Management for Patient with Asthma in Lumbal Canal Stenosis Using General Anesthetic and Epidural Analgetic: A Case Report
Authors: Welly Julian , Senapathi Tjokorda Gde Agung
Published: November 2023

Background: Lumbar canal stenosis, which often occurs concurrently with degenerative spondylolisthesis (DS), is characterized by low back and leg pain. The treatment of high-degree spondylolisthesis is by surgery, which is a combination procedure of decompression and fusion. Surgical patients with a history of uncontrolled asthma three months before surgery had nearly double the risk of postoperative mortality. Case presentation: A 53-year-old male patient was diagnosed with Lumbal Canal Stenosis ec HNP at levels L2-l3, L3-l4, L4-l5, L5-s1 Spondylolisthesis at level L4-l5 Meyerding grade 1 Spondylosis Lumbalis. The patient has a history of mild intermittent bronchial asthma, which was diagnosed 2 years ago. The patient was planned for Decompression-Stabilization-Fusion surgery, with the anesthesia plan being general anesthesia prone position with epidural analgesia. Conclusion: Combined general anesthesia (GA) and epidural analgesia (EA) for major surgery due to excellent pain control, reduced perioperative morbidity, and even reduced mortality compared with systemic analgesia. For surgical patients who have a history of asthma, determining whether a patient's asthma is well-controlled or poorly controlled is key to mitigating perioperative complications.

Authors: Rahmawati  , Mirna  , Fadjriah Ohorella  , Amina Ahmad
Published: November 2023

Anemia poses a significant health problem in developing countries, particularly among pregnant women who experience a high morbidity rate. Globally, anemia ranks third among pregnant women, with a prevalence rate of 74%. The primary causes of anemia cases are iron deficiency and acute bleeding, which interact with each other.This study employed an experimental research design known as quasi-experimental. The treatment or intervention was administered to the respondents who were divided into two groups: the control group, which did not receive the treatment, and the intervention group, which did. Prior to the intervention, both groups underwent an initial examination. Subsequently, the intervention group was given sweet potato leaf decoction, followed by a post-administration examination.The results obtained from the SPSS test demonstrated significant changes in hemoglobin levels among 15 respondents in the intervention and control groups. The test yielded a p-value of 0.000, with p < α (α < 0.005), indicating a significant alteration in hemoglobin levels before and after administering sweet potato leaves to pregnant women with anemia. Moreover, the independent test revealed a p-value of 0.005, with (α < 0.005), highlighting a significant difference between the intervention and control groups. This research endeavor aims to enhance knowledge and comprehension regarding the benefits of sweet potato leaves, particularly for healthcare professionals. Sweet potato leaves serve as a viable alternative in increasing hemoglobin levels among pregnant women with anemia.
Derivation of Key Characteristics of Columns in Frames with Sway
Authors: Hellesland Jostein
Published: November 2023

The paper paper examines columns of elastic frames that are able to displace laterally under axial load. Columns on the same level (story) of such frames may contribute to lateral support (stability) or require lateral support (supported columns). In the former case, maximum moments will occur at column ends, but may occur between column ends in the latter case. The column response, including the formation of moments and shears, is often complicated, often calling for approximate analysis methods and information that presently may not be readily available. Main attention of the paper is paid to providing results that will be helpful in providing, in a rather simple manner, improved understanding of column mechanics, and that may be helpful also as a supplement to full second-order analyses. Towards this goal, the major objective of the paper is threefold: (i) to identify characteristic points, or behavioral“landmarks” in the axial load-moment solution space, through the study of rotationally restrained elastic columns and two-column panels with sidesway; (ii) to derive simple, novel, closed-form expressions for these, thereby providing a tool simplifying the establishment of the variation of end and maximum moments versus axial load; (iii) to identify to what extent isolated (single) column analyses may adequately represent horizontally interacting columns, and potential unwinding, in frames.
Mercantilização do trabalho intelectual e a fuga de cérebros do Brasil
Authors: Fargoni Everton Henrique Eleutério , Silva Júnior João dos Reis
Published: November 2023

