A clinical case of the successful use of recombinant activated VII coagulation factor in a newborn with sepsis
Authors: Trukhanova I. G. , Krugova L. V. , Kutyreva Yu. G.
Published: September 2020

Recently, in the intensive care of acquired coagulopathies in children and newborns, synthetic coagulation factors have occupied an important place, with recombinant VII activated coagulation factor (rFVIIa) being used more often. It initiates hemostasis at the site of vascular damage, forms a complex with tissue factor, and ensures maximum platelet activation. The resulting complex stimulates the transition of blood coagulation factors IX and X to the active form IXa and Xa, then factor Xa leads to increased synthesis thrombin and the formation of a stable fibrin clot. Initially, rFVIIa was developed and used to treat bleeding and surgery in patients with hereditary or acquired hemophilia and a high titer of an inhibitor to coagulation factors VIII or IX. Currently, indications for its use have expanded significantly and it is effective in intensive therapy of other acquired coagulopathy, including the occurrence of coagulopathy due to sepsis. This article presents a clinical case of the successful use of rFVIIa in a newborn with sepsis and hemocogulation disorders. The description of each case is important for the accumulation of experience and the development of further algorithms for the treatment of newborns with sepsis, accompanied by impaired hemocoagulation, since there is currently no single effective management strategy for such patients.

Authors: Donyush E. K. , Kondrashova Z. A. , Polyaev Yu. A. , Garbuzov R. V.
Published: September 2020

Vascular anomalies (VA) comprise a heterogeneous group of diseases associated with congenital angiogenesis disorder. There are no currently developed unified protocols and treatment regimens for systemic forms of VA. Numerous advantages show sirolimus, an mTOR inhibitor, as a well tolerated and effective antiproliferative and antiangiogenic therapy in patients with VA. The article presents the results of treatment of 211 patients with VA (6 patients with vascular tumors and 205 patients with vascular malformations) aged 2 months to 17 years (median – 9 years), who received sirolimus therapy for 1–86 months (median – 24 months). Sirolimus was administered at a starting dose of 0.8 mg/m2/day orally in two doses with an interval of 12 hours. The concentration of the blood preparation was maintained in the therapeutic range of 6–15 ng/ml. Since 2015, concomitant therapy with co-trimoxazole for the prevention of Pneumocystis pneumonia has been prescribed only to tracheostomy carriers. When infectious episodes occurred in patients, sirolimus therapy continued without changes in the dose of the drug and did not affect the disease, provided that the therapeutic concentration was maintained. A positive response to therapy was observed in 89.1 % of patients with VA in the form of the size of the vascular mass according to the data of visual examination and instrumental control. All patients showeda clinical response to therapy in the form of relief of painsyndrome, reduction/relief of lymphorrhea, reduction/improvement of hemostasis parameters, and an increase in functional activity and quality. For the entire observation period 2012–2020, when taking sirolimus, not a single severe adverse event occurring in post-transplant patients has been reported that would require discontinuation of the drug. The article presents two clinical cases of sirolimus use in the treatment of patients with kaposiform hemangioendothelioma and extensive venous malformation. Parents are encouraged to use the information in scientific research and publications.
Coronavirus infection COVID-19. Scientific challenges and possible ways to treat and prevent the disease
Authors: Rumyantsev A. G.
Published: September 2020

The COVID-19 pandemic has exposed pain points of decentralized healthcare systems in the global world and a failure in scientific systems analysis of old and new infections. Eighteen years ago severe acute respiratory syndrome (SARS) was underestimated and etiopathogenetic research conducted around the world was not used to develop effective treatments and prevention of the disease. Moreover, the anti-epidemic tactics in the recommendations of the World Health Organization and national health systems in the fight against the pandemic were inconsistent and relied on the historical experience of the influenza pandemic and other epidemics of respiratory infections with an emphasis on the study of the biology of the pathogen and the adaptation of society to establish biological and social balance with it.

