Emotions and Topics Expressed on Twitter During the COVID-19 Pandemic in the United Kingdom: Comparative Geolocation and Text Mining Analysis
Authors: Alhuzali Hassan , Zhang Tianlin , Ananiadou Sophia 
Published: September 2022

Background
In recent years, the COVID-19 pandemic has brought great changes to public health, society, and the economy. Social media provide a platform for people to discuss health concerns, living conditions, and policies during the epidemic, allowing policymakers to use this content to analyze the public emotions and attitudes for decision-making.

Objective
The aim of this study was to use deep learning–based methods to understand public emotions on topics related to the COVID-19 pandemic in the United Kingdom through a comparative geolocation and text mining analysis on Twitter.

Methods
Over 500,000 tweets related to COVID-19 from 48 different cities in the United Kingdom were extracted, with the data covering the period of the last 2 years (from February 2020 to November 2021). We leveraged three advanced deep learning–based models for topic modeling to geospatially analyze the sentiment, emotion, and topics of tweets in the United Kingdom: SenticNet 6 for sentiment analysis, SpanEmo for emotion recognition, and combined topic modeling (CTM).

Results
We observed a significant change in the number of tweets as the epidemiological situation and vaccination situation shifted over the 2 years. There was a sharp increase in the number of tweets from January 2020 to February 2020 due to the outbreak of COVID-19 in the United Kingdom. Then, the number of tweets gradually declined as of February 2020. Moreover, with identification of the COVID-19 Omicron variant in the United Kingdom in November 2021, the number of tweets grew again. Our findings reveal people’s attitudes and emotions toward topics related to COVID-19. For sentiment, approximately 60% of tweets were positive, 20% were neutral, and 20% were negative. For emotion, people tended to express highly positive emotions in the beginning of 2020, while expressing highly negative emotions over time toward the end of 2021. The topics also changed during the pandemic.

Conclusions
Through large-scale text mining of Twitter, our study found meaningful differences in public emotions and topics regarding the COVID-19 pandemic among different UK cities. Furthermore, efficient location-based and time-based comparative analysis can be used to track people’s thoughts and feelings, and to understand their behaviors. Based on our analysis, positive attitudes were common during the pandemic; optimism and anticipation were the dominant emotions. With the outbreak and epidemiological change, the government developed control measures and vaccination policies, and the topics also shifted over time. Overall, the proportion and expressions of emojis, sentiments, emotions, and topics varied geographically and temporally. Therefore, our approach of exploring public emotions and topics on the pandemic from Twitter can potentially lead to informing how public policies are received in a particular geographical area.

Wikipedia es el mayor recurso educativo abierto (REA) del mundo: una enciclopedia en línea gratuita que anima a todas las personas a contribuir en su construcción. Aunque es visitada con regularidad tanto por docentes como estudiantes, sigue infrautilizada como recurso pedagógico. En el 2020, se lanzó el programa "Leamos Wikipedia en el Aula" (Reading Wikipedia in the Classroom, en inglés): un programa de desarrollo profesional para docentes de nivel secundario en el uso de Wikipedia como herramienta pedagógica para promover habilidades de alfabetización mediática e informacional (AMI). El programa gratuito se desarrolló en tres países: Bolivia, Marruecos y Filipinas, como una experiencia de aprendizaje en línea. Se demostró que cuando los docentes se acercan a Wikipedia de forma crítica, se apropian de este recurso digital y aumenta el valor que le asignan. Al reflexionar críticamente sobre las características de Wikipedia y los procesos de participación a través de la lente de su propia práctica docente, identifican herramientas y estrategias para guiar a sus estudiantes en el uso de este REA.

<p> </p>
<p><strong>Objective</strong> Data on real-world burden of herpes zoster (HZ) in adults with type 2 diabetes mellitus (T2D) in the U.S. are limited<strong>.</strong> We assessed HZ in patients with and without T2D and measured the impact of HZ on healthcare resource use (HCRU) and costs.</p>
<p><strong>Research design and methods</strong> A retrospective cohort analysis using U.S. commercial claims data (sourced from claims incurred between January 1, 2012 and July 31, 2018). HZ incidence rates/1,000 person-years [PY] were calculated in patients with/without T2D; HZ risk was evaluated using Poisson regression to generate adjusted incidence rate ratios (aIRRs). T2D patients with HZ were propensity score matched to patients with T2D only, and to patients with HZ without T2D. HCRU and costs were compared across cohorts during a 1-year follow-up period. Cox proportional hazards analyses evaluated factors associated with HZ-related complications. </p>
<p><strong>Results</strong> Crude HZ incidence rates in patients with and without T2D were 9.8/1,000 PY and 2.6/1,000 PY respectively. T2D patients were almost twice as likely to be diagnosed with HZ (aIRR, 1.84 [95% CI: 1.82–1.85]). HZ was associated with increased HCRU and healthcare costs. At 12-months, unadjusted incremental all-cause healthcare costs for T2D patients with HZ versus T2D patients without HZ were $5,216; unadjusted incremental HZ-related healthcare costs for T2D patients with HZ versus patients with HZ without T2D were $2,726. Age was the most important predictor for HZ-related complications.</p>
<p><strong>Conclusions</strong> Given the increased risk of HZ and HCRU and cost burden in T2D patients, HZ prevention in T2D patients may be beneficial. </p>

