A Privacy-Strengthened Scheme for E-Healthcare Monitoring System

Recent Advances in Wireless Body Area Networks (WBANs) offer unprecedented opportunities and challenges to the development of pervasive electronic healthcare (E-Healthcare) monitoring system. In E-Healthcare system, the processed data are patients' sensitive health data that are directly related to individuals' privacy. For this reason, privacy concern is of great importance for E-Healthcare system. Current existing systems for E-Healthcare services, however, have not yet provided sufficient privacy protection for patients. In order to offer adequate security and privacy, in this paper, we propose a privacy-enhanced scheme for patients' physical condition monitoring, which achieves dual effects: (1) providing unlinkability of health records and individual identity, and (2) supporting anonymous authentication and authorized data access. We also conduct a simulation experiment to evaluate the performance of the proposed scheme. The experimental results demonstrate that the proposed scheme achieves better performance in terms of computational complexity, communication overheads and querying efficiency compared with previous results.     

胎心入室试验监测胎儿预后的价值

对359例临产产妇进行胎心入室试验（admissiontest），根据Ingemarsson等提出的标准将入室试验结果分为3型:反应型（正常型）、可疑型和危险型.结果显示:359例中24树新生儿窒息，窒息率为6.69％。入室试验反应型、可疑型和危险型分别为7827％、10.58％和11.14％。反应型组羊水污染率和新生儿窒息串分别为27.05％和2.85％，而危险型组分别为6750％和32.50％。两组比较差异有极显著意义（均P＜0.01）。提示:胎心入室试验可有效地预测胎儿预后，为产时胎儿监测的重要手段之一。     

胎儿心电技术在胎儿监护中的研究和应用进展

胎儿心电技术是一种新兴的胎儿监测方法。其通过基于胎儿心电技术的母胎Holter监测仪对孕妇进行持续的非产时和(或)产时胎儿心率监测,其与传统胎儿电子监护相比具有一定优势。该方法可以记录并采集胎儿心电数据,通过仪器直接得到或经过软件计算得到相关胎儿心率量化参数,并且国内外对各项量化参数的特点及其与围生儿不良结局的关系进行了相关研究,并获得一些研究成果。希望借助这种监测方法可以协助医师更准确地判断胎儿宫内情况,进而予以适当干预,降低剖宫产率,促进自然分娩,改善母儿不良预后。

Development of A Textile Capacitive Proximity Sensor and Gait Monitoring System for Smart Healthcare

Gait is not only one of the most important functions and activities in daily life but is also a parameter to monitor one‘s health status. We propose a single channel capacitive proximity pressure sensor (TCPS) and gait monitoring system for smart healthcare. Insole-type TCPS (270 mm in length) was designed consisting of three layers including two shield layers and a sensor layer. Analyzing the step count and stride time are the basic indicators in gait analysis, thus they were selected as evaluation indicators. A total of 12 subjects participated in the experiment to evaluate the resolution of our TCPS. To evaluate the accuracy of TCPS, step count and its error rates were simultaneously detected by naked eye, ZIKTO Walk (ZIKTO Co., Korea), and HJ-203-K pedometer (Omron Co., Japan) as reference. Results showed that the error rate of 1.77% in TCPS was lower than those of other devices and correlation coefficient was 0.958 (p-value?=?0.000). ZIKTO Walk and pedometer do not provide information on stride time, therefore it was detected by F-scan (Tekscan, USA) to evaluate the performance of TCPS. As a result, error rate of stride time measured by TCPS was found to be 1% and the correlation coefficient was 0.685 (p-value = 0.000). According to these results, our proposed system may be helpful in development of gait monitoring and measurement system as smart healthcare.

