Computational radiative transport in complex geometries using orthogonal coordinates
Authors: Haque Md Ershadul , Mansoor Saad Bin , Yilbas Bekir Sami
Published: September 2023

Radiative heat transport involving complex geometries is an important area of investigation. The formulation of the transport phenomenon is more involved and consideration of the proper treatment of the irregular geometry becomes necessary for accurate estimation of heat transfer rates. Therefore, the present study focuses on the modeling and the solution of the radiative transfer equation (RTE) in an absorbing, emitting, and isotropically scattering, participating media for complex geometries using the body-fitted coordinates. The RTE in an orthogonal coordinate system is formulated and is then numerically solved in conjunction with a numerically generated, body-fitted, curvilinear coordinate system. The geometries are considered to be opaque and, in the analysis, both the radiative as well as the non-radiative equilibrium cases are considered. The formulation is validated through the previously published results. Notable agreement is observed between the results and those reported earlier for different complex geometries and various properties of the participating media.

The association between plasma concentration of pigment epithelium-derived factor and diabetic retinopathy
Authors: Şahin Tayfun , Karabulut Alpaslan
Published: September 2023

Objectives

Diabetic retinopathy (DRP) is one of the most common microvascular complications of diabetes. The pigment epithelium-derived factor (PEDF) is a protein that is one of the most potent angiogenesis inhibitors. The effect of blood PEDF concentration on DRP formation remains unclear. The present study aimed to determine whether the plasma concentration of PEDF is effective on the appearance of DRP.

Methods

The present study consisted of 62 patients with diabetes mellitus and 20 healthy participants. The patient group included 28 patients with non-proliferative DRP, 13 with proliferative DRP, and 21 diabetic patients without DRP. The PEDF levels in patient serum samples were detected through the ELISA method. The body mass index of the participants was calculated.

Results

Serum PEDF levels of diabetic patients (1.533 ± 0.233 μg/mL) were found to be lower (2.163 ± 0.343 μg/mL) than healthy participants (p=0.002). The PEDF levels were similar in the DRP and non-DRP groups (p=0.337). The plasma PEDF level decreased along with the progression of DRP (p=0.001).

Conclusions

The PEDF concentration in the blood decreases along with the increase of DRP grade. Decreased blood concentration of PEDF may be important to predict microvascular complications. Agents containing PEDF may be used intraocularly/systemically for therapeutic purposes to prevent vascular complications of diabetes in the near future.
Amphetamines Improve the Motivation to Invest Effort in Attention-Deficit/Hyperactivity Disorder
Authors: Chong Trevor T.-J. , Fortunato Erika , Bellgrove Mark A.
Published: September 2023

Prevailing frameworks propose that a key feature of attention-deficit/hyperactivity disorder (ADHD) is lower motivation. An important component of motivation is the willingness to engage in cognitively or physically effortful behavior. However, the degree to which effort sensitivity is impaired in ADHD has rarely been tested, and the efficacy of stimulant medication in ameliorating any such impairments is unclear. Here, we tested 20 individuals with ADHD (11 males, 9 females) who were managed with amphetamine-based medication (dexamfetamine, lisdexamfetamine), and 24 controls (8 males, 16 females). Individuals with ADHD were tested over two counterbalanced sessions, ON and OFF their usual amphetamine-based medication. In each session, participants performed an effort-based decision-making task, in which they were required to choose how much cognitive or physical effort they were willing to engage in return for reward. Our results revealed three main findings. First, individuals with ADHD had lower motivation relative to controls to invest effort in both the cognitive and physical domains. Second, amphetamine increased motivation uniformly across both domains. Finally, the net effect of amphetamine treatment was to mostly restore motivation across both domains of effort relative to healthy controls. These data provide clear evidence for a heightened sensitivity to both cognitive and physical effort in ADHD, and reveal the efficacy of amphetamine-based drugs in restoring effort sensitivity to levels similar to controls. These findings confirm the existence of reduced motivational drive in ADHD, and more broadly provide direct causal evidence for a domain-general role of catecholamines in motivating effortful behavior.

