Authors: R. Selvapriya , M. Gopinath , D. Velmurugan , P. Tamilchelvan
Published: July 2024

The plastic limit analysis of structures has several benefits, but it also has certain disadvantages, such high computing costs. In the past twenty years, plastic limit analysis has performed better thanks to metaheuristic algorithms, particularly when it comes to structural issues. Graph theoretical techniques have also significantly reduced the process's processing time. But until recently, the iterative process and its proportional computer memory and time have proven difficult. In order to quickly ascertain the collapse load factors of two-dimensional frames, a metaheuristic-based artificial neural network (ANN), which falls under the category of supervised machine learning techniques, has been utilized in this work. The numerical examples show that the accuracy and performance of the suggested method are adequate.

Authors: Jiao Roger , Zou Feng
Published: July 2024

This chapter introduces a lightweight quantum-inspired genetic algorithm (LQIGA) to tackle the challenges of workforce scheduling in supply chain and logistics operations, with a specific focus on outsourced workforce scheduling. LQIGA employs a novel lightweight qubit encoding approach, derived from quantum-inspired evolutionary algorithms (QIEA), to effectively represent complex problem constraints while maintaining flexibility. Experimental results on benchmark instances from CSPLib demonstrate the efficacy of LQIGA in consistently achieving optimal or near-optimal solutions within reasonable timeframes. Despite its lightweight nature potentially limiting control flexibility, particularly for larger-scale problems, the promising performance of LQIGA warrants further exploration. Additionally, future research directions, including quantum-inspired parallel annealing with analog memristor crossbar arrays, are discussed, highlighting the transformative potential of quantum-inspired computation in reshaping workforce scheduling and optimization in supply chain and logistics operations

FORMACIÓN INICIAL DOCENTE E INCLUSIÓN
Authors: Sánchez-Huete Juan Carlos , Díaz-Pino Alejandra Alexia
Published: July 2024

Garantizar una educación inclusiva, equitativa y de calidad para todos los países es una de las metas de la Agenda 2030 para el Desarrollo Sostenible (Organización de las Naciones Unidas, 2015). Para ello, un requisito imprescindible es contar con docentes preparados para promover la inclusión en la escuela y, aunque el profesorado reconoce la importancia del tratamiento inclusivo de la diversidad y demanda una formación que lo posibilite, distintos estudios muestran que a lo largo de los años parte del profesorado desarrolla concepciones que dificultan esta práctica. Así pues, resulta pertinente llevar a cabo iniciativas que fomenten la reflexión del docente, ya desde su formación inicial, y realizar estudios, como el presente, cuyo objetivo sea indicar enfoques y métodos que posibiliten el desarrollo de habilidades reflexivas. El diseño de programas de intervención basados en habilidades metacognitivas adaptativas a través de recursos de simulación se posiciona como una opción prometedora.
EDUCAÇÃO ESPECIAL VERSUS EDUCAÇÃO INCLUSIVA
Authors: Sánchez-Huete Juan Carlos , Díaz-Pino Alejandra Alexia
Published: July 2024

