This study aimed to systematically delineate the clinical characteristics and identify the key risk factors associated with methicillin-resistant Staphylococcus aureus (MRSA) infections in burn patients, thereby informing targeted preventive measures and therapeutic strategies. This retrospective study included 270 burn patients with Staphylococcus aureus (S. aureus) infections at a Chinese centre (2019–2022), comprising 127 MRSA and 143 methicillin-susceptible S. aureus (MSSA) cases. Clinical data were analysed to assess infection profiles, resistance patterns and MRSA risk factors. Amongst the infections, 68.1% (184/270) were caused by multi-drug resistant S. aureus, specifically 47.0% (127/270) by MRSA and 21.1% (57/270) by MSSA. The predominant resistance pattern (penicillin, oxacillin, gentamicin, clindamycin, erythromycin, ciprofloxacin, levofloxacin, tetracycline) accounted for 23.9% (44/184) of multidrug-resistant cases. The overall MRSA detection rate was 47.0% (127/270). Univariate analysis identified multiple factors significantly associated with MRSA infection (p < 0.05). Multivariate analysis identified the use of ≥ 3 types of antibiotics as an independent risk factor for MRSA infection in burn wounds. The detection rate of multi-drug resistant S. aureus (including MRSA) infections in burn wounds is relatively high. A number of variables are the influencing factors for MRSA infections. Medical personnel should adopt infection control measures to block the transmission of multi-drug resistant bacteria (including MRSA).
This study aimed to investigate the incidence and characteristics of nursing-sensitive adverse events (NSAEs) in older adults (≥ 65 years) hospitalised with traumatic injuries, and to explore associations with frailty, demographic factors, injury characteristics and hospital-related factors.
NSAEs were identified through a retrospective medical record review of a prospectively collected cohort.
Patients ≥ 65 years admitted with physical trauma to a Swedish level I trauma centre between 2020 and 2024 were included. NSAEs were identified using a modified trigger tool chart review. Descriptive statistics were used to determine the incidence and characteristics of NSAEs in the whole cohort. Group differences, associations and predictors were examined using exact, non-parametric, or logistic regression methods.
A total of 270 trauma patients ≥ 65 years were included, of whom 25.6% had experienced at least one NSAE. The overall incidence was 38.2 events per 100 admissions, with hospital-acquired infections being the most common type of NSAE (16.7%), followed by overdistended bladder (6.3%) and pressure injuries (5.6%). Frailty and length of hospital stay were associated with an increased likelihood of NSAEs, with hospital length of stay emerging as the strongest predictor in multivariable analysis.
NSAEs are common among older trauma patients and are associated with frailty, injury characteristics and length of stay. Improving early risk identification and ensuring timely preventive nursing care may enhance patient safety in this vulnerable population.
The findings highlight the important role of nursing in the care of older trauma patients and the need for consistent delivery of fundamental nursing care. Strengthening clinical practices that support early identification of high-risk patients and the timely implementation of preventive interventions may improve patient safety and outcomes in this vulnerable population.
This study addresses the knowledge gap regarding NSAEs in older trauma patients, a population with increased vulnerability to adverse outcomes. The findings provide insights into the occurrence and risk factors of NSAEs in this group and highlight the importance of translating risk assessment into effective clinical action. These results may inform clinical practice and support the development of strategies to improve patient safety in trauma care for older adults.

To identify the barriers and facilitators to implementing interventions for improving medication adherence in older patients with hypertension.
This review was designed according to the Arksey and O'Malley framework for scoping reviews.
Six electronic databases (PubMed, EMBASE, Web of Science, Cochrane Central Register of Controlled Trials, CINAHL, and PsycINFO) were searched.
This review is written in a consistent format in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews.
Fifteen studies were included in the final analysis. Barriers and facilitators were mapped to 14 constructs across the four CFIR domains. Barriers mapped to ‘intervention characteristics’ spanned multiple constructs, more than any other domain. Similarly, the most frequently mentioned facilitators were derived from the ‘intervention characteristics’ domain. Overall, the intervention content of the existing studies was not generalisable and accessible, whereas other factors such as family involvement in the ‘process’ were effective in facilitating interventions implementation.
This review identified barriers and facilitators to the implementation of interventions to improve medication adherence in older patients with hypertension. Future research should focus on reducing barriers and reinforcing facilitating factors to ensure improved medication adherence in the older population with hypertension.
This review provides a systematic overview of the barriers and facilitators to the implementation of interventions for improving medication adherence in older patients with hypertension. Whether as a barrier or a facilitator, the ‘intervention characteristics’ are predominant. This review will provide guidance for improving medication adherence in older patients with hypertension.

