Objectives

To develop and user-test a patient decision aid for people diagnosed with degenerative cervical myelopathy and who are considering surgery.

Design

Mixed-methods study describing the development of a patient decision aid.

Setting

A draft decision aid was developed by a multidisciplinary steering group (including study authors with degenerative cervical myelopathy, health professionals and researchers) informed by the best available evidence, authorship consensus and existing patient decision aids.

Participants

Patient-participants and health professional-participants who manage people with degenerative cervical myelopathy were recruited through social media and the steering group’s research and practice network. Quantitative questionnaires were used to gather baseline data, descriptive feedback, refine the decision aid and assess its acceptability. Qualitative semi-structured interviews were conducted online to gather feedback on the decision aid and were analysed using reflexive thematic analysis.

Results

We conducted 32 interviews: 19 patient-participants and 13 health professional-participants who manage people with degenerative cervical myelopathy (neurosurgeons, neurologists, physiotherapists, orthopaedic surgeons, general practitioners, rehabilitation and pain specialists and consultant occupational physicians and chiropractors). Participants were from 10 countries (Australia, Canada, Cyprus, Germany, Ireland, New Zealand, Sweden, Switzerland, United Kingdom and USA). Most participants rated the decision aid’s acceptability as good-to-excellent and agreed with most aspects of the decision aid (eg, defining degenerative cervical myelopathy, management recommendations, potential benefits and harms, questions to consider asking a health professional).

Conclusion

Our patient decision aid was rated as an acceptable tool by both health professional-participants who treat degenerative cervical myelopathy and patient-participants with lived experience of degenerative cervical myelopathy. This decision aid can be used by clinicians and people with degenerative cervical myelopathy to help with shared decision making following a diagnosis of degenerative cervical myelopathy. A study testing the potential benefits of this decision aid in a clinical setting is recommended.

The transition from winter to spring has an impact on the airway metabolome profile of asthmatic horses

by Julia Drespling, Steffen Heelemann, Selina Strathmeyer, Heike Kühn, Bianca Schwarz, Lars Mundhenk

Equine asthma is a chronic, non-infectious inflammatory disease of the lower airways in horses, classified as mild to moderate (MEA) or severe (SEA). Its pathogenesis is not fully understood and is influenced by environmental and seasonal factors. In this cross-sectional study, seasonal effects on the bronchoalveolar lavage fluid (BALF) metabolome were investigated in asthmatic and non-asthmatic horses. The metabolome of 230 BALF samples from horses across different seasons, classified as cytologically unremarkable (CUA), MEA, or SEA, was analyzed using proton nuclear magnetic resonance spectroscopy (1H-NMR). Principal component analysis was performed for each season, and metabolite profiles were statistically compared between seasons within each group. Altered metabolites were subjected to pathway enrichment analysis using the FELLA R package. Asthmatic horses showed significant seasonal changes in metabolite concentrations between warm and cold seasons, whereas only trends were observed in CUA horses. Pathway analysis indicated enrichment of cholesterol metabolism across all groups. The mTOR signaling pathway was only enriched in SEA horses. Several metabolites—including valine, taurine and carnitine —were altered during the transition from winter to spring in asthmatic horses. These findings indicate that the winter to spring transition significantly modulates the airway metabolome in asthmatic horses, particularly in SEA-affected animals.

Efficacy, moderators and mediators of cognitive behavioural analysis system of psychotherapy (CBASP) versus behavioural activation (BA) in persistently depressed treatment-resistant inpatients: study protocol for the multicentre, randomised controlled cha

Por: Brakemeier · E.-L. · Klein · J. P. · Zimmermann · J. · Hollandt · M. · Reinhard · M. A. · Boger · S. · Daldrup · L. · Eldem · L. · Gebhardt · P. · Heinrich · S. · Hirsmueller · M. · Millerowski · J. · Richter · M. · Ridderbusch · I. C. · Suerig · S. · Schroeter · L. · Velten-Schurian
Introduction

Up to 30% of individuals with depression develop persistent depressive disorder (PDD), an often disabling and difficult to treat condition. The Cognitive Behavioural Analysis System of Psychotherapy (CBASP) is the only psychotherapy developed specifically for treating individuals with PDD. While several randomised controlled trials (RCTs) have demonstrated its efficacy in outpatient settings, evidence for its use in inpatient settings remains limited. Pilot studies of CBASP inpatient programmes in Germany have shown promising feasibility and effectiveness; however, no RCTs to date have systematically evaluated their outcomes. This study represents the first RCT to compare the short- and long-term efficacy and safety of CBASP with Behavioural Activation (BA), a first-line psychotherapy for depression, within an intensive multimodal inpatient setting.

