Analysis of the distribution of Muscardinus avellanarius (Rodentia) in Ukraine using the MaxEnt model
Authors:   Taras Shevchenko National University of Kyiv (Kyiv, Ukraine), Novoseltseva Yuliia
Published: August 2024

In this study, the current state of hazel dormouse (Muscardinus avellanarius) populations in Ukraine was analysed in detail using the MaxEnt geographic modelling tool. It is known that fragmentation of natural ecosystems is one of the main threats to biodiversity conservation. Species with low population numbers, such as the hazel dormouse, are particularly vulnerable to this process. Reducing the area of forests leads to a reduction in the number of areas available for nesting, makes it more difficult to find food and can change the microclimate in forest fragments, which leads to changes in the vegetation cover on which the food base depends. The isolation of individual populations limits the opportunities for genetic exchange and adaptation to changing environmental conditions. To estimate the potential range, we developed a distribution model using data on records of the species and climatic characteristics of these areas. The results of the modelling allowed us to identify areas where there is a high probability of occurrence of this species and to identify key factors affecting its distribution. The model allowed us to identify areas where there is a high probability of occurrence of this species, even in the absence of direct observations. It is an important tool for planning measures to protect and restore natural habitats. The analysis of the obtained data showed that the distribution of the hazel dormouse is most influenced by climatic factors that reflect the temperature of the warmest months, humidity, and precipitation. It is these factors that we recommend to be used to develop more accurate distribution models of the species and predict the potential consequences of climate change for its range. The study highlights the importance of preserving forest ecosystems to maintain biodiversity in general and its index species, such as the hazel dormouse. The obtained results can be used to develop effective strategies for the conservation of the hazel dormouse and other species that depend on forest habitats, including the creation of new nature reserves, reforestation and preservation of old forests.

Authors: Ponchirolli Osmar , Behrens Marilda Aparecida
Published: August 2024

This article aims to analyze the relevance of presenting and reflecting on innovative practice in teacher training from the perspective of complex thinking. We chose the studies of Edgar Morin, who formulates the complexity epistemology. The research problem was: how can Edgar Morin's epistemology of complexity, which embraces the reform of thought and the reconnection of knowledge, support innovative practice in teacher training? The research methodology was qualitative, of the action-research type, which is justified because the author carried out an intervention with teachers, through a three-year experience at a higher education institution in Curitiba, Paraná. The research findings highlighted the importance of including the founding elements of the complexity epistemology in the Institutional Pedagogical Project and in the Pedagogical Projects of the Courses, to bring about a real paradigm shift in teacher training.

Authors: Lutinski Junir Antônio
Published: August 2024

Mosquito-borne arboviruses represent one of the main challenges for public health today. The Aedes genus includes more than 950 mosquito species, many of which cause discomfort through their bites and are disease vectors. However, little is known about this biodiversity and its role in the context of public health. This study aimed to list the worldwide diversity of mosquitoes belonging to the Aedes genus with the potential to transmit pathogens to humans. An integrative literature review was conducted. The articles were searched during July 2024, in the following databases: Lilacs, Scielo, Science Direct and PubMed. A total of 38 species of mosquitoes belonging to the Aedes genus with the potential to transmit pathogens to humans were listed. The literature consulted reports a total of 44 pathogens potentially transmitted by Aedes mosquitoes, including Dengue, Zika virus, Chikungunya, yellow fever, Rift Valley fever virus, West Nile virus, Ross River virus, Japanese encephalitis virus, Saint Louis encephalitis virus, and equine encephalitis virus. This study provides useful information to support further research and the development of actions to monitor and control mosquito species with vector potential.

Published: August 2024

Different generations have different characteristics. The Baby Boomers Generation presents linear reasoning, following all stages of learning. Generation X adapts easily to technology. Generation Z, born in the late 90s and early 2000s, is the first to be born in a mostly digital and connected era. The Alpha Generation, made up of children born since 2010, was also born in the digital era, but their relationship with technology is much greater, as its use is intuitive. This bibliographical study aims to highlight the profile of the Alpha generation, its characteristics and its conduct towards the educational process, as well as the teaching and learning process of this new generation, which is characterized by immersion in digital technologies, investigating the emotional and social presence in it. The study shows that school spaces, public and private, must invest in technological resources and specialized professionals to promote quality education through digital media, as it will be imperative that new generations, from Alpha onwards, will be increasingly immersed in the context of digital technology.