To explore the facilitators and barriers to staff providing psychologically safe care in inpatient mental healthcare when restrictive practices are used.
Qualitative descriptive interview study.
Twenty semi-structured interviews were conducted with staff with experience working in inpatient mental healthcare in England. Analysis included principles of framework analysis, informed by the Theoretical Domains Framework.
Access to resources and a safe environment for both patients and staff were recognised as important (environmental context and resources) but access was impacted by competing organisational priorities and expectations (beliefs about capabilities). Participants recognised knowledge gaps in themselves and their colleagues (knowledge). Being able to confidently make decisions about risk was seen as central to the staff role (social/professional role and identity). Collaboration between staff is needed to make positive change and progression towards psychologically safe care (social influences). Empathy and compassion were driving factors in participants trying to use psychologically informed alternatives, but burnout hindered this (emotions).
Ensuring that staff feel supported in their role to implement psychosocial informed alternatives to restrictive practices, as well as providing safe environments for both patients and staff, could support the integration of psychologically safe care on inpatient mental health wards.
Key facilitators and barriers to staff providing psychologically safe care are identified to support practice and improvements to patient care.

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.

BackgroundDespite increasing attention to youth mental health, children and adolescents in Sweden experience fragmented, inequitable care with regional variation. Delays in diagnosis, limited preventive interventions, and poor inter-sectoral collaboration contribute to significant unmet needs. This study investigates system-level challenges and stakeholder perspectives on opportunities to enhance care pathways.
MethodsWe conducted a qualitative study in the Västra Götaland region, Sweden. Fourteen purposively selected participants – including senior executives, healthcare professionals, and parents took part in semi-structured interviews. We used systematic text condensation, according to Malterud, and the four steps involved in this method for analysing the interviews.
ResultsA central theme across interviews was the requirement for a formal diagnosis before children can access mental health support, particularly in school and primary care settings. Participants described this as a major barrier that delays early intervention and leaves children and young people with complex or atypical presentations without adequate support. Primary care professionals reported increasing mental health caseloads without corresponding increases in staffing or funding, limiting preventive work. Child and adolescent psychiatry (BUP) was described as overwhelmed, with long waiting times and limited continuity of care. A care manager within primary care was proposed as a way to help families navigate fragmented services and improve collaboration, although participants emphasised that such a role would need to be part of broader structural reform.
ConclusionsOur findings highlight persistent systemic issues in mental health care for children and young people, including inequitable access, insufficient prevention, and fragmented collaboration across sectors. Strengthening primary prevention, reallocating resources to primary and school-based mental health care and implementing well-defined care coordination roles within broader restructuring may improve continuity and equity in service delivery. Comprehensive policy reform is needed to support person-centred, integrated care pathways for children and young people with mental health needs.

Bone loss occurs in astronauts during prolonged spaceflight, thus indicating the sensitivity of skeletal homeostasis to altered gravitational environments. Previous studies have shown that microgravity affects osteoclast differentiation and bone resorption, which suggests that osteoclasts possess mechanisms to sense and respond to gravity-generated mechanical forces. For testing of the related mechanisms, hypergravity can be experimentally reproduced with use of a centrifuge. In the present study, osteoclasts derived from mouse bone marrow were subjected to hypergravity under three conditions: 30G exposure using a non-CO2 centrifuge system, and short- or long-term exposure to 3G or 5G using an incubator-compatible centrifuge system. Cytoskeletal organization and resorptive function were assessed using TRAP (tartrate-resistant acid phosphatase) staining, F-actin visualization, and dentin pit assays. In addition, phosphoproteomic analysis was performed after short-term exposure to 5G hypergravity. Hypergravity exposure for as brief as 30 minutes compromised F-actin ring integrity, reduced fluorescence intensity, and promoted nuclear repositioning toward actin rings, whereas tubulin and vinculin localization remained unchanged, and the structural alterations corresponded to attenuated resorption pit formation. Quantitative phosphoproteomic profiling revealed coordinated hypergravity-dependent changes in phosphorylation across multiple cellular modules, including cytoskeletal organization, membrane trafficking, intracellular signaling, and nuclear regulatory pathways. Together, these results indicate that osteoclasts are sensitive to gravity-generated mechanical loading, with hypergravity rapidly modifying F-actin-associated cytoskeleton properties and reprogramming phosphorylation-dependent signaling networks, ultimately attenuating bone-resorptive activity. These findings provide mechanistic insight into how osteoclasts respond to altered gravitational loading conditions and have implications for skeletal adaptation during spaceflight and under altered mechanical loading conditions on Earth.

