Assessing Clinical Feasibility and Safety of Percutaneous Dilatational Tracheostomy During Extracorporeal Membrane Oxygenation Support in the Intensive Care Unit
Authors: Hong Tae Hwa , Kim Hyung Won , Kim Hyoung Soo , Park Sunghoon
Published: March 2022

Purpose: A tracheostomy is often used to wean patients off the ventilator, as it helps maintain extracorporeal membrane oxygenation (ECMO) without sedation. A percutaneous dilatational tracheostomy (PDT) performed in critically ill patients is widely accepted, however, its feasibility and safety in ECMO is unclear.Methods: This retrospective observational study included 78 patients who underwent a PDT and ECMO at the surgical intensive care unit (SICU) in a tertiary hospital between January 1, 2016 and December 31, 2019. We analyzed their medical records, including PDT-related complications and clinical variables.Results: The median values of hemoglobin, platelet count, international normalized ratio, partial thromboplastin time, and activated partial thromboplastin time before the tracheostomy were 9.2 (8.5-10.2) g/dL, 81 (56-103) × 103/dL, 1.22 (1.13-1.30), 15.2 (14.3-16.1) seconds, and 55.1 (47.4-61.1) seconds, respectively. No clotting was observed within the extracorporeal circuit, however, minimal bleeding was observed at the tracheostomy site in 10 (12.8%) patients. Of 4 patients with major bleeding, local hemorrhage was controlled in 3 patients, and intratracheal bleeding continued in 1 patient. The mortality rate was 60.9% and 57.1% in the complication and no-complication group, respectively. The durations of SICU stay, hospital stay, and mechanical ventilation were not statistically different between the groups.Conclusion: A PDT performed in critically ill patients was associated with a low rate of bleeding. Complications did not appear to significantly affect the patient outcome. PDT can be performed in patients who usually require a tracheostomy to maintain ECMO.

Authors: Kang Seok Min , Kim Im-kyung , Lee Jae Gil
Published: March 2022

Purpose: Traumatic duodenal injury is uncommon and due to its difficult diagnosis and accessibility there is an increased risk of mortality and morbidity.Methods: Electronic medical records of a single center were reviewed retrospectively from March 2008 to December 2020 and a total of 7 cases of traumatic duodenal injury were managed by surgical exploration. The site of duodenal perforation, injury mechanisms, operation method, and postoperative outcomes were assessed.Results: The mean age was 55.72 years (range, 34-78), and there were 5 men in the study. The most common mechanism was in-car traffic accident (4 cases), and 1 case each of pedestrian accident, accident during work, and self-injured stab wound. The most common site of injury was between the 3rd and 4th portion (3 cases), followed by the bulb and 1st portion (2 cases), and 2nd portion (2 cases). Segmental resection of the duodenum and primary anastomosis was performed in the 3rd and 4th portion perforation. In cases of 1st and 2nd portion, injury was managed by primary repair or pylorus preserving pancreaticoduodenectomy. Complications developed in 4 patients, and the most common complication was a problem with the wound; wound seromas developed in 4 cases, entero-cutaneous fistula in 1, and biliary complications in 2 cases. Two patients suffered from intraperitoneal abscess or fluid collection managed by percutaneous drainage. The mean duration of hospital stay was 34 days, and postoperative mortality did not develop.Conclusion: Favorable clinical outcomes were observed in patients with traumatic duodenal injury managed by various surgical approaches.

Authors: Kim Hyung Won , Park Bo Ram , Hong Tae Hwa
Published: March 2022

Purpose: Despite advances in diagnostic and imaging technologies, the diagnosis of traumatic hollow viscus injury (HVI) remains a great challenge in clinical practice. This study aimed to determine the accuracy of computed tomography (CT) in the diagnosis of HVI in emergent blunt trauma patients.Methods: The study was conducted on patients with abdominal trauma who were admitted to our center, regional emergency center, Kyung Hee University Medical Center, between January 2008 and December 2018. The clinical data of patients with abdominal trauma who underwent CT and abdominal surgery within 24 hours of hospitalization were analyzed to determine the diagnostic capacity of CT.Results: In total, 156 patients were included in the study. There were 88 cases of blunt trauma. Among these patients, 27 were diagnosed with HVI using CT, and 38 patients were diagnosed with HVI in the operating room. The median injury severity score for these patients was 10.0, the revised trauma score was 7.841, and the trauma injury severity score was 0.96. The sensitivity and specificity of CT in predicting HVI in these patients were 65.8%, and 96.0%, respectively. The positive and negative predictive values were 92.6%, and 78.7%, respectively.Conclusion: In urgent situations, CT findings alone are insufficient for diagnosing HVI. Further research on the HVI diagnostic capacity of CT is required.
Transsplenic Ultrasound-Guided Balloon Positioning During a Zone 1 Resuscitative Endovascular Balloon Occlusion of the Aorta: A Case Report
Authors: Heo Yoonjung , Chang Sung Wook , Kim Dong Hun
Published: March 2022

