The chemical composition of the venom in social Hymenoptera differs between castes and ages. Biogenic amines are contained in the venom of honey bees and may be physiologically effective to vertebrate predators and insects. This study quantified the concentrations of biogenic amines in venom and compared them between different castes and ages of honey bees. The concentrations of dopamine and N-acetyldopamine in venom were significantly higher in virgin queens than workers of the same age. The concentrations of dopamine, norepinephrine, tyramine and serotonin increased with age in virgin queens and workers. There was a significant positive correlation between venom dopamine concentrations and ovarian development in queenless workers, suggesting that the concentration of dopamine in the venom transformed from normal workers to reproductive females as that in virgin queens. We also tested the possibility of dietary effects on the concentration of dopamine in venom. Workers fed tyrosine or royal jelly showed significantly higher concentrations of dopamine precursors, tyrosine, 3,4-dihydroxyphenylalanine (DOPA) and dopamine in the hemolymph, as well as higher concentrations of dopamine in venom than in controlled workers. These results suggest that compositions of biogenic amines in venom are influenced by nutrition and change based on their social roles in honey bee society.by Michele Letitia Tchabou Tientcheu, Pierre Marie Kaktcham, Edith Marius Foko Kouam, Laverdure Tchamani Piame, Lysette Chabrone Djodjeu Kamega, Aarzoo , Agnihotri Shekhar, Singh Bhim Pratap, François Zambou Ngoufack
Conventional culture media such as de Man, Rogosa and Sharpe are essential for the growth of lactic acid bacteria and the production of metabolites used in the food and pharmaceutical industries. However, their high cost limits their application, particularly in low and middle-income countries. This study aimed to develop a cost-effective and efficient culture medium based on agro-industrial and environmental by-products, pineapple peels, sugarcane molasses, and black soldier fly larvae cake. After physico-chemical analysis of the by-products, excluding sugarcane molasses, a statistical mixture design was used to determine the optimal proportions for supporting lactic acid bacteria growth and bacteriocin production. Growth and metabolite production were monitored via plate count and agar well diffusion assays respectively. The strains tested belonged to the genera Lactobacillus, Bifidobacterium, Streptococcus, Lactococcus, and Bacillus as an out taxa group. The larvae cake showed high protein (48.47 ± 0.14%) and amino acid (17 types) content, while pineapple peels and molasses were rich in carbohydrates (89.52 ± 0.16% and 86.86 ± 0.07%). Based on regression models, the compromise formulation was defined as 55.15% larvae cake hydrolysate, 19.85% pineapple peel hydrolysate, and 25.00% sugarcane molasses. This medium highly supported lactic acid bacteria growth (9.43–9.86 log CFU/mL) compared to MRS and M17 (9.20–9.69 log CFU/mL), with Lactobacillus strains performing better. It also supported bacteriocin activity (11.0–14.5 mm inhibition zones), higher or similar to MRS and M17, with Lactococcus lactis subsp. lactis MA2 exhibiting the strongest effect. These results highlight the potential of this formulation as a sustainable, low-cost alternative for microbiology and biotechnology, particularly in resource-limited settings. The determination of its formula will allow its manufacture once the proximate compositions of the ingredients are known, regardless their origin. Future investigations will focus on optimisation of culture conditions, powder form formulation, and cost evaluation.To examine how cultural health brokers, as trusted intermediaries between formal systems and diverse ethnocultural communities, help navigate decisional conflict and misinformation regarding COVID-19 vaccination and to identify how their work contributes to system resilience in crisis contexts.
A community-based participatory action sensemaking research project to capture the real-time work of cultural health brokers in helping people navigate decisional conflict for vaccination.
Multicultural Health Broker Cooperative in Edmonton, Alberta where brokers speak 54 languages and serve more than 10 000 people from diverse ethnolinguistic communities. 28 cultural health brokers (9 male; experience 4–25 years) contributed to data collection and analysis between 16 September 2021 and 16 December 2021.
The brokers captured real-time reflections and self-interpretations in the SenseMaker platform through a theoretically informed, codesigned, mixed-method data collection tool. The team engaged in 13 weekly, 90 minute, audio-recorded and transcribed sessions: seven focused on understanding and action planning and five reflecting on the SenseMaker data, the focus of the thematic analysis. Data were managed in NVivo (QSR International, Version 12, 2018).
