Published: September 2024

Abstract Objective Executive dysfunction after traumatic brain injury may lead to reduced daily functionality due to direct damage to the frontal lobe or to disruption of its connections to other brain regions. This study aimed to compare the performance of adults with and without traumatic brain injury on executive functions tasks. Method The present study had a descriptive transversal design and included 43 participants divided into a clinical group (N = 23, age M = 34.3 [10.86]) and a control group (N = 20, age M = 38.3 [10.7]). The battery consisted of traditional instruments and the Ecological Hotel Task. Results A significant difference was found in the performance of the groups in the planning measures (number of tasks [t = -3.06; p < 0.01] and planning score [t = -3.06; p < 0.01]), highlighting the advantages of using both the traditional performance paradigms and the ecological tasks in neuropsychological assessment of executive functions. Conclusion Results suggested that the ecological task might discriminate better executive dysfunction, emphasizing the importance of using activities that simulate real-life situations of the participants.
O EFEITO DA IMAGINAÇÃO TÉCNICA NA LITERATURA
Authors: Maciel Ulysses
Published: September 2024

Resumo Objetos técnicos aparecem nas obras literárias como objetos situados no limite entre a arte e a técnica, entre a magia e a razão, entre o real e a representação. Nessa zona fronteiriça onde se desenvolve o discurso literário, o objeto técnico é o desencadeador da ambigüidade e da ilusão. Lima Barreto, no conto Um e outro, mira um automóvel mas acerta a hesitação de Lola, personagem dividida entre a imaginação do objeto e a paixão pelo chauffeur. Cortázar, no conto Las babas del diablo, e Antonioni, no filme Blow up, desconstroem a fotografia como imitação do real. As narrativas desses autores ultrapassam a mera utilidade dos objetos técnicos e apontam para um imaginário que liberta o ser humano de uma relação direta com a técnica. O que este trabalho busca é localizar esses textos literários na zona fronteiriça entre o simbólico e o técnico.
O DISCURSO DE NEUTRALIDADE NA IMPRENSA
Authors: Melo Sandra Helena Dias de
Published: September 2024

Resumo Este trabalho objetiva mostrar o modo como manuais de redação e estilo jornalísticos constroem a imagem neutra do texto noticioso e da imprensa. Considerando que a língua não é algo transparente e nem simplesmente um instrumento para a comunicação (FAIRCLOUGH, 2001), analisou-se o modo como a informação, o objeto primordial da imprensa, a partir de técnicas para a padronização da linguagem jornalística, tende a ser vista como se fosse um produto imparcial desse veículo de comunicação. Foram analisados, com esse propósito, os manuais dos jornais Folha de S. Paulo e O Estado de S. Paulo. O exame do material permitiu as seguintes conclusões: 1) a imprensa identifica o texto noticioso como completo e imparcial; 2) a língua da imprensa é sustentada como transparente e, conseqüentemente, 3) a imprensa ganha uma imagem neutra.

IDEOLOGIAS LINGUÍSTICAS ENTRE INVENÇÕES E AFETOS: UMA CONTRIBUIÇÃO FEMINISTA
Authors: Dias Ana Luiza Krüger
Published: September 2024

Resumo Este artigo é uma contribuição teórica de inspiração feminista ao campo das ideologias linguísticas provocada pelas disputas metadiscursivas em torno dos usos do gênero gramatical no Português Brasileiro. A partir da reflexão crítica sobre a conceituação do termo “ideologia linguística” na literatura, propõe-se a necessidade de inserção de duas dimensões geralmente relegadas neste debate: a inventiva e a afetiva. Para tanto, discute-se como as ideologias linguísticas operam com base em crenças sobre como a língua funciona ou deveria funcionar, mas são construídas enquanto representações ligadas a regimes ontológicos de verdade referencial. Pensar o funcionamento ideológico da linguagem a partir das perspectivas da invenção (Wagner, 2012) e do afeto (Ahmed, 2014) enquanto ferramentas teóricas e práticas de ação social preconizadas pelos estudos feministas possibilita entender em maior profundidade as pressuposições e acarretamentos de uma política de signos que alinha determinados corpos falantes entre si, excluindo outros da matriz normativa de significados, legitimando e sedimentando projetos de hierarquização e exclusão.