BackgroundMandibular two-implant overdentures are considered the standard of care for edentulous patients. The attachment system and the shape of the bone crest can significantly influence biomechanical behaviours. This study aimed to evaluate stress distribution in mandibular implant-supported overdentures using locator and bar attachments across various bone crest designs.
Materials and methodsFEA was performed on mandibular overdentures supported by two implants. Three crest configurations (flat, convex, and irregular) were modelled with either bar or locator attachments. A vertical force of 100 N was applied in three loading conditions: anterior, unilateral molar, and bilateral molar. Maximum von Mises stresses and principal stresses were assessed.
ResultsAnterior loading resulted in the highest stresses across all groups, with peak values reaching 12 N/mm² in the convex and irregular models. Bilateral molar loading consistently produced the lowest and most uniform stress distributions, while unilateral loading caused intermediate stress concentrations on the working side. Uneven platforms significantly increased stress levels, particularly under unilateral bar loading. Locator attachments showed slightly reduced stresses after bilateral loading in irregular crest configurations. Stress concentrations were primarily localized at the implant neck and prosthetic connectors.
ConclusionStress distribution in mandibular overdentures is significantly influenced by loading direction, crest shape, and attachment mechanism. Anterior loading poses the highest biomechanical risk, while bilateral posterior loading provides optimal conditions. Vertical discrepancies in implant platforms heighten stress concentrations, underscoring the importance of careful surgical planning. Locator attachments offer limited biomechanical advantages in uneven crest scenarios, supporting their use in anatomically challenging cases.

BackgroundFunctional dyspepsia (FD) is a common gastrointestinal disorder with multifactorial pathogenesis. Recent evidence suggests that duodenal eosinophilia may contribute to low-grade immune activation in FD. This study evaluated the association between increased duodenal eosinophil count and functional dyspepsia.
Materials and methodsThis case-control study was conducted in the Department of Gastroenterology, Sir Salimullah Medical College, Mitford Hospital, Dhaka, Bangladesh, from January to December 2022. Forty-six adult patients with functional dyspepsia diagnosed by Rome-III criteria were included as cases, while forty age- and sex-matched individuals without functional dyspepsia undergoing upper gastrointestinal endoscopy for other indications with normal endoscopic findings served as controls. Multiple biopsies were obtained from the second part of the duodenum. Formalin-fixed paraffin-embedded tissue sections were stained with hematoxylin and eosin. Eosinophils were counted manually by light microscopy in five randomly selected high- power fields (x 400 magnification), and the mean eosinophil count per high-power field (HPF) was calculated.
ResultsThe mean duodenal eosinophil count was significantly higher in patients with functional dyspepsia compared with controls (23.98 ± 7.98 versus 15.63 ± 5.94 eosinophils/HPF, p Conclusions
Patients with functional dyspepsia demonstrated significantly greater duodenal eosinophil infiltration than controls, supporting the role of low-grade immune activation in its pathogenesis. Further multicenter studies with larger samples are required to clarify the clinical implications of duodenal eosinophilia in functional dyspepsia.

BackgroundTo investigate the association between menstrual-related disorders and sexually transmitted infections (STI) among young women in Japan, and to examine differences according to disorder type and hormonal therapy use.
MethodsThis cross-sectional study used the Japan Medical Data Center Claims Database and included women younger than 40 years who had at least one healthcare visit in 2023. Menstrual-related disorders were defined as endometriosis or dysmenorrhea based on ICD-10 codes. The prevalence of five STIs—gonorrhea, genital chlamydia infection, trichomoniasis, genital herpes, and other sexually transmitted conditions—was compared between women with and without menstrual-related disorders. Subgroup analyses were conducted for endometriosis, dysmenorrhea, and hormonal therapy (low-dose estrogen–progestin combinations or dienogest). Prevalence ratios (PR) and prevalence differences (PD) with 95% confidence intervals (CI) were estimated.
ResultsAmong 3,440,929 women, 257,897 (7.5%) had menstrual-related disorders. All STI were substantially more prevalent in this group than in women without menstrual-related disorders, with PRs ranging from 4.31 to 5.29. Endometriosis showed the highest prevalence, particularly for genital chlamydia infection (4.98%; PR 7.44). Dysmenorrhea was also associated with consistently elevated STI prevalence. Among women with menstrual-related disorders, STI prevalence differed only slightly according to hormonal therapy use, with differences generally within one percentage point.
ConclusionMenstrual-related disorders were strongly associated with increased diagnosis of STI in Japanese young women. These findings highlight the importance of integrating STI screening and reproductive health education into routine gynecologic care for women with endometriosis or dysmenorrhea. The influence of healthcare-seeking behavior and diagnostic patterns should be considered when interpreting claims-based STI data.

