Although the bispectral index (BIS) monitor is the golden standard system for the DoA monitoring, it is still not affordable for the developing countries. Alternatively, a low-cost electroencephalogram (EEG) headband can be used. The objective of this paper is to present a new algorithm for estimating the BIS values using a single frontal EEG channel. Method: In the first step, the EEG signal is filtered for the elimination of artifacts and is split into its sub-bands. In the second step, several linear and nonlinear features are extracted from each sub-band and fed to a random forest regression model in order to estimate the BIS. The performance of the proposed algorithm is assessed using EEG data recorded from twenty-four subjects during the general anesthesia and is validated in terms of correlation coefficient (CC) and absolute error (AE) between the reference and estimated BIS values. Results: The proposed algorithm achieved the mean CC of 0.83 and AE of 6.5 for intra subject variability and mean CC of 0.87 and AE of 5.5 for inter subject variability. Significance: Given the similar results for both intra and inter subject variability, the proposed algorithm has the potential to be used in the real-world scenario.","PeriodicalId":191927,"journal":{"name":"2023 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132672985","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}

Therefore, we propose a technique for the assessment of ER using the measurement of local pulse wave velocity (PWV) during reactive hyperemia (RH). Continuous diameter and flow velocity were recorded on 10 healthy subjects during baseline, RH and recovery phases and corresponding PWV was calculated using the flow-area (QA) and ln(diameter)-velocity (DU) method. After $54pm 32s$ of cuff release, PWV increased to 35.53% and 18.45% compared to baseline, and recovered to 45.6% and 55.62% from RH in $78pm 16s$ for both QA and DU methods. The study was repeated for 2 consecutive days. Repeatable diameter and flow measurements were obtained $(ICC 0.6)$. There existed a significant mean difference in estimation of PWV using QA and DU methods $(P0.05)$. The ICC for PWV derived ER was 30% higher than FMD%. Hence, analyzing temporal response of local PWV to ischemia is a reliable technique for assessment of ER. Direct methods for evaluating PWV during the course of the experiment can be a potential and simpler technique for assessment of ER.","PeriodicalId":191927,"journal":{"name":"2023 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132910597","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 results showed that the hand identification is not influenced by the presence of the racket, but it is heavily influenced by the speed of the hand. Moreover, the errors in contact detection were $-0.01pm 0.12mathrm{~s}$ for start and $0.00pm 0.12mathrm{~s}$ for end of contact (mean pm standard deviation), with a RMSE of 0.12s for both with a slight improvement when the racket is present and no significant differences between the tests executed at sub-maximal speed and maximal speed.

The time taken for caffeine to act on the body varies from person to person. This study is aimed to see the short-term effects of caffeine supplements (200 mg/capsule) on Heart Rate Variability (HRV) considering this individualised response to caffeine. Thirty healthy subjects participated in the study (Female:10, Male:20, Age:24.60 ± 3.02). The ECG data of the subjects were collected using the platform ‘Repose’ by Netrin Sports Technologies, India. The duration after the caffeine intake of two hours was divided into smaller time windows (30mins) to closely observe how HRV changed. The study used Kubios Standard software (version 3.5.0) to analyse time-domain HRV parameters, frequency-domain HRV parameters and autonomic nerve indexes before and after the intervention. Questionnaires were used to understand the subjects’ caffeine tolerance and habits and to understand the subjects’ psychological state during the study. It was found that the subjects’ parasympathetic activity improved after caffeine intake, resulting in better HRV parameters and autonomic nerve indexes. The HRV was found to peak after a particular time post the intake, and this time varied from person to person. Statistically significant changes were observed in RMSSD, pNN50, HR, LF/HF, SI and PNS after caffeine intake (p<0.05). No significant changes were found in SDNN.","PeriodicalId":191927,"journal":{"name":"2023 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124537035","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}

In this context, there is an increasing demand for wearable devices that can potentially provide heterogeneous information about the athlete’s health state, with the challenge of meeting the athlete’s needs in terms of comfort.In this paper, we propose a low-cost and unobtrusive wearable smart vest and a related adaptive algorithm to estimate both physiological variables such as heart rate (HR) and respiratory rate (RR) and the pace cadence. The sensing part of our smart vest consists of a single Inertial Measurement Unit (IMU) embedding both an accelerometer (ACC) and a gyroscope (GYR) positioned on the thorax of the subject. Our device was tested on four volunteers during both at-rest postures, walking and running at different speeds. Results show that the GYR outperforms the ACC for both HR and RR estimation during at-rest postures taken up before performing the running exercise. Average Mean absolute error (MAE) values of 1.22 bpm and 0.39 bpm have been achieved for ACC and GYR in HR monitoring in the pre-exercise phase; Average MAE of 3.59 breaths/min and 0.36 breaths/min have been achieved for ACC and GYR in RR monitoring in pre-exercise phase. Also, after the exercise protocol, the results are very promising, with average MAE of 0.24 bpm and 0.25 bpm using ACC and GYR for HR estimation and up to 1.60 breaths/min and 0.15 breaths/min for ACC and GYR in RR monitoring, respectively. Moreover, the pace cadence estimated by our system matches all the protocol phases required for the volunteer. The obtained results support the feasibility of estimating HR, RR, and cadence by using the sensors inside the smart vest in daily life and sports activities.","PeriodicalId":191927,"journal":{"name":"2023 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125018215","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}