Authors: Cavalcanti Larissa de Pinho , Silva Rebeca Rocha Novaes
Published: September 2024

Resumo Analisam-se neste artigo três postagens sobre aleitamento materno na rede social Instagram, elaboradas por profissionais de saúde que atendem ao público materno-infantil entre 2019 e 2021 durante a Semana Mundial do Aleitamento Materno. Para tanto recorreu-se à análise multimodal de discursos (Jewitt, 2001; O’Halloran, 2009, 2011) com suporte da gramática do design visual (Kress; Van Leeuwen, 1996), bem como à compreensão discursiva de Van Dijk (1985, 2022) e à teoria da valoração (White, 2001, 2015). As evidências sugerem ser possível identificar nas postagens que os perfis de profissionais da saúde recorrem ao afeto e aos conhecimentos laicos para promover a prática do desmame, enquanto postagens que defendem o aleitamento usam a cientificidade e os dados demográficos em sua construção discursiva.
ARGUMENTUM AD ANTIQUINOVITATEM COMO ESTRATÉGIA DA PERSUASÃO NOSTÁLGICA NO DISCURSO PUBLICITÁRIO
Authors: Carvalho Richarles Souza de
Published: September 2024

Resumo O discurso publicitário é uma das principais manifestações de linguagem na atualidade. Meu principal objetivo com este artigo é demonstrar como a publicidade se vale de estratégias de persuasão na promoção de produtos e instituições, mobilizando a memória e a nostalgia. Metodologicamente, faço uma análise discursiva de vídeos publicitários institucionais do campo educacional e do campo automobilístico. Analiso três vídeos disponíveis na plataforma YouTube. A partir da análise, assevero que o discurso publicitário constrói, por meio de estratégias retóricas, um processo que chamo de persuasão nostálgica, mesclando palavras e imagens e conectando o novo em coexistência com o passado. A principal estratégia retórico-textual utilizada neste processo é o argumentum ad antiquinovitatem.

Published: September 2024

Abstract Introduction: The malnutrition-inflammation process is one of the main causes of morbidity and mortality in patients with chronic kidney disease (CKD), influencing quality of life. The aim of this study was to identify the inflammatory and nutritional status of elderly hemodialysis (HD) and its association with quality of life. Methods: This study was carried out in health services in three different cities. The Malnutrition-Inflammation Score (MIS) was used to assess the inflammatory and nutritional status, with anthropometric measurements, protein status, lean mass and function. The quality of life was assessed using KDQOL-SFTM. Data were analyzed using multivariate analysis and the Poisson model to evaluate the factors that increased the risk of developing malnutrition and inflammation. Results: The MIS identified a 52.2% prevalence of malnutrition and inflammation in the population. In univariate analysis, most KDQOL-SFTM domains presented higher scores for nourished elderly. Anthropometric measures associated with muscle mass and functionality were lower in the malnourished elderly. Multivariate modeling revealed a higher nutritional risk of 50.6% for women and older age, since with each additional year of life the risk of malnutrition increased by 2.4% and by 0.4% with each additional month on HD. Greater arm muscle circumference (AMC) and higher serum albumin were factors for reducing malnutrition by 4.6% and 34.7%, respectively. Conclusion: Higher serum albumin and preserved AMC have been shown to be good indicators of better nutritional status. Higher MIS was associated with poorer quality of life, older age, lower income and education, longer time on dialysis, and presence of comorbidities.

