Janus kinase 3 (JAK3) is a hematopoietic-specific kinase implicated in cytokine signaling and immune dysregulation and has recently been associated with cancer progression. However, selective and potent JAK3 inhibitors remain underdeveloped. In this study, we established a machine learning (ML)-based pipeline to identify novel JAK3 inhibitors with anti-cancer potential. A curated ChEMBL dataset of JAK3 inhibitors was used to train multiple ML classifiers, with the Random Forest model achieving the highest performance (AUC = 0.80, F1-score = 0.92). This model was applied to virtually screen 25,084 ChEMBL compounds, yielding 400 high-confidence candidates (prediction score > 0.9). Docking analysis identified ten top binders (binding affinity ≤ –8.5 kcal/mol), of which three CHEMBL49087, CHEMBL4117527, and CHEMBL50064 exhibited optimal ADMET profiles. These compounds underwent 200 ns molecular dynamics simulations, showing low RMSD (0.10–0.20 nm), stable binding conformations, and preserved protein compactness. MM/GBSA calculations revealed that CHEMBL4117527 displayed the strongest binding free energy (–29.5 kcal/mol), surpassing even the co-crystallized ligand (–17.7 kcal/mol). Our integrative approach combining machine learning, docking, pharmacokinetics, molecular dynamics, and free energy analysis presents a robust computational strategy for JAK3 inhibitor discovery. These findings support CHEMBL4117527 as promising candidates for further experimental evaluation in cancer therapeutics.Haematological malignancies and their treatments are known for their significant adverse effects on health-related quality of life (QoL). During high-dose cytotoxic therapy in haematological intensive care units (HICU), adapted physical activity (APA) is recognised for its role in maintaining physical fitness and limiting fatigue. Psychological and emotional states are also impaired, with anxiety levels significantly increasing in this specific context. Limited information is available about this topic. However, APA has been shown to reduce anxiety in various populations, including oncological patients. Furthermore, adding new technology, such as exergaming or heart rate variability biofeedback (HRVB) relaxation tools, could be an effective way to regulate emotions during treatments while providing the health benefits of APA. APA, Exergaming and Relaxation by Biofeedback in Haematological Intensive Care Unit protocol is a randomised, controlled trial. Our study is designed to evaluate the effects of APA programmes during high-dose cytotoxic therapy in HICU on anxiety, fatigue level, functional capacities, immune system activity and global QoL. Additionally, we aim to analyse the added value of using specific devices, such as Exergaming and HRVB relaxation, on the aforementioned parameters. We expect a difference in effectiveness between the programmes concerning emotional regulation.
90 patients (18–75 years), with various forms of haematological malignancies admitted to HICU, with haematologist’s approval for APA, who have given their written informed consent, will be randomly allocated in a 1:1:1 ratio to three 3-week APA groups: APA only (APA), APA by exergaming (EXER), APA+Biofeedback relaxation (BIO) (30:30:30). APA sessions will consist of moderate aerobic training on cyclo-ergometer (classical stationary bicycle for APA, BIO and connected ergometer in EXER), three times per week. The HRVB training will consist of controlled breathing exercises with biofeedback of heart rate variability at the end of each APA session (BIO). The primary outcome is to evaluate the effect of three short APA programmes on state anxiety (Hospital Anxiety and Depression Scale and State and Trait Anxiety Inventory-YA (STAI-YA)). The secondary outcomes will assess the effects on fatigue (Multidimensional Fatigue Inventory–20), physical fitness (2-minute walk test; five-times sit to stand test), QoL (European Organisation for Research and Treatment of Cancer - Quality of Life Questionnary ; EORTC-QLQ-C30) and immune system functioning (blood samples). All of these assessments are evaluated initially (T0) and directly after intervention (T2).

Stroke nurses must perform dysphagia screening on all suspected stroke patients, adhering to best practice guidelines. While comprehensive training is essential for safe and competent screening, the variability in dysphagia screening tools leads to significant differences in education.
This scoping review aims to collate and report what education is provided to stroke nurses on the use of dysphagia screening tools.
A scoping review guided by the PRISMA-ScR checklist.
A systematic review of three electronic databases identified 318 peer-reviewed studies. After screening and eligibility assessment in COVIDENCE, 10 studies were included. Data from these studies was analysed using Arksey and O'Malley's thematic framework.