The study of the SARS-CoV-2 virus (severe acute respiratory syndrome-related coronavirus 2) from the point of view of its origin, genome, mutated strains, damaging factors in cell culture in vitro and autopsies in experimental animals and humans in foci of infection in no way answers the question of the reasons for the various responses of the host, including asymptomatic carriage with/without the formation of an immune response; definition of syndromic complexes and their periodization; options for the uncomplicated and complicated course of the disease; outcomes, including recovery with/without the formation of specific immunity and thanatogenesis, with the search for evidence of direct or indirect involvement of SARS-CoV-2 virus in adverse outcomes.

The underestimation of the host's responses to the effects of beta-coronavirus has led to syndromic polypharmacy using more than 30 drugs with anti-inflammatory, antiviral, antibacterial, anticoagulant, immunosuppressive, and other effects, including passive immunotherapy with plasma of recovered patients or therapeutic exchange plasmapheresis. Seven months of the fight against COVID-19 led, as one would expect, to the proven effect of only tough anti-epidemic measures, personal protective measures and hygiene in the absence of effective treatment and prevention measures. In fact, an empirical selection of national and international treatment protocols with a combination of non-specific syndromic drugs is underway in the world.

The critical review discusses scientific data and hypotheses of the origin of a new coronavirus infection, human ontogenetic response to infection with SARS-CoV-2, and emerging bioinformatic concepts of the pathogenesis of the disease and approaches to pathogenetic treatment.

Authors: Kostareva I. O. , Machneva E. B. , Sidorova N. V. , Kirgizov K. I.
Published: September 2020

Veno-occlusive liver disease (VOD), now more often referred to as “sinusoidal obstruction syndrome” (SOS), is a symptom complex that develops in the early stages after hematopoietic stem cell transplantation and some chemotherapy regimens due to the toxicity of a number of drugs used and accompanied by the following symptoms: hyperbilirubinemia, fluid retention, weight gain, and painful hepatomegaly. According to various sources, the incidence of SOS/VOD in patients with oncohematological profile ranges from 3 to 15 %. At present, the standard schemes for the prevention of this condition are not fully recommended. The article presents a brief review of the literature, representing international experience in the study and treatment of SOS/VOD.

Authors: Dutra Carlos Roberto , Primo Paula Patricia , de Freitas Daniel Salvatore , Oliveira Renata Cristina , de Oliveira Ricardo Cesar Gobbi , Salvatore Freitas Karina Maria , Pinelli Valarelli Fabricio , Hermont Cançado Rodrigo
Published: September 2020

Objective:

This study aimed to compare the changes in the gummy smile in cases treated with botulinum toxin (BTX) application or orthognathic surgery.

Methods:

The retrospective sample comprised 61 subjects with gummy smile divided into 2 groups according to treatment received for gummy smile correction: 1-38 patients (6 male; 32 female), at a mean age of 28.60 years (s.d.=6.09), treated with BTX application; 2- 23 patients (7 males and 16 females) at a mean age of 29.59 years (s.d.=5.72) treated with orthognathic surgery. Patients from the BTX group refused to undergo orthognathic surgery. The measurement of the gingival exposure was performed in extraoral photographs of the posed smile, before and after treatment, and it was defined as the difference between the stomion of the upper lip and the incisal edge of the maxillary central incisor minus the height of maxillary central incisor obtained in the patient's dental casts. The data were obtained before (T1) and after treatment (T2) and change of gingival exposure with treatment (T2-T1). Intergroup comparison of gummy smile was performed with independent t-tests.

Results:

The surgical group presented significantly greater correction of the gummy smile with treatment than the BTX group.

Conclusion:

Gummy smile presented a greater improvement in patients treated with orthognathic surgery than with botulinum toxin application.
Hemicerebrum Infarction or Artifact: Effects of Out-of Center Positioning
Authors: Westerlaken Rob , van der Linden Antoine , Oosterwijk Laurien , Bok Levinus , van Pul Carola , Halbertsma Feico
Published: September 2020

Background:

CT scans are widely used for their ability to easily and rapidly obtain medical information. However, they are also vulnerable for artifacts. Fortunately, the majority is easily recognizable or is so well known that they are included in differential diagnosis on interpreting CT and rarely cause misdiagnosis or additional investigations.

