O cosmos das línguas indígenas perante a barbárie do antropoceno
Authors: Gruber Gabriel , Miranda Emanuely
Published: June 2023

A emergência climática e os genocídios multiespécies nos levam a compreender este tempo como uma barbárie cósmica, decorrente de consecutivas colonizações. A cena científica experimenta nomeá-lo como Antropoceno. Este artigo se mobiliza a pensar a ligação entre linguagem e a percepção cósmica. Assim, por meio de reflexões do poder de supressão da monológica colonial sobre as onto-epistemologias das línguas indígenas americanas e a potência da soltura dos grilhões antropocênicos, propor um giro decolonial nas ciências e experiências de vida em busca de um futuro ancestral que possibilidade alternativas alheias aos caminhos do Antropoceno e garanta uma confluência de cosmos.

Authors: Lovatto Tatiana Quintana Samper , Sleiman Sumaia Abdallah
Published: June 2023

Este ensaio tem como objetivo geral discutir a forma como as práticas de violência institucional e de racismo ambiental impactam a vida de pessoas historicamente vulnerabilizadas, ao lançar luz sobre o cenário das favelas de Campo Grande - MS. A partir da revisão bibliográfica, nossa fundamentação se assenta nas leituras de Cutzen e Stoemer (2020) acerca da era do Antropoceno , nas proposições de Latour (2020) e sua concepção de Pluriverso, assim como nos estudos de pesquisadores latino americanos e suas críticas ao modelo de desenvolvimento e nos trabalhos de autores brasileiros sobre populações negra e tradicionais. Os dados apresentados indicam que a modernidade se articula em um discurso desenvolvimentista de progresso que tem causado danos à vida no planeta Terra. Ao final, tecemos críticas ao modelo de desenvolvimento, em busca de uma ampliação de espaços de escuta e de direitos.
EVALUASI KEGAGALAN STRUKTUR DINDING PENAHAN GRAVITASI PADA LERENG TANAH KOHESIF
Authors: Yuliet Rina , Hakam Abdul , Putra Hendri Gusti , Alfian Rifqi Luthfi
Published: June 2023

Stabilitas dinding penahan tanah (DPT) gravitasi sangat dipengaruhi oleh berat sendirinya. Jika masa tanah yang berada di belakang DPT adalah tanah kohesif, maka air yang berada di dalam retak tarik akan menyebabkan bertambahnya tekanan tanah lateral aktif. Dalam perancangan DPT gravitasi yang menahan tanah kohesif dengan kemiringan lereng yang curam, sering ditemukan nilai koefisien tekanan tanah yang tidak dapat didefinisikan akibatnya nilai tekanan tanah aktif tidak dapat dihitung. Untuk menganalisis stabilitas DPT digunakan persamaan Mazindrani dan Ganjali (1997) untuk perhitungan tekanan tanah aktif sesudah retak tarik. Dari hasil evaluasi stabilitas DPT diketahui bahwa dimensi dinding DPT eksisting memiliki nilai Faktor Keamanan (FK) lebih besar dari yang disyaratkan, dimana nilai FKguling = 2.5, FKgeser = 3, dan FKdaya dukung = 3. Penyebab kegagalan struktur DPT disebabkan kaena belum dilakukan kelanjutan pembangunan DPT pada bagian lereng yang curam yang berada dekat dengan DPT eksisting. Ketika hujan yang datang berkepanjangan menyebabkan terjadinya kelongsoran lereng dan menimbulkan kegagalan struktur DPT eksisting yang berada dekat dengan lereng yang longsor tersebut. Solusi yang tepat untuk mencegah terjadinya kegagalan struktur DPT eksisting adalah dengan melanjutkan pembangunan DPT pada bagian lereng yang longsor, memperbaikai drainase dan melakukan memotong lereng menjadi horizontal.

Around 9,800 Finns move abroad each year. Since the mid-1990s, temporary migration to Europe has become more common, but we know little of how this impacts the salary levels and careers of these temporary migrants when they return to Finland. This article uses cohort data, which includes a 10 percent random sample of Finnish citizens born in 1963, 1968, 1973, and 1978. We focus on migrants who return in 2005. The migrants have good labour market situations prior to leaving. Two years after return, the median income of the men is 2 times and the women 2.2 times higher when compared to earnings prior to migrating. Factors predicting lower incomes upon return to Finland include female gender, low income before migrating, leaving in any other labor market status than employed, and leaving already in the 1990s. A stay abroad does not signify a loss of labour market status, but is in fact economically beneficial: returnees earn more than Finns on average and the difference remains for 10 years. Such migrants are not pushed abroad by unemployment but are rather pulled by the opportunities available.

