Kecheng Lai, Yuqi Liu, Takehiro Iino, T. Fujinami
This study aimed to determine whether intuitive play in a real environment affects the cerebral blood flow during the interaction between individuals. We implemented a creativity-related task designed by Cheng and Hashimoto. We focused on using fNIRS technology to investigate the differences between two ways for collaborative problem-solving, namely, do-first and think-first approaches. We obtained significant differences between the activities referring to ideas and the others interpreting concepts. We found that the "do-first" approach facilitates conversations on ideas, which reproduced Cheng and Hashimoto's experiment. We also saw a trend of increased cerebral blood flow in the subjects' prefrontal cortex and increased brain activity when performing the task. Our findings indicate that fNIRS technology enables us to study the mechanism of idea generation.
本研究旨在确定在真实环境中的直觉游戏是否会影响个体之间互动时的脑血流量。我们执行了Cheng和Hashimoto设计的一个与创造力相关的任务。我们专注于使用近红外光谱技术来研究两种协作解决问题的方法之间的差异,即行动优先和思考优先方法。我们发现,在涉及想法的活动和其他解释概念的活动之间存在显著差异。我们发现,“行动优先”的方法促进了关于想法的对话,这复制了Cheng和Hashimoto的实验。我们还发现,在执行任务时,受试者前额叶皮层的脑血流量有增加的趋势,大脑活动也有所增加。我们的研究结果表明,fNIRS技术使我们能够研究想法产生的机制。

Hypertension Disease Predictions with Various Models Using Data Science Framework 使用数据科学框架的各种模型预测高血压疾病
Azadeh Alizargar, Tan-Hsu Tan, Yang-Lang Chang, Mohammad Alkhaleefah
Hypertension is a common disease which may lead to incurable situation if it is not well-treated. By extracting knowledge from large datasets, data mining can be used for the hypertension prediction and diagnosis. In this research, three data mining techniques, the support vector machine (SVM), k-nearest neighbors (k-NN), and decision tree, were developed to predict the hypertension with two datasets. These techniques were implemented on Google Colab using Python codes. Experimental results illustrate that the accuracy and area under the receiver operating characteristic (ROC) curve performance of all these three techniques on first dataset is 81% and 80.64% for the SVM, 74% and 73.97% for the k-NN, and 74% and 73.86% for the decision tree, respectively. The accuracy and ROC curve performance of these three approaches on the second dataset were 73% and 72.48% for the SVM, 76% and 75.75% for the k-NN model, and 75% and 74.49% for the decision tree, respectively. The results indicate that the SVM, k-NN, and decision tree, are effective in predicting the hypertension based on the obtained important features of the patients, and the k-NN is among the best choice.
高血压是一种常见病,如果治疗不好,可能会导致不治之症。通过从大数据集中提取知识,数据挖掘可以用于高血压的预测和诊断。本研究采用支持向量机(SVM)、k近邻(k-NN)和决策树三种数据挖掘技术,对两组数据集的高血压进行预测。这些技术是在Google Colab上使用Python代码实现的。实验结果表明,这三种方法在第一个数据集上的准确度和ROC曲线下的面积分别为支持向量机的81%和80.64%,k-NN的74%和73.97%,决策树的74%和73.86%。这三种方法在第二个数据集上的准确率和ROC曲线性能分别为SVM的73%和72.48%,k-NN模型的76%和75.75%,决策树的75%和74.49%。结果表明,支持向量机、k-神经网络和决策树能够有效地预测高血压患者的重要特征,k-神经网络是最佳选择之一。