Brokers collected 277 narratives and conducted 13 sensemaking sessions. Understanding and purpose were identified in 68% of narratives as key to achieving coherence; 81% of narratives highlighted trust as crucial to what was needed for action; 62% of narratives reflected on a potential risk, with loss of trust a concern in 70% of them. A rich understanding of the sources of decisional conflict and misinformation was achieved and managed through outreach. There were four entwined components to navigation of the evolving complexity of COVID-19 vaccination: (1) building and sustaining trust; (2) strengthening relationships; (3) creating safe spaces for collective sensemaking and solution finding; and (4) leveraging cultural and social capital to address barriers. Through these mechanisms, brokers reduced decisional conflict and misinformation, supporting informed, values-congruent decisions.
Cultural health brokers, embedded within communities and linked to formal systems, play a critical role in crisis response by fostering trust, mobilising resources and enabling collective sensemaking. This study demonstrates how these intermediaries’ contextually and culturally attuned work provides a model for building system resilience for future crisis response.
Hospital patients are at an increased risk of falls, which are a significant safety concern within healthcare settings.1 Understanding how the COVID-19 pandemic has influenced fall risks is essential for identifying key factors that could inform future fall prevention strategies.2 This scoping review aims to explore the barriers and challenges associated with preventing inpatient falls in the context of the post-COVID-19 environment.
The methodology for this scoping review follows the framework established by Arksey and O’Malley. A comprehensive literature search will be conducted using specific keywords to identify relevant published studies. Searches will be performed across selected electronic databases, including PubMed/MEDLINE, CINAHL, Scopus, ProQuest and Web of Science, covering publications from 2014 to 2024. This review will focus on a global perspective. Two authors will independently screen titles and abstracts to identify potential studies for inclusion. Studies meeting the inclusion criteria will be retrieved for full-text review, and their references will be assessed for relevance using the same criteria. The PRISMA flow diagram will guide the review process. Data will be extracted, analysed and charted according to categories from the selected publications.
This scoping review will provide a comprehensive overview of the barriers and challenges in preventing inpatient falls in the post-pandemic context. The findings will be disseminated through submission for publication in a scientific journal.

The growing complexity of global health issues underscores the need for a skilled workforce, achievable through competency-based training (competency-based curricula, CBC) that integrates knowledge and practice. Starting from 2022, medical and nursing CBC were harmonised across universities in Tanzania to ensure all graduates attain nationally defined core competencies. The reform aligned programme structure, learning outcomes and assessment methods to promote consistency and interprofessional collaboration. However, questions remain about whether harmonisation alone can ensure the development of practical clinical competencies among students. This study explored the experiences of medical and nursing faculty and students in implementing clinical training as a component of CBC in two health training institutions in Tanzania.
An exploratory qualitative case study was conducted with 67 participants, using 8 in-depth interviews with administrators and 8 focus group discussions with faculty and students. Data were analysed using Braun and Clarke’s thematic approach.
Two private, faith-based medical universities in the United Republic of Tanzania.
The study purposefully recruited a total of 67 participants. The participants included university administrators (including Deputy Vice Chancellors for Academics, quality assurance officers and deans), medical and nursing faculty and students (fourth-year medical and third-year nursing students).
Two main themes emerged: challenges in implementing clinical training and strategies used to enforce clinical training. Key challenges included curriculum design gaps, inadequate faculty and clinical instructors, a large number of students and a shortage of hospital staff. Strategies used were utilisation of clinical skills and simulation laboratories, involvement of non-academic clinical specialists’ staff, use of student-centred learning methodologies and leveraging regional, district and specialised private hospitals for clinical teaching.
Despite notable challenges in clinical training, the institutions in this study have implemented proactive strategies to support clinical training. Based on the findings, stakeholders should invest in increasing faculty and clinical instructors and expanding clinical placements to regional, district and private hospitals.
Falls are highly prevalent among individuals with dementia, largely due to the cognitive and physical impairments associated with the condition. Understanding the barriers and challenges to fall prevention in community-dwelling individuals with dementia is essential for developing tailored strategies that address their unique risks. Despite the existing evidence on fall prevention in older adults, few reviews specifically examine the obstacles faced by persons with dementia and their caregivers in community settings. This scoping review, therefore, aims to map the barriers and challenges to preventing falls among community-dwelling individuals with dementia.