SUMMARY

Objective
This study aimed to evaluate the external and internal adaptations of cervical restorations using different restorative techniques.

Methods
Forty extracted and intact human premolars received standardized cervical preparations to simulate non-carious cervical lesions. The teeth were randomly divided into four groups (n=10) according to the restorative technique: D, direct composite restoration without a base (Palfique LX5, Tokuyama Dental Corp Inc, Tokyo, Japan); DB, direct composite restoration with a flowable composite liner (Estelite Flow Quick -High Flow, Tokuyama Dental Corp Inc); DI, direct–indirect composite restoration bonded with flowable composite; and I, indirect restoration bonded with flowable composite. Marginal adaptation of the restorations was observed in different segments of the margins using a scanning electron microscope. Analyses of internal adaptation were performed using micro-computed tomography. The Kruskal–Wallis and Mann–Whitney tests were used for statistical analysis of the data (α=5%).

Results
No significant differences were found in the marginal adaptation of the groups (p&gt;0.05), although a significantly higher percentage of continuous margin was found in the proximal segment than in the cervical segment (p&lt;0.05). No significant differences were detected between the groups in terms of internal adaptation (p&gt;0.05).

Conclusion
All the restorative techniques evaluated for the restoration of cervical lesions performed similarly in terms of marginal and internal adaptation.
Determinants of Banks Profitability: An Evidence from GCC Countries
Authors: Khan Shoaib 
Published: September 2022

Abstract
The research objective of the study is to investigate the determinants of profitability of banks’ operating in GCC (Gulf Cooperation Council) countries. The existing studies highlight the banks’ internal attributes and external factors that significantly influence profitability. The unbalanced panel data of 59 banks from the Bank scope database operating in six countries of GCC is used. Profitability is measured as return on assets (ROA) and return on equity (ROE) that have been used as dependent variables. Pooled OLS, fixed and random effects estimations are employed to explore the effect of explanatory variables internal factors, i.e. bank size, capital adequacy, asset quality, deposits ratio, asset management, operating efficiency and financial risk, and external factors, namely macroeconomic variables, GDP growth rate and inflation rate on dependent variables. Bank size and GDP growth have a significant and positive association with ROA. While Bank size and asset management have significant and positive impact, capital adequacy, financial risk, operating efficiency, and asset quality have a negative and significant impact on ROE. Fixed effects results are used for interpretation based on the Hausman test.
Delta variant: Partially sensitive to vaccination, but still worth global attention

Published: September 2022

Abstract
The pandemic coronavirus disease 2019 (COVID-19) has rapidly spread to all countries worldwide. The emergence of its variants has exacerbated this problem. To date, many variants have been identified across the viral genome; the variants of concern are the focus of attention due to their higher transmissibility and resistance to vaccines, especially the delta variant. The delta variant has become the dominant severe acute respiratory syndrome novel coronavirus (SARS-CoV-2) variant worldwide, causing severe panic as it is highly infectious. A better understanding of these variants may help in the development of possible treatments and save more lives. In this study, we summarize the characteristics of the variants of concern. More importantly, we summarize the results of previous studies on the delta variant. The delta variant has a high transmissibility rate and increases the risk of hospitalization and death. However, it is partially sensitive to vaccines. In addition, nonpharmaceutical interventions are valuable during epidemics. These interventions can be used against the delta variant, but managing this variant should still be taken seriously.

Abstract

Background and purpose: Today’s dynamic environment is increasingly pressuring public organizations to be simultaneously flexible and efficient. The purpose of this study was to examine the mediating role of organizational ambidexterity in the relationship between psychological capital and the perfor-mance of public organizations that have bureaucratic limitations to their activity and are not as competitive as the private sector.

Methods: A questionnaire was developed and distributed among the employees of Management and Planning Organizations in 31 provinces in Iran, and a total of 373 questionnaires were returned. The data was analysed using CFA to validate the measures, and then the mediating effects of organi-zational ambidexterity was tested.

