Prevalence, Characteristics, and Outcomes Associated with Acute Kidney Injury among Adult Patients with Severe Dengue in Mainland China

ABSTRACT. Acute kidney injury (AKI) can occur in adult patients with severe dengue (SD) and have serious clinical outcomes. This study aimed to determine the prevalence, characteristics, risk factors, and clinical outcomes of AKI in adult patients with SD; the correlation of dengue virus (DENV) serological and virological profiles with AKI; and the clinical features of patients with severe AKI who received renal replacement treatment (RRT). This multicenter study was conducted in Guangdong Province, China, between January 2013 and November 2019. A total of 242 patients were evaluated, of which 85 (35.1%) developed AKI and 32 (13.2%) developed severe AKI (stage 3). Patients with AKI had a higher fatality rate (22.4% versus 5.7%; P < 0.001) and longer length of hospital stay (median: 13 versus 9 days; P < 0.001). Independent risk factors for AKI were hypertension (odds ratio [OR]: 2.03; 95% CI: 1.10–3.76), use of nephrotoxic drugs (OR: 1.90; 95% CI: 1.00–3.60), respiratory distress (OR: 4.15; 95% CI: 1.787–9.632), high international normalized ratio (INR) levels (OR: 6.44; 95% CI: 1.89–21.95), and hematuria (OR: 2.12; 95% CI: 1.14–3.95). There was no significant association between DENV serological and virological profiles and the presence or absence of AKI. Among patients with severe AKI, those who received RRT had a longer length of hospital stay and similar fatality rate. Hence, adult patients with SD should be closely monitored for the development of AKI to enable timely and appropriate therapy.
Have Diagnostics, Therapies, and Vaccines Made the Difference in the Pandemic Evolution of COVID-19 in Comparison with “Spanish Flu”?

In 1918 many countries, but not Spain, were fighting World War I. Spanish press could report about the diffusion and severity of a new infection without censorship for the first-time, so that this pandemic is commonly defined as “Spanish flu”, even though Spain was not its place of origin. “Spanish flu” was one of the deadliest pandemics in history and has been frequently compared with the coronavirus disease (COVID)-19 pandemic. These pandemics share similarities, being both caused by highly variable and transmissible respiratory RNA viruses, and diversity, represented by diagnostics, therapies, and especially vaccines, which were made rapidly available for COVID-19, but not for “Spanish flu”. Most comparison studies have been carried out in the first period of COVID-19, when these resources were either not yet available or their use had not long started. Conversely, we wanted to analyze the role that the advanced diagnostics, anti-viral agents, including monoclonal antibodies, and innovative COVID-19 vaccines, may have had in the pandemic containment. Early diagnosis, therapies, and anti-COVID-19 vaccines have markedly reduced the pandemic severity and mortality, thus preventing the collapse of the public health services. However, their influence on the reduction of infections and re-infections, thus on the transition from pandemic to endemic condition, appears to be of minor relevance. The high viral variability of influenza and coronavirus may probably be contained by the development of universal vaccines, which are not easy to be obtained. The only effective weapon still remains the disease prevention, to be achieved with the reduction of promiscuity between the animal reservoirs of these zoonotic diseases and humans.
Transforming Bubble Wrap and Packaging Plastic Waste into Valuable Fuel Resources

This study aimed to investigate the potential of plastic waste, specifically bubble wrap and packaging plastic, as a fuel source through pyrolysis process. The samples were analyzed using FTIR and GC-MS. The results showed that both samples contained alkanes and alkenes, with hydrocarbon fractions like those found in gasoline, kero - sene, and diesel fuel. The pyrolysis process resulted in hydrocarbon fractions ranging from light to heavy fractions. The bubble wrap sample showed the highest percentage of hydrocarbon fraction in the kerosene range (C10–C13), with an area of 19.23%. In contrast, the packaging plastic sample showed the highest percentage of hydrocarbon fraction in the diesel range (C14–C20), with an area percentage of 19.67%. The calorific value of the pyrolysis products was also determined, with the bubble wrap sample having a higher value than that of gasoline, while the packaging plastic sample had a value close to that of kerosene. The results of this study suggest that plastic waste has the potential to be converted into fuel, which can contribute to sustainable development by reducing depen - dence on fossil fuels and reducing plastic waste. However, further refinement of the pyrolysis products is needed to meet commercial fuel standards.
Modeling the Atmospheric Ionization Rate During a Geomagnetic Reversal