Resumo Introdução: O processo de desnutrição-inflamação é uma das principais causas de morbimortalidade em pacientes com DRC, influenciando a qualidade de vida. O objetivo deste estudo foi identificar o estado inflamatório e nutricional de idosos em hemodiálise (HD) e sua associação com qualidade de vida. Métodos: Estudo realizado em serviços de saúde de três cidades diferentes. O Escore de Desnutrição-Inflamação (MIS, por sua sigla em inglês) foi utilizado para avaliar estado inflamatório e nutricional, com medidas antropométricas, estado proteico, massa magra e funcionalidade. A qualidade de vida foi avaliada com KDQOL-SFTM. Os dados foram analisados utilizando análise multivariada e modelo de Poisson para avaliar fatores que aumentaram o risco de desenvolver desnutrição e inflamação. Resultados: O MIS identificou prevalência de 52,2% de desnutrição e inflamação na população. Na análise univariada, a maioria dos domínios do KDQOL-SFTM apresentou escores maiores para idosos nutridos. Medidas antropométricas associadas à massa muscular e funcionalidade foram menores em idosos desnutridos. A modelagem multivariada revelou maior risco nutricional de 50,6% para mulheres e idosos pois o risco de desnutrição aumentou em 2,4% para cada ano adicional de vida e em 0,4% para cada mês adicional de HD. Maior circunferência muscular do braço (CMB) e maior albumina sérica foram fatores de redução da desnutrição em 4,6% e 34,7%, respectivamente. Conclusão: Demonstrou-se que albumina sérica mais elevada e CMB preservada são bons indicadores de melhor estado nutricional. Maior MIS foi associado a pior qualidade de vida, idade mais avançada, menor renda e escolaridade, maior tempo em diálise e presença de comorbidades.

Abstract Piper aduncum L., a Brazilian medicinal plant, is known for its bioactive properties, including repellent and insecticidal effects. This study investigated the insecticidal potential of essential oils (EOs) from P. aduncum, collected during the dry and rainy seasons, against fleas (Ctenocephalides felis felis Bouché, 1835) in egg and adult stages. The EOs were obtained by hydrodistillation using a modified Clevenger apparatus for 2 h. Qualitative and quantitative analysis were performed via gas chromatography. The findings revealed that dillapiole was the predominant substance in both EOs, accounting for 77.6% (rainy) and 85.5% (dry) of the EOs. These EOs exhibited high efficacy against the parasite C. felis felis, resulting in 100% egg mortality at a concentration of 100 μg/mL and 100% mortality for adult fleas starting from 1,000 μg/mL. Dillapiole standard was also effective but at a relatively high concentration. This finding suggested that EOs from P. aduncum exhibit cytotoxicity against these pests and might hold potential for commercial production, offering practical applications for such bioprospecting. This study uniquely revealed that the EOs from P. aduncum, which is rich in dillapiole, demonstrated pulicidal activity against the parasite C. felis felis, particularly in inhibiting the hatching of the eggs of these parasites.

Published: September 2024

Abstract An evaluation was made of the larvicidal efficacy of lotilaner (Credeli®) in the treatment of dogs naturally infested with Dermatobia hominis larvae. A total of 12 dogs presenting at least three live D. hominis larvae were medicated. The animals were medicated orally with a single dose of no less than 20 mg/kg lotilaner. After drug administration, the animals remained at their homes, and observations were made to verify the larvicidal effect 6 hours after treatment. Live larvae were considered any parasite that exhibited motility after removal. For each animal was using the formula: 100 x [(total of live larvae before treatment − total live larvae after treatment) /total of live larvae before treatment] as criteria for evaluating lotilaner efficacy. A total of 98 larvae were counted in 12 dogs, with an average of 8.1 larvae per animal. The effectiveness of lotilaner was 80.6%. Nineteen larvae were found alive, albeit presenting hypomobility and lethargic behavior. However, note that the evaluation was performed just six hours after administration of the drug. Lotilaner administered orally in a single dose of 20 mg/kg showed 80.6% efficacy six hours after treating dogs naturally infested with D. hominis.
CO2 uptake of cement by-pass dust via direct aqueous carbonation: an experimental design for time and temperature optimisation
Authors: Bonfante Francesca , Humbert Pedro , Tulliani Jean-Marc , Palmero Paola , Ferrara Giuseppe
Published: September 2024

