Objective

To report and compare the proportion of children with and without congenital anomalies undergoing gastrostomy for tube feeding in their first 5 years.

Methods

A European, population-based data-linkage cohort study (EUROlinkCAT). Children up to 5 years of age registered in nine EUROCAT registries (national and regional) in six countries and children without congenital anomalies (reference children) living in the same geographical areas were included. Data on hospitalisation and surgical procedures for all children were obtained by electronic linkage to hospital databases.

Results

The study included 91 504 EUROCAT children and 1 960 272 reference children. Overall, 1200 (1.3%, 95% CI 1.2% to 1.6%) EUROCAT children and 374 (0.016%, 95% CI 0.009% to 0.026%) reference children had a surgical code for gastrostomy within the first 5 years of life. There were geographical variations across Europe with higher rates in Northern Europe compared with Southern Europe. Around one in four children with Cornelia de Lange syndrome and Wolf-Hirschhorn syndrome had a gastrostomy. Among children with structural anomalies, those with oesophageal atresia had the highest proportion of gastrostomy (15.9%).

Conclusions

This study including almost 2 million reference children in Europe found that only 0.016% of these children had a surgery code for gastrostomy before age 5 years. The children with congenital anomalies were on average 80 times more likely to need a gastrostomy before age 5 years than children without congenital anomalies. More than two-thirds of gastrostomy procedures performed within the first 5 years of life were in children with congenital anomalies.

Background

The association between atrial fibrillation (AF) and the prognosis of acute ischaemic stroke (AIS) remains controversial; whether the recombinant tissue plasminogen activator dose influences this association remains poorly understood.

Methods

Patients who had an AIS were enrolled from eight stroke centres in China. According to the recombinant tissue plasminogen activator dose, patients treated with intravenous recombinant tissue plasminogen activator within 4.5 hours after symptom onset were divided into a low-dose group (recombinant tissue plasminogen activator <0.85 mg/kg) and a standard-dose group (recombinant tissue plasminogen activator ≥0.85 mg/kg). Patients who had an AIS in the low-dose group and the standard dose group were divided into whether or not they had AF. The main outcomes were major disability (modified Rankin scale (mRS) score 3–5), mortality and vascular events occurring within 3 months.

Results

The study included 630 patients who received recombinant tissue plasminogen activator after AIS, including 391 males and 239 females, with a mean age of 65.8 years. Of these patients, 305 (48.4%) received low-dose recombinant tissue plasminogen activator and 325 (51.6%) received standard dose recombinant tissue plasminogen activator. The recombinant tissue plasminogen activator dose significantly influenced the association between AF and death or major disability (p-interaction=0.036). After multivariate adjustment, AF was associated with an increased risk of death or major disability (OR 2.90, 95% CI 1.47 to 5.72, p=0.002), major disability (OR 1.93, 95% CI 1.04 to 3.59, p=0.038) and vascular events (HR 5.01, 95% CI 2.25 to 11.14, p<0.001) within 3 months in patients with standard-dose recombinant tissue plasminogen activator. No significant association was found between AF and any clinical outcome in patients with low-dose recombinant tissue plasminogen activator (all p>0.05). With AF, the mRS score distribution showed a significantly worse shift in patients with standard-dose recombinant tissue plasminogen activator (p=0.016) than in those with low-dose recombinant tissue plasminogen activator (p=0.874).

Conclusions

AF may be a strong predictor of poor prognosis in patients who had an AIS receiving standard-dose recombinant tissue plasminogen activator, suggesting that low-dose recombinant tissue plasminogen activator should be administered to patients who had a stroke with AF to improve their prognosis.

Fluoride ion sensing with an acridinium borane
Authors: Liu Wei-Chun , Gabbaï François P.
Published: June 2022

With our continuing interest in the chemistry of cationic boranes, we have synthesized the tetrafluoroborate salt of 1-dimesitylboron-4-( N-methyl-9-acridinium)-phenylene, which acts as a turn-on fluoride anion sensor, visibly changing from yellow to orange upon binding fluoride. To understand this reactivity, we spectroscopically and computationally analyzed the cation and fluoroborate adduct. Ultraviolet–visible spectroscopy and time-dependent density functional theory calculations revealed the basis of the color change to be a low energy redshift in a intramolecular charge transfer band. Electrochemical studies were undertaken to further probe this system. Cyclic voltammetry indicated a reversible one-electron reduction for the cation and a cathodic shift of −0.12 V in the first reduction wave upon fluoride binding. Chemical reduction of the cation yielded the acridine borane radical, which was verified by electron paramagnetic resonance spectroscopy.

