In this paper, simulations and experiments were performed to investigate the efficacy of the temperature-feedback control system in confining the thermal damaged area and in maintaining the setpoint temperature. The implemented control system adjusts the laser source power based on the maximum temperature values measured by fiber Bragg grating sensors. The theoretical model predicts the thermal response of the biological tissue under different control parameters and allows calculating the produced thermal damage. Different setpoint temperatures ranging from 43 °C to 60 °C were chosen to evaluate their effects on the irradiated tissue region, in terms of temperature trend and thermal damage. The numerical results are validated by the experimental temperature trends obtained applying the same control strategy. Finally, both the simulation results and experiment outcomes show the capability of the control system to confine the tissue thermal damaged area by performing a laser ablation procedure almost at the set temperature.","PeriodicalId":429222,"journal":{"name":"2021 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122573325","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}

Then, such interaction was measured through a complexity index as Lemepel-Ziv. The method proposed would overcome some limitations that classical posturographic data analysis encounters in underlining differences among groups of subjects. This aspect is of great interest in the assessment of pathologies that affect the nervous system and its balance control strategies. The discriminative capability of the proposed method was evaluated through two assessments: the first aimed to highlight differences between young and elderly subjects; the second, more challenging, required to highlight differences between diabetic patients without neuropathy and diabetic patients with asymptomatic neuropathy. Wilcoxon-Mann-Whitney tests revealed that CTK combined with Lempel-Ziv index significantly differentiate the groups in the two assessments.","PeriodicalId":429222,"journal":{"name":"2021 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127989660","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}

Using sensors is not common because of the limitations of catheters and complications related to the safety of patients. In this regard, a sensor free method can be deemed as a safe solution, in which it uses available equipment in the real operation room. In this work, we propose a deep learning method to estimate the contact forces directly from the catheters’ image tip without embedding further sensors. A convolutional neural network extracts the catheter’s deflections through input images and translates them into the corresponding forces. The architecture of the proposed model has been inspired by the ResNet graph so as to perform a regression. The model can make predictions based on the input images without utilizing any feature extraction or preprocessing steps. An experimental setup was designed and implemented to simulate catheter ablation therapy. Evaluation results show that the proposed method is able to elicit a robust model from the given dataset and approximate the force with proper accuracy. Opting RMSE as the preferred performance metric, the model reached 0.028 N and 0.023 N in estimation error in the x and y direction on the test data set, respectively.","PeriodicalId":429222,"journal":{"name":"2021 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133799501","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 order to control their toxicity and release, the CuO NPs were encapsulated within polymeric nanospheres composed of poly(lactic-co-glycolic acid) (PLGA) core and polydopamine (PDA)/polyethylene glycol (PEG) shell. After the characterization of synthesized nanospheres, their photothermal response to different near-infrared laser sources (808 nm, 940 nm and 1064 nm) was assessed in terms of the measured temperature. Arrays of sub-millimetric fiber Bragg grating sensors were employed to achieve an optimal spatial resolution for resolving the temperature increase in samples embedding the nanospheres. The results have shown that the designed structure of CuO@PLGA/PDA/PEG nanospheres substantially augments the temperature elevation. A maximum of 30 °C temperature increase, in comparison with the control solution, was achieved for the 808 nm laser source. These results indicate that the designed structure of CuO@PLGA/PDA/PEG nanospheres is suitable for further applications towards chemo-photothermal therapy combined with diagnostic imaging for the treatment of cancer.","PeriodicalId":429222,"journal":{"name":"2021 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131742572","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 achieve this goal, one option could be non-contact sensor arrays that measure vital signs. In this work, we present initial results for the assessment of heart rate through video magnification techniques applied to visible light Red/Green/Blue (RGB) video recordings of the face. The work specifically explores the effect of region of interest size on the accuracy of heart rate measurements. The visible skin on a person’s face can be obscured by hair or face masks, leading to a need for algorithms and methods that can compensate for these effects. The results show the potential for the combination of many small regions as an alternative to a single large region. The best performance for small regions is a mean absolute error of 9.9% while larger regions performed better with the best error performance of <3%. The work also shows that for larger regions covering most/all of the face, body motion reduces the performance more than the use of a face mask that obscures a portion of the face. This work provides the foundation for further development of robust non-contact health screening solutions.","PeriodicalId":429222,"journal":{"name":"2021 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130944199","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}

CysC is a small protein that can be expressed by all nucleated cells. It is rarely influenced by factors other than Glomerular filtration rate (GFR), an indicator of renal function chronic kidney diseases (CKD). That makes it a reliable biomarker for the measurement of the GFR. Aptamers bind specifically to the target molecules, it is less expensive, more stable, and lack immunogenicity. The aptamers became a valuable tool in clinical diagnosis and made them a great alternative to antibodies. In this study, we designed and developed an aptamer- antibody pair-based quantitative lateral flow assay for the CysC quantification in the human sample. A highly sensitive and specific CysC sensor was achieved by conjugating CysC selective aptamers to the organic dye Alexafluor-647. When CysC molecules are present in the sample, they form a complex with the designed aptamers to bind, especially with the CysC antibody immobilized on the lateral flow assay strip's test zone. Important parameters that influence the sensitivity in lateral flow assay, such as the concentration of aptamers in the conjugation pad, were evaluated to give the optimum assay performance. The assay was precise and has a limit of detection of 0.013 µg/µl was shown better than the antibody-based kit. In summary, the resulting LFA aptamers-based sensor provides a rapid, sensitive, cost-effective point of care sensor for CysC detection in human samples.","PeriodicalId":429222,"journal":{"name":"2021 IEEE International Symposium on Medical Measurements and Applications (MeMeA)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132365034","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}
