Background: The digitisation of healthcare has generated vast amounts of data in various formats, including free-text notes, tabular records and medical images. This data is critical for research and innovation, but often contains sensitive information that must be de-identified to ensure patient privacy and regulatory compliance. Natural Language Processing (NLP) enables automated de-identification of sensitive information to safely share medical datasets.
Objective: This study aims to systematically review the literature on NLP-based de-identification techniques applied to free-text medical reports, tabular data, and burned-in text within medical images over the past decade. It seeks to identify state-of-the-art methods, analyse how de-identification tasks are assessed, and find existing gaps for future research.
Methods: We systematically searched five important databases (PubMed, Web of Science, DBLP, ACM and IEEE) for articles published from January 2015 to December 2024 (10 years) about de-identification of medical data in free text, tabular data and burned-in pixels in images. We filtered the articles based on their titles and abstracts against inclusion and exclusion criteria, followed by a quality filter.
Results: From a set of 734 papers, 83 articles were deemed relevant. Most studies de-identify free text, with a few working with tabular data and a much scarcer number dealing with text embedded in the pixels of the images.
Conclusions: De-identification techniques have evolved, with increased use of Language Models and a decline in recurrence-based neural networks. Off-the-shelf tools often require customisation for optimal performance. Most studies de-identify English content, supported by the prevalence of English datasets. Key challenges include the phenomenon of code-mixing (i.e., more than one language used in the same sentence) and the scarcity of available datasets for reproducibility.
背景:医疗保健的数字化产生了各种格式的大量数据,包括自由文本注释、表格记录和医学图像。这些数据对研究和创新至关重要,但通常包含必须去识别的敏感信息,以确保患者隐私和法规遵从性。自然语言处理(NLP)实现了敏感信息的自动去识别,以安全地共享医疗数据集。目的:本研究旨在系统回顾过去十年来基于nlp的去识别技术在医学图像中应用于自由文本医学报告、表格数据和烧入文本的文献。它试图确定最先进的方法,分析如何评估去识别任务,并为未来的研究找到现有的差距。方法:系统检索5个重要数据库(PubMed、Web of Science、DBLP、ACM和IEEE),检索2015年1月至2024年12月(10年)发表的关于自由文本、表格数据和图像中烧毁像素的医疗数据去识别的文章。我们根据标题和摘要对文章进行筛选,然后进行质量筛选。结果:在734篇论文中,83篇文章被认为是相关的。大多数研究都去识别自由文本,只有少数研究处理表格数据,而处理嵌入图像像素中的文本的研究则少得多。结论:随着语言模型的使用增加和基于递归的神经网络的减少,去识别技术已经发展。现成的工具通常需要定制以获得最佳性能。由于英语数据集的普及,大多数研究都去识别英语内容。主要的挑战包括代码混合现象(即,在同一个句子中使用多种语言)和缺乏可用于再现性的可用数据集。

Introduction
The Patient Summary (PS), a standardized subset of the electronic health record is designed to provide essential patient information for use in emergencies, unplanned care, and cross-border healthcare. While its technical development has progressed across Europe, little is known about real-world PS adoption and physician perceptions at the national level. This study explores the awareness, usage, and perceived barriers to the PS adoption among Czech physicians.
Methods
A cross-sectional online survey was distributed to all registered physicians in the Czech Republic between February and March 2025. The questionnaire assessed demographic characteristics, PS usage patterns, perceived benefits and barriers, and alignment with clinical practice. Descriptive statistics were calculated, and non-parametric tests (Wilcoxon rank-sum, Kruskal–Wallis) were used to examine differences by years of experience and medical specialty.
Results
A total of 1,739 responses were received (response rate: 4.14 %). Most respondents (66.4 %) reported not using the PS at all, and 72.1 % were unaware that their electronic medical record could be connected to the National Contact Point for eHealth. Only 1.7 % reported a current connection. There was no significant difference in PS use by years of clinical experience (P = 0.391), but a significant difference was observed across specialties (P < 0.001), with the highest usage reported in intensive care medicine and internal medicine.
Discussion and conclusion
Despite recognized benefits, PS usage remains low in the Czech Republic, largely due to limited awareness and system integration. Targeted policy measures, improved communication, and enhanced digital training are needed to support effective adoption.

Background and purpose
The rapid integration of artificial intelligence (AI) into stroke care has outpaced many clinicians’ ability to critically evaluate and safely implement these tools. We conducted a systematized literature review and developed a practical framework to guide neurologists in the responsible integration of AI into stroke practice.