Authors: De Jesus Severo Rubinaldo , Vasconcelos Moreira Cleilton , Dos Santos Oliveira Michelle , Dos Santos Almeida Gleicia
Published: August 2024

Salinity makes it difficult for seeds and roots to absorb water, which can affect the germination and initial growth of seedlings. Therefore, the objective of the present work was to evaluate the effect of different concentrations of calcium chloride (CaCl2) and potassium chloride (KCl) according to the combination of each treatment (T1: 0 g CaCl2 + 0 g KCl, T2: 0 g CaCl2 + 2.44g KCl, T3: 7.98g CaCl2 + 0g KCl, T4: 7.98g CaCl2 + 2.44g KCl, T5: 19.95g Cacl2 + 0g KCl, T6: 19.95g CaCl2 + 2.44g KCl), in the germination of yellow passion fruit seeds. The parameters of Germination Speed Index (IVG), First Germination Count (PCG) and Germination Percentage (G) were analyzed, and the variables: shoot length (CPA), leaf number (NF), leaf length root (CR). The results indicated that increased salinity significantly reduced seed germination, with deleterious effects at higher salt concentrations.

Published: August 2024

This manuscript presents the evaluation of relevant geotechnical properties of the soil profile in the northern region of Campinas, which are important for geotechnical engineering practice and development in São Paulo State. Disturbed and undisturbed samples from the subsoil were collected through the excavation of inspection shafts at the experimental site for Soil Mechanics and Foundations research at the State University of Campinas, located at the Faculty of Civil Engineering, Architecture and Urbanism (FEC). Laboratory tests were conducted, including soil characterization, soil shear strength, soil compressibility, soil permeability, and soil suction tests. The characterization tests indicated that the upper soil layer is subject to surface effects and more direct weathering action, with noticeable variations in the liquid and plasticity limit values. The permeability test results showed no significant variation between the values obtained in the vertical and horizontal directions. The soil-water characteristic curves for the studied profile were bimodal, typical of tropical soils with macro and microaggregated structures.

Published: August 2024

The effects of the COVID-19 pandemic permeate various spheres of society. In Brazil, marginalized populations who face chronic difficulties accessing minimum human and social rights have been most impacted. In Rio de Janeiro, socio-spatial inequality influenced the spread of infection in some areas to the detriment of others, laying bare social disparities. Descriptive analyses, calculations, and logistic regression were conducted to assess the tested variables associated with a higher likelihood of COVID-19 hospitalization from January 2020 to January 2021 in Rio de Janeiro. There was a profile of individuals more vulnerable to COVID-19 infection and variables demonstrating associations with worse outcomes. A historical and social context is associated with COVID-19 cases and complications and repercussions.

Published: August 2024

Public policy is the concepts and principles that form the lines and basis of plans in carrying out work, leadership, and ways of acting (regarding orders, organizations, and so on). This policy can be implemented in government, the private sector and organizations. Policy is one of the things that is considered to be used in realizing a result from an action. The term implementation is usually associated with an activity carried out to achieve certain goals. One effort to realize this in a system is implementation. According to the law of the Republic of Indonesia Republic of Indonesia no. 25 of 2004 explains that a program is a way to implement policies that contain one or more activities carried out by the government/institution to achieve targets and objectives. Cpondoh District, Tangerang City created a program as a public policy for the community. However, there is still a problem with this program, namely that the community still does not want to participate and is still embarrassed if their children are categorized as approaching stunting, even though in Cipondoh District itself there are still children who experience stunting prevention. This research aims to determine the implementation of the Mutual Cooperation Program to Prevent Stunting (GOCENG) policy and determine the inhibiting factors and efforts made. This type of research is qualitative with a descriptive method that uses the results of analysis from Donald S. Van Meter and Carl E. Van Horn (1975) using 6 indicators, namely:

Policy standards and targets 2. Resources 3. Characteristics of the implementing organization 4. Communication between related organizations and implementation activities 5. Disposition 6. Social, economic and political environment. The results of this analysis show that the Mutual Cooperation Program to Prevent Stunting (GOCENG) in Cipondoh District has not been successful because there are still obstacles.

