BACKGROUND: Repeated mild traumatic brain injury (mTBI) has been associated with increased risk of degenerative neurological disorders. While the effects of mTBI and repeated injury are known, studies have only recently started examining repeated subconcussive impacts, impacts that do not result in a clinically diagnosed mTBI. In these studies, repeated subconcussive impacts have been connected to cognitive performance and brain imaging changes. OBJECTIVE: Recent research suggests that performance on a visuomotor tracking (VMT) task may help improve the identification of mTBI...

BACKGROUND: Local hospitals must deal with large numbers of patients during mass casualty incidents, and the wireless sensor networks (WSNs) can help in these situations by monitoring vital signs. Conventional ZigBee nodes can obtain the ID of a device by assigning a unique 16-bit short address or by burning firmware into an IC. These methods tend to complicate node management and lack portability. OBJECTIVE: The study developed a node management mechanism to deal with a large number of patients in real-time, through the wireless monitoring of physiological signals...

BACKGROUND: Wearable healthcare systems require measurements from electrocardiograms (ECGs) and photoplethysmograms (PPGs), and the blood pressure of the user. The pulse transit time (PTT) can be calculated by measuring the ECG and PPG simultaneously. Continuous-time blood pressure without using an air cuff can be estimated by using the PTT. OBJECTIVE: This paper presents a biosignal acquisition integrated circuit (IC) that can simultaneously measure the ECG and PPG for wearable healthcare applications...

BACKGROUND: Due to the incremental increase of clinical interest in the development of software that allows the 3-dimensional (3D) reconstruction and the functional assessment of the coronary vasculature, several software packages have been developed and are available today. OBJECTIVE: Taking this into consideration, we have developed an innovative suite of software modules that perform 3D reconstruction of coronary arterial segments using different coronary imaging modalities such as IntraVascular UltraSound (IVUS) and invasive coronary angiography images (ICA), Optical Coherence Tomography (OCT) and ICA images, or plain ICA images and can safely and accurately assess the hemodynamic status of the artery of interest...

BACKGROUND: Survival rates of out-of-hospital cardiac arrest remain poor. Bystander cardiopulmonary resuscitation (CPR) is crucial for survival and feedback devices could improve its quality. OBJECTIVE: We investigated quality of chest compression when using the Cardio First AngelTM (CFA) feedback device compared to standard basic life support (BLS). The analysis focused on laymen. METHODS: Laymen without (n= 43) and with (n= 96) explanation of the device, medical students (n= 128) and medical staff (n= 27) performed 60 seconds of standard versus assisted chest compression using the CFA on a resuscitation manikin...

A needle-free vaccine/drug injector that works by virtue of the impulse of a moving shock wave is presented in this communication. The device can deliver controlled micro-volumes of liquid vaccines into skin and soft tissue targets in human with minimal invasion. The operation of the injector was investigated by delivering a dyed liquid into human skin samples and soft tissue models. The depth of penetration of the liquid was examined by histology of the targeted human skin samples. The delivery mechanics and the depth of penetration were analyzed theoretically with an elastic model for the skin and a viscoelastic model for the soft tissue targets, and a good agreement with experiments was observed...

Qingying Zhao, Min Li, Jun Luo
BACKGROUND: In nanomachine applications towards targeted drug delivery, drug molecules released by nanomachines propagate and chemically react with tumor cells in aqueous environment. If the nanomachines release drug molecules faster than the tumor cells react, it will result in loss and waste of drug molecules. It is a potential issue associated with the relationship among reaction rate, release rate and efficiency. OBJECTIVE: This paper aims to investigate the relationship among reaction rate, release rate and efficiency based on two drug reception models...

In psychiatry, mindfulness based intervention has been increasingly popular as a means of psychosocial intervention over the last decade. With the alvanche of technological advances, there has been a myriad of mindfulness based applications. Recent reviews have highlighted how these applications are lacking in functionalities and without demonstrated efficacy. Other reviews have emphasized that there is a need to take into consideration the design of an application, due to placebo effects. It is the aim of this technical note to illustrate how the 5-Minutes Mindfulness application, which is an application designed to provide mindfulness exercises to relieve distress and suffering amongst palliative patients, have been conceptualized...

BACKGROUND: Information and communications technology has attracted attention as a useful way of sharing care records in community-based care. Such information sharing systems, however, imposed the burden of inputting the same records into different information systems due to a lack of interoperability of the systems. OBJECTIVES: The purpose of this study was to develop a gateway that links information systems and to investigate the functionality and usability of the gateway through an empirical study...

BACKGROUND: Measuring portal venous pressure is necessary to examine, diagnose, and treat portal hypertension, but current methods are invasive. OBJECTIVE: This study aimed to determine whether a noninvasive peripheral blood measurement could be used to estimate portal venous pressure by investigating correlations between certain physical parameter measurements in the peripheral blood with those obtained in portal blood samples. METHODS: A total of 128 peripheral and portal blood samples from patients (n= 128) were analyzed for blood rheology and routine blood parameters...
