Traveling wave solutions for an integrodifference equation of higher order
Authors: Wu Fuzhen
Published: July 2022

This article is concerned with the minimal wave speed of traveling wave solutions for an integrodifference equation of higher order. Besides the operator may be nonmonotone, the kernel functions may be not Lebesgue measurable and integrable such that the equation has lower regularity. By constructing a proper set of potential wave profiles, we obtain the existence of smooth traveling wave solutions when the wave speed is larger than a threshold. Here, the profile set is obtained by giving a pair of upper and lower solutions. When the wave speed is the threshold, the existence of nontrivial traveling wave solutions is proved by passing to a limit function. Moreover, we obtain the nonexistence of nontrivial traveling wave solutions when the wave speed is smaller than the threshold.
Computation method of the Hosoya index of primitive coronoid systems
Authors: Oz Mert Sinan , Cruz Roberto , Rada Juan
Published: July 2022

Coronoid systems are natural graph representations of coronoid hydrocarbons associated with benzenoid systems, but they differ in that they contain a hole. The Hosoya index of a graph $ G $ is defined as the total number of independent edge sets, that are called $ k $-matchings in $ G $.

The Hosoya index is a significant molecular descriptor that has an important position in QSAR and QSPR studies. Therefore, the computation of the Hosoya index of various molecular graphs is needed for making progress on investigations. In this paper, a method based on the transfer matrix technique and the Hosoya vector for computing the Hosoya index of arbitrary primitive coronoid systems is presented. Moreover, the presented method is customized for hollow hexagons by using six parameters. As a result, the Hosoya indices of both each arbitrary primitive coronoid system and also each hollow hexagon can be computed by means of a summation of four selected multiplications consisting of presented transfer matrices and two vectors.

Epidemic spread models are useful tools to study the spread and the effectiveness of the interventions at a population level, to an epidemic. The workhorse of spatially homogeneous class models is the SIR-type ones comprising ordinary differential equations for the unknown state variables. The transition between different states is expressed through rate functions. Inspired by -but not restricted to- features of the COVID-19 pandemic, a new framework for modeling a disease spread is proposed. The main concept refers to the assignment of properties to each individual person as regards his response to the disease. A multidimensional distribution of these properties represents the whole population. The temporal evolution of this distribution is the only dependent variable of the problem. All other variables can be extracted by post-processing of this distribution. It is noteworthy that the new concept allows an improved consideration of vaccination modeling because it recognizes vaccination as a modifier of individuals response to the disease and not as a means for individuals to totally defeat the disease. At the heart of the new approach is an infection age model engaging a sharp cut-off. This model is analyzed in detail, and it is shown to admit self-similar solutions. A hierarchy of models based on the new approach, from a generalized one to a specific one with three dominant properties, is derived. The latter is implemented as an example and indicative results are presented and discussed. It appears that the new framework is general and versatile enough to simulate disease spread processes and to predict the evolution of several variables of the population during this spread.
La mentalidad suntuaria de la corte imperial de Felipe IV en las novelas de María de Zayas
Authors: Garrido Ardila J. A.
Published: July 2022

Las novelas de María de Zayas se han venido leyendo como literatura eminentemente feminista que ensalza el valor y las capacidades de las mujeres al tiempo que, de hito en hito, menoscaba a los hombres. Este artículo propone leer las novelas integradas en Novelas amorosas y ejemplares (1637) y en Desengaños amorosos (1647) como literatura que celebra los modos de vida suntuarios en la corte de Felipe IV, precisamente en los años posteriores a la imposición de pragmáticas reales contra el lujo. A tal fin, procedemos en tres tiempos: 1) destacando el perfil aristocrático de Zayas, 2) matizando las tesis feministas sobre su obra, y 3) demostrando mediante un análisis textual que en sus novelas, especialmente en el marco narrativo de Lisis, se incide y se exalta el lujo y el refinamiento de la aristocracia en la corte imperial de Felipe IV. En función de este análisis se concluirá que las novelas de Zayas comportan una glorificación de la clase noble asentada en la corte.
Los poemas de Manuel Machado en El Álbum Ibero Americano (1891-1893)
Authors: Alarcón Sierra Rafael
Published: July 2022