Accordingly, the importance of indoor air quality management and the need for regulations have emerged, and various indoor air quality management activities such as ventilation and mask wearing have been carried out. However, unlike these efforts, real-time analysis of internal airborne bioaerosols still needs a lot of improvement. The naturally very low concentration of bioaerosols makes them unsuitable for existing biosensor research in development, which requires highly concentrated liquid samples. Therefore, it is necessary to collect high concentration of bioaerosol with liquid form in real time. In this study, by utilizing cyclone sampler, continuous sampling obtaining highly concentrated bioaerosol sample can be achieved rather than the existing discontinuous impactor method, and a study was conducted to implement real-time analysis based on silicon nanowire biosensor. Structural optimization was performed based on computational fluid dynamics analysis of the air flow inside the bioaerosol sampler, and the performance was investigated using Aspergillus niger fungus and standard particles, which show a low cut-off size of 0.5 um. Finally, possibility of real-time analysis was confirmed through continuous collection test. The proposed technology is expected to make a significant contribution to the systematic management of indoor air quality management and the prevention of respiratory diseases through linkage with internet of things technology.","PeriodicalId":191927,"journal":{"name":"2023 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116229279","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}

However, manual cover slipping relies heavily on the expertise of the histologist and can be time-consuming, while commercially available automated cover-slippers are limited to handling only 1” x 3” slides suitable for small tissue sizes. For large tissue sections extracted from brain, liver, and other organs, handling large-format slides, cover slips, and dispensing the optimal amount of mounting media can be challenging. To address this challenge, we developed SLIDE PROTEKT, an automated cover-slipper system that can handle slides of sizes 6” x 8”. The reliability of the system to effectively handle large cover slips and dispense the mounting media was validated and the results are presented in this paper. The cover slip pickup mechanism had an 84% accuracy in picking cover slips without misalignments or deformations. The pressure required to pick and hold the cover slip effectively was found to be 15 kilopascals. For large format 6” x 8” slides, the optimal mounting media volume required was 5 milliliters which the system consistently dispensed with a mean error of 4.2%.

However, electrical stimulation can also promote blood circulation, increasing oxygen saturation (SpO2). This study developed a method that entails using two-dimensional (2D) SpO2 images to analyze the effectiveness of microcirculation promotion in the hand after electrical stimulation performed using NCS equipment. The stimulation current and duration were varied, and SpO2 was measured after each stimulus (count). The results revealed that SpO2 tended to increase before returning to baseline. In one experiment, SpO2 increased by approximately 3%–4% after three counts and returned to baseline after four more counts. The proposed 2D SpO2 observation method was effective for determining the influence of the NCS process on microcirculation promotion, and the results can be used by clinical rehabilitation physicians for limb numbness treatment.","PeriodicalId":191927,"journal":{"name":"2023 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116833933","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 main aim of the study is to develop a simple automatic approach for the assessment of the tooth demineralization, which represents the earlier stage of the dynamic carious process, by means of impedance spectroscopy. In particular, impedance measurements were carried out on 50 extracted human teeth. Teeth were demineralized in-vitro according to a validated protocol; then, a morphological analysis of the tooth surface was performed by scanning electron microscopy to confirm enamel demineralization. The proposed approach tries to take advantage of the change of impedance phase due to the demineralization process. Data analysis confirmed that the best frequency for discriminating between demineralized and non-demineralized teeth is about 15 Hz, and this parameter can be used for building up an automatic classifier based on Multilayer Perceptron (MLP) topology. Impedance data were processed by using a modified single neuron, which allows classifying demineralized and sound teeth with an error rate of about 7%, estimating therefore the presence of carious lesions in progress.

According to a 2020 report by the World Health organization, an estimated number of 1.3 million to 3.9 million newborns suffer from sepsis each year, and 4.0 million to 7.0 million die from sepsis-related complications. A newborn with an infection will show signs or changes in their appearance. Symptoms like temporary acceleration or slowing of the heart rate, and low HRV, are commonly associated with neonates who have sepsis Accurate detection of heart rate anomalies is essential for diagnosing sepsis. In this study, heart rate abnormality encompasses low HRV, transient acceleration or slowing of the heart rate, and other unusual events. The current methods of clinical observation of abnormalities are not necessarily intuitive or informative. For example, differentiation between proven sepsis and culture-negative sepsis is difficult by solely observing the average heart rate on a bedside monitor. To this end, we proposed a new visualization tool to help clinicians in the detection of suspected false-positive neonatal sepsis. Our visualization tool provides information such as the variability and distribution of the heart rates, which can be used to detect the abnormal events. These functions will help clinicians to detect possible false-positive sepsis and reduce unnecessary antibiotic treatment.","PeriodicalId":191927,"journal":{"name":"2023 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126813085","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}
