To examine triggers, responses, and outcomes for patient-related violence and/or aggression events during acute hospitalisation.
This was a descriptive observational study undertaken at two healthcare organisations.
Pre-existing data were extracted from organisational incident reports and individual medical records during a retrospective period (1/1/2023 to 30/6/2023) and a prospective period (7/6/2024 to 16/11/2024). Violence and/or aggression events requiring an organisational response that involved patients hospitalised in general ward areas at a metropolitan (Site A) and a regional (Site B) site were included. Data were analysed using descriptive statistics and content analysis.
The sample included 100 retrospective cases and 42 prospective cases. The most prevalent causes for hospitalisation related to a medical or mental health condition and dementia. Confusion and irritability were the most common forms of behaviour of concern prior to the event. Physical restraint was utilised more frequently in the prospective period compared with the retrospective period. Chemical restraint was used in approximately half of the cases in both study periods. A form of physical violence was the most prevalent behavioural symptom in both periods, followed by verbal aggression and inability to be re-directed.
Patients with a pre-existing medical condition, confusion and/or dementia are frequently involved in violent and/or aggressive events in ward settings. Physical and chemical restraints are commonly used to manage violence and aggression.
Alternative strategies are needed to manage occupational violence and aggression to minimise the need for physical and/or chemical restraint.
This study addresses a gap in evidence regarding triggers, responses and outcomes for patients exhibiting violence and aggression in ward settings during hospitalisation. Patients with dementia, confusion and irritability frequently exhibit behaviours of concern, exposing healthcare workers to potential physical and psychological harm.

To assess the quality of the Spanish Triage System performed by nurses according to the triage code assigned to each patient and to examine factors associated with the need for re-evaluation after completion of triage.
Retrospective longitudinal observational study.
A retrospective analysis was conducted of patients triaged in the emergency department between 2018 and 2023. Patients triaged by other healthcare professionals and those who did not receive a triage priority level were excluded.
493,211 episodes were analysed. Most were low/intermediate acuity (Level IV 65.4%, Level III 23.9%; Level I 0.1%). Mean time-to-first physician record entry increased as acuity decreased (38 min Level I vs. 81 min Level V), yet recorded time-target compliance was lowest in Levels I–II (23.8% and 14.7%). Re-evaluation occurred more often in high-acuity levels and was independently associated with older age, male sex, lower oxygen saturation and longer emergency department length of stay; compared with Level I, Levels II–III and lower adjusted odds of re-evaluation.
Nurse-led triage demonstrated coherent clinical and operational stratification; however, the lowest recorded time-target compliance in the sickest patients suggests a gap between immediate care and electronic documentation.
Streamline documentation workflows for high-acuity cases and use re-evaluation risk profiles to prioritize monitoring and escalation.
Evidence on nurse-led Spanish Triage System performance and time-documentation quality is limited. Acuity and flow metrics showed expected gradients, but target-time compliance was lowest in Levels I–II; predictors of re-evaluation were also identified. Findings support emergency department nursing, quality improvement and potential benefits for patients attending emergency departments.

To assess the level of alarm fatigue among intensive care unit (ICU), cardiac care unit (CCU) and emergency room (ER) nurses, identify associated demographic and occupational factors, determine the most frequent sources of alarms and evaluate nurses’ psychological reactions to alarms.
A cross-sectional, descriptive–analytical study.
ICUs, CCUs and ERs of six public teaching hospitals affiliated with Tehran and Kashan Universities of Medical Sciences in Iran.
Using a multistage stratified random sampling method, 285 nurses were approached, of whom 260 completed and returned the questionnaires (response rate: 91%). Participants were registered nurses with at least a bachelor’s degree or higher and 3 months of experience in ICUs, CCUs or ERs.
The primary outcome was the level of alarm fatigue measured using the validated Nurses’ Alarm Fatigue Questionnaire. Secondary outcomes included factors associated with alarm fatigue and nurses’ reported psychological responses to frequent alarms.
The mean score of alarm fatigue was 26.4±7.9, indicating a moderate level. After adjusting for confounders and hospital-level clustering using multivariable mixed-effects regression, higher monthly income was significantly associated with lower alarm fatigue (β=–0.15, p=0.03), and nurses working rotational shifts reported significantly higher fatigue compared with those with fixed shifts (β=0.18, p=0.02). Other demographic and occupational factors were not significant. Reported psychological reactions to alarms included indifference (14%), irritability (18%) and anxiety/stress (15%).