The compositional characteristics of cement by-pass dust (CBPD), specifically its alkalinity and salt content, present significant limitations to its reinsertion in cement production. Furthermore, these characteristics give rise to considerable concerns regarding its disposal. The present study investigated the potential for treating CBPD through the application of a direct aqueous carbonation technique. The aim is to assess carbon capture potential of the material and to investigate the impact of the mineralisation process on its composition. The process was conducted under atmospheric pressure, at low temperature (20–60 °C) and for short duration (20–60 min). Different CO2 quantification techniques were employed to assess experiments efficiency and replicability of the adopted quantification techniques. A Design of Experiment was developed to identify the optimum carbonation conditions in terms of time and temperature. The conditions for CO2 content maximisation resulted in a fair agreement with the prediction of the response surface methodology. High values in CO2 uptake (25.1%) and carbonation degree (82%) were achieved, outperforming previous literature studies. Moreover, the mineralisation process significantly reduces the chloride content of CBPD, paving the way for its adoption as a supplementary cementitious material in integrated industrial processes for carbon capture and utilisation.

A Case for the Need to Improve the Unilateral Double Taxation Relief for Estate Duty in South Africa
Authors: Retief Maretha
Published: September 2024

This article aims to address a specific problem statement, namely how the unilateral relief under the Estate Duty Act can be enhanced to alleviate the potential hardship of double estate taxation on cross-border estates. Double taxation is a common occurrence when a person owns properties in more than one country, which become part of their estate at the time of death and liable for estate tax. The limited estate tax treaty network causes countries to reconsider their unilateral relief provisions under their domestic legislation. South Africa faces the same challenge under the Estate Duty Act. This article highlights the areas where clarity is needed in relation to the type of foreign death duty that may qualify for tax relief, such as the scope of qualifying foreign property, the exchange rate applicable and the date on which the conversion should be done, as well as the limitations and conditions of the unilateral relief available under the Estate Duty Act. Insights are provided that could be considered for possible amendments to the Estate Duty Act to provide greater clarity and certainty in calculating the estate duty liability payable in South Africa.

Las Políticas de la Transferencia
Authors:   Instituto Nacional de Bellas Artes y Literatura, Gallardo Núñez Tonatiuh
Published: September 2024

Sostener que el psicoanálisis no puede ser una práctica apolítica parece en la actualidad ser moneda corriente; sin embargo, aun haría falta profundizar en las implicaciones de dicha aseveración (de principio, habría que aclarar que no sería tanto el psicoanálisis como los psicoanalistas los que tendrían que ser el centro de atención). Resultaría esclarecedor para el caso utilizar los modelos clásicos de la doctrina de las relaciones internacionales para empezar a configurar la articulación planteada; pues, si bien en la actualidad superados, en lo que respecta al mundo psicoanálisis permitirían echar luz desde una atalaya distinta. La división, entonces, entre política externa y política interna, por un lado, y la subsecuente fragmentación de esta última en lo que acontece en el ejercicio clínico y lo que se lleva a cabo en las instituciones psicoanalíticas abrirían todo un derrotero de investigación. Desde esta óptica, el fenómeno de la transferencia representa un punto nodal. Para comenzar a zanjar el terreno, en el presente texto me detengo a observar un fenómeno peculiar: la relación que se ha establecido entre la música de Wagner y el Nacionalsocialismo. La música, como fenómeno estético (y, por lo mismo: político), me permitirá a partir de un ejercicio parabólico establecer ciertos puntos de anclaje entre el modelo estudiado y las formas en que la transferencia ha sido gobernada por los psicoanalistas al interior de las agrupaciones (sobre todo las incipientes). A tal grado de poder instituir un concepto que bien podría echar luz sobre lo que sucede en la actualidad: la policía de la transferencia.