Results: The results indicated the significant relationship between psychological capital and organizational performance (B=0.55) and the positive mediation effect of organizational ambidexterity on this relationship (0.333).

Conclusion: The findings can help managers of public organizations to enhance their organizational performance by strengthening psychological capital and ambidexterity.

The OBJECTIVE was to replenish and systematize the ideas about the achievements of Soviet scientists in the field of combustiology based on the analysis of the publication array on the problem of «Thermal injury» for the period 1920-1930s.METHODS AND MATERIALS. A structural and substantive analysis of the array of publications on the problem of treating thermal injuries, revealed as a result of attracting a wide range of bibliographic resources, such as catalogs of leading libraries, current and retrospective indexes, and databases, has been carried out. The inclusion of new sources of information in the research space made it possible to discover and for the first time to introduce into scientific circulation a large number of scientific works that require a new understanding of the achievements of domestic doctors in the field of treating burns during this period, differently prioritizing, assessing the personalization of the contribution of scientists and research teams. The bibliographic indexes of Russian traumatology for 1924-1940, catalogs of the largest universal and branch (medical) libraries of St. Petersburg and Moscow have been investigated.RESULTS. We found out that in the period from 1924-1940, 579 works on various aspects of thermal injury were published on the pages of the Soviet medical press, including materials from the speeches of researchers at scientific conferences and meetings of medical societies in various cities of our country.CONCLUSION. The obtained results made it possible to restore and clarify many undeservedly forgotten facts of the history of Russian combustiology.

Published: September 2022

The OBJECTIVE was to demonstrate an original minimally invasive way to restore the continuity of the lobar duct after its complete intersection.METHODS AND MATERIALS. The study included 3 patients aged 38, 56 and 69 years who underwent laparoscopic cholecystectomy for cholelithiasis, cholecystolithiasis in various medical institutions of the city. In all patients, the intersection of the right lobar duct with the formation of an external biliary fistula in the postoperative period was revealed. RESULTS. All patients underwent recanalization of the crossed duct on the first attempt. After the fistula was formed on the frame drainage, the flow of bile through the external biliary fistula gradually regressed: in one patient, bile leakage from the abdominal cavity stopped after two days, in two patients after a week. Drainages from the subhepatic space were removed in all patients on the 9th day after restoration of the continuity of the intersect duct. Kehr's drainage was removed after 12 days in one patient, after 21 days in another. Retrograde external drainage was removed from the third patient on the 5th day after restoration of the patency of the duct on the frame drainage. After control X-ray images, the external-internal frame drainages were blocked for patients on the 5-10th day after the operation. There were no leaks of contrast agent through the restored section of the duct.CONCLUSION. The developed method of minimally invasive restoration of continuity and patency of the intersected and excised hepatic duct is an alternative to the traditional reconstructive biliodigestive bypass surgery. Long-term frame drainage of the bile duct in the area of damage allows forming sufficient diameter for an unobstructed passage of bile.

Background:
Early neurocritical care aims to ameliorate secondary traumatic brain injury (TBI) and improve neural salvage. Increased engagement of neurosurgeons in neurocritical care is warranted as daily briefings between the intensivist and the neurosurgeon are considered a quality indicator for TBI care. Hence, neurosurgeons should be aware of the latest evidence in the neurocritical care of severe TBI (sTBI).

Methods:
We conducted a narrative literature review of bibliographic databases (PubMed and Scopus) to examine recent research of sTBI.

Results:
This review has several take-away messages. The concept of critical neuroworsening and its possible causes is discussed. Static thresholds of intracranial pressure (ICP) and cerebral perfusion pressure may not be optimal for all patients. The use of dynamic cerebrovascular reactivity indices such as the pressure reactivity index can facilitate individualized treatment decisions. The use of ICP monitoring to tailor treatment of intracranial hypertension (IHT) is not routinely feasible. Different guidelines have been formulated for different scenarios. Accordingly, we propose an integrated algorithm for ICP management in sTBI patients in different resource settings. Although hyperosmolar therapy and decompressive craniectomy are standard treatments for IHT, there is a lack high-quality evidence on how to use them. A discussion of the advantages and disadvantages of invasive ICP monitoring is included in the study. Addition of beta-blocker, anti-seizure, and anticoagulant medications to standardized management protocols (SMPs) should be considered with careful patient selection.