ObjectiveThis retrospective study evaluated calcitonin as an adjunct therapy for reducing phantom limb pain (PLP) following lower limb amputation.
MethodThe study included 35 patients who received at least 3 days of calcitonin treatment between January 1, 2017, and December 31, 2023. We collected demographic data and pain ratings (intensity, distress, and interference with activity) before and after calcitonin treatment. Descriptive statistics and paired t-tests analysed the data, with a two-way repeated measures ANOVA used to compare outcomes between patients with and without diabetes. Raw and Standardized mean differences (Cohen’s d) are presented for each measure.
ResultsThe average age of participants was 57.09 years (SD = 13.66), with 40% female. Amputation types were below-knee (65.7%), above-knee (25.7%), and other (8.6%). The main causes of amputation included diabetic foot infection (25.7%), peripheral vascular disease (34.3%), trauma (25.7%), and other (14.3%). Ten participants had diabetes, and 20% had depression.Calcitonin was associated with significant reductions in pain outcomes from pre- to post-intervention (Day 0 to Day 7), with calcitonin given from day 1–3. Mean pain intensity decreased from 6.41 to 5.24 (Cohen’s d = 0.66); p = 0.02), and pain-related distress decreased from 5.85 to 4.81 (Cohen’s d = 0.71; p = 0.014). Perceived pain relief scores increased from 33.69 to 58.21, indicating greater patient-reported pain relief following treatment (Cohen’s d = 0.53; p = 0.035). No significant differences in pain intensity or distress were observed between patients with and without diabetes. Additionally, there was no significant change in the Oral Morphine Equivalent Daily Dose (p = 0.94).
ConclusionIn conclusion, calcitonin significantly reduced perceived pain intensity and pain-related distress scores while increasing perceived pain relief scores (i.e., patients’ reported degree of pain reduction), with similar effects observed in both patients with and without diabetes.