Versus é uma preposição que, em latim significava 'para', mas adquiriu no linguajar jurídico inglês, no século XV, o valor de 'contra', e neste sentido é frequentemente usada na língua espanhola de nossos dias. E essa é a questão, de esclarecer se a educação especial deve se direcionar para a educação inclusiva; ou se os dois modelos devem se enfrentar, um contra o outro; ou, pelo contrário, a educação especial e a educação inclusiva são modelos que devem confluir/juntar-se e ser integrados em uma escola que assuma como paradigma as necessidades educativas de qualquer tipo. O objetivo desta chamada temática é gerar um espaço de reflexão que gire em torno desses dois modelos de escola que, nos últimos tempos, vêm provocando o debate sobre se um deve prevalecer sobre o outro. A Educação Especial é entendida como o conjunto de conhecimentos científicos e intervenções educacionais, psicológicas, sociais e médicas que visam otimizar as possibilidades dos sujeitos excepcionais. Os países europeus estão adaptando a Educação Especial de acordo com os princípios de normalização, integração e inclusão, e com a concepção de educação como um serviço prestado ao cidadão. O conceito de Necessidades Educativas Especiais centra-se nos problemas dos alunos, não tendo como ponto de partida as limitações deles, mas focando-se na disponibilização de meios para alcançar as mesmas capacidades para todos. A "Declaração Mundial sobre Educação para Todos" (Jomtien, 1990) é a origem da educação inclusiva: Muda-se do conceito de normalização das diferenças nas escolas comuns para o conceito de escola inclusiva, que aceita todos os alunos como basicamente diferentes, sejam quais forem as circunstâncias pessoais e sociais de cada um deles. A "Conferência Mundial sobre Necessidades Educativas Especiais", organizada pela UNESCO em Salamanca (1994), marca o início do Movimento de Educação Inclusiva, com uma declaração de princípios sobre as pessoas com necessidades educativas especiais, que devem ter acesso às escolas normais (comuns/regulares) e ser integradas em uma pedagogia centrada na criança capaz de atender a essas necessidades. O verdadeiro desafio da educação inclusiva supõe um trabalho que parte do reconhecimento da diversidade humana, da singularidade de cada indivíduo e da sua pertença a uma cultura. A Escola Inclusiva é uma exigência ética e social onde é garantida a aprendizagem de todos os alunos, com especial destaque para os excluídos, marginalizados ou em risco de o ser, através da implementação de um conjunto de ações orientadas a minimizar as barreiras que limitam a aprendizagem e a participação dos alunos.
VISUAL CULTURAL PRACTICES OF POSTCOLONIAL ELITE SCHOOLS IN GLOBALIZING CIRCUMSTANCES
Authors: McCarthy Cameron
Published: July 2024

In this article the author reports on the matter of the contemporary management and conservation of histories in the visual domains of three postcolonial elite school sites: Old Cloisters in Barbados, Rippon College in India, and Straits School in Singapore. These schools form part of a 5-year, 9-country study of postcolonial elite schools in globalizing circumstances—a flash point of articulation between these schools and profound change. The article turns on this fundamental fact: that these schools, which are the products of societies marked historically by British colonial and imperial encounters of the eighteenth and nineteenth centuries and the first half of the twentieth, are now driven forward by new energies associated with marketization, neoliberalism and globalization as these countries lurch forward unevenly towards a postdevelopmental era. This turn towards neoliberal globalization has precipitated radically new needs, interests, desires, capacities and competitive logics among the middle class and upwardly mobile young and their parents in each of these societies that then press powerfully onto these elite schools, and their cultivated pasts as they reside in school anthems, flags, emblems, banners and rituals of assembly, formal dress and decorum. All of this is taking place in the glow of digitalization as these schools increasingly move online locating themselves in photo and video-sharing websites such as YouTube, Facebook and Flicker as well as websites that each individual school is creating to consecrate school heritage. In what follows, then, the author calls attention to the theoretical significance and practical dimensions of the work that these select schools are doing on their rich heritages and historical archives in response to the new demands of globalization and transforming educational markets.

Published: July 2024

A Educação Matemática Inclusiva se constitui enquanto campo científico em constante reflexão e é discutida neste artigo na perspectiva da teoria histórico-cultural, que considera as necessidades geradas pela participação social de todos os estudantes como propulsoras de aprendizagem e desenvolvimento, incluindo o público-alvo da Educação Especial. Este estudo apresenta contribuições de pesquisas desenvolvidas no Programa de Pós-Graduação em Educação em Ciências e Matemática (EDUCIMAT), do Instituto Federal do Espírito Santo (Ifes), junto a estudantes com deficiência intelectual. Para isso, apresenta uma contextualização sobre a inserção desses estudantes nas escolas brasileiras e as necessidades investigativas nos processos de ensino e aprendizagem frente ao cenário educacional. Utilizou o mapeamento como opção metodológica apresentando as pesquisas mapeadas e suas características bem como aproximações e particularidades decorrentes das análises dos resultados obtidos nessas investigações. Como pontos de contato destacam-se a teoria histórico-cultural, o fator motivacional, a utilização de jogos e materiais manipuláveis e, particularmente, a confecção de produtos educacionais por meio da interação social. A Educação Especial precisa ser aporte às especificidades dos estudantes que demandam acompanhamento especializado, mas é a busca por práticas inclusivas no contexto da sala de aula que caracterizará a Educação Inclusiva e, neste campo, a Educação Matemática Inclusiva.