ICU, CCU and ER nurses experience a moderate level of alarm fatigue, with income and shift type as independent associated factors. The association between income and alarm fatigue may reflect the role of financial stress as an additional job demand that compounds the burden of frequent alarms, particularly in contexts where low base salaries lead nurses to rely on overtime and multiple shifts. These findings underscore the need for targeted managerial and educational interventions, including shift schedule optimisation and attention to workload-related stressors, alongside alarm prioritisation strategies. Due to the cross-sectional design, causal inferences cannot be drawn.
To develop and user-test a patient decision aid for people diagnosed with degenerative cervical myelopathy and who are considering surgery.
Mixed-methods study describing the development of a patient decision aid.
A draft decision aid was developed by a multidisciplinary steering group (including study authors with degenerative cervical myelopathy, health professionals and researchers) informed by the best available evidence, authorship consensus and existing patient decision aids.
Patient-participants and health professional-participants who manage people with degenerative cervical myelopathy were recruited through social media and the steering group’s research and practice network. Quantitative questionnaires were used to gather baseline data, descriptive feedback, refine the decision aid and assess its acceptability. Qualitative semi-structured interviews were conducted online to gather feedback on the decision aid and were analysed using reflexive thematic analysis.
We conducted 32 interviews: 19 patient-participants and 13 health professional-participants who manage people with degenerative cervical myelopathy (neurosurgeons, neurologists, physiotherapists, orthopaedic surgeons, general practitioners, rehabilitation and pain specialists and consultant occupational physicians and chiropractors). Participants were from 10 countries (Australia, Canada, Cyprus, Germany, Ireland, New Zealand, Sweden, Switzerland, United Kingdom and USA). Most participants rated the decision aid’s acceptability as good-to-excellent and agreed with most aspects of the decision aid (eg, defining degenerative cervical myelopathy, management recommendations, potential benefits and harms, questions to consider asking a health professional).
Our patient decision aid was rated as an acceptable tool by both health professional-participants who treat degenerative cervical myelopathy and patient-participants with lived experience of degenerative cervical myelopathy. This decision aid can be used by clinicians and people with degenerative cervical myelopathy to help with shared decision making following a diagnosis of degenerative cervical myelopathy. A study testing the potential benefits of this decision aid in a clinical setting is recommended.
Language-concordant care, or healthcare in one’s preferred language, is important both for health equity and for improving health outcomes. Linguistic minorities, like Francophones in Ontario, Canada, are at risk of poorer clinical outcomes if they receive non-language-concordant primary care. However, common ratio-based access measures can provide misleading views of minorities’ actual access levels. This cross-sectional geospatial study demonstrates a new way to measure primary care access using average travel time to the nearest five English- and French-speaking family physicians. We also introduce the concept of primary care access fragility, where a region’s primary care access may depend on one or a few local family physicians. Our research question is: are there differences in travel burden and access fragility for census subdivisions (CSDs) across language (English/French), rurality (urban/rural) and region (north/south) in the province of Ontario, Canada?
We conducted a cross-sectional geospatial analysis to estimate English-language and French-language primary care travel burdens and access fragility in Ontario, Canada. We used population and boundary data from Statistics Canada’s 2021 census, road-network data from OpenStreetMaps, and family physician practice locations and language abilities from the College of Physicians and Surgeons of Ontario. We measured travel burden using Valhalla, an open-source road-network analysis platform.
We conducted our analysis for Ontario, Canada’s 577 CSDs, which correspond roughly to municipalities and with populations ranging from 5 inhabitants in Rainy Lake 17B to a high of 2 794 356 in Toronto.
Using public data from January 2026, we identified 15 762 family physicians practising in Ontario, of whom 11.0% reported speaking French. Patient data were obtained from the most recent 2021 census.
Our first primary outcome measures were CSD-level mean travel time to the nearest five English-speaking family physicians, and CSD-level mean travel time to the nearest five French-speaking family physicians, which we compared to explore regional inequities in travel burden. Our secondary outcome measures were based on a novel notion of the travel burden component of ‘primary care access fragility’. This metric indicates how dependent a region’s access is on a small number of local physicians and is defined as the difference between the CSD-level mean travel time to the nearest one physician and to the nearest five physicians. As the difference in travel times grows, so too does access fragility.
Median differences in French-language and English-language travel burdens were strongly significant across rurality, regions and overall (median difference 13.4 min, p
Compared with the general public, Ontario’s French-speakers face higher travel burdens to language-concordant family physicians and higher access fragility, especially in rural and northern regions. Our results are of interest to policymakers and health-system planners, and our methods are applicable to other populations and regions.