Methods:

We report 2 infants with rare CT hemicerebrum density differences. They were not consistent with the clinical condition of the patients and could be classified as being artifacts after MRI proved to be normal. Retrospectively, this could have been detected on CT by examining the eyes, which also showed not otherwise explicable density differences.

Results:

These artifacts appeared to be caused by out-of center positioning, as we could demonstrate with experimental phantom scanning. We have not found any previous reports on this type of artifact.

Conclusion:

Recognition of this specific type of artifacts by observing similar density differences in the eyes does prevent unnecessary additional imaging.
Diversity of Public Health and Forensic Important Flies Using Three Measures of Hill Numbers in Iran
Authors: Keshavarzi Davoud , Rassi Yavar
Published: September 2020

Introduction:

Dipteran species (flies) are one of the most important insects within the public health and forensic fields. Previous studies have shown that flies play an important role in transmitting the diseases and also estimating the time of death, but their diversity by new methods has been less studied.

Methods:

Dipteran specimens were collected from rabbit carcasses during spring and summer 2019 and then identified. We used the three measures of Hill numbers (q=0,1,2) to compare the species diversity between the seasons. The analysis was performed with an R package (iNEXT) that provided in 2014.

Results:

During the present study, 12 dipteran species were collected on rabbit carcasses. L. cuprina and M. stabulans were recorded only from the remains of rabbits in summer. The analysis with iNEXT software showed that species richness (q = 0) in spring is lower than summer and this difference was significant. While, the value of Shannon and Simpson diversity index (q = 1, 2) in summer was lower than in spring. Shannon index value was not significantly different between the seasons, as its confidence intervals almost completely overlapped, but a significant difference in Simpson index was detected between the seasons.

Conclusion:

We conclude that Ch. albiceps, L. sericata and C.vicina are more frequent flies in the study area and dipteran species are more diverse in spring. The current study provided a database in the field of public health and forensic entomology that could be useful for estimating minimum postmortem intervals and also in vector control programs.
O trauma em "Watchmen"
Authors: Francisco André Filipe Amaral
Published: September 2020

Em 1987, Watchmen revolucionou o mundo da banda desenhada devido à complexidade dos seus super-heróis e a maneira humana como estes eram retratados. O trauma é um elemento essencial na história, uma vez que tal como afecta a população em geral, afecta também os heróis da narrativa. A série de televisão Watchmen (2019) inspira-se no ambiente e no género de herói que é retratado em 1987, tentando seguir o legado que o graphic novel deixou. Assim, esta breve reflexão foca-se na representação do trauma colectivo e individual no livro e na continuidade que lhes é dada na série de televisão, em que surgem ainda novos traumas, também eles relacionados com a narrativa inicial.
"Há algum exagero nisso"
Authors: Domingos Ana Cláudia Munari
Published: September 2020

O romance Dom Casmurro, de Machado de Assis (1899), é uma das obras mais conhecidas da literatura brasileira, uma espécie de Romeu e Julieta em vista do modo como sua fábula é reconhecida mesmo por quem não a tenha lido. Em vista disso e também pela indeterminação de suas instâncias fabulísticas, sua narrativa não é apenas adaptada para diferentes mídias como seus elementos costumam aparecer em outros diferentes textos, seja o mote do ciúme, bastante universal, sejam as características de seus personagens. Neste trabalho, mostramos como a análise intermidial da obra Capitu (Luís Fernando Carvalho, 2008), transmidiação do romance para o cinema, colabora para a compreensão daquilo que talvez não seja tão evidente na obra verbal: a visão parcial e exagerada do narrador-protagonista.   Para tanto, através das proposições de Lars Elleström (2017,no prelo), mostramos como na missérie Capitu as representações de mídias (media representation) simples, por exemplo, de mídias técnicas, e principalmente as complexas, como a do narrador romanesco e da encenação teatral, colocam em evidência essa característica do texto de Machado.

