MORPHOLOGICAL AND FUNCTIONAL CHANGES OF INTESTINAL MUCOSA AT ACUTE NECROTIZING PANCREATITIS
Authors: O V. Rotar
Published: November 2021

The purpose - to investigate the morphological and functional changes of the intestinal mucosa during acute necrotic pancreatitis and their effect on the translocation of bacteria and endotoxin. Material and methods. The conditions of the intestinal barrier were studied at 74 patients in clinics and 60 white rats in experiment during acute necrotic pancreatitis. The morphological and histological changes of the mucosal layer of the intestine, its enzyme activity, the microflora and its permeability for the endotoxin were studied. Results and discussion. During the early phase of acute necrotic pancreatitis barrier function of the intestine has been disturbed by increasing the activity of lysosomal enzymes (β-galactosidase double and N-acetyl-β-glucosaminidase triple, p <0.05), which caused the qualitative and quantitative changes of composition of glycoproteins in the epithelial layer of the mucosa shells. Disorders of the intestinal barrier were accompanied by bacterial translocation to the internal organs in 57.4% of patients who were operated early (up to 4 weeks) of the disease and in 90% of the animals after 72 hours of the experiment. High concentrations of endotoxin (over than 0.30EO/ml) delivered from the intestine have activated a specific proinflammatory cascade through the membrane receptor of monocytes/macrophages CD14, which was accompanied by the development of a systemic inflammatory response syndrome and multiple organ failure. Conclusions. During acute necrotizing pancreatitis the structure and protective function of the pre-epithelial mucosal layer are disordered, colonization of intestine by pathogenic and conditionally pathogenic gram-negative microflora is occurred which promoted migration of bacteria and transport of endotoxin into systemic blood circulation.

Philosophical issues of artificial intelligence and “smart” algorithms’ trust in medicine
Authors: Georgiou TS
Published: November 2021

In this article, the author examines the philosophical issues associated with the introduction of artificial intelligence (AI) systems in medicine. Currently, the use of AI technologies in the field of medical sciences is one of the most important trends in the world of health. ‘Smart’ AI systems are able to learn from their own experience, adapt in the environment and, according to the parameters of the assigned tasks, can make decisions that in the past belonged only to humans. These AI technologies provide an opportunity to take diagnostics, treatment and disease prevention to a higher level. Particular attention is paid to the ethics and moral obligations of AI developers and healthcare professionals in the transition to such digital medicine.
Who is the Diaspora? The Negotiation of Diasporic Identities in the Romanian Online Political Discourse
Authors:   National University of Political Studies and Public Administration, Bucharest, Romania, TOADER Florența
Published: November 2021

Drawing on an interdisciplinary framework based on critical and pragmatic discourse analysis, this study investigates the way Romanian politicians negotiate the identity of the Romanian diaspora on their Facebook pages. It also points out to the way discourse is used to introduce and (de)legitimize political decisions and actions. The topic is analyzed in different political and social contexts: the presidential elections in 2014 and 2019, the Euro-parliamentary elections in 2019, and the crisis generated by the comeback of the Romanians abroad as a result of the corona-virus pandemics in 2020. The results of the study show that the diaspora is part of the political discourse as a topic mainly during electoral periods, which are more heavily stake driven. The subject of the diaspora was approached by political actors in a strategic manner, starting from their communication project and the political outcome they were aiming for. The paper contributes to the growing body of knowledge on strategies of constructing diasporic identities in the political discourse. The paper also illustrates spe-cific and emergent strategies of diasporic identity construction in different political and social contexts in a social media environment.
Headlines against Democracy: Operational Code Analysis of the Serbian Daily Informer’s Headlines in Relation to the Anti-Government Protests’ First Phase (2018–2019)
Authors:   Faculty of History, Nankai University, Tianjin, China, JOVANOVIĆ Srđan Mladenov
Published: November 2021

