To identify and differentiate workload patterns across shifts and to provide evidence for optimizing nursing workforce allocation in emergency departments:
A cross-sectional study.
Real time data were collected from an emergency department in a general hospital in Seoul, South Korea, between October 30, 2023 to October 24, 2024. Smartphones, beacons, and smartwatches were used to capture nursing time, physical activity, work-related characteristics, and location transitions across 238 shifts. A multiclass eXtreme Gradient Boosting model was developed and evaluated to classify working shifts (day, evening, night). Shapely Additive exPlanations were applied to identify key contributing features, and shift-specific differences were examined using analysis of variance with post hoc tests.
The model demonstrated strong performance in distinguishing shifts. Key features included the number of admissions, discharges, assigned patients, and both direct and indirect nursing time, all of which varied across shifts. In contrast, location transition patterns were relatively consistent.
Shift-specific nursing workloads in emergency departments can be effectively identified using multidimensional, real-world nursing activity data.
Findings support the development of staffing strategies that account for variation in workload across shifts, with potential to improve efficiency and maintain quality of care.
This study addresses the lack of objective evidence for shift-specific workload differences in emergency nursing. It demonstrates that multidimensional activity data can distinguish workload patterns across shifts. The findings may inform staffing decisions for emergency department nurses and support improvements in workforce management and patient care.

To systematically map the landscape of central venous access device research from 2014 to 2024, identifying critical gaps in evidence that may impact nursing practice and patient outcomes across the full device lifecycle from selection through to removal.
This review was conducted in accordance with the Guidance for producing a Campbell evidence and gap map and reported following Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines.
PubMed, Cumulative Index to Nursing and Allied Health Literature Complete, Scopus, and Cochrane Central Register of Controlled Trials were systematically searched with additional hand-searching of reference lists from included reviews.
We systematically reviewed literature published between 2014 and 2024, mapping 710 studies on central venous access device interventions and outcomes. Studies were categorised by design, population, setting, device characteristics, intervention types, and outcomes. Evidence was evaluated using the National Health and Medical Research Council levels of evidence framework.
Of 710 included studies, 89 were systematic reviews and 621 primary studies, of which 41.1% (n = 292) were randomised controlled trials. Research was primarily conducted in high-income countries (n = 405, 65.2%) and focused on adults (n = 370, 59.6%) in hospital inpatient settings (n = 588, 94.7%). Catheter insertion and infection prevention dominated the evidence base, while device selection and removal procedures were less studied. Infection outcomes were extensively reported (bloodstream infection: n = 455, 13.6% of 3349 outcomes), while patient-reported outcomes (n = 218, 6.5%) and cost (n = 60, 1.8%) were underrepresented.
This review reveals that central venous access device research is predominantly focused on insertion and infection prevention while other key parts of nursing practice are under-supported.
Future nursing research should address these gaps to improve evidence-based care across diverse populations and healthcare contexts, particularly focusing on understudied device types, settings, and vulnerable populations.
This review was conducted and reported in accordance with the Guidance for producing a Campbell evidence and gap map.

To explore surrogate decision-making practices regarding end-of-life care for people with dementia in Korean long-term care hospitals from the perspective of healthcare providers.
A qualitative descriptive study.
The data were collected through individual semi-structured interviews with 24 healthcare providers (physicians, oriental medicine doctors, registered nurses and social workers) involved in dementia end-of-life care in their current long-term care hospitals in South Korea. The data were analysed using a conventional content analytic technique.
The analysis yielded three categories and nine subcategories describing surrogate decision-making practices regarding end-of-life care for people with dementia: (a) typical circumstances of end-of-life care planning, (b) expected roles of key personnel and related challenges and (c) important considerations. Participants discussed available treatment options within long-term care hospitals and the potential transfers to acute care hospitals during admission and periods of health decline. Physicians typically led such end-of-life care planning, with nurses playing a supportive role and family members making the final decisions. However, they faced challenges in performing their roles. In end-of-life care discussions, participants weighed the patients' autonomy and best interests alongside family members' interests and other external concerns such as potential lawsuits and insufficient medical resources.
