IntroductionHuman papillomavirus (HPV) vaccine prevents over 90% of cervical cancers. In October 2023, Nigeria launched a free HPV vaccination campaign targeting girls aged 9–14 years. Despite removing cost barriers, misinformation about fertility impacts and population control contributed to variable uptake across states. Understanding caregiver decision-making is crucial for improving coverage. This study aimed to explore factors influencing caregivers’ HPV vaccination decisions during Nigeria’s 2023 campaign in Ilorin East Local Government Area, Kwara State.
MethodsA qualitative study using focus group discussions (FGDs) was conducted using purposive and snowball sampling. We recruited 41 caregivers (mean age 47 years; 71% female) of eligible girls from urban and rural communities. Five FGDs were conducted: four with vaccine acceptors (n = 35) and one with decliners (n = 6). Discussions were conducted in Yoruba, audio-recorded, transcribed verbatim, and analysed using Braun and Clarke’s reflexive thematic analysis. Ethical approval was obtained from two institutional review boards.
ResultsFour themes emerged from the analysis. Trust operated at multiple levels: institutional (government programmes), interpersonal (healthcare worker competence), and community (religious/traditional leader endorsement). Historical medical mistrust, intensified by COVID-19 experiences, may have manifested as fertility and population control fears. Personal cancer experiences strongly motivated acceptance, whilst concerns about childhood sexuality influenced timing preferences. Despite free provision, barriers included geographic inequities (remote Fulani-Hausa communities were excluded), language barriers (no Hausa translators), school-based delivery gaps, and indirect costs (transport, time). Caregivers recommended house-to-house campaigns, multilingual services, traditional leader engagement, and permanent vaccination centres.
ConclusionFree vaccine provision is necessary but not sufficient to ensure uptake. Successful HPV vaccination requires rebuilding trust through community engagement, addressing historical medical exploitation concerns, and ensuring equitable access. Integrating these findings into Nigeria’s National Programme on Immunisation could improve coverage from current estimates of 54% to targeted 90%, protecting more girls from cervical cancer whilst respecting community values.
After resuscitation from out of hospital cardiac arrest (OHCA), mechanical ventilation (MV) and respiratory management are fundamental to support patients in the intensive care unit (ICU) and to minimise secondary brain injury. Best practices for MV and association with clinical outcomes in patients with OHCA remain unclear.
This protocol describes a pre-planned respiratory-focused series of sub-analyses within the Sedation, Temperature and Pressure after Cardiac Arrest and Resuscitation (STEPCARE) trial, an ongoing interventional study evaluating 6-month mortality after randomisation in patients admitted to ICUs following OHCA. The primary aim is to describe real-world ventilator settings and gas-exchange targets during the first 72 hours after ICU admission in patients receiving invasive mechanical ventilation after OHCA. Secondary aims include to estimate the incidence of respiratory complications during ICU stay (eg, ventilator-associated pneumonia, acute respiratory distress syndrome, barotrauma); and to explore the association between early ventilator settings/gas-exchange parameters and 6-month outcomes (mortality and neurological status). Exploratory aim is to characterise weaning and extubation practices, including timing and failure rates.
Eligible patients will include adult STEPCARE participants receiving invasive MV after return of spontaneous circulation with available respiratory data recorded within the STEPCARE database.
Data collected in the STEPCARE trial that will be analysed include patients’ prehospital characteristics; clinical examination at hospital admission and at ICU admission; ventilator settings and arterial blood gases recorded at predefined time points during ICU stay. In particular: MV setting (mode, tidal volume, positive end-expiratory pressure, fraction of inspired oxygen, tidal volume, mechanical power, plateau/driving pressures), gas-exchange values (arterial partial pressure of oxygen and carbon dioxide, pH, arterial saturation of oxygen), timing of measurements and the occurrence/timing of respiratory complications and weaning outcomes.
The STEPCARE study has been approved by the regional ethics committee at Lund University (Dnr 2022-02425-01, Approved IRB on 2022-06-18) and by all ethics boards in the participating countries. No additional ethical approval is required for this predefined secondary analysis, as no further data collection or interventions will be performed. Findings will be disseminated through publication in peer-reviewed journals and, where appropriate, conference abstracts and presentations. Patients and the public were not involved.