Neste trabalho, apresentamos uma síntese do significado global do fenômeno da fuga de cérebros para compreender seus efeitos no âmbito científico brasileiro. Para tanto, visamos esclarecer o funcionamento do trabalho científico no Brasil diante de outro fenômeno, a mundialização da ciência. O pesquisador no compromisso com a ciência, ao internacionalizar e desenvolver seu trabalho, vive contradições na imersão com culturas que se entrecruzam. No entanto, esse intelectual trabalha sob novas tendências globais criadas pela ciência mundializada, circunstância que pode submetê-lo ao extremo da exploração de suas capacidades técnicas articulado com a perda de sua autonomia de pesquisa e a escolha de seu objeto. Para refletir sobre esses acontecimentos, tomamos como base estudos teóricos que justificam o conceito e o movimento da fuga de cérebros, discutindo o trabalho intelectual no capitalismo. Transitamos pelos âmbitos político, econômico e da ciência para concluir a análise do colapso da ciência brasileira e os motivos que contribuem para a mercantilização do conhecimento e evasão de cientistas do país.
Mais do mesmo ou ameaças renovadas? Uma análise de recentes iniciativas brasileiras inspiradas nas escolas charter
Authors: Nazareth Henrique Dias Gomes de
Published: November 2023

Escolas charter nos Estados Unidos da América são entendidas como públicas, mas gerenciadas por entes privados. No Brasil, existem formas de privatização semelhantes há décadas, como as escolas conveniadas. A partir de 2015, surgiram projetos inspirados nas escolas charter que apresentam diferenças em relação aos convênios. Podem ser citados: os Contratos de Gestão na educação de Goiás; as Escolas Comunitárias de Porto Alegre; e o Projeto Somar de Minas Gerais. O principal objetivo aqui é analisar as diferenças entre convênios, charter e “charter brasileiras”, a fim de compreender as iniciativas citadas. Foi realizada uma análise documental em textos normativos, tais como editais, termos de colaboração e termos de fomento; e textos informativos, como notícias publicadas nos sítios oficiais das secretarias de educação e entrevistas para jornais. Ao contrário dos convênios, que se justificam pela incapacidade de oferta estatal, as iniciativas são marcadas pelo discurso da inovação e da eficiência e são propostas como estratégias para melhorar os índices de proficiência. Conclui-se que os projetos apresentam obstáculos para a efetivação do direito à educação. As diferenças entre as charter brasileiras e os convênios, apesar de sutis, possibilitam que as charter avancem sobre espaços que os convênios não ocupam.
Synthesis of photo- and ionochromic N-acylated 2-aminomethylenebenzo[b]thiophene-3(2Н)-ones with a terminal phenanthroline group
Authors: Rybalkin Vladimir P , Zmeeva Sofiya Yu , Popova Lidiya L , Dubonosova Irina V , Karlutova Olga Yu , Demidov Oleg P , Dubonosov Alexander D , Bren Vladimir A
Published: November 2023

A series of N-acylated 2-aminomethylenebenzo[b]thiophene-3(2Н)-ones with a terminal phenanthroline receptor substituent was synthesized. Upon irradiation in CH3CN or DMSO with light of 436 nm, they undergo Z/E isomerization around the C=C bond followed by rapid N→O migration of the acyl group and the formation of non-emissive O-acylated isomers. These isomers were separated preparatively and fully characterized by IR, 1H, 13C NMR, HRMS and XRD methods. The reverse thermal reaction is catalyzed by protonic acids. N-Acylated compounds exclusively with Fe2+ ions form non-fluorescent complexes with a contrast naked eye effect - color change of the solutions from yellow to pink-crimson. Subsequent selective interaction with acetate anions leads to the restoration of the initial absorption and emission spectra. Thus, the obtained compounds represent dual-mode “on-off-on” switches of optical and fluorescent properties under sequential exposure to light/H+ or sequential addition of Fe2+/AcO- ions.
Does Promoter Ownership Affect Dividend Policy? An Agency Problem Perspective
Authors: Singh Geeta , Kumar Satish , Pathak Rajesh , Bhattacharjee Kaushik
Published: November 2023

