Published: October 2024

Background: Genetic variation of SARS-CoV-2 remains a public health challenge worldwide because of it influences the pathogenicity and transmissibility of the virus. Aims: To determine the genomic mutations of SARS-CoV-2 isolated in Egypt. Methods: This was an in silico cross-sectional study of 200 SARS-CoV-2 variants of concern, which were retrieved from the National Centre for Biotechnology Information on 11 January 2021 and aligned with the original Wuhan strain (NC_045512). Nucleotide basic local alignment search tool (BLASTN) was used to identify the nucleotide variations. Corresponding proteins were identified using protein basic local alignment search tool (BLASTP). A phylogenetic tree was constructed to study the evolutionary relationships using the neighbour-joining method. Results: The variants of concern belonged to 26 species and there were 4 non-classified variants. All variants of concern showed 99.47–99.98% homology with the original Wuhan strain and demonstrated up to 60 mutations per variant. There were 1101 mutations identified among the variants of concern, with 458 synonymous and 583 nonsynonymous mutations. Specific mutations that were characteristically present in various SARS-CoV-2 lineages were identified, showing the microevolutionary genetic variations. Conclusion: This study showed vast genetic variations of the Egyptian SARS-CoV-2 with characteristic mutations for the A, B and C lineages. The study contributes to a better understanding of the epidemiological and demographic variations of COVID-19 in Egypt based on SARS-CoV-2 genomic evolution and supports further investigation of SARS-CoV-2 contextbased vaccine development and preventive measures.

Background: Snakebite envenomation remains a significant public health concern in Asir Province of Saudi Arabia. Aim: To characterize snake species and the clinical presentation, outcome and management of snakebite cases admitted to 4 major hospitals in Asir Province, Saudi Arabia. Methods: This retrospective study reviewed medical records of paediatric and adult snakebite cases admitted to 4 regional hospitals in Saudi Arabia between January 2000 and December 2021 using search terms “snakebite”, “cobra”, “polyvalent antivenin”, “antivenom”, “compartment syndrome”, and “fasciotomy”. The data were analysed using R software version 4.2. Results: Sixty-nine patients were identified, of whom 30 (43.5%) were children aged <18 years. Severe local or systemic manifestations occurred in 33 patients (47.8%) while compartment syndrome was suspected in 14 patients (20.3%), requiring fasciotomy in 11 (15.9%). The systemic manifestations included neurotoxicity (13 patients; 18.8%), coagulopathy (31 patients; 44.9%), rhabdomyolysis with creatine phosphokinase >1000 U/L (8 patients; 11.6%), and acute kidney injury (4 patients; 5.8%), with 2 progressing to end-stage renal disease. Three patients (4.5%) died. A majority (94%) received initial 5-vial antivenom dose, with 39% requiring additional doses. Antivenom-related adverse reactions were mild and transient in 6 patients (9%). Blood products and antibiotics were used in 30% and 67% of cases, respectively. Anticholinesterase therapy was administered to 3 patients (4.3%). Conclusion: Snakebites pose a significant public health threat in Asir Province of Saudi Arabia. Antivenom, in addition to supportive care, remains the cornerstone of therapy, however, to optimize patient outcomes, our study highlights the need for a more comprehensive approach to management, as well as vigilant monitoring with prompt recognition and interventions.
DEVELOPMENT OF A CORPORATE EDUCATIONAL INFORMATION SYSTEM WITH THE HELP OF MACHINE LEARNING METHODS AND METHODS OF ENSURING INFORMATION SECURITY
Authors: Ananchenko Oleksiy
Published: October 2024