To develop and evaluate an explainable machine learning framework enhanced with synthetic data generation to predict unplanned 30-day hospital readmissions among patients with chronic obstructive pulmonary disease (COPD), heart failure (HF) and type 2 diabetes mellitus (T2DM), and to identify key clinical and social predictors of readmission.
A retrospective cohort study using electronic health record data incorporating both structured variables and information extracted from unstructured clinical notes. Synthetic data were generated using advanced resampling and deep learning-based techniques to address outcome imbalance and improve model training.
Intensive care unit and general ward admissions at a single tertiary academic medical centre included in the MIMIC-IV (Medical Information Mart for Intensive Care IV) database.
Adult patients (≥18 years) were admitted with a primary diagnosis of COPD (n=14 050), HF (n=7097) or T2DM (n=12 735) between 2008 and 2019, with complete 30-day follow-up and no in-hospital mortality during the index admission.
The primary outcome was unplanned all-cause hospital readmission within 30-days of discharge. Predictors were drawn from six domains, including demographics, comorbidities, clinical acuity, therapies, behavioural factors and care continuity. Predictive performance was evaluated using multiple machine learning methods and fivefold cross-validation, with model interpretability assessed using established goal and local explanation approaches.
Ensemble-based machine learning models demonstrated the strongest predictive performance across all three disease cohorts. Key predictors of readmission included higher illness severity, greater comorbidity burden, medication non-adherence, gaps in preventive care and limited social support. Models incorporating synthetic data augmentation showed improved discrimination compared with models trained on original data alone.
An explainable synthetic-data driven framework incorporating clinical, behavioural and social data can support prediction of 30-day readmissions among patients with common chronic conditions using routinely available electronic health record data.
Overweight and obesity are a growing global public health problem. Eating behaviours of adults and children are largely influenced by the home food environment (HFE). The lack of access to nutritious food in homes contributes to unhealthy dietary habits and, consequently, overweight and obesity among adults and children, as well as chronic diseases associated with poor diets. The present systematic review aims to identify existing HFE and household food security interventions and to determine the effects of these interventions in improving the availability of healthy food in the home, household access to food, diet quality and nutritional status of adults.
This systematic review protocol was developed according to the Preferred Reporting Items for Systematic reviews and Meta-Analysis protocols guidelines. Electronic databases including PubMed, Web of Science, Scopus, Science Direct and CINAHL (EBSCOhost) will be searched for relevant articles using keywords and MeSH terms. Risk of bias will be assessed using the adapted Cochrane effective practice and organisation of Care risk of bias tool for studies with a separate control group and Risk of Bias in non-randomised studies of interventions. The overall strength of the evidence for each outcome will be assessed using the Grading of Recommendations Assessment, Development and Evaluation tool. Two reviewers will independently screen the identified records and assess the eligible full texts for inclusion. Any discrepancies will be resolved through consensus or consultation with a third reviewer. Where sufficient homogeneous data are available, subgroup analysis will be conducted to explore heterogeneity. A thematic synthesis will be performed for qualitative studies.
This study has a systematic review and meta-analysis design, which will assess published data and does not require ethical approval. Findings of the systematic review will be disseminated through peer-reviewed publications and conference presentations.

Poststroke motor dysfunction places a heavy burden on individuals and society. Virtual reality (VR) offers enhanced motor skill transfer and active rehabilitation by overcoming the scenario-specific constraints of conventional therapies. Validating the efficacy of VR rehabilitation could lead to scalable and cost-effective solutions, potentially enabling home-based rehabilitation. However, the widespread clinical application remains constrained by the lack of rehabilitation-specific VR and multidimensional quantitative assessments. The aim of this study was to investigate the multidimensional effects and neural mechanisms of VR rehabilitation in poststroke motor recovery.
This study is a prospective, randomised, controlled clinical trial protocol designed to evaluate the effects of multisensory VR training on motor dysfunction in patients who had a stroke using multidimensional assessments. The trial consists of a baseline assessment, a 4-week intervention period and an endpoint assessment. A total of 40 patients who had a stroke will be randomly allocated in a 1:1 ratio to either a VR combined with treadmill group or a treadmill-only group. The primary outcome measure is the Fugl-Meyer Assessment of Lower Extremity score, while secondary outcomes include three-dimensional gait analysis, the Berg Balance Scale score, the activities of daily living score and functional near-infrared spectroscopy results. Safety will be evaluated by monitoring the incidence of adverse events. This study aims to determine whether VR rehabilitation offers superior efficacy in improving motor function in patients who had a stroke by using a multidimensional assessment approach, including neural coupling function, muscle movement mechanics and clinical performance. The findings will provide robust, high-quality evidence to support the broader application of VR in clinical practice.