Surrogate decision-making regarding end-of-life care in the context of dementia within long-term care hospitals is considerably complex and challenging for healthcare providers, requiring multifaceted institution-sensitive support.
The study findings suggest the need for targeted education and training to enhance healthcare providers' competencies in end-of-life care discussions, advance care planning and the development of policies and regulations supporting end-of-life care-related practices within long-term care hospitals.

African swine fever (ASF) is a lethal disease of swine that has spread across Asia since its introduction in 2018. South Korea first reported the disease in September 2019 in domestic pigs, and since then, more than 4,000 cases have been reported in wild boars during its expansion up to August 2024. Due to the high number of ASF notifications in wild boars in South Korea, contrasted with their scarcity in most Asian countries, analyzing the spatiotemporal spread of the disease in a setting with active surveillance provides valuable insights. In this study, we performed a trend-surface analysis on temporally gridded case data to characterize the overall geographic spread and direction of ASF in wild boars across South Korea, from its emergence to August 2022. Additionally, we propose a novel approach distinct from previous studies, to estimate spread velocity by incorporating an upper threshold to avoid unrealistic values. The model described the spread of ASF in the study area. The disease showed greater expansion in the east of the country. Initially, a south and eastward direction was estimated. The estimated median velocity was 19.53 km/month, with cell-level velocities ranging from 2.45 to 69.99 km/month. Velocity increased notably from autumn 2021 onward and varied substantially across years. Our results show the dynamics of ASF in wild boars of South Korea, providing new evidence of their role in the epidemiology of the disease.Hyperbaric oxygen therapy (HBOT) enhances wound healing by promoting angiogenesis and reducing hypoxia. However, the role of air-breaks—intermittent exposures to ambient air during HBOT—remains unclear. We investigated the effects of air-breaks on HBOT-mediated wound healing, particularly in combination with adipose-derived stromal cells (ASCs). Full-thickness wounds were created in C57BL/6 mice (n = 36) and assigned to control, HBOT (1 h/day, 2 ATA for 11 days), or HBOT with a 10-min air-break groups. In a second experiment, we evaluated ASC treatment combined with HBOT and air-breaks. Wound healing was assessed via gross examination, histology and gene expression analysis of collagen type 1 alpha 1 (Col1a1), hypoxia-inducible factor 1 alpha (Hif1a) and tumour necrosis factor (Tnf-α). Compared with HBOT alone, air-breaks significantly improved wound closure, epithelial regeneration and collagen deposition (p < 0.05). Gene analysis showed higher Col1a1 expression and lower Hif1a and Tnf-α levels in the air-break group. In ASC-treated wounds, air-breaks further accelerated healing, enhancing collagen synthesis and reducing hypoxia and inflammation. These findings suggest that incorporating air-breaks into HBOT protocols improves wound healing outcomes, both generally and in ASC-based therapies, by modulating collagen production, hypoxia and inflammation, and could optimise HBOT efficacy, particularly in cell-based regenerative therapies.
To investigate the relationship between nurse managers' authentic leadership and staff nurses' organisational citizenship behaviour and to explore the mediating roles of different types of organisational silence in the relationship.
A cross-sectional, correlational, descriptive design.
Survey data from 216 nurses across five hospitals in South Korea were utilised. We used structural equation modelling to examine the relationships between authentic leadership, organisational silence and organisational citizenship behaviour.
Authentic leadership was positively associated with organisational citizenship behaviour and prosocial silence and was negatively associated with acquiescent and defensive silence. Acquiescent silence negatively impacted organisational citizenship behaviour, whereas prosocial silence had a positive effect. Defensive silence showed no significant relationship with organisational citizenship behaviour. Authentic leadership's indirect effects on organisational citizenship behaviour were mediated by acquiescent and prosocial silence.
Nurse managers' authentic leadership enhances organisational citizenship behaviour by reducing acquiescent and defensive silence and fostering prosocial silence. Although prosocial silence promotes harmony and collaboration, nurse managers must also encourage open communication to maintain a positive and professional organisational culture.