Published: September 2020

Objetivo. Caracterizar genéticamente los ovinos criollos colombianos y sus relaciones con razas de origen europeo. Materiales y métodos. 261 muestras de sangre de las siguientes poblaciones, fueron colectadas: Criollos de Lana (CL), Mora Colombiana (MC), Criollo de Pelo (CP), mestizos (Mes), Hampshire (Hamp), Corriedale (Corr), Katahdin (Kath), Pelibuey (Pel), En 40 fincas de ocho departamentos (Córdoba, Magdalena, Cesar, Atlántico, Valle del Cauca, Nariño, Boyacá y Tolima) y 30 muestras de Merino Español (ME), Merino Precoz (MP), Merinofleischschaf (MF), Segureño (Seg) y Uda (UD) de Nigeria. Un total de 15 marcadores microsatélites fueron incluidos en este estudio. Resultados. En ovinos criollos, el número promedio de alelos encontrado fue 6.20±1.48 (CL), 7.27±1.39 (CP) y 3.60±1.55 (MC); hallándose también alta diversidad genética en ellos (heterocigosidades superiores al 75%), valores negativos en el FIS revelaron alto grado de introgresión; además el FST reveló estructura genética tanto en los grupos criollos (FST=0.02**), como en los departamentos muestreados (FST=0.039**). Según la distancia genética, los ovinos criollos colombianos presentan diferencias con los ovinos foráneos. Conclusiones. Los resultados obtenidos recomiendan proteger la ovinocultura criolla puesto que se encuentra amenazada por los constantes cruzamientos con razas foráneas, lo que conllevaría a pérdida de la identidad genética y de los rasgos de adaptación propios de los animales criollos.
Dikotomi Moral dan Hukum sebagai Problem Epistemologis dalam Konstitusi Modern
Authors: Muhtamar Syafruddin , Ashri Muhammad
Published: September 2020

This article discusses dichotomy between moral and legal consideration occuring in the modern constitutions that can be traced back in the thoughts of Thomas Aquinas and Niccolo Machiavelli. The analysis focuses on the epistemological aspects of this dichotomy that are rooted for long in the moral and legal concepts in the modern constitution.Through epistemological analysis, the authors conclude that the epistemic root of the dichotomy lie in the contrasting paradigm between supernatural law and modern positivism. While modern constitutionalism constructs moral concepts that presummes Divine truth, the legal concepts oriented to rational truth. These two concepts should be intergrated without dichotomy through the dictum 'moral exaltation in the primacy of the law' so that the law will be able to answer legal issues in the society.

Philosophy, A Challenge To Post-Truth, Also in Indonesia
Authors: Magnis-Suseno Franz
Published: September 2020

This article insists that it is the task of philosophy to challenge untruth under the guise of truth. In the first part the author follows how philosophy changed from teachings of wisdom to critique of false truth claims: beginning with Eastern philosophy, with special consideration of Javanese wisdom, through Greek philosophy where philosophy comes into its own right, to M­edieval philosophy, until enlightenment clearly establishes philosophy as criticism. Hegel and Critical Philosophy are given special attention. In the second part the author stresses the importance of critical philosophy for Indonesia. He exemplifies this on three widely accepted untruths: untruth about what happened in Indonesia in 1965 and 1966, the claim that Pancasila is incompatible with liberal democracy, and the claim of religious extremism to present truth about religion. The article ends with appeal to defend our democratic freedoms without compromise.

Authors: Pratiwi Daniek Intan
Published: September 2020

This research analyses photography in the Netherlands Indies since the mid-19th century and its development until the early 20th century. The rise of photography in the Netherlands Indies as part of its modernization, is not merely the development of the arts, but photography was also used to explore the colonial territory of the colonial government. European photographers were sent to document archeological artefacts in various expeditions in several places in the archipelago.Photography also began to be commercialized. European, Chinese and even indigenous photographers arose with their photo studios. They have produced a natural and anthropological landscape of the Netherlands Indies, from Europeans and indigenous people living there. The commercialization of photography expanded with a variety of photo subjects, sold to other parts of the world in the form of albums, souvenirs or postcards. This answered the curiosity of the outside world on the Netherlands Indies as a colonial area.

