To develop a context-specific health technology assessment (HTA) framework tailored to the healthcare needs and system of Iran, to improve evidence-based decision-making, optimise resource allocation and support progress towards universal health coverage.
A mixed-methods Delphi consensus study conducted using a three-phase, sequential approach: document review, qualitative focus group discussions and Delphi consensus rounds. The study reporting follows the Accurate Consensus Reporting Document guideline to ensure transparent reporting of consensus methods.
A national-level study conducted in Iran’s healthcare system between January 2023 and March 2024, including perspectives from public and academic institutions, policy bodies and patient organisations.
The study involved 18 purposively selected stakeholders in three focus group discussions, including policymakers, healthcare professionals, researchers and patient representatives. Subsequently, 20 HTA experts participated in three iterative Delphi rounds to refine and reach consensus on the framework components.
Identification of core components and operational steps required to develop and implement a comprehensive HTA framework in Iran.
The final HTA framework includes nine core components: (1) establishing a national HTA body; (2) engaging stakeholders; (3) building capacity through training and research; (4) developing standard HTA methodologies; (5) implementing prioritisation and evaluation processes; (6) ensuring sustainable funding; (7) enhancing transparency and accountability; (8) promoting continuous improvement and (9) fostering innovation. Detailed operational steps and micro-activities were developed for each component. The framework achieved an 84% consensus among Delphi panellists, indicating strong agreement on its content and applicability.
This tailored HTA framework provides a structured roadmap to institutionalise evidence-based decision-making in Iran’s healthcare system. Its implementation can strengthen the efficiency, equity and sustainability of healthcare planning and policy. Pilot testing is recommended to assess feasibility and scalability, with potential to serve as a model for other low-income and middle-income countries.
Palliative care reduces caregiver burden, alleviates patient symptoms, and supports treatment decision-making. However, despite these benefits, there is limited evidence on the effectiveness of palliative care interventions for caregivers of individuals with advanced dementia.
To integrate and analyze data on the effectiveness of palliative care interventions in improving caregiver outcomes in order to ensure that both patients and caregivers receive the support necessary for optimal care experiences, quality of life management, and advanced care planning.
A systematic search was conducted of six databases to identify relevant studies published from database inception to 12 December 2024. Randomized controlled trials (RCTs) investigating palliative care interventions for caregivers of people with advanced dementia were included. Version 2 of the Cochrane Risk of Bias tool was used to assess the risk of bias in the methodology of each study. Standardized mean differences (SMDs) between each intervention and control group were calculated. A random-effects DerSimonian and Laird model was applied to generate pooled SMD estimates for each outcome and assess its heterogeneity. A leave-one-out sensitivity analysis was performed to ensure the stability of the pooled effect sizes.
Eight RCTs were included in the final analysis. Palliative care interventions appeared to reduce conflict in decision-making among caregivers of people with advanced dementia.
Palliative care interventions were successful in reducing conflict in decision-making of caregivers of people with advanced dementia. However, the modality's effects on caregiver satisfaction and caregiver distress need further investigation.
Future palliative care interventions for caregivers of advanced dementia patients should focus on developing the contents of palliative care materials based on evidence-based evaluations and explore strategies to improve engagement between patients, caregivers, and healthcare professionals.
About 30% of depressed patients suffer from a protracted course in which the disorder continues to cause significant burden despite treatment efforts. While originally developed for relapse prevention, mindfulness-based cognitive therapy (MBCT) has increasingly been investigated in depressed patients with such ‘difficult-to-treat’ courses. This is a protocol for an individual participant data (IPD) meta-analysis aiming to determine efficacy and potential moderators of MBCT treatment effects in this group based on evidence from randomised controlled trials.