Manuel Machado publica seis poemas en El Álbum Ibero Americano entre diciembre de 1891 y enero de 1893, de los cuales tres son desconocidos, lo que no había sido señalado por sus críticos ni había sido recogido en ninguna bibliografía. Son, además, las primeras composiciones que publica su autor, adelantando en un año a los «Cantares» que aparecieron en el Almanaque de Don Quijote para 1893 y a sus colaboraciones en La Caricatura a partir de julio de 1893. En este artículo transcribo, analizo y contextualizo estas aportaciones.

Leyes contra Natura. Los subterfugios del realismo en Bodoque de Mercedes Formica
Authors: Soler Gallo Miguel , Gala Candelas
Published: July 2022

A lo largo del presente artículo analizaremos la novela corta Bodoque de Mercedes Formica (1913-2002), una de las voces más desconocidas del panorama literario español de posguerra, a pesar del notable éxito que en su época ostentó. La obra en cuestión es de las primeras de su trayectoria literaria y su temática resulta singular respecto a otras creaciones de los años cuarenta y cincuenta. Tras la apariencia de estar contando una simple historia, Bodoque oculta un subtexto altamente subversivo que revela la agudeza de la escritora quien, como abogada que también fue, tiene como principal propósito denunciar las injusticias legales sin alertar o incomodar a la censura, y como escritora, es consciente de las estrategias disponibles en el lenguaje con las que entretejer un complejo texto con serias implicaciones.
Digital Teaching Competence of University Teachers: Levels and Teaching Typologies
Authors: Esteve-Mon Francesc M. , Llopis-Nebot Mª. Ángeles , Viñoles-Cosentino Virginia , Adell-Segura Jordi
Published: July 2022

Today, university teachers need to have not only basic digital skills, but to be able to use technologies in teaching-learning processes, in their professional development and that of their students. This article focuses on analysing digital teaching competence (DTC), and exploring its dimensions based on the self-perception of a sample of 558 teachers from a Spanish university, following the European DigCompEdu framework. According to the results, university teachers perceive themselves to have an intermediate level of DTC. Technical and professional aspects were higher than the pedagogical ones and those that refer to the effect on student’s digital competence. The ANOVA test did not show significant differences in DTC according to the academic position, but it did according to the scientific area. One of the most significant findings is that the DTC would not be a unitary construct; after the factorial analysis of the items, three categories were obtained that can constitute different teaching typologies: the inspiring teacher, the creator and the tutor. This study provides a new instrument to explore university teachers’ level of DTC and contributes to the debate on this competence by exploring the categories that underlie it, providing data that can be useful both at a scientific level and in the development of practices and policies for teaching improvement.

Published: July 2022

This article presents the development of a “small contraction” sensor fabricated using 3D printing and intended for practical works of biology; with the aim to replace the traditionally used system. This fabricated sensor is then integrated into a Computer Assisted Experiment (CAE) environment. CAE is a teaching technology that allows the students to carry out the acquisition and the processing of their data on computer (saving, adding comments, amplification…). The combination of these two technologies (CAE and 3D printing) has made it possible to equip low-cost multipurpose labs requiring minimal maintenance and where the work space is standardized. The result of a survey conducted with the students at the end of the lab sessions shows that 79.1% of them prefer the use of the new system, given the advantages it offers in terms of better understanding of the practical works objectives, time saving and the data processing functionalities it provides.