Methods
We performed a systematized review of PubMed, EMBASE, and gray literature (January 2018-June 2025) following adapted PRISMA guidelines. Search strategies combined AI-related terms with stroke care concepts. We assessed risk of bias using QUADAS-2, RoB 2, and ROBINS-I tools. Expert consultation with stroke neurologists and AI developers informed framework development.
Results
From 8,635 identified records, 152 studies met inclusion criteria (47 in quantitative synthesis). AI applications spanned large vessel occlusion detection (30 %), ASPECTS scoring (21 %), outcome prediction (18 %), hemorrhage detection (15 %), and treatment selection (16 %). Only 23% of studies showed low risk of bias, with main concerns including selection bias (29 %), confounding (38 %), and limited external validation (8 % prospective validation). The Clinical-AI Correlation Framework emphasizes three pillars: (1) problem identification and tool selection, (2) clinical correlation using Bayesian reasoning and topographic pattern recognition, and (3) continuous feedback and quality improvement.
Conclusions
Safe AI integration in stroke care requires structured clinical correlation, robust governance frameworks, and continuous monitoring. Our framework provides practical guidance for maintaining clinical judgment while leveraging AI capabilities, emphasizing human oversight for high-risk decisions and systematic documentation of AI-clinician interactions.

Cancer prognosis of complications like metastasis, recurrence, and side effects of treatments is important to enhance patient prognosis. There is great potential in the use of ML on lifetime data for improving prediction accuracy in oncology; however, there is no systematic review of the subject. This SRMA is intended to assess the accuracy of ML models based on longitudinal studies for the estimation of cancer-related complications. The articles were identified from PubMed, Google Scholar, and IEEE Xplore databases for the years 2020 to 2024. Seven of the studies reviewed in the paper analyzed ML models that employed longitudinal data for cancer complication prognosis. The risk of bias of included studies was assessed using the Cochrane Risk of Bias tool, and for diagnostic accuracy, the QUADES 2 tool was used. Information on ML techniques, prediction accuracy, and results was obtained. The pooled area under the curve (AUC) for immune-related adverse events prediction was 0.78 (95% CI: 0.73–0.83). For cancer recurrence and mortality prediction, pooled AUCs ranged from 0.70 to 0.75. Machine learning models integrating clinical, genomic, and imaging data demonstrated superior predictive accuracy across various cancer types. Models predicting quality of life deterioration during treatment showed an AUC of 0.82. ML models applying longitudinal data effectively predict cancer complications with improved accuracy when integrating multimodal data. These models offer promising tools for clinical decision-making in oncology.

Background
Traumatic brain injury (TBI) is a major risk factor for neurological disorders, including post-traumatic epilepsy (PTE), a debilitating condition associated with significant long-term consequences. The prognosis of PTE occurrence remains challenging due to the complex pathophysiology of PTE and the impracticality of traditional blood biomarker- or imaging-based screening for large populations. This study proposes a graph-based deep learning approach that leverages electronic health records (EHR) to enhance the predictive assessment of PTE risk.
Methods
We utilized Oracle Real-World Data (ORWD) to construct a Heterogeneous Graph Attention Network (HeteroGAT) that contains patient and diagnosis nodes, with temporal information represented using patients-to-diagnosis edges, and comorbidity connectivity embedded using diagnosis-to-diagnosis edges. The HeteroGAT was trained on a cohort of 1,598,998 TBI-only patients and 102,687 individuals who developed epilepsy after TBI. Model performance was evaluated using sensitivity, specificity, macro F1-score, and area under the receiver operating characteristic curve (AUC-ROC), benchmarked against traditional machine learning models. Attention scores of nodes were used to evaluate node importance. The capabilities of the HeteroGATs trained to differentiate early vs late PTE patients following TBI were also assessed.
Results
HeteroGAT significantly outperformed conventional models in PTE prediction by effectively integrating demographic data and comorbidity profiles spanning from 20 to 500 distinct conditions. The model’s multi-head attention mechanisms, in combination with learned comorbidity connectivity, enhanced its ability to capture complex dependencies within EHR data. HeteroGAT achieved an AUC-ROC of 0.80, outperforming the best-performing traditional model, random forest (AUC-ROC = 0.77). HeteroGAT also demonstrated capabilities in differentiating early and late PTEs. Ranking of nodes based on attention scores also identified predictors of PTE that are clinically relevant.