Methods and analysis

In this prospective, multicentre, rater-blinded RCT with an active control group, we aim to recruit 396 adults (aged 18–70 years) with treatment-resistant PDD at eight German university hospitals. Participants will be randomly assigned to receive either (1) CBASP or (2) BA within an intensive treatment programme consisting of 10 weeks acute treatment in an inpatient and/or day clinic setting, followed by 6 weeks of outpatient continuation treatment. Primary and secondary outcome assessments will be conducted at multiple time points: baseline (T0), treatment onset (T1), after 5 and 10 weeks of acute treatment (T2, T3), at the end of continuation treatment (T4, week 16) and every 2 months up to week 64 (T5, naturalistic follow-up).

The primary outcome measure will be the change in depression severity, as assessed by the Hamilton Depression Rating Scale (24-item version), after 16 weeks of treatment (from T0 to T4). Secondary outcomes will include response, remission, deterioration and relapse rates, self-reported depression and anxiety symptoms and additional psychological variables. A cost-benefit analysis will evaluate the health-economic benefits of both interventions. Additionally, this RCT will explore personalised treatment selection and mechanisms of change, including potential moderators and mediators of treatment effects. The findings from this trial are expected to provide clinicians with evidence-based guidance on choosing CBASP versus BA for inpatients with treatment-resistant PDD.

Ethics and dissemination

This study has received ethical approval from the ethics committees of all participating university hospitals. All participants will provide written informed consent before enrolment. Study findings will be published in peer-reviewed journals and presented at national and international conferences. We have involved people with lived experience from the earliest pilots onward, using their feedback to refine our study design. Ongoing consultation at conferences and public events has further ensured that our research remains grounded in patient perspectives.

Factors associated with fatigue in patients with systemic lupus erythematosus in an outpatient tertiary care setting: a cross-sectional cohort study

Por: Chapman · M. · Rizvi · A. M. · Qutab · M. · Munday · A. · Biehl · A. · Manna · Z. · Hasni · S.
Objectives

Fatigue is one of the most common and debilitating symptoms experienced by patients with systemic lupus erythematosus (SLE). Previous studies revealed the association of fatigue with various SLE and non-SLE-related factors. This study aims to explore the prevalence of fatigue and the factors that are associated with fatigue experienced by SLE patients in an outpatient rheumatology clinic setting.

Design

Prospective, observational study using a sample of convenience.

Setting

Outpatient rheumatology clinic at a tertiary care centre.

Participants

Consecutive subjects with SLE presenting for their outpatient visits enrolled in the ongoing Institutional Review Board-approved ‘Pathogenesis and Natural History of SLE’ protocol.

Primary and secondary outcome measures

Disease activity and organ damage accrual were measured by Safety of Estrogens in Lupus Erythematosus: National Assessment Version of the Systemic Lupus Erythematosus Disease Activity Index (SELENA-SLEDAI) and Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SLICC/ACR DI), respectively. Fatigue was measured by the self-reported Fatigue Severity Scale (FSS), and a score of ≥4 was used to define clinically significant fatigue. Correlation analyses were done to determine the association between fatigue and patient demographics, and SLE disease activity and damage indices. Results were considered as statistically significant at p

Results

183 patients completed the study, with a significant proportion (144/183) belonging to ethnic minorities. The overall FSS score was mean (±SD) 4±1.8 and SELENA-SLEDAI score of 3±2.6. The group reporting significant FSS scores ≥4 (N=95) included a higher proportion of White patients, more organ damage (SLICC/ACR DI score mean (±SD) 1.9±1.9) and higher body mass index (BMI) mean (±SD) 29.6±6.7 kg/m2; as compared with the group with FSS scores 2 (p=0.03).

Conclusions

Our study found that organ damage accrual, specifically pulmonary fibrosis and neuropathy as measured by SLICC-ACR DI and high BMI, is associated with clinically significant fatigue in SLE. Furthermore, our results support previous findings that fatigue is independent of SLE disease activity. Findings of our study need to be replicated in independent SLE cohorts measuring fatigue at multiple time points. Mechanistic studies are needed to better understand pathogenesis of fatigue in SLE.