Published: August 2024

Introdução: A COVID-19 é uma doença de acometimento respiratório com alta capacidade de disseminação. Sua prevenção consiste em respeitar o distanciamento social, usar máscara e realizar a higienização adequada de mãos e superfícies, o que resultou em um aumento na quantidade de resíduos sólidos domiciliares gerados durante o período de isolamento social. O objetivo deste estudo é identificar o conhecimento de residentes de XXX sobre o manejo de resíduos contaminados ou potencialmente contaminados por SARS-CoV-2. Métodos: Consiste em uma pesquisa exploratória-descritiva de abordagem quantitativa Resultados: De maio a julho de 2021, entrevistamos 420 participantes, com 30,7% sendo do sexo masculino (129) e 69,3% do sexo feminino (291). A maioria (40%) estava na faixa etária de 20-24 anos, seguida por 25-29 anos (11,2%) e 40-44 anos (10,2%). Quanto ao conhecimento da Política Nacional de Coleta de Resíduos Sólidos, 228 participantes (54,3%) desconheciam-na, enquanto 192 (45,7%) a conheciam. Em relação ao 'Protocolo para procedimentos especiais na gestão de resíduos sólidos urbanos em XXX, para a prevenção do coronavírus', 310 participantes (73,8%) não tinham conhecimento, enquanto 110 (26,2%) estavam cientes de sua existência. Discussão: Foi constatado que o desconhecimento da população acerca das medidas contidas no protocolo municipal para a prevenção da contaminação pelo coronavírus resulta em um descarte inadequado de máscaras, luvas, lenços e guardanapos, mesmo os usados de forma preventiva, e armazenamento incorreto dos resíduos de casos suspeitos ou confirmados de COVID-19, o que eleva o risco de contaminação tanto para a população como para os servidores públicos na limpeza pública.  Conclusão: O desconhecimento da população sobre o protocolo de prevenção do coronavírus resulta em descarte inadequado de materiais e riscos de contaminação. Ainda, a falta de conhecimento dificulta a implementação e fiscalização do protocolo, especialmente para aqueles sem acesso à internet.

Authors: Rocha Arthur , Milan Eveline Pipolo , Caminha Renan Oliveira de Carvalho , Paiva Daniel Felipe Fernandes
Published: August 2024

Objectives: With the advancement of the pandemic and better knowledge of coronavirus disease 2019 (COVID-19), new ways of tackling this disease have come to light. Therefore, we propose this systematic review to better understand the action of vaccines in combating mortality caused by this virus, especially in transplant patients. Methods: In this systematic review with meta-analysis, the reviewers analyzed 389 eligible articles according to the criteria used and blindly selected the studies that provided data on transplant patients and mortality, resulting in 15 works included in the study. The screening results were added to a spreadsheet, and data was compiled. Results: Of the 15 articles included, it was possible to observe a significant drop in the overall mortality rates of vaccinated patients, except in studies that used the inactivated virus immunizer. Furthermore, the mortality of infected patients, even after vaccination, remained close to that of the unvaccinated group, as did the need for mechanical ventilation. Conclusion: Immunization of transplant patients can significantly reduce mortality rates for this portion of the population. However, as they have a reduced seroconversion rate, different ways of achieving an adequate immune response must be considered

Authors: Klein Francine Flores , Beuren Amanda Guterres , Oliveira Vitor Pelegrim de , Mello Renato Gorga Bandeira de
Published: August 2024