The trial was approved by the Ethics Committee of the First Affiliated Hospital of Chongqing Medical University (2022–155). This study protocol was registered with the clinicaltrials.gov (NCT06275516). The results will be published in a peer-reviewed journal or presented at a conference.
To examine workplace experiences, perspectives on coming out at work, organisational climate and mental health status of lesbian, gay, bisexual, transgender, queer/questioning and other sexual, and gender minority healthcare providers (LGBTQ+ HCPs) within an East Asian cultural context.
Observational, cross-sectional study.
An online cross-sectional survey was conducted among 173 Taiwanese LGBTQ+ HCPs between May and August 2024.
Most of the 173 respondents did not disclose their LGBTQ+ identities to any colleagues, and approximately two-fifths met the clinically significant threshold for depressive symptoms. Furthermore, compared to LGBTQ+ HCPs who disclosed to all, most, about half or a few colleagues, those who had not disclosed to any colleagues reported higher levels of depressive symptoms, lower self-esteem, less comfort with disclosure, greater perceived necessity to conceal their LGBTQ+ identities, lower scores for job stability or security, poorer interpersonal relations and lower agreement that an LGBTQ+-inclusive workplace climate would influence their willingness to remain in their current jobs. Although approximately 80% of the LGBTQ+ HCPs reported that they were familiar with national workplace antidiscrimination laws and that their organisations had grievance mechanisms, nearly two-fifths did not trust the grievance systems or procedures within their organisations.
Results emphasise the urgent need to create an LGBTQ+-inclusive workplace environment with clear and enforceable antidiscrimination policies and inclusive organisational practices to improve both disclosure safety and mental health outcomes for LGBTQ+ HCPs.
The study results extend existing knowledge by identifying the relationship between different levels of disclosure and mental health status among LGBTQ+ HCPs. They also highlight the importance of establishing support groups, a comprehensive mental health referral system and enforcement mechanisms that safeguard legal rights without compromising the privacy or safety of LGBTQ+ HCPs.

Xylella fastidiosa (Xf) is an insect-transmitted, xylem-limited bacterial plant pathogen that infects hundreds of plant species. This pathogen causes bacterial leaf scorch in southern highbush blueberry (Vaccinium corymbosum interspecific hybrids) in the southeastern United States, a disease that has not yet been reported elsewhere. Previously, a comparative genomic analysis of Xf and ancestral host species identified evolutionary events of gene gain and loss related to host range specificity. Here, by using a similar workflow, we identified two loci that are significantly found in blueberry-infecting strains. Locus_1088 included a hypothetical protein and a small part of the N-terminus of an orphan RelE toxin, while Locus_2741 was annotated as a hypothetical protein. Using a protocol based on natural competence, mutants were generated in three Xf subsp. multiplex strains from blueberry. Less biofilm, more planktonic growth, and increased twitching motility as compared to its wild-type (WT) were observed for the strain LA-Y3C_1088 mutant. In blueberry virulence assays, the LA-Y3C_1088 mutant caused significantly more severe symptoms than LA-Y3C_WT, whereas no significant differences were observed for other mutated strains. Interestingly the mutation of Locus_1088 additionally disrupted a toxin (part of a toxin-antitoxin system) that is likely responsible for the phenotypic changes observed. However, because the two independent mutants were not generated, we could not determine whether the phenotype resulted from disruption of hypothetical protein or the toxin. Additionally, since the coffee-isolated but never tested in blueberry Xf subsp. fastidiosa strain CFBP8073 was found to encode the two blueberry-associated loci studied here, its virulence was assessed in blueberry. This strain caused severe symptoms comparable to the control strain AlmaEm3 from blueberry. Due to the complexity of understanding host specificity in Xf, any advance in identifying genetic markers for host specificity in this devastating pathogen could greatly improve management of Xf worldwide.by Sudim Sharma, Anjali Neupane, Dikshya Kandel, Pratibha Chalisay, Sabina Marasini, Budhi Setiawan, Deepak Chandra Bajracharya, Shyam Raj Upreti, Leela Khanal, Haruko Yokote, Chahana Singh, Kshitij Karki
BackgroundHome-Based Records (HBRs) are personal health documents intended to improve continuity of care and caregiver engagement across reproductive, maternal, newborn, and child health (RMNCH) services. In Nepal, both standalone (sHBR) and integrated (iHBR) models are implemented, yet comparative evidence on their utilization and implementation challenges is limited. This study examined utilization patterns and system-level barriers associated with sHBR in Madhesh Province and iHBR in Koshi Province.