The Matuyama‐Brunhes reversal of Earth's magnetic dipole field took place 0.78 Ma ago, and detailed temporally resolved paleomagnetic data are available for this period. A geomagnetic reversal is expected to impact the cosmic ray flux, which in turn affects atmospheric ionization rates. To assess the magnitude of this effect, three preexisting models are used in tandem to yield 3D time series of the atmospheric ionization rates for the entire globe during the reversal. Specifically the time variable paleomagnetic field data is input into a particle trajectory calculator to produce geomagnetic cutoff rigidity maps for the entire globe. This is combined with an empirical model of the local interstellar cosmic ray spectrum and ionization yield functions based on Monte Carlo atmospheric particle simulations to produce novel time variable 3D atmospheric ionization rates during the reversal. As the dipole field weakens, the atmospheric ionization increases at low latitudes. The increase is ca. 25% at the surface and up to a factor of 5 in the upper atmosphere. Globally, ionization rates increase around 13% at the surface and up to a factor of 2 in the upper atmosphere, whereas polar regions are largely unaffected. Finally, the change in ionization due to the solar 11‐year cycle is greatly affected by the reversal. The relative change in atmospheric ionization between solar‐minimum and solar‐maximum varies between 2 and two orders of magnitude.
Adapted digital domino game: Teaching multiplication to children

Developing and evaluating additional tools for teaching Mathematics, such as games, can contribute to improving student engagement and, consequently, their performance. This study evaluated the effects of an adapted digital domino game, based on the stimulus equivalence paradigm, developed for teaching relationships between numerals (A), sets of dots (B), and multiplication operations with numbers (C) and in a scale format (D). Five children with low performance in solving multiplication operations participated. Numeral naming skills, set naming skills, and multiplication operations were assessed in the Pretest. Then, ABBA, ACCA, and DCCD relationships were taught and BCCB, ADDA, and DBBD relationships were tested. Probes were performed throughout the study. Categorized behavior records assessed usability and engagement in the game. All participants learned the relationships taught and showed the emergence of the tested relationships, and an increase in the percentage of correct answers for the operations in the two formats and with unknowns in the three different positions.
Wideband Quasi-Spherical Lens Antenna Module With 2-D Switched Beams for 5G Millimeter-Wave IoT Applications

Millimeter-wave (mmWave) communication technologies offer abundant spectrum resources and higher data rates that present new opportunities to facilitate fifth-generation (5G) Internet of Things (IoT) systems. As IoT devices are randomly distributed in the environment, mmWave antennas with multiple switched directional beams are a better choice to reduce data collisions. In this context, a wideband multibeam antenna with a compact structure is presented for various mmWave IoT applications. First, a wideband dual-polarized magnetoelectric dipole (ME-dipole) antenna is developed as the excitation for the quasi-spherical lens. Next, by incorporating the lens with a group of the source antennas positioned at each edge of a hexagonal ground plane, six tilted beams with dual polarization are generated for pattern and polarization diversities. A prototype is constructed and measured, demonstrating a measured bandwidth from 27 to 37 GHz. Moreover, the maximum measured gain for each beam is around 18 dBi. Benefiting from the advantages of wideband operation and excellent radiation performance, the proposed mmWave-powered multibeam antenna can be mounted on the ceiling to communicate with multiple users and smart devices beneath it, offering a reliable and cost-effective solution for 5G IoT.
The h-extra conditional diagnosability of hypercubes under the PMC model and MM* model

ABSTRACT Diagnosis plays an important role in maintaining reliability of multiprocessor systems.

