Kintsugi 100 (sem) memórias: o gesto autoficcional performativo para o encontro com a dramaturgia da memória
Authors: Baldo Lysiane Cassia , Da Silva Acir Dias
Published: May 2021

O ponto de partida se dá pelo diálogo entre um alargamento do conceito de ‘dramaturgia’ exercitado em experimentações cênicas contemporâneas, colocado em relação a espetáculos que têm como mote a investigação da memória do ator/performer em uma perspectiva autoficcional. O trabalho sobre o “eu” e a evocação das memórias é evidenciado como procedimento de criação de um teatro performativo. Com base nestes pressupostos e, tomando como objeto um trabalho artístico de relevância nesta temática e referência nas artes da cena, o objetivo é compreender como a dramaturgia da memória se constrói no processo de criação do espetáculo Kintsugi: 100 (sem) memórias (2019) do Lume Teatro. Para tanto, os seguintes questionamentos são levantados: Sob quais perspectivas a memória é configurada nesta obra? Como os limites entre o “real” e o ficcional são definidos nos processos de criação neste trabalho cênico? A metodologia empregada é a da literatura comparada, na análise texto/cena/performatividade com vistas ao processo de composição. A base teórica se delimita principalmente nos seguintes autores: Eco, Borriaud, Lopes e nos relatos da atriz Ana Cristina Colla em entrevista nesta pesquisa elaborada, entre outros. Como resultado, constatamos que a 'memória criadora' aliada à performatividade fricciona as fronteiras real/ficcional, redimensionando a cena e a dramaturgia contemporâneas.

Wetlands constitute areas with significant value and service offerings both in anthropogenic and natural environments. Taking into consideration the importance of studying wetland ecosystems and their changes, the aim of this paper is the observation of Lake Karla’s reservoir fluctuation, since its reconstitution in 2010. For this reason, annual and seasonal fluctuations of the reservoir were estimated, utilizing remote sensing Synthetic Aperture Radar (SAR) (Sentinel 1) and optical (Sentinel 2) imagery, as well as Landsat 5 imagery. For SAR imagery an image segmentation method with a dynamic threshold operator based on mean values is utilized, while for optical imagery the Normalized Difference Water Index (NDWI) is applied. The findings reveal changes in Karla’s reservoir, with its acreage being continually increased on average on an annual basis. Meanwhile, on a seasonal basis, the results indicate some variations in the reservoir, due to precipitation and irrigation purposes.

Risk Factors of Carbapenem-Resistant Enterobacteriaceae Infection and Colonisation: A Malaysian Tertiary Care Hospital Based Case-Control Study
Authors: Chuah Chuan Huan , Gani Yasmin , Sim Benedict , Chidambaram Suresh Kumar
Published: May 2021

Background

Carbapenem-resistant Enterobacteriaceae (CRE) infection has become a major challenge to clinicians. The aim of this study is to identify the risk factors of acquiring CRE to guide more targeted screening for hospital admissions.

Methods

This is a retrospective case-control study (ratio 1:1) where a patient with CRE infection or colonisation was matched with a control. The control was an individual who tested negative for CRE but was a close contact of a patient testing positive and was admitted at the same time and place. Univariate and multivariate statistical analyses were done.

Results

The study included 154 patients. The majority of the CRE was Klebsiella species (83%). From univariate analysis, the significant risk factors were having a history of indwelling devices (OR: 2.791; 95% CI: 1.384-5.629), concomitant other MDRO (OR: 2.556; 95% CI: 1.144-5.707) and hospitalisation for more than three weeks (OR: 2.331; 95% CI: 1.163-4.673). Multivariate analysis showed that being unable to ambulate on admission (adjusted OR: 2.345; 95% CI: 1.170-4.699) and antibiotic exposure (adjusted OR: 3.515; 95% CI: 1.377-8.972) were independent predictors. The in-hospital mortality rate of CRE infection was high (64.5%). CRE acquisition resulted in prolonged hospitalisation (median=35 days; P<0.001).