Generating mature human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) remains a major obstacle to accurate disease modeling and cardiac repair. As the transcription factor Irx3 is a key determinant of ventricular conduction system fate in mice, we hypothesized that suppressing IRX3 expression accelerates human working cardiomyocyte differentiation. Here, we demonstrate that depleting IRX3 enhances hiPSC-CM differentiation. IRX3-knockout (KO) hiPSCs generated a greater number of cardiomyocytes with elevated expression of TNNI1 and CX43. Notably, IRX3-KO cardiomyocytes exhibited improved electrophysiological properties, more uniform mitochondrial distribution, better sarcomere organization, and enhanced intercellular connectivity. We observed that IRX3 expression peaks during the early stages of cardiomyocyte differentiation, whereas IRX3-KO cardiac progenitors have increased expression of GATA4, NKX2–5, and TBX5, as well as enhanced cell proliferation. These integrative analyses indicate that IRX3 influences cardiomyocyte differentiation by modulating the gene regulatory networks driven by GATA4, NKX2–5, and TBX5, providing functional evidence linking gene regulatory networks to the structural and electrophysiological development of cardiomyocytes. Collectively, these findings identify IRX3 as a key regulator of early cardiac commitment and highlight the potential of IRX3 suppression to enhance the molecular and functional phenotype of hiPSC-derived cardiomyocytes.
To develop predictive models for early and overall tuberculosis (TB) deaths for prospective use at TB diagnosis in resource-constrained TB programme settings.
Statewide cohort study using routinely captured secondary data.
With the majority of TB deaths being early (within 2 months), India’s TB programme’s information management system (Ni-kshay)-dependent death prediction models (using age, gender, TB site, previous treatment, microbiological confirmation, HIV, diabetes and bank account availability) are not feasible for prospective use, as few variables are captured at diagnosis. Utilising routinely captured triage variables for severe illness at diagnosis (body mass index, pedal oedema, respiratory rate, oxygen saturation and ability to stand without support) from an ongoing statewide and state-specific differentiated TB care initiative to reduce TB deaths in Tamil Nadu state (southern India, 80 million population with 0.1 million annual notifications), robust models for prospective use were developed.
Adults (aged ≥15 years) with TB (not known to be drug-resistant at diagnosis) that were notified from public facilities of Tamil Nadu from July 2022 to June 2023.
Early and overall (within 12 months of notification) TB deaths. Area under the receiver operating characteristic curve (AUC) was used to assess accuracy of models built using modified Poisson regression.
Among 55 971 adults, the overall death rate was 7.4%, and 67.9% of the deaths were early. In predicting overall deaths, accuracy of the model using all Ni-kshay variables (AUC 0.716 (95% CI 0.707 to 0.725)) was as good as the model using triage variables for severe illness only (AUC 0.701 (95% CI 0.691 to 0.711)). To the latter, adding potentially capturable Ni-kshay variables at diagnosis (age, gender, TB site, previous treatment and microbiological confirmation) significantly improved model accuracy (AUC 0.754 (95% CI 0.745 to 0.763)). Further addition of remaining Ni-kshay variables did not improve accuracy significantly. Death prediction equations were generated for these models.
Simple and easily measurable triage variables for severe illness should be routinely captured at TB diagnosis. A death prediction calculator (http://44.208.93.99/) based on these variables (specifically triage variables for severe illness combined with age, gender, TB site, previous treatment and microbiological confirmation) may be used by Indian states and high TB burden countries seeking scalable, data-driven interventions to reduce TB deaths.
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.
Loneliness and social isolation are critical public health issues linked to significant adverse health outcomes and increased healthcare utilisation, including visits to the emergency department (ED). The ED often serves as a primary societal safety net, providing care for vulnerable populations who may be disproportionately affected by these conditions. In fact, loneliness and social isolation might be the underlying reasons they presented to the ED in the first place either consciously or not. For such individuals, the ED encounter may represent a rare point of human contact, yet the stressful and depersonalising nature of the ED environment may paradoxically exacerbate their sense of isolation. Furthermore, ED staff may lack the training and awareness of the scope of the problem to properly screen for loneliness and address it. Yet, the compounded impact of the ED experience on lonely or socially isolated patients and the relationship between loneliness and healthcare utilisation remains poorly understood. This paper presents a protocol for a scoping review designed to systematically map the existing evidence on the experiences of these patients and the perspectives of the clinicians who care for them.
This scoping review will be conducted following the Arksey and O’Malley methodological framework in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). The findings will be reported according to the Extension to the PRISMA Statement for Reporting Literature Searches in Systematic Reviews (PRISMA-S; see ). A comprehensive search will be performed across five electronic databases (PubMed, Embase, Scopus, Web of Science, CNKI) and grey literature sources. Studies published in English or Chinese that address loneliness or social isolation in the ED context, from the perspective of adult or paediatric patients or clinical staff, will be included. A novel, artificial intelligence (AI)-assisted screening process will be utilised for initial relevance assessment, followed by full manual screening and data extraction by two independent reviewers to ensure rigour and mitigate bias. Findings will be synthesised using a narrative approach and thematic analysis to identify key concepts, themes and existing gaps in the literature.
As this study synthesises data from previously published literature, it does not require formal ethical approval. The findings will be disseminated through a manuscript submitted to a peer-reviewed, open-access journal. The aim is to provide an evidence-based roadmap to guide future research, inform policy and support the development of interventions designed to improve care and outcomes for this vulnerable population within the acute care setting.

Acute febrile illness is a major cause of morbidity and healthcare seeking in sub-Saharan Africa, including Mozambique. However, few studies have explored the perceptions and practices related to clinical management of acute febrile illness. Our aim was to understand the perceptions, knowledge and practices of healthcare professionals and community members regarding the management of acute febrile illness.
A qualitative study was conducted using a thematic analysis approach. Eight focus group discussions (FGDs) and three in-depth interviews (IDIs) were conducted in two Mozambican provinces across four healthcare facilities. Purposive sampling was used to select participants, comprising both healthcare professionals and community members. Data were analysed thematically through manual coding, applying inductive and deductive approaches, in line with established qualitative analytical frameworks.
The study included a total of 60 participants, 28 healthcare professionals who participated in FGDs (25) and IDIs (3) and 32 community members who participated in FGDs. Major causes of fever, according to healthcare professionals, were upper and lower respiratory infections, malaria, diarrhoeal diseases and COVID-19. The diagnostic approach for febrile patients primarily included screening, malaria testing and other non-specific investigations depending on availability at health facilities. Antibiotics and antipyretics were the most commonly prescribed treatments. The healthcare professionals reported a decrease in prescribing antimalarials due to extensive training on malaria case management. In contrast, community members reported relying primarily on home-based and traditional practices to treat acute febrile illness before seeking care at health facilities. These practices are related to sociocultural habits, such as the use of traditional medicine and self-medication. The main barriers to seeking care at health facilities were the perception of poor quality of care, long waiting times, cultural beliefs and lack of medicines.
Proper management of non-malarial febrile illness remains a major challenge for both healthcare professionals and communities. Training, adherence to case management protocols and efforts to change behaviours to mitigate harmful sociocultural practices are urgently necessary to improve febrile illness management.
