by Nour Aboalhaija, Hala Abulawi, Rania Hamed, Mohammad Alwahsh, Fatma Afifi, Heba Syaj, Elham Abusharieh, Ismail Abaza

Chiliadenus montanus (Vahl) Boiss. (Asteraceae) is a pharmacologically significant plant with different potent pharmacological properties. This study aimed to evaluate the phytochemical and anticancer activity of C. montanus, and to develop nanoemulsions (NEs) to enhance pulmonary delivery for lung carcinoma treatment. For that ethanol and water extracts, along with petroleum ether, chloroform, ethyl acetate, and methanol fractions, were assessed for total phenol and flavonoid contents, antioxidant activity, and cytotoxicity against H1299 and A549 lung cancer cell lines. The results showed that ethyl acetate fraction exhibited the highest phenol (47.94 ± 0.32 mg GAE/g of DW) and flavonoid (20.34 ± 1.48 mg rutin/g of DW) contents, while the ethanol extract showed the most potent antioxidant activity (IC₅₀ = 322.1 µg/mL) and selective cytotoxicity (IC₅₀ = 641.2 µg/mL) against H1299 cells. Nevadensin, chlorogenic acid, and sorbifolin were identified as the major constituents of the ethanol extract using liquid chromatography-mass spectrometry (LC-MS) analysis. Gas chromatography-mass spectrometry (GC-MS) analysis revealed α-phellandrene, 1,8-cineole, and α-cadinol as the lead volatile constituents. The major volatile compound of the aroma profile of the aerial parts, determined by solid phase micro extraction (SPME) was 1,8-cineole. Spontaneous emulsification was used to formulate ethanolic NE (S1-S4 NEs) with varying concentrations of ethanol extract, surfactant, cosurfactant, and oil phase. The optimal S4 NE demonstrated thermodynamic stability, appropriate pulmonary pH, and droplet sizes below 100 nm. These findings highlight the promising potential of C. montanus NE as a stable pulmonary drug delivery system for lung carcinoma therapy.

Purpose

Multiple sclerosis (MS) is a chronic neurological condition that affects approximately 150 000 people in the UK and presents a significant healthcare burden, including the high costs of disease-modifying treatments (DMTs). DMTs have substantially reduced the risk of relapse and moderately reduced disability progression. Patients exhibit a wide range of responses to available DMTs. The Predicting Optimal INdividualised Treatment response in MS (POINT-MS) cohort was established to predict the individual treatment response by integrating comprehensive clinical phenotyping with imaging, serum and genetic biomarkers of disease activity and progression. Here, we present the baseline characteristics of the cohort and provide an overview of the study design, laying the groundwork for future analyses.

Participants

POINT-MS is a prospective, observational research cohort and biobank of 781 adult participants with a diagnosis of MS who consented to study enrolment on initiation of a DMT at the Queen Square MS Centre (National Hospital of Neurology and Neurosurgery, University College London Hospital NHS Trust, London) between 01/07/2019 and 31/07/2024. All patients were invited for clinical assessments, including the expanded disability status scale (EDSS) score, brief international cognitive assessment for MS and various patient-reported outcome measures (PROMs). They additionally underwent MRI at 3T, optical coherence tomography and blood tests (for genotyping and serum biomarkers quantification), at baseline (i.e., within 3 months from commencing a DMT), and between 6–12 (re-baseline), 18–24, 30–36, 42–48 and 54–60 months after DMT initiation.

Findings to date

748 participants provided baseline data. They were mostly female (68%) and White (75%) participants, with relapsing–remitting MS (94.3%), and with an average age of 40.8 (±10.9) years and a mean disease duration of 7.9 (±7.4) years since symptom onset. Despite low disability (median EDSS 2.0), cognitive impairment was observed in 40% of participants. Most patients (98.4%) had at least one comorbidity. At study entry, 59.2% were treatment naïve, and 83.2% initiated a high-efficacy DMT. Most patients (76.4%) were in either full- or part-time employment. PROMs indicated heterogeneous impairments in physical and mental health, with a greater psychological than physical impact and with low levels of fatigue. When baseline MRI scans were compared with previous scans (available in 668 (89%) patients; mean time since last scan 9±8 months), 26% and 8.5% of patients had at least one new brain or spinal cord lesion at study entry, respectively. Patients showed a median volume of brain lesions of 6.14 cm3, with significant variability among patients (CI 1.1 to 34.1). When brain tissue volumes z-scores were obtained using healthy subjects (N=113, (mean age 42.3 (± 11.8) years, 61.9% female)) from a local MRI database, patients showed a slight reduction in the volumes of the whole grey matter (–0.16 (–0.22 to –0.09)), driven by the deep grey matter (–0.47 (–0.55 to –0.40)), and of the whole white matter (–0.18 (–0.28 to –0.09)), but normal cortical grey matter volumes (0.10 (0.05 to 0.15)). The mean upper cervical spinal cord cross-sectional area (CSA), as measured from volumetric brain scans, was 62.3 (SD 7.5) mm2. When CSA z-scores were obtained from the same healthy subjects used for brain measures, patients showed a slight reduction in CSA (–0.15 (–0.24 to –0.10)).