Authors: Verawati Ni Nyoman Sri Putu , Ernita Nevi , Prayogi Saiful
Published: July 2022

The difficulty of tutors in all types of learning (face-to-face and online) is when they teach abstract concepts in modern physics courses, especially to improve students' reasoning skills. We see an opportunity that advances in digital technology can help overcome this problem. This study aims to improve the reasoning performance of STEM students in modern physics courses using virtual simulation integrated with the LMS platform. Experimental design was prepared with one control group (face-to-face learning with expository method). The sample was 54 STEM students at the University of Mataram which was divided into the experimental group (n = 27) and the control group (n = 27). Reasoning skills were measured using an essay test instrument, and the results were analyzed descriptively (analysis of increasing reasoning skills scores) and statistically (analysis of differences in reasoning skills scores between sample groups). The results of this study have clearly shown that the reasoning performance of STEM students in modern physics courses can be improved by learning using virtual simulation on the LMS platform. Descriptive and statistical analysis of the reasoning performance of STEM students shows the advantages of learning using virtual simulation when compared to face-to-face learning that relies on expository methods. We recommend using virtual simulation on the LMS platform to teach abstract concepts that are not limited to modern physics but in science learning in general.

Darwin's Causal Argument Against Creationism
Authors: Clatterbuck Hayley
Published: July 2022

In the Origin, Darwin forwards two incompatible lines of attack on special creationism. First, he argues that imperfect or functionless traits are evidence against design. Second, he argues that since special creationism can be made compatible with any observation, it is unscientific and explanatorily vacuous. In later works, Darwin shifts to an argument that he finds much more persuasive and which would undermine theistic evolutionism as well. He argues that variation is random with respect to selection and that this demonstrates that there is no design in the biological world. I examine why Darwin found the argument from independence of variation and selection more compelling than the argument from imperfection. I argue that Darwin utilized general principles of causal inference, akin to those used in modern causal modeling, to rule out any unified cause behind the evolutionary process. 
Setting the Stage for Performance and Accountability Through Expectations
Authors: Sipes Justin M.
Published: July 2022

This chapter stresses the importance of expectations and their role in performance and accountability. In a hybrid work environment, unclear expectations can lead to adverse performance and difficulties with accountability. The chapter encourages the use of dialogue to establish expectations and strategies to that end. Overall, expectations are a process and are dynamic. They need to be revisited often. Shared expectations are a strong foundation that contributes to the clarity of tasks and can enhance performance. They outline accountability, and the practice of developing can make the evaluation of performance easier. As more employees ask for flexible work and more employers are trying to meet these needs, expectations are crucial in establishing environments that maximize performance and accountability.
Where Are We on Diversity, Equity, and Inclusion?
Authors: Gbadamosi Ayantunji
Published: July 2022

Inequity is demonstrated in a plethora of ways. Although it varies in its manifestation from one society to another, the notoriety is global with lingering devastating impacts in many ramifications. Accordingly, it has attracted the attention of various stakeholders on the need to achieve diversity, equity, and inclusion in various walks of life. This chapter examines this in the marketing context. Attention is specifically focused on homelessness, poverty, the disproportionate representation of children in marketing, and gender-based discrimination in marketing to gauge the progress in the quest to bring normalcy and achieve an ethical, equity-based, diverse, and inclusive marketing system. The eclectic review of the extant literature suggests there are still several uncovered gaps in the marketplace in relation to this. The need for strategic direction to address this is highlighted in the chapter.

The COVID-19 pandemic promoted a sudden impact on businesses across the globe, leaving strong concerns about how it will affect SMEs that contribute with 40% of GDP in emerging economies, where they already operate in challenging circumstances due to institutional voids and scarce resources, in a continuous struggle to survive. In this scenario, Brazilian SMEs accelerated their digital transformation (DT) to maintain their economic activity, moving from physical stores to the virtual environment using websites, social networks, and messaging applications, in a context where effective digital inclusion becomes essential, with the effective appropriation of digital technologies. The purpose of this work is to examine in 20 Brazilian SMEs, challenges, strategies, and activities they had faced to deal with this digital transformation. This chapter is expected to fill a gap in literature as studies into SME development through social media are still in the early stages and to be a practical contribution by demonstrating true challenges and results faced in this process.
Advertising in China
Authors: Ozturk Rukiye Gulay
Published: July 2022