The development and implementation of deep learning assisted interoperable retinal image structured report module in PACS PACS中深度学习辅助互操作视网膜图像结构化报告模块的开发与实现
Jin Li, Jiahui Shao, J. Wu, Jinxia Fang, Tongtong Zhou, Huiqun Wu
With the increasing incidence of retinal fundus disease, more attention has been paid to the screening and prevention of fundus diseases. However, the low efficiency and interoperability issues hinder the application of retinal disease reporting. In this study, we developed an intelligent classification module for retina based on inception V3 pre-trained model. The top rank of eight classification scores was output as recommendation for image reader reviewing, and the other structured report (SR) module was designed to generate FHIR-compliant retinal diagnostic SRs by customizing existing FHIR DiagnosticReport and Observation resources. The results demonstrated the artificial intelligence (AI) classification pop-up window and the validation of produced SR via a public HAPI FHIR server. The results suggested that the SR was easily shared and could be accurately and integrated with other hospitals or clinical research institutions. In summary, our developed AI assisted SRs module is clinical workflow friendly, and the produced SRs could be easily shared and integrated, which can provide a meaningful use way for further analytic research.
随着视网膜眼底疾病发病率的不断上升,人们越来越重视眼底疾病的筛查和预防。然而,低效率和互操作性问题阻碍了视网膜疾病报告的应用。在本研究中,我们开发了一个基于inception V3预训练模型的视网膜智能分类模块。输出8个分类得分的最高排名作为推荐给图像阅读器评审,另一个结构化报告(SR)模块通过定制现有的FHIR诊断报告和观察资源来生成符合FHIR的视网膜诊断报告。结果显示了人工智能(AI)分类弹出窗口,并通过公共HAPI FHIR服务器验证了生成的SR。结果表明,SR易于共享,可与其他医院或临床研究机构准确整合。综上所述,我们开发的人工智能辅助SRs模块对临床工作流程友好,并且生成的SRs易于共享和集成,为进一步的分析研究提供了有意义的使用方式。

CBRN Weapons as a Threat to Critical Infrastructure Elements CBRN武器对关键基础设施构成威胁
K. Vichova, M. Hromada, Frantisek Paulus, J. Valasek
Disruption of the critical infrastructure element can seriously impact the security of the state, the necessities of the population, and the state's economy. One essential element of infrastructure is healthcare. Due to the large concentration of inhabitants, the healthcare system can target terrorist attacks. These attacks may be by chemical, biological, radiological, and nuclear (CBRN) weapons. The aim of the paper is to assess the hospital's preparedness to solve terrorist attacks. Secondly, the case study for the selected hospital in the Czech Republic was prepared. Heuristic preparedness analysis and TerEx software were selected for the preparing results. Based on the analytical method, we get an idea of the preparedness system to solve terrorist attacks in hospitals and vulnerabilities. TerEx software is used for the mathematical model of the case study. The preparedness of individual hospitals varies in the Czech Republic. Therefore, it is essential that hospitals, as elements of critical infrastructure, reduce the risk of terrorist attacks using CBRN weapons.
关键基础设施要素的中断可能严重影响国家的安全、人口的必需品和国家的经济。基础设施的一个基本要素是医疗保健。由于居民的高度集中,医疗保健系统可以成为恐怖袭击的目标。这些攻击可能是化学、生物、放射性和核(CBRN)武器。本文的目的是评估医院应对恐怖袭击的准备情况。其次,为选定的捷克共和国医院编写了案例研究。准备结果采用启发式准备分析和TerEx软件。基于分析方法,提出了应对医院恐怖袭击的防范体系及其脆弱性的思路。使用TerEx软件进行数学模型的案例研究。捷克共和国各医院的准备情况各不相同。因此,医院作为关键基础设施的组成部分,必须减少使用生化武器进行恐怖袭击的风险。