Since late 2019, Serbia has been gripped in a wave of protests against, as scholarly research has dubbed it, the semi-authoritarian regime of President Aleksandar Vučić. Having in mind that the President’s regime has by known been uncovered to rule by direct and indirect control of the media, the arguably main government-supporting daily newspaper, the Informer, has been covering the protests avidly, and with significant vitriol. With the understanding a headline is seen by the reader more commonly than the whole body of the article and having in mind the Informer’s pro-clivity towards exaggeration and hyperbole, we have analyzed all of the daily’s headlines that refer to the protests, protesters, or protest/opposition leaders during the so-called ‘First phase of the protests’ via the methodo-logical position of Operational Code Analysis. The paper shows a fairly extreme OPCODE for the Informer.
Is “Letting the Truth Get in the Way of a Good Story” Enough? Journalists’ Perception on Fake News
Authors:   National University of Political Studies and Public Administration, Bucharest, Romania, DUMITRU Elena-Alexandra
Published: November 2021

While numerous scholars have studied the role media has in the fake news phenomenon, journalists’ perception on disinformation has been insufficiently approached, and only from a US and West-European point of view. Based on interviews with eight traditional media and new media professionals, this study seeks to add to the understanding of the way journalists from an East-European country see fake news in an environment influenced by time pressure and external immixture in the media. The findings show that even though all interviewed journalists place great value on fact-checking, they happened to publish information that later was demonstrated to not be trustworthy. While journalists perceive disinformation in a deeply negative manner, many of the things that add to the spread of fake news cannot be controlled by journalists as a part.
How the COVID-19 Pandemic Has Influenced Central Bank Communication on Social Media. An Analysis of Two Major Central Banks from the Anglo-Saxon economies
Authors:   National University of Political Studies and Public Administration, Bucharest, Romania, VOLOC Ana-Maria 
Published: November 2021

This study examines how central banks communicate on social media during the COVID-19 pandemic, and whether they are using these technologies to create a bidirectional communication or to increase their transparency by reaching a wider audience. The research method used for this purpose is content analysis, by investigating the information provided on the Twitter pages of two major central banks from the Anglo-Saxon economies: the Federal Reserve and the Bank of England. To be more specific, the current study is focused on the impact of the COVID-19 pandemic on the relationship between central banks and the public (if they interact with their audience by responding to comments or creating debate topics that engage the public or they just offer information about their decisions or measures to mitigate the negative effects of the pandemic on the economy), and the type of content central banks prefer (articles, online events, pictures or videos). The results show that central banks use social media and other forms of communication for the primary purpose of giving information about their efforts to ensure macroeconomic and financial stability, rather than for creating an open dialogue with the public.

Published: November 2021

Objective: To detect the expression and distribution of I-FABP in intestinal tissue and the changes of serum concentrations at different time of acute intestinal ischemia, and explore the significance and mechanism of I-FABP in early diagnosis of acute ischemic bowel disease. Methods: The selected 96 healthy adult SD rats were randomly divided into the experimental group and control group; 48 in each group. Each group was randomly subdivided into 6 groups with 8 rats in each group. The superior mesenteric artery was ligated in the experimental group and the peritoneal switch operation was performed in the control group. The venous blood samples were extracted from each group rats’ right ventricle at 0.5 h, 1 h, 2 h, 4 h, 8 h, 12 h after the operation and the concentration of I-FABP was tested respectively. Then the rats were killed, and the diseased intestinal tubes were cut out for paraffin sections. The I-FABP in intestinal tissue was stained by routine HE staining and direct immunofluorescence staining. Results: The I-FABP was mainly expressed in the epithelial villi of intestinal mucosa, and there was a small amount of expression in the intestinal submucosa and even the muscularis. Within 1 hour of intestinal ischemia, the number of I-FABP positive granules in the intestine and intestinal cavity increased gradually, and then gradually decreased after 1 hour. The difference has statistically significant between the experimental group and the control group (P < 0.05). The serum I-FABP: In the experimental group, the serum I-FABP concentration began to increase at 0.5 h, and reached a peak at 1 h (290. 24 ± 156.69) μg·L–1, then gradually decreased. Compared with the control group, the difference was statistically significant (P < 0.05). Conclusion: I-FABP usually mainly exists in the epithelial cells of intestinal mucosa. When acute intestinal ischemia occurs, the epithelial cells of intestinal mucosa permeability changes; I-FABP expression rapidly releases to intestinal tissue and intestinal cavity, and is absorbed into the blood. Therefore, I-FABP has certain clinical significance in early diagnosis and treatment of acute intestinal ischemia.
The Role of Family Firms Heterogeneity on the Internationalisation and Performance Relationship
Authors: Rienda Laura , Andreu Rosario
Published: November 2021