Published: July 2024

O artigo tem como objetivo analisar as metas das Diretrizes Curriculares para Educação Escolar Quilombola e entender essas práticas através das narrativas do Quilombo Sítio Alto em Simão Dias/SE. A metodologia será a revisão bibliográfica da Resolução N° 8 de 20 de novembro de 2012, documento normativo deliberado na reunião do Conselho Nacional de Educação, que estabeleceu normas para a Educação Escolar Quilombola. Como também teceremos uma escrevivência com técnicas da história oral junto à três quilombolas do Sítio Alto, para pensarmos os desafios enfrentados para efetivação da Educação Escolar Quilombola realizadas no chão do quilombo. O conceito de quilombo ficou por muito tempo preso à fuga de escravos até a abolição da escravatura, por isso usaremos o conceito de quilombo de Maria Beatriz Nascimento (2020). Conclui-se que a resolução foi uma tentativa de melhorar os acessos ao direito à educação dos povos quilombola fundamentada na história, memória e ancestralidade negra. Os desafios são enormes pelo passado histórico do Brasil ser pautado em teorias raciais e estereótipos brancos. Por isso precisamos de mais políticas públicas que desenvolvam ações afirmativas para que na prática, os povos remanescentes de quilombo possam ter uma educação feita com eles e não apenas para eles.
EL PASO MÁS ALLÁ DE LA INTELIGENCIA, EN LA FILOSOFÍA PRIMERA DE ARISTÓTELES
Authors: Ibarra Figueroa Williams , Pérez Valdés Ricardo
Published: July 2024

Comprender los procesos mentales en pleno siglo XXI requiere volver a dialogar con quienes buscaron en la πάθος (pasión), τὸ θαυμάζειν (el asombro), el thaumazein, la búsqueda de todo ἀρχή (principio), implicados en conocimientos de diversa índole, en marcados en la noción de physis y en el saber humano en general. Por ello la necesidad de dialogar con autores del mundo clásico griego, en especial con quien sentara las bases de la búsqueda de un espiteme (ciencia) primera, como lo fue Aristóteles en su obra ΤΩΝ ΜΕΤΑ ΤΑ ΦΥΣΙΚΑ Α. Pues resulta crucial este diálogo en el tiempo para indagar en la dimensión del pensamiento aristotélico, que se viene en constituir en un entramado de relación para fundar la pervivencia de su pensamiento. Consideramos axial este diálogo para valorar el quehacer de la filosofía y el pensamiento crítico para la condición humana, para revisar la relación entre “filosofía primera” y la “sustancia divina”, en un constante desafío para la mente humana en el acto de pensar, lo implica el nous, sus consecuencias y su sentido de vivir, habitar y construir el mundo.
EL MITO DEL DILUVIO EN CONTEXTO ISLÁMICO
Authors: Aguiar Maravillas
Published: July 2024

El diluvio es un mitema muy antiguo y persistente. Su origen se remonta a relatos pre-bíblicos asirios y babilónicos. El relato sobre una inundación universal con que el que la divinidad castigó a la humanidad primigenia por su mal comportamiento está presente en la cultura grecolatina, cristiana y también en la cultura islámica. En este trabajo presentamos de qué manera se articula el mito del diluvio en la religión y tradición islámica desde sus inicios hasta época contemporánea. Se concluye que la universalidad del mito del diluvio se comprueba también en el contexto del islam no solo en sus etapas más antiguas, sino en pleno siglo XX con una vigencia fuera de toda duda.