Developing a GraphQL SOAP Conversational Micro Frontends for the Problem Oriented Medical Record (QL4POMR) 面向问题的病案(QL4POMR)的GraphQL SOAP会话微前端开发
Sabah Mohammed, J. Fiaidhi, Darien Sawyer, Mehdi Lamouchie
Healthcare institutions are slowly starting to deploy chatbots as a new method of communication with their patients. However, most of the automated chatbots fails to satisfy the patient expectation. Moreover, the idea of simulating a conversation similar to how the physician-patient interact when a patient encounter a health issue is not fully understood and implemented. Due to the infancy and lack of research on building such conversational chatbots that can work together to seek information and to answer queries related to a patient encounter and record it using a clinical charting format like SOAP, the purpose of this paper is to describe our attempt and the architecture that we build using the AWS AppSync which has been integrated with our QL4POMR medical record system. We are attempting to use the prototype to learn the limitations regarding it usability at different clinical practices. Additional constructs or artificial intelligence techniques could be used to obtain higher acceptability and to fit specific clinical practices.
医疗机构正慢慢开始部署聊天机器人,作为一种与患者沟通的新方法。然而,大多数自动聊天机器人都不能满足患者的期望。此外,当病人遇到健康问题时,模拟类似于医患互动的对话的想法还没有完全被理解和实现。由于构建这样的会话聊天机器人的研究尚处于初级阶段和缺乏,这些聊天机器人可以一起寻找信息,回答与患者遇到的问题相关的查询,并使用SOAP等临床图表格式进行记录,因此本文的目的是描述我们的尝试以及我们使用AWS AppSync构建的架构,该架构已与我们的QL4POMR医疗记录系统集成。我们正在尝试使用原型来了解它在不同临床实践中可用性的局限性。其他结构或人工智能技术可用于获得更高的可接受性,并适合特定的临床实践。

P. Permatasari, Cahya Arbitera, Dwi Mutia Wenny
Citizens are people who have a high risk of exposure to diseases due to unhealthy environmental conditions. This requires citizens to take advantage of health services in order to get optimal examinations. The purpose of this study was to determine the description and relationship between the characteristics of citizens and the utilization of health services by citizens in the area of Indonesia in 2020. The quantitative research method with cross- sectional design used random sampling techniques. The number of samples was 150 families in the area of Tangerang Selatan, Indonesia. Measuring instrument in the form of a questionnaire with data collection techniques in the interviews form. Data analysis used chi-square analysis and multiple logistic regression analysis. The results showed that the variables related to the utilization of health services were knowledge variable (p = 0.001), number of families (p = 0.021), perception of pain (p = 0.001), and family support (p = 0.030). And the variables that were not related to the utilization of health services were ownership of health insurance (p = 0.750), transportation (p = 0.297). As well as the dominant variable related to the utilization of health services, that is knowledge (p = 0.000) with OR 12.876. It is hope that prima Wry health care and health workers can involve more communities around the area in their work programs, such as providing health information.

Choice variation on electronic health database: a case study of medical decision mapping from healthcare scheme of Thailand 电子健康数据库的选择变异:以泰国医疗保健计划医疗决策映射为例
P. Tansitpong
The goal of this study is to develop a model for tracking and monitoring medical records in hospitals with limited database and computing resources. Electronic health records were collected from regional hospitals in Thailand with prescribing guidelines from the national public health administration, as health care management is complicated by a wide range of drug options and a wide range of health benefit options. The cost of treatment for patients with chronic diseases was also significantly higher than for patients with other diseases, according to the regression analysis. Patients with universal coverage plans have seen lower healthcare costs as a result of regulations and differentiation in the service of multiple health benefit programs.
本研究的目的是开发一个模型,用于在数据库和计算资源有限的医院中跟踪和监测医疗记录。电子健康记录是根据国家公共卫生管理部门的处方指南从泰国的区域医院收集的,因为医疗保健管理因各种各样的药物选择和各种各样的健康福利选择而复杂化。根据回归分析,慢性疾病患者的治疗费用也明显高于其他疾病患者。由于多种健康福利计划的规定和服务的差异化,享有全民保险计划的患者看到了较低的医疗费用。