This review will follow Arksey and O’Malley’s five-stage framework and be reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses—Extension for Scoping Reviews checklist. Six electronic databases (PsycINFO, PubMed, Web of Science, Cumulative Index to Nursing and Allied Health Literature, Scopus and Embase) will be searched for relevant studies published between 2014 and 2024. Grey literature sources, including dissertations and conference proceedings, will also be included. Data will be charted and synthesised thematically to provide an overview of barriers and contextual factors influencing fall prevention. The study commenced in August 2025 and is expected to be completed by February 2026.
As this review involves the analysis of existing literature, ethical approval is not required. Findings will be disseminated through peer-reviewed publications, conference presentations and summaries tailored for healthcare providers and caregiver groups.

This study aims to review case reports/series on West Nile virus (WNV) infection-associated cranial nerve (CN) neuropathy to explore the associated patterns and characteristics.
A systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria.
We reviewed the literature in PubMed/Medline, Google Scholar and ScienceDirect databases to retrieve relevant case reports.
Case reports published in the past 25 years on CN neuropathy in WNV-infected patients, with no language or geographic restrictions.
Retrieved data included patient demographics, disease presentation and treatment outcomes. Descriptive statistical analyses were performed to describe frequency and characteristics of CN neuropathies. Cross tabulation was performed to calculate statistical significance of association between patient characteristics, disease factors and treatment outcomes. Risk of bias was assessed using the JBI Critical Appraisal Tool for case reports.
A total of 30 case reports satisfied inclusion criteria. These studies described 42 cases that developed CN neuropathies as an outcome of WNV infection. Patients were in the main males (54.8%) and had a mean age of 52.5±15.5 years. The most frequently affected CNs were, in descending order, optic (n=21, 50.0%), facial (n=14, 33.3%) and abducent nerves (n=8, 19.0%). Age was significantly associated with optic nerve neuropathy (≥51 years) and facial palsy (
CN neuropathy represents an important subset of neuroinvasive disease caused by WNV. There is a slight male preponderance among the patient population who are mostly middle aged. Optic and facial nerves are mostly affected. Most patients show complete recovery, particularly in the absence of chronic diseases. The role of systemic antivirals in improving disease outcomes should be further investigated. Early detection of CN neuropathies is recommended by routine CN screening and use of specific tools such as MRI and neurophysiological tests.

BackgroundUpper extremity (UE) dominance is often defined by self-reported hand preference; however, this may not accurately reflect true functional or strength-based dominance. This study examined the relationship between writing hand, throwing hand, and maximal grip strength to assess how these measures align.
MethodsThirty-four healthy, recreationally active college-aged individuals reported their preferred writing and throwing hands and completed standardized grip strength testing. Associations among the variables were analyzed using Phi coefficients and chi-square tests.
ResultsA moderate, significant relationship was found between writing and throwing hand preference (φ = 0.456; p = 0.008), indicating general consistency across these subjective measures. However, no significant association emerged between grip strength dominance and either writing (φ = 0.027; p = 0.876) or throwing hand (φ = 0.096; p = 0.574).
ConclusionThese results suggest that grip strength dominance may not correlate with commonly used indicators of hand preference, highlighting the need for task-specific definitions of dominance in clinical and athletic contexts. Consequently, employing such task-specific definitions allows for more accurate assessments and enhances the translational relevance of research findings in practical settings.
To examine state-level variation in mental health screening practices for high school athletes in the USA and evaluate associations between screening protocols and adolescent depression-related and suicide-related outcomes.
Cross-sectional study of preparticipation examination (PPE) forms and Youth Risk Behaviour Surveillance System (YRBSS) data.
High school athletics across all 50 US states and the District of Columbia.
732 676 high school students who completed the 2021 YRBSS survey (grades 9–12).
Prevalence of depressive symptoms and suicide-related behaviours, measured using YRBSS items on sadness/hopelessness, suicide ideation, planning, attempts and suicide attempts resulting in injury. State-level PPE forms were reviewed for presence and depth of mental health screening, including Patient Health Questionnaire-4 (PHQ-4) and eating disorder (ED) risk questions.
Screening practices varied widely, ranging from no mention of mental health in some states to required evaluations with formal referral protocols in others. Of 732 676 students, 503 861 (68.7%) reported feeling sad or hopeless, 608 416 (83.0%) seriously considered suicide and 64 072 (8.8%) attempted suicide in the past year. States with required screening protocols had higher reported rates of depressive symptoms (71.0% vs 68.7%, p
High school athletes represent a vulnerable group in need of structured and standardised mental health screening. State-level screening policies were associated with lower suicide attempt rates, though causal inference is limited by the cross-sectional design. Standardised use of validated mental health tools may support early identification and intervention for at-risk adolescents.