How to assess the quality of research in nursing

Por: Mannethodi · K. · Nashwan · A. J.
Introduction

Understanding the quality of published research is essential for nurses, educators and healthcare researchers striving to implement evidence-based practice. However, ‘quality assessment’ can seem abstract or overly technical, primarily for those new to research appraisal. In an era where clinical decisions and policy recommendations are increasingly data-driven, evaluating the methodological rigour of quantitative studies is more critical than ever.1

High-quality research provides trustworthy, valid and ethically sound conclusions. In contrast, poorly conducted studies can lead to misguided clinical decisions, suboptimal patient care and inefficient resource use.2 This article clarifies quality assessment in quantitative nursing research, introduces common appraisal tools, outlines key domains and provides guidance for interpreting study quality confidently.

What is quality assessment in research?

Quality assessment involves evaluating a study’s design, methodology and reporting to determine its risk of bias and trustworthiness.3 This process typically follows literature...

Ethnic disparities in prostate cancer diagnosis: black men at greater risk following a PSA test in the UK

Por: Nashwan · A. J. · Mannethodi · K.

Commentary on: Down L, Barlow M, Bailey SER, et al. Association between patient ethnicity and prostate cancer diagnosis following a prostate-specific antigen test: a cohort study of 730,000 men in primary care in the UK. BMC Med 2024 Mar 1;22(1):82.

Implications for practice and research

  • Clinicians should consider ethnic differences when interpreting prostate-specific antigen test results, particularly for black men, to ensure timely prostate cancer diagnosis and avoid overtreatment or undertreatment.

  • Further studies are needed to explore genetic, environmental and healthcare access factors that contribute to ethnic differences in prostate cancer incidence and progression.

  • Context

    Prostate cancer is a common cancer worldwide, with incidence and mortality varying significantly across ethnic groups.1 2 Black men are at a higher risk of prostate cancer diagnosis and death, while Asian men are at a lower risk compared with white men.3...

    Non-randomised trial of a hepatitis C same-day test and treat model using antibody test only for people who inject drugs in Armenia, Georgia and Tanzania: a CUTTS HepC study protocol

    Por: Draper · B. L. · Flynn · M. · Schroeder · S. · Wisse · E. · Aikaeli · F. · Han · Z. M. · Ayako · M. · Bajis · S. · Butsashvili · M. · Davtyan · K. · Kordzadze · T. · Lamand · P. · Luhmann · N. · Sargsyan · K. · Senkoro · M. · Scott · N. · Stone · J. · Vickerman · P. · Voloshin · A. · Walker
    Introduction

    Despite the availability of curative treatments, hepatitis C diagnosis and treatment coverage is suboptimal globally with few countries on track to achieve the WHO’s 2030 elimination targets. In 2022, an estimated 50 million people were living with hepatitis C, with 1 million new infections annually. Most people living with hepatitis C reside in low- and middle-income countries, and people who inject drugs are disproportionately affected by hepatitis C.

    Continuing simplification of diagnostic pathways and treatment care models is required to improve linkage to care and reduce costs associated with hepatitis C treatment and cure.

    Methods and analysis

    This study is a multi-country non-randomised, quasi-experimental, prospective comparative two-arm trial. It aims to assess the feasibility of implementation, retention in hepatitis C care and achievement of cure and cost-effectiveness outcomes, comparing two simplified hepatitis C testing and treatment pathways.

    Arm 1 is a standard simplified test and treat model of care following global guidance, and arm 2 is an innovative rapid, same-day treatment initiation model of care using a presumptive treatment approach based on shortened read-time of the point-of-care OraQuick hepatitis C antibody test result. Secondary outcomes include assessing the accuracy of the OraQuick hepatitis C antibody test in predicting viraemia and the acceptability of each pathway.

    This study will be implemented in Armenia, Georgia and Tanzania. Treatment-naïve people who inject drugs aged over 18 years in each country will be eligible for enrolment.

    Recruitment commenced in October 2024 in Armenia, June 2025 in Georgia and August 2025 in Tanzania and is anticipated to close by December 2026.

    Ethics and dissemination

    This trial has been reviewed by WHO Ethics Review Committee (ERC), Alfred Hospital Ethics Committee (Australia) and local country ERCs. Alongside journal publications and conferences, the results from this study will be disseminated through summary reports and workshops with key stakeholders and with communities of people affected by HCV through relevant organisations/networks, including the global Community Advisory Board (CAB). The study results will inform national scale-up of simplified care models and inform potential pathways for further simplification of care models, including the potential for one-step diagnostic pathways and same-day treatment in particular scenarios for the three study countries, and other low- and middle-income countries globally.