Systematic searches in PubMed, Web of Science, Scopus, PsycINFO, EMBASE and the Cochrane Controlled Trials Register for randomised controlled trials were completed on 17 June 2024. Authors of identified studies have contributed IPD, and data extractions have been completed. An update search will be conducted immediately before the start of data analyses. We will investigate the following outcomes: (a) self-reported and observer-reported severity of depression symptomatology, (b) remission and (c) clinically meaningful improvement and deterioration. One-stage and two-stage IPD-MA will be conducted with one-stage models using the observed IPD from all studies simultaneously as the primary approach. One-stage IPD models will include stratified study intercepts and error terms as well as random effects to capture between-study heterogeneity. Moderator analyses will test treatment-covariate interactions for both individual patient-level and study-level characteristics.
The results will inform understanding of the use of MBCT in patients with current ‘difficult-to-treat’ depression and will contribute to arguments in favour of or against implementing MBCT as a treatment for this group. They will be published in a peer-reviewed journal and made available to stakeholders in accessible formats. No local ethical review was necessary following consultation with the Ethics and Governance Board of the University of Surrey. Guidance on patient data storage and management will be adhered to throughout.

To explore the barriers and facilitators in adherence to the guidelines in the management of benign paroxysmal positional vertigo from the perspective of primary care physicians.
Qualitative study using focus groups.
L’Hospitalet del Llobregat (Barcelona), Spain.
Qualitative study using focus groups. Structured 90 min focus groups were conducted until data saturation was reached. Each session included a moderator and an observer from the research team. Sessions were transcribed and thematically analysed by three independent researchers.
Purposeful sampling was used to form four groups of 4–10 participants, selected by sex, age, years of experience and primary care team (PCT). Participants were recruited between January and February 2023.
A total of 34 family physicians belonging to four PCTs participated in the study. The main barriers identified were a lack of time, negative initial experiences, a fear of harming patients (especially older adults), difficulty in nystagmus visualisation and challenges in managing patient expectations, as many preferred medication over physical manoeuvres. Facilitators included potential time savings from effective early management, the value of initial practical training with periodic refreshers, access to expert consultants for case discussions and the availability of digital tools, such as tutorials, videos and aids for nystagmus interpretation.
Health systems should invest in protected time for history-taking and physical examination, and in regular, updated training for primary care professionals. This could improve vertigo management and reduce unnecessary investigations and medications, ultimately benefiting both patients and the healthcare system.
To examine demographic, behavioural and clinical determinants of self-rated health (SRH) among Iranian adults with hypertension (HTN), with a particular focus on the association between blood pressure (BP) control and perceived health.
National cross-sectional analysis of 15 predictors spanning demographic, lifestyle and clinical domains.
2021 Iranian STEPwise Approach to Non-communicable Disease Risk Factor Surveillance, a nationally representative survey.
A total of 8812 adults with HTN (mean age 56.97 years; 57% female). Controlled HTN was defined as systolic blood pressure
The primary outcome was SRH, measured on a standard EuroQol-Visual Analogue Scale (0–100).
Controlled HTN was independently associated with higher SRH scores (β=1.31, 95% CI 0.07 to 2.54). Positive predictors of SRH included male gender (β=4.34, 95% CI 3.38 to 5.31), higher wealth (richest vs poorest: β=5.52, 95% CI 4.06 to 6.97), sufficient physical activity (β=4.38, 95% CI 3.48 to 5.28), healthier diet (β=3.06, 95% CI 1.99 to 4.14) and complementary insurance coverage (β=2.50, 95% CI 0.63 to 4.37). Significant negative predictors included diabetes mellitus (β=–4.23, 95% CI –5.59 to –3.26), dyslipidaemia (β=–3.61, 95% CI –4.62 to –2.59), people who smoke (β=–4.21, 95% CI –5.64 to –2.78) and older age. Notably, antihypertensive medication use showed one of the strongest negative associations with SRH (monotherapy: β=–4.83; combination therapy: β=–5.28), likely reflecting underlying disease severity and treatment burden.
Better SRH among hypertensive adults was associated with controlled BP, healthier lifestyle patterns and higher socioeconomic status. Conversely, comorbidities, smoking, older age and antihypertensive treatment were linked to poorer perceived health. Integrating SRH screening into HTN management may help identify vulnerable individuals and inform targeted interventions addressing behavioural and socioeconomic determinants of health.