Many papers have addressed the influence of different characteristics of family businesses on strategic decisions, including those of internationalisation. However, little is known about the relationship between the internationalization of family firms and firm profitability. For this reason, from the socioemotional wealth perspective, in this paper, we focus on the moderating role of some heterogeneous characteristics of family firms on the relationship between internationalisation and business performance. Specifically, we analyse a sample of 76 companies belonging to the Spanish hotel industry, one of the most internationalised sectors and with a large presence of family businesses. The results show that family involvement in ownership and management, as well as generation, moderates the relationship between internationalisation and profitability in the Spanish hotel industry.
Teleonomía y función biológica. Una investigación sobre las raíces y las virtualidades de la teleonomía según Konrad Lorenz
Authors: Durieux Montoya Laura
Published: November 2021

Esta investigación trata de la cosmovisión reflexiva y crítica sobre el papel de la finalidad en la biología elaboradas por Konrad Lorenz. Se trata de una investigación en filosofía y no en biología, por lo que las principales aportaciones de Lorenz a la Etología se insertan en el marco teórico definido por los conceptos de (i.) organismo en Kant, (ii.) evolución adaptativa en Darwin y (iii.)  recuperación de la finalidad como teleonomía. Lorenz rechaza la teleología de raigambre aristotélica, y propone un modelo teórico en biología de raíces kantianas y hartmantianas. Se trata de un modelo explicativo en biología. Mi intención en esta investigación radica en explorar las raíces y las virtualidades del modelo explicativo de la finalidad en biología propuesto por el etólogo austriaco.
About uniformly Lindelöf spaces
Authors: Kanetov Bekbolot E. , Saktanov Ulukbek A. , Zhanakunova Meerim O.
Published: November 2021

The idea of Lindelöfness is one of the most important in General Topology. There have been some variants in defining uniformly Lindelöfness of uniform spaces. For example, uniform A-Lindelöfness in the sense of L.V. Aparina [1], uniform B-Lindelöfness in the sense of A.A. Borubaev [2], uniform I-Lindelöfness in the sense of D.R. Isbell [5].

In this paper we propose a new approach to the definition of a uniform analogue of Lindelöfness. We introduce and study uniformly Lindelöf spaces.
Optimization of the loading pattern of the PWR core using genetic algorithms and multi-purpose fitness function
Authors: Kubiński Wojciech , Darnowski Piotr , Chęć Kamil
Published: November 2021

The study demonstrates an application of genetic algorithms (GAs) in the optimization of the first core loading pattern. The Massachusetts Institute of Technology (MIT) BEAVRS pressurized water reactor (PWR) model was applied with PARCS nodal-diffusion core simulator coupled with GA numerical tool to perform pattern selection. In principle, GAs have been successfully used in many nuclear engineering problems such as core geometry optimization and fuel configuration. In many cases, however, these analyses focused on optimizing only a single parameter, such as the effective neutron multiplication factor (k
eff), and often limited to the simplified core model. On the contrary, the GAs developed in this work are equipped with multiple-purpose fitness function (FF) and allow the optimization of more than one parameter at the same time, and these were applied to a realistic full-core problem. The main parameters of interest in this study were the total power peaking factor (PPF) and the length of the fuel cycle. The basic purpose of this study was to improve the economics by finding longer fuel cycle with more uniform power/flux distribution. Proper FFs were developed, tested, and implemented and their results were compared with the reference BEAVRS first fuel cycle. In the two analysed test scenarios, it was possible to extend the first fuel cycle while maintaining lower or similar PPF, in comparison with the BEAVRS core, but for the price of increased initial reactivity.