Conclusion
By modeling sparse EHR data through patient encounter embeddings, HeteroGAT effectively captures temporal and relational patterns in comorbidities critical for PTE prediction. Our findings highlight the potential of graph-based deep learning models, synergized with large-scale EHR data, in advancing personalized risk assessment, ultimately addressing the urgent need for more precise and proactive management of PTE in TBI patients.

Background
Sepsis represents a life-threatening complication in severe orthopedic trauma, significantly increasing short-term mortality risk. Despite the clinical urgency for early prognosis assessment, current predictive tools remain inadequate. To address this gap, this study used a machine learning (ML)-based framework for mortality risk stratification in this high-risk population.
Methods
This retrospective cohort study established ML models to predict 30-day all-cause mortality in critically ill patients with orthopedic trauma and sepsis. Data from 2,060 eligible patients were extracted from the intensive care unit (ICU) of Beth Israel Deaconess Medical Center (2008–2019) in the United State and randomly split into training (80 %) and internal validation (20 %) sets. After handling missing data and addressing class imbalance, seven ML algorithms (including CatBoost [Categorical Boosting], RF [Random Forest], and SVM [Support Vector Machine]) were trained and optimized using 10-fold cross-validation. Model performance was assessed based on discrimination (AUC [Area Under the Curve], accuracy, F1-score), calibration (Brier score, calibration slope), and clinical utility. The top-performing models were further validated on an independent external Chinese cohort (n = 273, 2020–2024).
Results
The study cohort had a mean age of 62.8 years and a 30-day mortality rate of 19.9 % (410/2060). Non-survivors were significantly older, had a higher comorbidity burden, and more severe physiological derangements. The LASSO analysis identified 16 prognostic variables, with age, hematologic parameters (RDW, WBC), SOFA scores, hemodynamic measures (SBP), and antihypertensive therapy emerging as significant predictors. Among all models, the CatBoost algorithm demonstrated superior performance in the internal validation set, achieving the highest AUC (0.955), accuracy (0.884), and F1-score (0.878), along with excellent calibration (Brier score: 0.081). A soft voting ensemble model, integrating the top three algorithms (CatBoost, RF, SVM), was subsequently constructed. In external validation, this ensemble model generalized robustly, maintaining strong discrimination (AUC: 0.842, Accuracy: 0.737) and calibration (Brier score: 0.173), outperforming the standalone CatBoost model. SHapley Additive exPlanations analysis provided interpretable, individualized risk assessments.
Conclusions
This study trains, optimizes, and evaluates a high-performing ML-based prediction model for 30-day mortality in patients with critical orthopedic trauma and sepsis. The CatBoost model and the soft voting ensemble, particularly the latter, demonstrates strong generalizability and clinical utility, offering a potential tool for early risk stratification and personalized management in this vulnerable population.
脓毒症是严重骨科创伤中一种危及生命的并发症,显著增加短期死亡风险。尽管临床迫切需要早期预后评估,但目前的预测工具仍然不足。为了解决这一差距,本研究在这一高危人群中使用了基于机器学习(ML)的死亡率风险分层框架。方法回顾性队列研究建立ML模型,预测骨科创伤合并脓毒症危重患者30天全因死亡率。从美国贝斯以色列女执事医疗中心(Beth Israel Deaconess Medical Center)重症监护室(ICU)提取2060例符合条件的患者数据(2008-2019),随机分为训练组(80%)和内部验证组(20%)。在处理缺失数据和解决类不平衡问题后,使用10倍交叉验证对七种ML算法(包括CatBoost [Categorical Boosting], RF [Random Forest]和SVM [Support Vector Machine])进行了训练和优化。模型性能评估基于鉴别(AUC[曲线下面积],准确性,f1评分),校准(Brier评分,校准斜率)和临床实用性。在一个独立的外部中国队列(n = 273, 2020-2024)上进一步验证了表现最好的模型。结果研究队列的平均年龄为62.8岁,30天死亡率为19.9%(410/2060)。非幸存者明显更老,有更高的合并症负担,更严重的生理紊乱。LASSO分析确定了16个预后变量,其中年龄、血液学参数(RDW、WBC)、SOFA评分、血流动力学测量(SBP)和抗高血压治疗成为重要的预测因素。在所有模型中,CatBoost算法在内部验证集中表现优异,AUC(0.955)、准确率(0.884)和f1评分(0.878)最高,校准效果也很好(Brier评分:0.081)。随后构建了一个软投票集成模型,该模型集成了前三种算法(CatBoost、RF、SVM)。在外部验证中,该集成模型具有鲁棒性泛化,保持了较强的判别性(AUC: 0.842,准确度:0.737)和校准性(Brier评分:0.173),优于独立的CatBoost模型。SHapley加性解释分析提供了可解释的、个性化的风险评估。本研究训练、优化并评估了一种高性能的基于ml的骨科创伤和脓毒症患者30天死亡率预测模型。CatBoost模型和软投票集合,特别是后者,显示出很强的通用性和临床实用性,为这一弱势群体的早期风险分层和个性化管理提供了潜在的工具。

Background
Perioperative bleeding is a major challenge in coronary artery bypass grafting (CABG). Existing bleeding risk models often lack specificity for off-pump CABG (OPCABG) patients.