Authors: Ekpemogu Augusta Ijeoma , Abioye Taiwo Ebenezer , Cunningham Chloe Rose , Obolo Rotimi , Anasyida Abu Seman , Ogedengbe Tunde Isaac
Published: July 2024

High strength 7xxx series aluminium alloys are widely utilized in the aerospace, automotive and other manufacturing industries due to their low cost, high specific strength, high stiffness strength and fracture toughness. Additive manufacturing presents new opportunities in producing 7xxx series aluminium alloys such as reduced material waste, shorter lead time, and increased design freedom. This paper reviews the current progress in Wire Arc Additive Manufacturing (WAAM) of 7xxx series aluminium alloys, a technology that offers benefits such as better energy absorption than alternative laser-based processes, high deposition rates, and unrestricted build size. A classification of the AM processes utilized to fabricate aluminium alloys and WAAM process variants for fabricating aluminium alloys are introduced. Also, some common defects including porosity, solidification cracking and volatile elements loss encountered during the WAAM process of 7xxx series aluminium alloys are discussed. Whilst porosity remains a major issue in 7xxx series aluminium alloys produced via WAAM, several opportunities to minimize or eliminate the defects through process selection and alloy development are presented.
Performance Evaluation of Hot Mix Asphalt Modified with Fly Ash and Waste Foundry Sand in Road Development
Authors: Alo Ayopo Bamidele , Oyedepo Olugbenga
Published: July 2024

This research evaluates the performance of hot mix asphalt modified with fly ash and waste foundry sand for road development. Preliminary tests were conducted to determine material properties. Hot mix asphalt samples with varying percentages of granite, sand, stone dust, and bitumen (5%, 5.5%, 6%, 6.5%, and 7%) were produced using ASTM D6927 Marshall mix design. The optimum bitumen content (OBC) was found from the mix to be 5.7%. Using the same mix design, bituminous mixtures were created with waste foundry sand as a partial replacement for fine aggregate (10% - 50% at 10% intervals), along with granite, stone dust, and 5.7% bitumen (OBC). The mix with 40% replacement performed optimally. A new mixture, incorporating granite, sand, fly ash (10% - 60% replacement for filler material, at 10% intervals), and 5.7% bitumen (OBC), was produced. The optimal replacement percentage was 50%. A combination mix of the materials, based on derived optimums, achieved a stability value of 26.09 kN, meeting the Asphalt Institute's criteria. Microstructural analysis indicated a densely packed agglomeration of particles, implying good strength properties. This research demonstrates the viability of waste foundry sand and fly ash as alternative materials, enhancing the strength and flexibility of hot mix asphalt. Reusing these waste materials in road construction is a positive step towards sustainability.
Characterisation and Comparative Insulating Efficiencies of Wood Sawdust and Rice Husk in Glass Shavings Reinforced Termite Clay-Based Composite
Authors: Olayiwola Moses Azeez , Folorunso Davies Oladayo , Tanimola Moses Oladejo
Published: July 2024