Future plans

Modelling with both standard statistics and machine learning approaches is currently planned to predict individualised treatment response by integrating all the demographic, socioeconomic, clinical data with imaging, genetic and serum biomarkers. The long-term output of this research is a stratification tool that will guide the selection of DMTs in clinical practice on the basis of the individual prognostic profile. We will complete long-term follow-up data in 4 years (January 2029). The biobank and MRI repository will be used for collaborative research on the mechanisms of disability in MS.

Career Growth as a Mediator Between Scope of Practice, Importance of Practice and Emergency Nursing Competency Among School Nurses

ABSTRACT

Background

School nurses are sometimes the sole healthcare professionals in schools, highlighting their significant role in delivering emergency care and the vital necessity of their competence in emergency nursing care. The scope of practice and ongoing professional development are hypothesized to play significant roles in enhancing these competencies.

Aim

Investigate the direct and indirect effects of the scope of current practice and the importance of training on the emergency nursing care competency of school nurses, with career growth serving as a potential mediator.

Methods

A multi-center cross-sectional study was conducted with a convenient sample of 219 school nurses. Data were collected using the career growth of nurses' scale, the emergency nursing care competency scale for school nurses and the scope of school nursing practice tool. Mediation analysis was used to explore the direct and indirect effects of studied variables.

Results

Mediation analysis indicated that the scope of current practice had a significant direct effect on career growth (β = 0.179) and emergency nursing care competency (β = 0.389). The importance of practice also had significant direct effects on career growth (β = 0.164) and emergency nursing care competency (β = 0.220). Additionally, career growth significantly mediated the relationship between both the scope of current practice (β = 0.110) and the importance of practice (β = 0.120) with emergency nursing care competency.

Conclusions

The findings emphasis the critical role of career growth as a mediator between the scope and importance of practice and emergency nursing care competency among school nurses. Expanding the scope of practice and emphasising the importance of professional activities can enhance career growth and improve emergency nursing care competencies.

Implications

Nurses scope of practice and clear career advancement through mentorship, advanced certifications, further education and enforcing policies mandating regular emergency care is crucial. Establishing a regulatory framework to define and expand the scope of practice for school nurses is also important.

Household resilience and its role in sustaining food security in rural Bangladesh

by Ismat Tasnim, Md. Asif Iqbal, Ismat Ara Begum, Mohammad Jahangir Alam, Morten Graversgaard, Paresh Kumar Sarma, Kiril Manevski

Food insecurity and agriculture in South Asia, including Bangladesh, pose significant threats to the well-being and livelihoods of its people. Building adaptive capacities and resilient food systems is crucial for sustainable livelihoods. This study employs the Resilience Index Measurement and Analysis II framework to construct a Resilience Capacity Index (RCI) and analyze its relationship with food security using data from the Bangladesh Integrated Household Survey 2018. The study applies Exploratory Factor Analysis and Structural Equation Modeling to examine the impact of key resilience components such as Access to Basic Services, Adaptive Capacity, and Assets on household resilience. The findings reveal that access to basic services, land assets, and farm equipment positively influences households’ resilience capacity. However, the presence of livestock assets has a negative impact, potentially due to market volatility, climate vulnerability, and disease outbreaks. Additionally, adaptive capacity has a positive but insignificant influence on RCI, suggesting that without enhancing economic opportunities, institutional support, and inclusive development strategies, adaptive capacity could not be enough to foster resilience. However, resilient capacity enhances food security metrics such as the Food Consumption Score and Expenditure. These findings underscore the importance of policies that focus on increasing and maintaining access to basic services, promoting sustainable land management practices, and strengthening social safety nets. This study emphasizes the importance of focusing on livestock assets to ensure their sustainability by stabilizing the livestock market, improving veterinary services, and providing subsidies to reduce maintenance costs.