MEDLINE, CINHAL, Scopus.
Ten studies were included in this review which yielded the following major themes: (1) comprehensive and structured training; (2) diversity of training methods; (3) ongoing education and competency assessment; and (4) standardised protocols and tools.
Offering comprehensive training programs to stroke nurses on dysphagia screening tools is associated with more timely interventions and improved outcomes; however inconsistent approaches to training make it difficult to benchmark outcomes of the education provided. Future research should explore stroke nurses' experiences with current training to guide future training program development.
This review highlights the importance of training stroke nurses to use dysphagia screening tools to improve patient outcomes.

A large bowel cancer chemoprevention potential has been demonstrated by the consumption of carrots, which represent the major dietary source of polyacetylenes. Their interaction with cancer cells and enzyme systems of animals and humans has been systematically investigated over the last 15 years and has now been characterised as anti-inflammatory compounds with antineoplastic effect. Our objective is to investigate whether selected carrot species with a high content of the polyacetylenes falcarinol (FaOH) and falcarindiol (FaDOH) prevent neoplastic transformation and growth in humans, without side effects.
We will conduct a multicentre prospective binational (Denmark and Sweden) randomised controlled trial, with the aim to test the clinical effects of adjuvant treatment with carrot juice in patients who had an excision of high-risk colon adenomas. Patients from six centres will be randomised to receive either anti-inflammatory juice made of carrots high in FaOH and FaDOH or placebo. We will compare the proportion of participants with recurrent adenoma and mean size of them, found in the 1-year follow-up colonoscopy between the two randomised groups.
Informed written consent will be obtained from all participants before randomisation. The study was approved by the regional ethics committee in Denmark (ref. S-20230072) and Sweden (ref. 2024-04732-01). After completion of the trial, we plan to publish two articles in high-impact journals: one article on primary and secondary outcomes, respectively.
This study aimed to assess construct validity against commonly used patient-reported outcome measures (PROMs), test–retest reliability and responsiveness of seven Dutch-Flemish Patient-Reported Outcomes Measurement Information System (PROMIS) computerised adaptive testing (CATs) in Dutch adults with type 2 diabetes (T2D), and assess their acceptability in healthcare providers and people with T2D.
A cross-sectional observational study in people with T2D and qualitative study involving both people with T2D and healthcare professionals.
Participants with T2D were recruited from the ongoing Hoorn Diabetes Care System cohort in the West-Friesland area of the Netherlands. Additionally, people with T2D and advanced chronic kidney disease were recruited at the outpatient clinics of Amsterdam University Medical Centre and ‘Niercentrum aan de Amstel’, both in the Amsterdam area of the Netherlands. The healthcare professionals involved in the qualitative part were recruited at the Amsterdam University Medical Centre.
314 people with T2D (age 64.0±10.8 years, 63.7% men).
Participants completed seven PROMIS CATs (assessing (1) Physical Function, (2) Pain Interference, (3) Fatigue, (4) Sleep Disturbance, (5) Anxiety, (6) Depression and (7) Ability to Participate in Social Roles and Activities), and PROMs measuring similar constructs. After 2 weeks and 6 months, participants completed the CATs measures again, together with seven Global Rating Scales (GRS) on perceived change in each domain. Construct validity was assessed using Pearson’s correlations. Test–retest reliability was assessed by the intraclass correlation coefficient (ICC). Measurement error was assessed by the standard error of measurement (SEM) and minimal detectable change (MDC). Responsiveness was assessed by correlations between change scores on the PROMIS CAT and GRS. Acceptability was assessed through focus groups and interviews in healthcare providers and people with T2D.
Except for Fatigue, all PROMIS CAT domains demonstrated sufficient construct validity, since ≥75% of the results was in accordance with a priori hypotheses. All seven PROMIS CATs showed sufficient test–retest reliability (ICCs 0.73–0.91). SEM and MDC ranged from 2.1 to 2.7 and from 5.7 to 7.4, respectively. Responsiveness was rated as insufficient in this study design as there was almost no change in participants’ own rating of their health compared with 6 months ago according to a global rating of change.