Active learning strategies, including case-based learning (CBL), problem-based learning (PBL) and team-based learning (TBL), have been extensively studied in clinical and basic science education; however, their application in public health programmes remains under-explored. Public health professionals address population-level challenges that differ substantially from clinical practice, making it necessary to evaluate whether these pedagogies are effective in this field. This review examines how CBL, PBL and TBL have been used in public health education and what outcomes have been reported.
Scoping review was conducted using the Levac and Colquhoun framework, an adaptation of Arksey and O’Malley’s approach.
PubMed, Scopus and Google Scholar were searched for studies published between 2000 and 2025. Eligible studies included those involving students enrolled in undergraduate or postgraduate public health programmes, such as bachelor’s or master’s programmes in public health, epidemiology and biostatistics, global health, community medicine or health policy as well as employees working in public health-related fields. Data were extracted using a predefined template capturing study characteristics, population characteristics, student satisfaction and study objectives. All articles were thematically analysed.
Results
Overall, 22 studies were included. Of these, 11 focused on PBL, 2 on CBL, 3 on both CBL and PBL and 6 on TBL. Public health topics addressed included general public health practice (n=5), global health (n=3), health literacy or education (n=3) and occupational health or medicine (n=2); remaining studies covered leadership, nutrition, health behaviour, climate and health, ageing and mental health. Six themes emerged: skill development, real-world relevance, diversity and inclusion, blended learning, innovative approaches and challenges. Key challenges for PBL included cognitive overload and implementation constraints; for CBL, inequitable participation and resource-intensive implementation; and for TBL, increased student time burden and difficulty adapting to complex simulations.
Active learning methods enhance critical thinking and problem-solving in public health education but face implementation barriers, including faculty training requirements and resource constraints. Future research should examine long-term outcomes and the integration of emerging technologies.
To examine whether exposure to anti-herpetic drugs (AHDs: acyclovir, valacyclovir, famciclovir) is associated with reduced risk of Alzheimer’s disease (AD) treatment initiation.
Population-based retrospective matched cohort study.
University Groningen community pharmacy database IADB.nl, covering approximately 125 Dutch pharmacies (1994–2024).
262 757 adults aged 50–80 years without prior dementia or AD treatment. Exposed individuals with antiherpetic prescriptions (n=23 887) were matched 1:10 to unexposed controls (n=238 870) by age, sex and calendar time.
AHDs: acyclovir, valacyclovir, famciclovir.
Initiation of AD drug treatment, defined as at least two prescriptions for rivastigmine, donepezil, galantamine or memantine within 1 year. Cox proportional hazards models estimated HRs with 95% CIs, adjusted for comorbidities and medications. Analyses were stratified by period (1994–2018 vs 2019–2024) and drug type.
During follow-up, 2495 participants initiated AD treatment. The age of the participants was 65 (SD 9), and 59% were female. Any AHD exposure was associated with 90% reduced hazard of AD treatment (HR 0.09, 95% CI 0.07 to 0.13, p
AHD exposure was consistently associated with markedly lower risk of AD treatment initiation, with similar findings observed in recent years. These findings support the hypothesis that herpesvirus reactivation may contribute to AD pathogenesis and suggest antiviral therapy could have preventive implications. Confirmation through prospective studies and randomised trials is needed.
Ophthalmic complaints account for a substantial proportion of presentations to emergency and acute eye care services, yet initial assessment or referral is frequently performed by non-ophthalmologist healthcare professionals. Previous single-centre studies suggest that one-third of referrals are incorrectly diagnosed, potentially delaying appropriate management of vision-threatening conditions. However, the overall magnitude of diagnostic error and patterns of misdiagnosis across healthcare settings remain unclear. This study aims to systematically review and synthesise the evidence on the diagnostic concordance of ophthalmic referral diagnoses made by non-ophthalmologists in acute eye care.
