Studying today's data on health trends can give us a glimpse into what the future might hold for the nursing profession.
Late gadolinium enhancement (LGE) imaging is well validated for the diagnosis and quantification of myocardial infarction (MI). 2D LGE imaging involves multiple breath-holds for acquisition of short-axis slices to cover the left ventricle (LV). 3D LGE methods cover the LV in a single breath-hold; however, breath-hold duration is typically long with images susceptible to motion artifacts.
This study compared the visual inspection performance of airport security officers (screeners) when screening hold baggage with state-of-the-art 3D versus older 2D imaging.
General anesthesia (GA) or sedation has been used to obtain good-quality motion-free breath-hold chest CT scans in young children; however pulmonary atelectasis is a common and problematic accompaniment that can confound diagnostic utility. Dual-source multidetector CT permits ultrafast high-pitch sub-second examinations, minimizing motion artifact and potentially eliminating the need for a breath-hold.
Acute cholecystitis is defined as gallbladder inflammation caused by obstruction of the cystic duct. The pro-inflammatory cytokine, high mobility group box-1 (HMGB1), has been found to hold critical roles in the pathogenesis of several different inflammatory diseases. This study aimed to determine the relationship between HMGB1 and acute cholecystitis, and examine the potential for this cytokine as a biomarker for clinical diagnosis.
The purpose of this study is to determine the effect of different reader and patient parameters on the degree of agreement and the rate of misclassification of vesicoureteric reflux grading on last-image-hold frames in relation to spot-exposed frames from voiding cystourethrography (VCUG) as well as to determine the nature of reflux misclassification on last-image-hold frames.
The performance of elite breath hold divers (BHD) includes static breath hold for more than 11 minutes, swimming as far as 300 m, or going below 250 m in depth, all on a single breath of air. Diving mammals are adapted to sustain oxidative metabolism in hypoxic conditions through several metabolic adaptations, including improved capacity for oxygen transport and mitochondrial oxidative phosphorylation in skeletal muscle. It was hypothesized that similar adaptations characterized human BHD. Hence, the purpos...
To develop and validate a data processing technique that allows phase-contrast MRI-based 4D flow imaging of the aortic valve in a single breath-hold.
To synthesize evidence on the effects of hold-relax and contract-relax stretching (HR and CR) on hamstrings flexibility compared with no intervention and other stretching techniques.
The extent to which ectomycorrhizal fungi (ECM) enable plants to access organic nitrogen (N) bound in soil organic matter (SOM) and transfer this growth-limiting nutrient to their plant host, has important implications for our understanding of plant-fungal interactions and the cycling and storage of carbon (C) and N in terrestrial ecosystems. Empirical evidence currently supports a range of perspectives, suggesting that ECM vary in their ability to provide their host with N bound in SOM, and that this capac...
Incidence of transient interruption of contrast (TIC) - A retrospective single-centre analysis in CT pulmonary angiography exams acquired during inspiratory breath-hold with the breathing command: "Please inspire gently!"
To assess the occurrence of transient interruption of contrast (TIC) phenomenon in pulmonary computed tomography angiography (CTPA) exams performed in inspiratory breath-hold after patients were told to inspire gently.
We investigate various group-size distributions occurring in a situation where each group's resource is exposed to appropriation by other groups. The amount of appropriation depends on the size difference between groups. Our work focuses on the cases where the entire community isolates a small group or even an individual to maximize its gain. While people's basic motivation to form a group can be understood based on the group-size effect on multiplying a collective asset, sensitive factors that induce a asy...
A liquid-gas two-phase computational fluid dynamics (CFD) model was developed to simulate flow field and gas hold-up in a pilot-scale oxidation ditch (OD). The volume of fluid (VOF) model and the mass flow inlet boundary condition for gas injection were introduced in this model. The simulated values of the flow velocities and the gas hold-up were verified by experimental measurements in the pilot-scale OD. The results showed that the gas hold-up at test-site 3, immediately downstream of the surface aerator,...
The aim of this study was to investigate the suppression of inflammation and enhancement of osteogenesis using chitosan-coated calcium hydroxide-loaded microcapsules (CS-EC@Ca microcapsules) in vivo. Circular defects were created in the mandibular bones of rabbits and filled with Ca(OH) , Bio-oss, or CS-EC@Ca microcapsules, and rabbits without drug implantation served as the controls. Lipopolysaccharides were injected in situ daily in all groups for 7 days. Mandibular bones were investigated at 4 and 12 wee...
Aim of the present analysis was to evaluate the movement and dose variability of the different lymph node levels of node-positive breast cancer patients during adjuvant radiotherapy (RT) with regional nodal irradiation (RNI) in deep-inspiration breath hold (DIBH).
Evidence that Deep Inspiration Breath Hold (DIBH) can reduce cardiac dose during left-sided breast radiation therapy (RT) has led to widespread uptake of this technology. There is a paucity of published information documenting the impact of this technique on the patient's treatment experience. The aim of this study was to develop a tool to assess the patient's experience with the introduction of DIBH using the Elekta Active Breathing Coordinator (ABC) in a single institution.
In our preliminary experiment, we divided patients into 3 groups, 10 patients in each group. Group A received standard medicine treatment (SMT) only. Group B was treated with allogeneic bone marrow-derived MSCs (BM-MSCs) every week for 4 weeks, at a dosage of 1x10 per Kg. For Group C the dosage of BM-MSCs was 10x10 per Kg. No significant difference was found in the levels of liver functions and 24 week survival rate between Group B and Group C (data not published). This may be related with the peripheral ve...
Around 2008, endoscopists David Carr-Locke and Petros Benias began to notice an unfamiliar pattern in the bile duct during endomicroscopy, which didn't look like anything they knew from pathology. Their confusion as to what it was persisted, so they brought their observations to their colleague, pathologist Neil Theise. Eventually, a larger group of researchers worked to figure out what exactly they were seeing in the bile duct samples. Their ultimate conclusion was that the structure is part of a network o...
Functional electrical stimulation (FES) is a promising solution for restoring functional motion to individuals with paralysis, but the potential for achieving any desired full-arm reaching motion has not been realized. We present a combined feedforward-feedback controller capable of automatically calculating and applying the necessary muscle stimulations to hold the wrist of an individual with high tetraplegia in a desired static position. We used the controller to hold a complete arm configuration to maint...
The 2017 GOLD ABCD classification shifts patients from groups C-D to A-B. Group A was the most widely distributed group in several studies. It would be useful to understand the characteristics for group A patients, but little has been reported concerning these issues.
Fresh peripheral blood (PB) samples from 432 outpatients with stable chronic obstructive pulmonary disease (COPD) were examined. Patients were classified into Group A (large SRA cells were undetected) and Group B (large SRA cells were detected) and followed-up for 1 year. Patients were further subdivided according to Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage. Cox proportional hazard model had shown that Gold, Group, home oxygen therapy (HOT), and treatment were significant predicto...
This retrospective study investigated and compared the incidence of congenital foetal anomalies after letrozole versus clomiphene citrate (CC) administration for infertility treatment. Data from 142 newborns were included: letrozole group, n = 83; CC group, n = 61. Congenital anomalies were found in 7.2% (6/83) patients in the letrozole group and 18.0% (11/61) patients in the CC group, with no significant between-group difference (p = .066). Major congenital anomaly rate was 2.4% (2/83) in the l...