Por: Chan · S. L. · Yap · C. J. Q. · Xu · Y. · Chia · S. Y. · Mohamed Salim · N. N. B. · Lim · D. M. · Choke · E. · Carmody · D. · Tan · G. C. S. · Goh · S.-Y. · Bee · Y. M. · Chong · T. T.
Objective

This study aimed to determine the association between diabetes mellitus (DM) medication use and glycaemic control.

Design

This was a retrospective diabetes registry-based cohort study.

Setting

Singapore.

Participants

Patients aged 18 and above with incident DM in the SingHealth Diabetes Registry from 2013 to 2020 were included. The entire study period included a 1 year baseline period, a 1 year observation period and a 3 month outcome period.

Outcome measures

Drug use was measured using the proportion of days covered (PDC), and the changes in glycated haemoglobin (HbA1c) between the outcome and baseline periods were assessed. The associations between baseline HbA1c and PDC ≥0.80 and between PDC and change in HbA1c were analysed using logistic regression and the Kruskal–Wallis test, respectively.

Results

Of 184 646 unique patients in the registry from 2013 to 2020, 36 314 met the inclusion and exclusion criteria and were included in the analysis. The median PDC for any DM drug, oral DM drugs and insulin during the observation period was 20.3%, 16.8% and 0%, respectively. Those who had good glycaemic control at baseline were less likely to receive DM drugs and those with poor baseline glycaemic control or missing baseline HbA1c were more likely to be consistent users (PDC >80%) (px 10-16).

Conclusion

The relationship between DM drug use and glycaemic control is complex and non-monotonic. Higher PDC for any DM drug and oral DM drugs during the observation period was significantly associated with clinically relevant HbA1c improvements.

Structural stability-guided scaffold hopping and computational modeling of tankyrase inhibitors targeting colorectal cancer

by Mohammed Merae Alshahrani

Colorectal cancer is one of the leading causes of cancer-related deaths worldwide, mainly due to aberrant Wnt/β-catenin signaling resulting from APC mutations. Tankyrase is a key regulator of this pathway and plays a crucial role in stabilizing AXIN, a negative regulator of β-catenin, and hence an attractive therapeutic target. The present study describes a comprehensive computational approach to discovering novel tankyrase inhibitors for CRC therapy. The reference (RK-582) for ligand-based screening and comparative analysis was taken from the crystal structure of tankyrase. A similarity search in the PubChem, applying an 80% cutoff, yielded 533 structurally similar compounds. These compounds were subjected to virtual screening using a drug-likeness filter. The top-ranking binding poses of three selected compounds (PubChem CIDs: 138594346, 138594730, and 138594428) were selected for DFT calculation and re-docking. DFT calculations revealed that compound 138594428 had the largest HOMO-LUMO gap (4.979 eV), indicating high electronic stability, while 138594346 exhibited a strong balance of stability and reactivity (4.473 eV). The MD simulations were conducted on all ns protein-ligand complexes for 500 ns, exploring their stability. MD simulations confirmed the conformational stability of these compounds, with 138594346 showing the lowest RMSD and RMSF fluctuations. Additionally, a machine learning model trained on 236 known Tankyrase inhibitors accurately predicted pIC₅₀ values, with compound 138594346 (pIC₅₀ = 7.70) closely matching the reference inhibitor (pIC₅₀ = 7.71), and 138594428 also exhibiting strong predicted activity (pIC₅₀ = 7.41). Collectively, these results highlight 138594346 and 138594428 as promising candidates for further experimental validation in the development of targeted CRC therapeutics.

Introduction

In 2022, the WHO conditionally recommended the use of treatment decision algorithms (TDAs) for treatment decision-making in children

Methods and analysis

Within the Decide-TB project (PACT ID: PACTR202407866544155, 23 July 2024), we aim to generate an individual-participant dataset (IPD) from prospective TB diagnostic accuracy cohorts (RaPaed-TB, UMOYA and two cohorts from TB-Speed). Using the IPD, we aim to: (1) assess the diagnostic accuracy of published TDAs using a set of consensus case definitions produced by the National Institute of Health as reference standard (confirmed and unconfirmed vs unlikely TB); (2) evaluate the added value of novel tools (including biomarkers and artificial intelligence-interpreted radiology) in the existing TDAs; (3) generate an artificial population, modelling the target population of children eligible for WHO-endorsed TDAs presenting at primary and secondary healthcare levels and assess the diagnostic accuracy of published TDAs and (4) identify clinical predictors of radiological disease severity in children from the study population of children with presumptive TB.