Objective
This study aims to develop and validate a novel perioperative bleeding prediction model tailored for OPCABG patients.
Methods
This retrospective, multi-center cohort study was conducted using both internal and external validation cohorts. Fourteen different models, including Binary Logistic Regression, Random Forest, Decision Tree, Extra Trees, Adaptive Boosting, Extreme Gradient Boosting, Categorical Boosting, Gradient Boosting, Naive Bayes, Artificial Neural Network, Light Gradient Boosting Machine, K-nearest Neighbors, Support Vector Machine, and LogitBoost, were applied for model development. SHapley Additive exPlanations (SHAP) were used to interpret feature importance and the model’s outputs.
Results
The final model, CABG Bleeding Risk of 10 Variables (CABG-BR10), was built using Random Rorest. This model identified 10 key variables: antiplatelet drug discontinuation, N-terminal pro B-type natriuretic peptide, activated partial thromboplastin time, hemoglobin, urea, cardiac troponin T, estimated glomerular filtration rate, total bilirubin, fibrinogen, and international normalized ratio. In the internal and external validation cohorts, the model demonstrated solid performance with Receiver Operating Characteristic − Area Under the Curve values of 0.90 and 0.87, and Precision-Recall − Area Under the Curve values of 0.70 and 0.67, respectively. SHAP analysis identified key predictors of bleeding risk, and an online tool was developed to facilitate bleeding risk assessment.
Conclusion
The CABG-BR10 model accurately predicts perioperative bleeding risk in OPCABG patients, outperforming traditional scoring systems and providing interpretable, clinically relevant insights into bleeding risk factors.

Objective
This study aimed to create and validate a machine learning (ML) model to predict the likelihood of invasive mechanical ventilation (IMV) in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) complicated by respiratory failure.
Methods
Data from patients diagnosed with AECOPD and respiratory failure were retrospectively extracted from the Medical Information Mart for Intensive Care-IV (MIMIC-IV). A total of 551 cases were split 7:3 into a training set (385 cases) for model construction and an internal validation set (166 cases). The IMV served as the outcome event. Features were selected with the Boruta algorithm and least absolute shrinkage and selection operator (LASSO). Eight ML algorithms—XGBoost, decision tree (DT), random forest (RF), support-vector machine (SVM), LightGBM, CatBoost, Gaussian naïve Bayes (NB) and K-nearest neighbor (NN)—were trained with 10-fold cross-validation. Model performance was assessed by the area under the receiver operating characteristic curve (AUC), accuracy, sensitivity, specificity, F1 score, calibration curve, decision curve and clinical impact curve. An external validation cohort of 100 AECOPD-respiratory failure patients admitted to Baoying People’s Hospital between January 2020 and August 2025 was collected. The final best model was interpreted with SHapley Additive exPlanations (SHAP) to clarify feature importance and decision logic, and an interactive dynamic nomogram was plotted to increase readability.
Results
Boruta plus LASSO identified total calcium, partial pressure of oxygen (PO2), oxygen saturation (SpO2) and sepsis as significant predictors. XGBoost outperformed the other algorithms, achieving an internal validation accuracy of 72.2 %, sensitivity of 64.6 %, specificity of 79.8 %, F1 score of 69.7 % and AUC of 0.813 (95 % CI 0.748–0.878). The external validation accuracy reached 76.4 %, the sensitivity reached 82.6 %, the specificity reached 70.0 %, the F1 score reached 78.7 %, and the AUC reached 0.840 (95 % CI 0.801–0.879). SHAP analysis further indicated that PO2 and SpO2 were the primary drivers of model decisions. An interactive dynamic nomogram was successfully constructed.