Adolescent mental health and wellbeing are of growing concern globally with increased incidence of mental health disorders in young people. BrainWaves provides a framework for relevant and diverse research programmes into adolescent mental health and wellbeing that can translate into practice and policy. The research programme is a partnership with schools centred on establishing a large (n > 50,000) cohort and trials platform. Reported here is the BrainWaves cohort pilot study. This was designed as proof-of-concept for our recruitment and data capture pipelines, and for cost-modelling. A network of research schools was recruited and a computer-driven questionnaire administered. The eligible population was 16 + year olds who were attending the research schools. Of 41 research schools, 36 (88%) participated over one three-week and one four-week data collection period. From an eligible population of 33,531 young people, 16,010 (48%) attended the study lesson and created an account. Of the 16,010 (100%) who created an account, 15,444 (96%) consented to participate, 9,321 (60%) consented to linkage of research data with educational records, and 6,069 (39%) consented to linkage of research with school/college attendance data. Participants were aged 16–19 years, 59% female, and 76% White. Higher levels of anxiety and depression were found in females than males. Higher levels of media-based social networking were found in females, whereas higher levels of media-based gaming were found in males. Females were more likely to report insufficient sleep whilst males were more likely to report high levels of exercise. This study confirmed an ability to recruit at pace and scale. Whilst the response-rate does not indicate a representative sample, the demographics describe an inclusive and diverse sample. Data collected confirmed findings from previous studies indicating that the electronic data collection methods did not materially bias the findings. Initial cost-modelling suggests these data were collected for around £20 per participant.Tobacco use is the most significant modifiable risk factor for adverse health outcomes, and early research indicates there are also significant harms associated with vaping. National targets aim to reduce smoking and vaping during pregnancy for Aboriginal and Torres Strait Islander people. While most Aboriginal and Torres Strait Islander people want to quit, cessation is frequently attempted without support, increasing the chance of relapse. Group-based smoking cessation programmes increase quit success by 50%–130% in the general population; however, they have never been evaluated in Aboriginal and/or Torres Strait Islander communities.
The Gulibaa study is an Indigenous-led and community-embedded project that will co-design, implement and evaluate a group-based model of care to support Aboriginal and Torres Strait Islander women to be smoke- and vape-free. Staff of Health Services in New South Wales, Australia, will receive training to deliver a face-to-face group-based smoking and vaping cessation intervention. Aboriginal and/or Torres Strait Islander people who identify as a woman or non-binary, are pregnant or of reproductive age (16 to 49 years), currently smoke or vape at least once per day and are willing to attend the programme are eligible to participate. Up to 500 participants will be recruited. A mixed method evaluation approach will be implemented guided by the RE-AIM framework. Outcomes will include intervention reach, intervention effectiveness (determined primarily by self-reported 7-day point prevalence abstinence at 6 months follow-up), acceptability and feasibility of the intervention, programme fidelity and maintenance and cost effectiveness.
Embedding culturally safe support to quit during pregnancy can result in improved outcomes for both mother and child and immediately improve intergenerational health and well-being. Ethics approval has been provided by the Aboriginal Health and Medical Research Council and the University of Newcastle. Study findings will be disseminated to Aboriginal and Torres Strait Islander communities in ways that are meaningful to them, as well as through Aboriginal health services, key national bodies, relevant state and federal government departments.

Codes of ethics are, for many, important documents that define the key values and behaviours expected of healthcare professionals. They are also documents that have been widely criticised. These criticisms range from being vague to failing to provide guidance on many important issues. Codes, however, vary substantially in their scope, content and the guidance they provide.
This scoping review sought, in the context of comparative studies of codes, to examine the form (i.e., the structure of the code, its contents, principles or rules for example) and function (what the code says it does, either explicitly or implicitly) of codes, along with their points of con/divergence.
A systematic search was carried out using Scopus, PsycInfo, CINAHL and Medline.
Thirty-one papers met inclusion criteria and were included in this review. Results suggest that while there were a number of similarities seen across codes, there were also substantial points of divergence related to the content of codes and structure. These differences were seen across professions, countries and time, suggesting that culture, history, politics and perhaps even geography influence the content of codes.