Developing authentic leadership in nurse managers can improve nurses' organisational citizenship behaviour by addressing organisational silence, thereby creating a supportive and efficient healthcare environment that benefits staff as well as patients.
No patient or public contribution.
Authentic leaders serve as positive role models who can improve employees' organisational citizenship behaviour by reducing negative forms of organisational silence. However, the mediating effect of organisational silence on the relationship between authentic leadership and organisational citizenship behaviour may vary depending on the type of silence, as different types are induced by distinct underlying motivations. Understanding these dynamics can inform strategies to improve nurses' workplace interactions and patient care outcomes.

Whereas diabetes-related stigma is increasingly recognized as a barrier to diabetes management, little is known about this social phenomenon in collectivist African settings. The purpose of this study was to examine diabetes-related stigma among adults with type 2 diabetes (T2D) in Ghana, highlighting behavioral and psychological mechanisms underpinning the impact of stigma on hemoglobin A1C.
Cross-sectional analytical design.
Adults with T2D (n = 190), seeking care at a tertiary hospital in Ghana, were recruited. A battery of questionnaires assessing psychological (diabetes-related stigma, depression, anxiety, diabetes distress) and behavioral constructs (diabetes concealment and diabetes self-management) were administered. Venous blood samples were obtained for A1C assessment. A latent variable, “adverse psychological outcomes” comprising anxiety, depression, and diabetes distress, was derived and validated using confirmatory factor analysis. Structural equation modeling was used to test multiple psychological and behavioral pathways through which stigma was associated with A1C.
Participants had an average age of 59.44 (SD = 10.7) years, were mostly female (70.5%, n = 134), and had T2D diagnosis for a median of 14.5 years. We found significant indirect effects of T2D stigma on HbA1c through adverse psychological outcomes alone (β = 0.16; 95% CI: 0.01, 0.32, p = 0.038), as well as the combination of adverse psychological outcomes and self-management behaviors (β = 0.16; 95% CI: 0.001 to 0.32, p = 0.048). We also found that the association between T2D stigma and diabetes self-management was fully mediated by adverse psychological outcomes, and participants who conceal their diabetes tend to report greater adverse psychological outcomes.
We note that adverse psychological outcomes play a central role in how T2D stigma is associated with HbA1c. Our findings provide preliminary insight into potential aspects of diabetes that may be targeted in future stigma-reduction interventions.
Our results do provide some indication that addressing mental health issues in individuals with T2D may be an effective intervention strategy in curtailing the adverse clinical effects of T2D stigma. Additionally, our results highlight the importance of incorporating mental health care as part of routine diabetes management in Ghana and other similar African countries where mental health issues are often not prioritized by the healthcare system.

Skin inflammation arises from complex interactions among immune cells, particularly T cells and neutrophils. Mesenchymal stem cells (MSCs) exhibit potent immunomodulatory properties, but the specific roles of tonsil-derived MSCs (T-MSCs) in regulating neutrophil extracellular trap (NET) formation and cell death, as well as T cell migration in inflammatory skin conditions, remain poorly defined. In this study, the therapeutic effects and mechanisms of T-MSCs were investigated in a 2,4-dinitrochlorobenzene (DNCB)-induced skin inflammation model, with a focus on NET formation and T cell migration. T-MSCs were intravenously administered to mice with DNCB-induced skin inflammation; inflammation severity and immune cell dynamics were evaluated using histological analysis, flow cytometry, immunostaining, microarray profiling, NET assays, and T cell migration assays. T-MSC treatment reduced DNCB-induced skin inflammation, as demonstrated by decreased epidermal thickness and neutrophil infiltration. Although T-MSCs enhanced NET formation in vitro, they suppressed neutrophil accumulation in vivo. T-MSCs also modulated the distribution and activation of T cell subsets in the skin and secondary lymphoid organs. Gene expression profiling revealed that T-MSCs regulated pathways associated with inflammation and neutrophil activity, including those involved in immune cell trafficking and NET formation. Moreover, T-MSCs promoted T cell migration, although this effect was influenced by neutrophil presence, indicating complex interplay among immune cells. These findings demonstrate that T-MSCs exert anti-inflammatory effects in DNCB-induced skin inflammation by modulating NET formation and T cell migration, revealing a novel immunoregulatory mechanism and supporting their therapeutic potential for inflammatory skin diseases.To examine factors, including symptom burden profiles and self-care, associated with quality of life among individuals with heart failure and multimorbidity.