Conclusion
IMV in AECOPD patients with respiratory failure was associated with total calcium, PO2, and SpO2 levels and sepsis. The developed XGBoost model demonstrated good predictive value for IMV in this clinical population.
目的:本研究旨在建立并验证机器学习(ML)模型,以预测慢性阻塞性肺疾病(AECOPD)急性加重期合并呼吸衰竭患者进行有创机械通气(IMV)的可能性。方法:回顾性地从重症监护医学信息市场- iv (MIMIC-IV)中提取诊断为AECOPD和呼吸衰竭的患者的资料。551个案例以7:3的比例分成用于模型构建的训练集(385例)和内部验证集(166例)。国际货币基金组织会议是最后的会议。使用Boruta算法和最小绝对收缩和选择算子(LASSO)选择特征。8种ML算法——xgboost、决策树(DT)、随机森林(RF)、支持向量机(SVM)、LightGBM、CatBoost、高斯naïve贝叶斯(NB)和k近邻(NN)——进行了10倍交叉验证的训练。通过受试者工作特征曲线下面积(AUC)、准确度、灵敏度、特异性、F1评分、校准曲线、决策曲线和临床影响曲线评价模型性能。收集2020年1月至2025年8月在宝应市人民医院住院的100例aecopd -呼吸衰竭患者的外部验证队列。利用SHapley加性解释(SHAP)对最终的最佳模型进行解释,以明确特征重要性和决策逻辑,并绘制交互式动态nomogram以提高可读性。结果:Boruta + LASSO发现总钙、氧分压(PO2)、氧饱和度(SpO2)和脓毒症是显著的预测因素。XGBoost优于其他算法,其内部验证准确率为72.2%,灵敏度为64.6%,特异性为79.8%,F1评分为69.7%,AUC为0.813 (95% CI 0.748 ~ 0.878)。外部验证准确度达76.4%,灵敏度达82.6%,特异性达70.0%,F1评分达78.7%,AUC达0.840 (95% CI 0.801 ~ 0.879)。SHAP分析进一步表明,PO2和SpO2是模型决策的主要驱动因素。成功地构造了一个交互式动态图。结论:AECOPD合并呼吸衰竭患者IMV与总钙、PO2、SpO2水平及脓毒症相关。开发的XGBoost模型在该临床人群中显示出良好的IMV预测价值。

Objective
Eye-tracking technology has been increasingly investigated as an objective approach for distinguishing individuals with Autism Spectrum Disorder (ASD) from typically developing (TD) individuals. Artificial intelligence and machine learning (ML) methods have been widely applied to support ASD diagnosis and treatment, and prior studies suggest that ML models leveraging eye-tracking data can achieve high diagnostic accuracy. This systematic review and meta-analysis aimed to evaluate the diagnostic performance of machine-learning models using eye-tracking data to distinguish children and adolescents with ASD from TD peers.
Methods
We systematically searched PubMed, Embase, Web of Science, IEEE Xplore, Scopus, and the Cochrane Library from inception to August 3, 2025. We included studies that applied ML methods to eye-tracking data to distinguish children with ASD from TD children. We extracted data on participant characteristics, model performance, eye-tracking protocols, and machine-learning algorithms. The review protocol was registered in PROSPERO (CRD420251162462).
Results
We identified 1,045 records, of which 25 studies were included in the meta-analysis. The included studies comprised 2,319 participants, with sample sizes ranging from 32 to 529 per study. The pooled accuracy, sensitivity, and specificity of machine-learning models using eye-tracking data to distinguish children with ASD from TD children were 85 % (95 % CI, 81–89 %), 86 % (95 % CI, 82–89 %), and 86 % (95 % CI, 79–91 %), respectively. These results suggest that eye-tracking–based machine-learning approaches have good diagnostic performance for identifying ASD.
Conclusion
Eye-tracking–based machine-learning approaches show considerable potential for distinguishing children with ASD from TD children. However, the robustness and generalizability of these findings are limited by the lack of external validation, small sample sizes, and substantial between-study heterogeneity. To establish generalizability, future research should prioritize standardized eye-tracking paradigms and large-scale, prospective, multicenter study designs with external validation. Such efforts may facilitate the translation of these models into clinical practice as objective and efficient adjunctive screening tools.