Advertising is a multi-million-dollar industry in China. China's progress in production and technology is highly important in that regard. COVID-19 first broke out in China and took hold of the entire world by the end of 2019, which compelled the attention of every country. In this context, as China is a dominant country in the advertising market across the world and is the place where the pandemic broke out, this study aims to examine the most striking ads of this period by offering a linguistic and visual analysis based on the affect dimension of Martin and White's appraisal theory. It was found that the three most frequently used elements in these ads were security, happiness, and inclination. Employment of these three elements in the advertising communication of the brands in the climate of anxiety and fear during COVID-19 has been considered an appropriate strategic approach.
Fashion Design and Production through the Social Economy Lens: Contributions and Challenges for a Holistic Approach
Authors: Melo Beatrice , Beresford Thiago , Broega Ana Cristina
Published: July 2022

The growing environmental crisis and the proliferation of social inequality, with affective ties to the movements of predatory neoliberal globalization, desperately claim for the constitution of a truly sustainable future. To this end, it is essential to implement ethical, empathic, and cooperative behaviors and the reorientation of the market to consider the coexistence of human beings with nature in harmony. In this context, the global fashion system, characterized by mass production, low cost, and promoting excessive disposable consumption, devalues the natural diversity of the biosphere - from the extraction of raw materials to waste produced in the post-consumption - and contributes, directly and exponentially, to aggravate social inequalities and fracture, increasingly, the imbalance of ecosystems. The concept and practices of the Circular Economy have often been addressed to implement a sustainable production chain; however, it still neglects the social and cultural dimensions. Founded on the fashion production chain processes and their impacts on the lives of those who manufacture garments, on the community and environment in which we live, the purpose of this article is to present a sustainable model for designing and manufacturing fashion products. Social Economy values such as the social development of the people and communities involved, holistic development of the human being, diffusion of feelings of cooperation, respect, solidarity, and commitment, and, above all, ethical behaviors are the groundwork of this study. This framework absorbs characteristics of the Social Economy in the fashion industry and values sustainable human development supported by educational programs for workers, socially responsible sewing workshops, collaborative design, recognition of local knowledge, and social entrepreneurship. Furthermore, this model will empower the wage-earner community that produces fashion by participating in the design and development of apparel products. The methodology used included a literature review and analysis of reports; after identifying critical points of Social Economy theories, this study aims to provide a fairer model for developing products oriented towards the humanization of productive relations, transparency, and sustainability. Despite including SE's humanistic components to fulfill the CE's social gaps, this plan for Social Circularity can only overcome a few of the recurrent problems in fashion production. Standing as an in-progress framework requires both validation and deepening of socio-ecological aspects in implementing a holistic economy in its total multidimensionality.
Designing Textile Surfaces through Additive Manufacturing for Unsighted Individuals
Authors: Marques Susana , Pina Liliana , Lucas José , Duarte Paulo , Miguel Rui , Sampaio Álvaro
Published: July 2022

This paper aims to discuss the use of Additive Manufacturing (AM) to produce textile samples. The goal is to explore different possibilities in the creation of different stimuli regarding textures and scents coming from the application of different types of filaments on different textile surfaces, with different weights and compositions. Considering the application of this technology in fashion products, particularly on clothing, the different textile samples developed, will be evaluated by visually impaired (VI) individuals on further empirical studies. Since unsighted individuals are regarded as more sensitive to tactile and olfactory experiences, it is important to understand their perception regarding AM acceptance. Having into account the perspective of fashion design towards inclusivity, the availability of different sensory inputs in common fashion brands could improve the relationship between visually impaired (VI) consumers and fashion brands. This paper fills the gap in the literature regarding unsighted individuals and their experiences with clothing, especially those using AM technology. Keywords: Additive Manufacturing; textile surfaces; visually impaired individuals;