A cross-sectional design.
353 adults aged 50 years or older with heart failure and at least one additional chronic condition were recruited from a university-affiliated hospital. Three symptom burden groups were identified (low, moderate, and high) through latent profile analysis of the Edmonton Symptom Assessment Scale scores. The Heart Failure Self-care Index and EuroQoL-5D-5L measured self-care behaviours and quality of life. This study examined group differences and associations overall and stratified by symptom burden groups via multivariable linear regression.
A higher disease burden and the high symptom burden group compared to the low symptom burden group were associated with lower quality of life. Self-care maintenance was positively associated with a higher quality of life, but not in the high-burden group. Among individual symptoms, pain and depression were associated with lower quality of life. In the high-burden group, older age was positively associated with quality of life. Higher symptom burden groups included a greater proportion of women and middle-aged adults.
Symptom burden and self-care maintenance show significant associations with quality of life in multimorbidity. Symptom burden profiles identified through latent profile analysis may complement conventional approaches by targeting high-risk individuals, such as middle-aged individuals and women with high symptom burden, for follow-up and integrated multimorbidity management.
For healthcare providers, including nurses, these findings underscore the importance of holistic, symptom-based care approaches combined with routine support for self-care maintenance. Adopting a life-course approach, through early identification and management of high-risk individuals, may help promote aging in place with a better quality of life for those with heart failure and multimorbidity.

Active self-management by patients following acute coronary syndrome (ACS) can reduce recurrent events. Patient education for transitioning from hospital to home promotes effective self-management but can be limited in the acute setting due to time and resource pressures. Patients from ethnic minority and immigrant backgrounds face additional language, cultural and health literacy barriers to receiving patient education. Self-administered virtual patient education presents an innovative solution to these challenges. This study aims to evaluate a co-adapted, virtual avatar nurse-guided, discharge education application (app) for Chinese-speaking patients following ACS.
This multicentre, assessor-blinded, randomised controlled trial will recruit 98 Chinese-speaking inpatients following ACS with evaluation at 1 and 3 months postdischarge. Control participants in the control group will receive the usual ward-based patient discharge education. Intervention participants will additionally receive the education app installed on their devices before hospital discharge with unlimited access during the study period. Cultural relevance and linguistic accuracy for this Chinese version of an existing app were ensured through co-adaptation with Chinese-speaking consumers; the primary outcome will be coronary heart disease (CHD) knowledge, and secondary outcomes will include knowledge, attitudes and beliefs regarding heart attack symptoms and responses, CHD self-management behaviours, utilisation of healthcare services and quality of life. A process evaluation will be conducted alongside the trial to assess the acceptability and feasibility of the app. Between-group comparisons will be made using 95% CIs, accounting for baseline differences using linear mixed effects or mixed effects logistic regression models.
The Western Sydney Local Health District Human Research Ethics Committee has approved this study protocol (26 February 2024, amendment number 2) (2024/STE00147), with site-specific authorisations obtained from each participating hospital. The results will be disseminated through peer-reviewed journal articles and presentations at scientific conferences.

Adults with chronic kidney disease (CKD) experience a wide range of symptoms that significantly lower their health-related quality of life (HRQoL). Using mobile-based applications for symptom assessment and management has the potential to alleviate the symptom burden of CKD and improve patient outcomes.
This is a randomised feasibility trial to assess the feasibility, acceptability, usability and potential effects of a remote symptom assessment and management (SAM-CKD) 6 week programme delivered via a mobile application. Adults aged 18 years or older with CKD grade 4 or 5 (including those on dialysis) will be randomly assigned to the SAM-CKD programme or usual care. Primary outcomes assess the intervention’s feasibility, acceptability and usability. Secondary outcomes are changes in CKD symptoms and HRQoL between baseline, 3 weeks and 6 weeks later. Data analysis involves descriptive and intention-to-treat analyses. The study will be undertaken between December 2025 and March 2026. The findings will inform whether an effective trial is feasible and whether the study design and/or its methods need modification.