BackgroundCapacity for elective general surgical care is an important reflection of a health system’s ability to meet a population’s surgical needs and is currently known to be inadequate in many low- and middle-income countries. Patient agency is a key, understudied factor which shapes how and when patients ultimately decide to engage with formal care. Understanding factors which influence patient care seeking activity can have important implications for how current and future health systems may be utilized. This study aims to explore how patients approach the navigation and triage of their elective hernia condition within the Kenyan surgical care system.
MethodsWe conducted a qualitative study of 38 convenience-sampled patients diagnosed with an elective hernia condition at a tertiary referral hospital in Kenya between November 2023 and March 2024. We utilized Braun and Clarke’s six-step model of thematic analysis to generate key themes across the phases of care seeking, reaching and receiving as modeled in the Three Delays Framework.
ResultsWe identified three main cross-cutting themes including (1) the flow of power from patients to providers, and vice versa, take the form of consent or knowledge, respectively; (2) trust is a limited currency required for patients to engage with formal care; and (3) internal and external contextual factors remain the foundation for patient-provider care activities. We incorporated these themes together in a framework which illustrates the cyclical nature by which each factor feeds back on the others, ultimately affecting patient care.
ConclusionsFluctuating flows of patient power and trust interacts with existing infrastructural context to influence the ability of a health system to generate care. Recognizing the interaction of these key factors may have important bearing on the successful implementation of any larger systemic efforts or policies to improve access to elective surgical care.
Overuse of CT scans is associated with multiple harms, such as an increased risk of cancer development, particularly in children. However, the rate of CT scan use is high and unwarranted worldwide.
This study aimed to identify the patterns and reported indications for head CT scans ordered for non-traumatic paediatric cases in Palestine.
This was a retrospective, cross-sectional study based on a desk review.
The study was carried out from June 2024 to September 2024 in five hospitals located in five major Palestinian governorates in the West Bank.
The study included records of children aged 14 or younger, presenting with non-traumatic complaints and having undergone head CT between January 2020 and September 2024. A total of 3715 patient records were explored, of which 2977 were included in the final analysis; 1764 (59.3%) males and 1213 (40.7%) females.
A pilot review of 100 records was conducted, and the data collection spreadsheet included demographic and clinical characteristics, presentations, reported reasons for CT requests, CT results, and information on lumbar puncture (LP) performance.
The mean age of patients was 4.3 years (SD±3.3), with 59.3% aged 3 to 11 years, and 47.7% presenting to hospitals in northern governorates. The most commonly reported presentation was fever and convulsion (8.2%), followed by convulsions (7.7%), and a combination of fever, headache and vomiting (6.5%). Only 12.9% of the CT scans yielded positive findings, including dilated ventricles (19.3%), sinusitis (18.8%), brain oedema (12.9%), and brain mass (11.1%). Most CT scans were requested to check for contraindications to LP, with only 4.1% having a positive CT finding indicating a contraindication. At the multivariate level, a positive CT result was associated with being a neonate, having a past medical condition, ordering CT to check for contraindication to LP and presenting with convulsions.
CT scans were found to be overused without justification, particularly for ruling out contraindications to LP. The development of clear and specific national guidelines is recommended. This process can be supported through training, decision support tools, alternative management pathways and specialist consultations to ensure compliance. Additionally, enhancing reporting quality and using health information systems are vital for monitoring and improving radiological safety.
Detecting cancer earlier improves treatment options and long-term survival. A multicancer early detection test that reliably picks up early-stage cancer would potentially save lives and reduce the cost of treating cancer. One promising candidate is the Enlighten test, which applies machine learning to plasma amino acid concentrations to detect cancer. In a cohort of 77 patients recently diagnosed with breast, colorectal, pancreatic or prostate cancer, 60 (78%) were detected by the test (sensitivity), with no false positives in 20 healthy controls. The MODERNISED study will further develop the Enlighten test to detect 10 different cancers by adding bladder, lung, melanoma, oesophageal, ovarian and renal cancer to the test.