Ethics and dissemination

This study will externally validate the first data-driven WHO TDAs in a large, well-characterised and diverse paediatric IPD derived from four large paediatric cohorts of children investigated for TB. The study has received ethical clearance for sharing secondary deidentified data from the ethics committees of the parent studies (RaPaed-TB, UMOYA and TB Speed) and as the aims of this study were part of the parent studies’ protocols, a separate approval was not necessary. Study findings will be published in peer-reviewed journals and disseminated at local, regional and international scientific meetings and conferences. This database will serve as a catalyst for the assessment of the inclusion of novel tools and the generation of an artificial population to simulate the impact of novel diagnostic pathways for TB in children at lower levels of healthcare. TDAs have the potential to close the diagnostic gap in childhood TB. Further finetuning of the currently available algorithms will facilitate this and improve access to care.

Objectives

To evaluate the effects of diabetes mellitus (DM) and body mass index (BMI) on long-term all-cause mortality in chronic total occlusion (CTO) patients.

Design

Retrospective, nationwide cohort study.

Setting

Swedish Coronary Angiography and Angioplasty Registry, between June 2015 and December 2021.

Participants

24 284 patients with angiographically confirmed CTO. Prior coronary artery bypass graft surgery excluded. Subgroups were defined by DM status and BMI categories (underweight, healthy weight, overweight, obesity).

Primary outcome measures

Long-term all-cause mortality, assessed by Kaplan-Meier analysis and multivariable Cox proportional hazards regression.

Results

DM was present in 30.3% of patients and conferred a 31% higher risk of mortality (HR: 1.31, 95% CI: 1.20 to 1.42; p2, lowest risk (nadir) at 32 kg/m2 and modest rise above 35 kg/m2.

Conclusions

In this nationwide CTO cohort, DM independently predicted higher long-term mortality, accompanied by more severe comorbidities and greater CTO complexity, and insulin therapy further elevated hazard. Overweight and obese patients had better survival, while underweight individuals had the poorest prognosis. These findings underscore the importance of individualised risk assessment and management strategies in CTO patients, particularly those with DM or low BMI.

Is anaemia associated with QTc prolongation? A retrospective cross-sectional analysis from a rural population-based cohort

Por: Bazmi · S. · Mohammadi · Z. · Motazedian · M. · Tabrizi · R.
Background

Prolonged QTc is a major risk factor for ventricular arrhythmias and sudden cardiac death (SCD). Anaemia’s impact on the QT interval is unclear and conflicting despite its association with increased mortality.

Objective

We investigated the association between anaemia and the prevalence of QTc prolongation, as well as potential gender differences in this relationship. Additionally, we examined whether haemoglobin levels were associated with QTc prolongation.

Design

Observational cross-sectional study.

Setting

Sheshdeh, Fasa, Iran.

Participants

We analysed data from 5741 participants from the general population (aged 35–70 years) with no history of ischaemic heart disease; myocardial infarction; amiodarone use; multiple blood transfusions; or supplementation with iron, folic acid or cobalamin.

Primary and secondary outcomes

Anaemia was defined according to WHO guidelines (haemoglobin 450 ms in men or >470 ms in women.

Results

Among 5741 participants, mean QTc was 427.91±24.75 ms, with QTc prolongation in 7.14%. Anaemia raised the odds of QTc prolongation by 60% (OR=1.60, 95%CI 1.12 to 2.28, p=0.010), particularly in females (OR=1.73, 95%CI 1.12 to 2.66, p=0.013), but not in males. Higher haemoglobin levels were associated with lower QTc prolongation risk (OR=0.91 per unit increase, 95% CI 0.85 to 0.97, p=0.005). No significant associations were observed between anaemia type/severity and QTc prolongation among anaemic individuals.

Conclusion

Anaemia was significantly associated with QTc prolongation, particularly in females. Anaemia type/severity did not affect QTc prolongation. Anaemia is associated with increased odds of QTc prolongation, particularly in women. While causality cannot be inferred from this cross-sectional analysis, the findings suggest that clinicians may consider QTc monitoring in anaemic patients, especially women and exercise caution when prescribing QT-prolonging medications. Prospective studies are needed to confirm whether anaemia directly contributes to QTc prolongation or arrhythmic risk.