Conclusion

CRE infection results in high morbidity and mortality. On top of the common risk factors, patients with mobility restriction, prior antibiotic exposures and hospitalisation for more than three weeks should be prioritised in the screening strategy to control the spread of CRE.
Hypnale Coagulopathy: Snake Envenomation of a Different Kind
Authors: Naik Bolar Sadananda
Published: May 2021

Hypnale hypnale is a small pit viper that is known as the hump-nosed pit viper (HNV) or ‘Merrem's hump-nosed pit viper’ and is endemic to Sri Lanka and the Western Ghats of South India. Previously, it was thought that this viper bite would result in mild systemic or local envenomation, however, we now know that HNV bites could cause severe systemic toxicity and mortality. The most common systemic toxicity of this viper envenomation is coagulopathy, which is known as ‘Hypnale coagulopathy'. Hypnale coagulopathy is quite different from the haemotoxicity caused by other vipers. In this paper, an effort has been made to discuss the unique and unpredictable nature of this coagulopathy due to Hypnale envenomation.
Epstein-Barr Virus and Acute Liver Failure: An Exceedingly Rare Amalgamation
Authors: Kamal Tom , Haboubi Nadim
Published: May 2021

Epstein-Barr virus (EBV) associated acute liver failure (ALF) is an exceedingly uncommon event. Despite this, EBV-associated ALF has a very high fatality rate. When looking at the number of reported cases of EBV-associated ALF requiring an emergency liver transplant, we see even fewer numbers. This presents challenges to clinicians in the diagnosis, awareness and appropriate case management. There is limited information in the medical literature about the hepatic demonstration and complications of EBV. We therefore report a case of EBV-associated ALF in a 17-year-old immunocompetent female who was treated successfully with an orthotopic liver transplantation.

Published: May 2021

Amiodarone is a common medication used widely in clinical practice. It is a triiodinated antiarrhythmic associated with a variety of adverse effects both pulmonary and extrapulmonary, the most serious being amiodarone-induced pulmonary toxicity (AIPT) or amiodarone lung. This can present with a variety of clinical syndromes ranging from subacute symptoms to an indolent and a progressive course thus mimicking an alternative diagnosis.

We report a case of amiodarone lung in a female who presented with an acute fulminant progressive pneumonitis despite being on very low dose (100 mg once daily) that proved fatal. Diagnosis was made on postmortem examination due to a diagnostic conundrum. Despite the steady decrease of AIPT with reduced dose, it is vital for the treating clinicians to monitor regularly for adverse effects and review the need for long-term use to prevent complications.

Introduction

Linum usitatissimum seed or flax seed is known as a potential candidate as a remedy to treat various diseases in many traditional medicines around the world. In the current study, the antioxidant, cytotoxicity, and anti-human lung cancer properties of Linum usitatissimum seed were investigated in in vitro conditions.

Material and methods

Antioxidant activity of the plant was analyzed using radical scavenging activity and ferrous ion chelating assay. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay was used to evaluate anti-lung cancer properties of the plant.

Results

The plant extract scavenged 2,2-diphenyl-1-picrylhydrazyl (DPPH) as a free radical with an IC50 of 34.2 ±0.9 µg/ml. The plant was also found to be rich in phenolic compounds with 294.8 ±2.3 mg GAE/g for total phenolic content. Cell viability of Linum usitatissimum seed was very low against lung poorly differentiated adenocarcinoma (PC-14), lung moderately differentiated adenocarcinoma (LC-2/ad), and lung well-differentiated bronchogenic adenocarcinoma (HLC-1) cell lines without any cytotoxicity towards the normal cell line. The best anti-human lung cancer properties of Linum usitatissimum seed against the above cell lines were observed in the case of the PC-14 cell line. According to the above findings, Linum usitatissimum seed may be administered for the treatment of several types of human lung cancer in humans. According to the results, the IC50 values of plant extract against lung poorly differentiated adenocarcinoma (PC-14), lung moderately differentiated adenocarcinoma (LC-2/ad), and lung well-differentiated bronchogenic adenocarcinoma (HLC-1) cell lines were found to be 392, 483, and 564 µg/ml, respectively.

Conclusions

It appears the recent formulation can be used as a novel chemotherapeutic supplement in humans.

Colour image segmentation using perceptual colour difference saliency algorithm
Authors:   , Bukola Taiwo Tunmike
Published: May 2021