Published: July 2022

Liquefied adhesive made of oil-palm trunk (OPT) was produced according to bio-refinery concept. In this context, OPT was converted into 20-60 mesh powder and it was converted into liquid via liquefaction process involving reaction of thermo-chemical and resulting in pre-polymer like phenol-formaldehyde (PF). The characteristics were determined based on Indonesian Standard (SNI) 06-4567-1998 for PF resin. The pre-polymer then was used for binding of three composition types of particleboards, namely 100% OPT particle, 50:50 mixture of OPT and jabon wood particles, and 100% jabon wood particle. Evaluation of the board was carried out based on Japanese Industrial Standard (JIS) A 5908-2003 for particleboard. Results of this study exhibited properties of the pre-polymer generally met the SNI except its viscosity was too high. For overcoming this, the pre-polymer was then diluted in solvent until it was appropriate to be placed in spray gun and passed the nozzle for further use as binder. Physical properties of the board showed moisture content (MC) and density fulfilled JIS standard however thickness swelling was up to limit. Mechanical properties of the board showed only modulus of elasticity (MoE) met the criteria of JIS while modulus of rupture (MoR) and internal bonding were below the target. Statistically, two parameters, namely MC and MoE were different among the boards. For sum up, making adhesive from oil-palm stem using bio-refinery method was feasible and it can be applied for particleboard binding.
The Fashion and the City: Porto Case Study
Authors: Guedes Graça , Fernandes Aline Guimarães , Marques António Dinis
Published: July 2022

Fashion, as a simultaneously cultural and global phenomenon, has become an attractive factor in many cities, particularly the large metropolises where it assumes a prominent role, as in Paris, London, Milan, or New York. In countries where fashion does not assume notoriety and global prestige, there is an emergence of fashion movements more associated with local cultural characteristics, which are used by fashion designers as sources of inspiration and differentiation.In major cities, world-renowned designers and brands take on recognized importance, and the attractiveness that fashion districts have on visitors is notorious. In smaller cities, however, generally associated with cultural and artistic heritage, fashion appears in some places as a specific offer, marked by originality and differentiation of historical roots or inspired by local culture. The interest in fashion, in general, leads the management of territories to associate the local dynamics of fashion creation with shopping tourism, creating specific itineraries and infrastructures, in an attempt to follow the example of the big cities and, thus, develop the fashion business by increasing the reasons of interest to visitors.The study aims to analyse the dynamics of development of the fashion business in medium-sized cities with strong tourist attractiveness, to design a territory management model that maximizes the notoriety of local fashion, and stimulates economic activities directly and indirectly related to fashion.

Authors: Pechová Marcela , Vik Michal , Viková Martina
Published: July 2022

The human visual system is able to adapt to a wide range of the adaptive luminance levels. However, the chroma was found to be the most affected attribute in the assessments. Several color appearance models have been proposed to describe adaptation mechanisms and predict the color appearance at different luminance levels. A set of 72 color pairs of samples that surround four color centers with high chroma was prepared to the test the prediction performance of the CAMs. The visual assessment of these color pairs was performed at eight luminance levels including photopic, mesopic and scotopic luminance levels. The data from visual assessment were used to the test prediction performance of six color difference formula and color appearance models, namely CIELAB, CIECAM02, CAM02-UCS, CAM16, CAM16-UCS and CAM16-UCS with power function.

Authors: Kalaitzi Despoina , Papachristou Evridiki , Papadimitriou Spyridon Spiros
Published: July 2022

The paper seeks to unfold the interrelationship and interaction between architecture and fashion disciplines. This research aims to explore ways of introducing architectural and computational tools into design processes of a fashion collection. In terms of methodology, the catalogue of the exhibition “RRRIPP!! Paper Fashion” which describes the history of paper garments was studied, in combination with an analysis of Iris Van Herpens’ parametric dresses via architectural diagrams. Different styles and the development of their patterns were also studied, overcoming the lack of pattern making and anthropometry knowledge that architects could face. A series of experimentations were made, using the paper as the main material. In these experimentations the paper was transformed into a garment that dresses the body via folding techniques, by following: Folding techniques for designers. The results revealed that the body is the main axis of the design process. Based on this conclusion an algorithm was developed, in 3D software platforms, as a solution/tool for the experimentations but also for a broader use from a fashion expert. The algorithm needs as an input the persons’ body measurements, such as the circumference of bust, waist, hips etc. and outputs the digital 3D representation of that specific body. This algorithm converts each different and unique body type into an asset for both exhibitional and design purposes. Α paper garment was finally developed by using the algorithm and the paper models that were the result of the experimentation process. Different folding techniques were applied on the paper that transformed it into a “smart” surface that combines the principles of shape, structure and ornament. The final product proves that architectural tools can cooperate well with the fashion disciplines in order to provide unique results.
Co-Composting Date Palm Tree Wastes and its Effects on Soil Fertility
Authors: Badawi Mohamed A.
Published: July 2022