These findings are discussed in light of the broader literature that examines and critiques codes.
To examine the direct and indirect predictors of thriving at work and its impact on intention to leave the organisation or profession among early career nurses.
A repeated cross-sectional design.
A sub-study of early career nurses as part of an Australian longitudinal follow up study, commenced in 2018, was conducted. The sub-study asked early career nurses between their second and sixth year after graduating to complete a structured online questionnaire assessing thriving at work and several predictor variables. Data were analysed using Pearson's correlation, multiple linear regression, and path analysis.
Among the 67 participants (response rate of 42.9%), thriving at work was positively correlated with occupational hardiness, social support from colleagues, and wellbeing, while negatively correlated with compassion fatigue. Thriving at work and perceived organisational support were the significant predictors of intention to leave the organisation, while perceived organisational support was the only significant predictor of intention to leave the profession.
The importance of strong collegial relationships, compassion fatigue, and improving wellbeing to enhance thriving at work are highlighted. Fostering an environment where employees can thrive is crucial to reduce the intentions to leave an organisation. Relationships with the managers and quality of care provision also play a crucial role in reducing turnover and leave intentions. Perceived organisational support enhances employee wellbeing, thereby reducing turnover intentions. Future strategies should focus on comprehensive support systems to retain nurses in their organisation and the profession.
Enhancing thriving at work and perceived organisational support can reduce early career nurses' intention to leave their organisation. However, job stressors and interpersonal conflicts also influence professional leave decisions.
This study has adhered to the STROBE guidelines.

Many amputees experience phantom limb pain (PLP). Pharmacological management is the mainstay of treatment, but effectiveness is limited, and it is associated with significant side effects. Sensory discrimination training (SDT) is a non-pharmacological treatment for PLP. Previously, SDT required a clinician, or carer, to administer it, creating a barrier to real world use. In this trial, an automated SDT device (SP1X, 2pd Ltd, Middlesbrough, United Kingdom) for the self-management of PLP will be investigated for efficacy.
The Phantom Relief is a decentralised, randomised, placebo-controlled, mixed-methods, superiority trial. Participants will take part from their own homes, using an electronic data capture tool to complete all trial documentation. Eligible, consenting individuals with PLP (intensity rated as ≥4 on a 0–10 scale; n=100) will be randomised to receive the SP1X device (intervention group) or a placebo device SP1X7 (placebo group). The first and second treatment sessions will be observed via video call to provide set-up guidance and any additional advice needed. The primary outcome measure will be the McGill Pain Questionnaire revised (SF-MPQ-2). Outcome measures will be collected at baseline, 3 weeks (immediately post intervention) and 3 months follow-up. Statistical analysis will be carried out by a blinded statistician (analysis of covariance model conditioning on the baseline and stratification factors). Semi-structured interviews will be carried out with a sub-sample (n=10–15) of intervention group participants. Participants will be provided with their allocated device for home use. Online video calls will be used to instruct participants on how to set up and use the device by the research assistant (RA). The RA will observe the first and second treatment sessions and provide any additional advice needed. Participants in both groups will be asked to use the device for 60 min/day for at least 15 days of the 21-day treatment period and to record device use in a study diary.
Approval has been obtained from Teesside University School of Health and Life Sciences Research and Ethics Committee, the North of Scotland Research Ethics Service, Health Research Authority, and a letter of no objection was obtained from the Medicines and Healthcare products Regulatory Authority. The results will be disseminated through peer-reviewed articles, conference presentations and a doctoral thesis.
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.
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.
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.