Objective: To investigate the association between diet quality, nutritional status, and sarcopenia in a sample of the oldest old. Methods: Using a cross-sectional design, individuals aged ≥ 80 years were enrolled. To determine their energy and macronutrient intake, 24-hour dietary recall was used to calculate the Healthy Eating Index. Nutritional status was categorized based on Mini Nutritional Assessment (MNA) scores. Sarcopenia was diagnosed using both the 2010 and 2018 EWGSOP criteria. Electrical bioimpedance was used to calculate the muscle mass index. Muscle strength was measured through handgrip dynamometry, and muscle performance was determined with a 4-m gait speed test. To test the association between the HEI with sarcopenia, means of HEI scores were compared between sarcopenic and non-sarcopenic participants using indendent t-tests. Prevalence rate ratios were calculated using a Poisson Regression model with robust estimation of standard errors. Results: The study population consisted of 119 participants, predominantly women (n = 67; 56.3%), with a mean age of 83.4 (SD, 3.0) years. The prevalence of sarcopenia varied significantly according to the classification criteria, being higher according to EWGSOP 2010 than EWGSOP 2018 criteria (46.7 vs. 17.6%), as expected. Female participants and those categorized as malnourished presented higher prevalence of sarcopenia. Nutrition quality, estimated by the Healthy Eating Index, was not associated with the outcome. Reduced total energy and high protein intake were independently associated with both sarcopenia and severe sarcopenia, regardless of the diagnostic criteria. Conclusions: The Health Eating Index was not associated with sarcopenia in this sample of older adults ≥80 years. Sarcopenia prevalence, as defined by the EWGSOP 2018 criteria, was higher in those with MNA≤24 and with reduced daily total energy comsumption independently of age, sex and education attainment. Higher protein intake, oposed to expected, was indenpendently associated with sarcopenia, possibly due to protopathic bias. Large longitudinal studies are still required to investigate the relationship between nutrition quality and Sarcopenia in 80+ aged adults.
Anxiety-inducing factors among educators in the Capricorn district of Limpopo, South Africa
Authors: Maaga Khomotso , Mokwena Kebogile
Published: August 2024

This study was aimed at screening for anxiety symptoms among educators in the Capricorn District of Limpopo Province, South Africa. Recent literature has identified the school environment as a risk factor for anxiety, putting teachers at a higher risk. We collected data from 381 teachers using a quantitative cross-sectional study design. The Generalized Anxiety Disorder (GAD-7) scale, along with a researcher-developed socio-demographic questionnaire, was used to determine the prevalence and associated risk factors for anxiety symptoms. Stata-14 was used to analyze the data through the use of bivariate and multivariate analysis. The sample consisted largely of black (n=318, 83.46%), female (n=270, 70.87%) teachers from 25 schools. The prevalence of anxiety was 36.85%, with a majority falling under the mild category (n=85, 22.31%). Personal factors such as gender, race, home language, whether the participant had sought professional mental health assistance in the past 6 months, and the impact of COVID-19 were significantly (p=0.05) associated with the symptoms of anxiety. Additionally, workplace factors such as school of employment and subjects taught were also significantly associated with anxiety symptoms. There is a high prevalence of anxiety symptoms among educators, which may negatively affect the students under their care.
PLCBlox: Using blockchain-based audit trails to generate secure PLC commands
Authors: Short Andrew R , Orfanoudakis Τheofanis G , Leligou Helen C
Published: August 2024

This research paper discusses security issues with current deployments of Programmable Logic Controllers (PLCs) and Supervisory Control and Data Acquisition Systems (SCADA) in the industry and proposes a solution that enables PLC devices to query a blockchain infrastructure for commands and setpoints. The blockchain assumes a dual role in this context: serving as an immutable audit trail database as well as a trusted source for critical commands and setpoints. In contrast to the conventional paradigm, this novel approach does not require write access at the PLC level, thus minimizes its attack surface and helping to protect against known and zero-day vulnerabilities often used in cyberwarfare, such as in the case of the notorious Stuxnet worm. Applications that enforce the logging of user operations for Good Manufacturing Practices (GMP) or compliance purposes use the blockchain network as an audit trail database for user actions. Any attempt to maliciously circumvent the logging operation would not affect the operation of a critical process. Additionally, a prototype implementation developed as part of this research finds that modern PLC devices are more than capable of interacting with private Ethereum blockchain nodes. The required libraries and user code consume a small percentage of available resources, while the duration of a complete request-response cycle measured around 22msec. The authors anticipate that PLCBlox can be used as a drop-in replacement for applications requiring higher security standards and logging enforcement, such as nuclear power plants or other critical infrastructure.

Authors: Thuy Duyen Dang Thi , Thu Huyen Giang Thi
Published: August 2024

This paper investigates the long-term relationship between factors affecting people's livelihoods after tourism investment in the tourism sub-region south of the Red River in Vietnam. The study used survey data and multiple linear regression econometric models from the three provinces of Ninh Binh, Nam Dinh and Thai Binh in the South Red River tourism sub-region from February 2023 to August 2023. Research results show that all eight factors are statistically significant and impact people's livelihoods. These seven factors have a positive impact while one factor harms their livelihoods. The three factors that have the most positive impact on livelihoods are (1) employment in the tourist destination, (2) local government policies and (3) agricultural land quality. The remaining factors such as (4) social culture, (5) infrastructure, (6) jobs outside tourist destinations and (7) social welfare have the same impact but less impact. Meanwhile, the factor that harms their livelihoods is the amount of agricultural land. In addition, employers in the tourism destination and local government policies continue to have an important impact on the livelihoods of the local population to assess the sustainability of the impact factors while less impact variables are excluded. The research results are the basis for proposing recommendations to diversify people's livelihoods after tourism develops in the southern Red River tourism sub-region.