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an effective resuscitative modality to temporize noncompressible truncal hemorrhage. Confirming the proper position of the balloon catheter in the target aortic zone is vital. Currently, there is a need for nonradiographical methods. This would overcome the drawbacks of conventional imaging modalities, such as fluoroscopy. Several studies have suggested ultrasound-guided visualization via subxiphoid, transperitoneal, or transesophageal views as an alternative to conventional imaging methods. However, such views are easily obscured in emergency settings. Herein, we report the case of a 70-year-old patient who was successfully resuscitated by REBOA under the guidance of transsplenic ultrasound. REBOA was safely performed using transsplenic visualization without fluoroscopy.
The Occurrence of a Thyroid Storm in a Patient with Recurrent Refractory Peptic Ulcer: A Case Report
Authors: Park Kwanhoon , Jang Ji Young , Lee Sungho
Published: March 2022

A thyroid storm is a rare complication of hyperthyroidism. Although a thyroid storm rarely presents with symptoms similar to those of an acute abdomen, and in cases where emergency surgery is needed, the thyroid function test is not performed routinely. In this study, we report a case in which hyperthyroidism was diagnosed after surgery in a patient with recurrent refractory peptic ulcer disease. Although peptic ulcer disease and hyperthyroidism rarely coexist, when the patient's initial condition was reviewed in the Emergency Department, the findings were reasonable for panperitonitis due to peptic ulcer perforation, which is considered as a condition suitable for a thyroid storm. This isolated case indicates a logical leap in the correlation between peptic ulcer and thyroid storm. In recurrent refractory peptic ulcer disease, the thyroid function test may be helpful as a routine laboratory test before emergency surgery.
An Innovative Approach for Lesson Improvement through Collaboration
Authors:   the Faculty of Education, Chiba University, 1-33 Yayoi Inage, Chiba 263-8522, Japan, Kubota Tomomi , Yoshida Masami
Published: March 2022

This study proposes a method for improving lesson revision using the analytical hierarchy process (AHP), which is a structured technique for organized group decision-making. As a fundamental pedagogical principle of the proposed lesson improvement approach, we utilized collaborative action research theory, which involves applied action research, and focused on group-based lesson improvement. Furthermore, this study demonstrates a practical method that enables the incorporation of diverse assessment opinions from itinerant supervisors of educational boards to flow into a common conclusion to improve the lesson. We simulated a discussion case that involves informational avoidance actions. The consistency index of AHP could promote group decisions by presenting scores of consistency value across decision scenes. Furthermore, we present the effect of this method, in which a group produced a written document to transfer the record of the discussion process. This study is the first to illustrate the improvement of lesson design through collaboration among individuals with varied areas of expertise.

La hojarasca que se acumula sobre el piso forestal y su posterior descomposición juegan un papel importante en el mantenimiento de la productividad de los diferentes ecosistemas terrestres al constituir el principal flujo de nutrientes al suelo. El objetivo del estudio fue evaluar la producción de hojarasca y retorno de nutrientes a través de la caída de la hojarasca y la eficiencia en el uso de macro-nutrientes. El estudio se realizó en los sitios de Linares, Crucitas y Los Ramones, en el Estado de Nuevo León, México. El promedio de caída de hojarasca fue de 5 800, 5 270 a 6 596 kg ha−1 año−1 para Linares, Crucitas y Los Ramones, respectivamente. El retorno total de nutrientes siguió la secuencia: Linares >Crucitas >Los Ramones con valores de 135, 122 y 101 kg ha−1 año−1, respectivamente. A pesar de que el retorno de P en la hojarasca fue menor, la eficiencia del uso de este nutriente fue mayor que la presentada por el Ca, Mg ó K. La mayor eficiencia de uso de nutrientes en términos de Ca y Mg se observó en Los Ramones, el K en Crucitas y el P en linares. Existe variación espacial y temporal en la producción de hojarasca, retorno de nutrientes y la eficiencia en su uso entre los sitios evaluados. Por tanto, la caída de hojarasca, retorno de nutrientes y uso eficiente en estos sitios dependen de la riqueza de especies, diferencias edáficas, calidad de la hojarasca y fenología de las diferentes especies.