Published: November 2021

Operation of marine diesel engines causes significant emission of sulphur and nitrogen oxides. It was noticed worldwide and the regulations concerning harmful emissions were introduced. There were several solutions elaborated; however, emission control for both SOx and NOx requires two distinctive processes realized in separated devices, which is problematic due to limited space on ship board and high overall costs. Therefore, the electron beam flue gas treatment (EBFGT) process was adopted to ensure the abatement of the problem of marine diesel off-gases. This novel solution combines two main processes: first the flue gas is irradiated with electron beam where NO and SO2 are oxidized; the second stage is wet scrubbing to remove both pollutants with high efficiency. Laboratory tests showed that this process could be effectively applied to remove SO2 and NOx from diesel engine off-gases. Different compositions of absorbing solution with three different oxidants (NaClO, NaClO2 and NaClO3) were tested. The highest NOx removal efficiency (>96%) was obtained when seawater-NaClO2-NaOH was used as scrubber solution at 10.9 kGy dose. The process was further tested in real maritime conditions at Riga shipyard, Latvia. More than 45% NOx was removed at a 5.5 kGy dose, corresponding to 4800 Nm3/h off-gases arising from ship emission. The operation of the plant was the first case of examination of the hybrid electron beam technology in real conditions. Taking into account the experiment conditions, good agreement was obtained with laboratory tests. The results obtained in Riga shipyard provided valuable information for the application of this technology for control of large cargo ship emission.

PyTorch Operations Based Approach for Computing Local Binary Patterns
Authors: Akgun Devrim
Published: November 2021

Advances in machine learning frameworks like PyTorch provides users with various machine learning algorithms together with general purpose operations. PyTorch framework provides Numpy like functions and makes it practical to use computational resources for accelerating computations. Also users may define their custom layers or operations for feature extraction algorithms based on the tensor operations. In this paper, Local Binary Patterns (LBP) which is one of the important feature extraction approaches in computer vision were realized using tensor operations of PyTorch framework. The algorithm was written both using Python code with standard libraries and tensor operations of PyTorch in Python. According to experimental measurements which were realized for various batches of images, the algorithm based on tensor operations considerably reduced the computation time and provides significant accelerations over Python implementation with standard libraries.

Authors: B. S. Premananda , T. N. Dhanush , Parashar Vaishnavi S. , Bharadwaj D. Aneesh
Published: November 2021

Phase-locked loop (PLL) operates at a high frequency and due to the increased switching rate of the circuits, the power consumption is high. Designing a PLL which consumes less power without compromising the frequency of operation is essential. The sub-components of PLL such as the phase frequency detector, charge pump, loop filter, voltage-controlled oscillator, and the frequency divider have to be designed for reduced power consumption. The proposed PLL along with its sub-components have been designed using the CMOS 180nm technology library in the Cadence Virtuoso and simulated using Cadence Spectre with a supply voltage of 1.8V resulting in a 20% reduction in power with a higher frequency of operation compared to the reference PLL architecture. The capture range and lock range of the proposed PLL are 2.09 to 2.14 GHz and 1 to 3.5GHz, respectively. The designed PLL consumes less power and operates at a higher frequency.
Oxygen Sensors for Industrial Application
Authors: Nhanga José
Published: November 2021

The present work aimed to study a family of solid ceramic electrolytes based on magnesium oxide doped zirconium oxide, usually identified as Mg-PSZ (zirconia partially stabilized with magnesia), used in the manufacture of oxygen sensors for molten metals. A set of electrolytes was prepared by mechanical (milling) and thermal (sintering) processing, varying the composition in magnesia and the cooling rate from the sintering temperature. These two parameters are essential in terms of phase composition and microstructure of Mg-PSZ, determining the behavior of these materials. The structural and microstructural characterization was done by means of X-ray diffraction (XRD). The electrical properties were analyzed by impedance spectroscopy in air. In general, the results obtained from various concentrations of dopant, different cooling rates and the same sintering step condition showed an increased conductivity for samples with predominance of high temperature stable phases (tetragonal and cubic).
Brief Review on Electrocardiogram Analysis and Classification Techniques with Machine Learning Approaches
Authors: Borghi de Melo Pedro Henrique
Published: November 2021