In this paper, we show a nonlinear relation between promoter ownership and dividends in the Indian context, that is, promoters pay more dividends at lower level of their ownership while they pay lesser dividends when their ownership increases beyond a threshold. In particular, we find that the adverse impact of promoter ownership on dividends is greater only at higher level of ownership, where promoters become entrenched with their effective control, and outsiders face the greatest risk of expropriation. We contend that agency and information asymmetry problems are the factors driving our results. We establish this by showing that the nonlinear relation between promoter ownership and dividend payment is more pronounced for standalone firms than group affiliated firms, for firms with more free cash flows and for firms with smaller board and less number of independent directors in the board. Our results are robust to endogeneity concerns and testing the dividend payment decision (to pay or not to pay) using the binary choice logit model.
Hedging Around a CEO Change: Further Evidence from the Oil and Gas Industry
Authors: Iqbal Zahid , Shetty Shekar
Published: November 2023

This study examines hedging activities around hiring of chief executive officer (CEO). Data on the use of derivatives by a sample of oil and gas firms were hand collected from the 10-k filings and compared for several years before and after a CEO change. A regression method was employed to examine if hedging is associated with the CEO change after controlling for the effects of hedging variables. The findings show that net hedging decreased from three years prior to CEO hiring and increased for several years thereafter. The regression results show that hiring of a new CEO explains change in hedging one year after the CEO is hired when interactions among the explanatory variables are considered. This is one of the few studies that examine the relationship between hedging behavior and CEO change.
Environmental, Social, Governance Performance and Negative Performance Feedback: Firm Moderators in a Cross-country Context
Authors: DasGupta Ranjan , Roy Arup
Published: November 2023

In this study, we have examined two specific research questions. First, whether firms around the world with negative performance feedback would resort to more environmental, social, governance [ESG] performance or otherwise. Second, we examine whether firms’ ESG controversies and stakeholder orientation in a cross-country context, with distinctive legal system and ethical behaviour, would motivate them to undertake more ESG performance in such negative performance feedback conditions. Our primary findings show that negative performance feedback of a firm impacts its ESG performance in a strongly negative manner. Furthermore, we prove that both high stakeholder orientation and high ESG controversies significant negatively moderate firms’ ESG inclinations. This holds true irrespective of country-specific legal system and ethical behaviour contexts.
Rapid Changes in Teaching and Learning: The Response of Teachers and Students in Dual Credit Courses to Online Learning During the COVID-19 Pandemic
Authors: Glennie Elizabeth J. , Smith W. Zach
Published: November 2023

In spring 2020, the COVID-19 pandemic forced schools to switch quickly to online learning. Before then, Hawaiʻi had been expanding its dual credit program, in which high school students could take courses that would yield both high school and college credits. These dual credit programs require partnerships between high schools and colleges. RTI International conducted a multi-method analysis to examine the effect of this COVID-19–based transition to online learning on the dual credit, analyzing data from the state longitudinal data system and conducting surveys and focus groups of the University of Hawaiʻi’s instructors, high school coordinators, and high school staff involved with program. From spring 2020 to fall 2020, students took some dual enrollment courses even though offerings and enrollment declined; offerings and enrollment rebounded by spring 2021. The percentage of course-takers earning both high school and college credit remained about the same during this transition. Examining outcomes for student and school subgroups shows that male students struggled more than female students did with enrollment during this transition, and students in rural schools had a steeper decline in the rate of earning both high school and college credits. However, both groups did begin to recover by spring 2021.