During the focus groups and interviews, healthcare providers and people with T2D agreed that CATs could serve as a conversation starter in routine care, but should never replace personal consultations with a doctor. If implemented, participants would be willing to spend 15 min to complete the PROMIS CATs.
The PROMIS CATs showed sufficient construct validity and test–retest reliability in most domains in people with T2D. Responsiveness needs to be evaluated in a population with poorer diabetes control or in a study design with longer follow-up. The CATs are well accepted to be used in care to identify relevant topics, but should not replace personal contact with the doctor.
On 1 January 2023, Ontario expanded pharmacists’ scope of practice, allowing them to prescribe medications for 13 minor ailments, including antibiotics for uncomplicated urinary tract infections (UTIs) and Lyme disease (LD) prophylaxis. This study evaluates pharmacist billing claims and pharmacist and physician antibiotic-prescribing rates before and after policy implementation.
An interrupted time series analysis measuring changes in prescribing trends post-implementation.
This retrospective study analysed visit claims and antibiotic prescribing for UTIs and LD prophylaxis before policy implementation (2022) and after (2023–2024) in Ontario.
Data from Ontarians
Prescribing rates were standardised per 1000 inhabitants, stratified by provider type, patient age and sex, and antibiotic type.
In 2023 and 2024, pharmacists submitted over 1.47 million minor ailment claims, with UTIs making up 34.2% and LD prophylaxis making up 2.6% of total claims. UTI claims were primarily for women aged 25–64, and LD prophylaxis peaked in spring and fall. Pharmacist prescribing of eligible urinary drugs in females increased by 33.3 per 1000 person-years (95% CI 30.8 to 36.6) while physician prescribing decreased by 23.3 (95% CI –32.2 to –15.3), leading to a modest net increase of 10.1 (95% CI 0.0 to 18.7). Pharmacist prescribing of doxycycline was offset by decreased physician prescribing, resulting in no change (0.0, 95% CI –1.0 to 0.9). Pharmacist prescribing for other antibiotics was low over the study timeframe, while physician prescribing increased, which was driven by increased prescribing of penicillins and macrolides.
There was a clear increase in pharmacist prescribing for eligible drugs in the eligible population post-policy implementation. Pharmacists in Ontario appear to be prescribing within policy limits for uncomplicated UTIs and LD prophylaxis.
Three-quarters of mental health problems start before the age of 25. However, young people are the least likely to receive mental healthcare. Some young people (such as those from ethnic minorities) are even less likely to receive mental healthcare than others. Long-term impacts of mental health problems include poorer physical health, relationships, education and employment. We aim to elicit the views, experiences and needs of diverse young people (aged 16–24 years), to better understand (1) their experiences of under-representation, mental health and coping, (2) mechanisms that shape mental health trajectories and (3) how online arts and culture might be made engaging and useful for young people’s mental health. We also aim to do this with autistic young people.
Narrative inquiry will be employed as a tool for gathering young people’s perspectives for an iterative analysis. The narrative method proposes that critical insights and knowledge are distributed across social systems and can be discovered in personal stories and that knowledge can be relayed, stored and retrieved through these stories. Data will be transcribed and explored using a combination of thematic and intersectional analysis. Young people will be core members of the research team, shape the research and be involved in the coding of data and interpretation of the findings.
This study (IRAS project ID 340259) has received ethical approval from the HRA and Health and Care Research Wales (REC reference 24/SC/0083). The outputs will identify touch points and refine the logic model of how online arts and culture might support the mental health of those from under-represented backgrounds. We will share knowledge with young people, policy makers, health professionals, carers, teachers, social workers and people who work in arts and culture. We will produce research papers, blogs, newsletters, webinars, videos and podcasts.