MethodsWe conducted a comparative qualitative study with descriptive quantitative profiling between May 17 and August 27, 2024. A total of 100 semi-structured in-depth interviews were completed with caregivers, health workers, Female Community Health Volunteers, and program managers across two provinces. The study applied “kuragraphy,” an ethnographic approach integrating interviews and field observations to construct contextual case narratives. Socio-demographic data were analyzed descriptively using the statistical package for the social Sciences (SPSS). Informed by the Human Centered Design (HCD) approach, the qualitative data were thematically analyzed in Excel using the Journey to Health and Immunization (JTHI) framework.
ResultsCaregivers widely perceived HBRs as essential documents, primarily for immunization tracking and future service access. The iHBR was viewed as more comprehensive and user-friendly, particularly due to its illustrations, which improved comprehension among low-literacy users. However, understanding remained limited among illiterate and marginalized populations. Family involvement in record management was minimal and largely confined to mothers. Implementation barriers included inadequate training – particularly for iHBR use, limited decision-making authority among frontline health workers, incomplete documentation of non-immunization components, poor material quality of sHBR, and concerns regarding the sustainability of donor-supported iHBR initiatives.
ConclusionHBR utilization in Nepal is shaped by caregiver literacy, gender dynamics, and health-system readiness. Strengthening training, supportive supervision, user-centered design, and sustainable supply mechanisms will be essential to optimize HBR effectiveness and support equitable RMNCH service delivery.

Equine asthma is a chronic, non-infectious inflammatory disease of the lower airways in horses, classified as mild to moderate (MEA) or severe (SEA). Its pathogenesis is not fully understood and is influenced by environmental and seasonal factors. In this cross-sectional study, seasonal effects on the bronchoalveolar lavage fluid (BALF) metabolome were investigated in asthmatic and non-asthmatic horses. The metabolome of 230 BALF samples from horses across different seasons, classified as cytologically unremarkable (CUA), MEA, or SEA, was analyzed using proton nuclear magnetic resonance spectroscopy (1H-NMR). Principal component analysis was performed for each season, and metabolite profiles were statistically compared between seasons within each group. Altered metabolites were subjected to pathway enrichment analysis using the FELLA R package. Asthmatic horses showed significant seasonal changes in metabolite concentrations between warm and cold seasons, whereas only trends were observed in CUA horses. Pathway analysis indicated enrichment of cholesterol metabolism across all groups. The mTOR signaling pathway was only enriched in SEA horses. Several metabolites—including valine, taurine and carnitine —were altered during the transition from winter to spring in asthmatic horses. These findings indicate that the winter to spring transition significantly modulates the airway metabolome in asthmatic horses, particularly in SEA-affected animals.by Tadgh Connery, Sofija Kukulite, Conor Farrell, Rosa Horgan, Karen Barry, Megan Doyle, Annalisa Setti, Mike Murphy
BackgroundDeath anxiety is fast becoming recognised as a transdiagnostic construct across myriad mental health conditions. Though existing clinical treatments of death anxiety, such as Cognitive Behaviour Therapy type interventions, have been shown to be effective, Terror Management Theory (TMT) proposes self-esteem as a protective factor against death anxiety by endowing individuals with a feeling of significance in life and helping them to process the nature of death and its inevitability. Despite the centrality of self-esteem to TMT, however, extant research examining its relationship with death anxiety has yet to be synthesised. The current study aims to systematically review peer-reviewed, quantitative research examining the association between death anxiety and self-esteem and, where possible, to test the strength of these associations through meta-analysis.
MethodA systematic search of quantitative and mixed-methods studies will be conducted across six databases: MEDLINE; PsycINFO; PubMed; Web of Science; CINAHL and; EMBASE. Google Scholar will also be searched and the first 200 records by relevance will be screened for eligibility. Searches will be conducted by TC, and records will be screened by TC, SK, CF, RH and KB, so that each record is screened for eligibility by at least two authors. Data extraction and quality assessment, using the Joanna Briggs Inventory Risk of Bias tools, will be performed by TC, SK, CF, RH and KB, so that each record is assessed by at least two authors, with doubts and discrepancies being resolved through discussion with AS and MM. A narrative synthesis of relevant data will be presented and, where sufficient data are available, meta-analysis will be conducted using the MAJOR extension for Jamovi to establish an overall effect size for the association between death anxiety and self-esteem. Should sufficient data be available, demographic factors, such as gender and age, and clinical population status (clinical vs. non-clinical population) will be examined as moderators of the effect. This protocol was developed in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and has been registered in PROSPERO (CRD42024591775).