    Design and rationale of the EFFORTII project: a multicentric randomised-controlled trial on the impact of continued nutritional therapy at hospital discharge

    Por: Wunderle · C. · Tribolet · P. · Kaegi-Braun · N. · Haller · V. · Escher · R. · Aujesky · D. · Trennepohl Da Costa Heinen · G. · Brändle · M. · Bregenzer · T. · Henzen · C. · Zehnder · T. · Schait · S. · Gassmann · C. · Dorfschmid · M. · Ballesteros-Pomar · M. D. · Cuerda · C. · Burgo
    Introduction

    Malnutrition is a highly prevalent chronic condition that contributes to higher morbidity and mortality in patients with multiple comorbidities. While positive effects of nutritional therapy in the in-hospital setting have recently been demonstrated, the benefits of long-term nutritional therapy after hospital discharge remain uncertain. Herein, we outline the design and rationale of the EFFORTII trial, the largest nutritional trial to date to assess the effects of continued nutritional support after hospital discharge in medical patients, with particular attention to key design decisions regarding nutritional strategy, patient selection criteria and study endpoints.

    Methods and analysis

    The Effect of Continued Nutritional Support at Hospital Discharge on Mortality, Frailty, Functional Outcomes and Recovery (EFFORTII) is an investigator-initiated, non-commercial randomised controlled trial designed to evaluate whether ongoing, individualised nutritional therapy after hospital discharge—targeted to meet specific energy and protein requirements—offers a cost-effective approach to lowering mortality, minimising complications and maintaining functional status compared with standard care. Eligible participants are adult, chronically ill medical inpatients at risk of malnutrition. Patients in the intervention group receive individualised nutritional therapy delivered by an experienced dietitian through a combination of telemedicine and in-person consultations. The intervention aims to meet personalised nutritional targets, supported by a trained dietitian. Control group patients receive nutritional counselling at discharge, but no structured nutritional management during follow-up. We designed the trial as an event-driven trial with a target of 247 mortality events (primary endpoint), which will be assessed over approximately 5 years until event-driven endpoint is met. The minimum total sample size is at least 802 participants, based on the assumed treatment HR of 0.70. The main trial is enrolling patients across multiple sites in Switzerland. During the trial, additional sites in Spain joined the study, and their data will be analysed using a patient-level pooled approach.

    Ethics and dissemination

    This study involves human participants and was first granted ethical approval by the Ethics Committee Northwest- and Central Switzerland and then by all participating local ethics committees. Written informed consent will be obtained from all participants. Findings will be disseminated in peer-reviewed journals and academic conferences.

    Psychosocial risk screening in the inpatient care of physically ill patients: study protocol for a feasibility study

    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.

    PRECISION study: impact of personalised cardiac anaesthesia and cerebral autoregulation on neurological outcomes in patients undergoing cardiac surgery - protocol for an international, multicentre, prospective cohort study

    Por: Gomes · N. V. · Edgar-Whelan · H. · Beqiri · E. · Young · J. · Schindler · C. · Gregor · M. · Erb · J. M. · Siegemund · M. · Kuhle · J. · Maleska Maceski · A. · Needham · E. · Cichon · S. · Burger · B. · Monsch · A. U. · Hasemann · W. · Wüest · A. · Fassl · J. · Kaiser · H. A. · Hight · D
    Introduction

    Adverse neurological complications, including postoperative delirium (POD) and stroke, remain one of the major risks after cardiac surgery. A lack of comprehensive knowledge about their causes and neuroprotective strategies has hindered the development of effective interventions to reduce these events. Personalised cerebral autoregulation (CA)-oriented blood pressure monitoring aims to identify blood pressure targets tailored to each individual patient, thereby reducing brain injury. The PRECISION study aims to assess whether perioperative duration and magnitude of mean arterial pressure (MAP) deviation from an individual’s CA limits are associated with adverse neurological complications.