SIGNIFICANCE STATEMENTA core feature of attention-deficit/hyperactivity disorder (ADHD) is thought to be a heightened aversion to effort. Surprisingly, however, the degree to which effort sensitivity is impaired in ADHD has rarely been tested. More broadly, the relative efficacy of catecholamines in motivating the investment of cognitive and physical effort is unclear. We tested 20 individuals with ADHD ON and OFF amphetamines, and compared their behavior on an effort-based decision-making task to 24 controls. When tested OFF medication, the ADHD group was less cognitively and physically motivated than controls. However, amphetamines led to a comparable increase in motivation across both domains. This demonstrates the efficacy of catecholamines in facilitating domain-general effort, and highlights the broader potential of such drugs to treat disorders of motivation.

Mitochondrial DNA (mtDNA) leakage into the cytoplasm can occur when cells are exposed to noxious stimuli. Specific sensors recognize cytoplasmic mtDNA to promote cytokine production. Cytoplasmic mtDNA can also be secreted extracellularly, leading to sterile inflammation. However, the mode of secretion of mtDNA out of cells upon noxious stimuli and its relevance to human disease remain unclear. Here, we show that pyroptotic cells secrete mtDNA encapsulated within exosomes. Activation of caspase‐1 leads to mtDNA leakage from the mitochondria into the cytoplasm via gasdermin‐D. Caspase‐1 also induces intraluminal membrane vesicle formation, allowing for cellular mtDNA to be taken up and secreted as exosomes. Encapsulation of mtDNA within exosomes promotes a strong inflammatory response that is ameliorated upon exosome biosynthesis inhibition in vivo. We further show that monocytes derived from patients with Behçet's syndrome (BS), a chronic systemic inflammatory disorder, show enhanced caspase‐1 activation, leading to exosome‐mediated mtDNA secretion and similar inflammation pathology as seen in BS patients. Collectively, our findings support that mtDNA‐containing exosomes promote inflammation, providing new insights into the propagation and exacerbation of inflammation in human inflammatory diseases.

Authors: Wei-Ying Li , Tzu-Chuen Lu
Published: September 2023

This study investigates the effect of programming courses on the computational thinking (CT) skills of elementary school students and the learning effectiveness of students from different backgrounds who are studying programming. We designed a OwlSpace programming course into an elementary school curriculum. Students in fourth and fifth grades were taught the fundamentals of programming. We measured and analyzed the effectiveness of their CT skills and self-efficacy in CT. The researchers analyzed the changes in the CT of different gender, different grade, and different past experience students in programming courses and then made specific recommendations for information technigy teachers and related units. The results demonstrate that students learned and improved their CT skills by taking OwlSpace programming course. Additionally, gender, grade, and past experience are found to have no impact on the students’ learning that means the course can improve students ability without limited any characteristics.

Purpose: justification, application of stretching in the process of physical rehabilitation. Materials and methods: We used such a research method as the analysis of literary sources on the research topic. Results: According to literature sources, stretching exercises improve blood circulation in the muscles, which, in turn, helps to "recharge" them by increasing the removal of lactic acid from them. Such exercises also contribute to an increase in oxygen consumption and intensification of metabolism. In the process of physical rehabilitation, stretching exercises are performed after a classical therapeutic massage. The number of repetitions of each exercise is 3-4 times, with a pose delay of at least 5 seconds. Conclusions: Therefore, the use of a complex of physical exercises based on the stretching method helps to avoid the deterioration of blood circulation in the muscles, to create a strong muscle corset, to increase the elasticity of the pectoral muscles and is an effective preventive measure against muscle injuries.

This proceeding presents a new approach to determining energy indicators, such as specific fuel consumption and the energy efficiency ratio of a power generating plant. The essence of the new method is to determine the instantaneous power of the installation followed by data processing through integration. The use of this method made it possible to establish the dependence of specific energy indicators on the load level of the generating plant. The established distri-bution allows you to determine the optimal parameters of the experimental installation and consumption at different load levels. The highest specific fuel energy consumption is observed (1189–1297 g/(kW×h) and 962–1147 g/(kW×h)) at the lowest and heaviest load with different types of fuel. Experimental data confirmed that fuel without ethanol impu-rities allows generating a larger amount of electrical energy, which is advisable to use when greater needs arise. Bibl 8, fig. 2, tables 3.

