Objective: To explore the application effectiveness of healthcare failure mode and effect analysis (HFMEA) in optimizing intelligent blood logistics transport pathways for safety assurance. Methods: Data from 1 851 cases of intelligent blood logistics transport were collected between September 2023 and March 2025. Based on the implementation phases of HFMEA measures, the cases were divided into a control group (n=120), observation group 1 (n=219), and observation group 2 (n=1 512). Through systematic analysis of the transport processes, hazard scoring and decision tree analysis were conducted for each process, and phased optimization measures were implemented for high-risk failure modes. Results: The transport duration of intelligent blood logistics was 35.5 (20.8, 71.1) min in the control group, 25.1 (10.9, 40.7) min in observation group 1, and 9.9 (4.2, 44.5) min in observation group 2. Observation group 2 exhibited significantly shorter transport time compared to both observation group 1 and the control group, with statistically significant differences between groups (P<0.000 1). Conclusion: The implementation of HFMEA-driven measures significantly reduced intelligent blood logistics transport duration, thereby fostering the evolution of smart hospital ecosystems while enhancing healthcare service quality and operational efficiency.

摘要 目的 肝豆状核变性（又称Wilson病，WD）是由ATP7B基因突变引起的铜代谢紊乱疾病，常累及肝脏和中枢神经系统，严重者可致死。目前关于WD患者死亡原因及危险因素的系统研究较少。本研究旨在探讨WD患者的常见死亡原因及其危险因素。方法 回顾性分析2011年1月—2022年1月间安徽中医药大学神经病学研究所附属医院87例死亡WD患者和113例存活WD患者的临床资料，分析死亡原因，并通过Cox回归分析死亡危险因素。结果 死亡组年龄中位数为32.00（27.00，41.00）岁、病程中位数为144.00（72.00，228.00）个月，存活组年龄中位数为31.00（25.00，37.00）岁、病程中位数为132.00（72.00，214.00）个月。主要死亡原因包括肝衰竭（33例）、感染（23例）、猝死（8例）、消化道出血（8例）及肝癌（4例）等。死亡组与存活组在性别、起病形式、低铜饮食、肝脏B超分型、脾脏切除、临床分型、治疗方案及多项实验室指标（如白细胞计数、TB、Alb等）上差异有统计学意义（P<0.05）。多因素Cox回归显示，基线尿铜每增加100 μg/24 h（HR=1.22， 95%CI 1.11~1.34）与肝硬化（HR=2.55，95%CI 1.02~6.36）使死亡风险增加。结论 WD患者的主要死亡原因为肝衰竭，高水平基线尿铜和肝硬化显著增加死亡风险。尿铜水平达400 μg/24 h（参考值<100 μg/24 h）的患者死亡风险较基线增加3.8倍（HR=3.8，P<0.001）。研究结果为WD患者的预后评估和临床干预提供了重要依据。 Abstract Objective Hepatolenticular degeneration（also know as Wilson disease ，WD） is a copper metabolic disorder caused by ATP7B gene mutation， often involving the liver and the central nervous system and leading to death in severe cases. At present， there is a lack of systematic studies on the cause of death and related risk factors in WD patients. Therefore， this study aims to investigate the common causes of death and related risk factors in WD patients. Methods A retrospective analysis was performed for the clinical data of 87 WD patients who died and 113 WD patients who survived in our hospital from January 2011 to January 2022. The common causes of death in WD patients were analyzed， and the Cox proportional-hazards regression model analysis was used to investigate the risk factors for death. Results The death group had a median age of 32.00 （27.00，41.00） years and a median course of disease of 144.00 （72.00，228.00） months， and the survival group had a median age of 31.00 （25.00，37.00） years and a median course of disease of 132.00 （72.00，214.00） months. The main causes of death included liver failure （33 patients）， infection （23 patients）， sudden death （8 patients）， gastrointestinal bleeding （8 patients）， and liver cancer （4 patients）. There were significant differences between the death group and the survival group in sex， pattern of disease onset， low copper diet， liver ultrasound classification， splenectomy， clinical classification， treatment regimens， and various laboratory markers （such as white blood cell count， total bilirubin， and albumin）（P<0.05）. The multivariate Cox regression analysis showed that the risk of death was doubled for every 100 μg/24 h increase in urinary copper at baseline （HR=1.22，95%CI 1.11-1.34） and the presence of liver cirrhosis （HR=2.55，95%CI 1.02-6.36）. Conclusion Liver failure is the main cause of death in WD patients， and a high level of urinary copper at baseline and the presence of liver cirrhosis significantly increase the risk of death. The risk of death in patients with a urinary copper level of 400 μg/24 h （reference value<100 μg/24 h） was increased by 3.8 times compared with the value at baseline （HR=3.8，P<0.001）.The results of this study provide an important basis for the prognosis evaluation and clinical intervention of WD patients.