Electrocardiogram captures the electrical activity of the heart. The signal obtained can be used for various purposes such as emotion recognition, heart rate measuring and the main one, cardiac disease diagnosis. But ECG analysis and classification require experienced specialists once it presents high variability and suffers interferences from noises and artefacts. With the increase of data amount on long term records, it might lead to long term dependencies and the process become exhaustive and error prone. Automated systems associated with signal processing techniques aim to help on these tasks by improving the quality of data, extracting meaningful features, selecting the most suitable and training machine learning models to capture and generalize its behaviour.
This review brings a brief stage sense of how data flows into these approaches and somewhat techniques are most used. It ends by presenting some of the countless applications that can be found in the research community.
Musik und Kirche unter dem Einfluss der nationalsozialistischen Diktatur in Südtirol
Authors: Pinggera Mario
Published: November 2021

Wer sich mit dem Nationalsozialismus beschäftigt, setzt sich immer auch mit einem Tiefpunkt der Menschheitsgeschichte auseinander. Auch die Musik blieb vom harschen Zugriff durch die Nationalsozialisten nicht verschont. Im Gegenteil: Die Nationalsozialisten machten sich gerade die Musik und damit die Musizierenden voll und ganz zu Nutze. Diese Arbeit will nicht nach Schuldigen suchen oder gar ein Urteil fällen. Vielmehr geht der Autor der Frage nach, wie es in einem fast schon archaisch katholischen Land wie Südtirol möglich war, dass die nationalsozialistische Ideologie einen so grossen Anklang fand – denn die katholische Lehre und das menschenverachtende System des Nationalsozialismus sind per definitionem unvereinbar. Dasselbe gilt für kirchliche und kirchennahe Musik: Auch sie gehen mit einer Diktatur grundsätzlich nicht zusammen.
Does the Inclusion of Second Generation Genetically Modified Plants in Feeds have any effect on Animal Performance?
Authors: Matovu Jacob
Published: November 2021

The need for studies on the nutritional value of plants depends on their composition. The first generation genetically modified Plants (GMPs) have the same composition as their near-isogenic lines. Therefore, they have the same nutritional value, and most of the animal feeding studies have found no significant differences in the production and health parameters of animals that consumed first-generation GMPs in comparison to non-GMPs. Due to the recent production of transgenic plants with specific nutritional properties (second generation GMPs), their use as feed for animals is viewed with skepticism in very many countries. In this critical review, it is concluded that most of these nutritionally improved plants have not shown adverse effects on the performance of various animals compared to their near-isogenic lines and can therefore be considered in the animal feed industry. However, most of the experiments were conducted on laboratory animals. There is a need to conduct them with animals that are mainly consumed by humans, such as ruminants. There is also a need to feed the whole plant to these animals and not just certain parts of the plant to get a clear picture of its overall safety. In addition, there is a need to determine a suitable long-term nutritional and toxicological approach assessment.

Published: November 2021

Nano-refrigerant is announced to become an excellent refrigerant, which often improves heat transfer efficiency in the cooling systems. Different materials can be applied to be suspended in traditional coolants in the same way as nanoparticles. In this comprehensive research, mathematical modeling was used to investigate the effect of suspended nanoparticles (Al2O3, CuO, SiO2 and ZnO) on 1,1,1,2-Tetrafluoroethane, R-134a. The thermal conductivity, dynamic viscosity, density and specific heat capacity of the nano-refrigerant in an evaporator pipe were investigated. Compared to conventional refrigerants, the maximum increase in thermal conductivity was achieved by Al2O3/R-134a (96.23%) at a volume concentration of 0.04. At the same time, all nano-refrigerant types presented the same viscosity enhancement of(45.89%) at the same conditions. These types of complex thermophysical properties have enhanced the heat transfer tendencies in the pipe. Finally, the nano-refrigerant could be a likely working fluid generally used in the cooling unit to improve high-temperature transfer characteristics and save energy use.
“Bread for the People and National Security”: Soviet commercial diplomacy during the period of détente
Authors: Yakupova Dar'ya Viktorovna , Yakupov Roman Aleksandrovich
Published: November 2021