Microplastic pollution has become a global concern and understanding its impact on wildlife requires effective sampling techniques that quantify exposure. In particular, non-lethal sampling techniques are needed for passerines for which microplastic exposure is poorly understood. In this study, we evaluated whether non-lethal proventricular gastric lavage can provide a representative sample of total microplastic ingestion in passerine birds. We sampled Brown-headed Cowbirds (Molothrus ater) (n = 105) from Government Canyon State Natural Area in San Antonio, Texas, United States (US). We performed gastric lavage to recover microplastics from each bird, before euthanizing them and dissecting gastrointestinal tracts. We recovered microplastics from 99% of birds. Gastric lavage recovered an average of 50.4% of ingested microplastics although recovery rate was highly variable (range: 0–100%, coefficient of variation: 59.52%), indicating much uncertainty in estimating individual total microplastic loads from gastric lavage. Sampling date influenced microplastic loads and recovery rates, which may be due to untested microplastic-environment interactions or may be an artifact of sampling conditions. Recovery rate was unaffected by time of day, bird age, sex, or body condition, or microplastic shape. Overall, our findings suggest that gastric lavage provides highly variable estimates of total gastrointestinal microplastics, and may be more appropriate for studies of recently ingested microplastics, only, that should be contained within the proventriculus.by Ramtin Naderian, Sajjad Ahmad, Mojgan Rahmanian, Shahrzad Aghaamoo, Aryan Rahbar, Omid Pajand, Akram Alizadeh, Shahin Nazarian, Samira Sanami, Majid Eslami
Chandipura virus (CHPV) is endemic in India, with frequent outbreaks reported. No approved medicines or vaccines exist for CHPV. We aimed to develop a multi-epitope vaccine for CHPV using immunoinformatics approaches. In this study, a multi-epitope vaccine construct was developed by combining 11 CTL epitopes, 2 HTL epitopes, and 1 linear B-cell epitope from glycoprotein (G) with 1 EAAAK linker, 10 AAY linkers, 2 GPGPG linkers, 1 KK linker, and adjuvant (RS-09 peptide). We predicted and optimized the vaccine’s protein structure. Furthermore, the vaccine 3D structure was docked with Toll-like receptor 4 (TLR4) using the Cluspro 2.0 server, and the docked complex was analyzed using molecular dynamics (MD) simulation by the assisted model building with energy refinement (AMBER) v.20 package. The vaccine’s immune simulation profile was determined, and the vaccine sequence was reverse translated and in silico cloned into the pET28a (+). The vaccine’s population coverage was 99.79% across the worldwide. The vaccine was soluble, non-allergenic and non-toxic, with high levels of antigenicity. The quality of the vaccine’s 3D structure improved following refining, and the number of residues in the most favoured regions of the Ramachandran plot increased by 94.2%. The molecular docking, with a docking score of −1157 kcal/mol, and MD simulation results revealed a robust interaction and remarkable stability between the vaccine and TLR4. The immune response simulation indicated a decrease in antigen levels and an increase in interferon‐gamma (IFN‐γ) and interleukin-2 (IL-2) concentrations after each injection. In silico results indicate that this vaccine possesses significant promise against CHPV; however, laboratory and animal studies are necessary to validate our findings.Food insecurity is increasing in the UK, impacting choice and diet quality. The current means-tested free school meals (FSM) policy was put in place to address dietary inequalities and food insecurity in school children. In secondary schools, approximately 20% of students who are eligible and registered do not take their FSM. Working across a range of schools that have variable levels of FSM uptake, this study aims to evaluate the effectiveness and cost-effectiveness of the current means-tested FSM policy in UK secondary schools on diet and food insecurity outcomes, understand what factors are associated with uptake and test the potential impact of any proposed policy change.
Secondary schools (n=32) in both Northern Ireland and the Midlands region of the UK are being recruited into the study. Data will be collected from school staff, governors, students and parents via questionnaires, as well as observational data of school eating environments. Qualitative data will be collected in selected case study schools (n=6–8). Multilevel modelling will be undertaken to evaluate the association between FSM uptake and fruit and vegetable intake, overall diet quality and food insecurity in all students. Economic evaluation will be conducted using a cost–utility approach. The effect of policy change will be modelled and school factors associated with FSM uptake explored using multiple methods.
Ethical approval has been obtained from Queen’s University Belfast Faculty of Medicine, Health and Life Sciences Research Ethical Committee (MHLS 23_55). Findings will be disseminated to key national and local agencies, to schools through reports and presentations, and to the public through media and open access publications.
