Application of wireless analgesic system in pain management after thoracoscopic lung resection: A retrospective cohort study with large sample / 中国胸心血管外科临床杂志

@#Objective     To investigate the effect of intravenous analgesia with a wireless or traditional analgesia pump system in thoracoscopic lung resection. Methods     Patients who used the patient-controlled intravenous analgesia after thoracoscopic lung resection between June 2016 and June 2021 were enrolled in the study. They were allocated into a wireless pump group (a ZigBee-based wireless analgesia pump system collecting data automatically) and a traditional analgesia pump group. Perioperative analgesia management followed the routine standard operation protocol of Shanghai Chest Hospital. The patients’ numeric rating scale (NRS) for pain and postoperative nausea and vomiting (PONV) scores were collected for analysis from the Anesthesia Information Record System. The incidence of postoperative analgesia insufficiency (defined as NRS≥4 points) within 48 h, the incidence of PONV within 24 h, and the 48 h completion rate of analgesia pump infusion were compared. Results    A total of 59 431 patients were collected, including 24 855 males and 34 576 females, 17 209 patients in the wireless pump group, and 42 222 patients in the traditional analgesia pump group. The incidence of analgesia insufficiency within 48 h after operation (3.75% vs. 4.98%, P=0.007), the incidence of PONV within 24 h after operation (13.60% vs. 16.70%, P=0.030) in the wireless pump group were lower than those in the traditional analgesia pump group. The 48 h completion rate of analgesia pump infusion in the wireless pump group was higher than that in the traditional analgesia pump group (83.40% vs. 71.90%, P<0.001). The wireless pump group could monitor the pressing times and use of the analgesia pump, while the traditional analgesia pump group could not record the relevant data. Conclusion    Compared with the traditional analgesia pump, the wireless analgesia management system may be convenient for timely, accurate and individualized management, and has good analgesic effect and low incidence of adverse reactions, and may be more suitable for perioperative analgesia management.

A SIMPLE GIBBS SAMPLER FOR THE STATE ESTIMATION IN WIRELESS COMMUNICATIONS

In the recent years, wireless communications are extremely useful in many disciplines including health monitoring, environment monitoring, signal processing etc. State estimation and prediction are quite challenging tasks in wireless communications. Traditionally, in the literature, dynamic state-space models have been used for the state estimation and predic- tion purpose. The estimation method is based on Kalman-Filter which is computationally demanding. In this work, we consider computationally simpler Gibbs sampler algorithm for the state estimation. We consider three different cases, (i) continuous state values, (ii) binary (0/1) state values, and (iii) categorical state values with more than two categories. We consider a simple linear model for the prediction purpose, and the underlying regression coefficients are estimated by Gibbs sampler. We compute the misclassification proportions for assessing the practical usefulness of our estimation approach. Areal dataset where 200 wireless sensor nodes are used for measuring the temperature of a chamber is analysed in this work

ABSTRACT Purpose To identify relationships between Remote Microphone System (RMS) use in the classroom and the schools' and teachers' characteristics. Methods We analyzed 120 subjects aged 5 to 17 years with hearing loss who had received an RMS from a health service accredited by the Unified Health System (SUS). The teachers of RMS users were the other subjects in the study. We analyzed the patients' medical records and interviewed their parents/guardians at the follow-up visit to verify issues related to the RMS and its use at school. We contacted the schools over the phone and visited some of them. Results Of the students, 54% used the device at school; 22% involuntarily did not use it; and 24% voluntarily did not use it. The Speech Intelligibility Index pattern of those who used the RMS was similar to those who involuntarily did not use it. There was a significant difference between the type of school and educational level - 86% of regular school students and elementary school students tend to use the device more often (62%). Conclusion Most subjects use the RMS at school. The students' educational level also interfered with the adherence to RMS use, as elementary school students had a higher adherence. The data suggest that the coordination between health services and schools favors RMS use. However, when the parents mediate this relationship, other factors interfere with the systematic RMS use in the school routine.