Ethical approval was granted by the Vin University and Griffith University Human Research Ethics Committee. Results will be disseminated at the participating hospital and CKD patient groups and shared via peer-reviewed publications and conference presentations.
This study aimed to examine the prevalence of suicide attempts among Korean adolescents before, during and after the COVID-19 pandemic and explore cross-sectional associations with demographic, psychological, behavioural and academic characteristics.
Cross-sectional analysis of three nationally representative survey waves.
The Korean Youth Risk Behavior Survey (KYRBS), an annual school-based nationwide survey in South Korea.
Adolescents with available data on key variables who participated in the 2017 (n=61 861), 2020 (n=54 809) and 2023 (n=52 802) KYRBS.
The primary outcome was a suicide attempt in the past 12 months. Secondary measures included age, sex, perceived socioeconomic status, sadness, perceived stress, alcohol use, tobacco use, lifetime drug use and subjective academic performance. These variables were measured using standardised single-item questions in the KYRBS, whereas associations were examined using multivariable logistic regression models adjusting for all covariates.
Several characteristics demonstrated consistent associations with suicide attempts. In 2017, suicide attempts were most strongly associated with sadness (OR 6.47, 95% CI 5.68 to 7.37), drug use (OR 5.60, 95% CI 4.34 to 7.24) and stress (OR 1.74, 95% CI 1.63 to 1.85). During the pandemic (2020), sadness (OR 6.35, 95% CI 5.39 to 7.48), drug use (OR 4.56, 95% CI 3.38 to 6.14) and stress (OR 2.10, 95% CI 1.94 to 2.28) preserved the strong association. In 2023, the associations persisted for sadness (OR 5.06, 95% CI 4.48 to 5.71), drug use (OR 5.31, 95% CI 4.42 to 6.39) and tobacco use (OR 2.53, 95% CI 2.15 to 2.98). Socioeconomic status showed no significant association in 2017 (OR 0.98, 95% CI 0.93 to 1.04) but demonstrated modest associations in 2020 (OR 0.91, 95% CI 0.85 to 0.97) and 2023 (OR 0.89, 95% CI 0.84 to 0.94). Subjective academic performance showed inverse associations in 2017 (OR 0.92, 95% CI 0.88 to 0.96) and 2020 (OR 0.92, 95% CI 0.87 to 0.97) but not in 2023 (OR 0.96, 95% CI 0.92 to 1.00).
Across three survey years, suicide attempts among Korean adolescents co-occurred with multiple emotional, behavioural and contextual characteristics. The magnitude of these associations varied before, during and after the pandemic, suggesting that broader social and educational conditions may shape patterns of distress linked with suicidal behaviour. Integrated approaches addressing overlapping emotional, behavioural and socioeconomic challenges may support youth suicide prevention efforts.