Bionanotechnology approaches are used by researchers to create nanoparticles and nanomaterials in an environmental friendly and cost-effective manner. Because of biologically active plant secondary metabolites that aid in green synthesis, as well as their specific biological applications, biosynthesized nanoparticles are gaining traction. This work describes a simple, eco-friendly, dependable and cost-effective method for making silver nanoparticles from aqueous leaf extract of Psychotria octosulcata, as well as their anti-inflammatory properties in vitro. UV-Visible spectroscopy, Fourier Transform Infrared spectroscopy (FTIR), X-ray diffraction (XRD), Scanning electron microscopy (SEM) and Zeta potential (ZP) were used to analyze the biosynthesized Psychotria octosulcata silver nanoparticles. Under a scanning electron microscope, the silver nanoparticles had a spherical shape and sizes ranging from 1 to 100 nm. The peaks from the Fourier Transform for the functional groups C=O, –C=C, C–H and OH in the infrared spectroscopy spectra of silver nanoparticles demonstrate the stability of the produced silver nanoparticles. The particles were crystalline and had a face-centered cubic structure with broad peaks in nature, according to the XRD studies. Protein denaturation was used to test the anti-inflammatory activity of the synthesized silver nanoparticles in vitro.
Symmetry evolution for the imperfect fluid under perturbations
Authors: Garat Alcides
Published: June 2022

Ever since a new symmetry was found for the imperfect fluid with vorticity, the question of the effect of perturbations on the symmetry itself has been raised. This new symmetry arose when realizing that local four-velocity gauge-like transformations would render the left-hand side of the Einstein equations invariant because the metric tensor would be invariant under this new kind of local transformations. Then the point was raised about the invariance of such a kind of transformations of the stress–energy tensor on the right-hand side of the Einstein equations in curved four-dimensional Lorentz spacetimes. It was verified that these invariances do not work with plain perfect fluid but they do work for imperfect fluids. The imperfect fluid stress–energy tensor will be invariant under local four-velocity gauge-like transformations when additional transformations are introduced for several variables included in the stress–energy tensor itself. This local invariance was also the criteria introduced in order to present a new stress–energy tensor for vorticity as well. New tetrads are at the core of the realization of the existence of this new symmetry because it is through these new tetrads that this new symmetry is realized. It is through the local transformation of these new tetrad vectors that we can prove that the metric tensor is invariant. This new kind of symmetry has its origins in a similar tetrad formulation as to the Einstein–Maxwell spacetimes formalism presented in previous manuscripts. In this paper, we will introduce local perturbations by external agents to the relevant objects in the imperfect fluid geometry. We will demonstrate a theorem that proves that the symmetries under four-velocity gauge-like transformations will be instantaneously broken but at the same time transformed into new symmetries. Because the local orthogonal planes determined by these new tetrads, which happen to be the local planes of symmetry will tilt under local perturbations. There will be a symmetry evolution under perturbations.