    Methods and analysis

    This international, multicentre, prospective cohort study is conducted at two Swiss and one British hospital. Patients aged 65 years or older undergoing elective primary or re-operative coronary artery bypass graft and/or valvular and/or ascending aorta surgery requiring cardiopulmonary bypass are included. Preoperatively, the patient’s baseline of physical, cognitive and mental status is established. Intraoperatively, near-infrared spectroscopy (NIRS) and transcranial Doppler (TCD) are recorded in real-time to generate NIRS-derived and TCD-derived CA indices. The primary endpoint is POD, assessed daily on postoperative days 0 to 7 or up to discharge, whichever occurs earlier with the 3D-Confusion Assessment Method (3D-CAM) or CAM-Intensive Care Unit. Secondary endpoints include a composite neurological outcome of POD and overt stroke, postoperative neurocognitive disorders, major morbidity and mortality. Associations between neurologic outcomes, neurobiomarkers and genetic variation will be explored.

    A total of 500 participants is required to achieve 90% power to find a statistically significant effect of the area under the curve MAP

    Ethics and dissemination

    Ethical approval has been obtained from all responsible ethics committees (Swiss lead ethics committee EKNZ 2022-01457 and Health Research Authority and Health and Care Research Wales, UK, REC 23/SW/0076). Results will be disseminated at national and international conferences and published in peer-reviewed journals.

    Workshops as a Research Method in Health Science: Epistemological and Methodological Perspectives

    ABSTRACT

    Aim

    The aim of this paper is twofold: (1) to introduce a phenomenological-hermeneutic approach and discuss its application within the context of WSs in the field of health science, (2) To present a method and a practical guide when conducting WSs in the field of health science.

    Design and Methods

    Epistemological and methodological discussions based on workshops as a self-standing research method.

    Results

    The epistemological and methodological discussions show that workshops conducted in health science are a self-standing research methods and align with a phenomenological-hermeneutical approach. Examples of research studies within this framework are provided to illustrate how workshops can be conducted in health science within this epistemological approach.

    Conclusion

    The phenomenological-hermeneutical approach embraces workshops as a research method as it includes individual experiences through self-reflection and shared contributions through interpretation. Furthermore, a systematic approach with regard to planning, conduction, data collection, and data analysis leads to reliable findings, enhancing the transparency of the research method and thus creating scientific knowledge. This paper argues that the systematic approach of “the how” to conduct workshops with “the why” enhances the transparency and trustworthiness of the research.

    Implications for the Profession

    Workshops are a way to involve and engage users in co-design processes that aim to develop solutions in clinical practice. User involvement has become an important part in academia and is essential in all aspects of the research process. However, we need solid systematic methods to create valid knowledge. Workshops are a self-standing research method, and a phenomenological-hermeneutical approach allows for an understanding of the phenomena as they unfold, emphasising subjective perceptions and meanings, which will finally lead to the development of a suitable solution for clinical practice.

    Impact

    This paper contributes theoretical knowledge about the use of workshops as a research method. It combines “the how” to conduct a workshop with “the why” and highlights the relevance of a phenomenological-hermeneutical approach. The main argument is that workshops are a self-standing research method; hence, this paper adds value in the academic field as it provides a scientific framework. The paper presents a method and a practical guide for researchers who plan to conduct workshops in the field of health science.

    Reporting Method

    No available EQUATOR guidelines were applicable to this methodological paper because no new data was created or analysed.

    Patient or Public Contribution

    This is a methodological paper, and thus, there was no direct patient or public involvement.

    Weight Bias Interventions for Healthcare Professionals: An Integrative Review

    ABSTRACT

    Aim

    To describe interventions to mitigate weight bias among practicing healthcare providers and examine their effectiveness.

    Design

    An integrative review.

    Methods

    The framework of Whittemore and Knafl (2005) was utilised to identify and synthesise studies of weight bias interventions. Covidence reference management software facilitated screening using predetermined eligibility criteria that is, published in peer-reviewed journals, reported in English, and described outcomes for weight bias mitigation interventions among healthcare providers with a professional practice licence. We evaluated study quality using Joanna Briggs Institute's Critical Appraisal Tools for qualitative and quantitative studies.

    Data Sources

    Five databases were searched (CINAHL, Embase, EBSCOhost, APA PsycINFO, and Scopus) in July 2024.

    Results

    Sixteen articles met the inclusion criteria. Four themes emerged: (1) active learning lessens weight bias more than passive learning, (2) multicomponent approaches yield better outcomes, (3) healthcare providers are willing to change their practices, and (4) explicit attitudes and beliefs are more amenable to change than implicit ones. Four sub-themes within theme one included the use of in-person workgroups; films, computer-based, and podcast delivery; written modules; and physical characteristic modifications, such as the use of an adiposity empathy suit. Intervention designs using a theory-based, active learning approach with repeated sessions were most successful at decreasing negative weight-biased attitudes and beliefs.

