Evaluation of the Accuracy of a New Cuffless Magnetoplethysmography Blood Pressure Monitor in Hypertensive Patients.

Objective: There is a growing demand for cuffless blood pressure (BP) measurement as an easy alternative to cuff-occlusion-based BP measurement. We assessed the accuracy of a new cuffless, watch-style BP monitor with a magnetoplethysmography (MPG) sensor compared to two standard auscultatory and oscillatory BP monitors.

Subjects And Methods: A total of 34 patients with uncontrolled hypertension (systolic BP ≥150 mm Hg or diastolic BP ≥95 mm Hg) were enrolled in the study.

Prolonged stimulation with low-intensity ultrasound induces delayed increases in spontaneous hippocampal culture spiking activity.

Ultrasound is a promising neural stimulation modality, but an incomplete understanding of its range and mechanism of effect limits its therapeutic application. We investigated the modulation of spontaneous hippocampal spike activity by ultrasound at a lower acoustic intensity and longer time scale than has been previously attempted, hypothesizing that spiking would change conditionally upon the availability of glutamate receptors. Using a 60-channel multielectrode array (MEA), we measured spontaneous spiking across organotypic rat hippocampal slice cultures (N = 28) for 3 min each before, during, and after stimulation with low-intensity unfocused pulsed or sham ultrasound (spatial-peak pulse average intensity 780 μW/cm ) preperfused with artificial cerebrospinal fluid, 300 μM kynurenic acid (KA), or 0.

Design of real-time encryption module for secure data protection of wearable healthcare devices.

Wearable devices for biomedical instrumentation could generate the medical data and transmit to a repository on cloud service through wireless networks. In this process, the private medical data will be disclosed by man in the middle attack. Thus, the archived data for healthcare services would be protected by non-standardized security policy by healthcare service provider (HSP) because HIPAA only defines the security rules.

The association between pulse wave velocity and metabolic syndrome in Korean.

The objective of this study was to compare aortic (the common carotid to femoral artery) PWV, arm (the brachial to radial artery) PWV, and leg (the femoral to dorsalis pedis artery) PWV in people with or without component of the metabolic syndrome. We analyzed 3345 Korean subjects (1907 men, age 44.6 ± 8.

Integrated Solution for Physical Activity Monitoring Based on Mobile Phone and PC.

Objectives: This study is part of the ongoing development of treatment methods for metabolic syndrome (MS) project, which involves monitoring daily physical activity. In this study, we have focused on detecting walking activity from subjects which includes many other physical activities such as standing, sitting, lying, walking, running, and falling. Specially, we implemented an integrated solution for various physical activities monitoring using a mobile phone and PC.

A pilot study of the Tele-Airway Management System in a hospital emergency department.

We developed a telemedicine system for remote guidance of emergency airway management called the Tele-Airway Management System (TAMS). In a pilot study we examined the usefulness of the TAMS for intubations of actual patients in a hospital emergency department. Twenty-five patients were allocated randomly either to a TAMS group or to an on-scene directed (OSD) group.

Performance evaluation of the electrode configuration in bioelectrical impedance analysis for visceral fat measurement.

Excessive amount of visceral fat is considered as a crucial indicator for the metabolic syndrome (MS). Visceral fat area (VFA) at the umbilicus level measured by CT is adopted as the gold standard, but it has many limitations. Recently, Application of bioelectrical impedance analysis (BIA) for measuring VFA is widely used.

Portable emergency telemedicine system over wireless broadband and 3G networks.

The telemedicine system aims at monitoring patients remotely without limit in time and space. However the existing telemedicine systems exchange medical information simply in a specified location. Due to increasing speed in processing data and expanding bandwidth of wireless networks, it is possible to perform telemedicine services on personal digital assistants (PDA).

A portable dental image viewer using a mobile network to provide a tele-dental service.

We tested three imaging devices for suitability in emergency dental situations for telemedicine. The three devices were a special-purpose oral camera, a digital single lens reflex (DSLR) camera, and the built-in camera of a mobile phone. A total of 20 subjects volunteered to take part in the study.

Real-time Ambulance Location Monitoring using GPS and Maps Open API.

The term 'Open API' has been recently in use by recent trends in social media and web 2.0. It is currently a heavily sought after solution to interconnect Web sites in a more fluid user-friendly manner.

Design of RFID based the Patient Management and Tracking System in hospital.

The patient location information in managing for patient workflow will be worked efficiently within the hospital. We designed the Patient Management and Tracking System (PMTS) based on RFID with RSSI(Received Signal Strength Indication) method. This system is able to track the movement of patient in hospital, and manage the waiting-list of patients at a medical office.