A imitação da linguagem na música de Khôra
Authors: Costa Silva José Eduardo
Published: March 2022

O presente artigo traz uma reflexão filosófica sobre a relação entre retórica e música à luz dos conceitos de Khôra e mimese, tal como estabelecidos por Platão, Derrida e Heidegger. Assim, esta reflexão é orientada por procedimentos metodológicos dialógicos e também por procedimentos fenomenológicos, sobretudo quando incide diretamente sobre as obras de arte. Ela tem como objeto de observação exemplos da música para alaúde praticada na França do século XVII, particularmente prelúdios e danças de J. Gallot (1625-1695), François Dufaut (1604-1672) e Johann Gottfried Conradi (†1747), os quais, em seu tempo, foram identificados por seus autores e editores como obras de retórica. A articulação entre conceitos, método e objeto permite deslocar a reflexão sobre a retórica musical para um âmbito mais amplo e originário, qual seja, o âmbito das reflexões sobre as relações entre música, linguagem e ser, ampliando e sustentando, desse modo, o campo de abertura para a investigação do tema abordado.

La ansiedad se evaluó con medidas fisiológicas, neuropsicológicas (escala STAI), y la intervención con autoinformes y registro de sesiones. El grupo mostró disminución en las medidas fisiológicas (presión arterial y pulso) y en la ansiedad rasgo. Los hallazgos proporcionan evidencia sobre la viabilidad y efecto de un programa MTFO estructurado y basado en sistemas teóricos fuertes.
O conceito de escolas de violino e sua atual aplicabilidade no Brasil
Authors: Reis Adonhiran , Held Marcus
Published: March 2022

O presente artigo discute a aplicabilidade do conceito de escolas de violino, outrora influentes, no Brasil de hoje. A partir de uma pesquisa que coletou dados de 110 violinistas residentes no país, foi constatado que expressiva fração dos participantes se declarava inserida em alguma escola de violino, como franco-belga, alemã ou russa. No entanto, a maioria absoluta também afirmava possuir em sua formação elementos oriundos das mais variadas fontes de aprendizado, incluindo diversos professores com visões técnicas, musicais e interpretativas distintas. Posto isto, buscamos então entender o que de fato constituiria uma escola de violino, para que possamos refletir sobre a real validação de vertentes oitocentistas na contemporaneidade brasileira globalizada. Por meio de revisão bibliográfica e questionário direcionado ao nosso público-alvo, tratamos o assunto sob as perspectivas histórica e pedagógica. Procuramos demonstrar que reduzir a noção de escola de violino a critérios técnicos e mecânicos, desvinculados de aspectos estilísticos associados a valores estéticos pregressos, não sustenta um sistema que seria hermético em si mesmo.
“Funk não é música”: faces da diferença, diversidade e discriminação
Authors: Coutinho Paulo , Rocha Inês
Published: March 2022

O funk como expressão musical se constitui em um contrassenso binário entre o seu apogeu midiático e, ao mesmo tempo, o imaginário social discriminatório atribuído por heranças preconceituosas que se perpetuam no horizonte da vida social das pessoas. A expressão “funk não é música” é facilmente ventilada em uma roda de conversa entre amigos e, muitas vezes, naturalizada pelo senso comum. Tal expressão é o mote deste estudo, que busca propor uma reflexão sobre o valor discriminatório atribuído ao funk, entendendo tal fenômeno como elemento indispensável nas discussões sobre práticas de ensino diante da diversidade em música. Para esta reflexão, buscamos suporte teórico em estudos do campo da educação e cultura e do campo da educação musical em suas interfaces com a etnomusicologia. O estudo contou, como procedimento de coleta de dados, com a observação de aulas e o uso de entrevistas semiestruturadas com cinco estudantes e dois professores de música que participaram deste estudo. A análise crítica dos dados, apresentada ao longo de duas seções no presente texto, problematiza as formas como o funk atravessa o imaginário social cotidiano, a partir das narrativas dos participantes do estudo. Nas considerações, apontamos questões que podem se tornar pontes reflexivas para pensarmos a complexidade da diversidade musical como fenômeno inerente à sala de aula e, ao mesmo tempo, problematizarmos diversidade e diferença como conceitos fundamentais para pensarmos práticas educativo-musicais contemporâneas.
O egresso de Música como fonte de informação: revisitando o passado, refletindo o presente, planejando o futuro
Authors: Weidner Keroll , Biaggi Emerson
Published: March 2022