Background: s/Aims: This study evaluated the feasibility and outcomes of surgical treatment for metachronous periampullary carcinoma following curative resection of primary extrahepatic bile duct cancer. Methods: A retrospective review was conducted of seven patients who underwent pancreaticoduodenectomy (PD) for metachronous periampullary cancer after prior curative surgery for extrahepatic bile duct cancer. Results: The mean age at the second surgery was 66.7 years (range, 43–81 years). Initial malignancies included three hilar cholangiocarcinomas, one middle bile duct cancer, and three gallbladder cancers. Subsequent primary tumors consisted of three distal bile duct cancers, three pancreatic head cancers, and one duodenal cancer. The mean interval between the first and second cancers was 47 months (range, 13–121 months). No perioperative deaths occurred. Postoperative complications developed in three patients (42.9%):chyle leakage (Clavien–Dindo grade II) in two (28.6%) and a grade C postoperative pancreatic fistula requiring reoperation (grade IIIb) in one (14.3%). Both chyle leaks were managed conservatively. During follow-up, four patients died of recurrence at 5, 12, 19, and 24 months postoperatively. One patient underwent video-assisted thoracoscopic surgery for pulmonary metastasis 2 months after PD and remains alive 22 months later without recurrence. Two patients are disease-free at 38 and 92 months of follow-up. Conclusions PD for second primary periampullary cancer after resection of extrahepatic bile duct cancer appears feasible and potentially effective. Although no perioperative mortality occurred, major complications were observed. Larger studies are needed to confirm these preliminary findings.

Vaccines are highly effective, but rare or delayed adverse events following immunization (AEFIs) require post-licensure surveillance beyond clinical trials. Korea lacks a comprehensive, active, database-based framework, yet key assets exist: nationwide claims databases (National Health Insurance Service/Health Insurance Review and Assessment Service), the national immunization registry (Korea Disease Control and Prevention Agency’s Immunization Registry Information System) for National Immunization Program (NIP) and non-NIP vaccines, and increasingly standardized hospital electronic health records.We propose a federated, code to data architecture with data linkages between these data.Implementation should adopt a common data model (CDM), standardized case definitions, latency accounting, and transparent public reporting under strong privacy governance. Major challenges include multi step administrative approvals for data linkage, incomplete capture of adult non-NIP vaccinations, heterogeneous hospital data structures, and strict data protection constraints. Strategic priorities are to streamline statutory and administrative processes for public health use, mandate or enable claims-based capture of adult vaccinations, enhance CDM based interoperability, and develop secure hubs for aggregated outputs. With these measures, Korea will be well positioned to establish a scalable active surveillance system capable of detecting rare AEFIs, supporting transparent and evidence-based communication, and ensuring equitable injury compensation grounded in domestic data.

Objective: Research specifically targeting suicidal ideation (SI) in middle-aged populations remains limited. This study aimed to predict future and concurrent SI in middle-aged Korean adults by applying four machine learning (ML) models to a nationally representative longitudinal dataset. Methods: We analyzed data from 8,992 individuals aged 40–64 years who participated in the Korea Welfare Panel Study from the 7th (2011) to the 18th (2022) waves. Four ML algorithms were employed to develop the predictive models. The SHapley Additive exPlanations method was applied to enhance explainability. Results: Approximately half of the participants’ mean age was 49.3±8.2 years (range, 40–64 years) and 52.2% were male. The average annual SI rate between 2011 and 2022 was 2.8%±1.2%. Predictive performance for future SI was satisfactory, with area under the receiver operating characteristic curve (AUC) values of up to 0.806 (logistic regression, LR). Predictions for concurrent SI demonstrated AUC values of up to 0.907 (LR). Key predictors of future SI included subjective health status, satisfaction with family and spousal relationships, housing environment, and educational attainment. Concurrent SI was strongly associated with immediate stressors such as family violence and income dissatisfaction. Conclusion The ML models demonstrated good-to-excellent predictive performance for SI. These findings emphasize the importance of health, family, and socioeconomic factors, alongside mental health indicators in the prevention of SI among middle-aged adults. Building on these findings, tailored intervention strategies that comprehensively address multidimensional risk factors are essential for effective SI prevention.