The topic of colour image segmentation has been and still is a hot issue in areas such as computer vision and image processing because of its wide range of practical applications. The urge has led to the development of numerous colour image segmentation algorithms to extract salient objects from colour images. However, because of the diverse imaging conditions in varying application domains, accuracy and robustness of several state-of-the-art colour image segmentation algorithms still leave room for further improvement. This dissertation reports on the development of a new image segmentation algorithm based on perceptual colour difference saliency along with binary morphological operations. The algorithm consists of four essential processing stages which are colour image transformation, luminance image enhancement, salient pixel computation and image artefact filtering. The input RGB colour image is first transformed into the CIE L*a*b colour image to achieve perceptual saliency and obtain the best possible calibration of the transformation model. The luminance channel of the transformed colour image is then enhanced using an adaptive gamma correction function to alleviate the adverse effects of illumination variation, low contrast and improve the image quality significantly. The salient objects in the input colour image are then determined by calculating saliency at each pixel in order to preserve spatial information. The computed saliency map is then filtered using the morphological operations to eliminate undesired factors that are likely present in the colour image. A series of experiments was performed to evaluate the effectiveness of the new perceptual colour difference saliency algorithm for colour image segmentation. This was accomplished by testing the algorithm on a large set of a hundred and ninety images acquired from four distinct publicly available benchmarks corporal. The accuracy of the developed colour image segmentation algorithm was quantified using four widely used statistical evaluation metrics in terms of precision, F-measure, error and Dice. Promising results were obtained despite the fact that the experimental images were selected from four different corporal and in varying imaging conditions. The results have indeed demonstrated that the performance of the newly developed colour image segmentation algorithm is consistent with an improved performance compared to a number of other saliency and non- saliency state-of-the-art image segmentation algorithms.

Protecting the Public and Our Physicians' Interests: A Proposal to Rectify Inconsistencies and Develop Guidelines on Physicians' Disclosure of Patients' Health Data to Third Parties in Thailand
Authors: Direksoonthorn Khajorndej
Published: May 2021

This article argues for law reform in Thailand concerning the protection of health data, particularly laws involving the data’s disclosure to third parties. It has been found that several pieces of Thai legislation governing this area are conflicting, causing confusion and disquiet to Thai physicians. Recently, Parliament has enacted the Personal Data Protection Act 2019. The said GDPR-style Act should have clarified all already-existing confusion regarding the inconsistency of legislation, but it has further complicated the matter instead. Doctors cannot disclose patients’ health data to third parties, even to protect others or public interests. Court cases from other jurisdictions show that courts are willing to impose on physicians the duty to disclose patients’ health data to third parties under certain circumstances, which makes the issue more significant to the Thai legal and medical communities. The article provides proposals to rectify the issue by amending relevant statutes and calling for professional guidance on this area which should be addressed by pertinent legislation. The relevant professional guidelines alongside the amended legislation will serve the interests of medical professionals, patients, and society at large.

Published: May 2021

Along with other diagnostic methods, all current recommendations and protocols for malignant tumors’ diagnostics and treatment require mandatory molecular genetic testing at the initial diagnosis and in case of disease progression.

The discovery of the BRAF gene mutation in skin melanoma allows the treatment with tyrosine kinase inhibitors, so-called BRAF inhibitors. This increases the probability of tumor response by half and opens up new therapeutic options.

The study aimed to identify the BRAF V600E gene mutation frequency in patients with stage III-IV melanoma in the Republic of Kazakhstan to determine the need for targeted therapy.

Results: 2251 persons are currently registered with melanoma in the Republic of Kazakhstan, with 355 new primary melanoma cases in 2019. Of them, 54% were diagnosed at stages III-IV and were subject to molecular genetic testing. 278 of 2251 patients were sent for BRAF mutations testing. The mutations were detected in 105 (37.7%) patients.

Conclusion: The introduction of molecular genetic testing for malignant neoplasms under the Comprehensive Cancer Control Plan framework for 2018-2022 will increase the use of molecular genetic methods in the Republic of Kazakhstan. Molecular genetic testing is an important step in diagnosing melanoma and choosing the appropriate therapy to personalize cancer treatment.

Timely determined treatment tactics, taking into account the tumor localization and possible postoperative complications, led to tumor remission. At present, the patient is under dynamic observation.

Conclusion: The presented clinical case confirms that a primary nasal cavity Ewing’s sarcoma diagnostic largely depends on histopathological examination since visual diagnostic techniques do not provide reliable information on the tumor type.

Radiation therapy is one of the leading methods of treating malignant tumors of female genital organs. However, modern radiotherapeutic equipment technical capacity does not exclude the possibility of radiation complications from healthy organs and tissues in the radiation zone. During radiation treatment (administered independently or in combination with other methods), patients develop local radiation reactions of different intensity from related organs, such as the bladder, rectum, and vagina, which significantly deteriorate patients’ quality of life. This also leads to involuntary interruptions in treatment and, finally, worsens the treatment outcome.

Purpose: To describe radiation injuries to pelvic organs in cervical cancer radiation treatment. It analyzes the frequency and evidence of early and late radiation reactions from the affected organs.