This empirical support confirms the success of the integrated model in advancing statistical competence and collaborative skills, especially in the context of teacher education. The positive impact on statistical knowledge and collaborative abilities highlights its potential to shape future pedagogical practices, underscoring the significance of this innovative approach in enhancing the skillset of preservice teachers.
Information technology-based environmental management: A review
Authors: Valdez Rogelio Estalin Ureta , Orozco Ángel Patricio Flores , Pérez Luis Patricio Tierra , Zambrano Patricio Vladimir Méndez
Published: August 2024

This study aimed to describe the role of information and communication technologies (ICT) in the management of natural resources. We conducted a systematic review of 320 articles from academic databases like Scopus, Latindex, Scielo, Dialnet, Redalyc, and Google, scanning the period from 2018 to 2023. We selected forty articles that discussed the application of ICT in predicting and mitigating issues related to climate change, erosion, environmental pollution, drought, and floods. The results indicated that climate change is one of the main drivers of environmental problems such as droughts and floods. Therefore, we concentrated our efforts on developing technologies like artificial intelligence (AI), machine learning (ML), the use of sensors, the Internet, and others. These tools make it possible to manage large amounts of information in real time and make informed decisions to prevent the aforementioned environmental problems. Despite the success of new technologies, it is important to note that they are not within the reach of the entire population due to the existing gap between the most technologically developed countries and those that are lagging. Therefore, we need to make additional efforts to enhance accessibility to technologies, enabling all countries to reap their benefits. In addition, efficient management of natural resources is required to minimize soil and water pollution. This implies the adoption of sustainable practices in the productive sector.

Tribology, as a science that studies friction in mechanisms and their wear, occupies an important place in the combination of education, science  and industry. Therefore, the training of future physics teachers in the field of tribology is one of the urgent issues. The purpose of this study is to increase the effectiveness of teaching in the field of tribology and to evaluate the effectiveness of digital education in forming  the professional competencies of students in this field.  This research also used the methods of modeling in a digital environment, software and constructive design along with the methods of theoretical analysis. In addition, a pedagogical experiment was conducted in which 86 students participated. The learning outcomes were assessed using questionnaires. As a result of the research, an elective course  “Physical Foundations of Tribology”  was developed  and digital resources for the discipline are included in the educational program. The results showed that the students in these programs have a high level of professional creativity and a positive attitude towards creative educational activities. They are also sufficiently prepared to use digital learning materials for this course (M = 3.89). The educational and methodological test showed how well e-learning resources have been developed to help students master the discipline of tribology at a professional level. This is evidenced by the fact that about 75% of students demonstrated a high level of professional knowledge and abilities. The results of the study are recommended to be used at all stages of training future teachers.

Authors: Kouadria Mohamed Abdeldjabbar , Kouadria Selman , Chaib Habib
Published: August 2024

This paper presents a contribution to the control of a Doubly-Fed Induction Generator (DFIG) integrated into a wind turbine using nonlinear control. The parameters involved in this study are the active and reactive powers exchanged between the DFIG stator and the grid. For this purpose, the modeling of the DFIG with the cascaded rectifier-inverter PWM structure was established. A numerical simulation of the DFIG, powered by the cascaded structure and controlled by the developed strategies, was performed. The simulation results show that the sliding mode control (SMC) provides a better transient response , with a shorter response time and reduced overshoot. Furthermore, it maintains good performance and stability in the presence of parameter variations such as resistance and inductance. The proposed control algorithm is also robust against parameter variations and the resulting dynamic response is fast. The simulation results confirm the validity of the mentioned advantages and the effectiveness of the proposed method. The effectiveness and robustness of the control technique were implemented and tested under MATLAB/Simulink environment.
Energy-efficient routing protocol for WSN based on relay node selection and A-star algorithm
Authors: Kaddi Mohammed , Masmoudi Ramadhan , Omari Mohammed
Published: August 2024