MODERNISED (ISRCTN17299125) is a multicentre prospective, non-interventional, case–control study. We aim to recruit 1000 adult participants with a recent cancer diagnosis, 250 adult participants with symptoms of cancer where a cancer diagnosis was ruled out by the National Health Service (NHS) standard of care and 100 healthy adult volunteers. Cancer tissue of origin (ToO) will include bladder, breast, colorectal, lung, melanoma, oesophageal, ovarian, pancreatic, prostate and renal. Participants in the two non-cancer cohorts who are later diagnosed with cancer will be moved to the cancer cases cohort. The primary aim is to train and validate a machine learning algorithm to detect cancer, which will be evaluated by AUROC. Secondary aims include training and validating an algorithm to predict ToO and stage of cancer, exploring differences in performance by demographics and estimating how sensitivity varies across specificity cut-offs of 95%, 99% and 99.9%. These results will provide a statistically powered estimate of how well the Enlighten test can discriminate between individuals with and without cancer, which can then be validated for clinical use in further research.
This study is sponsored by University Hospital Southampton NHS Foundation Trust and has been approved by the Health Research Authority and Health and Care Research West Midlands (24/WM/0234). Results will be presented at scientific meetings and published in international peer-reviewed journals. Lay summaries of study progress and findings will be published on the Southampton Clinical Trial Unit’s website.
Oral health research provides evidence for policy and practice, yet no study has comprehensively mapped the scope of oral health research in Malaysia. The COVID-19 pandemic has also created a great impact on oral healthcare in Malaysia, including the dental care delivery. Additionally, there is a notable lack of research focusing on oral health during and after the COVID-19 pandemic. Therefore, this scoping review will aim to map the landscape of oral health research conducted in Malaysia and identify key topics, study designs, populations studied and gaps in the literature, in order to inform future research priorities and policy, particularly in the post-COVID-19 era.
The methodology draws on Arksey and O’Malleys’ seminal framework for the scoping review and will be reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Review (PRISMA-ScR) guidelines. We will search five major electronic databases—PubMed, Scopus, ProQuest, Cochrane and Web of Science—as well as selected grey literature sources (eg, theses, dissertations and conference proceedings) for studies published in English from January 2014 to December 2024. Studies of any design related to oral health in Malaysia will be included. Two reviewers will be performing title and abstract screening, in which they will be working independently. The included publication will undergo a full-text review, and references cited in these studies will be examined following the inclusion criteria. The PRISMA-ScR flow diagram will be used as a guide throughout the process. Data will be extracted, analysed and charted according to key categories identified in the included publications. A narrative synthesis and descriptive statistics will be presented.
The results of this scoping review will illustrate an overview and provide a better understanding regarding the oral health research in the Malaysian context; whether research has already been conducted, is currently ongoing and is still needed; and which areas should be prioritised for future investigation. As this review will use publicly available literature, formal ethics approval will not be required. The findings will be submitted for publication in an open-access peer-reviewed journal, presented at national and regional conferences and shared with Malaysian dental professional bodies and relevant stakeholders.

This study compared the effectiveness of first-time use of faster aspart with rapid-acting insulin analogues in patients with type 1 diabetes (T1D) or type 2 diabetes (T2D).
This retrospective cohort study used data from 1 January 2017 to 8 May 2021 captured in the Clinical Practice Research Datalink Aurum database in the UK.
Patients with T1D or T2D either initiating faster aspart or another rapid-acting insulin analogue (‘new users’) or switching from a rapid-acting insulin analogue to faster aspart or to another rapid-acting insulin analogue (‘switchers’) were included. The index date was the date of first prescription of faster aspart or a rapid-acting insulin analogue, or of switching to a different rapid-acting analogue or to faster aspart.
A total of 9695 and 2170 patients were included in the new users (T1D, 1737; T2D, 7958) and switchers cohorts (T1D, 1764; T2D, 406), respectively.
Glycated haemoglobin (HbA1c) change at 6 months, occurrence of hypoglycaemia from index to 12 months post-index and treatment persistency from index to discontinuation or censoring.
Numerically greater reductions were observed with faster aspart than rapid-acting insulins in T1D switchers and new users in change in HbA1c at 6 months. Patients with T1D who switched to faster aspart experienced a significant reduction in rate of hypoglycaemia (p=0.0021). Treatment persistency was higher with faster aspart than with rapid-acting insulins among T1D switchers. No distinction in treatment persistency was observed between the treatment groups for T1D new users or T2D switchers.
Reductions in HbA1c were numerically larger with faster aspart in three of four subgroups. There was higher treatment persistency with faster aspart vs rapid-acting insulin analogues among T1D switchers.

To clarify the concept of quiet quitting in nursing practice.