Islamisasi di Kota Surakarta dan Sekitarnya Masa Orde Baru: Sebuah Tinjauan Awal
Authors: Fahrizal Adif
Published: September 2020

This article discusses the spread of Islam in the city and the neighborhood of Surakarta, Central Java during the New Order period. The spread of Islam took place through massive Islamic religious activities, such as mass prayer. In addition, the expansion of the number of mosques and mushola (Islamic praying sites) indicates a massive expansion of the influence of Islam in the region. Based on data from newspapers and interviews with relevant informants of the time, this article found out that the spread of Islam in Surakarta was a political agenda set up by the New Order government in order to counter the remnants of Communist ideology, which was withheld by sympathizers of the then Indonesian Communist Party. This article concludes that the massive spread of Islam shaped Surakarta, which had been known as the center of syncretic Javanese culture, to become religious and the government’s fear of Communism could be reduced. However, the process also made a sharp dichotomy between Islamist-based and Javanese-based identity of the city.

On other hand, the problem is the majority of students consider mathematics learning is difficult and unpleasant lesson. This research takes one of the traditional Indonesian games namely patil lele to be implicated in mathematics learning. This research used descriptive qualitative research with the aim of describing, explaining, and interpreting the implementation of traditional game patil lele as ethnomatematics qualitatively using observation, documentation, and filling questionnaires and tests. The results showed that the use of patil lele games introduce students to traditional games, foster social attitudes, collaborate with students, and help students understand the concept of distance between points. After applying traditional patil lele games, students can get to know the game. By introducing this game, students can love their own culture that is Indonesian culture with their participation in preserving traditional patil lele games. The application of traditional patil lele games can reduce the abstractness of mathematics by visualizing the material of distance between points through the game. Thus, the implementation can provide a good image of mathematics subjects students’ perspective

This research aims to describe the level of understanding the concept and critical thinking in resolving trigonometric equations using graphs. Tests and interviews were conducted to search for data and study more in the ability to understand the concepts and critical thinking skills that students have in resolving trigonometric equations using graphs. The test given to the students is a test of the explanation with the subject of his research is a class XI student. The subject selection of six students is based on the category of ability and daily replay value of the student in trigonometric materials. The six students are each – two students of high, medium and low categories. The results showed that the ability level of understanding students ' concepts in determining the set of solving trigonomic equations using graphs, gained students understanding the concept of high and moderate levels. Students with a high level of understanding are able to fulfill all indicators – an indicator of concept comprehension. Students with the level of understanding of concepts are also meeting the indicators of understanding the concept but less appropriate, which has not been able to identify the properties of a concept. Students are also less able to classify objects based on the requirements that make up the concept. The level of students ' critical thinking ability to determine the set of solving trigonomic equations using graphs obtained by the subject of students critical thinking moderate and low levels. Students with critical thinking levels are not yet able to meet interpretation indicators, i.e. students have not been able to understand and write the answer to the problem given. Students with critical thinking levels are also underprivileged to meet critical indicators of inference. Students with critical thinking levels are less able to draw conclusions, i.e. less capable of providing the right reasons for student work. Students with critical thinking levels are low, not yet capable of meeting critical thinking indicators in determining the set solving trigonometric equations using graphs. Students have not been able to meet all indicators of critical thinking ability.

This research aimed at discovering the validity and effectiveness of the interactive media of "Venn Gram" to improve the conceptual understanding of the set operations. This research was a development research (research and development). The research subjects were the students of 7th grade who consisted of nine students. The data collection techniques were in the form of a validation questionnaire and test. The subjects were in the form of pre-test and post-test questions which later the answer sheets were used as an increase of students' conceptual understanding before and after using the media. The validation questionnaire results showed that 84% of the media were very valid, 83% of the material was very valid, and 82% of the test questions were very valid. The test results found that seven students experienced an increase in the pre-test and post-test scores. Meanwhile, two other students experienced a decrease. The results of students who had increased showed that the ability of students in understanding the concept of set operations was included in the high criteria before and after using the media. The media of the Venn Gram can be used to improve the conceptual understanding of set operations.