The article analyzes the methods of estimating the parameters and regimes of electrical distribution networks in areas of low-rise urban development. A method for optimizing the parameters of distribution networks of 0.38 kV under conditions of uncertainty of the initial information is proposed. It is shown that one of the unsolved problems of calculating the parameters of distribution electric networks of cities is the determination of the estimated load of utility consumers. Its dependence on the characteristics of consumers and their number connected to the lines of city transformer substations causes the low accuracy of calculations. In this case, the error of calculating the transformer substations load can reach 10-25%, and the error of calculating the cross-sections of 0.38 kV lines reaches 40%. In the assumption of the constancy of the total length of the lines of urban electric networks and the invariance of the distance between loads, calculation formulas for linear moments and load distribution coefficients are proposed, and based on them, models of intersection and power losses in lines are developed. Taking into account the developed models, we offer discounted cost models for 0.38 kV networks and transformer substations when calculating economic current density and allowable voltage costs. Keywords: optimization, distribution networks, uncertainty, efficiency, low-rise building, scheme.

Aim of the study: Intraneural ganglion cysts are a relatively uncommon type of ganglion cyst that can affect peripheral nerves. They are particularly rare in the upper limb, and even more so in the median nerve, with the vast majority of them occurring in the peroneal nerves. This paper aims to make the reader aware of this relatively uncommon condition. Case description: We report a case of a 41-year-old male who presented with a gradually progressing mass on the volar aspect of the wrist extending to the index finger. The nonspecific presentation as well as the rarity of the condition may make diagnosis challenging. The patient was referred for surgical management under a specialist peripheral nerve hand surgeon. Conclusions: Ultrasound and magnetic resonance imaging as well as awareness of the typical imaging features of this entity are crucial in making the correct diagnosis as well as excluding other potential considerations such as neoplasm.

Thermobifida alba is the mesophilic member of the Thermobifida genus, the genome and enzyme sets of which have not been described and published yet. Thermobifida strains are thermotolerant actinomycete, which possess wide sets of cellulose and hemicellulose hydrolysing enzymes. Previously, three endomannanases (Man5ATh, Man5ATc, and Man5AThf) of thermobifidas were cloned and investigated, and hereby the endomannanase of T. alba DSM 43795 is described. All four endomannanases belong to the glycoside hydrolase family 5, their sizes are around 50–55 kDa. Their structure consists of a catalytic domain and a carbohydrate binding module, while there is an interdomain linker region in-between consisting repetitive tetrapeptide motifs (eg.: PPTEPTD-Ta, PTDP-Tc, TEEP-Tf, DPGT-Th). The pH optima of Man5A enzymes from T. alba, Thermobifida halotolerans, Thermobifida cellulosilytica, and Thermobifida fusca are slightly different (6.5, 7.0, 7.5, and 8.0, respectively), however, the temperature optima of the enzymes were detected within a wider range of 65–75 °C. In this research, Man5ATa exhibited the lowest Michaelis-Menten constant (KM) (0.13 mM) on LBG-mannan substrate, while others shared similar kinetic parameters: 0.9–1.7 mM of KM. Despite the high sequence similarity of the investigated mannanases, they exhibit different temperature stability parameters. These different functional characteristics can be advantageous for industrial applications producing biologically active, oligomannan prebiotics under different conditions.
New technologies in the court: Remote hearings and hybrid interpreting during the pandemic
Authors: Lea Láncos Petra
Published: September 2023

Fair trial is the cornerstone of all judicial proceedings and a fundamental right guaranteeing, among other things, the right to interpreting to those who do not understand and speak the language of the court. With the outbreak of the COVID pandemic, courts around the world struggled to continue adjudication, turning to the solution of remote hearings and hybrid interpreting to comply with requirements of both health policy and the right to linguistic presence in judicial proceedings. This paper describes the solutions applied in domestic, international and EU courts, shedding light on the shortcomings of remote hearings and their possible detrimental effects on interpreting and fair trial.
Testing the working memory capacity of dialogue interpreters
Authors: Tiselius Elisabet , Englund Dimitrova Birgitta
Published: September 2023