The characterisation and insulating efficiencies of sawdust and rice husk in glass shavings reinforced termite clay-based (GSRTC) composite has been compared. Termite clay was unearthed from the Federal University of Technology, Akure (FUTA) campus in Ondo State. It was processed to obtain 150 μm undersize. Glass shavings were processed to obtain 106 μm undersize. The glass shavings were then mixed with the termite clay in a constant weight proportion of 10%. Sawdust and rice husk were processed to obtain 150 μm undersize. The prepared blended GSRTC powder was mixed with the sawdust, and the rice husk in 2, 4, 6, 8, and 10 wt.%. The resulting mixtures were compacted into cylindrical-shaped samples. The samples were dried and fired in a furnace at 1000°C for 2 hours. The chemical composition of GSRTC composite constituents was studied prior to the production of the composite. The control sample with only 10 wt.% of glass shaving possessed the highest: compressive strength; linear and volumetric shrinkage; bulk density; and thermal conductivity, while the sample with 10 wt.% of sawdust in GSRTC possessed the lowest: compressive strength (1.62 MPa); linear and volume shrinkage; bulk density (0.68 g/cm3); thermal conductivity (0.23 W/m-K).. Conclusively, the additive proportion and type affect composites' physical properties. An increase in additive proportion is accompanied by an increase in porosity, a reduction in porosity and bulk density. The compressive strength and thermal conductivity decreased with increasing additive content. GSRTC composites with sawdust additive possessed better insulating performance. However, GSRTC composite with rice husk additive displayed higher compressive strength.

Published: July 2024

Municipal solid waste management continues to be an enormous challenge for developing countries such as Nigeria. With a rapidly increasing population and change in consumption choices in urban cities in Nigeria, the need to cater for and properly manage the increased volume and more diversified waste generated becomes an urgent issue for consideration. Storage and Collection of generated waste make up the crucial elements of waste management systems in any city. Sadly, though, just about a quarter of waste generated in Nigeria is collected. This paper compiles relevant information from recent studies made by researchers and authors on waste management systems in Nigeria to review the current state of the waste storage and waste collection systems in major cities in Nigeria using Lagos and Abuja as case studies. This study also summarizes the methods majorly used for the storage and collection of waste in Nigeria, making recommendations as and when necessary.

Published: July 2024

This study presents a comprehensive investigation into the preparation and characterization of PCL/EA cellulose composites. The Fourier-transform infrared (FTIR) spectroscopy results confirm the successful composite fabrication, indicating the absence of chemical reactions during melt-compounding. Scanning electron microscopy (SEM) revealed distinct morphologies, with PCL forming a continuous phase and EA cellulose exhibiting a fibrous network. Despite successful embedding of EA cellulose fibers in the composite, fractured surfaces indicated poor interfacial interaction, potentially leading to fiber pull out. Thermogravimetric analysis (TGA) revealed enhanced thermal stability in the composites, while differential scanning calorimetry (DSC) indicated minimal impact on PCL melting behavior. X-ray diffraction analysis (XRD) further demonstrated enhanced crystallinity in the composites, highlighting increased order in PCL crystals. Mechanical testing revealed a modest increase in stiffness attributed to the rigid cellulose fibers. However, a decrease in yield strength, tensile strength, and elongation at break suggested reduced ductility and inferior mechanical properties, consistent with poor interfacial adhesion observed in SEM. Overall, this study contributes valuable insights into the structural, thermal, and mechanical characteristics of PCL/EA cellulose composites, offering a foundation for potential applications in various fields.