Authors: Lin Qiuping , Dong Xiaoxue , Li Minglun
Published: June 2022

At present, machine learning is more efficient and accurate for the efficiency of operation logic after four stages of reform. In order to improve the participation rate of the whole people in track and field sports and get a better level and ranking in track and field competitions, the ATI model under the machine model is used to deeply analyze the behavior of track and field sports in order to get more accurate data. There are a series of problems in the process of correlation analysis, such as the loss caused by the analysis process, the error in the analysis process, and the lack of understanding of track- and field-related data. In order to solve this series of problems, this study optimizes the behavior analysis through related experiments. The experiment proves the correlation between learning rate and loss. When the learning rate is 0.1, the loss caused by behavior analysis is lower. For the 23rd–28th session, the number of gold medals and the number of medals won in track and field were analyzed. By comparing the ATI model with the ATT model, ATT-Net model, and WAT model, it is concluded that the ATI model has a lower error rate for behavior analysis under big data. The coverage rate of behavior analysis data is wider. Therefore, in order to make track and field behavior analysis more accurate and stable under big data, the ATI model under machine learning should be preferred for data collection, collation, analysis, and summary. Through the ATI model to analyze the related behavior of track and field under big data, there are the following advantages: when the learning speed is 0.1, the loss value in the analysis process is reduced; the number of neurons is increased, and the dropout rate is reduced to reduce NPMSE value; and the error loss rate of behavior analysis is reduced, and the analysis coverage rate is increased.

Published: June 2022

Using the micro model plus full-information scanning video, it can vividly and intuitively reproduce the fluid movement during the oil, gas, and water displacement process and the microscopic remaining oil morphology and distribution after the water flooding is completed. Based on the microfluidic flat plate model experiment, this paper discusses the microresidue comprehensively for the specific development well pattern (inverse seven-point well pattern), well type, and fracture occurrence morphology (horizontal fracture) produced by fracturing, taking into account the comparative displacement method, the law of effective use of oil. The research results show that the effect of nitrogen flooding and foam flooding in horizontal fractured conventional wells is better than that of water flooding. The remaining oil after nitrogen flooding and foam flooding is mainly columnar and plug; the remaining oil of water flooding is mainly striped and networked. And the remaining oil saturation is high (72.2%). The main reason for this type of remaining oil is that there is still a large amount of contiguous remaining oil that has not been used; the horizontal fracture horizontal well has the best nitrogen flooding effect, and the remaining oil saturation is low (25.48%), the remaining oil form after nitrogen flooding is mainly striped, the remaining oil content of the other types is low, and the remaining oil form after water flooding is mainly columnar and net.
Accounting of Air Pollution on Tourism Economic Loss in Fuzhou Based on Big Data Analysis
Authors: Zhu Hong
Published: June 2022

When measuring the overall image of a city, air quality is one of the main indicators which is closely related to the quality of life. For a city, it is also a concrete manifestation of the tourist attraction ability. Air pollution in urban areas has already had an important impact on the daily lives of residents. It not only has a direct impact on human health but also affects human emotions, travel consumption, outdoor activities, and other aspects, thereby affecting economic vitality. Since air quality is a core indicator to measure the comprehensive image of a city, in order to effectively increase people’s sense of experience and enhance the local tourist attraction ability, this paper studies the air pollution impact on tourist cities. When exploring the impact of Fuzhou’s scenic spots and tourism frequency on air pollution, the number of scenic spots and reviews published on the Meituan software from 2018 to 2019 is selected as the research object. In the actual analysis, tourist attractions are divided into tourist attractions selected by people outside of Fuzhou and tourist attractions selected by residents. The empirical results show that the frequency of local travel will be reduced by 0.090 percentage points for every one percentage point increase in the air quality index. It can be calculated that the annual local travel due to the increase in the air quality index will reduce the number of tourist attractions in Fuzhou by approximately 2.4511 million. Every time the air index rises by 0.164 percentage points, the corresponding annual reduction in tourists is 11.733 million. Through the analysis of these 6 scenic spots, it can be concluded that whether it is scenic spots suitable for local people’s tourism or scenic spots for tourists from all over the world, air pollution will reduce the frequency of scenic spots travel, which will cause urban tourism economic losses. Through the research of related theoretical data, it can be found that haze weather and air pollution have a negative impact on Fuzhou’s scenic spot income and tourism growth rate. At the same time, air pollution will also affect the comfort of the city and then have a negative impact on the city’s investment environment and the living environment, which will affect the city’s economic development and other aspects of construction.