Allocation and management of working memory resources are crucial for successful interpreting. A number of studies have found clear indications that simultaneous interpreters have larger working memory capacity, at least in some areas, than other bilinguals. To date, no studies have focused on the working memory of dialogue interpreters. The study reported in this paper investigated the main differences and similarities in working memory between experienced and inexperienced dialogue interpreters when it comes to central executive functions. We also compared experienced dialogue interpreters to experienced simultaneous conference interpreters. Fifteen dialogue interpreters with two working languages, Swedish and either French, Polish or Spanish, participated in the following working memory tests: tests for updating (2-back), inhibition (arrow flanker), attention-sharing, storage and processing (Barrouillet, letter span, matrix span, operation span). We found no significant differences between the experienced and inexperienced dialogue interpreters, and there were significant differences between the experienced dialogue interpreters and a comparison group of experienced simultaneous conference interpreters (n = 28). Although the number of participants is small, the study may serve as a baseline for future work on the cognition of dialogue interpreting.
What hinders the training of specialists in the construction and operation of road bridges in modern conditions
Authors: Ovchinnikov Igor , Valiev Sherali , Ovchinnikov Ilya
Published: September 2023

The issue of training bridge engineers in universities in the Russian Federation is being addressed. It has been noted that there has been a decline in the education of bridge building in Russian universities, particularly in the northwestern, southern, and Trans-Baikal regions bordering the Pacific Ocean. Attention is drawn to the fact that the proposed draft concept for road education development until 2035 has not yet been approved by the Ministry of Science and Higher Education of the Russian Federation, which leads to questions about how universities with different affiliations will interact and a lack of supporting legal documents. The draft also lacks information about undergraduate and graduate programs. The quality of the staff in the graduation departments of universities is also low, with the salaries of teaching staff nearly two times lower than the median salary of road workers. Acquiring the titles of associate professor and professor requires a significant amount of time and effort. The number of teaching staff is determined based on the number of students, not the workload, which leads to universities retaining weaker students. Graduate school scholarships are also very low, and most graduate students work, which results in delays in defending dissertations and an unwillingness to stay in the department. The high workload and lack of incentives also discourage writing books and manuals, especially given the current advancements in bridge building. For regional universities to be effectively operated and developed, three conditions must be met: availability of funding, competent leadership, and talented personnel, which are currently lacking. This is why scientific research is not being conducted in universities, especially since Rosavtodor cannot fund fundamental or exploratory research. The article concludes by discussing the experience of training highly qualified specialists at Tyumen Industrial University in collaboration with Mostostroy-11 Joint-Stock Company. The organization of the educational process and the approximate topics of final qualification works are described. All undergraduates conduct patent searches and use patents in developing their master’s theses. The results of their research are published in journals listed by the Higher Attestation Commission.

Dominância fiscal e dominância monetária para o Brasil: uma análise empírica a partir de projeções locais no período de 1999 a 2022
Authors: Flora Mariana Silva , Santolin Roberto
Published: September 2023

Resumo Este artigo avalia sob quais condições a economia brasileira esteve sob dominância fiscal ou monetária no período de janeiro de 1999, início do Regime de Metas de Inflação, até novembro de 2022. A definição de dominância fiscal utilizada foi a de Blanchard (2004), pela qual o Brasil está sob dominância fiscal quando a política monetária não é capaz de controlar a taxa de câmbio. Os resultados alcançados neste artigo, por meio de análises impulso resposta baseado em Projeções Locais, permitem concluir que no período de alto endividamento houve dominância monetária. Tal resultado é condizente com ampliação do superávit fiscal associado à elevação dos juros e à valorização do câmbio real. Porém quando a dívida líquida interna esteve relativamente baixa observou-se dominância fiscal e a ausência de resposta do superávit fiscal ao crescimento dos juros não permitiu que a política monetária afetasse a trajetória do câmbio.

ABSTRACT: Fertigation is widely used in seedling production for different crops, including passion fruit. There is no consensus on the ideal nutrient solution, and as such, nurseries have used fertigation empirically. This study assessed the electrical conductivity of nutrient solution containing macro and micronutrients in passion fruit seedling production and compared it with commercially used fertigation. A completely randomized design was used, with five treatments and six repetitions. Four electrical conductivities (0.5, 1.0, 2.0 and 4.0 dS m-1) of a complete nutrient solution and an additional treatment (commercial nutrient solution) were analyzed. Daily fertigation with a complete nutrient solution (macro and micronutrients) at electrical conductivities between 2.6 and 3.3 dS m-1 followed by two daily irrigations are efficient at producing FB 300 “Araguari” passion fruit seedlings in coconut fiber substrate, with benefits such as greater biomass and better Dickson quality index when compared to commercial nutrient solution.