Wacana amandemen konstitusi muncul dengan usulan untuk menambah masa jabatan presiden menjadi 3 (tiga) periode. Upaya pembatasan atas wacana tersebut perlu dilakukan agar konstitusionalitas masa jabatan presiden tetap terjaga. Menghindari adanya hambatan-hambatan yang ada yang perlu diformulasi ulang dalam konstitusi Indonesia, maka perpanjangan kepemimpinan presiden hanya dibatasi sebanyak 2 (dua) periode. Pasalnya, jika amandemen kelima muncul, maka banyak hambatan yang terjadi pada sisi masyarakat, karena dianggap sebagai pematah semangat pejuang reformasi dalam melawan kekuasaan masa otoriter.
İŞ YAŞAMINDA E-KELEPÇE VE DİJİTAL MOBBİNG
Authors: TÜZÜN Perihan
Published: June 2023

Çalışma yaşamının değişen ve dönüşen yapısı gereği, iletişim kanallarının artışı ve küresel salgının (Covid-19) hızlandıran etkisiyle çalışanlar için gece-gündüz, hafta içi-hafta sonu kavramı neredeyse ortadan kalkmıştır. Bu durum yaklaşık 15- 20 yıl önce özel sektörde (çalışanlara tahsis edilen şirket telefonlarının akıllı telefon statüsüne dönüşmeye başladığında) daha yaygın olarak görülmekte iken günümüzde eğitimden ticarete kamu sektöründen özele kadar neredeyse tüm çalışma yaşamına yayılmış durumdadır. Yöneticilerin çoğunun bu süreci doğal karşılaması sonucu çalışanların büyük kısmının bu şekilde çalışmak istemedikleri halde adeta içine çekildikleri düşünülmektedir. Bu durum, dinlenme zamanları ve izinli olunan tarihlerde dahi iş yapmaya devam etmek zoruna hissedilmesi ve ilk başta stres olmak üzere birçok psikolojik ve fiziksel rahatsızlıkları oluşturabilecek bir potansiyele sahiptir. Mobbing olgusunun doğası gereği, sadece üstler tarafından değil, eşitler ve astlar tarafından yapılan mobbinge maruz kalan çalışanlar, iş baskısının haricinde, doğrudan kişiliklerini hedef alan olumsuz davranışlara maruz kalabilmektedir. Mobbingin dozunun her geçen gün artması ve farklı teknolojik araçların etkisiyle henüz yeni bir kavram sayılabilecek olan “dijital mobbing” kavramı ortaya çıkmıştır. Bu çalışma kapsamında, dijital mobbing konusu, çalışma şekillerinin değişmesi ile yaşanma şekillerinde ortaya çıkan değişiklikler bağlamında ortaya çıkan sonuçlar ile ilgili yurt içi ve dışı alan yazın incelenmiş ve konu ile ilgili çeşitli değerlendirmelerde bulunulmuştur.
Direito Antidumping. A anatomia de um privilégio
Authors: De Saules Nogueira Jorge Henrique , Salzer Procópio Thais
Published: June 2023

O artigo analisa a regulamentação internacional e doméstica do direito antidumping e apresenta suas consequências sob a ótica da teoria austríaca do intervencionismo econômico.  Dumping ocorre quando empresas de um país ofertam bens e produtos a outros países a preços inferiores aos praticados em seus próprios mercados domésticos. O conceito de dumping foi deturpado para acomodar interesses da indústria nacional. A aplicação de medidas antidumping pelo estado brasileiro implica a redução da exposição da indústria nacional à competição internacional e, por conseguinte, a oneração dos produtos e bens adquiridos pelos consumidores domésticos e pela indústria situada a jusante das cadeias produtivas. A análise de casos práticos de medidas antidumping implementadas no Brasil - como as aplicadas ao alho, aos sapatos chineses e ao ácido adípico - mostram que, além de distorcerem o mercado, as medidas deixam os produtos mais caros e prejudicam os consumidores e a sociedade.