The article presents the concept and technical aspects of the development of a corporate educational information system using machine learning methods and modern approaches to ensuring information security. The proposed solution is aimed at educational institutions and provides adaptive management of the educational process, optimization of resources and increased information security. The main emphasis is on the development of the system architecture, which includes the efficient placement of servers, the use of containerization technology, system monitoring, version control, and the application of security protocols to protect data and the system as a whole. The use of two servers is proposed: one for basic computing tasks, data storage and support of basic services, and the other for backup, monitoring and protection against unauthorized access. To increase the flexibility and scalability of the system, Docker containerization technology is used, which allows isolating processes and simplifies integration with cloud services. An important component is the integration of external monitoring, which provides control over the availability of services in real time. Emphasis is also placed on the use of reinforced firewalls and backup Internet connections to increase the system's resistance to cyber threats and cyber attacks. Functionality of the system includes an intuitive interface with a number of interactive widgets, such as information about recently registered courses, uploading learning materials, an integrated calendar, displaying performance graphs and task lists. Users can quickly receive information about their progress and plan the next steps in the educational process. An important decision was to abandon the creation of our own corporate chat in favor of implementing ready-made solutions with a high level of security and support for teamwork. This allows you to significantly optimize the use of resources and focus on the development of the main functions of the system. In addition, the use of version control systems for effective project management is proposed, which allows isolating different stages of development and minimizing the risk of errors. The proposed concept of the corporate educational information system provides a comprehensive approach to the management of the educational process taking into account the requirements of modern technologies, increases the effectiveness of education and guarantees a high level of data security.

A idade materna tem sido amplamente reconhecida como um fator determinante na saúde materno-fetal, com
repercussões importantes tanto para a mãe quanto para o feto, é fundamental analisar como a idade materna
influencia a saúde materno-fetal, considerando os impactos que o envelhecimento materno e a gravidez precoce
podem ter nos desfechos obstétricos e neonatais. Objetivo: Analisar o impacto da idade materna na saúde da
mãe e do feto em gravidez de alto risco, destacando complicações potenciais e a importância do acompanhamento
pré-natal. Metodologia: A revisão foi construída a partir de artigos extraídos de bases de dados reconhecidas,
como a Biblioteca Virtual em Saúde (BVS), Scientific Electronic Library Online (SciELO), Caderno da Medicina
- UNIFESO, PERIÓDICOS CAPES, e o Sistema Regional de Información en línea para Revistas Científicas de
América Latina, el Caribe, España y Portugal (LatinDEX), foram utilizados descritores “Complicações da
Gravidez”, “Idade Materna”, “Gestação”, “Gravidez de Alto Risco” e “Saúde Materno-Infantil”. Combinados
com operadores booleanos “AND” e “OR”. Resultados e Discussões: Neste estudo foi possível observar que as
gestantes em idade materna avançada apresentaram diferentes comportamentos e pensamentos a respeito desse
cenário como o medo dos riscos oferecidos a elas e ao feto, a surpresa, pois não sabiam da possibilidade de
engravidar em idade avançada. Além dos fatores biológicos, os aspectos emocionais também são impactados
pela idade materna. Mulheres em idade avançada, em muitos casos, se sentem emocionalmente mais preparadas
para a maternidade, mas enfrentam maiores dificuldades físicas durante a gestação, que gera uma combinação
de confiança e apreensão em relação aos riscos maternos e fetais. Considerações Finais: A idade materna surge
como um importante determinante de desfechos adversos, reforçando a importância de intervenções de saúde
pública voltadas ao planejamento familiar, aconselhamento pré-natal intensificado e políticas de suporte à saúde
reprodutiva de adolescentes e mulheres em idade reprodutiva avançada.

Impact of rigorous muscle strength and power training on mobility among individuals with hip fractures: A randomized controlled trial
Authors: Velmurugan Varadharajan  , Pavithran Venkatesan
Published: October 2024

Patient’s mobility is not restored to pre-fracture levels until two years following a fractured hip. A persistent weakness in the muscles on the fractured leg may contribute to mobility limitations. A randomized controlled trial was conducted on individuals with hip fractures aged 60-85 to examine the effect of strength and power training twice a week on mobility. A random assignment was made between a 46-person intervention group and a 40 person control group. Over a period of twelve weeks, strength training was conducted twice per week under supervision. All measurements were conducted by a blinded measurer. We assessed mobility by timing the time it takes to climb stairs, get up from a chair, and walk. To analyze the data, we used intention-to-treat analysis. A study of efficacy was conducted for subjects who adhered to training more than 50% of the time (n = 40). 4 of the controls did not show a statistically significant improvement in mobility (p <0.001). Training had no significant effect on walking time or TUG. During the efficacy analysis, the average chair rise time for the exercise group improved by 5.4% (p < 0.005). The results of intense muscle strength and power training were observed in self-reported improvements in mobility. Participants with higher training compliance had an improved chair rise rate.