To identify facilitators and barriers and tailor implementation strategies to optimize emergency clinician's use of adult and paediatric sepsis pathways.
A qualitative descriptive study using focus group methodology.
Twenty-two emergency nurses and ten emergency medical officers from four Australian EDs participated in eight virtual focus groups. Participants were asked about their experiences using the New South Wales Clinical Excellence Commission adult and paediatric sepsis pathways using a semi-structured interview template. Facilitators and barriers to use of the sepsis pathways were categorized using the Theoretical Domains Framework. Tailored interventions were selected to address facilitators and barriers, and a re-implementation plan was devised guided by the Behaviour Change Wheel.
Thirty-two facilitators and 58 barriers were identified corresponding to 11 Theoretical Domains Framework domains. Tailored strategies were selected to optimize emergency clinicians' use of the sepsis pathways including refinement of existing education and training programmes, modifications to the electronic medical record system, introduction of an audit and feedback system, staffing strategies and additional resources.
The implementation of sepsis pathways in the Emergency Department setting is complex, impacted by a multitude of factors requiring tailored strategies to address facilitators and barriers and optimize uptake.
This study presents a theory-informed systematic approach to successfully implement and embed adult and paediatric sepsis pathways into clinical practice in the Emergency Department.
Optimizing uptake of sepsis pathways has the potential to improve sepsis recognition and management, subsequently improving the outcome of patients with sepsis.

To explore the key factors influencing nurses' capability, opportunity and motivation to offer the choice for self-collection for cervical screening within rural primary care services, following a national policy change in Australia.
A qualitative study informed by implementation and behavioural change frameworks.
Primary health nurses working in Victoria were invited to participate in semi-structured interviews via video or telephone between December 2022 and March 2023. Eighteen nurses from 18 clinics participated. Interview data were analysed following a Framework analysis approach, and themes were mapped to the COM-B model.
Nurses were highly motivated to offer the choice for self-collection due to perceived advantages for their patients and potential opportunities for reaching people hesitant to screen. There was variation in how nurses offered this choice, and to whom. Some nurses were concerned about lost opportunities to visualise the vulval area or cervix, or to have broader health and wellbeing conversations with patients. Views were mixed about how self-collection would impact nurse roles, and several external factors were impacting their opportunities as cervical screening providers.
Appropriately trained nurses have the capability and motivation to incorporate the choice for self-collection within their screening practice; however, their opportunity to maximise equity and increase participation is impacted by funding models and structures that limit their autonomy.
People living outside major cities experience greater healthcare inequities. Australia introduced access to the choice for self-collection for all eligible individuals in 2022, in part to achieve greater equity in the national screening program. Nurses can play a key role in program delivery. Understanding how they incorporate self-collection into their practice, and the key factors influencing implementation in rural primary care settings, can inform future program implementation and improve outcomes for patients.

In addition to hypertension, the constellation of metabolic abnormalities (diabetes mellitus, dyslipidaemia and/or obesity) independently increases the incidence and severity of cardiovascular diseases, and this is compounded by the modern lifestyle and ageing society. The prevalence of metabolic syndrome is high and non-hypertensive heart failure is common in Asians. Adverse cardiac remodelling is an important substrate for cardiac dysfunction in the onset and progression of heart failure and its amelioration improves outcomes and prognosis. A better understanding of metabolic-driven cardiac remodelling is warranted due to the rising prevalence and complexity of metabolic syndrome and strong interests in targeted therapy.
Response of the myocardium to hypertrophic conditions in the adult population is a prospective observational cohort study with an aim to establish the significance of cardiac remodelling by cardiovascular magnetic resonance (CMR). The current recruitment target is 2000 participants. Expanding from the initial population with hypertension, the study examines adults with cardiometabolic conditions, including diabetes, dyslipidaemia, obesity and fatty liver disease. Eligible patients are identified at National Heart Centre Singapore, primary care clinics and through public outreach. Physical, clinical, imaging and biochemical data are collected. Cardiac remodelling features pertaining to hypertrophy, fibrosis and functional changes are assessed on CMR. Body adiposity is mapped by MRI across the heart, liver and abdomen. Outcome data are adjudicated and follow-up assessment will be available in a subset of participants. Blood biomarkers will be investigated in relation to imaging findings. Cross-sectional analysis will establish the implication of cardiometabolic disease towards cardiac remodelling, while follow-up and outcome analysis will infer on disease progression and prognosis.