Vibrotactile Motion Guidance for Stroke Rehabilitation: A Comparative Study 振动触觉运动指导在脑卒中康复中的比较研究
Tim Moesgen, Antti Salovaara, Emmi Pouta, Rebecka Pyykko, Yu Xiao
Stroke is one of the most common causes of death globally and a reason for severe impairments. Many stroke survivors report a loss of muscle strength and, thus, need to regain motor control of their upper limbs with rehabilitation. In some cases, patients may compensate for muscle weakness with harmful compensatory movements using other muscles. We envision that VR-based training can provide multimodal feedback during sensorimotor training to avoid compensatory movements. However, feedback may be hampered by changes in patients’ somatosensory system, resulting in both weakened and intensified tactile perceptions. We explored the differences in perception of vibration metaphors for motion guidance between healthy participants and stroke patients and assessed the efficiency of multimodal feedback for the correction of arm trajectory. Multimodal stimuli for trajectory correction benefited the patients but there were also differences in their tactile perception.

中风是全球最常见的死亡原因之一,也是造成严重损伤的原因之一。许多中风幸存者报告肌肉力量丧失,因此需要通过康复来恢复对上肢的运动控制。在某些情况下,患者可能会使用其他肌肉进行有害的代偿运动来补偿肌肉无力。我们设想基于vr的训练可以在感觉运动训练中提供多模态反馈,以避免代偿运动。然而,反馈可能会受到患者体感系统变化的阻碍,导致触觉感知减弱或增强。我们探讨了健康参与者和脑卒中患者在运动指导中振动隐喻感知的差异,并评估了多模态反馈对手臂轨迹校正的效率。多模态轨迹矫正刺激对患者有益,但在触觉感知方面也存在差异。这些针对患者的研究结果要求患者参与触觉康复设备的设计过程,遵循以患者为中心的医疗保健建议。

Many stroke survivors report a loss of muscle strength and, thus, need to regain motor control of their upper limbs with rehabilitation. In some cases, patients may compensate for muscle weakness with harmful compensatory movements using other muscles. We envision that VR-based training can provide multimodal feedback during sensorimotor training to avoid compensatory movements. However, feedback may be hampered by changes in patients’ somatosensory system, resulting in both weakened and intensified tactile perceptions. We explored the differences in perception of vibration metaphors for motion guidance between healthy participants and stroke patients and assessed the efficiency of multimodal feedback for the correction of arm trajectory. Multimodal stimuli for trajectory correction benefited the patients but there were also differences in their tactile perception.

A Mobile Application for Chronic Kidney Disease (CKD) Diagnosis 慢性肾脏疾病(CKD)诊断的移动应用程序
K. Periyasamy, A. Kaivelikkal, V. Iyer
Chronic Kidney Disease (CKD) is a condition where kidneys partially work in filtering waste products from blood. In most cases, CKD patients do not experience any symptoms in the early stages. This makes early detection of CKD much harder. The result is starting treatment at a later stage which not only complicates the health condition of the patient, but it also increases the healthcare cost for the patient. This paper describes a mobile application the authors have developed which can be used by any healthcare practitioner. In addition to detecting the presence and the stage of CKD, the application also lets the user find out two risk factors associated with CKD patients, namely Anemia and Mineral Bone Disease (MBD). After detecting either or both of these risk factors, the tool recommends initial treatment plans for the same based on guidelines provided the National Kidney Foundation (NKF) in the United States.
慢性肾脏疾病(CKD)是一种肾脏部分过滤血液废物的疾病。在大多数情况下,CKD患者在早期阶段没有任何症状。这使得早期发现慢性肾病更加困难。其结果是在较晚的阶段开始治疗,这不仅使患者的健康状况复杂化,而且还增加了患者的医疗保健费用。这篇论文描述了一个移动应用程序的作者已经开发,可以由任何医疗从业者使用。除了检测CKD的存在和分期外,该应用程序还可以让用户发现与CKD患者相关的两个危险因素,即贫血和矿物质骨病(MBD)。在检测到这两种风险因素中的一种或两种后,该工具根据美国国家肾脏基金会(NKF)提供的指南,推荐相应的初始治疗计划。