Objectives

This study aimed to analyse the number of myocardial infarction (MI) admissions during the COVID-19 lockdown periods of 2020 and 2021 (March 15th to June 15th) and compare them with corresponding pre-pandemic period in 2019. The study also evaluated changes in critical treatment intervals: onset to door (O2D), door to balloon (D2B) and door to needle (D2N) and assessed 30-day clinical outcomes. This study examined MI care trends in India during the COVID-19 lockdown period, irrespective of patients’ COVID-19 infection status.

Design

Multicentre retrospective cohort study

Setting

Twenty-three public and private hospitals across multiple Indian states, all with 24/7 interventional cardiology facilities.

Participants

All adults (>18 years) admitted with acute myocardial infarction between March 15 and June 15 in 2019 (pre-pandemic), 2020 (first lockdown) and 2021 (second lockdown). A total of 3614 cases were analysed after excluding duplicates and incomplete data.

Primary outcomes

Number of MI admissions, median O2D, D2B and D2N times.

Secondary outcomes

30-day outcomes including death, reinfarction and revascularisation.

Results

MI admissions dropped from 4470 in year 2019 to 2131 (2020) and 1483 (2021). The median O2D increased from 200 min (IQR 115–428) pre-COVID-19 to 390 min (IQR 165–796) in 2020 and 304 min (IQR 135–780) in 2021. The median D2B time reduced from 225 min (IQR 120–420) in 2019 to 100 min (IQR 53–510) in 2020 and 130 min (IQR 60–704) in 2021. Similarly, D2N time decreased from 240 min (IQR 120–840) to 35 min (IQR 25–69) and 45 min (IQR 24–75), respectively. The 30-day outcome of death, reinfarction and revascularisation was 4.25% in 2020 and 5.1% in 2021, comparable to 5.8% reported in the Acute Coronary Syndrome Quality Improvement in Kerala study.

Conclusion

Despite the expansion of catheterisation facilities across India, the country continues to fall short of achieving international benchmarks for optimal MI care.

Protocol: Faecal microbiota transfer in liver cancer to overcome resistance to atezolizumab/bevacizumab - a multicentre, randomised, placebo-controlled, double-blind phase II trial (the FLORA trial)

Por: Rauber · C. · Roberti · M. P. · Vehreschild · M. J. · Tsakmaklis · A. · Springfeld · C. · Teufel · A. · Ettrich · T. · Jochheim · L. · Kandulski · A. · Missios · P. · Mohr · R. · Reichart · A. · Waldschmidt · D. T. · Sauer · L. D. · Sander · A. · Schirmacher · P. · Jäger · D. · Michl
Introduction

Combined vascular endothelial growth factor/programmed death-ligand 1 blockade through atezolizumab/bevacizumab (A/B) is the current standard of care in advanced hepatocellular carcinoma (HCC). A/B substantially improved objective response rates compared with tyrosine kinase inhibitor sorafenib; however, a majority of patients will still not respond to A/B. Strong scientific rationale and emerging clinical data suggest that faecal microbiota transfer (FMT) may improve antitumour immune response on PD-(L)1 blockade. Early trials in melanoma with FMT and reinduction of immune checkpoint blockade (ICI) therapy in patients with anti-PD-1-refractory metastatic melanoma were reported in 2021 and demonstrated reinstatement of response to ICI therapy in many patients. Due to anatomical vicinity and the physiological relevance of the gut-liver axis, we hypothesise HCC to be a particularly attractive cancer entity to further assess a potential benefit of FMT in combination with ICI towards increased antitumour immunity. Additionally, HCC often occurs in patients with liver cirrhosis, where liver function is prognostically relevant. There is evidence that FMT may increase hepatic function and therefore could positively affect outcome in this patient population.

Methods and analysis

This prospective, multicentre, randomised, placebo-controlled, double-blind phase II clinical trial has been designed to assess immunogenicity and safety of FMT via INTESTIFIX 001 combined with A/B in advanced HCC in comparison to A/B with placebo. Primary endpoints are measured as tumour CD8+ T cell infiltration after 2 cycles of treatment with vancomycin, A/B+INTESTIFIX 001 in comparison to vancomycin-placebo, A/B+INTESTIFIX 001-placebo and safety of the therapeutic combination in advanced HCC. INTESTIFIX 001 is an encapsulated FMT preparation by healthy donors with a high alpha-diversity in their gut microbiome for oral administration, manufactured by the Cologne Microbiota Bank (CMB). Sample size was calculated to achieve a specific expected accuracy for the primary immunological endpoint. 48 subjects will be randomised to reach a goal of 42 usable measurements in the modified intention-to-treat set. Subjects will be randomised in a 2:1 ratio to A/B or placebo (28 A/B, 14 placebo).