Vascular smooth muscle cells (VSMCs) plays an important role in maintaining vascular function by responding to various vasoactive stimuli within blood vessels. Far-infrared (FIR) rays has been shown to possess a variety of physiological effects including vasodilation, while the underlying molecular mechanism remains elusive. Here, we explored the molecular mechanism by which FIR irradiation suppresses vascular contraction using rat VSMCs and aortas. FIR irradiation enhanced the transport of intracellular Ca2+ from the cytosol to the sarcoendoplasmic reticulum (SER) via activation of sarcoendoplasmic reticulum Ca2+-ATPase (SERCA), which accompanied a decrease in intracellular ATP levels. Pretreatment with thapsigargin (TG), a specific SERCA inhibitor, or knockdown of SERCA2 gene expression reversed FIR irradiation-induced translocation of Ca2+ into the SER. Notably, FIR irradiation promoted the dissociation of SERCA2 and phospholamban (PLN), an endogenous SERCA inhibitor, without altering their total protein expression levels. The array of effects elicited by FIR irradiation was not observed under hyperthermic conditions (39°C). Moreover, FIR irradiation, but not hyperthermal condition, decreased the phosphorylation of myosin light chain (MLC) at Ser19, which was restored by pretreatment with TG or the knockdown of SERCA2 gene expression. FIR irradiation attenuated phenylephrine-induced vessel contraction in endothelium-deprived rat aortas. Consistent with the in vitro results, the reduction in MLC phosphorylation caused by FIR irradiation was reversed following pretreatment with TG in isolated aortas. Additionally, FIR irradiation increased blood flow in the carotid arteries of mice. Collectively, these results suggest that FIR irradiation activates SERCA2 by promoting its dissociation from PLN, independent of hyperthermic effects. This activation lowers cytosolic Ca²⁺ and ATP levels, reducing MLC phosphorylation and vascular smooth muscle contraction. These findings provide scientific evidence for the therapeutic potential of FIR therapy in the treatment and prevention of arterial narrowing conditions such as pathological vasospasm, and peripheral artery disease.To develop and evaluate the psychometric properties of the Forensic Nursing Competency Scale-Short Form (FNCS-SF) for hospital nurses.
Nurses who care for victims of sexual abuse, domestic violence and elder or child abuse require forensic nursing competencies. However, few valid and reliable tools exist to assess these competencies in hospital settings.
A cross-sectional study.
The study was conducted in two phases. Phase 1 involved the development and refinement of the FNCS-SF with input from 10 nurses. Phase 2 tested the tool's psychometric properties. A total of 420 nurses from two tertiary hospitals in South Korea participated. Participants were divided into two groups: Study 1 (n = 200) for exploratory factor analysis and Study 2 (n = 220) for confirmatory factor analysis.
The FNCS-SF consists of 27 items across six factors: awareness of the medicolegal problem, evidence-based practice in forensic nursing, collaborative forensic nursing with community partners, safety and security, professional career development and multidisciplinary integrated knowledge. An item analysis revealed significant correlations between each item and the total scale score. Criterion validity was supported by significant correlations between the FNCS-SF and attitudes and beliefs towards forensic nursing and the performance of the forensic nursing role. Confirmatory factor analysis supported a six-factor model with good fit indices. Cronbach's alpha indicated strong internal consistency.
The FNCS-SF is a valid and reliable tool for assessing hospital nurses' forensic nursing competencies, which can improve patient safety and treatment outcomes. Further validation in diverse clinical settings is recommended.
The FNCS-SF can be used to improve forensic nursing competency through professional development.
None.
The FNCS-SF provides a standardised framework to evaluate nurses' forensic competency, guiding education and practice to enhance clinical preparedness and deliver victim-centred care.

ObjectivesThis study aimed to determine the preferred timing and measurement sites for electroneuronography (ENoG) to predict early recovery from acute peripheral facial paralysis.
MethodsWe retrospectively evaluated 42 patients with acute peripheral facial paralysis who received standard treatment with oral corticosteroids. The severity of facial paralysis was assessed at the initial visit and after 1 month using the House–Brackmann grading system. Patients were classified into recovery and non-recovery groups according to changes in the grade. ENoG was performed at the initial visit and after 2 weeks. ENoG amplitudes of four facial muscles (frontalis, nasalis, orbicularis oculi, and orbicularis oris) at the initial visit and after 2 weeks, as well as age, sex, affected side, and diagnosis, were compared between the two groups.
ResultsNo differences were observed in degeneration ratios across all subsites in the initial ENoG, which can be explained by the fact that Wallerian degeneration is not yet complete at this early stage. However, the second ENoG, performed after degeneration had progressed, showed significant differences across all subsites. Binary logistic regression analysis revealed that the degeneration ratio of the orbicularis oris muscle was the best predictor of early recovery (odds ratio, 0.961; p = 0.014). Receiver operating characteristic curve analysis also revealed that the degeneration ratios of all subsites measured in the second ENoG were useful in predicting early recovery, with the highest possibility at the orbicularis oris muscle (area under the curve = 0.789). When the degeneration ratio exceeded 60% in all subsites in the second ENoG, a favorable prognosis was not expected.