Morphology in children’s books: What’s there and what’s useful for learning?
Authors: Korochkina Maria , Rastle Kathleen
Published: October 2024

The ability to break down complex words into smaller meaningful units (e.g., unhappy = un- + happy) is a vital part of skilled reading because it allows us to rapidly access the meanings of both known and unknown printed words. In English-speaking countries, children are rarely taught explicitly how these meaningful units, known as morphemes, function, and therefore must rely primarily on their reading experience to acquire morphological knowledge. To better understand what opportunities for morpheme learning in English reading experience provides, we analysed 1,200 books popular with British children aged 7–16. We found that, although a large proportion of words in children’s books consist of several morphemes, many morphologically complex words are low in frequency and poorly distributed across the books. This scarcity suggests that it will be challenging for children to learn to recognise many complex words by sight. Our data further show that children will often be unable to draw on their experience with complex words to learn the meanings and functions of the individual morphemes. The primary cause of this is that only a few affixes are used in many distinctwords, and identifying morphemes in these words often requires sophisticated knowledge of word origins. For certain affix morphemes, this substantial learning challenge is further compounded by the fact that some words are spelled in ways that might prompt incorrect morphological parsing. Together, these factors suggest that, beyond a handful of affixes, morpheme knowledge will be difficult to acquire from print alone. We discuss the implications of these findings for theories of morpheme learning and instructional programmes in morphology.
Changes in Attitudes Toward Meat Consumption After Chatting With a Large Language Model
Authors: Karakas Neslihan , Jaeger Bastian
Published: October 2024

Researchers have started to explore the persuasive power of large language models (LLMs) and initial results suggest that LLMs are at least as persuasive as humans, even for controversial and moralized topics. Here, we tested whether a brief, open-ended conversation with ChatGPT-4o can change attitudes toward meat consumption, given that reducing meat consumption has become an important goal of many institutions due to its negative effects on the environment, health, and animal welfare. In a preregistered study, we found that participants (n = 101) reported a weaker commitment to eating meat and weaker beliefs that eating meat is necessary and natural, but not weaker beliefs that eating meat is normal or nice, after (vs. before) their conversation with ChatGPT-4o.

College science courses are increasingly transitioning from the traditional lecture format to an active learning format. Active learning have shown to improve learning outcomes and reduce failure rates. However, the interactive nature of active learning classes might lead to fear of negative evaluation among some students that prevent them from engaging in small groups, with the whole class or in conversing one-on-one with the instructor. In this paper, we report the results from two randomized controlled trials (N(study1)=903; N(study2)=817) evaluating two self-guided digital single-session interventions (SSIs) designed to bolster confidence to speak up in different contexts in an active learning class, Anx-SSI (study 1 and 2) and FNE-SSI (study 2) compared to an active control condition. In both studies, we observed that students randomized to the experimental conditions experienced an increase in confidence immediately after completing the intervention compared to the students in the control condition. Both the experimental interventions were acceptable to students. In study 1, the effects on confidence persisted at 1-week follow-up for speaking up in small groups, whole class, and total confidence as well as at 10-week follow-up for confidence in speaking up in whole class. In study 2, however, the gains in confidence did not last at 1-week or 10-week follow-up. Our studies show that brief SSIs (<30 min) can increase confidence among undergraduate students in different contexts within active learning classes. We discuss the lack of long-term effects in study 2 and potential ways to maintain immediate gains in the long-term in future studies.
Reading out bodily cues to predict interactions
Authors: Arcuri Edoardo , Ardizzi Martina , Gallese Vittorio
Published: October 2024