Published: November 2023

Red giants play a crucial role in astronomical exploration. However, the current search for these stars heavily relies on spectrum analysis, making it a cumbersome process. In this paper, we propose a novel red giant search approach called CBAMResNets. CBAMResNets enhances feature extraction from images by incorporating the Convolutional Block Attention Module into the ResNets model. To train and validate our model, we utilize accurately labeled stellar image data obtained by combining the Sky Mapper Southern Survey (SMSS) and the Large Sky Area Multi-Object Fiber Spectroscopic Telescope. Our experiments demonstrate that CBAMResNets outperforms other networks such as VGG16 and TPC across most performance metrics and remains competitive with traditional machine-learning methods. Specifically, for stars within the magnitude range of 11–19 in the u band, our model achieves a precision rate of 0.92 and a recall rate of 0.9194. Similarly, for stars within the magnitude range of 11–15 in the u band, the precision rate is 0.92, and the recall rate is 0.9813. Furthermore, we apply CBAMResNets to the SMSS subregion, resulting in the identification of 20,243 potential red giant candidates out of the 304,477 observed stars. We validate the authenticity of these candidates by analyzing their stellar absolute magnitudes and temperatures, estimating a contamination rate of approximately 6.4%. Additionally, we examine the approximate distribution of their metallicity. The catalog containing the identified red giant candidates can be accessed at Zenodo.

PG 1004+130: Hybrid Morphology Source or a Restarted FRII? A uGMRT Polarimetric Investigation
Authors: Ghosh Salmoli , Kharb P. , Baghel J. , Silpa S.
Published: November 2023

We present the polarization image of the hybrid morphology and broad absorption line quasar PG 1004+130 at 694 MHz obtained with the upgraded Giant Metrewave Radio Telescope. We detect linear polarization in this source’s core, jets, and lobes. The visible discontinuity in total intensity between the inner jets and the kiloparsec-scale lobes suggests that the source is restarted. The inferred poloidal magnetic (B-) field structure in the inner jet is consistent with that observed in Fanaroff–Riley (FR) type II sources, as are the B-fields aligned with the lobe edges. Moreover, archival Chandra and XMM-Newton data indicate that PG 1004+130 displays several FRII-jetlike properties in X-rays. We conclude that PG 1004+130 is a restarted quasar, with both episodes of activity being FRII type. The spectral index images show the presence of an inverted spectrum core (α = +0.30 ± 0.01) and a steep spectrum inner jet (α = −0.62 ± 0.06) surrounded by much steeper lobe emission (α ≈ −1.2 ± 0.1), consistent with the suggestion that the lobes are from a previous activity episode. The spectral age difference between the two activity episodes is likely to be small (<1.2 × 107 yr), in comparison to the lobe ages (∼3.3 × 107 yr). The inferred B-fields in the lobes are suggestive of turbulence and the mixing of plasma. This may account for the absence of X-ray cavities around this source, similar to what is observed in M87's radio halo region. The depolarization models reveal that thermal gas of mass ∼(2.4 ± 0.9) × 109
M
⊙ is mixed with the nonthermal plasma in the lobes of PG 1004+130.
Solution to the Conflict between the Estimations of Resolved and Unresolved Galaxy Stellar Mass from the Perspective of JWST
Authors: Song Jie , Fang GuanWen , Lin Zesen , Gu Yizhou , Kong Xu
Published: November 2023

By utilizing the spatially resolved photometry of galaxies at 0.2 < z < 3.0 in the CEERS field, we estimate the resolved and unresolved stellar mass via fitting of the spectral energy distribution (SED) to study the discrepancy between them. We first compare M
* derived from photometry with and without the JWST wavelength coverage and find that M
* can be overestimated by up to 0.2 dex when lacking rest-frame near-infrared (NIR) data. The SED fitting process tends to overestimate both stellar age and dust attenuation in the absence of rest-frame NIR data, consequently leading to a larger observed mass-to-light ratio and hence an elevated M
*. With the inclusion of the JWST NIR photometry, we find no significant disparity between the estimates of resolved and unresolved stellar mass, providing a plausible solution to the conflict between them out to z ∼ 3. Further investigation demonstrates that reliable M
* estimates can be obtained, regardless of whether they are derived from spatially resolved or spatially unresolved photometry, so long as the reddest filter included in the SED fitting has a rest-frame wavelength longer than 10000 Å.
Energetics of a Solar Flare and a Coronal Mass Ejection Generated by a Hot Channel Eruption
Authors: Zhang Qingmin , Teng Weilin , Li Dong , Dai Jun , Zhang Yanjie
Published: November 2023