Background: Patients with chronic ankle instability (CAI) demonstrated altered movement patterns during unanticipated landing compared to coper patients. Understanding the effects of kinematics, dynamics and energetics on individual movement patterns during landing could enhance motor control strategies for patients with ankle sprains while avoiding the transition of coper patients to CAI patients. Therefore, the purpose of this study was to investigate the differences in movement patterns of coper patients compared to CAI patients during the unanticipated landings; Methods: Fifteen individuals with CAI (age: 22.8±1.4 years; height: 180.1±4.2 cm; weight: 81.5±5.8 kg) and fifteen copers (age: 23.1±1.2 years; height: 179.8±4.4 cm, weight: 80.4±6.2 kg) participated in an unanticipated landing task, during which three-dimensional motion capture, ground reaction force (GRF), and muscle activation data were collected. A musculoskeletal model was used to estimate muscle force and joint power among these two groups. Joint power was calculated as the product of angular velocity in the sagittal plane and joint moment data, reflecting the energy transfer at the ankle, knee, and hip joints. Furthermore, energy dissipation and generation within these joints were determined by integrating specific regions of the joint power curve; Results: Individuals with CAI demonstrated a greater muscle force in the vastus lateralis compared copers during the unanticipated landing task, while copers exhibited higher peak muscle forces in the medial gastrocnemius (p=0.007), lateral gastrocnemius (p=0.002), soleus (p=0.004). The muscle activation patterns of CAI patients also differ from those of coper patients. Compared to copers, CAI patients exhibit earlier activation of the rectus femoris (p<0.001) and lateral gastrocnemius muscles (p=0.042). Conversely, copers demonstrate earlier activation of the soleus (p=0.004) and medial gastrocnemius (p=0.003) muscles. In addition, joint power in CAI individuals during unanticipated landing shifted from the ankle to the knee and hip (p<0.001); Conclusions: These findings suggest that individuals with CAI exhibit a change in motion control strategy during unanticipated landing tasks. The variations in peak forces and the ability of proximal muscles to generate force might enable them to offset the deficits noted in distal muscles. Energy redistribution issues observed in CAI patients may help to prevent the transition of coper patients towards developing CAI patients.
Friction Extrusion Spot Welding of Aluminium Alloy: A Comparative Assessment of Top and Bottom Plate-Extrusion
Authors: Ojo Olatunji Oladimeji , Oluwale Ayodeji Olumide
Published: July 2024

This paper integrated two severe plastic deformation methods, namely frictional extrusion, and friction stir spot welding to obtain synergetic benefits and create a friction extrusion spot welding (FESW) process. The FESW process was carried out with the use of AA1xxx Al alloy by interchanging the location of the predrilled extrusion hole (between the upper and bottom plates). The microstructure, tensile-shear load, and fracture behaviours of the welds were investigated. The results revealed the presence of no weld discontinuities/flow-aided defects while the FESW process was effective in filling the extrusion holes irrespective of the location of the predrilled holes. An inverse relationship was found to ensue between the tool’s rotating speed and the tensile-shear load of the bottom plate hole-friction extrusion spot welded joint joints while a direct correlation occurred between the tensile-shear load and the rotational speed (up to 1100 rpm) in the top plate hole-friction extrusion spot welded joints. The difference in the tensile and fracture behaviours of the two weld categories is attributed to the disparity in the hole-filling mechanisms. The maximum tensile shear load of 3.1 kN (at 710 rpm) and 3.3 kN (at 1100 rpm) were obtained in the bottom plate hole-and top plate hole-FESW joints respectively.

In view of the growing concern over the threat of antibiotic resistance and bacterial infections, this study evaluated the antimicrobial performance and characteristics of chitosan/polyvinyl alcohol (PVA) nanofibers incorporated with Methylene Blue (MB). Following the fabrication of chitosan/PVA nanofibers loaded with different MB concentrations via electrospinning, the samples were characterised through Field-emission Scanning Electron Microscopy (FESEM), Fourier Transform Infrared (FTIR) spectroscopy, and leaching tests. Finally, the antimicrobial inhibition level of the samples was assessed via the disc diffusion method. Based on the results, the MB-integrated chitosan/PVA nanofibers exhibited a nanoscale morphology, and the FTIR confirmed the presence of MB. The findings also established a positive correlation between the MB concentration and leaching intensity. Furthermore, the optimal antimicrobial efficacy against Escherichia coli was achieved by the chitosan/PVA/MB (5 wt.%) sample with a 2-min laser exposure, which recorded a significant inhibition zone of 8.65 mm. In conclusion, MB demonstrated potent antimicrobial properties against E. coli, suggesting its potential integration in electrospun nanofibers for combating bacterial infections via photodynamic therapy.

Aim

To document changes in the peripapillary vascular network and retinal vascular plexuses in patients with optic neuritis (ON) due to multiple sclerosis (MS) and compare it with healthy individuals.

Settings and design

A prospective comparative case–control study performed at the Ophthalmology Department of a tertiary-level university hospital, between November 2020 and November 2022.