Successful motor coordination in social interactions requires the rapid interpretation of others’ intentions from their actions. Previous research suggests that individuals use early bodily cues, such as movement kinematics and gaze, to predict others’ behaviour. However, the motor features critical for signaling or decoding potential motor interactions remain unclear. In this study, we measured the kinematics of a basic motor act — grasping an object — executed with either individualistic (to place) or social (to pass) intentions. Subsequently, we conducted two action prediction tasks to identify bodily markers of (social) intentions. Hand positioning on the object emerged as a key kinematic indicator of the intention to interact with a partner, as shown by kinematic analyses and classification of participants’ responses. Eye-tracking analysis revealed the face as the most attended feature during action observation. Notably, these cues were more consistently attended to when observing actions from a frontal — second-person — perspective rather than a lateral — third-person — perspective. Our findings identify distinct markers of social intentions in motor acts, including goal-oriented hand-object interactions and facial signals. They also highlight the saliency of these features in decoding potential engagement in motor interactions, possibly linked to social affordance processing.
Agents can generalize to novel levels of abstraction with the help of language
Authors: Kobrock Kristina , Ohmer Xenia , Bruni Elia , Gotzner Nicole
Published: October 2024

We study abstraction in an emergent communication paradigm. In emergent communication, two artificial neural network agents develop a language while solving a communicative task. In this study, the agents play a concept-level reference game. This means that the speaker agent has to describe a concept to a listener agent, who has to pick the correct target objects that satisfy the concept. Concepts consist of multiple objects and can be either more specific, i.e. the target objects share many attributes, or more generic, i.e. the target objects share fewer attributes. We test two directions of zero-shot generalization to novel levels of abstraction: When generalizing from more generic to very specific concepts, agents utilize a compositional strategy. When generalizing from more specific to very generic concepts, agents utilize a more flexible linguistic strategy that involves reusing many messages from training. Our results provide evidence that neural network agents can learn robust concepts based on which they can generalize with the help of language. This research can help improve artificial systems and provide new hypotheses on human abstraction.

Chronic management and recurrent challenges: a case of multifocal spinal hemangiopericytoma over 7 years. Illustrative case
Authors: Moustafa Wahab , Silbermann Jörg , Badary Amr , Maksoud Salah , Khalil Al-Barbarawi Mohammad
Published: October 2024

BACKGROUND

Spinal hemangiopericytoma (sHPC) is a rare vascular tumor that presents significant challenges in diagnosis and management due to its potential for recurrence and metastasis.

OBSERVATIONS

This report documents the 7-year clinical course of a 68-year-old female diagnosed with multifocal sHPC. The patient initially presented with myelopathy due to a spinal mass, which was managed with resection, followed by several years of stability. Subsequent magnetic resonance imaging (MRI) revealed new growths, necessitating further interventions, including stereotactic radiosurgery. Despite the recurrence and progression of the disease, the strategic use of surgical and radiosurgical interventions demonstrated significant efficacy in managing tumor growth and alleviating symptoms.

LESSONS

This case emphasizes the critical importance of continual surveillance and a multidisciplinary approach in the treatment of sHPC. Continuous monitoring through regular MRI is essential for early detection of recurrences. Adaptable treatment strategies, including resection and radiosurgery, are necessary to manage the complex dynamics of tumor behavior. This report also highlights the need for patient-centered care and flexible, individualized treatment plans to ensure optimal patient outcomes in the face of recurrent and multifocal disease manifestations.

Angiographically occult spinal dural arteriovenous fistula diagnosed by exploratory surgery with intraoperative ultrasound: illustrative case
Authors: Jiang Kelly , Weber-Levine Carly , Kerensky Max J , Daniel Davidar A , Manbachi Amir , Pardo Carlos A , Gailloud Philippe , Theodore Nicholas , Jackson Christopher M , Lubelski Daniel , Sotirchos Elias S
Published: October 2024

BACKGROUND

A 78-year-old male presented with progressive myelopathic symptoms. The clinical course and imaging findings raised a high suspicion for venous hypertensive myelopathy due to a spinal dural arteriovenous fistula (SDAVF).