Hot channels (HCs) are prevalent in the solar corona and play a critical role in driving flares and coronal mass ejections (CMEs). In this paper, we estimate the energy content of an X1.4 eruptive flare with a fast CME generated by an HC eruption on 2011 September 22. Originating from NOAA Active Region 11302, the HC is the most dramatic feature in 131 and 94 Å images observed by the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory (SDO). The flare is simultaneously observed by SDO/AIA, the Reuven Ramaty High-energy Solar Spectroscopic Imager, and the Extreme-ultraviolet Imager on board the “behind” Solar Terrestrial Relations Observatory (STEREO). The CME is simultaneously detected by the white-light coronagraphs of the Large Angle Spectroscopic Coronagraph on board the Solar and Heliospheric Observatory and the COR1 coronagraph on board the behind STEREO. Using multiwavelength and multiview observations of the eruption, various energy components of the HC, flare, and CME are calculated. The thermal and kinetic energies of the HC are (1.77 ± 0.61) × 1030 erg and (2.90 ± 0.79) × 1030 erg, respectively. The peak thermal energy of the flare and total radiative loss of the soft X-ray–emitting plasma are (1.63 ± 0.04) × 1031 erg and (1.03–1.31) × 1031 erg, respectively. The ratio between the thermal energies of the HC and flare is 0.11 ± 0.03, suggesting that the thermal energy of the HC is not negligible. The kinetic and potential energies of the CME are (3.43 ± 0.94) × 1031 erg and (2.66 ± 0.49) × 1030 erg, yielding a total energy of (3.69 ± 0.98) × 1031 erg for the CME. Continuous heating of the HC is required to balance the rapid cooling by heat conduction, which probably originates from intermittent magnetic reconnection at the flare current sheet. Our investigation may provide insight into the buildup, release, and conversion of energies in large-scale solar eruptions.

Predictive Modeling of Total Operating Room Time for Laparoscopic Cholecystectomy Using Preoperatively Known Indicators to Guide Accurate Surgical Scheduling in a Critical Access Hospital
Authors: Prier Todd , Yale-Suda Kelly , Westover Hailey , Corey Ryan
Published: November 2023

The financial margin of rural and critical access hospitals highly depends on their surgical volume. An efficient operating room is necessary to maximize profit and minimize financial loss. OR utilization is a crucial OR efficiency metric requiring accurate case duration estimates. The patient's age, ASA, BMI, Malampati score, previous surgery, the planned surgery, the surgeon, the assistant's level of experience, and the severity of the patient's disease are also associated with operative duration. Although complex machine learning models are accurate in operative prediction, they are not always available in resource-limited hospitals. Laparoscopic cholecystectomy (LC) is one of the most common surgical procedures performed and is one of the few procedures performed at critical access and rural hospitals. The accurate estimation of the operative duration of LC is essential for efficient OR utilization. We hypothesize that a multivariate linear regression prediction model can be constructed from a set of preoperatively known, easily collected variables to maximize OR utilization and improve operative scheduling accuracy for LC. We further hypothesize that this model can be implemented in resource-limited environments, such as critical access hospitals.
New fossil stoneflies (Plecoptera: Arctoperlaria) from Australia testify ancient dispersal across Pangea
Authors: Sroka Pavel , Prokop Jakub
Published: November 2023