Sudden public health and medical education events have tested the stability of society to a great extent. The government need to strengthen capacity building, make use of system dynamic supervision, warn public health events in advance, and minimize the impact scope and related harmfulness of events. This not only facilitates the rapid mobilization of resources by the later government but also facilitates the comprehensive and detailed deployment and arrangement of decision-makers. As we all know, the Internet of Things is used by all walks of life because of its outstanding advantages of low power consumption, low cost, and wide range. Therefore, this article takes the Internet of Things as the technical basis of the system. According to the actual demand and resource design, it includes two system functions: detection and early warning. The results show that: (1) considering the practical principle, the evaluation system interface found that the scores of font size and color style are all below 80%, which need to be optimized and adjusted; the overall interface basically meets the needs of users. (2) The throughput of the three methods is different. The CoAP-E has superior throughput. (3) With the increase in packet loss rate, the request success rate of the CoAP method decreases in a “drop” manner. The CoAP-E method in this article has the best performance. (4) When the packet loss rate is 25%, the network adaptability of this method is the strongest, and the retransmission rate is less than 18%; the CoAP method is as high as 35%. (5) When the number of concurrent requests is less than 2500, there is no obvious difference between the three methods; the optimal performance of the dynamic load balancing method is 10.1 s. (6) The system comprehensively considers various factors of five site selections. The highest comprehensive score of Final Site, 5 is 8.7, which can be used as the resettlement place of emergency rescue facilities. This article starts from the characteristics and needs of public emergencies, and the final set of the system runs well. It can quickly reflect public health emergencies and medical education events. Use the most effective system functions for risk control, and maximize the analysis, organization, and coordination of events. The follow-up optimization of system details needs to be studied.

Authors: Zhang Jing , Qiu Shi , Cui Xiaohai , Liang Ting
Published: June 2022

Pulmonary nodules have been found as the main pathological change in the lung. Signs of pulmonary nodule lay the major basis for the recognition of the benign and malignant of pulmonary nodules. The spiculation of pulmonary nodules is one of the main signs. Pulmonary nodules are small in volume, so they are difficult to extract accurately. Moreover, the number of spiculation samples is limited, so it is difficult to build a stable network structure. Thus, a novel pulmonary nodule spiculation recognition algorithm is proposed. MCA (morphological component analysis) model is built to segment pulmonary nodules in accordance with the composition of pulmonary CT images. Subsequently, the maximum density projection mechanism is introduced to characterize the boundary features of pulmonary nodules to the maximum extent. Inspired by time series dynamic programming, this paper proposes DTW (dynamic time warping) distance to measure data similarity. Lastly, a semisupervised generative adversarial network is built to solve the problem of insufficient positive samples, and it is capable of recognizing pulmonary nodule spiculation. As revealed by the experimental result, the proposed algorithm exhibited strong robustness.

Published: June 2022

In order to realize the stable operation of the DC microgrid, a hierarchical coordinated control method of the DC microgrid based on the recursive fuzzy neural network algorithm is designed in this article. Based on the analysis of the working mode and topology of the DC microgrid, the droop control coefficient is calculated through power flow calculation, and then, a three-layer control strategy is designed combined with a hierarchical coordinated control algorithm to realize the distributed coordinated control of DC microgrid. Combined with the recursive fuzzy neural network algorithm, the real-time amplitude limiting and convergence of the output of the distributed coordination controller are realized. Experimental results show that under the control of this method, the changes in current and voltage at each port of the DC microgrid are relatively stable during off-grid switching. In addition, this method effectively reduces the fault rate of power grid lines, which fully proves the feasibility and reliability of this method.

Authors: Han Dayong , Yang Chao , Wang Liang , Li Dong , Liu Yang
Published: June 2022

In this paper, the 3D continuum-discrete coupling analysis method combined with the strength reduction theory is used to study the macrodeformation, stress law, and microfracture mechanism of a high and steep cutting slope of Zhongkai Expressway in Guangdong Province. The 3D continuum-discrete coupling slope model is established based on the finite difference software FLAC and the discrete element program PFC. Then, based on the correlations between stress tensor and force chain, displacement and shear strain increment, plastic deformation, and microfracture, the mechanism of slope instability is analyzed from macro- and microscales. The research shows the following: (1) the continuum-discrete coupling model is reasonable and effective in the three-dimensional slope stability analysis. (2) The coupling domain was penetrated by the shear band, and the upper part displacement of the coupling domain was large, whose direction was basically consistent with the shear band direction; thus, the slope slip surface was formed. (3) The microfracture can represent the macroscopic failure phenomenon, and the slope landslide can be interpreted as the result of shear fracture in slip direction, accompanied by the extension and penetration of tension crack.