ABSTRACT: Hemoptysis associated with respiratory disorders are some findings of caudal vena cava thrombosis (CVCT) in cattle. Nevertheless, CVCT may be accompanied by a broad spectrum of clinical signs and gross lesions. This study reported the frequency of CVCT in cattle necropsied in Southern Brazil and described its clinical signs, as well as pathological findings. From a total of 1,976 postmortem examination reports in cattle in Southern Brazil, there were 30 cases (1.5%) of CVCT. In the clinical evaluation, the main clinical course was chronic (13/30), followed by peracute (7/30), acute (4/30), and subacute (5/30). Hemoptysis (17/30), dyspnea (8/30), and anorexia or hyporexia (7/30) were the most reported clinical signs. Septic thrombophlebitis of the caudal vena cava (24/30), hepatic abscesses (24/30), pulmonary hemorrhage (23/30), and embolic pneumonia (19/30) were the main lesions observed at the necropsy. We concluded that CVCT is a relevant cause of death in bovines from Santa Catarina state, mainly in adult dairy cows. The disease is characterized by a wide range of clinical signs and lesions, requiring attention from veterinarians for the correct diagnosis. Furthermore, the association between the clinical history, clinical signs, and lesions is essential for the diagnosis of CVCT in cattle.

Resumo Os tumores do Sistema Nervoso Central (SNC) representam mais da metade das neoplasias infantis malignas que acometem crianças. Objetivou-se analisar o risco de exposição a agrotóxicos relacionado com o desenvolvimento de tumores do SNC em crianças. Realizou-se uma revisão sistemática da literatura nas bases de dados PubMed/MEDILINE, Embase, Web of Science, Scopus e CINAHL. Foram incluídos estudos de coorte e caso-controle sobre o desenvolvimento de tumores do SNC (todos os tipos histológicos do grupo III Classificação de Câncer Infantil) decorrentes da exposição a agrotóxicos em crianças de 0-14 anos. Na metanálise utilizou-se o modelo de efeito aleatório e o método estatístico de Mantel-Haenszel. A Razão de Chances (RC) ou Odds Ratio (OR) foi a medida de associação aplicada. A revisão foi registrada no International Prospective Register of Systematic Reviews (PROSPERO) sob o número CRD42021209354. A busca identificou 1.158 estudos, dos quais 14 compuseram a revisão. Verificou-se evidência de associação entre o desenvolvimento de astrocitomas e a exposição a todas as classes de pesticidas (OR 1,50; IC95% 1,15-1,96; p=0,03). A síntese dos resultados apontou para uma relação da exposição aos agrotóxicos com o desfecho de alguns tipos histológicos de tumores do SNC na infância.
A experiência de adoecimento falciforme pelas lentes qualitativas
Authors: Lopes Winnie Samanú Lima , Moreira Martha Cristina Nunes , Gomes Romeu
Published: September 2023

Resumo O objetivo deste artigo é analisar o conteúdo da produção qualitativa produzida (2000-2023) sobre a doença falciforme, a fim de fundamentar a categoria analítica - experiência de adoecimento falciforme. Metodologicamente, realizamos um estudo bibliográfico de abordagem qualitativa, com uma análise de conteúdo temática, ancorada no diálogo entre o acervo revisado e os referenciais teórico-conceituais adotados. A análise de conteúdo temática nos levou a oito dimensões interpretativas: cotidianos e itinerários, cuidado, decisões reprodutivas, estigma e suas expressões, gênero, participação, raça e religiosidade. A experiência falciforme emerge relacionada a processos de exclusão, desvalorização, desconhecimento e invisibilização, aliadas fortemente aos componentes de raça em nuances que a distanciam da experiência de adoecimento genérica.
Beyond Institutional Racism? An analysis of the content of the Black Population Health Policy

Published: September 2023

Abstract The concept of Institutional Racism (IR) gained emphasis in the late 1990s and the 2000s. It became one of the central terms in the discussion on racism and the Black Population Health. In Brazil, this category hegemonically influences the understanding of racism in health studies and debates. This qualitative case study paper analyzes the incorporation of the IR concept in Brazil in implementing the National Comprehensive Health Policy for the Black Population. Government documents from the Ministry of Health and the Institute of Applied Economic Research were analyzed. Although the formal inclusion of the discussion about IR in the public policy agenda in the early 21st century is a great achievement, apprehending this fact in isolation disregards the dialectical interaction between individual, institutional, and structural forms in the racialization dehumanizing process. Thus, combating IR depends on facing the reasons that lead institutions to reproduce racism and its consequences on access to housing, work, education, and health services and actions.
Cuidado em Saúde e mulheres negras: notas sobre colonialidade, re-existência e conquistas
Authors: Barbosa Ana Cláudia , Oliveira Roberta Gondim de , Corrêa Roseane Maria
Published: September 2023

