Published: April 2024

Introduction: Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by inappropriate levels of impulsive behavior, hyperactivity, and/or inattention, with a worldwide prevalence estimated at around 7% in childhood and adolescence, and around 3 % in adulthood, with a higher prevalence in boys than in girls. Objective: It was to present the main clinical implications of adequate nutrition in children and adolescents with attention-deficit/hyperactivity disorder. Methods: The PRISMA Platform systematic review rules were followed. The research was carried out from January to March 2024 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 84 articles were found, 21 articles were evaluated, and 14 were included in this systematic review. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 19 studies with a high risk of bias and 30 studies that did not meet GRADE. Most studies showed homogeneity in their results, with X2=62.8%>50%. Intake of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) fatty acids daily for 8 weeks is associated with less impulsive behavior in children with ADHD. Dietary supplementation with omega-3 fatty acids reduces ADHD symptoms in both individuals with ADHD and typically developing children. A Mediterranean diet may improve BIS results, although our results are not conclusive in this population. The daily intake of calories and nutrients in patients taking methylphenidate is generally lower than in a healthy population of similar age. Co-supplementation of vitamin D and magnesium over 8 weeks may improve behavioral function and mental health in children with ADHD.
Are subtitles useful for language learners?
Authors: To Calum
Published: April 2024

Despite the seemingly commonsensical view that captions or subtitles aid comprehension, empirical research is less certain about their recommendation for all language learners. This review article introduces some of the theoretical foundations of multimedia learning before examining recent studies investigating the facilitative effect of L2 captions, L1 subtitles and dual-language subtitles. Qualitative insights from research are then presented, with implications for both research and teaching practice further discussed.  The article concludes by underlining the importance of learner perspectives due to the complexity of factors affecting the pedagogical value of captions and subtitles.

Background: COVID-19 infection has shown to be a multi-system disease and kidneys are commonly affected. AKI is the main risk factor for mortality in COVID-19 infection. There is limited data on Covid-19 infection and kidney involvement among the Nepalese population. Hence this study aims to describe the prevalence, risk factors, and outcomes in the setting of Covid-19 infection and acute kidney injury.
Methods: This was a hospital-based cross-sectional study conducted at the National Academy of Medical Sciences (NAMS), Bir Hospital, Kathmandu, Nepal from January 2021 to June 2021. Ethical approval was obtained from the Institutional Review Board, NAMS (Reference number: 452/2077/78) Convenience sampling method was used. Data obtained was entered in MS Excel 2010 and statistical analysis was done by SPSS version 21. 
Results: Out of 101 patients, 73(72%) were male and 28(28%) were female. The mean age of the total study participants was 51.50 years. The prevalence of AKI among patients with COVID-19 in the ICU and ward of Bir Hospital was found to be 13.9%. A statistically significant association between liver disease and AKI with p-value of 0.018 was observed. The majority of death i.e., 57.14% was for KDIGO stage 3 patients. 3(100%) patients requiring renal replacement observed mortality.
Conclusions: CLD, higher KDIGO staging of AKI, and the need for renal replacement therapy have been associated with mortality in patients with COVID-19 infections.

Published: April 2024

Background: Intraoral periapical radiographs are reported to show the incisive foramen as a typical anatomical landmark. In order to assess the visibility of the incisive foramen in the bisecting angle and paralleling angle approaches, as well as how visible it is in routine periapical radiographs, the current study was conducted.
Methods: This descriptive cross-sectional study evaluated 90 intraoral periapical radiographs of maxillary central incisors. These were scored for visibility of incisive foramen by a radiographic expert using two intraoral radiographic techniques. The data was entered in Microsoft Office Excel sheet 2007 and calculated using SPSS version 20.
Results: In both the paralleling and bisecting radiographs, the incisive foramen could be seen in a total of 63.8% and 36.2% of the images, respectively.
Conclusions: The dentist must have a thorough awareness of how the incisive foramen appears on standard intraoral radiographs. Our research demonstrates that when compared to the bisecting angle technique, the paralleling technique delivers superior visibility of the incisive foramen. Therefore, it is recommended to use the paralleling technique approach to see the foramen.