A pesquisa com alunos egressos mostra-se em crescente desenvolvimento nas últimas décadas. É, porém, ainda incipiente e heterogênea a organização para o acompanhamento, levantamento e análise de dados advindos destes. Este artigo tem como objetivo principal delinear caminhos da pesquisa com o aluno egresso de Música, bem como apresentar e reforçar justificativas que fundamentam acompanhá-lo em sua trajetória profissional após a saída da universidade. A partir de revisão bibliográfica sobre o tema, foram identificadas possíveis estratégias de acompanhamento, como os portais institucionais e as pesquisas científicas específicas. A partir da pesquisa documental, com análise de conteúdo comparativa de três investigações específicas, reforçam-se a importância e a riqueza de informações às quais se pode ter acesso nesse campo investigativo. É razoável afirmarmos que uma das funções da universidade está diretamente vinculada à preparação e construção do profissional que atuará na (e para a) sociedade após sua graduação, e é dentro desse complexo cenário que a pesquisa e o acompanhamento de alunos egressos podem se mostrar ferramentas fundamentais.
Práticas musicais conectadas: bandas militares no “longo século XIX” e a banda de música da Força Policial Militar do Ceará
Authors: Gonçalves Inez
Published: March 2022

As últimas décadas do século XVIII sofreram modificações políticas e culturais que influenciaram o aumento do número de músicos militares em escala global. Dentre essas modificações, destacam-se a valorização dos regimentos do Exército como integrantes da autoridade do Estado e o declínio dos modelos de patrocínio e aprendizagem musical de origem aristocrática. De 1770 até o início da Primeira Guerra Mundial, observa-se uma grande difusão das bandas militares ao redor do mundo (HERBERT; BARLOW, 2013: 2. WHITWELL, 2010: 267). Os conjuntos que se instituíram nos regimentos militares nesse período apresentaram práticas que se conectaram, ultrapassando suas fronteiras nacionais. O presente artigo tem por objetivo analisar o surgimento das bandas militares na Europa e no Brasil e das práticas adotadas por esses grupos, principalmente a partir da história sociomusical da banda de música da Força Policial Militar do Ceará. Serão abordados temas como a responsabilidade dos militares no patrocínio da música no século XIX, a aprendizagem musical que se organizou no interior das instituições militares, a contratação de músicos civis para as bandas, as formas de pagamento dos músicos e os contratos estabelecidos para tocar em eventos não militares. O artigo conclui que as práticas vivenciadas nas bandas militares em nível local conectaram-se a dinâmicas globais mais amplas.
Permanência e transformação no terceiro movimento da Sonata Op. 109 de Beethoven
Authors: Monteiro Eduardo , Aguilar Pedro
Published: March 2022

O objetivo deste trabalho é, primeiramente, apontar relações entre tema e variações no último movimento da Sonata Op. 109 de Beethoven. Essas conexões, muitas vezes, não são evidentes e operam em um nível mais profundo do que o da melodia ou da harmonia. Também são apresentadas considerações sobre a interpretação pianística desta obra, sendo alguns desses apontamentos diretamente relacionados ao processo de análise. O trabalho se inicia contextualizando a sonata dentro da estética da fase tardia do compositor, o que foi importante para embasar algumas das conclusões obtidas. Em seguida, as variações foram estudadas individualmente, revelando relações locais e entre cada variação e o tema. Ao final, os resultados serviram de base para estabelecer conexões entre as variações e seu papel dentro do movimento como um todo.
The preparation of music teachers in Brazil and England: reflections on teaching practice models
Authors: Soares José , Welch Graham
Published: March 2022

This paper examines and compares teaching practice models of three music teacher training courses originating from Brazil and England, as well as addressing issues regarding the initial preparation of the music teacher in both countries. Activity theory was employed as a theoretical framework to explain the related factors involved in both models’ implementation. A number of challenges were indentified such as: (i) how to balance the theoretical and practical dimensions of the curriculum; (ii) the quest for mechanisms for the transferral of the pedagogical and musical instrument knowledge acquired by students to music teaching practice contexts; and (iii) the absence of a specialist music teacher as mentors in some educational contexts. Findings showed that there is diversity in teaching practice models due to different educational and technological contexts employed.

Published: March 2022

Through the nursing of a patient with Vogt Koyanagi-Harada syndrome with nystagmus, the nursing experience was summarized to make the nursing staff more fully understand the nursing methods of the patient with Vogt Koyanagi-Harada syndrome. Through comprehensive risk assessment of the patient, nurses formulate solutions, carry out nursing intervention, establish the patient's confidence and improve the patient's consciousness of medication. There were no complications during hospitalization, and preventive medication was still used according to the doctor's advice after discharge. At present, glucocorticoid is still the main drug for the treatment of Vogt Koyanagi Harada syndrome. The early sufficient treatment effect is good. Nurses can improve the drug compliance of patients adhering to formal treatment through effective nursing intervention, which can effectively prevent complications and significantly reduce disease recurrence.