ConclusionThis study provides the preferred testing time and measurement sites for ENoG to predict early recovery from facial paralysis. Given the personal and social impact of facial paralysis, predicting early recovery is crucial for reassuring patients, providing better treatment, and encouraging early reintegration into society.

ObjectiveRegarding revision of vascular access (VA), endovascular methods are commonly employed owing to their procedural simplicity, yet their durability remains uncertain. This study aimed to compare clinical outcomes of swing segment (SwS) revision of radiocephalic arteriovenous fistula (RC-AVF) between endovascular and surgical approaches.
Materials and methodsA retrospective cohort study comparing two groups was conducted at one tertiary hospital in South Korea. A total of 131 patients underwent endovascular or surgical revision of SwS in RC-AVF for the first time after AVF creation between 2016 and 2023. Endovascular and surgical revisions were performed in 114 and 17 patients, respectively (interposition, n = 10; patch angioplasty, n = 5; transposition, n = 1; proximalization, n = 1). Kaplan-Meier survival analysis was used to assess post-intervention primary patency (PP) and post-intervention secondary patency (SP). Multivariable Cox regression analysis was performed to adjust for potential confounders, and a subgroup analysis was conducted based on whether the SwS was in stenosis or occlusion.
ResultsThe median minimal diameter of SwS was 1.3 mm in the endovascular group and 1.4 mm in the surgical group, and the median lesion length was 2.5 cm and 4.0 cm, respectively. Twelve-month PP was 63.5% vs 73.7% (endo vs surgical, P = 0.79). While PP did not differ in the stenosis subgroup, the occlusion subgroup showed significantly higher PP after surgical revision (P = 0.002), with surgery associated with a markedly lower risk of loss of PP events (HR 0.073).
ConclusionSurgical revision may be preferentially considered for long-segment occlusive lesions, given its superior early PP and the longer lesions typically associated with occlusions, whereas percutaneous transluminal angioplasty (PTA) remains appropriate for focal or stenotic lesions within the SwS. Consistent follow-up is essential to enable timely interventions, thereby maximizing the functionality of RC-AVF.

PurposeOptimal perioperative antibiotic prophylaxis in kidney transplantation remains undefined despite routine antibiotic administration to prevent infections. In this retrospective observational cohort study with historical comparison, we compared the clinical efficacy of 6 days of ampicillin/sulbactam vs. a single dose of cefazolin.
Materials and methodsWe retrospectively analyzed 2322 kidney transplantation recipients at a single center, with the evaluation period spanning from 2015 through 2021. Patients were divided into 2 groups based on the perioperative antibiotic regimen received: 971 patients received ampicillin/sulbactam, and 1351 received cefazolin. This study focused on evaluating the impact of these regimens on postoperative infection incidence and the 6-month acute rejection (AR) rates.
ResultsThe cefazolin group exhibited a tendency toward higher urinary tract infection rates within 1 month after transplantation (3.4% vs. 2.2%, p= = 0.078). There were no significant differences in surgical site infections between the groups. The 6-month AR rates were significantly lower in the cefazolin group than in the ampicillin/sulbactam group (5.1% vs. 7.9%, p= = 0.009). Cefazolin was also confirmed to be significantly associated with reduced 6-month AR rates in the multivariable logistic regression analysis (odds ratio 0.63, 95% confidence interval [0.45-0.89], p= = 0.009).
ConclusionIn this study, we observed that a single dose of cefazolin as perioperative antibiotic prophylaxis may lead to higher rates of postoperative urinary tract infections, but it could potentially lower the incidence of acute rejection within six months.
This study examined factors associated with the use of Indonesia’s National Health Insurance (NHI) among its beneficiaries in Maluku province.
Cross-sectional study.
The individual-level data were derived from the 2021 Social Health Insurance Sample Data. National health reports of Indonesia were used to provide the district-level variables. We performed multivariable logistic regression analyses to identify factors associated with NHI use among its beneficiaries in Maluku province.