The stonefly suborders Arctoperlaria and Antarctoperlaria reflect the current division of the diversity of this insect order between the Northern and Southern Hemispheres. However, there are several exceptions to this pattern, the most notable being the family Notonemouridae, which is phylogenetically deeply subordinate within the northern Arctoperlaria, but distributed in South Africa, South America, and Australia. Various hypotheses have been proposed regarding the circumstances of their dispersal to the south. Some estimated their origin as relatively recent, with long-distance dispersal to the southern continents in the Late Cretaceous or early Paleogene. On the other hand, fossils of Notonemouridae have been dated to the Middle Jurassic, proving the lineage is very ancient. However, all known notonemourid fossils originate from Asia and the timing of their dispersal to the south cannot be precisely estimated. Here we report new fossil stoneflies from the Late Jurassic Talbragar Fish Beds, Australia, described as Talbragaria australisgen. et sp. nov. and attributed to Notonemouridae. This finding represents the first fossil evidence of the northern suborder Arctoperlaria in the Southern Hemisphere, and confirms the north-to-south dispersal of Notonemouridae across Pangea prior to the continental break-up.

Published: November 2023

Our aim of this work is to present a review of solar photovoltaic (PV) systems and technologies. The principle of functioning of a PV system and its major components are first discussed. The types of PV systems are described regarding the connections and characteristics of each type. PV technology generations are demonstrated, including the types, properties, advantages and barriers of each generation. It was revealed that the first generation is the oldest among the three PV generations and the most commonly utilized due to its high efficiency in spite the high cost and complex fabrication process of silicon; the second generation is characterized by its low efficiency and cost and flexibility compared to other generations; and the third generation is not commercially proven yet in spite the fact that it has the highest efficiency and relatively low cost, its raw materials are easy to find and its fabrication process is easier than the other generations. It was shown that the target of all the conducted studies is to study the PV technology to enhance its performance and optimize the benefit from solar energy by reducing conventional energy dependence, mitigating CO2 emissions and promote the economic performance.

Published: November 2023

The article aimed to develop an accurate approximation of the fractional derivative with a non-singular kernel (the Rabotnov fractional-exponential formula), and show how to use it to solve numerically the blood ethanol concentration system. This model can be represented by a system of fractional differential equations. First, we created a formula for the fractional derivative of a polynomial function $ t^{p} $ using the Rabotnov exponential kernel. We used the shifted Vieta-Lucas polynomials as basis functions on the spectral collocation method in this work. By solving the specified model, this technique generates a system of algebraic equations. We evaluated the absolute and relative errors to estimate the accuracy and efficiency of the given procedure. The results point to the technique's potential as a tool for numerically treating these models.
Modeling and analysis of a stochastic giving-up-smoking model with quit smoking duration
Authors: Guo Yajuan , Liu Zijian , Tan Yuanshun , Liu Yawei
Published: November 2023

Smoking has gradually become a very common behavior, and the related situation in different groups also presents different forms. Due to the differences of individual smoking cessation time and the interference of environmental factors in the spread of smoking behavior, we establish a stochastic giving up smoking model with quit-smoking duration. We also consider the saturated incidence rate. The total population is composed of potential smokers, smokers, quitters and removed. By using Itô's formula and constructing appropriate Lyapunov functions, we first ensure the existence of a unique global positive solution of the stochastic model. In addition, a threshold condition for extinction and permanence of smoking behavior is deduced. If the intensity of white noise is small, and $ \widetilde{\mathcal{R}}_0 < 1 $, smokers will eventually become extinct. If $ \widetilde{\mathcal{R}}_0 > 1 $, smoking will last. Then, the sufficient condition for the existence of a unique stationary distribution of the smoking phenomenon is studied as $ R_0^s > 1 $. Finally, conclusions are explained by numerical simulations.
Machine learning-based quantitative trading strategies across different time intervals in the American market
Authors: Wang Yimeng , Yan Keyue
Published: November 2023