A systematic review and meta-analysis will be conducted following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols) guidance and registered with PROSPERO. MEDLINE (Ovid), Embase (Ovid) and the Cochrane CENTRAL database will be searched from inception to April 2025. Studies evaluating the diagnostic accuracy of referrals made by non-ophthalmologist healthcare professionals in emergency or acute eye care settings will be included. Two reviewers will independently screen studies, extract data and assess risk of bias using the QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies-2) framework adapted for referral-diagnosis studies. The primary outcome will be diagnostic concordance between referral and final ophthalmologist diagnosis. Where appropriate, pooled concordance proportions will be synthesised using a random-effects meta-analysis. Condition-specific 2x2 diagnostic accuracy analyses will only be undertaken where valid binary target conditions and sufficient denominators are reported. Heterogeneity will be assessed using Cochran’s Q test and the I² statistic with subgroup analyses exploring differences by referring clinician type and anatomical location of ophthalmic pathology.
Ethical approval is not required for this study as it will synthesise data from previously published studies; findings will be disseminated through publication in a peer-reviewed journal and presentation at relevant academic conferences.

South African women are vulnerable to HIV acquisition during the postpartum period which can result in perinatal transmission via breastfeeding; many male partners do not know their HIV status. Biomedical approaches to preventing HIV for postpartum women include pre-exposure prophylaxis (PrEP) and antiretroviral treatment for male partners with HIV. Gaps in implementation include low uptake of PrEP among postpartum women and infrequent testing of men who may be motivated to test for HIV to protect the health of their infant.
We will conduct a randomised pilot trial in KwaZulu-Natal (KZN) Province, South Africa among postpartum women and their male partners. The study will pilot a combination intervention consisting of cognitive behavioural strategies (including communication skills training, motivational interviewing and problem-solving) to promote HIV self-testing (HIVST) for Partners and PrEP uptake for HIV-uninfected Postpartum Women, the ‘H4P’ intervention. The study aims to determine the feasibility, acceptability and preliminary effectiveness of the H4P intervention. We will enrol 60 HIV-uninfected women, aged 18 years and older, in their third trimester of pregnancy and reporting a partner whose HIV-serostatus is unknown. Sixty male partners will also be eligible to enrol. Enrolled women will receive three oral HIVST kits to distribute to their male partners and standard of care information on HIVST and PrEP. Women randomised to the intervention arm will receive additional counselling and reproductive health-centred HIVST information for the male partner, including information about why HIV testing is important during their partners’ postpartum period. To evaluate feasibility, we will calculate screening-to-enrolment ratios for women and men, the number of women who distribute HIVST kits to their male partners and the number of men who test. Acceptability will be evaluated using the Client Satisfaction Questionnaire and qualitative interviews. Effectiveness will be assessed at 3 months by measuring the proportion of women initiating PrEP via self-report and urine tenofovir measurements or receipt of injectable PrEP and the proportion of men who test positive who link to HIV care. Qualitative interviews will explore perceptions of the intervention.
Ethics approval for this study was obtained from the Human Research Ethics Committee at The University of the Witwatersrand, Johannesburg, South Africa (Reference number: 250612) and the Institutional Review Boards at Massachusetts General Brigham (2025P002271, Boston, Massachusetts, USA) and the University of Alabama at Birmingham (300015167, Birmingham, Alabama, USA) in the USA. Site support and approvals were obtained from the health facility and the KwaZulu-Natal Provincial Department of Health. Results will be disseminated through peer-reviewed manuscripts, reports and both local and international presentations.
Previous studies and meta-analyses suggest an association between hypertension and tinnitus; however, the influence of hypertension severity and control status remains unclear.
We aimed to investigate the association between hypertension and tinnitus in detail using a large, population-based dataset from a rural setting.
Design
Observational cross-sectional study.
Setting
Sheshdeh, Fasa, Iran.
We analysed data from 9775 individuals in the general population, aged 35–70 years, excluding those with a history of cancer, pregnancy or medical conditions known to cause tinnitus, such as stroke, seizures or multiple sclerosis. Additionally, although the study design aimed to exclude participants using aminoglycosides because of their significant ototoxic effects, no such users were identified during the study period.
Hypertension was defined as a systolic blood pressure (SBP) of ≥140 mm Hg or a diastolic blood pressure (DBP) of ≥90 mm Hg on at least two separate measurements or as current use of antihypertensive medications following a prior diagnosis. These medications included ACE inhibitors, angiotensin receptor blockers, diuretics, aldosterone antagonists and atenolol. Stage I hypertension was classified as an SBP of 140–159 mm Hg or a DBP of 90–99 mm Hg, while stage II was defined as an SBP of ≥160 mm Hg or a DBP of ≥100 mm Hg. Controlled blood pressure was defined as values below these thresholds. Tinnitus, assessed by a self-reported questionnaire, was defined as a continuous wheezing sound in the ear persisting for more than 1 week.