DiscussionThe current review will systematically examine the relationship between death anxiety and self-esteem. Should sufficient data be available, an overall effect size of the relationship will be generated. By better understanding how death anxiety is related to self-esteem, and by establishing the size and significance of the relationship will aid firstly in systematically validating TMT and, secondly, identify whether self-esteem may be targeted in future death anxiety interventions to reduce death anxiety and improve individuals’ overall mental health.

Municipal government officials (MGOs) have played key roles in managing decontamination project of radioactive materials in the aftermath of the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident. However, the subjective distress experienced by MGOs during the decontamination project, mainly stemming from challenges in coordination with the national government, is not yet fully documented. The purpose of this study is to descriptively understand the nature and causes of subjective distress among MGOs and to make an exploratory conceptual model of the process through which such subjective distress becomes manifest. Narratives from three MGOs were collected through interviews and subjected to qualitative analysis using the Steps for Coding and Theorisation method. For the first purpose, the results indicate that inconsistencies in national reconstruction and decontamination designs impose substantial burdens at the operational level; these burdens are further amplified by inadequate management by national authorities, and subjective distress emerges through a breakdown of trust among national government officials, municipalities, and residents. For the second purpose, an exploratory conceptual model explaining the progression toward subjective distress through the following four stages was created: the emergence of distrust and adversarial orientations toward the national government, the dilemma of occupying an intermediate position, the erosion of ties with residents, and the threat to professional pride. Overall, through experiences such as questioning the national government’s reconstruction policies, enduring the psychological burden of occupying an intermediate position, and witnessing a breakdown in trust with residents, MGOs may find their professional pride undermined; consequently, subjective distress, manifesting as a profound sense of emptiness, may arise. As MGOs are likely to stand at the frontline of managing post-radiation-disaster reconstruction and decontamination efforts, it is essential to develop protective measures for their mental health from both macro-level, organisational perspectives and micro-level, occupational and psychological perspectives.by Makiko Sasaki, Mamoru Tanaka, Akihiro Nomoto, Ryusei Yamasaki, Tomokazu Yoshimura, Shigenobu Yano, Yasunari Sasaki, Yuki Kojima, Taketo Suzuki, Hirotada Nishie, Keiji Ozeki, Takaya Shimura, Eiji Kubota, Hiromi Kataoka
Photodynamic therapy (PDT) is an anti-cancer therapy that employs a photosensitizer (PS) and an optimal wavelength of light, causing a photochemical reaction that releases reactive oxygen species, thereby inducing cancer cell death via oxidative stress. Because light irradiation is limited to the tumor site, PDT has minimal adverse effects. The cancer cell selectivity of the PS is important for reducing damage to the normal mucosa caused by scattered light. Antibody-drug conjugates (ADC) are novel anti-cancer therapies that combine a monoclonal tumor-surface-receptor-targeting antibody with a drug bonded through chemical linkers. ADCs enable the targeted delivery of a variety of drugs to cancer cells while minimizing their delivery to healthy tissues. One such tumor surface receptor is the human epidermal growth factor receptor 2 (HER2), which is of interest in the treatment of many cancers, including gastrointestinal cancer. To improve tumor selectivity and minimize damage to the mucosa surrounding the tumor in PDT, we established a novel PS glucose-linked chlorin e6-conjugated trastuzumab (G-Ce6-trastuzumab) that is conjugated to existing PS glucose-linked chlorin e6 (G-Ce6) and evaluated its anti-cancer effect compared to G-Ce6. The effect of PDT was evaluated using HER2-high-expression cells NCI-N87 and HER2-low-expression cells MKN-45. G-Ce6-trastuzumab is internalized by the intracellular organelles in cancer cells. Evaluation of cell death using the WST-8 assay also demonstrated a significantly higher cytotoxic effect of G-Ce6-trastuzumab in HER2-high-expression cells compared with conventional PS G-Ce6. Thereby, G-Ce6-trastuzumab may be an excellent novel PS for PDT because of its strong selectivity for HER2-high-expression cells.by Verner N. Orish, Renosten E. Tetteh, David Adzah, Chinecherem A.