The relevance of this research is defined by the need for analyzing the historical experience of adaptation of foreign economic activity of the Soviet State to the challenges of Western policy deterrence, the imperatives of which are being applied to Russia in the current context. The subject of this research is the Soviet grain procurement crisis and foreign policy ways for its overcoming. The object of this research is trade and diplomatic relations between the Soviet Union and the United States. The scientific novelty lies in elaboration of the concept of “commercial diplomacy” – the foreign economic activity of the USSR government aimed at solution of the domestic problems and tasks of modernization. Leaning on the newly introduced sources, the conclusion is made that the policy of commercial diplomacy implemented by the Soviet Union suggested the use of international dialogue within the framework of cooperation between the governments and public-private business circles on achieving the economic goals associated with the national interests of the Soviet Union. The critical need for grain procurement, discovery of the oil resources potential, and détente in the international relations between the two superpowers led to a new round in the Soviet Union – United States relations. It is underlined that grain and oil manifested as the factor of maintaining domestic political stability and the object of foreign policy exchange. The article answers the question: how the grain procurement problem has transformed from the economic into social issue, and the grain import has become the vulnerable spot of the Soviet Union in the ideological confrontation with the United States, and the object of international relations.

The subject of this research is museum sources on the religion of Bashkir people. The goal lies in examination of the items of Islam and pre-Islamic beliefs from the ethnographic collections of the Museum of Archeology and Ethnography of R. G. Kuzeev Institute of Ethnological Research of the Ufa Federal Research Center of the Russian Academy of Sciences. It is determined that the Museum stores over 50 items related to religion that were collected in the late XX century in the Republic of Bashkortostan, Kurgan Oblast, and Orenburg Oblast. These Islamic (Sunni Muslims) items are rather associated with the traditions and lifestyle of the Bashkir people: prayer rugs – namazlik, Quran, tasbih, tagiyah, ablution items – kumgan, dress of the Mullah. Prayer rugs are decorated with floral embroidery, with images of mosque, kumgan, crescent moon, and Arabic inscription. The collections also feature the items related to Shia Muslims – a stone used in prayer. Islam first infiltrated Bashkir culture in the X – XI centuries; by the XIII – XIV century it spread significantly; strengthening its positions with each century, it has fully integrated into life of Bashkir population by the end of the XIX century. Despite this fact, certain items pre-Islamic beliefs have retained in everyday life of the Bashkir people: amulets (amulet stones, juniper, feathers of wood grouse, goose down, etc.). Bashkirs were able to synthesize the pre-Islamic and Islamic tradition, which remain existing harmoniously in the territory of the Republic of Bashkortostan.

O objetivo deste artigo é apresentar uma revisão de escopo sobre as características prosódicas associadas aos sinais de pontuação. Foi realizado um levantamento bibliográfico a partir da pesquisa de descritores em inglês e português, organizados de acordo com a seguinte sintaxe: prosódia AND acústica AND discurso AND estrutura AND ("sinais de pontuação" OR "pontuação gráfica" OR "sinal de pontuação"), sem incluir citações e patentes nas bases de dados: OvidMedlin, Public Medicine Library (PubMed), Scopus (Elsevier), Ebscohost (Academic Search Premier), Gale Academic Online e Google Scholar. Observamos que existe uma diversidade de métodos empregados para analisar a correlação entre os sinais de pontuação e as características prosódicas. Os estudos desta revisão confirmaram nossa pergunta de pesquisa, evidenciando a relação entre os sinais de pontuação e os aspectos prosódicos. A maioria dos trabalhos relacionados à tecnologia desenvolveu diferentes redes neurais para transformar texto em fala e/ou para converter fala em texto e mostrou que as pausas são apontadas como indicadores mais fortes dos sinais de pontuação.