Among participants (4446 males, 5309 females; mean age 48.55 (SD 9.53) years), the prevalence of tinnitus and hypertension was 7.4% and 19.3%, respectively. Hypertension was significantly associated with higher odds of tinnitus (adjusted OR=1.34; 95% CI 1.10 to 1.62). Notably, even participants with controlled hypertension had a 27% increased odds (OR=1.27; 95% CI 1.02 to 1.59) compared with normotensive individuals. The odds were highest in those with uncontrolled grade II hypertension (OR=2.08; 95% CI 1.25 to 3.47), demonstrating a dose-response relationship.
Our findings suggest a positive association between hypertension and tinnitus, with odds increasing alongside the severity and poor control of hypertension. Importantly, even controlled hypertension was associated with elevated odds, indicating that tinnitus screening may be warranted in all hypertensive patients, regardless of control status. These results underscore the need for heightened clinical awareness and further research into the pathophysiological mechanisms linking vascular health and auditory symptoms.
Poststroke depression (PSD) affects approximately 33% of stroke survivors and is associated with worse outcomes, poor quality of life (QOL) and mortality. Despite its prevalence and consequences, there is no consensus on the most effective strategy for PSD prevention. Behavioural activation (BA) is an effective intervention for depression across diverse populations and is considered safer, better tolerated and a longer-lasting alternative to antidepressant medications. This study aims to test the effectiveness of a remotely delivered BA intervention to prevent PSD (Tele-BA-S).
We will conduct a randomised effectiveness trial of 350 low-income adults (≥ 55 years) within 3 months of ischaemic or haemorrhagic stroke and with subthreshold depression (Patient Health Questionnaire-9 score

Glioblastoma multiforme (GBM) is the most aggressive primary brain tumor in adults, with a median survival of 14.6 months under standard radiotherapy and temozolomide (TMZ) chemotherapy. The methylation status of the O⁶-methylguanine-DNA methyltransferase (MGMT) promoter is a critical biomarker predicting TMZ response; however, its determination currently requires invasive tissue sampling. Non-invasive prediction of MGMT promoter methylation from multiparametric MRI (mpMRI) through deep learning represents a compelling alternative, yet its clinical feasibility remains unresolved. Using the BraTS 2021 dataset (582 patients, four MRI sequences: FLAIR, T1w, T1wCE, T2w), we conducted a systematic comparative study of unimodal and multimodal deep learning approaches based on VGG-16, exploring 1,380 experimental configurations (unimodal: 192; multimodal: 1,188) across three imaging planes, eight slice counts, and three multimodal fusion strategies (early, intermediate, and late fusion). In the unimodal setting, the best model trained on T2w coronal images (32 slices, no transfer learning) achieved an accuracy of 0.6458 and an AUC of 0.6422 on the validation set, but dropped to 0.5586 and 0.5533 on the independent test set, revealing substantial overfitting attributable to limited dataset size. Strikingly, multimodal fusion consistently failed to outperform the best unimodal model, with all three fusion strategies plateauing at ~0.64 accuracy and ~0.64 AUC on validation data. Transfer learning improved generalization across train/test distributions at the cost of peak performance. These findings suggest, for the tested framework in this study, that MGMT methylation status prediction from mpMRI remains fundamentally constrained by dataset heterogeneity and size, irrespective of modality combination strategy, and that T2w coronal acquisitions could be more interesting in future data collection efforts.Large language model tools are increasingly used in higher education, offering opportunities to support self-directed learning. In nursing education, course-specific AI virtual tutors may provide contextualised support while addressing concerns about content accuracy and alignment; yet empirical evidence remains limited.
This study evaluated the use and perceived impact of a co-designed AI-powered virtual tutor embedded in a graduate-level Master of Nursing (MN) course. We explored how students used the tutor, their perceptions of benefits and limitations, and its influence on learning and engagement.