Results: Radiation injuries to the pelvic organs form the basis of radiation pathology in patients with cervical cancer and largely determine cured patients’ quality of life. Radiation complications of grade II-III, less often IV, are frequent after radiation treatment for pelvic cancer, especially cervical cancer.

Conclusions: Despite the improvements in radiation treatment methods, there is still no unified system for preventing radiation reactions that would include algorithms for diagnosing and treating early and late radiation reactions using modern medications and non-pharmacological options. The development and implementation of an algorithm for the correction of radiation reactions after radiation and complex treatment for cervical cancer would timely prevent radiation and combined complications from target organs and improve patients’ quality of life.
Is Endoscopic Submucosal Dissection (ESD) Ready for Primetime in North America?
Authors: Abdelfattah Thaer
Published: May 2021

Endoscopic submucosal dissection (ESD) is a novel technique for endoscopic en bloc resection of neoplastic and dysplastic lesion in the gastrointestinal tract. Endoscopic Mucosal Resection (EMR) has been used historically however ESD carries the added advantage of providing accurate histopathologic evaluation for resection margins, low recurrence rate, curative resection. Also compared to surgery it carries a lower risk of morbidity and mortality. ESD is well established in Asia however its adoption is lagging in North America.
We summarize the @GIJournal discussion held on March 10th, 2021 during which Draganov et al. “Endoscopic Submucosal Dissection (ESD) in North America: A Large Prospective Multicenter Study” was critically reviewed by our expert panel: Drs. Neil Sharma (NS), and Mohamed Othman (MO) and moderated by Dalbir Sandhu (DS).
José de Alencar: Insights sobre a acomodação tensa entre tradição e modernidade no Brasil
Authors: Nascimento Márcio Luiz do , Pfeffer Renato Somberg , Motta Carolina Portugal Gonçalves da , Araújo Ana Luísa Gomes de
Published: May 2021

O presente trabalho analisa a acomodação eivada de tensões entre o fenômeno patrimonialista e o modelo burocrático-capitalista no final do século XIX no Brasil a partir de insights contidos na obra Senhora (1875) de José de Alencar. Em um primeiro momento, o artigo analisa as interpretações do Brasil sob a ótica weberiana para, em seguida, discutir o processo de acomodação entre tradição e modernidade no contexto histórico do Império brasileiro contidos nessa obra do romancista. A hipótese que norteia o texto assenta-se na ideia de que o patrimonialismo, presente no Brasil desde o período colonial, atingiu o ápice de sua influência e um elaborado processo de acomodação com a ordem racional-legal durante o Império. José de Alencar retrataria nos personagens e no enredo da referida obra os elementos dessa acomodação e sua oposição ao avanço da ordem burguesa sobre a ordem patrimonialista.
A banalidade do mal à luz da sociologia - Considerações sobre a razão militar
Authors: França Fábio
Published: May 2021

Objetivamos neste artigo, a partir de uma discussão teórica, refletir sociologicamente sobre o fenômeno da banalidade do mal, conceito cunhado por Hannah Arendt. Para tanto, voltamos nosso olhar especificamente para a razão militar e seus mecanismos, especialmente o princípio da obediência, de modo a refletirmos não apenas sobre a presença da autoridade em fenômenos como a banalidade do mal, mas também para compreendermos processos de socialização que têm por objetivo a naturalização da violência.
O mercado de games: Gênese, transformações e tendências
Authors: Toyama Miriam Costa , Ferratti Gustavo Mendonça , Côrtes Mauro Rocha
Published: May 2021

Games fazem parte da indústria cultural multibilionária, possuindo, portanto, relevância econômica e social. Neste ensaio, buscamos realizar uma sociogênese da indústria de games, ancorada nos conceitos de espaço social e campo, a partir de diversos autores, com destaque para Pierre Bourdieu. Com recorte temporal, feito entre os anos 1940 até o momento atual, início da segunda década do século 21, mostramos o fato de que esse espaço social vem sendo reconfigurado, devido às inovações advindas de campos sociais vizinhos, como os da indústria de eletroeletrônicos, informática, telecomunicações e jogos de azar. Tais reconfigurações implicam em rearranjos de posições de agentes, criação de estruturas institucionais e estabelecimento de relações sociais diversas. Por fim, tecemos as considerações pertinentes ao futuro dessa indústria.
Notas sobre a sociologia da ação e a ética protestante e o espírito do capitalismo
Authors: Targino Janine
Published: May 2021