OBSERVATIONS

Magnetic resonance angiography and four complete spinal angiograms did not reveal the presence of an SDAVF. Despite multiple negative angiograms, intraoperative ultrasound revealed abnormal cord edema and arterialized pulsatile vessels, confirming the presence of an SDAVF. The fistula was found and cauterized, which resulted in a decrease in the caliber of the dilated veins and an observed reduction of spinal cord stiffness posttreatment. The patient exhibited gradual improvement in neurological function. Retrospective analysis of the multiple complete spinal angiograms failed to reveal an anomaly at the treated level or any other level.

LESSONS

This case underscores the diagnostic utility of intraoperative Doppler ultrasound and the importance of maintaining a high index of suspicion for SDAVF in cases with consistent clinical characteristics and a lack of alternative diagnoses, even with negative spinal angiography.

Published: October 2024

Mit wem oder was können wir solidarisch sein als Lebewesen inmitten anderer Lebewesen einer Welt, in und von der wir leben? Braucht es für ein Geo Cum noch die Festigkeit des Begriffs Solidarität, oder muss Solidarität unsolide werden? Um sich den Prozessen auflösender Stabilität anzupassen und Platz zu schaffen für eine Verantwortung, die über das Jetzt hinausreicht? In meinem zweiteiligen Beitrag gehe ich von einem von mir früher entwickelten WIHR aus: ein WIR, das das IHR immer-schon beinhaltet. Mit einem Gedicht und einer Serie von fünf Ölzeichnungen versuche ich, dieses WIHR zu einem Geo Cum hin zu öffnen und die Fragen nach einer möglichen – unsoliden – Solidarität einer mehr-als-menschlichen und zukünftigen Gemeinschaft auszuweiten.

Authors: Liang Jiale , Zhang Wenjing , Zhang Jie , He Songyue
Published: October 2024

This report aims to determine the cause of death from a forensic pathological perspective in a case of early death after heart transplantation. Using methods such as external examination, autopsy, and histopathological examination, we analyze the multiple factors leading to death in this case, particularly focusing on the heart donor aspects. Heart donors must meet strict criteria regarding structural abnormalities, age, low body weight, cold ischemia time, donor infection, and poisoning, and heart function. However, this case suggests the need for further refinement of these standards. Preoperative pathological diagnosis of the donor heart is necessary to determine any primary diseases, establish pathological diagnostic standards, evaluate heart survival indices, and ensure the quality of life for recipients, thereby avoiding deaths caused by primary diseases of the donor heart.

Authors: Li Yuanxi
Published: October 2024

Objective: To analyze the clinical diagnostic value and accuracy of microbiological testing for pulmonary aspergillosis infection.Methods: Sixty patients suspected of having pulmonary aspergillosis infection from January 2023 to June 2024 were selected. All selected patients underwent sputum culture test, galactomannan test (GM test), and 1,3-β-D-glucose (BDG) test (referred to as G test). Pathological histology examination was used as the gold standard to evaluate the diagnostic value and accuracy of sputum culture test, GM test, and G test in pulmonary aspergillosis infection. Results: In this study, histopathological examination of 60 patients showed 35 positive cases and 25 negative cases of pulmonary aspergillosis infection. The sputum culture test results showed that there were 34 positive cases, 26 negative cases, 7 false positives, and 6 false negatives of pulmonary aspergillosis infection. The GM test results showed that there were 34 positive cases, 26 negative cases, 3 false positives, and 2 false negatives of pulmonary aspergillosis infection. The G test results showed that there were 34 positive cases, 26 negative cases, 8 false positives, and 7 false negatives of pulmonary aspergillosis infection. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of the GM test were significantly higher than those of the sputum culture test and G test (P<0.05). Conclusion: The diagnostic value of the GM test in pulmonary aspergillosis infection is higher than the sputum culture test and G test, and it can be widely used.