A pilot study using a mixed-methods explanatory sequential design was employed. The tutor was trained on course-specific materials and integrated into the institutional learning management system. Data included anonymised usage logs and user interactions coded using Bloom's Taxonomy of Educational Objectives, post-course surveys assessing AI self-efficacy, usability, and learning impact, and semi-structured interviews with students and teaching assistants (TAs). Quantitative and qualitative strands were integrated through a joint display.
A total of 651 interactions by individuals within a group of ~120 MN students were logged. Interactions peaked in evenings and around assignment deadlines. Most interactions reflected lower-order education processes, with more application and analysis later in the course. Eleven participants completed surveys; students reported high AI self-efficacy and moderate tutor use. Perceived usefulness was mixed, but most reported the tutor enhanced both lower- and higher-level learning and recommended its future use. Interviews revealed that students valued the tutor's immediacy and course-specific accuracy, while TAs noted efficiency gains. Reported challenges included usability issues, scope limitations, privacy concerns, and risk of over-reliance on the tool.
A co-designed AI virtual tutor was feasible and valued for contextual relevance, though perceived usefulness was variable. Findings support responsible, pedagogically integrated use of AI tutors in graduate nursing education.
Diabetic foot ulceration (DFU) contributes significantly to diabetes-related morbidity and amputation. In Barbados, where amputation rates are among the highest globally, the influence of socioeconomic factors on ulceration outcomes remains underexplored. Educational attainment, a social determinant of health, may influence health behaviours, engagement with healthcare services, and ultimately clinical outcomes. This study examines whether educational attainment is associated with diabetic foot ulcer severity, as measured by the SINBAD scoring system, and six-week healing outcomes among inpatients with DFU. A prospective observational study was conducted over 6 months at Barbados' sole public hospital. A total of 176 participants admitted with a diagnosis of DFU were recruited. Baseline demographics, comorbidities, and ulcer characteristics were collected, and SINBAD scores were determined. Random forest modelling was employed to evaluate predictors of complete healing at 6 weeks and to assess ulcer severity stratified by educational attainment. Of the cohort, 17.5% reported primary education as their highest attainment level, compared with 2.9% of the general adult population. The mean SINBAD score was 2.45 among those with primary education and 2.51 among those with secondary education (p > 0.05). No statistically significant association was found between educational attainment and healing outcomes at 6 weeks. Educational attainment in this inpatient DFU cohort was lower than that of the general Barbadian population; however, it was not significantly associated with ulcer severity or six-week healing outcomes. In a universal healthcare setting, equitable access to care may attenuate the effect of educational attainment on clinical outcomes. These null findings highlight the need for future adequately powered studies incorporating health literacy assessment and key clinical confounders. Nonetheless, the observed disparity in educational attainment among DFU inpatients suggests that foot health education initiatives should be designed to be accessible to individuals across all educational levels.
Asthma is one of the most prevalent long-term health conditions affecting pregnant women. Poorly controlled asthma during pregnancy is associated with adverse maternal and fetal outcomes and may predispose offspring to long-term respiratory morbidity. The current ‘one size fits all’ approach to asthma management during pregnancy is not optimally effective for approximately half of the pregnant women with asthma. A personalised medicine approach to managing airways disease is required. The treatable traits approach focuses on the identification and treatment of traits in the pulmonary, extra-pulmonary and behavioural domains, which are identifiable, measurable, clinically relevant (linked to exacerbation risk or poor asthma control) and treatable. This manuscript outlines the protocol for the Treatable Traits for Asthma Management in Pregnancy (TTAP) study. The purpose of the TTAP study is to prospectively determine the prevalence of a range of treatable traits from these three domains in pregnant women with asthma and determine which traits are associated with exacerbation risk, poor asthma control and poor asthma-related quality of life. Additionally, this study will assess differences in trait prevalence and clinical relevance in pregnant women from regional versus metropolitan hospitals in Australia and in different antenatal models of care.
The TTAP study is a multicentre, prospective observational cohort study. Study participants are pregnant women with asthma attending antenatal clinics at 10 metropolitan and regional hospitals (public and private) in NSW and Victoria, Australia. Assessment of traits from the pulmonary, extrapulmonary and behavioural domains as well as asthma outcomes is conducted at three gestational timepoints: 12–16 weeks, 22–26 weeks and 32–36 weeks of pregnancy. A follow-up assessment of asthma outcomes is conducted at 2–4 weeks postpartum. The outcomes assessed are asthma exacerbations requiring medical intervention (primary outcome), asthma symptom control and asthma-related quality of life. Traits and outcomes will be assessed using questionnaires, direct questioning, measurement of biomarkers, physical measurements and assessment of routinely collected data from medical records.