Patients and methods

In all, 26 eyes of 26 patients with ON caused by MS and 26 eyes of 26 sex-matched and age-matched healthy controls. We used optical coherence tomography AngioVue Enhanced Microvascular Imaging System aiming to quantify and compare microvasculature changes in the macula and peripapillary region between the two groups.

Results

We found a statistically significant decrease in the superficial and deep vessel density in the macular area in patients with ON compared with the healthy controls. Superficial vessel density in the macular area in the healthy ones was 49.90±3.4, while in those with MS was 44.09±4.9 (P<0.001). Deep vessel density in the macular area in patients without MS was 51.71±6.8 while in patients with MS was 45.51±5.7 (P<0.001).

Conclusion

There is a decrease in superficial and deep vessel density and radial peripapillary vessel density in patients with ON caused by MS in comparison to healthy controls.
Community Members’ View about Violence against Health Workers: A Qualitative Study
Authors: Al-Mousawi Ali Mousa , Lafta Riyadh K.
Published: July 2024

Background:

Violence toward health-care workers is a global health problem, usually associated with decreased job satisfaction, and poor patient care outcomes, with serious consequences for the patients. Its extent is difficult to measure due to under-reporting.

Objective:

The objective of this study was to explore the opinion of some influential community members about violence against health workers with respect to its types, reasons, mechanisms in place, and suggestions to de-escalate it.

Methods:

A qualitative in-depth study was conducted with 10 key informants (including people working in judicial premises, police and military services, teachers, municipality members, and religious leaders). The discussion was conducted through a direct face-to-face interview, using a semi-structured interview guide that included open-ended questions.

Results:

Almost all the interviewees agreed that the main reasons for violence were the general security instability in the whole country, the poor quality of health services, weakness of laws and regulations for the punishment of the perpetrators, irresponsible behaviors of some doctors, in addition to the unexplained negative role of media toward doctors.

Conclusion:

workplace violence is a common, frequently happening practice in most health-care facilities in Iraq, probably attributed to the long-suffering of wars and conflicts. Shortage of staff and equipment is the base for this malpractice.

Published: July 2024

Background:

Chondrosarcomas (CSs) are the second-most common primary malignant tumor of the bone and are a malignant tumor of cartilaginous origin.

Aim:

The aim of the study was to analyze the accuracy of fine-needle aspiration cytology (FNAC) in diagnosing CS and its correlation with histologic diagnosis and evaluate the survival outcome and prognostic factors in CS.

Setting and Design:

Retrospective study conducted from January 2013 to December 2019.

Materials and Methods:

Data regarding clinical findings, FNAC diagnosis, histopathological, radiological findings, and patient status were retrieved.

Statistical Analysis:

Kaplan–Meier curve and Log Rank (Montel Cox) analysis were used for statistical analysis.

Results:

Twenty-six cases of CS were selected. The accuracy of diagnosing CS on FNAC was 61.53%, and the accuracy in interpreting it as a malignant lesion was 92.30. Overall survival outcome in CS patients was 92.23% at 1 year, 73.23% at 3 years, and 61.32% at 5 years. Survival outcomes significantly altered depending on the histological variants, metastases status, and histological grading, which showed Chi-square values of 31.77 (P ≤ 0.001), 8.43 (P = 0.011), and 6.33 (P = 0.043), respectively. The median survival time of CS was 2214.98 days, with a standard error of 362.83. Patient age, gender, tumor size, and skeletal versus extraskeletal CS had little impact on CS survival (Chi-square value = 0.464 (P = 0.496 NS), 0.570 (P = 0.450 NS), 2.83 (P = 0.242 NS), 0.125 (P = 0.724 NS), respectively.

Conclusion:

FNAC is a beneficial, reliable tool for screening and diagnosing CS. Prognostic factors such as histological variants, histological Grade 1 and 2, and no metastases status are associated with good survival. Patient age, tumor size, and extraskeletal location are not associated with prognosis and survival.