UAE is one of the world major producer of dates. In 2015, the country had more than 42 million date palm trees and this number is increasing gradually. Every year there is more than 600,000 tons of date palm tree wastes are generated in farms. Since composting of date palm tree wastes is hard and slow, but when mixed with chicken manures it has been improved and time needed for maturation is greatly reduced, and the produced compost has better quality. Amended sandy soil with produced compost showed better physical, chemical and biological properties against control treatment (farm yard manure, FYM). In this experiment we used several treatments e.g chicken manure compost, CMC, and date palm tree composted wastes, DPTCW in different ratios, to evaluate its quality as organic fertilizer and to study its effects on the properties of sandy soils against control, FYM. CMC reached maturation faster than DPTCW and has higher contents of NPK nutrients than DPTWC, while organic matter and humus were different as composting activity performed. Tested sandy soil showed higher organic carbon content and its numbers of microorganisms has been increased in all treatments against control. Date fruits yield was increased in all treatments above control by 27-62% above control.

In textile engineering education alike, innovative teaching methods, for instance, learning through virtual reality [2], learning by making [3], and game-based learning [4] are apt, and in fact, required methods to teach these subjects for Industry 4.0 in a more understandable and holistic way. Specifically, game-based learning is seen as beneficial in textile engineering education in the part of knowledge acquisition, student engagement and independent learning [4]. This paper presents a pilot study about how online textile games (‘ChoiCo’-Choices with Consequences) co-created with industry partners in the scope of an Erasmus+ KA2 project (T-CREPE), have been incorporated into a design engineering course in a university in Belgium. The purpose of this paper is to reflect on the impact of using digital games in textile engineering education and students’ gains from this approach. Ten (n = 10) textile engineering students participated in questionnaires providing quantitative and qualitative data about the games. Also, reflection reports written by students for each game provided personal insights. The results have shown that games can be useful in textile engineering education by improving students’ 21st century skills (e.g., critical thinking, problem solving, self-learning).

Authors: Oliveira Nelson , Carvalho Helder , Cunha Joana
Published: July 2022

The fashion industry market is intrinsically dynamic and mutable. Emerging trends lead consumers and industry to a mindset transformation, through a deep shift in the paradigms of creation, production, and acquisition. The footwear industry recognizes the potential of this reality, focusing on the development of innovative strategies based on collaborative mass customization. In Portugal, despite footwear being a mature industry, it is necessary to continuously invest in innovation-based competitiveness. Thus, based on two surveys, one addressed to a group of seven Portuguese manufacturers (with no mass customization experience), and the other to a group of three Portuguese experts (specialized in footwear customization), critical information about expectations versus reality was gathered. The main objective was to obtain specific and exhaustive data, based on qualitative elements. In this way, it is aimed to contribute to the theoretical reflection of the collaborative design applied to the customization of footwear based on the overview of the Portuguese industry.

Published: July 2022

Digital transformation is changing the textile machinery industry. The growing digital development is breaking down the traditional barriers of the industry, leading to advantages for both the textile machinery enterprises and their customers. Accordingly, many academics and practitioners believe that, in the next years, rethinking the future of this sector in the light of digitalization will be crucial. However, scientific research about digital transformation in the textile machinery industry is lacking. This paper tries to bridge this gap by carrying out a mixed quantitative and qualitative approach through 17 in-depth interviews with a sample of Italian textile machinery companies. The aim of this paper is to provide insights on the level of awareness within the industry and a holistic overview about the main drivers, challenges and opportunities which have to be taken into account towards leveraging of new technologies. Finally, the article suggests some possible developments for further research.
Early Interactions between the Hellenistic and Greco-Roman World and the Chinese: The Ancient Afro-Eurasian Routes in Medicine and the Transmission of Disease
Authors: Solos Ioannis
Published: July 2022