Then we extend their result under the MM model, and we have when , .
The Influence of Elevated CO2 Concentrations on the Growth of Various Microalgae Strains

The influence of elevated CO2 concentrations on the growth and viability of various microalgae strains was studied. Arthrospira platensis, Chlorella ellipsoidea, Chlorella vulgaris, Gloeotila pulchra, and Elliptochloris subsphaerica were tested. The cultivation of microalgae was carried out at constant CO2 concentrations (0.04, 3, 6, or 9%—sequentially from lower to higher concentrations), under constant (24 h·day−1) illumination with an intensity of 74.3 µmol quanta·m−2·s−1, and a constant temperature of 23.5 ± 0.5 °C. The optical density of the microalgae biomass, pH, and the chemical composition of the culture medium were measured. Microscopy (including the cytochemical microscopic method) was conducted to monitor the state of the microalgae. The highest biomass growth rate (0.37 g·L−1·day−1), among all experiments, was achieved for Chlorella vulgaris at CO2 = 3% and for Chlorella ellipsoidea at CO2 = 6 and 9%. The lowest growth rate (0.12 g·L−1·day−1) was achieved for Arthrospira platensis at CO2 = 3 and 9%. The microscopy results showed the absence or a minimum number of dead cells of the strains under selected conditions. The ability to maintain the viability of cultures up to significant concentrations of CO2 = 9% was due to adaptation (gradual increase in CO2 concentrations in the experiments).
Tensor Decomposition Analysis of Longitudinal EEG Signals Reveals Differential Oscillatory Dynamics in Eyes-Closed and Eyes-Open Motor Imagery BCI: A Case Report

Functional dissociation of brain neural activity induced by opening or closing the eyes has been well established. However, how the temporal dynamics of the underlying neuronal modulations differ between these eye conditions during movement-related behaviours is less known. Using a robotic-assisted motor imagery brain-computer interface (MI BCI), we measured neural activity over the motor regions with electroencephalography (EEG) in a stroke survivor during his longitudinal rehabilitation training. We investigated lateralized oscillatory sensorimotor rhythm modulations while the patient imagined moving his hemiplegic hand with closed and open eyes to control an external robotic splint. In order to precisely identify the main profiles of neural activation affected by MI with eyes-open (MIEO) and eyes-closed (MIEC), a data-driven approach based on parallel factor analysis (PARAFAC) tensor decomposition was employed. Using the proposed framework, a set of narrow-band, subject-specific sensorimotor rhythms was identified; each of them had its own spatial and time signature. When MIEC trials were compared with MIEO trials, three key narrow-band rhythms whose peak frequencies centred at ∼8.0 Hz, ∼11.5 Hz, and ∼15.5 Hz, were identified with differently modulated oscillatory dynamics during movement preparation, initiation, and completion time frames. Furthermore, we observed that lower and higher sensorimotor oscillations represent different functional mechanisms within the MI paradigm, reinforcing the hypothesis that rhythmic activity in the human sensorimotor system is dissociated. Leveraging PARAFAC, this study achieves remarkable precision in estimating latent sensorimotor neural substrates, aiding the investigation of the specific functional mechanisms involved in the MI process.
Theoretical analysis of oscillatory terms in lattice heat-current time correlation functions and their contributions to thermal conductivity