Conclusion:
Despite consolidated research efforts in the refinement of SMPs, there are still many unanswered questions and novel research opportunities for sTBI care.
ОСОБЕННОСТЬ И ПРЕИМУЩЕСТВА ИННОВАЦИОННОЙ ПАРАДИГМЫ БЮДЖЕТНО-НАЛОГОВОЙ СИСТЕМЫ
Authors: Павлов Вячеслав Иванович , Зоидов Хуршеджон Кобилджонович 
Published: September 2022

Цель работы. В статье обосновывается особенность новой бюджетно-налоговой системы как приоритета развития электроэнергетики и преимущества перед традиционной бюджетно-налоговой системой, особенно в период существенного ограничения международной торговли из-за широкомасштабных санкций США, стран ЕС и других стран, поддерживающих политику США. Метод и методология работы. В процессе исследования использованы методы эволюционно-институциональной теории, эконометрического моделирования и аналитической оценки. Результаты и выводы. Внедрение инновационной парадигмы бюджетно-налоговой системы можно отнести к импортозамещению, так как действующая в настоящее время налоговая система заимствована из зарубежных стран с российской спецификой НДФЛ со ставкой доходов 13 % и дополнительной ставкой 2 % с превышающих 5 млн рублей в год морально устарела. Инновационная парадигма бюджетно-налоговой системы, используя минимальное количество исходной информации и возможности использования инструментов государственной казначейской системы и цифровизации, ликвидирует базу для коррупционных структур и наполнений бюджетов всех уровней исполнительной власти в объемах, необходимых для выполнения ими своих функций. Область применения результатов. Результаты исследования могут быть использованы органами власти России для ликвидации существующих проблем в области обеспечения экономической безопасности, при реализации структурных реформ, реформы системы государственных финансов, изменении налоговой политики.

Published: September 2022

Background
Salmonellosis remains the second most common zoonosis in the European Union despite a long-term decreasing trend. However, this trend has been reported to have stagnated in recent years, particularly for Salmonella enterica serotype Enteritidis (SE).

Aim
To describe temporal changes in the incidence of SE human infections, and in its associated factors between 2006 and 2019. In addition, we aim to determine which factors influenced the stagnated trend seen in recent years.

Methods
Data on culture-confirmed SE human infections from national surveillance registries in the Netherlands and Belgium between 2006 and 2019 were analysed using multivariable negative-binomial regression models with restricted cubic splines.

Results
SE incidence was significantly higher in summer and autumn than winter, in persons aged 0–4 years and 5–14 years than in persons ≥ 60 years, and increased with increasing proportions of travel-related and resistant SE infections. SE incidence decreased significantly in both countries until 2015, followed by an increasing trend, which was particularly pronounced in the Netherlands. Potential SE outbreaks in both countries and invasive infections in the Netherlands also increased after 2015.

Conclusion
The increase in potential outbreaks and invasive infections since 2015 may partially explain the observed reversal of the decreasing trend. While these results provide insights into the possible causes of this trend reversal, attention should also be given to factors known to influence SE epidemiology at primary (animal) production and pathogen genomic levels.
Early Complications after Limb Salvage Procedures: Prospective Cross Sectional Study
Authors: Ali Ziad , Saeed Javeria , Umer Masood 
Published: September 2022

ABSTRACT

Introduction:
Sarcomas are tumors that are mesenchymal in origin involving bone and soft tissues occurring in all age groups. Giant cell tumor, although benign, is locally aggressive and can also destroy the bone. Amputation was once considered primary treatment but now with advancements in diagnostic imaging modalities, surgical procedures and adjuvant therapies, limb salvage surgeries have become the preferred treatment modality.
The primary objective of our study was to determine the incidence of early complications occurring within the first thirty days in patients who underwent limb salvage surgery at our hospital. The secondary objective was to assess the association of these complications with patient-related factors, surgical modality, tumor characteristics and neoadjuvant therapy.

Methodology:
All the patients with bone or soft tissue sarcoma and aggressive giant cell tumors of the extremities who underwent wide excision and limb salvage surgery from February 2020 to December 2021 were included in this study. Data were collected prospectively on follow-up visits in the clinic for one month. Data were compiled and analyzed using SPSS version 22. A p-value of <0.05 was considered significant throughout the study.

Results:
A total of 60 patients were included in this study. The mean age of the patients was 39.90 years. Bone and soft tissue tumors were found in 35 and 25 patients respectively. A total of 13 patients experienced postoperative complications within 30 days of surgery. The association of these postoperative complications with gender distribution, prior comorbid conditions, type of tumor, anatomical location of the tumor and neoadjuvant therapy was found to be statistically insignificant.

Conclusion:
The most frequently occurring postoperative complications are wound-related and the incidence of these complications is independent of the proposed risk factors.