BackgroundToxoplasma gondii (T. gondii) is a successful protozoan parasite infecting up to a third of the human population. It has varied transmission routes including ingestion of food and water contaminated by cat feces containing oocysts of the parasite and ingestion of bradyzoites in poorly cooked meat. Blood transfusion is another possible route of transmission especially among people with medical conditions requiring blood transfusion, such as those with sickle cell disease (SCD). This study aimed at finding out the prevalence of T. gondii infection and the association of blood transfusion among patients with SCD.
MethodThis study was a cross-sectional study involving SCD patients attending the SCD clinic at the Ho Teaching Hospital in the Volta Region of Ghana. Questionnaire administration was employed to obtain sociodemographic information, cat ownership, consumption of poorly cooked meat, as well as blood transfusion history. A blood sample was collected and anti-T. gondii IgG and IgM were detected using Rapid Diagnostic Test (RDT), while Enzyme-linked Immunosorbent Assay (ELISA) was used as the gold standard and reference. Seropositivity was defined as either positive for IgG, IgM or both. Data was analyzed using SPSS version 23, with frequency distribution done for the sociodemographic variables and the prevalence of RDT and ELISA anti-T. gondii IgG and IgM. Pearson Chi-square analysis was performed to find any significant association between diagnosis of T. gondii infection with sociodemographic variables and blood transfusion. Logistic regression analysis was performed to investigate the odds of seropositivity (ELISA) with sociodemographic variables and blood transfusion.
ResultsA total of 156 SCD patients participated in this study of which 124 (79.5%) and 32(20.5%) were HbSS and HbSC respectively. Among the study participants, 105 (67.3%) had a history of blood transfusion. A total of 60 (38.5%) and 83 (53.2%) patients were positive for RDT and ELISA respectively. No significant association was seen between T. gondii diagnosis and cat ownership (RDT,20[37.7%], p = 0.891; ELISA, 27[50.9%], p = 0.673) and consumption of poorly cooked meat (RDT,37[41.6%],p = 0.370;ELISA,53[59.6%], p = 0.211). However there was a significant association between T. gondii diagnosis and age, with seropositive results predominantly seen among older patients (≥20 years) (RDT, 38[52.1%], p = 0.002; ELISA 49 [67.1%, p = 0.002]. Blood transfusion had a significant association with T.gondii diagnosis (RDT, p = 0.003; ELISA, p = 0.001). A total of 66 (62.9%) of SCD patients who had history of blood transfusion tested positive for ELISA and they had 3 times the odds of testing positive for ELISA (adjusted OR 3.14[95% CI 1.50–6.58]; p = 0.002).
ConclusionThe prevalence of T. gondii infection was higher by ELISA (53.0%) than by rapid diagnostic testing (RDT) (38.5%), and sickle cell disease patients with a transfusion history had higher odds of seropositivity. These findings highlight the need to strengthen transfusion safety protocols and consider screening strategies for T. gondii among high-risk populations such as patients with sickle cell disease. Also, there is the need for longitudinal research to help elucidate the true contribution of blood transfusion transmission of T. gondii since a cross-sectional study, causality could not be established.

Hepatocellular carcinoma (HCC) has a very significant mortality rate and is one of the most common cancers worldwide. Jacaranda mimosifolia is reported to have potential antitumor activities against various human cancers. However, the effects of J. mimosifolia on HCC are yet elusive. This study aimed to investigate the anti-HCC potential of methanolic extract of J. mimosifolia leaves using in vitro and in vivo studies and a network pharmacology approach. The effect of J. mimosifolia extract was assessed on Huh-7.5 cells using MTT assay, wound healing assay, and DNA fragmentation assay. These experiments found that J. mimosifolia extract significantly suppressed Huh-7.5 cell proliferation, impaired cell migration, and induced cell apoptosis. The real-time PCR validated the upregulation of p53 and Bax, alongside the downregulation of AFP and GPC3 in Huh-7.5 cells after treatment with J. mimosifolia extract. In vivo experiments confirmed the hepatoprotective effects of J. mimosifolia extract in mice models with CCl4-induced hepatic injury. In addition, through network pharmacological analysis, J. mimosifolia was found to play a critical role against HCC via targeting multiple potential targets and pathways. Docking analysis identified apigenin and kaempferol with the lowest binding energy against PTGS2 and EGFR, respectively, while flavonol glycoside showed the lowest binding energy against MMP9. However, detailed research is needed to isolate the potential phytochemicals from J. mimosifolia against HCC.by Sandra A. Allan
Cornsilk flies, Euxesta eluta and Chaetopsis massyla (Diptera: Ulidiidae), are serious economic pests affecting sweet corn production in Florida. As a basis for development of enhanced trapping strategies, the sensory and behavioral basis for response to color was examined. Using electroretinograms, spectral sensitivity curves for both species revealed broad curves with a peak in the UV (350 nm) and the green region (500–550 nm) of the spectrum. Curves for males and females of each species were relatively similar in shape. Using pigment templates, the measured curve for E. eluta was matched by pigment combinations with maximum sensitivity at 350, 430, 500 and 560 nm in a ratio of 25:21:25:29. Similarly, the curve for C. massyla was best matched by pigments with maximum sensitivity at 350, 430, 500 and 560 nm in a 28:18:27:27 ratio. Laboratory behavioral assays were conducted to evaluate if attraction occurred in response to the color or the brightness of a target. Attraction responses were evaluated in paired tests to blue, green and yellow cards paired with gray cards of matching brightness. Despite relatively similar visual pigments, the two species differed greatly in their behavioral attraction. Euxesta eluta was only attracted to yellow cards at low or high brightness levels, to mid-level bright blue cards and not attracted to green cards at any brightness level. In contrast, C. massyla was highly attracted to yellow and green cards compared to gray cards of the same brightness but avoided blue cards. These differences in response to color and brightness are important for interpretation of surveillance results as well as development visual traps targeted for these species.To estimate the proportion of Italian nurse managers (NMs) intending to leave (ITL) their positions and to identify associated socio-demographic, job-related, and psychosocial factors.