En proyectos de construcción, los cambios continúan presentándose como un desafío que influye en el desarrollo normal y el éxito de los procesos de construcción y etapas de ejecución. La mayoría de estos cambios se deben a eventos y causas que, en muchos casos, podrían haberse evitado. En esta investigación, a través de una metodología cualitativa y documental, se realizó una extensa revisión teórica de las causas del cambio y los impactos en costos y tiempo, los cuales, una vez analizados y filtrados, permiten describir y presentar las causas más importantes y sus impactos a nivel general. De igual manera, en el desarrollo de la investigación, se validó la clasificación y el nivel de importancia de estos tipos de cambios y causas mediante la implementación de un instrumento de recolección, contrastando así los hallazgos de la revisión con el contexto real del sector de la construcción en Colombia. Esta información permitió la generación de un modelo para la generación de alertas tempranas con el fin de prevenir estos cambios en la etapa de ejecución del proceso de construcción.

Published: September 2024

Background: Advanced maternal age decreased success of pregnancy rate in the assisted reproductive technology (ART) treatment. We aimed to investigate the association between age and miscarriages in women who required ART for conception.
Methods: A cohort study was conducted using a 10-year sample of 14,898 pregnancy cycles with ART treatment in Xi’an, China. The effects of women’s age on miscarriage were assessed using Poisson regression models. The threshold effect between age and miscarriage was explored through curve fitting.
Results: Compared with lower than 30 years, the risks of early miscarriage and miscarriage were higher in the older age groups (early miscarriage: [35-37 years: RR=1.48, 95% confidence interval (CI): 1.26 to 1.74; ≥38 years: RR=2.25, 95% CI: 1.87 to 2.72]; miscarriage: [35-37 years: RR=1.45, 95%CI: 1.24 to 1.69; ≥38 years: RR=2.17, 95%CI: 1.82 to 2.60]). The nonlinear relationship between age and early miscarriage and miscarriages were observed. The risk of early miscarriage and miscarriage rapidly increased with age after the turning point (age=33 years) (<33 years: [early miscarriage: RR=1.02, 95% CI: 1.00 to 1.04; miscarriage: RR=1.02, 95% CI: 1.00 to 1.03]; ≥33 years: [early miscarriage: RR=1.11, 95% CI: 1.08 to 1.13; miscarriage: RR=1.10, 95% CI: 1.07 to 1.13]).
Conclusion: Among pregnancy cycles undergoing ART, advanced age is associated with higher risk of early miscarriage and miscarriage, and nonlinear relationship between age and early miscarriage and miscarriage were found. More attention should be paid to the risk of pregnant women with older than 33 years in ART treatment.

Published: September 2024

Background: We aimed to explore the role of C-X-C motif chemokine ligand 12 (CXCL12) and cytokine-cytokine receptor interaction signaling pathway in the radiotherapy and chemotherapy resistance as well as cell stemness in colorectal cancer (CRC).
Methods: Bioinformatics analysis was used to identify the differentially expressed mRNAs and signal pathways closely related to differentially expressed mRNAs have also been analyzed in March 2022 at the Jinhua Central Hospital, China. Then, the expression of CXCL12 was detected by qRT-PCR in colorectal cancer cells and testing the effects of transfecting CXCL12 into different CRC-derived cell lines. The effects of CXCL12 on cell proliferation were evaluated by chemosensitivity assay and radiation sensitivity assay.
Results: Bioinformatics analysis of DEGs found a total of 2429 differentially expressed genes, THBS3 and CXCL12 genes are two abnormally highly expressed genes in the CRC. KEGG analysis showed the correlative signaling pathway, cytokine-cytokine receptor interaction, which is related to cell stemness. Furthermore, the expression of CXCL12 in CRC cells was detected and an increasing trend was obtained in CRC cells. In addition, the chemosensitivity and radiotherapy tolerance were elevated after transfected with CXCL12.
Conclusion: CXCL12 could be a potential promote biomarkers in CRC and also promote the chemosensitivity and radiotherapy tolerance.

