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...

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...

Serial femtosecond crystallography (SFX) using the ultrashort X-ray pulses from a X-ray free-electron laser (XFEL) provides a new way of collecting structural data at room temperature that allows for following the reaction in real time after initiation. XFEL experiments are conducted in a shot-by-shot mode as the sample is destroyed and replenished after each X-ray pulse, and therefore, monitoring and controlling the data quality by using in situ diagnostic tools is critical. To study metalloenzymes, we developed the use of simultaneous collection of X-ray diffraction of crystals along with X-ray emission spectroscopy (XES) data that is used as a diagnostic tool for crystallography, by monitoring the chemical state of the metal catalytic center...

BACKGROUND: Previous studies have revealed that triglyceride to high-density lipoprotein cholesterol (HDL-C) ratio (henceforth TG/HDL-C) is one of major risk factors of cardiovascular diseases, insulin resistance and metabolism syndrome. However, there are fewer scientific dissertations about the correlation between TG/HDL-C and bapWV. This study was undertaken to investigate the relationship between Triglyceride (TG) to high-density lipoprotein cholesterol (HDL-C) ratio and brachial-ankle pulse wave velocity (baPWV) in Japanese...

BACKGROUND: Atrial fibrillation (AF) is an important and modifiable risk factor for stroke. Earlier identification may reduce stroke-related morbidity and mortality. Trial evidence shows that opportunistic pulse regularity checks in individuals aged ≥65 years increases detection of AF. However, this is not currently recommended by the National Screening Programme or implemented by most clinical commissioning groups (CCGs). AIM: To evaluate the impact of a systematic programme to promote pulse regularity checks, the programme's uptake in general practice, and the prevalence of AF...

BACKGROUND: Peripheral arterial disease (PAD) is a common circulatory problem in which narrowed arteries reduce blood flow to extremities, usually legs. It does not receive enough blood flow to keep up with demand. This causes symptoms, most notably leg pain while walking which is known as claudication. It is a common manifestation of type-2 Diabetes, but the relationship between other vascular diseases and lower limb peripheral arterial disease (LLPAD) has been poorly understood and investigated...

Forward pump pulses with nanosecond duration are able to generate an acoustic wave via electrostriction through a few centimeters of bulk silica. Part of the incident energy is then scattered back on this sound wave, creating a backward Stokes pulse. This phenomenon known as stimulated Brillouin scattering (SBS) might induce first energy-loss, variable change of the temporal waveform depending on the location in the spatial profile making accurate metrology impossible, and moreover it might also initiate front surface damage making the optics unusable...