Resumo Refletimos sobre a saúde da mulher negra como parte integrante do enredo produzido pelo exercício do poder na colonialidade, e as forças que atuam no sentido da definição e imposição do lugar de subalterna, pois que informada pela noção objetificada e racializada de corpo. Mulheres negras estão substancialmente representadas nos piores indicadores de saúde. Propomos olhar o campo da saúde coletiva, em especial problematizando a dimensão do cuidado, enquanto tecnologia política, social e intersubjetiva, cujos encontros com o corpo estético-político da mulher negra são atravessados por experiências singulares de exclusão. Mas, para além do sofrimento, falamos também de agência e resistência, bem como da construção de uma agenda de luta a partir do protagonismo de negras/os.
Health care and black women: notes on coloniality, re-existence, and gains
Authors: Barbosa Ana Cláudia , Oliveira Roberta Gondim de , Corrêa Roseane Maria
Published: September 2023

Abstract We reflect on Black women’s health as part of a narrative produced by the exercise of coloniality and the forces that contribute toward defining and imposing the place of a subaltern since the objectified and racialized body notion informs it. Black women are represented in the worst health indicators. We propose to look at collective health from the perspective of care as a political, social, and intersubjective technology, in whose encounters with the aesthetic-political body of Black women are traversed by unique exclusion experiences. Moving beyond suffering, we also address agency, resistance, and the construction of an agenda of struggle based on the Black people’s leading roles.

Abstract This study aims to identify the Popular Health Surveillance practices in Brazil, described in the scientific literature. A scoping review was carried out in the LILACS, MEDLINE, MEDCARIB, PAHO-IRIS, WHOLIS, and Scopus databases from the CAPES Periodical Portal in May 2022. Studies that clearly addressed community/population protagonism in a health surveillance experience were included in the review, with a total of 6 studies. Three categories resulted from the analysis: 1. Cues for Popular Surveillance in Health; 2. Fundamental principles of Popular Surveillance; and, 3. Pandemic and Popular Protagonism. The studies address experiences of Popular Surveillance with different actions of population groups for the production of health that experience the different risks and impacts of the productive processes in the environment, in health and in their ways of life. It highlights the importance of strengthening the Popular Surveillance representation based on the articulation of knowledge of the actors involved with data production, health promotion and health care in the territories.

Resumo Compreendendo que o racismo integra a realidade brasileira constituindo um determinante social do processo saúde-doença, este artigo procura refletir acerca dos efeitos do racismo na subjetividade e sobre o cuidado ofertado às mulheres negras. As reflexões derivam de uma pesquisa qualitativa, utilizando o método biográfico, em que mulheres negras narraram suas vidas e suas experiências com o racismo. As narrativas visibilizam os efeitos negativos das vivências sistemáticas do racismo estrutural nas imagens sobre si das mulheres ouvidas e a falta e/ou pouca efetivação das políticas públicas existentes de saúde integral para transformar o status quo.
“My life is about to take care of myself”: therapeutic itineraries of care for frail older adults

Published: September 2023

Abstract The present study sought to understand how frail older adults perceive their therapeutic care itineraries. This qualitative research was based on Critical Medical Anthropology. Data were collected through interviews in the homes of 22 older adults, whose average age was 79. The emic analysis was guided by the model of Signs, Meanings, and Actions. All interviewees expressed access to professional care in their trajectories, which are understood as insufficient, unprepared, prejudiced, uncomfortable, contradictory, (un)accessible, realization, respectful, and excessive. Therapeutic itineraries were also revealed in the psychosocial and cultural spheres. Several day-to-day actions were evaluated and interpreted in the record of self-care and justified by this end: the time they wake up, sleep, what they eat, and how they behave. They face the lack of care policies in their trajectories, labeling their bodies as undesirable due to physical, symbolic, communicational, attitudinal, systematic, cultural, and political barriers. Thus, they bring to light therapeutic pluralism, challenges, confrontations, insistence, and resistance in maintaining care when experiencing old age with frailties.