Ethics and dissemination

The study was approved by ethics committee review and the German Federal Ministry of Drugs and Medical Devices. The trial is registered under EU CT no. 2023-506887-15-00. The outcome of the study will be disseminated via peer-reviewed publications and at international conferences.

Factors Affecting Sustainable Improvement of Nurses' EBP Competency After Receiving an EBP Training Program: A Mixed‐Methods Study

ABSTRACT

Aim

To explore the factors affecting the sustainable improvement of nurses' evidence-based practice (EBP) competency after receiving an EBP training program.

Design

A sequential mixed-methods study.

Methods

Thirty-seven ICU nurses participated from an adult ICU in Egypt. The qualitative phase used a category-generating approach with focus group interviews and content analysis. The quantitative phase followed a cross-sectional descriptive design using self-report questionnaires. The study adhered to the Good Reporting of a Mixed Methods Study (GRAMMS) guidelines and was registered with ClinicalTrials.gov (NCT05941364).

Results

Qualitative analysis generated six subcategories, organised into three overarching themes: working environment challenges, job dissatisfaction and organisational obstacles. Quantitative findings revealed low levels of motivation (M = 19.1, SD = 2.2, out of 60), self-efficacy (M = 18.4, SD = 8.66) and self-regulation (M = 124.9, SD = 52.6). The highest mean score was observed for the Sustained Implementation Support Scale (M = 94.7, SD = 5.0, out of 140). These variables showed negative correlations with the sustainability gap. Integration of findings through a joint display demonstrated a convergence of results regarding training program burden and low motivation.

Conclusions

Sustaining nurses' EBP literacy requires addressing long-term obstacles such as inadequate job satisfaction, limited workplace support and lack of team cohesion. Sustained organisational support and leadership development are essential for EBP clinical integration.

Implications for Nursing

The study highlights key strategies for nurses' development to enhance care quality, including improving self-efficacy through mentorship and fostering a supportive work environment. Health policies should establish EBP as a core competency, offer flexible schedules, ongoing training, adequate resources, and empower nurse leaders for successful implementation.

Impact

This study addresses the critical challenge of sustaining nurses' competency improvements after EBP training. The findings are crucial for healthcare administrators, policymakers and educators aiming to design effective EBP training programs. By addressing these factors, the study has the potential to improve patient outcomes.

Objective

The emergency department (ED) often serves as a crucial pathway for cancer diagnosis. However, little is known about the management of patients with new suspected cancer diagnoses in the ED. The objective of this study was to explore emergency physicians’ experiences in managing patients with a newly suspected cancer diagnosis in the ED.

Design

Between January and April 2024, we conducted a qualitative descriptive study. Interviews were conducted by trained research personnel using a semistructured interview guide. Interviews were conducted until thematic saturation was achieved. The interview transcripts were coded and thematic analysis was used to uncover key themes.

Setting and participants

Emergency physicians practising in Ontario, Canada.

Results

20 emergency physicians were interviewed. Four themes around the management of patients with new suspected cancer diagnoses in the ED were identified: (1) healthcare system-level factors that impact suspected cancer diagnosis through the ED, (2) institutional and provider-level challenges associated with managing patients with a suspected cancer diagnosis in the ED, (3) patient-level characteristics and experiences of receiving a cancer diagnosis in the ED and (4) the need for care coordination for patients with suspected cancer in the ED.

Conclusions

Physicians experienced several unique challenges in managing patients with a suspected cancer diagnosis in the ED. Overall, the findings of this study suggest these challenges often make the ED a difficult environment in which to deliver a suspected cancer diagnosis.

DXA-derived visceral adipose tissue reference values and metabolic syndrome risk threshold in an Algerian adult population

by Mohammed Hadi Bestaoui, Ali Lounici, Amar Tebaibia, Latifa Henaoui, Nawal Brikci-Nigassa, Houssem Baghous, Amel Bensefia

Background

Visceral adipose tissue (VAT) is associated with several cardiometabolic risk factors, particularly metabolic syndrome and insulin resistance. Reference values for VAT vary across populations, genders, and ages. Data on visceral fat in the Algerian population are lacking. This study aimed to establish reference values for VAT in a general adult population. The secondary objectives were to determine cardiometabolic consequences and to propose suggested threshold values for VAT to predict metabolic syndrome.