Synthesis of dietanolamide surfactant from methyl ester of sunflower seed oil (Helianthus annuus. L) has been carried out through an amidation reaction. The synthesis process includes extraction, esterification and amidation. In the extraction process showed the oil content of sunflower seeds was 32.93% with an acid number of 3.25 mg KOH/g and ALB levels of 1.63%. Sunflower seed oil was then converted to methyl ester through the esterification process and obtained an acid number 1.84 mg KOH/g so that the ALB level dropped to 0.92% and obtained saponification numbers of 61.19 mg KOH/g. The most dominant composition of methyl ester of sunflower seed oil based on GC-MS analysis was methyl oleate at 23.28%. The FT-IR methyl ester spectrum gives a specific absorption peak for group C=O ester at wave number 1743 cm-1. Methyl esters are converted to diethanolamide through an amidation process. The resulting diethanolamide has an acid number of 9.7 mg KOH/g and a saponification number of 3.08 mg KOH/g. The FT-IR spectrum provides specific absorption peaks for groups C=O amides at wave numbers 1622 cm-1 and C-N at wave numbers 1055 cm-1. The value of HLB dietanolamide in practice is 13.6495 and in theory is 14.291 which includes the surfactant in the oil in water (O/W) emulsifying class.

Published: June 2023

Разработана рецептура ржано-пшеничного хлеба с введением нардека в качестве компонента, улучшающего качество готового продукта. Проведены исследования органолептических и физико-химических показателей полуфабрикатов и готового продукта. Замена патоки мальтозной на нардек оказывает влияние на показатели внешнего вида изделия за счет увеличения эластичности теста и ускоряет процесс замешивания. Наиболее заметный эффект достигнут при полной замене в рецептуре ржано-пшеничного хлеба патоки мальтозной и сахара на нардек при использовании жидкой ржаной закваски. Данная рецептурная композиция способствовала сокращению продолжительности замеса теста и заметному улучшению внешнего вида, эластичности мякиша, пористости, а также увеличивала удельный объем и сроки хранения готовых изделий. Внесение нардека в рецептуру дает возможность сохранить качество и увеличить сроки хранения готового продукта до 7 сут. (в 1,9 раза больше в сравнении с контрольным вариантом).

Published: June 2023

Aplicamos el método de convolución y correlación para buscar en una imagen de texto el número de veces que se repite una letra o una palabra, para ello ocupamos una máscara laplaciana para realizar una convolución entre esta mascara y las dos imágenes a tratar (la imagen que contiene todo el texto y la imagen de texto o letra que se quiera buscar), posteriormente aplicamos el método de correlación para obtener los valores máximos en ambas imágenes y hacemos un conteo al comparar los valores más altos a través de la imagen. La combinación de estas dos técnicas ha resultado muy útil en el tratamiento de imágenes para el reconocimiento de caracteres, pero también puede ser aplicable al reconocimiento de otros cuerpos periódicos en un sistema de pixeles.
Cómo estudiar, suspender y optimizar la propagación de infecciones epidémicas. El método dinámico de Monte Carlo
Authors: Burlak Gennadiy
Published: June 2023

Estudiamos una dinámica de la propagación de la infección epidemiológica a diferentes valores del factor de riesgo β (un parámetro de control) con el uso del enfoque dinámico de Monte Carlo (DMC). En nuestro modelo de juguete, la infección se transmite debido a los contactos de individuos que se mueven al azar. Mostramos que el comportamiento de los individuos recuperados depende críticamente del valor de β. Para valores subcríticos β <βc ~ 0,6, el número de casos infectados converge asintóticamente a cero, de modo que para un factor de riesgo moderado la infección puede desaparecer con el tiempo. Nuestras simulaciones mostraron que, con el tiempo, las propiedades de dicho sistema se acercan asintóticamente a la transición crítica en el sistema de percolación 2D. También analizamos un sistema extendido, que incluye dos parámetros adicionales: los límites de activación / desactivación del estado de cuarentena. Se encuentra que la cuarentena temprana da como resultado la dinámica oscilatoria irregular (con exponente de Lyapunov positivo) de la infección. Si el límite inferior de la cuarentena es lo suficientemente pequeño, la dinámica de recuperación adquiere una forma característica no monótona con varios picos amortiguados. También se estudia la dinámica de la propagación de la infección en el caso de los individuos con inmunidad.