This paper discusses the historical exchanges, communications, and circumstances that initially enabled the opening of trade routes between China and the Hellenistic and Greco-Roman world. In addition, it explains how ancient Greeks first became aware of China, and the original premise of trading silk for horses. Historical Chinese texts are analyzed to identify references to the Hellenistic and Greco-Roman world in an attempt to elucidate the extent of official interactions between the two cultures. Historical and archaeological sources confirm that trade existed for millennia before Western Europeans traveled to China during the Age of Exploration. The thesis describes how silk and disease traveled from east to west and explains the historical conditions that allowed the exchange of ideas, practices, beliefs, and culture.

Abstract

Context:

Cannabidiol (CBD), used in conjunction with other antiepileptics, is gaining interest in managing drug-resistant epilepsy (DRE), which accounts for 10-20% of all childhood epilepsies worldwide.

Aims:

We highlight a first experience of using CBD amongst children with refractory epilepsy in a tertiary care hospital in Pakistan and its possible effect on seizure frequency and associated adverse outcomes.

Settings and Design:

A retrospective review, conducted at a pediatric neurology outpatient clinic at the AKUH, a tertiary care hospital in Karachi, Pakistan.

Materials and Methods:

We assessed children with DRE who were prescribed escalating doses of CBD from June 2019 to October 2020 at Aga Khan University, Pakistan. A descriptive analysis was performed, and improvement in seizure frequency and adverse effects (as reported by caregivers) were measured.

Statistical Analysis Used:

Statistical analyses were performed using IBM Statistical Package for the Social Sciences 21.0.

Results:

CBD was prescribed to 17 patients with DRE with a mean age of 5.52 ± 0.96 years, and 15 of them were boys. The mean baseline seizure frequency was 27.65 ± 3.59 episodes per day. All patients were stabilized on antiepileptics before administration of CBD and were started at an initial dose of 10 mg/kg/day, which was subsequently escalated, where needed. Our results showed that 70.6% of children reported an improvement in seizure frequency. The mean percentage reduction in seizure frequency at 12 weeks was 68.33% ± 7.55 from baseline; seven patients reported more than 75% improvement, and two patients became completely seizure-free. Nine patients reported minimal side effects.

Conclusion:

In this initial experience, we saw an improvement in overall seizure frequency in DRE patients, with tolerable adverse outcomes. The paper highlights an initial potential of using CBD in children with DRE in an LMIC, without drawing any firm conclusions. It highlights the potential for making a bigger change for which adequately designed and powered studies would be needed in such contexts to ascertain the actual impact.

Published: July 2022

Abstract

Background:

Malformations of the central nervous system (CNS) include a wide range of disorders characterized by neurodevelopmental delay and seizures. They are multifactorial in etiology. There is a lack of data in India; hence, this study was planned to study the clinical profile and type of CNS malformations in children.

Materials and Methods:

This is a retrospective chart review of CNS malformation between January 2018 and December 2018. Details of clinical and laboratory data were analyzed.

Results:

Of 110 cases, males were 65. The most common age group was 1–5 years accounting for 50%. Various clinical features were developmental delay (72), seizures (58), microcephaly (57), and dysmorphism (28). History of birth asphyxia was present in 12 cases. The various malformations were neuronal migration defects (36.36%); congenital hydrocephalus (24.54%), with aqueductal stenosis being the most common etiology; neural tube defects (13, 11.8%); and posterior fossa malformation (10 of which two were Joubert syndrome). Others were five cases of agenesis of corpus callosum, one case each of hemimegalencephaly and arteriovenous malformation, and four cases of complex mixed malformations.

Conclusion:

The most common presentation was global developmental delay and seizures. The most common malformation of CNS observed was neuronal migration defect followed by hydrocephalus. They can present as birth asphyxia.