    Conclusions

    Interventions that effectively reduce weight bias among practicing healthcare providers vary, yet evidence suggests that weight bias mitigation is achievable. These interventions offer strategies to improve patient-centred care among patients living with obesity.

    Impact

    Healthcare providers often display weight bias. This review synthesises information on effective interventions for reducing bias, which may limit the subsequent negative patient outcomes associated with it.

    Reporting Method

    The Preferred Reporting Items for Systematic Reviews and Meta-Analyses was the structure used for this paper.

    Digital Intervention for Psychedelic Preparation (DIPP): protocol for a randomised controlled feasibility trial comparing meditation- and music-based programmes in healthy volunteers

    Por: McAlpine · R. · Jaglinska · M. · Jedlovszky · K. · Kuc · J. · Castro · A. · Piot · A. · Timmermann · C. · Skipper · J. I. · Sacchet · M. D. · Kamboj · S. K.
    Introduction

    Psychedelic-assisted therapy shows promise for treating various mental health conditions; however, its reliance on intensive psychological preparation limits its broader application. Digital health interventions have the potential to address this limitation by providing structured, accessible and scalable preparation solutions. This randomised controlled feasibility trial aims to evaluate the feasibility and preliminary efficacy of the Digital Intervention for Psychedelic Preparation (DIPP), a 21-day mobile-accessible programme designed to prepare individuals for psychedelic experiences.

    Methods and analysis

    The study will recruit 40 non-treatment-seeking adults without a clinical diagnosis, randomly assigning them to one of two conditions: (1) DIPP-MEDITATE, which combines daily guided meditation with background music or (2) DIPP-MUSIC, which provides the same background music without guided meditation. Both groups will complete the 21-day digital intervention remotely. Following the intervention, participants will attend an in-person supervised psilocybin session, receiving a standardised 25 mg dose. Primary outcomes focus on feasibility metrics including recruitment efficiency, participant retention and adherence to the intervention protocol. Secondary outcomes assess subjective feasibility, acceptability and preliminary efficacy, specifically evaluating psychedelic preparedness, the quality of the psychedelic experience and changes in wellbeing, with follow-up assessments at 2 weeks, and at 3, 6 and 9 months post-session. Exploratory measures include neuroimaging, physiological, cognitive and psychological assessments, as well as voice note experience sampling through a chatbot (referred to as ‘DIPP-bot’) to monitor inner speech, thought and emotional states during the intervention and follow-up periods.

    Ethics and dissemination

    Approved by UCL Research Ethics Committee (ID: 19113/003), this study follows the Declaration of Helsinki. Results will be published in peer-reviewed journals and presented at conferences. Confidentiality will be maintained throughout.

    Habitual coffee consumption poorly correlates with sleep quality and daytime sleepiness: A cross-sectional study

    by Simon Söderholm, Martin Ulander, Vanessa William Toma, Sara Kaufmann, Xiangyu Qiao, Daniel Berglind, Susanna Calling, Bledar Daka, Ludger Grote, Mats Martinell, Frida Bergman, Pontus Henriksson, Carl-Johan Östgren, Wen Zhong, Claudio Cantù, Fredrik Iredahl

    Coffee is the most common drink in the world, second only to water. This makes caffeine, the ingredient of coffee known for its wakefulness-promoting effects, one of the most used psychoactive substances. The psychoactive property of caffeine is well-characterized, and entails its interaction with the adenosine receptors, involved in sleep regulation. While studies have shown a deleterious immediate effect of caffeine on sleep, less is known about the effects of chronic caffeine exposure. In the present cross-sectional study, we investigated this relationship across a large cohort of 30,154 individuals participating in the Swedish Cardiopulmonary Bioimage Study (SCAPIS), which allowed us to compare habitual coffee intake with sleep habits, subjective estimate of daytime sleepiness, and underlying genetic variants. According to our analyses, different degrees of coffee consumption, confirmed by statistical association with previously reported genetic variants, showed very low association with estimated patterns of sleep habits or perceived daytime sleepiness. These results indicate that coffee may be less impactful on sleep habits than previously thought, or that other mechanisms, such as the adaptive capabilities of the adenosine system in adult coffee users, may dampen its psychoactive potency.

