will occur twice weekly for 8 weeks. All participants will wear a non-invasive device throughout their entire study participation, to track heart rate, blood oxygen saturation, steps, sleep and monitor PEM. The primary feasibility objectives will be recruitment rates, intervention fidelity, adherence, acceptability (intervention and design), retention, blinding success and outcome completeness. Secondary objectives will include refined estimates for the standard deviation and correlation between baseline and follow-up measurements of fatigue. Feasibility and clinical outcomes will be collected at baseline, 4, 8, 12 and 24 weeks. Qualitative interviews with participants and physiotherapists will explore intervention acceptability and barriers/facilitators.

Ethics and dissemination

Ethical approval for this study was obtained by the Western University Health Sciences Research Ethics Board (REB# 123902). Dissemination plans include sharing of trial findings at conferences and through open access publications and patient/community channels.

Developing consolidated guidelines for reporting and evaluation of studies using transcranial electrical stimulation (CoRE-tES): protocol for an international Delphi study and expert consensus process

Por: Suhood · A. Y. · Summers · S. · Pascual-Leone · A. · Nitsche · M. A. · Ziemann · U. · Bikson · M. · Lefaucheur · J.-P. · Brunoni · A. R. · Bestmann · S. · Chipchase · L. S. · Razza · L. B. · Cavaleri · R.
Introduction

In recent decades, transcranial electrical stimulation (tES) has become a widely used non-invasive method for modulating brain function in clinical and non-clinical populations. However, existing tES trials exhibit substantial methodological heterogeneity, often limiting the reproducibility and interpretability of findings. There currently exists a paucity of consensus-driven, standardised recommendations outlining the key factors that should be reported and/or controlled in tES studies. Accordingly, this project aims to develop Consolidated Guidelines for Reporting and Evaluation of studies using tES (CoRE-tES), a tool designed to assess the methodological quality and reporting of laboratory-based and home-based tES studies. These guidelines will support improved quality, consistency, replication and transparency in research involving tES modalities, including transcranial direct current stimulation, transcranial alternating current stimulation and transcranial random noise stimulation.

Methods and analysis

CoRE-tES will be developed and disseminated over five stages. Stage 1 will comprise a review of recent tES literature to assess methodological and reporting quality. Stage 2 will employ a Delphi process to seek agreement among international tES experts on a list of items for inclusion in CoRE-tES. In stage 3, a consensus meeting will be held to synthesise and prioritise the agreed items to form CoRE-tES. Stage 4 will involve production of the final CoRE-tES checklist and an accompanying evaluation and elaboration document. In stage 5, CoRE-tES will be disseminated via journal publication, conferences, professional meetings and social media campaigns.

Ethics and dissemination

Ethics approval has been obtained from the Western Sydney University Human Research Ethics Committee (approval number H16803). Findings will be disseminated through scientific conferences and peer-reviewed journal publications, and CoRE-tES will be indexed on the Enhancing the QUAlity and Transparency Of health Research Network website.

Consent for transfusion: global practices, documentation and patient understanding - a scoping review protocol

Por: Pereira · V. C. · Bezerra Salviano · F. W. · Brunetta · D. M. · Cipolotti · R.
Introduction

Patient involvement in healthcare has become increasingly important, not only as an expression of respect for autonomy but also as a means of empowering individuals to safeguard their care. In blood transfusion, informed consent is a critical tool for shared decision-making. This protocol outlines a scoping review to map how transfusion consent processes and forms are used globally and to characterise their key features. We aim to identify technologies used to obtain consent, evaluate compliance with international recommendations, describe practices in special populations and examine patients’ and families’ understanding of the consent process.

Methods and analysis

Following the Joanna Briggs Institute methodology, we will search PubMed, Embase, LILACS, Web of Science and Scopus; grey literature will be explored via Google Scholar and the Open Access Theses and Dissertations platform. No language or date restrictions will be applied. Reference lists of included studies will also be screened. Two reviewers will independently screen studies and chart data; disagreements will be resolved by a third reviewer. Synthesis will be diagrammatic/tabular with structured narrative, reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses: extension for Scoping Reviews. Where data allow, findings will be stratified by clinical setting. A stakeholder consultation with two transfusion medicine experts and two patient representatives will be undertaken to validate and refine interpretations.

Ethics and dissemination

Only publicly available sources will be used; research ethics approval is not required. Findings will be submitted to a peer-reviewed journal and presented at scientific meetings.