The Hunter New England Human Ethics Committee (2024/ETH01289) has approved the TTAP study protocol. Outcomes will be published in peer-reviewed journals, presented at scientific conferences and disseminated online to participants, clinicians and other pregnant women with asthma and their families via the Asthma in Pregnancy Toolkit website https://asthmapregnancytoolkit.org.au/.

Metabolic reprogramming is central to cancer biology, enabling tumor cells to sustain rapid proliferation, resist stress, and adapt to therapy. However, these alterations are highly heterogeneous across cancer types, and current treatments rarely exploit subtype-specific metabolic vulnerabilities. To address this gap, we developed a unified bioinformatics framework that integrates transcriptomic profiling (UALCAN), drug–gene interactions (DGIdb), gene–disease associations (Open Targets), pathway enrichment (Enrichr), and protein–protein interaction networks (STRING/Cytoscape). This pipeline was applied to lung adenocarcinoma (LUAD), lung squamous cell carcinoma (LSCC), breast cancer (BRCA), and metastatic breast tumors (MET500) to uncover cancer type–specific metabolic programs and prioritize translational targets. Our analysis revealed distinct signatures: LUAD showed glycolytic activation, LSCC coupled glycolysis with oxidative phosphorylation, BRCA favored anabolic and lipogenic pathways, and MET500 tumors adopted stress-adaptive states with elevated antioxidant and autophagy programs. Integration of pharmacological evidence highlighted clinically actionable interactions between metabolic genes and FDA-approved drugs, including ASNS–asparaginase, DHODH–teriflunomide, and G6PD–rasburicase. Gene–disease associations further prioritized G6PD, SLC2A1, and TK1 as robust targets strongly linked to lung and breast cancers. Pathway enrichment pinpointed the pentose phosphate pathway, pyrimidine metabolism, and glutathione metabolism as conserved axes sustaining tumor survival, while network analysis positioned the G6PD–PGD hub as a central metabolic node connecting glucose uptake, redox balance, and nucleotide biosynthesis. To place these bioinformatics-derived findings within a functional and clinical context, we complemented the computational analyses with patient survival assessment, clinical trial screening, and targeted literature appraisal. Survival analysis demonstrated cancer type–specific prognostic relevance for selected metabolic genes, while clinical and literature-based screening revealed both ongoing translational efforts and substantial gaps between computational target prioritization and experimental or clinical validation. This integrative analysis shows that cancer metabolism is altered in subtype-specific ways that can be systematically mapped to reveal potential therapeutic targets. By linking transcriptomic evidence with drug–gene interactions and clinical context, this framework provides a scalable approach for cancer metabolism research and supports the prioritization of pathways with potential translational relevance.by Monalisa M.

BackgroundSickle cell disease is a major cause of childhood mortality in sub-Saharan Africa, yet country-specific burden estimates for high-prevalence settings in West Africa remain limited.
ObjectiveTo describe Global Burden of Disease (GBD) 2023 modeled estimates of sickle cell disorders burden in Sierra Leone from 1990 through 2023, including temporal trends, age and sex patterns, and demographic contributors to mortality change.
MethodsWe analyzed GBD 2023 modeled estimates for sickle cell disorders in Sierra Leone, including prevalence, deaths, years lived with disability (YLDs), years of life lost (YLLs), and disability-adjusted life-years (DALYs) as absolute counts and age-standardized rates. Temporal trends in age-standardized rates were assessed using log-linear regression. The Kitagawa-Das Gupta decomposition partitioned the change in estimated deaths into population growth, age-structure change, and age-specific mortality-rate changes.