    Integrating care in a childrens hospital: a qualitative interview study with mental and physical health professionals in England

    Por: Morgan · T. · Pilimatalawwe · D. · Mannes · J. · Morse · I. · Folwell · J. · Hain · P. · Walsh · C. M. · OCurry · S. · Duschinsky · R.
    Objective

    To explore physical and mental health professionals' hopes and concerns around integrating their services in a colocated children’s hospital.

    Methods

    One-off semi-structured interviews were conducted with 31 participants (16 mental health and 15 physical health professionals). Participants were purposively sampled to ensure representation across each trust and professional background. Participants included allied health professionals, nurses, team managers, paediatricians, psychiatrists and psychologists.

    Results

    Staff described integration as both promising and ambiguous. While many welcomed the potential for improved collaboration and holistic care, others expressed uncertainty about what integration would entail. Six key themes were identified: (a) siloed and patchy beginnings, (b) one whole child, (c) day-to-day of colocation, (d) the integrated worker, (e) patients not in the same boat and (f) extending integration.

    Conclusions

    This novel analysis offers insights around the practical and emotional processes involved in integrating care systems. Staff valued the potential for holistic, child-centred care, improved collaboration and shared learning but expressed concerns around ambiguity, shifting professional identities and the practicalities of colocating services. These tensions underscore the need for clearer communication, relationship-building and support structures during service redesign. Our findings also support integrating wider community and social care systems and call for future research involving young people’s perspectives to ensure meaningful, inclusive integration.

    Introduction

    Individuals experiencing moderate to severe mental illness have low rates of workforce inclusion, with a consequence of high welfare dependency, affecting both societal costs and health. Individual Placement and Support (IPS) is an approach to supported employment where the goal is to help people obtain jobs on the open rather than sheltered labour markets. Despite multiple randomised controlled trials (RCTs) indicating that the IPS model enables employment better than treatment as usual, with widespread adoption in some jurisdictions, the broader impacts of this large-scale implementation on mental health, quality of life and social functioning remain unknown.

    Methods and analysis

    Between 2012 and 2019, Norway introduced IPS through both local and national government projects. This study assesses the social and economic benefits of the implementation of IPS using Norwegian registry data, focusing on 18–45-year-old people receiving specialist mental healthcare, and who did not have steady employment at treatment start. Instead of assessing IPS efficacy in an RCT design, we use a naturalistic study design, evaluating IPS effectiveness by comparing aggregate population-level outcomes over time between areas where IPS was not available.

    In work package (WP) 1, we mapped the availability and implementation of IPS across Norway. This involved analysing information on funding, resource and capacity levels to understand how IPS had been rolled out across the country. While completed, we include a description of WP1 here, as it informs WP2 and WP3. WP2 is an effectiveness evaluation investigating the population-level outcomes of implementing IPS, focusing on health, mortality, quality of life and social functioning. Finally, in WP3, we assess the financial implications of implementing IPS from a public purse perspective, synthesising data on resource use and costs of implementation with data from WP2.

    Overall, we will examine the societal effects of IPS implementation on employment, welfare dependency, mental healthcare use, emergency care visits, self-harm and suicide, general mortality, crime and victimisation. Emphasis will be on long-term outcomes, and we will model the economic consequences of IPS. This study aims to inform policy making and strategies for implementing IPS at scale.

    Ethics and dissemination

    This is an effectiveness study using registry data. The Regional Committee for Medical Research Ethics Northern Norway, REK North has approved the use of registry data without informed consent for this project (approval number 134553).

    The findings will be disseminated both in academic peer-reviewed journals, directly to informants in WP1, to the public through media and the project website, and at relevant conferences and seminars for specific relevant target groups.

    Objective

    Workplace disclosure of Lesbian, Gay, Bisexual, Transgender and Queer (LGBTQ+) identity by healthcare employees is an understudied area and existing reviews of LGBTQ+ disclosure in the healthcare sector focus on patient perspectives, overlooking the unique challenges that healthcare professionals encounter. The aim of this study was to conduct a systematic review and meta-synthesis of existing qualitative studies exploring disclosure experiences of LGBTQ+ healthcare employees.

    Method

    The literature search integrated current research from 2011 to March 2023 and focused on qualitative studies exploring disclosure experiences of LGBTQ+ healthcare professionals. Ovid served as the primary platform for literature searches, supplemented by forward and backward citation tracking and additional searches in academic databases such as Google Scholar and Scopus. The studies underwent quality evaluation using the Critical Appraisal Skills Programme 2022 checklist and were synthesised using thematic analysis.