The surgical management of empyema (excluding those caused by mycobacterium tuberculosis and non-tuberculous mycobacteria) is rapidly evolving towards minimally invasive, precise, and stepwise approaches. The traditional three-stage classification (exudative, fibrinopurulent, and organizing) has limitations in guiding dynamic clinical decision-making. For the first time, this consensus explicitly identifies two critical junctures in the pathological progression of empyema: "early transformation" (stage Ⅰ to Ⅱ) and "late transformation" (stage Ⅱ to Ⅲ), and thereby constructs a corresponding "identification-early warning-intervention" stepwise therapeutic framework. The consensus emphasizes that proactive debridement via video-assisted thoracoscopic surgery should be performed during the early transformation phase to halt disease progression. Conversely, during the late transformation phase, therapeutic goals should be rationally adjusted to prioritize adequate drainage, avoiding futile pleural decortication. Moreover, the consensus underscores the pivotal role of precise perioperative etiological diagnosis (e.g. metagenomic nest-generation sequencing) and standardized anti-infective therapy. Integrating practical experiences from multiple thoracic surgery centers in China and relevant evidence-based literature, this consensus formulates recommendations on the precise definitions of staging, surgical indications for each phase, key technical points, perioperative management, and training systems. It aims to promote the standardized and individualized surgical management of empyema, ultimately optimizing patient prognosis.

This study systematically examined the effects of atomization as a transdermal permeation enhancer on the transdermal delivery of active ingredients with different physicochemical properties and investigated the underlying mechanisms. Porcine ear skin served as an in vitro model, and skin permeation experiments were conducted using Franz diffusion cells. Receptor fluids were collected at specific time points, and samples of the stratum corneum and viable epidermis–dermis were separated and prepared. Quantitative and visualization methods, including high-performance liquid chromatography, fluorescence derivatization, and confocal laser scanning microscopy, were used to compare skin retention and transdermal permeation of adenosine (AD), tranexamic acid (TXA), calcein (CAL), and tocopheryl acetate (TA) under atomized and non-atomized conditions. Additionally, transepidermal water loss (TEWL) measurements and attenuated total reflectance–Fourier transform infrared spectroscopy (ATR-FTIR) were employed to analyze the mechanism behind the penetration enhancement caused by atomization. The findings showed that atomization increased skin retention within the stratum corneum and viable epidermis–dermis, as well as the transdermal permeation of all four active ingredients to varying degrees. The most significant enhancement was observed for TXA, which has a relatively low molecular weight and moderate lipophilicity, while the enhancement effects for highly hydrophilic AD and highly lipophilic TA were comparatively limited; however, atomization significantly increased the skin retention of TA. TEWL results indicated that skin permeability increased within 4 hours after atomization and largely recovered within 8 hours. ATR-FTIR analysis suggested that atomization may facilitate transdermal delivery by disrupting the lipid order and keratin conformation in the stratum corneum.This study provides theoretical support and experimental references for the advancement of atomization transdermal delivery technology, as well as the design and development of related atomization products.

Introduction: Current education on diabetes self-management is time-consuming as it is conducted face-to-face. This study aimed to evaluate the effectiveness of diabetes education via mobile application on hemoglobin A1c (HbA1c). Methodology: This was a double-blinded randomized controlled study conducted in the Department of Endocrinology, Hospital Pulau Pinang and Hospital Raja Permaisuri Bainun. Participants were stratified randomized according to HbA1c to intervention group (using T-Manis) and control group. The primary objective was to assess the difference in HbA1c between the groups. Secondary objectives were to assess the difference in body weight, hospitalization related to diabetes, diabetes knowledge between groups and usability and satisfaction of T-Manis. Laboratory investigations and questionnaires were conducted at baseline, 4 months and 8 months. Results: A total of 112 participants were randomized into two groups each with 56 participants. Mean age was 51 years with similar diabetes duration of 16 years in both groups. Participants comprised of 61.6% females with ethnic distribution of 49.1% Malay, 30.4% Chinese, 19.6% Indian and 0.9% Siamese. Baseline HbA1c levels were comparable between intervention and control groups (10.04% versus 9.91%; mean difference 0.13%; 95% CI −0.56 to 0.81; p = 0.718). At 4 months, HbA1c of the intervention group demonstrated a significant reduction compared to the control group (8.93% versus 9.80%; mean difference −0.86; 95% CI −1.59 to −0.14; p = 0.02). Sustained reduction of HbA1c in the intervention group was observed at 8 months (mean difference −1.01; 95% CI −1.85 to −0.16; p = 0.02). Baseline body weight was 77 kg, with no betweengroup differences in body weight, hospitalization related to diabetes and diabetes knowledge scores, although diabetes knowledge scores improved at 4 months in the intervention group. 89.3% of participants reported satisfaction with T-Manis Conclusion The T-Manis mobile application aided in significantly improving glycemic control with high user satisfaction, supporting its feasibility as an adjunct to standard diabetes care.

