Ankle torque is the most frequent injury mechanism encountered in traumatology. It usually develops as an ankle sprain, and often produces an ankle fracture. Signs and symptoms are very unspecific on the differential diagnosis, and conventional radiographs must be obtained to confirm it. This study compares ultrasound and standard X-ray images values found in ankle sprain-related fracture diagnoses. A 3-month prospective study was carried out on 52 patients with ankle torque. First, an ultrasound diagnosis was made by the first researcher at their arrival to the emergency department, usually consisting of a longitudinal section of the fibula, tibia, and V metatarsal...

The use of zero-waste processes to integrate food-waste valorisation into the circular economy equation is currently one of the hottest topics in sustainability research. This goal is still far from being fully achieved despite the release of a number of patents and papers that deal with the topic. The present work aims to valorise cocoa shells, one of the main by-product of the roasting process, in order to enhance the effective extraction of high added value compounds by means of green protocols. The high potential added value of the residual waste has been demonstrated via a direct analytical comparison of extracts and bean composition...

Ultrasound imaging is a widespread method used to detect organ anomalies and tumors in human and animal tissues. The method is non-invasive, harmless, and painless, and the application is easy, fast, and can be done anywhere, even with mobile devices. During pregnancy, ultrasound imaging is standardly used to closely monitor fetal development. The technique is important to assess intrauterine growth restriction (IUGR), a pregnancy complication with short- and long-term health consequences for both the mother and fetus...

An ultra-fast non-conventional waste management protocol was being designed and applied to recycle and reuse industrial coal fly ash (CFA) waste to generate highly pure nanozeolite X. Both microwave heating-assisted hydrothermal treatment method and ultrasonic waves-assisted hydrothermal method have been successfully used for the fast valorization of power plant CFA waste, and the results were compared with conversional valorization method for CFA conversion to zeolite. While conventional methods like hydrothermal treatment using sodium hydroxide took up to 4 days in valorization of the solid CFA waste into a useful zeolitic X material; the non-conventional methods using microwave irradiation of frequency 2...

Consumption of a representative fast-food meal (FFMeal) acutely impairs peripheral conduit artery vascular function; however, the effect on cerebral vascular function remains unknown. This study tested the hypothesis that a FFMeal would impair cerebral vascular function as indexed by an attenuated increase in cerebral vascular conductance (CVCI) in the middle cerebral artery (MCA) during a hypercapnic challenge. Ten healthy men (age: 24 ± 3 years, BMI: 24.3 ± 3.8 kg/m2 ) were studied under two conditions; a standardized FFMeal (990 kcals, 50% fat, 36% carbohydrate, 14% protein, and 2120 mg sodium) and a fasting control condition...

MRI of the breast is the most sensitive test for breast cancer detection and outperforms conventional imaging with mammography, digital breast tomosynthesis, or ultrasound. However, the long scan time and relatively high costs limit its widespread use. Hence, it is currently only routinely implemented in the screening of women at an increased risk of breast cancer. To overcome these limitations, abbreviated dynamic contrast-enhanced (DCE)-MRI protocols have been introduced that substantially shorten image acquisition and interpretation time while maintaining a high diagnostic accuracy...

NEW FINDINGS: What is the central question of this study? Does folic acid supplementation alleviate thermoregulatory and cardiovascular strain of older adults during exposure to extreme heat and humidity? What is the main finding and its importance? Folic acid supplementation for 6 weeks did not affect whole-limb blood flow/vasodilatation, core and skin temperatures, heart rate, blood pressure and cardiac output. Thus, 6 weeks of folic acid supplementation does not alleviate thermoregulatory or cardiovascular strain of healthy older adults exposed to extreme heat and humidity...

BACKGROUND: Pulmonary aspiration of gastric contents is associated with significant perioperative morbidity and mortality. Previous studies have investigated the validity, reliability, and possible clinical impact of gastric ultrasound for the assessment of gastric content at the bedside. In the present study, we examined the accuracy (evaluated as sensitivity, specificity, and likelihood ratios) of point-of-care gastric ultrasound to detect a "full stomach" in a simulated scenario of clinical equipoise...

We report a renal laceration identified on a point-of-care ultrasound (POCUS) performed in the emergency department on a 58-year-old female presenting after blunt trauma. Emergency workup demonstrated a right flank abrasion with tenderness to palpation, hematuria, and decreasing hematocrit. A Focused Assessment with Sonography in Trauma (FAST) exam, performed as part of the intake trauma protocol, identified positive intraperitoneal fluid in the right upper quadrant. A computed tomography (CT) scan established a diagnosis of isolated right renal hematoma arising from a Grade IV laceration, with no collecting duct involvement...

Upcoming phased-array 2-D sensors will soon enable fast high-definition 3-D ultrasound imaging. Currently, the communication of raw radio-frequency (RF) channel data from the probe to the computer for digital beamforming is a bottleneck. For reducing the amount of transferred data samples, this paper investigates the design of an adapted sparse sampling technique for image reconstruction inspired by the compressed sensing framework. Echo responses from isolated points are generated using a physically based simulation of ultrasound wave propagation through tissues...

BACKGROUND: Point-of-care ultrasonography plays an increasingly important role in the initial resuscitation of critically ill patients but acquisition of the skill is associated with long learning curves. The skills required to perform ultrasound examinations can be practiced in a simulated setting before being performed on actual patients. The aim of this study was to investigate the learning curves for novices training the FAST protocol on a virtual-reality simulator. METHODS: Ultrasound novices (N = 25) were instructed to complete a FAST training program on a virtual-reality ultrasound simulator...

The developmental goal of 3D ultrasound imaging (3DUS) is to engineer a modality to perform 3D morphological ultrasound analysis of human muscles. 3DUS images are constructed from calibrated freehand 2D B-mode ultrasound images, which are positioned into a voxel array. Ultrasound (US) imaging allows quantification of muscle size, fascicle length, and angle of pennation. These morphological variables are important determinants of muscle force and length range of force exertion. The presented protocol describes an approach to determine volume and fascicle length of m...