Analysis of Mathematic Representation Ability of Informatics Engineering Students in Assignment Problems
Authors: Shofia Niska , Rochana Siti , Widodo Suryo
Published: September 2020

Mathematics is a field of science that can improve a person's ability to think logically, critically, rationalistically, effectively, carefully and efficiently. To find out a person's ability to think logically, critically, rationalistically, effectively, carefully and efficiently in solving mathematical problems, an analysis of mathematical representations is needed. Mathematical representation is needed in solving Operations Research problems, because operations research uses a mathematical model as a problem-solving approach. This research discusses the mathematical representation ability of informatics engineering students at Nusantara University PGRI Kediri in solving assignment problems in Operations Research courses. The research method used includes descriptive research with a qualitative research approach. Data were taken directly from the research location using interviews and tests on 3 research subjects, namely students with high, medium and low abilities. The subject selection is based on the results of the dialogue between the researcher and the student's mathematics subject lecturer. Based on the results of research, high-ability students can complete multiple representations both visually, symbolically and verbally. Likewise for the mathematical representation of moderate-capable students is having multiple representations, but there are steps in solving that are missed in verbal representations. Low-ability students only provide visual and verbal representations, while symbolic representations still have errors. However, all three are still lacking in terms of the implementation of the final results

Uma garota propaganda para o império: o caso de Rosinha na Exposição do Porto de 1934
Authors: Silva Franco Santos Alves da
Published: September 2020

Durante a 1ª Exposição Colonial Portuguesa em 1934, na cidade do Porto entre junho e setembro de 1934, havia uma negra chamada Rosinha, proveniente da Guiné do grupo étnico Balanta que se tornou atração no pavilhão daquela colônia. Registrada, em pose erotizada, pelas lentes de Domingos Alvão, Rosinha inspirou esculturas, estampas, cartões-postais, propagandas, capas de revistas e charges que viam nela uma musa - uma “portuguesa” – que personificava o projeto integrador.
Imagens e Palavras na escritura da Narrativa Etnofotográfica: Notações Metodológicas
Authors: Fernandes Daniel dos Santos , Fernandes José Guilherme dos Santos
Published: September 2020

O uso de imagens tem crescido significativamente na pesquisa acadêmica a partir do último quartel do século XX, apesar deste uso não ser uma novidade, já que antropólogos como Malinowski (Argonauts of the Western Pacific. An Account of Native Enterprise and Adventure in the Archipelagoes of Melanesian New Guinea, 1922), Margareth Mead e Gregory Bateson (Balinese Character, 1942), Lévi-Strauss (La Vie familiale et sociale des Indiens Nambikwara, 1948), entre outros, durante suas pesquisas de campo, fizeram uso de  imagens, sejam fotografias ou vídeos . Este caminhar do uso da fotografia se faz até hoje a partir da tensão causada pela possibilidade desta integrar a escritura acadêmica, não mais como mero instrumento ou ilustração, mas como outra escritura, não excludente, mas em diálogo com a escrita, e que consiga visibilizar de que forma as subjetividades são objetivadas.  Daí entender-se a produção final do etnógrafo não mais como uma escrita, mas uma escritura, compreendendo-se esta como estratégia de produção de sentido em determinado texto, não somente uma técnica de inscrição textual ou um suporte material da linguagem verbal e não verbal, isto é, o texto como imagens, palavras, sons. Razão pela qual que nossa consideração pelo conceito de etnofotografia seja em razão do acento na perspectiva antropológica do uso da fotografia (o ensaio fotográfico como sequência narrativa), para além de uma finalidade artística, pautada no registro cênico de aspectos de uma cultura, preocupada com experimentalismos imagéticos e na desorganização e aleatoriedade da imagem. E é do uso sistemático da fotografia na pesquisa etnográfica que iremos analisar e propor um caminho metodológico.