    Results

    The findings revealed seven studies with five prominent themes: (1) risk associated with disclosure, (2) making the decision to disclose, (3) cost of non-disclosure, (4) cost of disclosure and (5) benefit of disclosure. Additionally, five critical factors of disclosure were identified: level, scope, time, elements and method. Finally, the risk–benefit analysis underscored the dilemma and balance between authenticity and conformity, largely influenced by pervasive heteronormativity, resulting in a significant mental toll.

    Conclusions

    The findings must be interpreted considering certain limitations, such as the lack of generalisability of studies. However, the findings emphasise the critical need for cultivating trusting and accepting healthcare work environments for LGBTQ+ staff.

    Introduction

    COVID-19 (Corona Virus Induced Disease-19) caused by the SARS-CoV-2 coronavirus can be a serious in pregnancy. Therefore, vaccination with modRNA vaccines was recommended depending on the immunity status for women of reproductive age and pregnant women since 2022. However, there are only preliminary data on transplacental transmission of the virus and modRNA from genetic vaccines so far.

    Methods

    The study population included 106 women who have given birth at the Department of Obstetrics and Gynecology, University Hospital of Würzburg during November 2020 to October 2022. In addition to medical data and vaccination history, immunohistochemical examination of the placenta was performed with antibodies against SARS-CoV-2 spike and nucleocapsid proteins. RNAscope in situ Hybridization was used to show RNA detection in positive placental tissues as a proof of concept.

    Results

    Altogether, 87% of participants received at least one vaccine dose against SARS-CoV-2 and 56 women (42 vaccinated, 14 not vaccinated) contracted COVID-19. In total, 31 placentas were found positive for the spike protein. Spike positive cells were predominantly Hofbauer cells and trophoblasts. In three cases of vaccinated and then infected woman, an additional nucleocapsid staining was detected, but there was no significant difference in staining pattern in correlation to the vaccine/COVID-19 status. Interestingly, we did not find viral RNA in the investigated samples, but we could show a positive in situ Hybridization of BNT162b2 and S-encoding mRNA-1273 in two individual samples.

    Discussion

    The spike protein of SARS-CoV-2 has been be detected in placental Hofbauer and Trophoblast cells as well as villous endothelia after infection and vaccination indicating a possible transplacental transfer or uptake. These findings may suggest a potential for transplacental transfer or cellular uptake; however, the extent, mechanisms, and clinical significance of this phenomenon remain to be fully understood.Clinical trial registration: DRKS00022506.

    Cross-sectional observational study evaluating social brain health in HIV using a research domain criteria-based approach: a protocol

    Por: Vance · D. E. · Brennan-Ing · M. · Lambert · C. C. · Hellemann · G. · Zeng · X. · Lee · J.
    Introduction

    Some people with HIV (PWH) experience brain changes that affect neurocognition, but little is known about how HIV impacts social cognition or related brain regions. Social cognition, the ability to perceive, understand and respond to social information, is important for maintaining relationships and quality of life. This article provides the protocol for the first comprehensive study examining social brain function in PWH and people without HIV (PWoH). With three aims, this study will: (1) examine neural circuits related to social cognition; (2) examine social cognitive performance across two social cognitive domains and (3) examine the role of social cognition in everyday social functioning.

    Methods and analysis

    Referred to as Social Brain Health Study in HIV Study, this cross-sectional study will enrol 105 PWH and 105 demographically matched PWoH aged 18–65 years. The study administers a comprehensive assessment battery across two visits within a 2-week period. Visit 1 includes behavioural measures of social cognition (Perceiving Social Cues and Understanding Others), neurocognition and social functioning (social network size and loneliness). Visit 2 involves functional MRI procedures with three social cognitive tasks designed to activate key brain regions (ie, fusiform face area, superior temporal gyrus, temporo-parietal junction, dorsal medial prefrontal cortex).

    Ethics and dissemination

    This study was funded by the National Institute of Mental Health (MH139613) and approved by the Institutional Review Board of the University of Alabama at Birmingham (IRB-300013394). Data collection is ongoing. The first results are expected to be submitted for publication in 2030. Findings of this study will be published in peer-reviewed journals and presented at local, national and international conferences as well as patient organisations such as AIDS service organisations and community talks.

    Population-based study of pharmacogenetics and pharmacokinetics in Southern African patients with multidrug-resistant tuberculosis (PoPG): a protocol for the Namibian cohort

    Background

    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.

    Methods

    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.

    Data analysis

    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.