Llamadas sin marcación: ayuda para discapacitados visuales y llamadas de emergencia
Authors: Hernández-Infante Joel , Gómez-Fuentes María del Carmen
Published: June 2023

Emergency calling shortcut es una aplicación para celular que tiene el propósito de ayudar a hacer llamadas telefónicas de emergencia a las personas con discapacidad visual o ciegas, sin embargo, ésta puede ser también útil a cualquier persona. Las llamadas se establecen más ágilmente que con el método convencional. Con esta aplicación no es necesario desbloquear el teléfono, ni solicitar su ejecución en el Smartphone, pues corre en segundo plano (así como WhatsApp). Con una combinación de movimientos simples del celular es posible llamar a tres números telefónicos diferentes, previamente guardados. La innovación principal es el uso del acelerómetro para interactuar con el usuario en combinación con el sensor de proximidad para evitar las llamadas no deseadas. Hasta donde sabemos, ésta aplicación es única en su forma de operar y más robusta que las que utilizan el botón de encendido/apagado ya que es prácticamente imposible que se establezcan llamadas de emergencia sin que el usuario lo solicite. Se sabe que las aplicaciones que usan el botón de encendido/apagado para establecer las llamadas algunas veces realizan llamadas no deseadas.

Authors: Santana Esparza Gil , Barrera Silva Gwendolyne
Published: June 2023

Los grandes avances en tecnologías proponen un nuevo reto a las instituciones de educación superior para proporcionar alternativas a los docentes que requieren cada vez más recursos para administrar los contenidos para las tutorías académicas. El propósito de este artículo es presentar las oportunidades que tienen las novedades tecnológicas en el proceso educativo, presentando una nueva herramienta para mejorar la calidad de la educación. Ya que cada docente tutor debe tener la capacidad de adaptarse a las nuevas exigencias y sobretodo utilizarlas para su conveniencia en el área de tutorías. En el mismo sentido, se puede afirmar que la tutoría es primordial para el desarrollo personal y académico del alumno ya que le proporciona un tutor que funge como un acompañante durante este proceso, lo cual permite estar cerca de la situación personalizada de aquel alumno que lo requiera. El tutor debe tener la misma perspectiva tanto en temas para lograr la confianza del alumno y de esa manera mantener su guía y acompañamiento, así como también debe tener un seguimiento permanente y pleno del desarrollo de su aspecto educativo y emocional; por lo cual es importante estandarizar la temática de tutorías para mejorar la atención a los alumnos.De ahí que el presente artículo presenta la propuesta de una plataforma en la modalidad Asistida por Computadora a partir del diseño y elaboración de los recursos digitales de la tutoría grupal con el fin de fortalecer el proceso.

Atenção à saúde bucal de pacientes com coagulopatias hereditárias
Authors: Ballardin Bárbara Soldatelli , Leidens Natali , Torres-Pereira Cassius Carvalho
Published: June 2023

Por apresentarem maior risco de sangramento durante a realização de procedimentos odontológicos, pacientes diagnosticados com coagulopatias ou trombopatias hereditárias apresentam, frequentemente, dificuldade de acesso à assistência odontológica na Atenção Primária em Saúde. Alguns centros especializados no tratamento dessas doenças contam com o cirurgião-dentista como parte da equipe multiprofissional, permitindo que a maioria dos pacientes realizem o acompanhamento odontológico em tais serviços.  Este estudo tem como objetivo relatar a experiência dos discentes de graduação e pós-graduação em Odontologia da Universidade Federal do Paraná na reabertura do ambulatório odontológico de assistência à pacientes com coagulopatias e trombopatias hereditárias do estado. Com a aposentadoria da profissional responsável pelos atendimentos odontológicos deste serviço, os pacientes ficaram desassistidos. Para suprir a demanda reprimida, o ambulatório foi reaberto como atividade extramuros da graduação e pós-graduação em Odontologia. Este fato possibilitou, além da retomada ao cuidado odontológico de pacientes com predisposição a hemorragias, o aprimoramento dos alunos no atendimento de pacientes com comprometimento sistêmico. A reabertura de um ambulatório de alta complexidade em saúde como campo de prática acadêmico é atípico, uma vez que comumente o processo se dá de forma inversa: o discente ingressando em um serviço bem estabelecido. Na presente experiência, os discentes tiveram atuação fundamental no restabelecimento da assistência à saúde pelo ambulatório de Odontologia do hemocentro.
Building School Data Equity, Infrastructure, and Capacity Through FAIR Data Standards: Findable, Accessible, Interoperable, and Reusable
Authors: Bowers Alex J. , Choi Yeonsoo
Published: June 2023