Inflammation plays a crucial role in homeostasis and defense responses; however, exaggerated and chronic inflammation contribute to the development and worsening of various diseases. Acanthospermum australe (Loefl.) Kuntze (A. australe) is a medicinal plant traditionally used to alleviate inflammation. However, the anti-inflammatory activity of this plant has not yet been explored. This study aimed to evaluate the immunomodulatory activity of this species using network pharmacology, UPLC-ESI-MS/MS analysis, and in vitro assays. Network pharmacology analysis revealed the involvement of immune system processes, and among the main targets of A. australe related to inflammation were innate immune responses, toll-like receptors (TLRs), and T cell receptor signaling pathways. A methanolic extract was prepared and analyzed using UPLC-ESI-MS/MS, and 15 compounds were detected. Additionally, the potential targets of A. australe predicted by network pharmacology analysis were validated in vitro using monocytic THP-1 cells and splenocytes. The RT-qPCR analysis indicated that A. australe significantly inhibited the production of pro-inflammatory cytokines IL-1β, IL-6, and TNF-α, as well as chemokine CCL-2, in lipopolysaccharide (LPS)-stimulated cells. Finally, the extract significantly decreased concanavalin A (ConA)-induced T cell proliferation. Overall, our study provides evidence for the anti-inflammatory effects of this species and highlights its mechanisms of action.To explore the caregiving experiences and support needs of fathers of children with medical complexity in Canada.
A qualitative study guided by interpretive description methodology and informed by a Gender-Based Analysis Plus (GBA+) lens.
Data were collected through 60-min semi-structured interviews with seven fathers of children with medical complexity and analyzed using thematic analysis. The study followed the COREQ guidelines and checklist.
Thematic analysis identified fathers' key roles as financial providers, hands-on caregivers, and as playing a key role in supporting their partners emotionally with the challenges of caregiving. Fathers prioritised the need for peer support, flexible workplace policies and improved access to mental health services.
The findings indicate that there is a critical need for more inclusive and flexible support systems and workplace policies that acknowledge and accommodate the important caregiving roles of fathers of children with medical complexity.
The implications for healthcare professionals include actively involving fathers in care planning and providing targeted support services that recognise their roles to enhance child and family outcomes.
We worked closely with our community advisory team, comprised of a physician, social worker and community organisation leader, who contributed to the study design, supported participant recruitment, and assisted in disseminating the findings back to the community, helping to ensure the research was grounded in and responsive to the needs of families of children with medical complexity.

Gross anatomy dissection is an essential component of medical and health science education, yet it presents notable occupational hazards, particularly from formaldehyde (FA) exposure and microbial contamination. These risks may be intensified in anatomy dissection halls located in tropical monsoon (Am) climates, where elevated humidity and temperature promote both chemical volatility and microbial persistence. This study assessed the combined effects of such climatic conditions on FA concentrations and microbial ecology within a naturally ventilated dissection hall in southern Thailand. FA levels were measured through personal and area air sampling across seven anatomical regions, while microbial contamination on cadaver-contact surfaces was evaluated using culture-based methods and high-throughput sequencing. Functional prediction of microbial communities was performed using PICRUSt2 to assess their metabolic adaptation to environmental stressors. The results revealed that both personal and indoor FA concentrations (mean 1.17 ± 0.39 ppm and 1.09 ± 0.45 ppm, respectively) exceeded several international occupational exposure limits, with the highest levels observed during dissections involving deep or adipose-rich anatomical regions. Microbial analyses identified stress-tolerant and potentially pathogenic genera, including Bdellovibrio, Aequorivita, and Aspergillus spp., along with enriched pathways involved in aromatic compound degradation and environmental resilience. These findings highlight the limitations of natural ventilation in controlling occupational exposures and microbial contamination in Am climate anatomy laboratories. The study supports the implementation of climate-responsive engineering controls and laboratory management strategies that address chemical safety, thermal regulation, and biosafety to promote healthier and more sustainable dissection environments in similar high-risk settings.Deaths related to drug overdose and suicide in the USA have increased 500% and 35%, respectively, over the last two decades. The human and economic costs to society associated with these ‘deaths of despair’ are immense. Great efforts and substantial investments have been made in treatment and prevention, yet these efforts have not abated these increasing trajectories of deaths over time. The COVID-19 pandemic has exacerbated and highlighted these problems. Notably, some geographical areas (eg, Appalachia, farmland) and some communities (eg, low-income persons, ‘essential workers’, minoritised populations) have been disproportionately affected. Risk factors have been identified for substance use and suicide deaths: forms of adversity, neglect, opportunity indexes and trauma. Yet, the biological, psychological and social mechanisms driving risk are not uniform. Notably, most people exposed to risk factors do not become symptomatic and could broadly be considered resilient. Achieving a better understanding of biological, psychological and social mechanisms underlying both pathology and resilience will be crucial for improving approaches for prevention and treatment and creating precision medicine approaches for more efficient and effective treatment.