A sociologia da ação, também chamada de sociologia interacionista ou acionista, refere-se a uma perspectiva que se afasta das definições que contemplam as atividades dos atores sociais e suas representações como meras manifestações do funcionamento do sistema. Dessa forma, vemos na sociologia da ação o comprometimento com a construção de um entendimento sobre as razões que levam os atores sociais a fazer o que fazem ou a acreditarem naquilo que acreditam. Deve-se sublinhar que o individualismo metodológico constitui o princípio fundamental da sociologia da ação. Neste artigo trataremos especificamente sobre como a sociologia da ação nos serve de norteadora para analisarmos a relação existente entre a ascese protestante e o desenvolvimento do capitalismo no Ocidente. Tal relação, tratada com bastante propriedade por Max Weber, nos revela que transformações ocorridas na esfera econômica podem encontrar estímulo em outros domínios sociais como, por exemplo, a religião.

Nhồi máu hoại tử mạc nối là một nguyên nhân hiếm gặp gây đau bụng cấp do xoắn, tắc mạch mạc nối hoặc nhiễm trùng ổ bụng. Biểu hiện lâm sàng không đặc hiệu nên nhiều bệnh nhân được chỉ định mổ với chẩn đoán trước mổ là viêm túi mật, viêm ruột thừa hay thủng tạng rỗng. Với sự ra đời của chụp cắt lớp vi tính, nhồi máu mạc nối được chẩn đoán xác định nhiều hơn trước khi phẫu thuật. Chúng tôi báo cáo 2 ca lâm sàng nhồi máu mạc nối lớn vào viện vì đau bụng dưới sườn phải. Chụp cắt lớp vi tính có dấu hiệu thâm nhiễm, dày mạc nối. Hai bệnh nhân đều được mổ nội soi cấp cứu cắt bỏ phần mạc nối lớn bị nhồi máu, cả 2 bệnh nhân khỏi, ra viện sau 3 ngày điều trị. Kết luận: phẫu thuật nội soi ổ bụng nên được chỉ định vừa để chẩn đoán nguyên nhân, vừa điều trị cho kết quả tốt.

This exploratory study examines how a community experiencing food insecurity while navigating multiple crises can be a model to inform resources, processes, and systems supporting communities facing similar circumstances. Data for this study were collected from residents of a community in Oconee County, a rural county in the northwest corner of South Carolina experiencing pervasive food insecurity. The community was severely impacted by the onset of COVID-19 and further devastated by a tornado in mid-April. The area of the county that sustained the greatest damage from the tornado was the Utica Mill Hill community, home to the county’s most vulnerable population. This cascading series of events constituted a crisis-within-a-crisis for the community. In this study, we sought to learn more about community members’ experiences and the effects of the crises on com­munity members’ access to food. We conducted in-depth interviews with 14 residents living in the Utica Mill Hill community. The results provided insight into community members’ experiences of the crises and the nature of community-level response and recovery efforts. We learned about participants’ experiences with food insecurity, new food policy developments, and gained unexpected insight into community members’ experiences with mental health challenges related to the crises.
Chemical Variation in Coexisting Chromite and Olivine in Chromitite Zones of the Stillwater Complex
Authors: Jackson Everett D.
Published: May 2021

The chromitite zones in the Stillwater Complex consist of alternating chromite-rich and olivine-rich stratiform layers. On the basis of previous work, it was concluded that where olivine and chromite occur together as cumulus minerals, they formed as simultaneous crystallization products, in equilibrium with each other and the Stillwater magma. This hypothesis was tested in the present study by determining the proportions and compositions of 35 coexisting olivine and chromite pairs encountered in channel samples of the G and H chromitite zones in the Mountain View area. It was found that the cation fractions of Mg and Fe+2 in the chromite and olivine, and the cation fractions of Cr, Al, and Fe+3 in the chromite, are clearly related to the proportions of the two minerals in the 35 layers. The variations in these cation fractions were compared with theoretical variations expected on the basis of free energies of formation of end-member olivines and spinels. It was found that the observed and expected variations were of the same general magnitude and direction, and that the compositions of coexisting olivine and chromite in G- and H-zone layers can be accounted for by means of a simple thermodynamic model.

The regularity in concomitant chemical and volumetric variation of chromite and olivine is such that the grade of the chromite in any layer in the G and H zones can be estimated given only the local stratigraphic section and the proportions of chromite and olivine in the layers. Work is continuing on the possibility of using olivine-chromite pairs as relative geothermometers.