Materials and methods

This cross-sectional, analytical study randomly selected participants from the electoral list of Tlemcen, Algeria. VAT was measured using dual-energy X-ray absorptiometry (DXA) General Electric Healthcare© Lunar iDXA.

Results

A total of 301 adults (147 men and 154 women) with a mean age of 49.3 ± 15.1 years participated. The median (25th-75th percentiles) VAT mass was 1364 g (690–2049) in men and 1060 g (585–1590) in women. Binary logistic regression analyses demonstrated that cardiometabolic risk factors, including hypertension, type 2 diabetes, dyslipidemia, metabolic syndrome, insulin resistance according to HOMA2-IR, hepatic steatosis, and sleep apnea syndrome, were significantly dependent on VAT mass. Threshold values for VAT to predict metabolic syndrome (according to International Diabetes Federation) were ≥ 1369 g in men (sensitivity: 86.2%, specificity: 74.2%, Youden’s index: 0.604) and ≥ 1082 g in women (sensitivity: 76.3%, specificity: 76.9%, Youden’s index: 0.532).

Conclusion

This study provides reference values for VAT in an urban Algerian adult population and highlights its importance in assessing cardiometabolic risk.

Introduction

Air pollution is a significant global health concern, with studies from the USA and Europe linking long-term exposure to respiratory issues and poor school attendance in children. While Indian cities experience much higher pollution levels, the impact on lung development in Indian children remains unclear. This study aims to assess the burden of impaired lung function in Indian children and identify key factors contributing to pollution-induced lung injury.

Methods and analysis

This longitudinal, prospective cohort study is conducted in four cities categorised by particulate matter 2.5 (PM2.5) levels: ‘very high’ (Delhi), ‘high’ (Mumbai, Bangalore) and ‘moderate’ (Mysore). A total of 4000 participants (1000 from each city) will be included in the study. Participants will complete a structured questionnaire covering sociodemographics, asthma and allergy history (International Study of Asthma and Allergies in Childhood core questionnaire), dietary intake (24-hour recall and Food Frequency Questionnaire), Physical Activity-C Questionnaire and air pollution exposure. Spirometry and Forced Oscillation Technique will be used to assess lung function. Blood samples will be collected for identification of biomarkers to predict lung impairment. After quality checks, data will be compiled, summarising pulmonary function parameters alongside covariates and confounders. Analysis of Variance (ANOVA) will assess between-city and within-city differences in lung function.

We anticipate a higher prevalence of reduced lung function in children residing in cities with very high and high PM2.5 levels compared with the moderately polluted city. Findings from this study could establish normal age-appropriate lung function reference values for Indian urban children, aiding in clinical diagnosis.If a reliable biomarker for identifying children at risk of lung impairment is available, it could serve as an early predictor of poor lung health in asymptomatic children.

Ethics and dissemination

The approval from individual site institutional review board (IRB) is obtained prior to initiation of the study from institutional ethics committee, St. John’s Medical College and Hospital, Bangalore; institutional ethics committee, JSS Medical College, Mysore; institute ethics committee, Indian Institute of Technology Bombay and institute ethics committee, All India Institute of Medical Sciences. Findings from this study will be disseminated through conference presentations, peer-reviewed publications and establishment of normal age-appropriate lung function reference values for children living in urban India.

Introduction

Sepsis is a major cause of death both globally and in the United States. Early identification and treatment of sepsis are crucial for improving patient outcomes. International guidelines recommend hospital sepsis screening programmes, which are commonly implemented in the electronic health record (EHR) as an interruptive sepsis screening alert based on systemic inflammatory response syndrome (SIRS) criteria. Despite widespread use, it is unknown whether these sepsis screening and alert tools improve the delivery of high-quality sepsis care.

Methods and analysis

The Sepsis Electronic Prompting for Timely Intervention and Care (SEPTIC) master protocol will study two distinct populations in separate trials: emergency department (ED) patients (SEPTIC-ED) and inpatients (SEPTIC-IP). The SEPTIC trials are pragmatic, multicentre, blinded, randomised controlled trials, with equal allocation to compare four SIRS-based sepsis screening alert groups: no alerts (control), nurse alerts only, prescribing clinician alerts only, or nurse and prescribing clinician alerts. Randomisation will be at the patient level. SEPTIC will be performed at eight acute-care hospitals in the greater New York City area and enrol patients at least 18 years old. The primary outcome is the percentage of patients with completion of a modified Surviving Sepsis Campaign (SSC) hour-1 bundle within 3 hours of the first SIRS alert. Secondary outcomes include time from first alert to completion of a modified SSC hour-1 bundle, time from first alert to individual bundle component order and completion, intensive care unit (ICU) transfer, hospital discharge disposition, inpatient mortality at 90 days, positive blood cultures (bacteraemia), adverse antibiotic events, sepsis diagnoses and septic shock diagnoses.