Stocks are the most common financial investment products and attract many investors around the world. However, stock price volatility is usually uncontrollable and unpredictable for the individual investor. This research aims to apply different machine learning models to capture the stock price trends from the perspective of individual investors. We consider six traditional machine learning models for prediction: decision tree, support vector machine, bootstrap aggregating, random forest, adaptive boosting, and categorical boosting. Moreover, we propose a framework that uses regression models to obtain predicted values of different moving average changes and converts them into classification problems to generate final predictive results. With this method, we achieve the best average accuracy of 0.9031 from the 20-day change of moving average based on the support vector machine model. Furthermore, we conduct simulation trading experiments to evaluate the performance of this predictive framework and obtain the highest average annualized rate of return of 29.57%.
Does Blockchain and Internet of Things (BCoT) Help in Managing Customer Data?
Authors: Awini Gideon , Akeji Alhassan Abdul-Rasheed Alolo , Majeed Mohammed , Mensah Kobby
Published: November 2023

The internet of things (IoT) is transforming the established sector into a smart sector with “data-driven decision making.” IoT's inherent characteristics, however, provide a variety of difficulties, including decentralization, weak interoperability, privacy concerns, and security flaws. Blockchain technology offers possibilities for overcoming IoT issues. In the realm of the internet of things, the introduction of blockchain has recently sparked a lot of attention. The existing blockchain system, however, has a number of non-trivial issues that prohibit it from serving as a general foundation for extensive IoT services and applications. This study provides a comprehensive analysis of BCoT and explores the lessons learned from this novel paradigm. In particular, the authors first briefly describe the IoT and its difficulties. Then, they provide an introduction to blockchain technology. Next, they focused on describing the IoT and blockchain convergence and outlining the BCoT architecture proposal. They talk about BCoT's industrial uses and the problems of adopting “blockchain for 5G beyond IoT.”

Based on a conceptual discussion, this chapter focused on current consumer behavior, with a special emphasis on its relationship with sustainability, and on the recent sustainable practices of companies. Through the analysis of these two pillars, this narrative review aimed to frame sustainability and emphasize the greenwashing processes that take place in this context. To this end, some reasons why sustainability has been a major subject of debate in recent decades and also evidence on consumer behavior about this discussion were pointed out. The role of companies was also outlined – through corporate social responsibility practices – bridging the issue of greenwashing. As a negative aspect associated with sustainability, greenwashing was observed in depth, with a special focus on the digital environment, and in the context of marketing and influence.

Authors: Ouyang Jinhua
Published: November 2023

The overload of sports information resources has greatly increased the difficulty for users to choose resources. To solve this problem, this paper proposes a sports digital teaching resource recommendation model based on collaborative filtering algorithm to achieve the optimization of sports teaching mode in the context of big data and multimedia. Based on the detailed analysis of the teaching resource construction platform, the improved algorithm is applied to the teaching resource recommendation platform, and the algorithm effect is verified based on the collected data. The experimental data shows that the error of this method is significantly better than ID3 algorithm, the error is reduced by 26.55%, and the recall rate is 95.72%, which is 12.76% higher than ID3 algorithm. The introduction of personalized recommendation technology into the utilization of sports information resources can improve the efficiency and accuracy of users' access to resources and strengthen the adaptability to the continuous deconstruction and new integration of the higher education system.

Published: November 2023

Cold agglutinin disease (CAD) is a rare autoimmune hemolytic anemia associated with autoantibodies that react mainly in the cold. CAD can interfere with immunohematology tests. We report two cases of CAD presented initially as blood grouping discrepancy leading us to further workup. Case I was a 61-year-old female with symptoms of weakness, bone pain, and difficulty breathing with laboratory findings of high cold agglutinin titers of 1:1024. Bone marrow aspirate revealed a mixture of >30% plasma cell and plasma blast. Bone marrow biopsy revealed an interstitial, focal, and nodular pattern of involvement by plasma cells, leading to the diagnosis of plasma cell dyscrasias. Case II analyzed was benign CAD with cold agglutinin titers of 1:64, with no other abnormality. Both patients were managed successfully. We report serological and clinical findings of two CAD cases with similar serological findings but different clinical outcomes.