Authors: Daba Bana , Mekonnen Getachew
Published: June 2022

A field experiment was conducted in Bench Maji Zone at Guraferda district during the 2020 main cropping season to assess the effect of row spacing and frequency of weeding on weeds, yield components, and yield of rice and to estimate the economic feasibility of weed control practices of rice. Factorial combination of three-row spacing (20, 25, and 30 cm) and six weeding frequencies (one-hand weeding and hoeing at 2, 3, and 4 weeks after emergence, two-hand weeding and hoeing at 2 and 5 weeks after emergence, and weed-free check and weedy check) were laid out in randomized complete block design with three replications. Weed control efficiency, days to 50% heading, days to 90% physiological maturity, plant height, and straw yield were significantly affected by weeding frequencies but not by row spacing. Significantly higher panicle length (24.07 cm), number of productive tillers (209.08 m−2), number of kernels per panicle (252.22), grain yield (4303.0 kg·ha−1), aboveground dry biomass (10295.4 kg·ha−1), and harvest index (40.79%) were observed under 25 cm row spacing, compared with 20 and 30 cm. Significantly higher panicle length (25.81 cm), number of productive tillers (257.71 m−2), number of kernels per panicle (172.33), thousand kernels weight (35.44 g), grain yield (5226.7 kg·ha−1), aboveground dry biomass (11696.3 kg·ha−1), and harvest index (44.92%) were recorded under complete weed-free check plots. However, the highest net return (46,394.87 ETB·ha−1) was obtained from the combination of 25 cm row spacing and two-hand weeding and hoeing at 2 and 5 weeks after emergence, as the cost of maintaining weed-free plots was much higher. Thus, practicing two-hand weeding and hoeing at 2 and 5 WAE and 25 cm row spacing was found to be both agronomically and economically feasible for Rice (NERICA-4) production in the Guraferda area.

Objective. The incidence of cervical cancer is high, which seriously threatens the life and health of women. At present, there were few studies on the application of family-oriented enabling psychological nursing in patients with cervical cancer. So, the purpose of this study was to explore the effect of family-oriented enabling psychological nursing on posttraumatic stress and fear of recurrence in patients with cervical cancer. The clinical data of 236 patients with cervical cancer treated in our hospital from January 2020 to December 2021 was retrospectively analyzed. According to different nursing methods, they were assigned to convention group (105 cases accepted the conventional nursing) and psychology group (131 cases accepted the family-oriented enabling psychological nursing). The PTSD Checklist-Civilian Version (PCL-C) scores, Fear of Progression Questionnaire-Short Form (FoP-Q-SF) scores, Cancer Rehabilitation Evaluation System-Short Form (CARES-SF) scores, and satisfaction rates of the two groups were compared. It turned out that the PCL-C score, FoP-Q-SF score, and CARES-SF score decreased in the psychology group and the convention group (

P
<
0.05

) and the decreases of those three scores were more obvious in the psychology group. In comparison with the convention group, the nursing satisfaction rate of psychology group was higher (96.18% vs. 76.19%,

P
<
0.05

). It could be concluded that family-oriented enabling psychological nursing had definite clinical application value in patients with cervical cancer, which could alleviate the symptoms of posttraumatic stress disorder and reduce the fear of recurrence, stabilize the perioperative psychological state, facilitate treatment, and improve the quality of life and satisfaction rate of patients and was worthy of promotion and application.