Concept analysis using Walker and Avant's concept analysis methodology.
The eight-step method by Walker and Avant guided the concept analysis.
A systematic literature search was conducted in CINAHL, PsycINFO, Scopus and MEDLINE without date restrictions, identifying 36 empirical and theoretical articles published in English.
Quiet quitting in nursing is defined by four key attributes: minimal compliance with job expectations, psychological and emotional detachment, withdrawal of discretionary effort and lingering in role despite dissatisfaction. Antecedents include unhealthy work environments, psychosocial strain (e.g., burnout, moral distress) and individual/demographic influences (e.g., age, coping strategies). Consequences include impaired team dynamics, reduced care quality and organisational decline and increased turnover intentions. Twenty-five studies used validated measurement tools, notably the Quiet Quitting Scale.
Quiet quitting is a subtle form of disengagement distinct from burnout and turnover. It reflects an adaptive coping response to sustained dissatisfaction and unmet expectations. It is both widespread and underrecognized, with implications for healthcare sustainability.
Understanding and addressing quiet quitting is essential for safeguarding professional standards, promoting nurse engagement and ensuring high-quality patient care. Early identification and systemic reforms are critical to mitigating its impact.
This study addresses the emerging challenge of nurse quit quitting. Findings can inform leadership, education and policy development globally, particularly in healthcare settings facing workforce strain, moral distress and retention challenges.

IntroductionOlder people in low- and middle-income countries face significant challenges when accessing primary care services. In Lebanon, most older people (75%) living with at least one chronic disease previously accessed private health services for care. However, the economic crisis substantially increased their reliance on primary healthcare centers (PHCCs), while factors shaping access to public services were unknown. This study explores the barriers and enablers influencing access to PHCCs’ services.
MethodsThis descriptive qualitative study involved 57 people including older adults (aged 60–92 years), informal caregivers, and service providers, recruited using maximum variation sampling. Data were collected through seven focus groups and fifteen interviews. The Framework Method was adopted for thematic analysis. The Patient-centered Access to Healthcare Framework facilitated mapping of barriers and enablers across five access opportunities.
ResultsFindings are presented under five themes: 1) perception of healthcare needs, enabled by acute symptoms, free services, literacy, and familial support but hindered by lack of information on services; 2) healthcare seeking, supported by respectful providers, familial support, available quality services, and positive leadership, but constrained by providers’ attitudes, poor service organization, limited finances, and negative perceptions; 3) healthcare reaching, enabled by proximity of PHCCs and home care, but limited by transport issues, mobility restrictions, staff and resource shortages, and service delivery challenges; 4) healthcare utilization, facilitated by low fees and economic recession, but hindered by lack of funds and financial resources; and 5) healthcare consequences, facilitated through positive relationships, literacy, and personal abilities, but constrained by cognitive and sensory limitations, poor relationships, and lack of care continuity, coordination, comprehensiveness, and patient-centeredness.
ConclusionsThis study highlights the challenges for older people, indicating factors to be strengthened and barriers requiring action at the PHCC and multi-sectoral levels. Ensuring adequate funding, information, and health coverage is primordial to improve older people’s access to PHCCs.
To uncover perspectives and refine 12 initial program theories concerning the implementation of pain management interventions in intensive care units. Contexts enabling implementation are delineated, and causal mechanisms within these contexts are described.
A realist evaluation approach was employed.
Fourteen purposively selected Australian nurses of variant roles were virtually and individually interviewed between July and September 2023. Participants were presented with initial program theory, and their perspectives were collated. Data were analysed using an integrated approach of context (C), mechanism (M), outcome (O) categorisation coding, CMO configurations connecting and pattern matching.
Pain management interventions work if perceived to be beneficial, precise, comprehensive and fit for purpose. Nurses should be willing to change attitudes and update knowledge. Unit leaders should nurture the development of nurses' professional identity, access to learning, autonomy and self-determination. Organisations should change the infrastructure, provide resources, mitigate barriers, develop shared mental models, update evidence and institute quality assurance. Adherence to interventions is affected by the outcomes of implementation and intrinsic merits of interventions. In these contexts, confidence is boosted; feelings of empowerment, self-efficacy, reflective motivation, trust, awareness and autonomy are developed; and capacity is built. Furthermore, frustration from the variability of practices is reduced, accountability and ownership are augmented, yielding positive implementation outcomes.
Findings have implications on nurses, team leaders and organisations concerned with implementation.