Lattice heat-current time correlation functions for insulators and semiconductors obtained using molecular dynamics (MD) simulations exhibit features of both pure exponential decay and oscillatory-exponential decay. For some materials the oscillatory terms contribute significantly to the lattice heat conductivity calculated from the correlation functions. However, the origin of the oscillatory terms is not well understood and their contribution to the heat conductivity is accounted for by fitting them to empirical functions. Here, a translationally invariant expression for the heat current in terms of creation and annihilation operators is derived. By using this full phonon-picture definition of the heat current and applying the relaxation-time approximation, we explain, at least in part, the origin of the oscillatory terms in the lattice heat-current correlation function. We discuss the relationship between the crystal Hamiltonian and the magnitude of the oscillatory terms. A solvable one-dimensional model is used to illustrate the potential importance of terms that are omitted in the commonly used phonon-picture expression for the heat current. While the derivations are fully quantum mechanical, classical-limit expressions are provided that enable direct contact with classical quantities obtainable from MD.
On Resumptive Pronouns in Chinese Relative Clauses: An LFG Approach

This current study provides an LFG approach to the resumptive pronoun phenomenon in Chinese relative clauses. We first reclassify the relativization in Chinese according to grammatical functions and then give a detailed syntactic analysis to the puzzles that arise, mainly, the optionality of overt resumptive pronouns of some grammatical functions, the Highest Subject Restriction (HSR) and the ANM Feature Hypothesis in the relativization of objects. Through our analysis we find that the optionality of overt RPs only occurs with core functions. A [PRED ‘pro’] value will be given to the corresponding grammatical function when an overt RP does not appear. We thus extend the Nonthematic Condition on Structure-Sharing to Anaphoric Binding and give a good explanation for the HSR phenomenon. Lastly, the ANM Feature Hypothesis challenges McCloskey’s generalization, namely, that resumptive pronouns are just ordinary pronouns.
Acute Changes in Right Ventricular Function in Pediatric Patients with Pulmonary Valve Stenosis Undergoing Percutaneous Valvuloplasty: A Speckle-Tracking Study

Introduction: Pulmonary valve stenosis determines multiple effects on the right ventricular dimension and function. Percutaneous balloon valvuloplasty is the treatment of choice in severe pulmonary valve stenosis in patients of all ages. However, little is known regarding right ventricular function immediate changes after percutaneous balloon dilation. Pediatric patients with isolated pulmonary valve stenosis represent a pure clinical model of chronic RV pressure overload not affected by other confounders or comorbidities. Aim of the study: This study seeks to explore right ventricle (RV) mechanics in pediatric patients early after percutaneous balloon pulmonary valvuloplasty (BPV) for valvar pulmonary stenosis (PS). Materials and Methods: Forty-three pediatric patients (19 males), mean age 3.2 ± 4.9 years old, with severe pulmonary valve stenosis and indication for percutaneous balloon valvuloplasty were recruited. All patients underwent standard transthoracic echocardiography (TTE), and speckle-tracking echocardiography (STE) with an analysis of right ventricle free-wall longitudinal strain (RVFWLS) one day before and one day after the procedure. For each patient, we collected invasive parameters during the interventional procedure before and after BPV. Results: After the procedure, there was an immediate significant reduction in both peak-to-peak transpulmonary gradient (peak-to-peak PG) and ratio between the right ventricle and aortic systolic pressure (RV/AoP) with a drop of ∆29.3 ± 14.67 mmHg and ∆0.43 ± 0.03, respectively. Post-procedural echocardiography showed peak and mean transvalvar pressure gradient drop (∆50 ± 32.23 and ∆31 ± 17.97, respectively). The degree of pulmonary valve regurgitation was mild in 8% of patients before the procedure, affecting 29% of our patients post-BPV (p = 0.007). The analysis of right ventricular mechanics showed a significant improvement of fractional area change (FAC) immediately after BPV (40.11% vs. 44.42%, p = 0.01). On the other hand, right ventricular longitudinal systolic function parameters, TAPSE and global RVFWLS, did not improve significantly after intervention. The segmental analysis of the RVFWLS showed a significant regional increase in the myocardial deformation of the apical segments. Conclusions: Percutaneous BPV represents an efficient and safe procedure to relieve severe pulmonary valve stenosis. The analysis of the right ventricular function on echocardiography demonstrated an immediate global systolic function improvement, while longitudinal systolic function was persistently impaired 24 h after intervention, possibly due to the necessity of a longer recovery time.
Effect of Health Education on Posture Practices Towards Reduction of Low Back Pain Among Patients in Rivers State