Context

Post-coronavirus disease 2019 (COVID-19) disease patients are immunocompromised, especially those who have a history of hospitalization during the COVID time and steroid use during hospitalization. Such patients are very susceptible to opportunistic infections and must be assessed proactively.

Patients and methods

This was a cross-sectional study on 125 post-COVID-19-positive patients 28 days after being COVID negative confirmed by an RT-PCR test. Sputum/bronchoalveolar lavage samples were taken for analysis.

Statistical analysis used

SPSS, version 20.0 was used for the analysis. A P value less than 0.05 was considered statistically significant.

Results

Out of 119 sputum samples assessed, 15 were AFB positive, and Mycobacterium tuberculosis (MTB) was detected in 16 patients by the GeneXpert assay, out of which 15 were sensitive to rifampicin and one was resistant. Bronchoalveolar lavage was performed in nine patients where two were found AFB-positive, and MTB was detected in two patients by the GeneXpert, out of which one was rifampicin sensitive and one was rifampicin resistant.

Conclusions

A significant portion of the world population has latent tuberculosis (TB) infection, and the COVID-19 disease may have led to an increase in the incidence of active TB. A proactive approach is needed for the diagnosis of TB and to control the spread of TB.
Study of COVID-19 confirmed cases in isolation hospital in (Hurghada General Hospital)

Background and purpose

The WHO declared the coronavirus disease 2019 (COVID-19) outbreak a global public health emergency on January 30, 2020, and the word ‘pandemic’ was first used to describe the disease’s global spread in March of that year. Chronic lung disease (19.2% was the most common co-occurring condition with COVID-19), at 20.8%, followed by chronic kidney disease (20.8%), and then cardiovascular disease (60.9%). This research aimed to assess the prognosis of COVID-19-confirmed cases receiving isolation care at Hurghada General Hospital.

Study design

An observational study that was retrospective and cross-sectional.

Setting

Isolation department in Hurghada General Hospital.

Patients

We included 122 patients with COVID-19 infection, and classified them into two independent groups: the improvement group (93 patients), and the morbidity (complication) and mortality group (29 patients).

Methods

Clinical data (COVID-19 symptoms and vital signs), laboratory data (complete blood count, C-reactive protein, ferritin level in the blood, hepatic and renal functions tests, coagulation profile, and level of D-dimer), radiological data (computed tomography of the chest), and drug and antibiotic data were collected from all patients. The following parameters were assessed in each patient: length of hospital stay, ICU admission, mechanical ventilation, morbidity (complication), mortality, improvement, and discharge.

Results

Patients’ average age in the sample was 55 ± 16.3 years. Regarding patients’ respective sexes, 55.7% of patients were females, while 44.3% were males. Regarding the final outcome data, the average length of hospital stay was 9.2 ± 6.2 days, with 33.6% of patients having ICU admission, 9% were ventilated, morbidity(16.4%) (complication) (4.9% psychological and neurological disorders, 3.3% post-COVID oxygen-dependent therapy, 8.2% renal impairment), and mortality (7.4%), while 76.2% had improved and discharged. Logistic regression results demonstrated that the increase in age, BMI, lactate dehydrogenase, D-dimer, computed tomography chest affection, and COVID-19 severity (according to clinical, laboratory and radiological data); added to the risk of needing to be admitted to a hospital’s ICU on its own (P<0.05, respectively). Decreases in oxygen saturation, urea, and prothrombin time were found to independently increase the likelihood of ICU admission in a logistic regression analysis (P<0.05).

Conclusion

We conclude that age and comorbidities such as diabetes, hypertension, ischemic heart disease, and lung fibrosis are strongly related to adverse outcomes in COVID-19 patients admitted to the Hurghada Isolation Hospital. It was also more likely that those patients would develop acute respiratory distress syndrome or severe pneumonia.

Strict treatment protocol and isolation lead to better outcomes.