Background: Glioblastoma multiforme (GBM) is one of the most invasive types of brain cancer. LncRNAs can be considered a new prognostic and diagnostic biomarker in GBM. This study comprehensively explored the interaction of lncRNAs with mRNAs in the TCGA database and proposed a novel promising biomarker with favorable diagnostic and prognostic values.
Methods: The public data of RNA-seq and related clinical data were downloaded from the TCGA database. Differential expression analysis was conducted in R. GO and KEGG signaling pathways were used for enrichment. The STRING database was used for PPI analysis. CE-network was constructed by STAR database. Kaplan-Meier survival analysis and ROC curve analysis to indicate the biomarkers' diagnostic and prognostic values.
Results: Differentially expressed data illustrated that 4428 mRNAs were differentially expressed in GBM. The GO and KEGG pathway analysis showed that the differentially expressed mRNAs were enriched in critical biological processes. The PPI showed that WEE1, BARD1, and CDK6 were the important PPI hubs. The ceRNA network data demonstrated critical lncRNAs. The data revealed that the lncRNA CRNDE, LINC00957, AC072061.1, AC068888.1, and DBH-AS1 are potential diagnostic prognostic biomarkers in the GBM patients.
Conclusion: Altogether, we demonstrated lncRNA, and mRNA interaction and mentioned regulatory networks, considered a therapeutic option in GBM. In addition, we proposed potential diagnostic and prognostic biomarkers for the patients.

Background: Nowadays, blended learning in medicine (BLM) has gained the attention of most experts as an invaluable approach to improving the quality of medical education. The level of attention to articles in this field on social networks is substantial. This study aimed to study the effectiveness of published articles in blended learning, indexed in Scopus and Web of Science databases between 2013 and 2022, from an altmetrics perspective.
Methods: The research is descriptive-analytical, with a scientometrics approach (using the Altmetrics index). The population includes all the articles on blended learning in medicine, indexed in Scopus and Web of Science databases, two well-known citation databases worldwide. Data were extracted using the Altmetrics bookmarklet tool and analyzed with descriptive statistics methods in Excel software.
Results: Out of 1327 articles, 136 articles (10.25%) did not have a digital object identifier (DOI) or PMID number. Mendeley, X (previously Twitter), and Dimensions were the most widely used social networks in blended learning. The United States, the United Kingdom, and Australia had the highest number of tweets in blended learning in medicine.
Conclusion: The number of articles with altmetrics indicators, categorized by publication year, demonstrates an improvement in the familiarity and use of social media by blended learning researchers in medicine. Blended learning researchers are advised to carefully select reputable journals - preferably with DOI - to increase the visibility and attention to their articles on social media.

Background: Natural killer (NK) cells play a critical role in the pathogenesis of endometriosis. Moreover, a normal vitamin D level is remarkably associated with an optimal immune response. So, there may be a probable relationship between these factors and the endometriotic women.
Objective: This study aimed to evaluate the percentage of NK cells and their subsets and their relationship with serum levels of vitamin D and interferon-gamma (IFN-γ) in women with endometriosis.
Materials and Methods: In this case-control study, 29 women with stage III-IV endometriosis and 30 healthy controls were enrolled. The study was conducted in the Immunology Department of Isfahan University of Medical Sciences, Isfahan, Iran between November 2021 and June 2022. The percentage of NK cells and their subsets, including CD56dim CD16+, CD56bright CD16- and CD56bright CD16bright were measured in the peripheral blood samples using flow cytometry. Serum levels of vitamin D and IFN-γ were also measured using the enzyme-linked immunosorbent assay.
Results: The mean percentage of NK cells in women with endometriosis increased significantly compared to the control group (p = 0.03). The percentage of CD56dim CD16+ (p = 0.007) and CD56bright CD16 bright (p = 0.043) increased significantly in women with endometriosis in comparison with the control group, but the percentage of CD56bright CD16- subset was not significantly different. No relationship was observed between NK cells and their subsets with vitamin D and IFN-γ in the studied groups.
Conclusion: The study of NK cell subsets and their related factors can be useful in assessing and treating women suffering from endometriosis. However, more comprehensive studies are required to draw definitive conclusions about these observations.