胎心监护预测胎儿宫内窘迫的临床应用

目的探讨胎心监测联合妊娠特异性β1糖蛋白(PSβ1G)和乳酸测定在预测胎儿宫内窘迫的临床应用。方法对产前、产时使用胎儿电子监护仪经腹壁监测胎心率和宫缩的孕妇资料进行回顾性分析,选择胎心监护异常曲线的孕妇160例作为研究对象,分为两组:PSβ1G正常组为对照组,72例;PSβ1G异常组为观察组,88例。比较两组孕妇的羊水和母血中的乳酸水平和产后异常因素。结果观察组的羊水乳酸水平高于对照组(P0.05),母血乳酸与对照组无明显差异(P0.05);观察组新生儿状况、羊水污染程度及产后异常因素均明显多于对照组(P0.05)。结论胎心监测联合PSβ1G、羊水乳酸检测能较为准确地预测胎儿宫内窘迫。

目的:探讨无应激试验(NST)、电子胎心监护及两者联合试验,对胎儿窘迫及新生儿预后评估的临床诊断价值。方法:用NST和电子胎心监护对本院120例单胎头位胎心异常的足月孕妇进行监测分析,计算两种方法单独及联合监测胎儿窘迫的灵敏度和特异性。以胎儿窘迫和新生儿窒息的判定标准为依据,作出预后评估。结果:电子胎心监护的灵敏度和特异性均高于NST,比较差异均有统计学意义(P0.05);两者联合试验诊断灵敏度和特异性均比使用上述单一监测手段的计算值偏高;胎儿窘迫组胎儿窘迫率、羊水Ⅱ~Ⅲ度粪染率以及新生儿窒息率均高于胎儿正常组,比较差异均有统计学意义(P0.05)。结论:产前NST和产时电子胎心监护均有一定的临床诊断价值,但电子胎心监护在监测的灵敏度和特异性方面更为突出,可及早诊断胎儿窘迫的发生。两者联合试验能加强监测的诊断效果,降低胎儿及新生儿的致残率与致死率,有利于改善胎儿预后。     

胎心监护的临床应用进展

胎心监护是监测胎儿宫内情况的检查之一,临床应用广泛,可实时反映胎儿生物物理活动情况,目前对其临床意义的理解及对异常情况的处理并无统一的标准。虽然临床上已广泛应用了胎心监护,但许多医师尤其是基层医院医师仍不能很好地对其监护曲线进行解读。对胎心监护的时机、指征以及胎心监护曲线结果分析等进行总结分析,有助于提高胎心监护的临床应用水平,使异常情况能尽早获得积极处理,更好地避免不必要的阴道助产及剖宫产。     

A Systematic Review for Mobile Monitoring Solutions in M-Health

A systematic review allows us to identify, assess, and interpret all possible relevant work associated with a question in particular or the subject of an area. Different authors can use several methodologies to learn about research related to their own research in different fields. The main objective of this review is to identify work, research and publications made in the field of the mobile monitoring of patients through some application or commercial or non-commercial solutions in m-Health. Next, we compare the different solutions with our solution, MoMo (Mobile Monitoring) Framework. MoMo is a solution that allows for patient mobile monitoring through mobile phones and biometric devices (blood pressure meter, glucometer and others). Our systematic review is based on the methodology of B. Kitchenham. She proposed specific guidelines for carrying out a systematic review in software engineering. We prepare our systematic review base in the selection of primary and secondary research related to mobile monitoring solutions following criteria with a specific weight to compare with each part of our research.

An IoT-cloud Based Wearable ECG Monitoring System for Smart Healthcare

Public healthcare has been paid an increasing attention given the exponential growth human population and medical expenses. It is well known that an effective health monitoring system can detect abnormalities of health conditions in time and make diagnoses according to the gleaned data. As a vital approach to diagnose heart diseases, ECG monitoring is widely studied and applied. However, nearly all existing portable ECG monitoring systems cannot work without a mobile application, which is responsible for data collection and display. In this paper, we propose a new method for ECG monitoring based on Internet-of-Things (IoT) techniques. ECG data are gathered using a wearable monitoring node and are transmitted directly to the IoT cloud using Wi-Fi. Both the HTTP and MQTT protocols are employed in the IoT cloud in order to provide visual and timely ECG data to users. Nearly all smart terminals with a web browser can acquire ECG data conveniently, which has greatly alleviated the cross-platform issue. Experiments are carried out on healthy volunteers in order to verify the reliability of the entire system. Experimental results reveal that the proposed system is reliable in collecting and displaying real-time ECG data, which can aid in the primary diagnosis of certain heart diseases.