Due to miniaturization constraints and manufacturing costs, wireless sensor networks (WSN) sensor nodes are generally outfitted with restricted resources concerning computing capability, energy, data storage capacity, and data delivery rate. These constraints encourage a significant portion of the research issues in WSNs, particularly the energy constraint, which is a fundamental issue. This paper suggests an innovative routing protocol that optimizes energy use called RNS_A-star, which combines a routing algorithm using a relay node and an improved heuristic for the A-star algorithm. The RNS_A-star protocol first applies a data routing algorithm using a relay node, which allows either using a relay node or simply sending the intra-cluster data to the CH. Then, the A-star algorithm is used to construct a multi-hop routing route between the CHs and the base station (BS) in order to find the best path for reducing energy consumption during data transmission. Simulation results show that the suggested RNS_A-star protocol performs better than ECO-BAT, LEACH-IACA, and LEACH protocols regarding energy conservation and extending network lifetime.

Foram produzidos compósitos que utilizam menor concentração de clínquer em substituição de materiais menos poluentes. Por meio de ensaios nas argamassas no estado fresco, foi observado a influência da variação da relação água/cimento e da porcentagem de um aditivo superplastificante em parâmetros como fluidez, consistência, trabalhabilidade e capacidade de extrusão, que são essenciais para avaliar o uso dos compósitos estudados para impressão 3D. Os resultados mostraram que o aumento do superplastificante melhorou a tixotropia da argamassa inicialmente, entretanto, as misturas com maior teor de superplastificante se tornaram rígidas mais rapidamente após 40 minutos.O estudo destaca a importância de ajustar os componentes das misturas para otimizar o desempenho na impressão 3D, promovendo uma construção mais eficiente e sustentável. Além disso, aponta para a necessidade de novos testes para aprimorar a formulação dos compósitos e adequá-los às especificidades dos equipamentos de impressão 3D.

A embolia gordurosa é caracterizada pela obstrução de pequenos vasos sanguíneos por gotículas de gordura, frequentemente associada a fraturas de ossos longos, como o fêmur, ou procedimentos ortopédicos, sendo um assunto de extrema importância nos pacientes vítimas de trauma. Embora a maioria dos casos seja assintomática, a síndrome da embolia gordurosa (SEG) pode ocorrer, apresentando complicações severas. Os sintomas típicos da SEG incluem insuficiência respiratória, alterações neurológicas, como confusão mental e letargia e outros, sendo a SEG uma emergência médica que requer rápida identificação e intervenção para evitar piores desfechos.  Este estudo revisa a fisiopatologia da SEG, dividida em fases mecânica e bioquímica. A fase mecânica envolve a entrada de gordura na circulação, especialmente após fraturas, enquanto a fase bioquímica, ocorrendo nos pulmões, pode desencadear a síndrome do desconforto respiratório agudo (SDRA) devido à lesão endotelial e inflamação alveolar. A compreensão aprofundada dos mecanismos da SEG é crucial para melhorar o manejo clínico desta condição complexa e desafiadora.

Introdução: A leucemia linfocítica aguda (LLA) é uma doença degenerativa causada pela proliferação clonal de células progenitoras linfóides. Objetivo: Observar a correlação da LLA com a Síndrome de Down (SD) e como isso afeta as crianças com SD. Metodologia: Trata-se de uma revisão integrativa de literatura, a procura por artigos foi realizada durante os meses de dezembro de 2022 e fevereiro de 2023, utilizando as bases de dados SciElo, BVS e LILACS. Os descritores em saúde, retirados dos Descritores em Ciências da Saúde (DeCs), foram: Síndrome de Down; Pediatria; Leucemia Linfóide Aguda. Foram definidos os seguintes critérios de inclusão: estudos gratuitos para acesso, sem necessidade de cadastramento prévio, publicados entre 2019 e 2024, escritos em português e inglês. Já como critério de exclusão, foram eliminados estudos repetidos e fora do contexto. Por fim, apenas 11 artigos foram utilizados para compor a amostra final. Resultados e discussão: A ocorrência de LLA em crianças pode ser atribuída a vários fatores de risco. A SD, um distúrbio cromossômico que aumenta substancialmente as chances de desenvolver LLA, é um fator de risco significativo. A investigação indica que as crianças com SD têm uma maior susceptibilidade à leucemia, incluindo LLA, devido aos mecanismos genéticos e biológicos em jogo. Conclusão: Em suma, a observação da leucemia linfoblástica aguda em crianças portadoras de trissomia do cromossomo 21 esclarece a complexa relação entre a predisposição genética e a vulnerabilidade à doença.