The State of Ohio Adversity and Resilience (SOAR) study is a prospective, longitudinal, multimodal, integrated familial study designed to identify biological, psychological and social risk and resilience factors and processes leading to mental health disorders, substance use disorders, substance overdose, suicide and associated psychological/medical comorbidities which reduce life expectancy and quality of life. It includes two nested longitudinal samples: (1) WD Survey: an address-based random population epidemiological sample of 15 000 individuals (unique households) representative of the state of Ohio assessed for psychosocial, psychiatric, behavioural health and substance use factors and (2) Brain Health Study: a family-based, multimodal, deep-phenotyping study conducted in 1200 families (up to 3600 persons aged 12–72 years) including MRI, electroencephalography, blood biomarkers and psychiatric diagnostic interviews, as well as neuropsychological, psychosocial functioning and family/community history, dynamics and support assessments. SOAR is designed to discover, develop and deploy advanced predictive analytics and interventions to transform mental health prevention, diagnosis, treatment and recovery.
All participants will provide written informed consent (or parental permission and assent for minors). The study was approved by The Ohio State University Institutional Review Board (study numbers 2023H0316 (Brain Health) and 2023H0350 (Wellness Survey). The Brain Health study was also approved by institutional review boards at each partnering institution involved in conducting participant assessments. Findings will be disseminated to academic peers, clinicians and healthcare consumers, policymakers and the general public, using local and international academic channels (academic journals, evidence briefs and conferences) and outreach (workshops and seminars).
Saskatchewan is facing a public health crisis driven by high rates of HIV, syphilis and hepatitis C virus (HCV) infections, particularly among people who use drugs. Injection drug use is a major contributor to these syndemic infections, exacerbated by structural barriers such as stigma, poverty and limited culturally safe healthcare. Innovative, community-informed approaches are urgently needed to improve prevention, testing and linkage to care.
This study will implement a rapid assessment and response system in Regina, Saskatchewan, Canada, integrating geospatial mapping of community needle prevalence with pop-up interventions. Needle hotspot maps will be used to guide the deployment of community-based pop-up events offering point-of-care testing for HIV, syphilis and HCV, alongside education on pre-exposure prophylaxis (PrEP) and postexposure prophylaxis (PEP). A convergent participatory mixed-methods design will be used to evaluate feasibility, acceptability and effectiveness, guided by the Reach, Effectiveness, Adoption, Implementation and Maintenance framework. Quantitative data will assess changes in knowledge of PrEP and PEP, satisfaction with the intervention and report new diagnoses and participant demographics descriptively. A qualitative substudy will include 30 participants and will explore experiences with the intervention, barriers to care and perceptions of service delivery.
Ethical approval has been obtained from the research ethics board of the Saskatchewan Health Authority (#24–91). Findings will be disseminated through peer-reviewed publications, conference presentations and community reporting. This study may provide a model of community-based geospatial testing and education that could be scaled up and adapted elsewhere.

Despite the known haemostatic action of emicizumab (Hemlibra) in haemophilia A patients, its role in the prevention and control of bleeding in high-demand haemostatic situations, such as major surgery, remains to be determined. Patients receiving regular emicizumab prophylaxis often require concomitant factor VIII (FVIII) therapy during major surgery to prevent uncontrolled bleeding and to promote postoperative healing. However, there are limited prospective surgical data relating to concomitant FVIII and emicizumab use. Simoctocog alfa (Nuwiq) is a B-domain deleted recombinant FVIII produced in a human cell line without chemical modification or protein fusion with proven efficacy as surgical prophylaxis in adult and paediatric patients. The Nuwiq for Perioperative management Of patients With haemophilia A on Emicizumab Regular prophylaxis (NuPOWER) study aims to examine perioperative efficacy and safety of simoctocog alfa in haemophilia A patients on emicizumab prophylaxis undergoing major surgery.