Método: Se analizaron 175 sujetos de entre 5 y 17 años que recibieron el SMR en un servicio de salud auditiva entre los años 2017 y 2018. Los padres y maestros de los usuarios también fueron sujetos del estudio. Se ha comprobado el funcionamiento del SMR y la clasificación relativa a su uso. Resultado: Los individuos que "usan" más el SMR están en la escuela primaria, y los que "no usan voluntariamente" están en la secundaria. Considerando el tipo de escuela, la mayoría de los que "no usan voluntariamente" el SMR está en una escuela o sala para sordos con uso de libras y/o tiene un intérprete en la sala de la escuela regular. Conclusión: Hubo una asociación entre el uso del SMR y el tipo de la escuela. Se recomienda que el tipo de escuela sea un criterio para indicar el dispositivo. El nivel educativo, también fue una variable determinante en el uso del dispositivo en la escuela.

Effects of low-power wireless power transfer system on memory behavior and part of physiological properties of mice / 生物医学工程学杂志

Wireless power transfer (WPT) is a new power transmission way, which can be widely used in electric vehicles and other fields. Its electromagnetic environment must be analyzed to ensure safe application. A low-power wireless power transfer system experimental platform was built, with 25 W receiving power and 47 kHz resonant frequency, which was used to carry out animal experiments. Treatment mice were exposed to environment of wireless power transfer system for 5 h a day and 6 days as one cycle. At the end of every cycle, learning memory behavior of mice were detected in T-shaped maze. The exposure experiment lasted for 12 weeks. Finally, immune parameters, sex hormones and part of organ physiological structure were detected. The results are as follows: as exposure time increased, memory behavior of mice did not change obviously with no statistical difference in sex hormone either ( > 0.05), the concentration of immune factors including tumor necrosis factor-α (TNF-α), interleukin 6 (IL-6) and interleukin-1 beta (IL-1β) significantly increased ( < 0.05), and the structure of some organs showed some changes. The experimental results show that the environment of the wireless power transfer system has no effect on the memory behavior of mice, and has some effect on physiological properties of mice.

Wireless amplified nuclear MR detector in high-resolution MR imaging of temporomandibular joint / 中国医学影像技术

Objective: To observe the application value of wireless amplified nuclear MR detector (WAND) in high-resolution MR imaging of temporomandibular joint (TMJ). Methods: Totally 16 healthy youths underwent bilateral TMJ MR scanning using head-neck combined coil and WAND coupled head-neck combined coil respectively. The anterior band, intermediate band, posterior band, anterior attachment, posterior attachment and double plate area, articular cavity, condylar bone of TMJ on the images obtained with 2 methods were observed and subjectively evaluated. The image quality of the articular disc, whose signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were evaluated for objective evaluation. The subjective scoring and objective evaluation were compared between 2 groups. Results: A total of 15 subjects were included. Compared with images obtained with head-neck combined coil, images obtained with WAND coupled head-neck combined coil had obvious advantages in displaying the disc of anterior, middle and posterior, anterior attachment, posterior attachment, double-plate area and joint cavity and condyle bone of TMJ (all P<0.05), also had significantly higher CNR and SNR of the articular disc and posterior tissue of TMJ (both P<0.05). Conclusion: WAND coupled head-neck combined coil can improve MR image quality of TMJ.

0.9 between all observers). Receiver operating characteristic curve analysis showed that the predictive power for CAD was improved when max-CIMT and plaque information (plaque≥2) was added [area under the curve (AUC): 0.838] to the traditional clinical CV risk factors (AUC: 0.769). The cutoff values for CAD prediction with the standard device and the WHUS device were 1.05 mm (AUC: 0.807, sensitivity: 0.78, specificity: 0.53) and 1.10 mm (AUC: 0.725, sensitivity: 0.98, specificity: 0.27), respectively.CONCLUSION: max-CIMT measured by a WHUS device showed excellent agreement and repeatability, compared with standard ultrasound. Combined max-CIMT and plaque information added predictive power to the traditional clinical CV risk factors in detecting high-risk CAD patients.