This study investigated the effect of health education on posture practices in reducing low back pain among patients in Rivers state, Nigeria. To achieve this, pretest-posttest quasi-experimental design was employed, and the study targeted 170 patients at the University of Port Harcourt Teaching Hospital in Nigeria. Two objectives having corresponding research questions and hypotheses guided the study, while convenience and stratified sampling techniques were used to select 50 participants, comprising 35 patients from the general outpatient clinic department and 15 patients from the spine physiotherapy unit, with 20 male and 30 female participants. Data collection was done by administering a self-structured, self-administered questionnaire, titled health education effect on ergonomic practices and low back pain, which had a reliability coefficient of 0.75. Both descriptive and inferential statistics were used to answer the research questions and test the hypotheses. The research found that educating patients on various methods of preventing low back pain, including healthy weight maintenance, warm-up exercises, and proper postural habits while sitting and standing, had a noteworthy impact on reducing pain. Moreover, the study also revealed that health education programmes were successful in therapeutic posture practices and reducing low back pain in patients residing in Rivers state. Therefore, the study concluded and recommended that health education interventions for functional and therapeutic posture practices are effective strategies for reducing low back pain among patients in Rivers state, and healthcare providers should incorporate these interventions into their treatment plans for patients suffering from low back pain.
Promoting Beneficial Arthropods in Urban Agroecosystems: Focus on Flowers, Maybe Not Native Plants

Simple Summary Urban sprawl contributes to biodiversity loss, but the presence of native plants in urban areas may help to support diversity. In urban gardens, where non-native plants are common, the role of native plants may be especially important in providing resources to pollinators and other beneficial arthropods, like natural enemies of pests, but little research has examined how native plants affect non-pollinators in gardens. We sampled plants, bees, and three groups of natural enemies (ladybeetles, ants, and ground-foraging spiders) in gardens in California. We found that native plants represented about 10% of the species and only 2.5% of the plants found. The native plants present did not have large impacts on the numbers or diversity of bees, ladybeetles, or ants, but did have an unexpected negative effect on non-native spiders. Other garden features, such as garden size, flowers, mulch, and trees and shrubs, did have mostly positive impacts on the biodiversity of bees, ants, and spiders, but the impacts of each feature differed by organism type. Natural habitat near to gardens was also important for native ants, non-native bees, and ladybeetles. In sum, native plants, when rare within gardens, likely have little benefit, but other garden features can be manipulated in order to promote beneficial arthropods in gardens. Abstract (1) Urbanization threatens biodiversity, yet urban native plants support native biodiversity, contributing to conservation and ecosystem services. Within urban agroecosystems, where non-native plants are abundant, native plants may boost the abundance and richness of beneficial arthropods. Nevertheless, current information focuses on pollinators, with little attention being paid to other beneficials, like natural enemies. (2) We examined how the species richness of native plants, garden management, and landscape composition influence the abundance and species richness of all, native, and non-native bees, ladybeetles, ants, and ground-foraging spiders in urban agroecosystems (i.e., urban community gardens) in California. (3) We found that native plants (~10% of species, but only ~2.5% of plant cover) had little influence on arthropods, with negative effects only on non-native spider richness, likely due to the low plant cover provided by native plants. Garden size boosted native and non-native bee abundance and richness and non-native spider richness; floral abundance boosted non-native spider abundance and native and non-native spider richness; and mulch cover and tree and shrub abundance boosted non-native spider richness. Natural habitat cover promoted non-native bee and native ant abundance, but fewer native ladybeetle species were observed. (4) While native plant richness may not strongly influence the abundance and richness of beneficial arthropods, other garden management features could be manipulated to promote the conservation of native organisms or ecosystem services provided by native and non-native organisms within urban agroecosystems.