ResultsEstimated prevalent cases increased from 48,689 (95% UI, 42,588−56,140) in 1990–90,498 (78,126−105,815) in 2023. Estimated deaths increased from 408 (288−579) to 635 (438−862), while the estimated age-standardized mortality rate declined from 10.2 to 7.9 per 100,000 (APC, −0.46%; 95% CI, −0.64 to −0.29). Decomposition attributed 159.6% of the net increase in deaths to population growth, −7.8% to age-structure change, and −51.8% to lower modeled age-specific rates. In 2023, an estimated 49.5% of deaths occurred before age 20. Point estimates suggested possible higher male mortality, but uncertainty intervals were wide and compatible with no clear sex difference.
ConclusionsGBD estimates suggest that Sierra Leone’s absolute burden of sickle cell disorders increased substantially between 1990 and 2023, while modeled rates declined. These modeled estimates highlight a growing absolute burden and persistent early-life mortality, supporting the need for improved surveillance, newborn screening, infection prophylaxis, hydroxyurea access, and longitudinal care systems.

Oral mucositis is a frequent and debilitating adverse event observed in patients undergoing chemotherapy or radiotherapy. Current management strategies are limited in duration, require frequent application, and fail to address the mechanical irritation from teeth. A novel device, Soft Protector CPC, was developed to overcome these limitations. This multicenter, randomized, two-arm, open-label, confirmatory trial aims to evaluate the efficacy and safety of Soft Protector CPC in patients with breast cancer undergoing chemotherapy. A total of 154 participants will be randomly assigned in a 1:1 ratio to receive either oral care with Soft Protector CPC or oral care alone. The primary endpoint will be oral mucositis as assessed according to the Common Terminology Criteria for Adverse Events (CTCAE) v3.0 during the comparative treatment period. The secondary endpoints will include CTCAE v3.0 during the continuous treatment period, oral mucositis, pain (CTCAE v5.0), quality of life (Patient Reported Outcomes-CTCAE version 1.0 [PRO-CTCAE v1.0], the 15-item oral health questionnaire of the European Organization For Research And Treatment Of Cancer [EORTC QLQ-OH15], and the pain Numeric Rating Scale), onset and site of mucositis, completion of chemotherapy, use of rescue medications, technical feasibility, and patient preference. The safety endpoints will include adverse events, device malfunction, and laboratory tests. This trial is expected to establish the clinical utility of the Soft Protector CPC for the prevention and management of oral mucositis, with the potential to improve the patients’ quality of life and adherence to cancer therapy. This study was approved by the Clinical Research Review Board and registered with the Japan Registry of Clinical Trials, jRCTs062250005, on April 18, 2025.To map how simulation-based education supports the development of critical thinking skills required for nurses to recognize delirium in clinical practice.
A scoping review guided by the Joanna Briggs Institute methodology and the framework developed by Arksey and O'Malley, refined by Levac and colleagues.
Two reviewers independently screened and extracted data to identify studies evaluating simulation-based education designed to strengthen nurses' delirium recognition and associated critical thinking processes. A narrative approach was used to chart and synthesize findings across varied simulation modalities and clinical contexts.
The search was conducted on 4 September 2025, using MEDLINE, CINAHL and PsycINFO. No timeframe was applied to the search.
Fourteen studies met inclusion criteria. Simulation-based education consistently enhanced skills aligned with critical thinking, including observational accuracy, recognition of fluctuating cognitive cues, clinical reasoning, reflective awareness, empathy and communication within interprofessional teams. Structured debriefing played a central role in helping nurses analyse decision-making processes and integrate experiential learning into clinical judgement. Several studies reported changes in practice, including more consistent use of delirium identification tools and improved clarity of clinical documentation.
Simulation-based education strengthens interconnected domains of critical thinking that underpin nurses' capacity to recognize delirium early and respond effectively to its fluctuating presentation. These findings highlight the educational value of immersive, theory-informed simulation for developing the clinical judgement required in cognitively complex patient situations.
Integrating structured simulation into nursing education and professional development may enhance timely delirium recognition, foster more effective interprofessional communication and support safer, higher-quality care for hospitalized adults.
Simulation-based education offers a practical and scalable strategy for improving delirium recognition across care settings. By supporting nurses in noticing subtle cognitive changes, interpreting clinical patterns and communicating concerns with clarity and confidence, simulation contributes to stronger workforce preparedness and patient safety.
This review adhered to PRISMA-ScR reporting guidance.
This study did not include patient or public involvement in its design, conduct or reporting.