Background: The lack of improvement in some endometriotic people’s pain after surgery even while using hormone treatment may suggest an inappropriate response to routine hormonal therapies.
Objective: This study aimed to determine a cut-off point for selecting the most appropriate treatment based on the hormone receptors of endometriotic lesions.
Materials and Methods: In this cross-sectional study, by reviewing the medical records of participants and testing their archive samples and phone interviews (if needed), 86 symptomatic women after endometriosis surgery who were operated into governmental hospitals, Shahid Faghihi and Hazrate Zeinab Shiraz Iran were enrolled between March 2017 and March 2019. Women were divided into 2 groups: responsiveness (n = 73 for dysmenorrhea, n = 60 for dyspareunia) to medical treatment and surgery, and unresponsiveness (n = 13, n = 7). We examined the pathological slides of 86 women to determine the amount of hormone receptors and the relationship between the type of medical treatment and the level of hormone receptors on pain relief within 1 yr after surgery.
Results: Based on the receiver operating characteristic curve, dysmenorrhea in the presence of tissue estrogen receptors > 60% (p = 0.1065), and dyspareunia in the presence of tissue progesterone receptors > 80% (p = 0.0001) responded well to medical treatment after surgery. In the presence of endometrioma-dysmenorrhea showed the best response to oral contraceptive pills (69.4%), while in deep infiltrative endometriosis-dyspareunia showed the best response to progesterone treatment (75%).
Conclusion: Prescribing an appropriate hormone therapy based on a specific immunohistochemistry staining pattern can improve the life quality of postoperative endometriosis individuals.

Aim: Age is a known risk factor for cardiovascular disease and plays a role in the atherosclerotic process. The purpose of this study was to look at the impact of aging and associated risk factors on the ultrastructure of internal thoracic arteries in patients undergoing coronary artery bypass grafting.
Material and Methods: We enrolled 27 patients undergoing elective coronary artery bypass grafting at our institute between August-October 2018. Age groups were classified into three: 50-59, 60-69, and 70-79 years. A 2-mm distal portion of the vessel was excised when the ITA was surgically harvested. Transmission electron microscopy was used to investigate the ultrastructural changes. Cell structure, tissue edema, and endothelial mitochondria were all assessed and rated by using semiquantitative analysis.
Results: The ultrastructure of the vessel wall exhibited no significant changes in Group-I. Endothelial wall irregularity with endothelial cells of varying thickness was seen in Group-II. Group-III showed subendothelial edema and localized endothelial wall discontinuity. These changes were particularly severe in the elderly and patients with comorbidities. The greatest permanent cell alterations, such as massive vacuoles and organelle loss, were identified in two patients with kidney failure and hypertension. The average scores assessing the severity of changes in endotohelial cell structure (P  .001), tissue edema (P  .001), and mitochondria (P  .001) were significantly different between groups showing more severe changes with aging.
Conclusions: In elderly patients with comorbidities, the ITA endothelium may exhibit severe ultrastructural alterations, with the most permanent abnormalities reported in those with hypertension and kidney failure. However, The ITA remains the gold standard in CABG with its native resistance to atherosclerosis.