Despite increasing calls to build equitable data infrastructures, the education field has yet to have a shared guideline around equitable education data management and stewardship. To address this gap, we propose one framework from the data governance literature: the FAIR (Findable, Accessible, Interoperable, Reusable) data management principles complemented by the CARE (Collective benefits, Authority to control, Responsibility, Ethics) principles. We argue that making education data Findable, Accessible, Interoperable, and Reusable (FAIR) is a matter of equity and central to equity-focused data reuse. We illustrate the importance of FAIR education data by synthesizing our research experience and literature at the intersection of data governance and equity-focused data use.
Numerical Simulation of flow in pipe with cross jet effects
Authors: Hamad Karema Assi
Published: June 2023

A numerical method is developed to obtain two-dimensional velocity and pressure distribution through a cylindrical pipe with cross jet flows. The method is based on solving partial differential equations for the conservation of mass and momentum by finite difference method to convert them into algebraic equations. This well-known problem is used to introduce the basic concepts of CFD including: the finite- difference mesh, the discrete nature of the numerical solution, and the dependence of the result on the mesh refinement. Staggered grid implementation of the numerical model is used. The set of algebraic equations is solved simultaneously by “SIMPLE” algorithm to obtain velocity and pressure distribution within a pipe. In order to verify the validity for present code, the flow behavior predicted by this code is compared with these of another studies and there is a good agreement is obtained

Optimum allocation of water for restoration of Iraqi marshes is essential for different related authorities. Abo-Ziriq marsh area about 120 km2 is situated 40 km east of Al-Nassryia city. After comparing the measured annual water qualities with the Iraqi standards for surface water quality evaluation, Abo-Ziriq marsh water quality was in acceptable limit. Hydro balance computation were done for each month by using interface among the HEC-RAS, HEC-GeoRAS and ArcView GIS software and built a number of eco-hydro relationships to simulate the marsh ecosystem by using HEC-EFM program to estimate water allocation adequate for ecosystem requirement and constructs a GIS hydraulic reference map to show inundation area, depth grid and velocity distribution, the optimal flow result consists of three different scenarios (24, 30.3 and 33.6 m3 /s) for marsh operation during the year. A computer program in MATLAB 7 was developed to simulate the optimization model to determine the optimum flow value entry to lower zone. The priority of each parameter is represented by a weight associated with each of them (penalty factor). The model was used for different scheme of penalty factor value and examines three cases of flow (wet, moderate and dry years). The results obtained from the program run show that the optimum flow values are not affected significantly with changing the scheme of the penalty factors.Hence, any set of solutions can be use for operation the control structure of two inlets in the lower zone that best fits the objective of the system and increase flow release from Abo Jiry inlet to minimum deviation in water quality during the most time of the year

Published: June 2023

The study is devoted to both static and earthquake response analysis of retaining structures acted upon by lateral earth pressure. Two main approaches were implemented in the analysis, namely, the Mononobe-Okabe analytical method and the numerical Finite element procedure as provided in the ready software ABAQUS with explicit dynamic method. A basic case study considered in the present work is the bridge approach retaining walls as a part of AL-Jadiriya bridge intersection to obtain the effects of the backfill and the ground water on the retaining wall response including displacement of the retaining structure in addition to the behavior of the fill material. Parametric studies were carried out to evaluate the effects of several factors such as vertical and horizontal components of the earthquake, maximum peak acceleration, angle of friction, damping ratio, height of the wall and groundwater level within the medium of fill. Three heights of retaining walls were considered for those above mentioned factors, these are (2.9m, 4.7m and6.7m). A comparison is made between the responses obtained on the basis of finite element analysis with those obtained using the Mononobe-Okabe method. It is found that the lateral wall responses obtained using the FE were larger than those calculated by the Mononobe-Okabe method for all heights of the retaining wall, it was also found that pore pressure of the ground water depends on the water flow through the backfill during the earthquake. The distribution of the dynamic earth pressure on the wall is nonlinear and depends on the earthquake ground acceleration in addition to the wall height and soil properties. Based on the numerical analysis and the results obtained from the parametric studies carried out, two expressions are proposed to evaluate the maximum lateral wall response in terms of wall height, soil properties and earthquake base excitation acceleration, and hence the dynamic earth pressure acting on the retaining structure.