Published: April 2024

Background: Wrong-way driving, sometimes referred to as ‘one-way’ driving, is a common offence, however, the role mental illness plays is unknown. This study aims to determine the socio-demographic and clinical profile, in addition to the prevalence of mental disorders, among arrested wrong-way traffic offenders in the Benin metropolis.

Methods: Socio-demographic and clinical correlate data was obtained from the records of 18 one-way traffic offenders who were referred to the Federal Neuropsychiatric Hospital, Benin City, Nigeria for evaluation within the last 24 months.

Results: All offenders were males, with an age range of 23-63 years. None of the traffic offenders had a past psychiatric disorder, neither was there any significant finding in their mental state examination. Only three of the offenders tested positive for cannabinoids in a urine toxicology screen.

Conclusion: Mental illness did not contribute remarkably to traffic offending in the sample of offenders sent for psychiatric evaluation. Rather than refer, appropriate punishment should be meted out on offenders to serve as deterrence.

BUDDHIST SOUVENIRS: TYPOLOGIZATION EXPERIENCE
Authors: Элькан О.Б. , Дзембак Н.М.
Published: April 2024

В процессе исследования сформирована типология известных на сегодня буддийских сувениров. Авторы статьи называют ее базовой, поскольку выделяемые в ее рамках категории сувениров могут использоваться не только самостоятельно, но и в разных вариантах сочетаний. В целом, «сувенирная» традиция в буддийской культуре непосредственно связана с традицией гораздо более древней и фундаментальной, охватываемой понятийным полем санскритской категории «дана» («дар», «дарение», «щедрость»). Актуальность проведенного исследования обусловлена необходимостью теоретической разработки вопросов производства, продажи, маркетинга сувенирной продукции в контексте развития туристической сферы как составляющей экономики и культуры в «буддийских регионах» Российской Федерации.

In the course of research, a typology of Buddhist souvenirs known today was formed. The authors of the article call it basic, since the categories of souvenirs highlighted within it can be used not only individually, but also in different combinations. In general, the “souvenir” tradition in Buddhist culture is directly related to a much older and fundamental tradition, covered by the conceptual field of the Sanskrit category “dana” (“gift”, “donation”, “generosity”). The relevance of the study is conditioned by the need for theoretical development of issues of production, sale, and marketing of souvenirs in the context of the development of the tourism sector as a component of the economy and culture in the “Buddhist regions” of the Russian Federation.

Authors:   M.Tech Student, Department of Computer Science and Engineering, Oriental University, Indore, MP India, Sharma Ravi
Published: April 2024

Customer churn poses a significant challenge for companies in the telecom industry, impacting revenue and profitability. In this paper, we present a comprehensive survey of customer churn analysis methodologies, focusing on the application of logistic regression, Kaplan-Meier survival analysis, and the Cox Proportional Hazards Model. Logistic regression serves as a fundamental technique for binary classification, enabling the prediction of churn based on customer attributes and behaviors. Kaplan-Meier survival analysis offers insights into customer survival probabilities over time, facilitating the identification of high-risk cohorts. Additionally, the Cox Proportional Hazards Model provides a flexible framework for analyzing the impact of predictor variables on churn timing, accounting for censoring and time-varying covariates. Through a review of existing literature, case studies, and practical applications, we explore the strengths and limitations of these methodologies in customer churn prediction. We also discuss challenges in data collection, feature engineering, and model evaluation, along with future research directions to enhance churn analysis effectiveness. By leveraging logistic regression with Kaplan-Meier and the Cox model, telecom companies can develop robust churn prediction models to improve customer retention strategies and mitigate revenue loss. Keywords: Customer churn analysis, Telecom industry, Logistic regression, Kaplan-Meier survival analysis, Cox Proportional Hazards Model, Retention strategies.