Com o aumento do diabetes, a influência genética, especialmente o polimorfismo do gene FTO, é extensivamente estudada em relação a essa condição, considerando também fatores ambientais e comportamentais. Dessa maneira, objetivou-se avaliar a relação entre o gene FTO e a predisposição ao diabetes. O presente estudo compreende uma revisão sistemática da literatura científica abrangendo as seguintes fases: (1) formulação da pergunta de pesquisa; (2) estipulação de objetivos; (3) delineamento dos critérios de inclusão e exclusão; (4) especificação das informações a serem obtidas dos artigos selecionados; (5) avaliação dos resultados; e (6) elaboração de discussão e apresentação dos dados, na qual foram selecionados artigos publicados entre os anos de 2018 a 2023, utilizando bancos de dados como o Pubmed, MEDLINE, LILACS e SciELO, incluindo estudos publicados em língua inglesa e portuguesa. Os objetivos específicos incluem a realização de uma revisão completa da literatura e o desenvolvimento das análises genéticas das variantes do gene FTO na amostra de pacientes. Há um aumento de evidências que apontam para o fato de que a desregulação do gene FTO desempenha um papel na ocorrência de anormalidades no metabolismo da glicose e dos lipídios. Em resumo, o estudo busca aprofundar o conhecimento sobre a conexão entre gene FTO e a diabetes, com o intuito de ajudar a preencher algumas lacunas a respeito do gene e suas variantes.

The shortage of human donors for heart transplants has driven research into viable alternatives, such as heart xenotransplantation. This study conducted a quantitative analysis of the perspectives of heart xenotransplantation in the treatment of patients with heart disease. The objective was to evaluate clinical efficacy, the immunosuppression techniques used, the results obtained in case studies and meta-analyses, and compare xenotransplantation with allogeneic transplantation methods. The methodology involved a literature review covering the period from 2014 to 2024, using databases such as Scielo, Google Scholar, scientific journals, repositories, and virtual libraries. Initially, 105 studies were found, of which 15 were selected after applying inclusion and exclusion criteria. The results showed that grafts from genetically modified pig hearts can survive for extended periods in non-human primates, with some survivals documented for up to 945 days. Effective immunosuppression techniques, such as CD40-CD154 costimulation blockade and the use of anti-CD20 antibodies, significantly reduced episodes of acute rejection. Practical implications include the potential reduction of waiting time for patients in need of transplants and offering new hope for those with terminal heart failure. However, technical, ethical, and biological challenges still need to be overcome. It is concluded that heart xenotransplantation is a promising field that deserves continuous attention and investment in research to advance towards safe and effective clinical application.

O exame colpocitológico, também conhecido como Papanicolau ou preventivo, é recomendado para a identificação precoce de alterações nas células do colo do útero, sendo capaz de reduzir significativamente a morbimortalidade de mulheres por essa patologia. No entanto, apesar desse exame ser a principal estratégia de rastreamento do câncer cervical e estar disponível na rede pública e privada de saúde, estima-se que 12% a 20% das mulheres entre 25 e 64 anos nunca o tenham realizado, o que contribui para a detecção tardia da doença e maior probabilidade de morte. Trata-se de um estudo descritivo do tipo transversal quantitativo, realizado com 30 mulheres com idade de 25 a 64 anos, sendo os dados coletados de janeiro a maio de 2023 por meio da aplicação de um questionário com questões semiestruturadas e uma questão aberta. Os dados obtidos por meio das perguntas fechadas foram dispostos em tabelas e agrupados em quatro categorias pré-estabelecidas: perfil socioeconômico e demográfico; participação em atividade educativa e conhecimento relacionado ao exame colpocitológico; prática na realização de exame colpocitológico; aspectos relacionados ao serviço de saúde. Observou-se que há diversas barreiras que contribuem para a não adesão das mulheres à realização do exame colpocitológico. É de fundamental importância que essas barreiras sejam identificadas a fim de que profissionais e gestores possam efetivar programas e implementar ações que visem a diminuição das desigualdades sociais, integralidade da assistência prestada e maior adesão das mulheres a essa prática.