Roller Compacted Concrete (RCC) is a technology characterized mainly by the use of rollers for compaction; this technology achieves significant time and cost savings in the construction of dams and roads. The primary scope of this research is to study the durability and performance of roller compacted concrete that was constructed in the laboratory using roller compactor manufactured in local market. A total of (60) slab specimen of (38×38×10) cm was constructed using the roller device, cured for 28 days, then 180 sawed cubes and 180 beams are obtained from RCC slab. Then, the specimens are subjected to 60 cycles of freezing and thawing, sulfate attack test and wetting and drying. The degree of effect of the type of coarse aggregate (crushed and rounded), cement type (OPC and SRPC) and cement content on the durability of RCC were investigated. The results indicated that RCC that contain SRPC has beneficial effects on properties of RCC as compared to RCC that contain OPC after durability testing. Based on the testing results, it was concluded that the resistance of RCC specimens to freezing and thawing, wetting and drying and sulfate attack test increase as cement content increase. The results also indicate that using RCC that contain crushed aggregate has a positive effect on the overall properties of RCC, as compared with RCC that contain rounded aggregate after durability testing.

Published: June 2023

Aim: The study aimed to examine the relationship between individuals' distrust of the health care system and their health literacy levels and how demographic characteristics affect their level of distrust.

Materials and Methods: The research was conducted with 450 people over 18 living in the Selcuklu, Meram, and Karatay districts of the central districts of Konya province. A 32-question survey consisting of demographic questions, the Health Literacy Scale (HLS), and the Health Care System Distrust Scale (HCSD) was applied to the participants.

Results: According to the Pearson's correlation test conducted in the research, a negatively weak significant relationship was found between health literacy and distrust of health care systems, which associated increased health literacy with lower distrust. According to the regression analysis, there was a statistically significant relationship between health literacy and distrust of health care systems. Accordingly, 4.4% of the variance in distrust of health care systems was explained by health literacy (R2=0,044).

Result: The educational and income status positively affect individuals' level of health literacy. As health literacy level increases, trust in health care systems also increases. For trust to be established between health service providers and consumers, actions should be taken to improve their level of health literacy.

Purpose: Recently published studies indicate increased interest in remote health services that have expanded greatly with digitalization and whether they can be implemented into neuropsychological testing. Remote neurocognitive testing has become a frequently used approach today. The current study examines the concordance between the face-to-face and remote Oktem Verbal Memory Processes Test results of healthy young participants.

Method: 45 healthy young participants with a mean age of 23.41 were invited to participate in the study. Participants were 42.2% of male and 57.8% female. The Öktem Verbal Memory Processes Test was administered to participants. There was at least one week between face-to-face and remote testing. The results were compared with paired t-tests and Lin's Concordance Correlation analysis. Reliability was analyzed by examining the Intraclass Correlation Coefficient.

Results: For immediate memory score, ICC was 0.286 (95% CI: 0.016-0.524).. ICC of total learning score was calculated as 0.665 (95% CI: 0.465 -0.801). The highest learning score had an ICC of 0.868 (95% CI: 0.773 -0.926). ICC of the total inconsistency score was 0.639 (95% CI: 0.414 -0.79). Finally, the score for reaching the criterion displayed an ICC of 0.253 (95% CI: 0.079 -0.535).

Conclusions: The findings demonstrate that there is poor concordance between the results obtained with remote and face-to-face application of the Öktem Verbal Memory Process Test. As a result, using it remotely is not recommended at this stage.

Gastric cancer (GC) is one of the main causes of death from cancer with a multifactorial origin and is characterized by the expression of a gene known as HER2. This gene promotes cell proliferation and prevents apoptosis of cancer cells, facilitating uncontrolled cell growth. Trastuzumab Deruxtecan (T-DXd) is a drug for the treatment of tumors with a heterogeneous expression of HER2 that are resistant to conventional anti-HER2 therapy. It is believed that the positive results obtained from Trastuzumab Deruxtecan in the treatment ofgastric cancer are related to its potent inhibitory effect of topoisomerase I, the stability of the linker in plasma, as well as its bystander effect. Furthermore, the drug is more efficiently delivered to its target (tumor cell), resulting in a higher concentration of the cytotoxic agent at the site of action. Another point to highlight is that trastuzumab deruxtecan has benefits in treating breast cancer compared to other anti-HER2 therapies since more patients using this drug presented positive responses compared to trastuzumab emtansine (TDM1), in addition to presenting longer survival and fewer adverse effects. Thus, this literature review shows that T-DXd is a promising therapy of extreme importance and with great capability to respond to cancers with low expression of HER2 and to HER2-positive cancers that are insensitive to the trastuzumab emtansine drug.