Authors:   Department of Clinical & Chemical Pathology, Faculty of Medicine, Ain Shams University, Cairo, Egypt., Habib Christine
Published: April 2024

Multiple sclerosis (MS) is a multifactorial polygenic disease; results from autoimmune and neurodegenerative processes which lead to multifocal lesions of the central nervous system. Axonal degeneration was found to be prominent in the inflammation period of MS and contribute to the progression of disability. Soluble N-ethylmaleimide sensitive factor attachment receptor (SNARE) complex plays a vital role in the release of neurotransmitter by synaptic vesicle fusion. Stx-1A protein (Stx-1A), a major component of the SNARE complex, is widely expressed in brain tissue. This study intended to evaluate the prevalence of the Stx-1A gene polymorphism (rs1569061) in the Egyptian population with MS and to investigate its association with various clinical factors. This study included 65 adult Egyptian MS patients and 35 age- and sex-matched normal control subjects. Diagnosis of MS was made by an experienced neurologist according to revised McDonald criteria. All Patients underwent full history taking, included Age of onset of MS, disease duration, disease course and degree of disability according to the Expanded Disability Status Scale (EDSS) and family history of neurological diseases. Stx-1A gene polymorphism (rs1569061) genotyping was performed by TaqMan assay based quantitative real time (qPCR) and verified by sanger sequencer. Genotype and allele frequencies of (rs1569061) did not differ significantly between case and control groups. No difference was detected when comparing the genotype frequency and the allele frequency to different disease parameters. Discrepancy of the minor allele frequency (MAF) of Stx-1A gene (rs1569061) between different populations was noted. In conclusion, our study in Stx-1A gene polymorphism (rs1569061) and MS showed that no difference between the patient and control as regards gene frequency and allele frequency. Predicting no association between the studied polymorphism and MS in the Egyptian population. However, discrepancy between different population was noted as regards the MAF for Stx-1A gene (rs1569061).

Veterinary medications, particularly antibiotics, are crucial elements in the manufacturing of animal feed. Typically, antibiotics are mostly employed in animals for the purpose of treating and preventing infections, as well as promoting growth. The utilization of antibiotics in animals can lead to the presence of antibiotic residues in food products, including milk, eggs, and meat. It is possible for these residues to cause a lot of bad things, like the spread of bacteria that are resistant to antibiotics to humans, immune system problems, allergies, and even cancer (with sulphamethazine, and other drugs). The most harmful consequence of residual drugs is the transfer of resistant antibiotic germs to individuals, aided by the mobility traits of resistance. Controlling the consumption of antibiotics in cattle is imperative in order to mitigate these detrimental effects. The issue should be communicated to individuals and local protocols through formal education. This review will discuss the use of antibiotics in food products and their effects on the health of people.

Published: April 2024

Cyclic volatile methylsiloxanes (cVMSs) are synthesis chemicals used widely in consumer products such as building materials, households, electrical and medical devices, and personal care products. Due to being used in many applications, cVMSs are released into various micro-environments. Recently, the pollution level of cVMSs in the environment including sewage sludge has been gradually concerned. In this work, four typical cVMSs: hexamethylcyclotrisiloxane (D3), octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), and dodecamethylhexasiloxane (D6) were measured in 20 sludge samples collected from a sewage river (To Lich River) in Ha Noi metropolitan by using the gas chromatography-tandem mass spectrometry (GC-MS) method. The method detection limits (MDLs) and the method qualification limits (MQLs) of cVMSs in sewage sludge were a range of (1.20-3.00) ng/g-dw (dry weight) and (3.60-9.00) ng/g-dw, respectively. Recoveries of the surrogate compound (tetrakis-(trimethyl siloxane)-silane: M4Q) in blank and real samples were from (89.4 to 112) % (RSD: 9.2 %). The total concentrations of cVMSs in sewage sludge samples from To Lich River ranged from (260 to 13,800) ng/g-dw. Among the studied cVMSs, D5 was found at the highest levels in a range of (150-6,040) ng/g-dw. To our knowledge, this is the first report on the occurrence of cVMSs in sewage sludge samples in Ha Noi as well as Vietnam. The results indicate that the distribution of cVMSs in environments is significantly high and further studies should be conducted.