NuPOWER is a prospective, open-label, single-arm, multicentre study that will be conducted at approximately 15 centres worldwide. Up to 28 male patients ≥12 years with severe haemophilia A and no FVIII inhibitors will be recruited. All patients must be receiving regular emicizumab prophylaxis and scheduled to undergo a major surgical procedure during which concomitant simoctocog alfa will be administered. The primary endpoint is the overall haemostatic efficacy of simoctocog alfa, adjudicated by an independent data monitoring committee using a pre-defined algorithm, and will consider intraoperative and postoperative efficacy assessments by the surgeon and investigator, respectively. Secondary endpoints include intraoperative haemostatic efficacy, postoperative haemostatic efficacy, number of allogeneic blood products transfused, perioperative FVIII plasma levels (as measured by FVIII activity) and thrombin generation, and safety parameters. In the era of non-factor therapy, NuPOWER will generate valuable prospective data on concomitant use of simoctocog alfa and emicizumab prophylaxis in patients with severe haemophilia A undergoing major surgery.
Ethical approval has been received from institutional review boards/independent ethics committees, and the study will be conducted in compliance with the Declaration of Helsinki. This work will be disseminated by publication of peer-reviewed manuscripts and presentations at scientific meetings.

During the first wave of the COVID-19 pandemic, there was a notable decline in emergency department (ED) usage in many jurisdictions. This study assessed changes in ED use during this period and explored how the pandemic may have aggravated existing healthcare access inequities.
Our primary objective was to assess pandemic-related changes to ED visits and emergency hospitalisations for distinct demographic groups.
We conducted a retrospective observational study using population-based provincial administrative data.
We analysed data from all the 109 EDs and urgent care centres in Alberta, Canada, during the first wave of the COVID-19 pandemic (15 March 2020 to 30 June 2020), and during the corresponding (control) period 1 year earlier. We conducted subgroup analyses by age, First Nations status, sex, location and material deprivation. We repeated all analyses for pre-selected life-threatening emergency diagnoses.
We examined outcomes for a priori subgroups, including female and ‘other’ sex patients, paediatric patients (age 0–17 years), seniors (age 65 years and older), patients living in remote areas (greater than 200 km from an urban centre), First Nations members and patients living in materially deprived postal codes falling into the two most deprived Pampalon Index quintiles.
Primary outcomes were number of ED visits, number of ED visits with admission to hospital and number of ED visits resulting in patient death in the ED. A secondary outcome was change in ED use for life-threatening diagnoses (eg, cardiac conditions and hepatic disease).
ED visits in the COVID-19 period decreased by 34% (Poisson means test p
Reductions in critical emergency care and emergency hospital admissions were unequally distributed across demographic groups during the COVID-19 period. Study methods could be used to monitor and support equitable access to emergency care among distinct populations.
Early-life exposures, such as nutritional deficiencies, stress, smoking, toxins, medications, diseases, infections and inflammation may affect multiple physiological and metabolic systems in the offspring, including hormonal regulation, bone metabolism and mineralisation, and body composition. Moreover, the effect of these early-life exposures on later health may potentially be mediated through adverse neonatal epigenetic reprogramming of bone-related genes affecting health later in life, especially skeletal development and bone density. Thus, to advance this research further, the overall aim of the project is to investigate if (a) neonatal epigenetic and genetic signature; (b) maternal risk factors during preconception and pregnancy, such as medicine use, diseases, socioeconomic status, major life events, weight, growth and lifestyle; (c) risk factors at birth, such as instrumental delivery, mode of delivery, medicine use, injuries, diseases, weight, size for gestational age, ponderal index, gestational age; and (d) childhood risk factors, such as diseases, medicine use, major life events, weight, growth and lifestyle are associated with hormonal status, lipids, bone turnover markers, bone mineral density, fat mass and lean body mass at age 18–19 years.
Population-based, nationwide, cross-sectional clinical study with potential for longitudinal reassessment. Danish women and men aged 18–19 years old will be selected at random from the Danish National Population Registry and invited if they have available neonatal dried blood spot cards. A total of 2000 individuals will be enrolled. The study combines register data, and neonatal epigenetic and genetic analyses from stored blood with clinical and survey data. Body composition will be measured using dual-energy X-ray absorptiometry. Adult blood and hair samples will be obtained to assess hormonal status, lipids and bone turnover markers. Height, weight, waist and hip circumference, and blood pressure will be measured. Questionnaires on well-being, sleep patterns, dietary and exercise habits, onset of puberty, use of cannabis, nicotine, alcohol and pain medication will be included. Information on medicine use, diseases, socioeconomic status, major life events, weight, growth and lifestyle will be obtained from the national administrative and health registers at the time of conception and during pregnancy for the parents, as well as from the participants throughout their lifetime. Health registries include the Danish Medical Birth Register, the National Patient Register, the Danish National Prescription Register, the National Child Health Register and Statistics Denmark. Multivariate regression analyses will be performed.