Objective. To investigate the correlation between Chinese medicine syndrome and cognitive dysfunction in patients with mild cognitive impairment (MCI). Methods. 121 MCI patients were included for syndrome differentiation and syndrome scoring according to the Chinese medicine syndrome classification standard of senile dementia. The cognitive function and cognitive subitems (including visual space and executive function, naming, attention, language, abstraction, delayed recall, and orientation) of patients with different Chinese medicine syndromes were scored with the Montreal Cognitive Assessment (MoCA). Correlation analysis was made on Chinese medicine syndromes and cognitive domain damage. Results. Chinese medicine syndromes from most to least were kidney deficiency and marrow reduction syndrome, turbid phlegm obstructing orifices syndrome, deficiency of heart and spleen syndrome, qi stagnation and blood stasis syndrome, and yin deficiency of heart and liver syndrome. There were no significant differences in MoCA scores among different Chinese medicine syndromes (

P
>

).In the kidney deficiency and marrow reduction syndrome, the delayed recall score was 1.74 ± 1.23 and the difference was statistically significant when compared with deficiency of heart and spleen syndrome or the yin deficiency of heart and liver syndrome (

P
<
0.05

). In the turbid phlegm obstructing orifices syndrome, the delayed recall score was 1.81 ± 1.33 and the difference was statistically significant when compared with the yin deficiency of heart and liver syndrome (

P
<
0.05

). There was a significant negative correlation between the kidney deficiency and marrow reduction syndrome’s Chinese medicine syndrome scores and MoCA scores (

P
<
0.01

), and there was a negative correlation between the turbid phlegm obstructing orifices syndrome’s Chinese medicine syndrome scores and MoCA scores (

P
<
0.05

). Correlation analysis showed that the kidney deficiency and marrow reduction syndrome was significantly negatively correlated with delayed recall scores (

P
<
0.01

), and it was also negatively correlated with visual space and executive function scores (

P
<
0.05

). The turbid phlegm obstructing orifices syndrome was significantly negatively correlated with delayed recall scores (

P
<
0.01

). Conclusion. The kidney deficiency and marrow reduction syndrome and the turbid phlegm obstructing orifices syndrome were the most common syndromes in MCI. Patients with kidney deficiency and marrow reduction syndrome might have obvious damage in delayed recall function and have damage in visual space and executive function. Patients with turbid phlegm obstructing orifices syndrome might have obvious damage in delayed recall function.

Nowadays, laser processing technology is being used more and more in various fields, and the requirements for laser control procedures are getting higher and higher. This paper aims to study the path generation problem of laser marking technology in order to improve the efficiency of laser marking as well as the protection of the marking material. Therefore, we creatively propose two-path generation methods, namely, sawtooth parallel and contour parallel, and design the boundary curve offset algorithm and domain partition intersection algorithm for the computer simulation of the two marking paths, respectively. Through the simulation, we discussed the efficiency and marking quality of the two path generation methods and gave the conclusion that the efficiency of the sawtooth parallel path generation method is greater than that of the contour parallel path generation method under specific parameters.
Bifurcation Analysis and Synchronous Patterns between Field Coupled Neurons with Time Delay
Authors: Zhang Li , An Xinlei , Zhang Jiangang , Shi Qianqian
Published: June 2022

Neurons encode and transmit signals through chemical synaptic or electrical synaptic connections in the actual nervous system. Exploring the biophysical properties of coupling channels is of great significance for further understanding the rhythm transitions of neural network electrical activity patterns and preventing neurological diseases. From the perspective of biophysics, the activation of magnetic field coupling is the result of the continuous release and propagation of intracellular and extracellular ions, which is very similar to the activation of chemical synaptic coupling through the continuous release of neurotransmitters. In this article, an induction coil is used to connect two HR neurons to stimulate the effect of magnetic field coupling. It is inevitable that time delays can affect the coupling process in the transmission of information, and it should be considered in the coupled model. Firstly, the firing characteristics and bifurcation modes of two coupled HR neurons are studied by using one parameter and two parameters bifurcation. With the increase of propagation delay and coupling gain, the chaotic state of neurons disappears and the high‐period window decreases due to the influence of energy transfer between neurons. Then, the synchronization patterns of two HR neurons with different stimulation are analyzed by error diagrams and time series diagrams. It is confirmed that the synchronous pattern has certain regularity and is related not only to the neurons with large stimulation current but also to the time delay and coupling gain. The research conclusions of this article will provide the corresponding theoretical basis for medical experiments.

