BACKGROUND: Troponin I is better than other troponin isoforms for monitoring cardiocyte damage, and correlates with sepsis-related mortality. However, hemodynamic factors possibly interact with cardiac function to affect mortality in sepsis. Thus, this study used parameters from pulse-induced contour cardiac output (PiCCO) to investigate the possibility. METHODS: Patients with troponin I tests and sequential organ failure assessment score ≥2 were selected and divided into survivors and nonsurvivors groups and blood troponin I levels between them were compared...

OBJECTIVE: For health professionals, the absence of pulse checked by manual palpation is a primary indicator for initiating chest compressions in patients considered to have cardiopulmonary arrest (CA). However, using a pulse check to evaluate perfusion during CA may be associated with some risks of its own. Our objective was to compare the efficiency of cardiac ultrasonography (CUSG), Doppler ultrasonography (DUSG), and manual pulse palpation methods to check the pulse in CA patients...

INTRODUCTION: Point-of-care ultrasound (POCUS) has been suggested as a useful tool to predict survival and guide interventions in out-of-hospital cardiac arrest (OHCA). While POCUS has been deployed in prehospital settings, little data exists on prehospital use, particularly by personnel with limited ultrasound experience. We aimed to characterize the feasibility and barriers to prehospital POCUS during OHCA by EMS physicians in training. METHODS: We deployed the SonoSite iViz portable ultrasound device for use by EMS physicians for OHCA in an urban EMS system...

Previous studies provide evidence that Tai Chi (TC) can reduce the symptoms of sleep problems and be of benefit for the rehabilitation of substance abusers. In this study, we investigated if TC practice can improve sleep quality and mood of females who are dependent on amphetamine-type stimulant (ATS). Eighty subjects were randomly assigned to TC intervention and standard care (SC) for 6 months. We applied analysis of variance on repeated-measure with the year of drug dependence as the covariate to test the changes of the self-rated Pittsburg Sleep Quality Index (PSQI), Self-Rating Depression Scale (SDS), as well as fitness after 3 and 6 months...

For humans and for non-human primates heart rate is a reliable indicator of an individual's current physiological state, with applications ranging from health checks to experimental studies of cognitive and emotional state. In humans, changes in the optical properties of the skin tissue correlated with cardiac cycles (imaging photoplethysmogram, iPPG) allow non-contact estimation of heart rate by its proxy, pulse rate. Yet, there is no established simple and non-invasive technique for pulse rate measurements in awake and behaving animals...

We designed a photon-counting receiver system for long-distance underwater wireless laser communication at different code rate Reed-Solomon (RS) and low-density parity check (LDPC) codes. The symbol error rate (SER) performance of the LDPC and RS codes with different signal-to-noise ratios was analyzed. The effects of the background noise, pulse stretching, and frame synchronization were considered in our receiver system. A water tank experiment confirmed that the 1/2-code-rate RS (255,127) is an excellent coding strategy for communication distances in the range of 90-130 m in Jerlov II water...

BACKGROUND: Detection of undiagnosed or undertreated ("actionable") atrial fibrillation could increase the use of appropriate oral anticoagulant therapy and reduce the risk of stroke. We sought to compare newer screening technologies with a pulse-check for the detection of atrial fibrillation and to determine whether the detection of actionable atrial fibrillation increases the use of oral anticoagulant agents. METHODS: This prospective multicentre cohort study involved 22 primary care clinics...

Objectives: Paramedics and emergency medical technicians (EMTs) perform triage at disaster sites. There is a need for disaster triage training. Live simulation training is costly and difficult to deliver. Screen-based simulations may overcome these training barriers. We hypothesized that a screen-based simulation, 60 Seconds to Survival (60S), would be associated with in-game improvements in triage accuracy. Methods: This was a prospective cohort study of a screen-based simulation intervention, 60S...

Pulse pressure (PP) is a risk factor for cardiovascular diseases and is associated with increased afterload and myocardial oxygen demand. Brain natriuretic peptide (BNP) and heart-type fatty acid-binding protein (H-FABP) are known as biomarkers indicating ventricular wall stress and silent myocardial damage. However, the association between PP and ventricular wall stress and silent myocardial damage in the general population is unclear. The authors enrolled 3504 patients who participated in a community-based annual health check...

Mobile X-ray device is widely employed because it is useful for diagnosis in patients having mobility difficulties and in medical emergencies. As various devices for X-ray generation have continued to be developed, X-ray devices can now be used more safely and effectively. However, mobile X-ray devices generate relatively low X-ray doses due to the limitation of the power input. Therefore, the use of mobile X-ray devices is limited to thin parts of body. In this study, a new device was designed in order to increase the usefulness of mobile X-ray devices by offsetting the weaknesses of the existing mobile X-ray devices, rendering them useable independently...

Plasma Facing Components (PFC) temperature measurement is mandatory to ensure safe high power and long pulse tokamak operation. IR thermography systems which are widely used in magnetic fusions devices become challenged with the choice of tungsten as a PFC material in the ITER tokamak, mainly due to emissivity uncertainties and reflection issues in a hot environment. Embedded temperature measurements are foreseen to cross-check the IR thermography measurements. Fiber Bragg grating sensors are potentially of great interest for this application because they are immune to electromagnetic interference and allow the measurement of a large number of temperature spots on a single fiber...