Ethics and dissemination

Ethics approval was obtained from the Columbia University Institutional Review Board (IRB) serving as a single IRB. Results will be disseminated in peer-reviewed journal(s), scientific meeting(s) and via social media.

A qualitative study on barriers and facilitators of COVID-19 vaccination during pregnancy among pregnant women in Malaysia

by Muhammad Hafiz Mohamed Pauzi, Azidah Abdul Kadir, Rosediani Muhamad, Zainab Mat Yudin

Background

COVID-19 vaccination is crucial for pregnant women to protect against severe complications during pregnancy. However, vaccine hesitancy and refusal can affect acceptance rates among this vulnerable group, posing risks to both maternal and fetal health. This research was conducted to explore the barriers and facilitators influencing COVID-19 vaccination among Malaysian pregnant women.

Methods

This qualitative study adopted a hermeneutic phenomenological design. Nineteen pregnant women receiving antenatal care at three clinics in Kelantan between February 2024 and June 2024 were purposively selected to participate in in-depth interviews. The interviews were audio-recorded, transcribed verbatim, and analyzed using NVivo software alongside manual coding. Thematic analysis, incorporating both inductive and deductive approaches, was conducted to identify key themes.

Results

Most pregnant women expressed hesitancy toward COVID-19 vaccination during pregnancy due to various concerns. Our findings identified four key themes as barriers to vaccination: (i) Fear of side effects, (ii) Negative social influences, (iii) Perception of returning to normalcy, and (iv) Vaccine scepticism and prejudice. Conversely, three themes emerged as facilitators of vaccine acceptance: (i) Concerns about the effects of COVID-19 infection, (ii) Trust in the vaccine, and (iii) Personal and shared vaccination experiences.

Conclusion

This study identified key factors influencing COVID-19 vaccine hesitancy. These findings highlight the importance of addressing both personal and social dimensions of vaccine hesitancy. Public health interventions should focus on building trust, countering misinformation, and leveraging positive community experiences to encourage vaccine uptake, particularly in populations where hesitancy remains a concern.

Presymptomatic microRNA-based biomarker signatures for the prognosis of localized radiation injury in mice

by Lucie Ancel, Jules Gueguen, Guillaume Thoër, Jules Marçais, Aïda Chemloul, Bernard Le Guen, Marc Benderitter, Radia Tamarat, Maâmar Souidi, Mohamed Amine Benadjaoud, Stéphane Flamant

The threat of nuclear or radiological events requires early diagnostic tools for radiation induced health effects. Localized radiation injuries (LRI) are severe outcomes of such events, characterized by a latent presymptomatic phase followed by symptom onset ranging from erythema and edema to ulceration and tissue necrosis. Early diagnosis is crucial for effective triage and adapted treatment, potentially through minimally invasive biomarkers including circulating microRNAs (miRNAs), which have been correlated with tissue injuries and radiation exposure, suggesting their potential in diagnosing LRI. In this study, we sought to identify early miRNA signatures for LRI severity prognosis before clinical symptoms appear. Using a mouse model of hindlimb irradiation at 0, 20, 40, or 80 Gy previously shown to lead to localized injuries of different severities, we performed broad-spectrum plasma miRNA profiling at two latency stages (day 1 and 7 post-irradiation). The identified candidate miRNAs were then challenged using two independent mouse cohorts to refine miRNA signatures. Through sparse partial least square discriminant analysis (sPLS-DA), signatures of 14 and 16 plasma miRNAs segregated animals according to dose groups at day 1 and day 7, respectively. Interestingly, these signatures shared 9 miRNAs, including miR-19a-3p, miR-93-5p, miR-140-3p, previously associated with inflammation, radiation response and tissue damage. In addition, the Bayesian latent variable modeling confirmed significant correlations between these prognostic miRNA signatures and day 14 clinical and functional outcomes from unrelated mice. This study identified plasma miRNA signatures that might be used throughout the latency phase for the prognosis of LRI severity. These results suggest miRNA profiling could be a powerful tool for early LRI diagnosis, thereby improving patient management and treatment outcomes in radiological emergency situations.