This nationwide study has been approved by the Regional Committees on Health Research Ethics for Southern Denmark (S-20230105). The study participants will be enrolled in the study following their informed written consent. Results will be submitted for publication. The Strengthening the Reporting of Observational Studies in Epidemiology Statement guidelines will be used for reporting.
The number of people living with dementia is increasing worldwide. Alzheimer’s disease (AD) is the most common type of dementia. It typically manifests itself initially with cognitive impairment in the memory domain and gradually progresses towards affecting all activities of daily living. Active music interventions, particularly singing, may improve mood, social behaviour and quality of life. However, little is known about their effects on cognition, although some studies have provided promising results. The Memory for Music (M4M) project aims to fill this gap in research by measuring the effects of learning new songs on cognitive functioning. Specifically, M4M will examine memory for new songs in non-musician adults with AD after undergoing intensive versus minimal individual musical training based on singing novel songs.
Home-dwelling adults with AD, 65 years or older, will receive 5 months of intensive intervention (2x/week) and 5 months of minimal intervention (1x/month). In a crossover design, participants will be randomised to receive either the intensive or minimal intervention first, with 2 months between the intervention periods. Participants will receive individual music lessons to learn new songs, provided by a music instructor with adequate training. The main outcomes will be measured at the beginning and end of each intervention period. General cognition will be measured with the AD Assessment Scale – Cognitive by an assessor blinded to the randomisation. Participants’ memory for music will be measured using the N400 component of electroencephalographic (EEG) event-related potentials in response to music stimuli. Additional outcomes evaluated during intervention sessions include mood and musical performance observations. With 113 participants randomised, the trial will have 80% power to detect clinically meaningful effects. Relations between mood, memory for music and cognitive abilities will be examined, with sex, age, AD stage, previous musical training and education as covariates. M4M will be conducted in close collaboration between academic researchers, service providers and service users to ensure relevance and applicability.
Dissemination of findings will apply to local, national and international levels. The study has been approved by the Regional Committees for Medical and Health Research Ethics in Norway (reference number 759936) and by Mautalén Salud e Investigación, CECOM in Argentina (register code 14412).

To develop precision health (PH) competencies and evaluate their comprehensiveness and fit into nursing practice.
A modified e-Delphi technique was used to gather perceptions and achieve consensus on the inaugural set of PH domains, competency statements and sub-competencies developed by a workgroup formed under the aegis of the American Nurses Association (ANA).
A set of PH competencies and sub-competencies was developed by the ANA workgroup, beginning with a literature review, followed by a multi-step work process of the group over 3 years (2022–2025). Then, a modified e-Delphi technique was conducted via a four-point Likert scale Qualtrics survey, using a purposive sample of PH experts. The respondents were asked to agree or disagree with each competency or sub-competency statement and suggest modifications. The threshold of concordance was set at 80%.
The ANA workgroup reached consensus on six domains, six competency statements and 43 sub-competency statements to represent PH in nursing practice in its entirety. Forty experts in the field evaluated and offered revisions to the final 44 sub-competencies that represent the knowledge and skills necessary for PH in general nursing practice. A majority of the competency statements obtained favourable agreement from the expert panel, and a typical pattern of convergence was observed over two rounds of evaluation.
The development of PH competencies is the essential first step in the attempt to integrate PH into nursing practice.
The competency statements will inform nursing curricula, clinical practice guidelines, funding opportunities and role expectations in all healthcare settings.
This work sets the stage for subsequent interprofessional practice initiatives and research exploring how these competencies influence patient outcomes, workforce readiness and the practical integration of advanced technologies into precise care.
Effective community-based disease management is essential for public health. In low- and middle-income countries, sustainable strategies for timely diagnosis and treatment are a research priority. This study aims to assess the feasibility of a non-invasive saliva self-sampling method, paired with digitally linked molecular point-of-care diagnostics, for detecting respiratory infections among paediatric patients in the Tshwane District, South Africa.