O objetivo desta pesquisa é buscar compreender os processos de aquisição/aprendizagem de uma criança que desde 1 ano e 3 meses de idade faz aulas particulares de inglês em uma escola de idiomas. O caso estudado se distingue dos contextos das escolas bilíngues e das escolas de idiomas, entre outros fatores, pelo fato de a interação entre criança-professora ocorrer sempre em inglês, de ser apenas uma criança na sala de aula e de haver uma proposta de interação mais próxima da criança, com atividades lúdicas etc. A partir da perspectiva dialógico-discursiva (BAKHTIN/VOLOSHINOV, 1995; DEL RÉ, DE PAULA, MENDONÇA, 2014) e, ainda, considerando os gêneros do discurso em diálogo com a noção de formatos (BRUNER, 1975, entre outros) e a multimodalidade (CAVALCANTE, 2015, 2019), observamos os elementos presentes na interação e na constituição desse sujeito entrando na segunda língua. A transcrição dos dados foi feita a partir das normas CHAT/CLAN, fornecido gratuitamente pela base de dados CHILDES (MACWINNEY, 2000), e foram analisados dados entre 2;10 e 3;7 anos. Os resultados mostram elementos presentes nessa interação que servem de apoio para que o processo de aquisição/aprendizagem da segunda língua aconteça. Os gêneros e os formatos alicerçam a entrada na L2, assim como a afetividade, proximidade entre a criança e a professora, a liberdade de escolha, entre outros, promovendo uma interação muito próxima daquela da esfera familiar. Além disso, os elementos multimodais ancoram essa interação, possibilitando que G. tenha uma atitude responsiva desde o início das interações nesse ambiente escolar.

Authors: Salazar Trujillo M. A.
Published: November 2021

Objective. To evaluate the efficacy of the use of a last generation hydrofiber dressing with silver, for the treatment of complex wounds that are difficult to heal.

Materials and research methods. A prospective observational case-follow-up study was carried out, which included patients with acute or chronic wounds that were difficult to heal, treated in the plastic surgery service of a public hospital in Bogota-Colombia, who underwent healing with hydrofiber dressings reinforced, with silver ions, benzethonium chloride and EDTA (Aquacel Agplus®, ConvaTec). The wound was monitored, evaluating infection control, exudate and biofilm, as well as the number of required dressings and the time required for the complete closure of the wound.

Research results. A total of 55 patients were included, with a median age of 44 years. In all cases, a follow-up was carried out until the definitive closure of the wound. At the end of the study, it was observed that, in 35 (63.6 %) patients, the wounds evolved to complete closure by second intention in an average of 59.3 days, requiring 12.5 dressings. 20 (36.4 %) patients had adequate wound bed preparation for definitive surgical coverage with grafts, flaps or dermal substitutes, in an average of 31.4 days, requiring 6.5 dressings on average.

33 (60.0 %) wounds were infected and adequate infection control was achieved on average with 5 dressings. A decrease in the direct and indirect signs of biofilm was achieved after 6 dressings.

Conclusion. The results show that the dressing studied is effective to control exudate, infection and biofilm, as well as to prepare the bed for a definitive surgical coverage.

Coronavirus disease 2019 (COVID-19) originated in China in early March 2019. Saudi Food and Drug Authority approved the registration of the Pfizer-BioNTech COVID-19 vaccine in Saudi Arabia on December 10, 2020, and on May 10, 2021, Pfizer-BioNTech was given an authorized emergency use in 12–15-years-old children. Saudi Arabia’s Ministry of Health started Pfizer-BioNTech COVID-19 vaccination for 12–18-years-old on June 27, 2021. Here, we have a case of a 16-year-old female admitted to the medical ward diagnosed with acute inflammatory transverse myelitis after 2 weeks from second dose of the Pfizer-BioNTech COVID-19 vaccine. The diagnosis was based on normal laboratory workup but significant radiological findings. She was discharged after a full recovery. There are multiple cases of post-vaccine acute inflammatory transverse myelitis shared by medical journals, but due to lack of literature review for the teenager population, we think our case may be the first case of acute inflammatory transverse myelitis following second dose of Pfizer-BioNTech COVID-19 vaccine in this population.

L’analyse floristique de 22 relevés réalisés dans la cédraie du massif forestier d’Ait Ouabane a révélé l’existence de 135 taxons, appartenant à 115 genres et 42 familles, essentiellement les Asteraceae et les Rosaceae, et à plusieurs types chorologiques. Les hémicryptophytes dominent dans le spectre biologique. L’analyse des types chorologiques montre la prédominance de l’élément méditerranéen, avec un faible pourcentage d’endémisme. Les résultats montrent une diversité importante de la flore, qui se présente globalement comme une flore méditerranéenne typique, et caractérisant des habitats à grande valeur patrimoniale.
