Web-based pulse analysis system for detection of acute kidney injury 

Abstract

The purpose of pulse analysis system is to provide a platform for researchers to analyze, share, and store patients' pulse data. Researchers can use the system to extract features through Fast Fourier Transform (FFT), harmonics, Ensemble Empirical Mode Decomposition (EEMD), and then take advantage of the former result to gather statistics and classify patients through two-sample t-test or paired-sample t-test. A group of researchers working in National Taiwan University Hospital (NTUH) have done an experiment to examine whether to find out acute kidney injury (AKI) through this system is feasible. The experimental subjects were patients who received open heart surgery. The experiment result shows that after surgery the mean value of harmonic 2 and 3 of patients with postoperative AKI from the proposed pulse analysis system decreased significantly, but not in patients without AKI. This system may have a potential for clinical use to detect AKI after open heart surgery and probably other disease. However, we need more cases to verify this experiment result because the number of AKI patients is limited.

Purpose

Diabetes mellitus is a metabolic disorder of hyperglycemia and is associated with the increase in cardiovascular diseases and other complications. In traditional Chinese medicine (TCM), examination of the tongue plays an important role in diagnosis. Tongue color, tongue characteristics (e.g. petechia) and sublingual collateral vessels indicate blood stasis status in TCM. The purpose of this study was to evaluate blood stasis on tongue image and Heart Rate Variability (HRV) associated with type 2 diabetes mellitus (DM).

Methods

A total of 119 subjects with DM were enrolled for tongue examination and HRV. A high resolution digital camera was used to record tongue images in a standard imaging environment. HRV and pulse wave analysis were performed by ANSWatch. A total of 51 DM patients attended the Quality-based Payment Program for Diabetes Care and received regular health education, examination, and follow-up.

Abstract

With the development of widespread Internet access, online game playing has become a popular event. As a result, more attention is being paid to the potentially negative physical and psychological effects on prolonged computer worker or online game player. To date, related physical problems that have been identified include fatigue, physical pain, insomnia, epileptic seizures, and even sudden death. Therefore, midterm break may be necessary for an online game player. This study tries to differentiate the physiological effects of two groups, with and without a midterm break, during a prolonged online game playing. Our experimental results showed that sympathetic system is overwhelming the parasympathetic nervous system significantly in group B without break, while it remains unchanged in group A. Due to the fight or flight response of the sympathetic system, participants with midterm break wanted to play more after event. Participants without break did not feel stressed after a continuous two hours' online game playing. These interesting findings may need further investigation in the future.

Applying Usability Test to Find the Interface Design Principle of HRV Device for Senior Users

Hsin-Chang Lo, I-Jen Sung, Yu-Ting Lin

Abstract

Home use medical device industry prospers due to the ageing society. In both physiological and psychological domain, home use medical devices have received much attention in recent years. Seniors usually feel depressed or anxious because of losing health and living abilities. They can use the heart rate variability (HRV) device in analyzing their emotional response, however the interface of commercial HRV devices are not easy for them to operate. Therefore, the usability test of these devices was introduced for the senior users. Five senior user were recruited to conduct usability test of the two commercial HRV devices: ANSWatch (Taiwan Scientific Corp.) and CheckMyHeart Handheld HRV (DailyCare BioMedical Inc.) follow the typical operation task. Then the in-depth interview were conducted to find operational failure factors. All of senior users indicated that the serious failure factors are: “unable to understand English instructions” and “unable to determine the meaning of illustration”. Four of them indicated that the minor ones are: “no appropriate guide”; “text is too small”; and “layout is not appropriate”. Three of them indicated that “illustration surface reflection” is another problem. Therefore, we suggests that the home use HRV device interface design should consider principles such as (1) the language and icon properties, (2) step guides and text properties, (3) consistency of interface configuration, (4) color scheme to improve the operational satisfaction for the senior users.

Abstract

Workplace stress-related illness is a serious issue, and consequently many stress reduction methods have been investigated. Aromatherapy is especially for populations that work under high stress. Elementary school teachers are a high-stress working population in Taiwan. In this study, fifty-four elementary school teachers were recruited to evaluate aromatherapy performance on stress reduction. Bergamot essential oil was used for aromatherapy spray for 10 minutes. Blood pressure and autonomic nervous system parameters were recorded 5 minutes before and after the application of the aroma spray. Results showed that there were significant decreases in blood pressure, heart rate, LF power percentage, and LF/HF while there were increases in heart rate variability and HF power percentage ( ) after application of the aromatherapy spray. Further analysis was investigated by dividing subjects into three background variables (position variables, age variables, gender variables) and anxiety degree groups. All parameters were significantly different for most subgroups, except for the substitute teachers and the light-anxiety group. Parasympathetic nervous system activation was measured after aromatherapy in this study. It encouraged further study for other stress working population by aromatherapy.

2.2. Experimental Procedures

Aromatherapy was conducted once a week. Physiological recordings were taken during the second week in the school’s health center. An Ultrasonic Ionizer Aromatherapy Diffuser was used for aroma evaporation (type YHL668/I, ultrasound frequency 2.5 MHz, Nature Creart Co. Ltd, made in Taiwan). 100% pure bergamot essential oil was used and diluted to 2%. Physiological parameters were recorded by an ANSWatch monitor (TS-0411 type, Taiwan Scientific Ltd., which has been approved by ISO 13485, and EU CE Mark). Each session was recorded for seven minutes. Average blood pressure and HRV parameters were shown on the panel of ANSWatch monitor. Detailed experimental procedures were as follows. IRB was approved by Asia University Medical Research Ethics committee.

Abstract

The purpose of this study was to examine the physiological effects of computer worker when surfing the web. Twenty subjects are measured with physiological indices four times in the morning and afternoon. The results showed that higher level of Internet addiction is not as expected different with the lower level of Internet addiction. After surfing the web, there are significant differences in subjects' HR in the morning and afternoon. LF is significantly higher, as this time people are more spiritual and concentration in the morning. HF is higher in the afternoon, so people feel more relax or fatigue.