Review on Investigating Soil Stabilized Mud Blocks with Combined C&D Waste
Authors: Ganie Umer Nazir , dar Tanzeer Ahmad
Published: April 2024

Buildings built by ancient civilizations like the Mesopotamians and Egyptians were made of clay and other materials, and the use of stabilized soil for construction dates to those times. On the other hand, the scientific underpinnings of soil stabilization were not established until the early 1900s. In comparison to conventional building materials, the use of stabilized soil-based construction materials, such as soil stabilized mud blocks, can offer several advantages, such as improved strength and durability, less of an adverse effect on the environment, and lower costs. The world is facing an issue that calls for the disposal of inorganic solid waste to be addressed right away. This solid waste that is produced when old buildings are demolished is frequently classified as industrial waste or C&D waste. In India alone, enormous amounts of waste are produced, very little of which is recycled. When modifying the properties of stabilized soil, this C&D waste can be used in place of soil or quarry sand. This work explores the use of a stabilizing agent in conjunction with combined C&D waste for soil sampling. The studies use combined C&D waste and soil stabilized mud blocks to test the hollow blocks' water absorption capacity and strength for various replacements. The materials needed for the study came from nearby structures that had been demolished. Using mortar, cylindrical samples for 32 different ratios of mixed construction and demolition waste with a 9% cement content were cast for various compositions. To determine whether the stabilized samples were suitable for use in construction, tests were conducted on their compressive strength and water absorption properties. Based on the least compressive values found in cylindrical samples, the C&D waste was used in ratios ranging from 0% to 100% in place of soil. Mud blocks stabilized by soil were poured and examined for durability, strength, and mechanical qualities. In this study, an effort was made to use C&D waste—that is, brick and concrete waste—in varying amounts to create cylindrical samples that could be used to create concrete and stabilized mud blocks. In order to create cylindrical samples, different ratios of brick waste, concrete waste, and brick-concrete waste were used for 23 mix proportions. Cylindrical samples were manufactured using a cement content of 9 and 12%. These samples' mechanical and physical characteristics, such as their compressive strength, water absorption capacity, and initial rate of absorption, were investigated.

Palestinian diplomacy and communication in latin america case Brazil
Authors: Alzoubi Ahmad Sad
Published: April 2024

Diplomacy and soft power relations with worldwide countries have been and continue to be ambitious for an official Palestinian institution. Political and diplomatic outreach, media communication, and opening relations and embassies with countries and regimes increase legitimacy and convey the message to decision-makers. In Latin America, before the digital connectivity boom, letters and speeches helped build public opinion in favor of the recognition of the Palestinian State. Today, Palestinians are increasingly seeking diplomatic and media communication with the international community to gain support for their full sovereignty, the end of apartheid, settlements, and the recovery of rights. Along with institutional relations, new technologies—although under the control of large corporations—have been exploited by Palestinians to break the siege and allow communication as an extension of diplomatic efforts. This article intends to highlight the role of Palestinian diplomatic relations and media communication between them and the Brazilian government, aiming for political recognition of Palestine. To this end, the research adopts two methodological procedures: literature review and content analysis, based on in-depth interviews. Seven people who worked in the Palestinian diplomatic corps in Brazil were interviewed, including ambassadors and media figures who contributed to diplomatic communication and appeared in the Brazilian media to gain recognition.