The study was approved by the SingHealth Centralised Institutional Review Board (2015/2603). Written informed consent is obtained from all participants. Study findings will be reported in peer-reviewed journals and at scientific conferences.

To examine whether manpower and expertise understaffing are distinct, and whether they relate similarly to nursing stressors, burnout, job satisfaction and intentions to turnover.
A cross-sectional survey of hospital nurses nested within units was used.
The sample included 402 nurses. Nurses provided ratings of the study's variables using validated self-report measures. The data were analysed both as multilevel and single-level data.
Manpower and expertise understaffing contributed unique explained variance to all of the examined outcomes. Nurses within the same units experience different understaffing levels. Expertise understaffing emerged as a significantly stronger predictor than manpower understaffing for three of the six of the outcome variables (illegitimate tasks, job satisfaction and turnover intentions).
Manpower and expertise understaffing are distinct, and both are associated with nurse outcomes.
We have adhered to the STROBE guideline for cross-sectional studies.
Considering both manpower and expertise understaffing to maintain proper staffing levels in nursing units is crucial.

The resources are also linked on national and international clinical and charity platforms.
Youth Med.Info addresses a gap in accessible, accurate mental health medicines-information by placing users – children, young people, parents/guardians and clinicians—at the centre of its design.
Adolescence and youth are periods of significant maturational changes, which seem to involve greater susceptibility to disruptive events in the brain, such as binge drinking (BD). This pattern—characterised by repeated episodes of alcohol intoxication—is of particular concern, as it has been associated with significant alterations in the developing brain. Recent evidence indicates that alcohol may also induce changes in gut microbiota composition and that such disturbances can lead to impairments in both brain function and behaviour. Moreover, there is evidence suggesting that microbiota-targeted interventions (psychobiotics) may help mitigate alcohol-induced damage in individuals with chronic alcohol use, positively influencing cognitive and brain functioning. However, the triadic relationship between BD, gut microbiota and brain structure/function, as well as the therapeutic potential of gut microbiota-targeted interventions in young binge drinkers, remains largely unexplored.
This double-blind, parallel, randomised controlled study aims to evaluate whether a BD pattern disrupts gut microbiota diversity in young college students (primary outcome). Additionally, it seeks to determine whether alcohol-induced alterations in the microbial composition and function are associated with immunological, cognitive, neurostructural and neurofunctional impairments (secondary outcomes). A total of 82 college students (36 non/low drinkers and 46 binge drinkers (BDs)), matched for age and sex, will be recruited from the University of Minho (Portugal). During the pre-intervention phase, all participants will undergo a comprehensive assessment protocol, including gut microbiota profiling, measurement of inflammatory markers, neuropsychological testing and structural and functional MRI. BDs will then be randomly assigned to a 6-week intervention with either a prebiotic (inulin) or a placebo (maltodextrin). Post-intervention assessment will mirror the baseline protocol, and craving and alcohol use will be monitored for 3 months.
The present protocol was approved by the Ethics Committee for Social and Human Sciences of the University of Minho (CEICSH 078/2022), ensuring compliance with national and international ethical guidelines, including the Declaration of Helsinki. Participation is voluntary and preceded by informed consent, with confidentiality and data processing safeguarded in accordance with the General Data Protection Regulation. All procedures are safe and non-invasive, and the prebiotics used are recognised as food ingredients in Europe, hold Generally Recognized as Safe status in the USA and are classified as dietary fibres by the Food and Drug Administration. Findings will be disseminated in national and international scientific forums, with preference for publication in open-access, peer-reviewed journals.