A field study will be conducted at Steve Biko Academic Hospital to compare saliva collection using the CandyCollect lollipop device and standard mouth swabs. The spiral groove of the lollipop device captures pathogens, which are stored in DNA/RNA preservation media and later analysed using quantitative PCR and commercially available rapid antigen tests. The multiplex respiratory pathogen panel, based on TaqMan real-time PCR technology, targets key paediatric pathogens including Streptococcus pneumoniae, Haemophilus influenzae, Mycoplasma pneumoniae, respiratory syncytial virus (RSV) and influenza A/B. Nucleic acids will be extracted using standard viral extraction kits and analysed following manufacturer protocols. Internal controls will be included in each qPCR run, and samples with CT values below defined thresholds will be considered positive. Rapid antigen tests will detect common pathogens such as influenza A/B, RSV and SARS-CoV-2 for comparative analysis. User experience and acceptability will be assessed via child-friendly and caregiver surveys following sample collection. The study will be implemented in two phases: diagnostic performance evaluation and user feedback assessment. The protocol is aligned with the Standard Protocol Items: Recommendations for Interventional Trials 2013 checklist.
Ethical approval has been granted by the University of Pretoria (509/2023) and the Gauteng Department of Health (GP_202406_032).

Providing care in a patient’s preferred language improves health outcomes and patient satisfaction. In Ontario, access to French-speaking physicians (FSPs) is estimated using FSP-to-Francophone population ratios and compared with total physician-to-total population ratios. This approach fails to consider the fact that FSPs also serve non-Francophone patients and that Francophones must compete with the entire population to access FSPs. As a result, this approach inaccurately suggests that Francophones have better access to language-concordant care than Anglophones/Allophones. We propose a novel approach to address this issue, enabling unbiased comparisons of access to language-concordant care across linguistic groups.
This secondary analysis of publicly available data containing linguistic variables for the Ontario population (Statistics Canada, 2021 Census) and for family physicians (FPs) (College of Physicians and Surgeons of Ontario, January 2024) calculated competition-adjusted ratios and probabilities of accessing language-concordant care.
Ontario, Canada.
Census and publicly available data on FPs (ie, those providing comprehensive family medicine care to the community) and the Ontario population were obtained.
Province-wide, the crude ratio of FSPs per 1000 Francophones was 3.46. After adjusting for competition, the ratio of FSP per 1000 population was 0.12, compared with a general physicians-per-1000 population ratio of 1.05. Anglophones/Allophones attached to a FP have a 100% probability of receiving care in English compared with an 11.4% probability for Francophones to receive care from a FSP. Expressed otherwise, Anglophones/Allophones are 8.8 times more likely to receive language-concordant care (ie, care in English) than Francophones.
Although crude physician-to-population ratios overestimate Francophones’ access to FSPs, competition-adjusted ratios and probabilities demonstrate that they are much less likely to access language-concordant care than Anglophones/Allophones. This novel approach has equity implications for health human resources planning and can be applied to other linguistic minority groups and healthcare providers.
To evaluate the research capability of clinical nurses in China and identify the determinants associated with their capability.
As nursing evolves into an increasingly independent discipline, the research capability of clinical nurses has become critical for the development of the profession, advancing evidence-based practice and improving patient care quality.
A multicentre cross-sectional survey was conducted using convenience sampling from September 2023 to February 2024, among clinical nurses in tertiary hospitals across three provinces in China. The Nursing Research Capability Self-Assessment Scale was used to assess the research capability of the nurses. Chi-square tests, one-way analysis of variance and multiple linear regression were used to examine factors associated with research capability. The Strengthening the Reporting of Observational Studies in Epidemiology was followed.
A total of 1074 clinical nurses participated. The mean research capability score was 89.11 ± 27.69, reflecting a moderate level of research capability. However, two dimensions of research questions and literature review received lower scores. Multiple linear regression analysis identified that education level, professional title, administrative position and nursing job title (all p < 0.05) were independent predictors of research capability.
Clinical nurses exhibit moderate research capability, with notable deficiencies in formulating research questions and conducting literature reviews. Key factors influencing research capability include education, professional title, administrative position, and job title. Targeted training and development programmes should address these factors to enhance nurses' research competence and advance nursing science.