The paper presents the results of studies of diamonds from Early Jurassic sediments making up the Nyurbinskoe buried placer of the Nakyn kimberlite field, unique in diamond reserves. The main task is to identify diamond distribution patterns in the deposits of the Dyakhtar Stratum (lower deposit) and the Ukugut Suite (upper deposit) within the placer. A comparative analysis of the typomorphic features of diamonds from the upper and lower deposits of the placer was carried out. Variations in the contents of crystals with certain properties that form the image of a diamond-bearing geologic object have been revealed. The zonal distribution of diamonds by characteristics in sedimentary deposits, regardless of their age, has been established. The properties of diamonds and their associations change within the placer, which is due to their redeposition during the Early Jurassic sedimentation.
Stages of Paleoarchean to Paleoproterozoic Basic–ultrabasic Magmatism in the Sarmatian Craton

The early stages of basic–ultrabasic magmatism in Sarmatia are characterized by the appearance of ultrabasic rocks formed from the mantle with an abnormally high iron content. Therefore, it is important to study them as the source of information about the stages and causes of the activity of the mantle and its possible composition. This magmatism has been recorded in Sarmatia since the beginning of the Eoarchean. The relics of Eo- and Paleoarchean basic and ultrabasic rocks were found in the Dniester–Bug, Kursk, and Azov provinces, which underwent tectonic reconstruction in the Mesoarchean and Paleoproterozoic. Mesoarchean basic–ultrabasic magmatism is manifested in all provinces of Sarmatia and is represented by effusive and intrusive facies. The Mesoarchean greenstone belts composed of komatiites and basalts have been well preserved in the Middle Dnieper province; in other provinces, they are strongly deformed and form narrow linear structures. The Paleoproterozoic endogenous activity in Sarmatia differs from that in other regions in the almost complete absence of magmatism in the period 2.5–2.3 Ga and its significant manifestation 2.1–2.0 Ga. The magmatism in Sarmatia at this stage is similar in the ratios of basic–ultrabasic and granitoid complexes to the magmatism in South Africa but differs from that in Fennoscandia and Canada. The volume of granitoids coeval with basic rocks is larger than the volume of mantle magmatism. The igneous complexes formed 2.1–2.0 Ga in Sarmatia and South Africa are also similar in the presence of norites, the enrichment in Ni and platinum group elements, and the ratio of granitoids and basic–ultrabasic rocks. Magmatic activity (first of all, basic–ultrabasic magmatism in ancient cratons) is not a synchronous phenomenon on a planetary scale and varies greatly in the volume of produced material within the same time intervals. Early Precambrian basic–ultrabasic rocks (volcanics of greenstone belts, intrusions of large igneous provinces, and layered massifs) resulted from plumes, whose derivates formed within the lower and upper mantle and/or the upper mantle and crust, which determined the heterogeneous composition of igneous rocks. The spatial heterogeneity and nonsynchronic occurrence of basic–ultrabasic magmatism might have been due to impact events serving as the triggers of plumes.

—We have studied the mineral composition of ores from the Pepenveem epithermal Au–Ag deposit, which is a promising new object of the Chukchi Peninsula. It has been found that the ore formation process was developed in the following sequence: Pyrite, arsenopyrite, and marcasite were deposited at the early stage, next were Pb, Zn, and Cu sulfides; at the late stage, native gold, pyrargyrite, stephanite, proustite, minerals of the pearceite–polybasite series, acanthite, and other Ag minerals were deposited. The results of fluid inclusion studies indicate that the Au–Ag mineralization formed from low-temperature (236–137 °C) low-concentration chloride hydrotherms (0.18–1.57 wt.% NaCl eq.). The results of calculation of thermodynamic equilibria have shown that in the temperature range from 200 to 100 °C, there were a decrease in the fugacity of sulfur (lg fS2 from –10 to –21) and oxygen (lg fO2 from <–36 to <–48) and a change from near-neutral to acidic solutions. Compared to other Au–Ag deposits on the Chukchi Peninsula (Corrida and Valunistoe), which are characterized by wide distribution of Se- and Te-bearing Au–Ag chalcogenides (naumannite, cervelleite, and hessite), ore formation with gold–silver–sulfosalt mineralization at the Pepenveem deposit took place at lower temperatures and lower selenium, tellurium, and oxygen fugacity. The data obtained permit us to refer the Pepenveem deposit to the group of epithermal low-sulfidation (LS) deposits.