Authors: Yue Ya
Published: June 2022

Music education is an essential and significant link in a quality education, as it can assist pupils improve their integrity and nurture noble character. The evident distinction between music teaching and teaching in other disciplines is that music teaching can provide aesthetic education to students in order to improve students’ self-cultivation and overall temperament and basically play a role in developing people in a holistic fashion. Note detection is an important content in music teaching. Instrument tuning, computerized score recognition, music database search, and electronic music synthesis all benefit greatly from note detection technologies. In note detection, there are problems such as difficult one-to-one correspondence between estimated pitches and standard frequencies, a narrow range of identifiable pitches, poor robustness of the recognition process, and low recognition rate. In this context, this work proposes an automatic note detection in music teaching based on deep learning. It uses a convolutional neural network (CNN) and a bidirectional long-short-term memory (BiLSTM) network to build a deep neural network model, called convolutional neural network Bidirectional Long Short-Term Memory (CNN-BiLSTM), using this network to conduct in-depth research on note detection. First, based on the current research status, a deep neural network model based on CNN and BiLSTM is proposed to detect musical notes. The network can independently mine and learn the deep-level features of music signals and has better feature extraction and generalization capabilities. Second, the experimental results are evaluated using different evaluation metrics.

Background. Membranous nephropathy (MN) is a disease that affects the basement membrane of the glomeruli of the kidney resulting in proteinuria. The concurrent incidence of vasculitic glomerulonephritis and MN in the same patient is unusual. Herein, we report a case with this unusual combination. Case. Our patient is a 53-year-old Hispanic male with a medical history of tobacco use, type 2 diabetes mellitus, and hypertension who presented with hematuria and was found to have nephrotic range proteinuria and renal impairment. Blood workup revealed positive ANCA serology, which led to a renal biopsy that showed crescentic vasculitis in addition to membranous nephropathy. The patient was started on intermittent hemodialysis (HD) and treated initially with intravenous (IV) pulse steroids; subsequently, oral prednisolone and IV cyclophosphamide were initiated. The patient remained HD dependent at the time of discharge with the resolution of hematuria. A follow-up with an outpatient nephrology clinic was arranged. Conclusion. Membranous nephropathy complicated by crescentic glomerulonephritis has a more aggressive clinical course and decline in renal function compared to MN alone which can lead to initiating renal replacement therapy. However, immunosuppressive drugs can result in significant improvement of renal function if started early enough.

Studies show that prestressed anchor cable antislide piles have good antiseismic characteristics. As an important parameter in the design of anchor-cable piles, the effect of anchor-cable inclination on the seismic response of the anchor-cable pile system has been rarely studied so far. In the present study, the seismic response characteristics of the anchor-pulled pile under different cable inclinations are studied using a large-scale seismic model test platform and numerical methods. The obtained results show that the inclined angle of the anchor cable has a great influence on the seismic response of the pile-anchor system. It is found that under the same seismic conditions, the axial force of the anchor cable becomes smaller as the anchor dip angle increases, while the pile top displacement becomes larger. The dynamic earth pressure behind the pile changes from the sliding surface to the pile top, indicating that the earth pressure near the sliding surface and the pile top is of active and passive earth pressure types, respectively. This pressure decreases with the increase of the anchor dip angle, thereby affecting the performance of the antisliding pile.
Gated Recurrent Unit Framework for Ideological and Political Teaching System in Colleges
Authors: Mu Yang
Published: June 2022

College ideological and political education has always been the primary content of national spiritual civilization construction. The current teaching methods are more flexible, resulting in the quality of ideological and political teaching not being reasonably assessed. To address this problem, we propose a method for assessing the quality of ideological and political teaching based on the gated recurrent unit (GRU) network and construct an automatic assessment system for ideological and political teaching. We draw on the migration learning model to improve the loss function by using the generalized intersection set over the joint loss function to compensate for the shortcoming of the small number of ideological and political teaching datasets. We use a masking algorithm to enhance the local features of teaching data sequences for different classes of ideological and political teaching quality assessment metrics. In addition, we use the minimum outer matrix algorithm to extract the sequence features of different assessment dimensions to improve the accuracy of the model for the quality assessment of ideological and political teaching. To meet the quality assessment conditions of ideological and political teaching, we compiled and produced ideological and political teaching datasets according to the teaching data coverage. The experimental results proved that our method performed best in comprehensive quality assessment accuracy in ideological and political teaching, with the assessment accuracy rate above 90%. Compared with traditional machine learning methods and deep learning methods, our method has higher accuracy and better robustness.
Obstetric red cell transfusion in a high-volume tertiary hospital: a retrospective cohort study
Authors: Lew Eileen , Lional Karuna Mary , Tagore Shephali
Published: June 2022