BACKGROUND:How to repair bone defect has been a clinical problem for a long time.The effective ingredients of traditional Chinese medicine have good biological activity and therapeutic effect,and the combination of effective ingredients of traditional Chinese medicine and tissue engineering materials has a broad prospect in the field of bone repair.The combination of different effective ingredients of traditional Chinese medicine and scaffolds has similarities in their functional relationships. OBJECTIVE:To collect the cases of the combinations of effective ingredients of traditional Chinese medicine and scaffolds,then analogize tissue engineering scaffolds and effective ingredients of traditional Chinese medicine into two types of traditional Chinese medicine that generate compatibility relationships based on the inspiration of the compatibility of seven emotions and summarize the relationship between the two based on their functional relationships. METHODS:Relevant articles from January 1998 to January 2024 were searched in PubMed and China National Knowledge Infrastructure(CNKI),using English search terms"traditional Chinese medicine,Chinese medicine,traditional Chinese medicine monomers,bone defect,bone repair,bone tissue engineering,tissue engineering,scaffold"and Chinese search terms"traditional Chinese medicine,effective ingredients of traditional Chinese medicine,traditional Chinese medicine monomers,bone tissue engineering,bone tissue engineering scaffold,scaffold,tissue engineering,bone defect,bone repair."A total of 88 articles were included for review and analysis. RESULTS AND CONCLUSION:(1)Both tissue engineering scaffold materials and active ingredients of traditional Chinese medicine have been widely used in the field of bone repair.Although they have obvious advantages in osteogenesis,there are still many shortcomings.Many studies are dedicated to preparing composite materials from the two,hoping to exert a detoxification and synergism through the interaction between the two.(2)Some drugs and materials can promote each other in osteogenesis,antibacterial,and promoting angiogenesis,enhancing their original effects.Inspired by the traditional concept of prescription compatibility,this article summarized it as a"Mutual promotion"relationship and provided examples to support it.(3)Some drugs can enhance the strength of materials,while some materials can achieve sustained release and controlled release effects,increase drug loading and stability,or achieve targeted delivery of drugs loaded on them.The article summarized this unilateral enhancement effect as a"Mutual assistance"relationship.(4)The combination of some traditional Chinese medicine and materials can reduce the toxic side effects of the other party.The article summarizes this detoxification relationship as"Mutual restraint and detoxification."(5)The article provided a new perspective on traditional Chinese medicine composite scaffolds,inspired by the seven emotions compatibility relationship and based on the classification of action relationships.It introduced traditional Chinese medicine concepts into the field of tissue engineering,providing new research ideas for subsequent researchers of composite scaffolds,and providing certain convenience in material selection and matching.

South Korea’s current vaccination policies leave a surveillance gap for non-National Immunization Program (NIP) vaccines. In this study, we proposed a sentinel surveillance approach for monitoring the safety of non-NIP vaccines. Vaccination data were collected retrospectively among patients hospitalized with pre-defined adverse events of special interest (AESI) by reviewing electronic medical records in five university hospitals. This approach incorporates expert assessment to determine the causal relationship. We confirmed that 16 patients had received non-NIP vaccines among 860 patients diagnosed with AESI.We concluded one case of preeclampsia was possibly related to tetanus-diphtheria-pertussis vaccination. We propose a multi-hospital-based, retrospective assessment system for predefined AESIs as an alternative to active vaccine safety monitoring method. These efforts are expected to enhance both the accuracy and timeliness of safety monitoring in South Korea.