Cross-sectional study.
Between September and November 2023, 464 NMs from 19 public hospitals completed a case-report form and the short version of the Copenhagen Psychosocial Questionnaire II (COPSOQ II). Latent Class Analysis (LCA) identified ITL profiles, and multiple logistic regression assessed factors associated with ITL.
284 NMs (61.2%; 95% CI 57–66) reported an intention to leave within 12 months. LCA identified two classes: (1) Low-ITL (54%)—mainly outpatient NMs from Central regions with strong relationships with management, good support, work–life balance, and autonomy (55.9% probability of being unlikely to leave). (2) High-ITL (46%)—mainly surgical or critical-care NMs, often from Northern regions, marked by poor management relations, low support and high work–family conflict (80.9% probability of being likely to leave). Multiple regression confirmed that stronger management relations reduced ITL (OR 0.60, 95% CI 0.46–0.79) whereas high job demands and work–health conflict increased it (OR 1.56, 95% CI 1.19–2.04). Northern location also predicted higher ITL (OR 1.58, 95% CI 1.03–2.44). Demographics, education, and clinical setting were not significantly associated.
These findings suggest that healthcare organizations should prioritize managerial and organizational strategies targeting modifiable work-related factors to reduce nurse managers' intention to leave. Interventions aimed at improving organizational support, work environment, and job satisfaction may contribute to workforce retention at the managerial level. Future research should evaluate the effectiveness of targeted organizational interventions in sustaining nurse manager retention.
Evidence-Based Practice (EBP) is essential to healthcare quality and safety, integrating scientific evidence with clinical expertise and patient preferences. Despite its importance, EBP implementation still faces major challenges. Educational interventions have proven effective in strengthening EBP competencies among healthcare.
To evaluate the impact of a personalized educational intervention on EBP competencies among healthcare professionals. Working at a private tertiary general hospital, comparing performance before and after the intervention.
A randomized controlled trial involving healthcare professionals was conducted. Eligible and consented participants were randomly assigned to either an Intervention Group (IG) receiving an Evidence-Based Practice (EBP) course or a Control Group (CG) not receiving the course, stratified by job level, role, and work shift. From the completers, 18 participants were randomly selected for the IG, and all 7 available CG participants were included in the final sample for analysis. All study participants completed two validated instruments: the Assessing Competencies in Evidence-Based Medicine (ACE) and the Fresno Test. The educational intervention consisted of a seven-week course with weekly three-hour sessions, for a total of 21 h. Comparative analyses were conducted using a Linear Mixed Model, adjusted for educational level, job level, time working at the hospital, and weekly workload.
A statistically significant increase in general EBP knowledge was observed in the IG following the intervention, with a mean gain of 19.1%. Separate analysis showed improvements of 10.8% in ACE and 24.2% in Fresno Test scores. No statistically significant changes were observed in the CG. Furthermore, after the intervention, the IG outperformed the CG for both general EBP knowledge and Fresno Test scores on both pre- and post-intervention comparisons.
The educational intervention had a positive statistically significant impact on EBP knowledge and skills among healthcare professionals in the IG compared to the CG. These findings underscore the potential of structured educational initiatives to enhance the quality of clinical practice through improved EBP competencies.