No Brasil, o Conselho Nacional de Segurança Alimentar e Nutricional (CONSEA) criado em 11993, é um importante agente para a efetivação do Direito Humano à Alimentação Adequada. O CONSEA é um órgão de assessoramento do Presidente da República composto por representantes da sociedade civil e representante do governo, que visa propor ações governamentais, medidas e diretrizes no campo da Segurança Alimentar e Nutricional (SAN) no país. No entanto, desde sua origem, o CONSEA foi extinto duas vezes, em 1995, retornando em 2003, e em 2019, retornando em 2023. O recente retorno veio concomitante a um grave cenário de insegurança alimentar no Brasil, que reforça a necessidade emergencial do combate à fome no país. Diante do exposto, a presente pesquisa teve como objetivo analisar o primeiro ano de retorno do CONSEA e as perspectivas para a Segurança Alimentar e Nutricional no Brasil para 2024, a partir do que foi estabelecido na 6ª Conferência Nacional de Segurança Alimentar e Nutricional. Nesse sentido, buscou-se entender, como ocorreu a criação do CONSEA, como o órgão funciona e é estruturado e quais foram as discussões e propostas trazidas pelo conselho em 2023. O estudo foi realizado a partir da pesquisa bibliográfica qualitativa e exploratória, com base, na plataforma do governo federal, jornais virtuais e em periódicos acadêmicos que abordam o CONSEA e o tema da Segurança Alimentar e Nutricional. A partir do estudo, observamos que o CONSEA voltou engajado em retirar o Brasil do Mapa da Fome da ONU até 2030, através do Programa Brasil Sem Fome. Além disso, o conselho vem buscando enfrentar essa luta a começar por seus determinantes estruturais, fortalecendo o Sistema Nacional de Segurança Alimentar e Nutricional e sempre norteado pela participação da sociedade civil. Por fim, fica evidente a importância da constante luta para fortalecer progressivamente órgãos indispensáveis como o CONSEA e resistir às frequentes tentativas de aniquilar os avanços sociais já conquistados.

A Tuberculose (TB) persiste enquanto desafio às políticas de saúde pública no Brasil, com índices que despontam em posição de destaque em relação à prevalência da doença no contexto global. O presente artigo tem por objetivo descrever o perfil epidemiológico do abandono do tratamento de TB no estado da Paraíba, entre os anos de 2013 e 2022. Trata-se de um estudo ecológico, retrospectivo, de natureza descritiva com abordagem quantitativa, desenvolvido a partir de dados secundários obtidos do Sistema de Informação de Agravos de Notificação (SINAN). Foram registrados 1.794 casos de abandono de tratamento da tuberculose no estado da Paraíba. Os resultados evidenciaram regressão dos casos no período inicial avaliado, impulsionada pelo surgimento de iniciativas nacionais, contrastando-se com aumento progressivo durante o período da pandemia por Covid-19, o qual foi responsável por gerar novos obstáculos ao controle da doença. Além disso, observou-se notória predominância de casos na população masculina de jovens adultos entre 20 e 39 anos, de cor/raça parda e preta e que cursaram parcialmente o Ensino Fundamental, residentes na macrorregião de saúde de João Pessoa, como manifestação das desigualdades no acesso aos serviços de atenção primária em saúde. Diante desse quadro, faz-se urgente a elaboração de estratégias integradas de enfrentamento e incentivo à adesão medicamentosa no tratamento da TB, de modo a barrar a perpetuação dessa problemática no cenário nacional.

The aim of the study was to analyze the effectiveness of aerobic training (AT) with restricted blood flow (BFR+AT) and ischemic preconditioning (PCI+AT) on the anaerobic performance of non-exercising individuals. This is a longitudinal study, with a sample of 23 sedentary men (age= 30.0 ± 5.57 years; = 1.77 ± 0.07 m; body mass= 91.10 ± 18.66 kg), who underwent specific aerobic power tests in vertical cycloergometer, step and treadmill. An aerobic training program was carried out for 4 weeks. The subjects were randomized into three groups: BFR+AT: continuous at 50% of the auscultatory pulse; PCI+AT: three cycles of 05' min of vascular occlusion/reperfusion at 220 mmHg; Control: AT without BFR. All groups performed the same training (6' min per ergometer with 45" min interval at an intensity of 50% of VO2max). Anaerobic performance was verified using the RAST TEST, analyzing the measurements of lactate (La), peak power (PP) and fatigue index (%F). There were significant differences in La Pre vs Post levels (∆ =40%) in the PCI group; an increase was noted in PP (∆=23%) compared to the other groups; there was no significant difference in any of the groups in the F variable. However, there was a greater tendency to fatigue in the Control group (∆=23%). Aerobic training with restricted blood flow and ischemic preconditioning has been shown to be effective in improving anaerobic performance, considering lactate levels, peak power. However, the fatigue index showed a greater tendency of decreasing fatigue, thus improving the anaerobic capacity of individuals without regular physical practice.