Introduction:

Red cell transfusion is expensive and not without risks. Despite the availability of transfusion guidelines, studies report a wide interhospital variation in transfusion rates. This retrospective cohort study was conducted to define the incidence of red cell transfusion in a multi-ethnic obstetric population and to evaluate current transfusion practice with regard to indications and appropriateness.

Methods:

All parturients who delivered a live or stillbirth in the period 2014–2015 and who received allogeneic blood transfusion during pregnancy and up to six weeks postnatally were identified. Their medical records were reviewed to extract the relevant demographic, obstetric and transfusion data. Descriptive analysis of data was performed using IBM SPSS Statistics software.

Results:

Out of 23,456 parturients who delivered in the study period, 760 were administered red cell transfusion, resulting in a transfusion rate of 3.2% or 32 in 1,000 maternities. A total of 1,675 red cell units were utilised in 863 transfusion episodes. Major indications for transfusion were anaemia in pregnancy (49.2%) and postpartum haemorrhage secondary to an atonic uterus. Transfusion was more frequently associated with caesarean than vaginal births (4.9% vs. 2.4%). About 14% of transfusions were initiated with pre-transfusion haemoglobin (Hb) ≥8.0 g/dL, whereas 37% of transfusions resulted in post-transfusion Hb >9.0 g/dL.

Conclusion:

The incidence of red cell transfusion was 3.2% in a multiethnic obstetric population. Patient blood management strategies should focus on optimising antenatal anaemia, reducing blood loss during delivery and eliminating inappropriate transfusion.
Cognitive profile in mild cognitive impairment with Lewy bodies

Published: June 2022

Introduction:

This study aimed to elucidate the cognitive profile of patients with mild cognitive impairment with Lewy bodies (MCI-LB) and to compare it to that of patients with mild cognitive impairment due to Alzheimer’s disease (MCI-AD).

Methods:

Subjects older than 60 years with probable MCI-LB (n = 60) or MCI-AD (n = 60) were recruited. All patients were tested with Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) to assess their global cognitive profile.

Results:

The MCI-AD and MCI-LB patients did not differ in total MMSE and MoCA scores. However, some sub-items in MMSE and MoCA were shown to be screening markers for differentiating MCI-LB from MCI-AD. In the visuoconstructive test, the total score and hands subitem score in the clock-drawing test were significantly lower in MCI-LB than in MCI-AD. As for the executive function, the ‘animal fluency test’, ‘repeat digits backward test’ and ‘take paper by your right hand’ in MMSE all showed lower scores in MCI-LB compared with MCI-AD. As for memory, ‘velvet’ and ‘church’ in MoCA and ‘ball’ and ‘national flag’ in MMSE had lower scores in MCI-AD than in MCI-LB.

Conclusion:

This study presents the cognitive profile of patients with MCI-LB. In line with the literature on Dementia with Lewy bodies, our results showed lower performance on tests for visuoconstructive and executive function, whereas memory remained relatively spared in the early period.
Reflecting Ancient Ethics
Authors: Smith Dain Alexander
Published: June 2022

Scholars usually interpret 1 Cor 13:12 as depicting an eschatological encounter with God because of the repetition of ἄρτι … τότε and the verbal shift from present to future. Additionally, scholars propose that the implied object of βλέπομεν is God, and humanity will see God πρόσωπον πρὸς πρόσωπον. However, New Testament scholarship has struggled to explain the mirror metaphor, δι’ ἐσόπτρου ἐν αἰνίγματι. Scholars argue it is depicting: indirect theophany, mystery religion initiation, or philosophical agnosticism. Conversely, this article argues that 1 Cor 13:12 and the mirror metaphor is best understood within the socially charged discourse of virtue, ethics, and imitation.