The findings provided a fortified understanding of conditions favouring successful implementation of pain management interventions. Actions should be undertaken at an individual, unit and organisation level to ensure successful implementation.

IntroductionObesity is a significant health issue associated with chronic conditions such as cardiovascular disease and type 2 diabetes. Bariatric surgery is the most effective weight loss treatment for obesity. This systematic review aimed to examine factors influencing individuals’ decisions to undergo bariatric surgery.
MethodsThis systematic review was guided by the JBI Manual for Evidence Synthesis for Qualitative Reviews and reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. Literature searches were conducted in CINAHL, PubMed, Cochrane Library, APA PsycINFO, and APA PsycArticles. Results were analysed using a meta-aggregative approach. Quality appraisal was conducted using the JBI Checklist for Qualitative Research.
ResultsThirteen studies were included. Health concerns, fears of obesity-related comorbidities, and a desire to improve physical health and quality of life emerged as key motivators to undergoing bariatric surgery. Support from healthcare professionals and family played a crucial role in motivating individuals to consider surgery. Women particularly noted concerns about fertility as a motivator to undergo bariatric surgery. Disclosure of surgery, financial concerns, transport, family and work commitments, and perceived risks of surgery were identified as barriers to undergoing bariatric surgery.
ConclusionFindings highlight the need for healthcare professionals to adopt empathetic, patient-centred approaches when discussing bariatric surgery. Addressing financial, insurance, and logistical barriers, alongside stigma and family resistance, is essential. Improving patient education, strengthening provider relationships, and offering tailored support can enhance decision-making, access, and long-term outcomes for those considering bariatric surgery.
Fluid overload (FO) is a common complication following cardiac surgery with cardiopulmonary bypass (CPB) and is associated with increased morbidity and mortality. Loop diuretics, particularly furosemide, are widely used to promote sodium and water excretion, but their postoperative use remains largely empirical. International guidelines recommend early assessment of diuretic response using spot urinary sodium concentration, traditionally measured by automated laboratory analysers. Recent advances now enable bedside measurement of natriuresis using point-of-care (POC) urinary sodium sensors. This trial aims to determine whether real-time bedside natriuresis monitoring using a POC device can guide safer and more effective diuretic strategies in the postoperative management of FO.
The EASY-CS trial is a prospective, single-centre, open-label, randomised controlled trial designed to evaluate whether a natriuresis-guided furosemide titration protocol improves diuresis within 48 hours following cardiac surgery with CPB. A total of 102 adult patients undergoing elective cardiac surgery with CPB and requiring postoperative intravenous (IV) furosemide for FO will be randomised in a 1:1 ratio to either standard care (n=51; furosemide titration based on clinical judgement) or a natriuresis-guided arm (n=51), in which furosemide dosing is adjusted according to urinary sodium concentration. All patients will receive an initial 20 mg dose of IV furosemide. In the intervention group, urinary sodium will be measured every 6 hours using a POC sodium sensor (LAQUAtwin Na+ metre, Horiba, Japan). If the spot urinary sodium is
Secondary outcomes include urinary sodium concentration and urine output at 24 hours, natriuresis at 48 hours, and the venous excess ultrasound score at 48 hours, as determined by transthoracic echocardiography. The study will also assess total loop diuretic dose administered, cumulative fluid balance over 48 hours and the incidence of postoperative complications at day 30, including cardiovascular, renal, respiratory and gastrointestinal events. Safety endpoints include the presence of hypotension, hypokalaemia or acute kidney injury before each diuretic administration. Randomisation will be stratified by EuroSCORE II (
Ethical approval has been obtained from the Institutional Review Board (IRB) of Amiens University hospital (IRB-ID: 2025-A00925-44). The study’s results will be disseminated through peer-reviewed publications and presentations at national and international conferences.

Commentary on: Ali MR, Lam CSP, Strömberg A, et al. Symptoms and signs in patients with heart failure: association with 3-month hospitalisation and mortality. Heart. 2023 Dec 1. doi: 10.1136/heartjnl-2023-323295.
Implications for practice and research In primary care consultations, symptoms reported by patients with heart failure (HF) could be valuable in identifying patients at risk of hospitalisation or death. Further research needs to investigate how best can support patients to monitor and report symptoms and test new patient-centred prognostic models including HF signs and symptoms.
Hospitalisation in patients with HF is associated with impaired quality of life, increased mortality and excessive medical costs.
