Alarm fatigue and desensitization leads to the death of patients, noise worsens the patient's recovery process and causes burnout syndromes of caregivers, etc. Much research has been done in the last years to reduce false alarms and noise with smart and intelligent alarm systems. However, the situation has not improved. The developed systems are not used in the field, likely due to the “better-safe-than-sorry” mentality. Thus, we state that the first step to address alarm related problems is a safe and distributed system for alarm notifications. Therefore, we present mechanisms to generate alarm notifications safely at the place where they are needed by the caregivers, that is not necessarily the bedside. Our approach holds safety, risk management, and approval requirements. We use the new IEEE 11073 Service-oriented Device Connectivity (SDC) standard family. This ensures a safe interoperability of heterogeneous devices from multiple manufacturers, which is a major technical innovation, and makes the proposed system ready for future extensions like intelligent, computer-aided assistive systems. We therefore state that our mechanisms have a high potential to be used in the field and to improve clinical problems related to alarm notification systems. A demonstrator has been implemented for the proof of concept.","PeriodicalId":120815,"journal":{"name":"2017 IEEE Healthcare Innovations and Point of Care Technologies (HI-POCT)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116240508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modern life in large cities compels people to spend less hours sleeping than they need. A wearable actigraphy that records accelerometry, light and body temperature was used to register the sleep habits of 54 healthy subjects for 14 days. From them, 28 participants resided in a town that could be regarded as a rural environment while the other subjects lived in the largest metropole of South America. The subjects filled three questionnaires to assess sleep quality (Pittsburgh Sleep Quality Index — PSQI), sleepiness (Epworth Sleepiness Scale — ESS) and chronotype (Morningness-Eveningness Questionnaire — MEQ-HO). The subjects were divided in urban and rural groups and several parameters obtained from actigraphy were compared between groups. Overall, the metropolitan group had worse sleep parameters. The total sleep time in metropolitan group was lower than the rural population, as well as the sleep quality parameters such as sleep efficiency. A possible explanation for these differences could be the social and work characteristics imposed in the metropolitan environment, forcing subjects to stay awake longer and away of natural light exposure. Sleep disorders are associated with several health and brain function problems. Therefore, it is imperative to establish changes in daily routine to promote a better sleep quality and prevent sleep disorders.","PeriodicalId":120815,"journal":{"name":"2017 IEEE Healthcare Innovations and Point of Care Technologies (HI-POCT)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114482280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current cardiac auscultation training is seeing a preference towards diagnostics equipment such as the echocardiograph that allows visualizing and listening to the heart to determine how the heart is working, rather than the use of the stethoscope which only provides auditory feedback, resulting in a loss of stethoscope-based cardiac auscultation skills which are relevant in situations where it is the only cost-effective option available. Currently, virtual reality, simulation, and games are taking a prominent role in medical training, providing consumer-level immersive and interactive realistic experiences. Within these fields, user interfaces can provide more appropriate forms of interactions for developing cognitive and psychomotor skills. However, traditional controllers are widely employed and do not map adequately the functionality of real medical equipment, including the stethoscope. In this paper, we present the development of a 3D printed stethoscope prototype for practicing virtual cardiac auscultation examination training with a mobile app. Our goal is to evaluate its usability and user preferences during a virtual examination session.","PeriodicalId":120815,"journal":{"name":"2017 IEEE Healthcare Innovations and Point of Care Technologies (HI-POCT)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129407934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research paper explains the detection process of the Cancer Antigens-CA 125 from a micro volume of the biofluid sample. The biochip is incorporated with the sensing platform in a microfluidic channel to detect the cancer antigens during the biofluid flow in the microchannel. The sensing platform is designed with multiple layers, in order to enhance the antibody immobilization on nano circuit and thus the detection signal. The antigen-antibody interaction during the biofluid flow on the immobilized antibodies in the microchannel change the capacitance measurements in the sensing circuit. The change in the capacitance indicates the targeted cancer antigens concentration in the biofluid sample. The concentration of CA-125 antigens used in the experiment is 55ug/ml at a pH of 7.4, in order to establish the functionality of the biochip. The change in capacitance after the antigen-antibody interaction is 679.62 pF is when compared to the bare electrodes. The In-situ realtime measurement of cancer biomarkers from a finger prick blood sample in a simple and easy way using the micro biochip helps to monitor the cancer progression more easily and thus enable the enhanced cancer management.","PeriodicalId":120815,"journal":{"name":"2017 IEEE Healthcare Innovations and Point of Care Technologies (HI-POCT)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127702366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ultrasonic sensor will have its respective circuit, which will issue a repetitive vibration to indicate the proximity of an obstacle, an emergency button will be implemented too, in case it is necessary, it will send a signal to a mobile device (cellphone) that can be property of a family member or of a rescue service.

Non-invasive methods have grown with popularity in determining the endothelial health as it can be safely applied on people to obtain repeated measurements of vascular function overtime. This study presents a combined non-invasive endothelial function assessment method which acquires a Peripheral Arterial Tonometry (PAT) signal and a Digital Thermal Monitoring (DTM) signal from the fingertip. The endothelium was stimulated to induce reactive hyperemia by occluding the upper arm using a blood pressure cuff. The test was carried out on 11 diabetes and 21 non-diabetes participants and the acquired signals were pre-processed and subjected to parameter calculation. A one-way ANOVA carried out on the collected multivariate data set shows that the Reflection Index, TEMP-AUC, TMP-fall and Rise/fall parameters are significant in differentiating the non-diabetes from diabetes participants. A MANOVA carried out with the 4 significant parameters identified in ANOVA indicates that, when the parameters are considered together, it has a significant effect in differentiating diabetes participants from the non-diabetes participants. It suggests that with an extensive data collection, the system can be trained to a level which could assess the level of endothelial health thus could be used as a screening system for determining the likelihood of having vascular diseases.","PeriodicalId":120815,"journal":{"name":"2017 IEEE Healthcare Innovations and Point of Care Technologies (HI-POCT)","volume":"28 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132532135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this need, an “AC electrokinetic (ACEK) capacitive sensing” method is developed that is capable of rapid, low cost and simple-to-operate specific assay for use with practical samples. The major innovation with this sensing technology is its ability to simultaneously generate ACEK effects in the fluid and to interrogate directly the sensor's interfacial capacitance. The AC signal will induce movement of proteins towards the electrode surface and accelerate the binding to immobilized probe molecules. The binding of protein is sensitively detected by monitoring the interfacial capacitance of electrode. Preliminary experiments from biological fluids yielded highly encouraging results, with limits of detection at 2.3 pg/mL measured by a benchtop instrument and around 5 pg/mL by a portable reader, which is on par with the best laboratory assay available and ours is a POC technology. This article presents the mechanisms, development and test results of this POC immunoassay.","PeriodicalId":120815,"journal":{"name":"2017 IEEE Healthcare Innovations and Point of Care Technologies (HI-POCT)","volume":"358 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122812185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