Data were collected from 31 517 NHI beneficiaries registered in Maluku.
The primary outcome was the use of NHI insurance when accessing healthcare services (yes/no).
Only 14.79% of NHI beneficiaries in Maluku had ever used their insurance for healthcare services. Individual factors associated with higher NHI use included being under 60 years, females (adjusted OR (aOR)=1.29, p
Strengthening primary healthcare accessibility, improving the distribution of healthcare workers and addressing socioeconomic and geographical disparities are essential to ensure that the NHI scheme achieves equitable use across all regions in Maluku and other areas with similar settings.
This study aimed to investigate whether psychological distress mediates the relationship between secondary traumatic stress (STS) and post-traumatic stress symptoms (PTSS) among clinical nurses, and whether perceived emotional support moderates this mediating effect.
A cross-sectional study.
A total of 205 clinical nurses who had direct patient contact and trauma-related experience were included. Data were collected using validated instruments: the Secondary Traumatic Stress Scale (STSS), Depression Anxiety Stress Scale-12 (DASS-12), Impact of Event Scale-Revised (IES-R), and the Multidimensional Scale of Perceived Social Support (MSPSS). All scales demonstrated high internal consistency (Cronbach's α = 0.88–0.97).
Psychological distress significantly mediated the relationship between STS and PTSS. Perceived emotional support moderated the path from STS to psychological distress, such that higher emotional support amplified the association. However, emotional support did not significantly moderate the relationship between psychological distress and PTSS.
Psychological distress plays a central role in translating STS into PTSS among clinical nurses. Although emotional support may buffer early psychological distress, it does not attenuate PTSS development once distress is established.
Early detection and management of psychological distress can prevent STS from progressing to PTSS. Nurses frequently exposed to trauma require timely psychological support. We recommend implementing routine screening and early interventions focused on distress, along with peer-support programmes and supervisory encouragement to enhance resilience. Trauma-informed care training and organisational awareness should also be strengthened to foster a supportive environment.
This study shows that managing early emotional symptoms is critical in preventing PTSS among nurses exposed to secondary trauma. Findings can inform global policies, peer-support initiatives, and early screening systems to enhance resilience and safeguard patient care.
The study adhered to the STROBE checklist for cross-sectional studies.

BackgroundRadiotherapy for locally advanced esophageal cancer can induce lymphopenia, potentially worsening outcomes. This study examines the association between clinical outcomes and the effective dose to the immune cells (EDIC), a measure of lymphocyte radiation exposure.
MethodsWe retrospectively analyzed 107 patients with locally advanced esophageal squamous cell carcinoma treated with definitive concurrent chemoradiotherapy (CCRT). The EDIC was calculated based on the mean lung dose, mean heart dose, and integral total body dose using established models. Patients were stratified into high (n = 42) and low (n = 65) effective dose to the immune cells (EDIC) groups using a cut-off value of 4.28 Gy. Survival outcomes, including overall survival (OS), progression-free survival (PFS), locoregional failure-free survival (LRFS), and distant metastasis-free survival (DMFS), were assessed.
ResultsThe 5-year OS and PFS rates were significantly lower in the high EDIC group than in the low EDIC group (51.9% vs. 66.6%, p = 0.043; 20.8% vs. 31.8%, p = 0.002, respectively). Multivariate analysis identified high EDIC as an independent predictor of poorer OS (hazard ratio (HR): 2.06, 95% confidence interval (CI): 1.1–3.86, p = 0.024) and PFS (HR: 1.7, 95% CI: 1.04–2.78, p = 0.034). Similarly, the 5-year LRFS and DMFS rates were significantly lower in the high EDIC group than in the low EDIC group (24.1% vs. 34.9%, p = 0.003; 29.0% vs. 44.0%, p = 0.018, respectively).
ConclusionA higher EDIC is an independent predictor of poor survival in patients with esophageal squamous cell carcinoma undergoing CCRT. Reducing radiation exposure to the immune system through optimized radiation planning and lymphocyte-sparing techniques may improve patient outcomes.
