Authors: Savadogo Manuel , Hupp Jürgen , Dräger Tobias , Stonis Malte , Nyhuis Peter
Published: February 2025

Eine stetig steigende Anzahl an Produktvarianten, kürzer werdende Produktlebenszyklen, sowie sich immer schneller wandelnde Fabriken erhöhen die Anforderungen an die Intralogistik. Damit einhergehend wird eine immer leistungsfähigere Transportlogistik mit hoher Flexibilität und Skalierbarkeit der eingesetzten Transportsysteme notwendig. In der Praxis können heute bereits Kommunikationsprobleme auftreten, deren Folge negative Auswirkungen auf die zu erwartende Logistikleistung sind. Wird zukünftig die Anzahl an teilnehmenden Fahrerlosen Transportfahrzeugen (FTF) erhöht, ergeben sich darüber hinaus starke Skalierbarkeitsprobleme. Neue Konzepte setzen auf Schwärme von FTF, um die Kommunikation von FTF zu verbessern und dadurch die Logistikleistung zu erhöhen.

Vitamin D reduces VSMC foam cell formation and protect against AS progression
Authors: Zhang Xiaoling , Liu Juxiang , Quan Jinxing , Han Lei , Luo Gaixiang , Jiang Panpan , Jing Jie
Published: February 2025

The role that vascular smooth muscle cell (VSMC)-derived foam cells play as drivers of atherosclerosis has been a growing focus of recent research interest. Toll-like receptor 4 (TLR4) has been identified as a regulator of the formation of VSMC foam cells, while vitamin D can reportedly suppress macrophage-derived foam cell development. Our aim is to investigate Whether vitamin D can similarly suppress the formation of VSMC foam cells, as does the role that TLR4 plays in this pathogenic context.The impact of vitamin D on VSMC-derived foam cell and atherosclerotic plaque formation was assessed, and the expression of cholesterol transport-related genes and TLR4 was assessed in ApoE-/- mice. The impact of 1,25(OH)2D3 on the ox-LDL-mediated formation of foam cells and the underlying molecular mechanisms were also examined in VSMCs cultured in vitro. Supplemental vitamin D administration resulted in a pronounced reduction in aortic atherosclerotic plaque formation and the development of SMA-a-positive foam cells. Vitamin D further suppressed TLR4, CD36, and SR-A in atherosclerotic plaque lesions while promoting ABCA1, ABCG1, and LXR-α upregulation. 1, 25 (OH)2 D3 significantly reduced Dil-ox-LDL uptake and increased NBD-LDL efflux in VSMCs, in addition to suppressing TLR4, CD36, and SR-A expression, while upregulating ABCA1, ABCG1, and LXR-α. Knocking down TLR4 impaired VSMC foam cell formation, while 1,25(OH)2D3-induced JNK activation suppressed TLR4 signaling and promoted VSMC foam cell development. Our study reveals that Vitamin D can reduce VSMC foam cell formation and protect against atherosclerotic progression through the JNK-TLR4 signaling pathway.
Contemporary Nonpharmacological Strategies to Manage Preoperative Anxiety: Nonsystematic Review
Authors: Kuzminskaitė Vilma , Ramaškaitė Agnė , Semenkovaitė Justina , Kontrimavičiūtė Eglė
Published: February 2025

Background: Preoperative anxiety affects the majority of surgical patients and has a huge impact on their well-being and recovery. Pharmacological anxiety treatment does not always result in the desired effect and occasionally causes side effects. To address this issue, recent research is focused on inventing and studying nonpharmacological anxiety management techniques.Objectives: To review the diversity of recent nonpharmacological anxiety-reducing methods for adult and pediatric patients and compare their effectiveness and applicability in real-life clinical practice.Methods: The search was performed using keywords ‘preoperative anxiety’, ‘management techniques’, ‘nonpharmacological’, ‘pediatric’ in PubMed and Google Scholar databases. Full-text original articles or reviews that were published during the last 5 years were selected. Anxiety management techniques were identified and further analyzed for advantages and disadvantages.Results: Patient education, educational videos and music seem to be the most effective and easy to implement in daily practice for adults. While playing rooms and interactive pop-up books are reasonable to manage preoperative anxiety for pediatric patients.Conclusions: The choice of nonpharmacological anxiety management methods is diverse. However, the availability and application in reality highly depend on numerous variables, such as costs, time availability, motivation of the medical team, cultural background, and preference of the patient.
Comparative biomechanical analysis of short transpedicular fixation methods for burst fractures in the thoracolumbar junction under rotational loads
Authors: S. Nekhlopochyn Oleksii , V. Verbov Vadim , V. Cheshuk Ievgen , V. Vorodi Milan , Yu. Karpinsky Michael , V. Yaresko Oleksandr
Published: February 2025

This study focused on evaluating the biomechanical behavior of short-segment transpedicular fixation for burst fractures at the thoracolumbar junction under pure rotational loading. A finite element model of the T9–L5 spinal segment, including a burst fracture at T12, was constructed to compare four fixation configurations: short and long pedicle screws, with or without an intermediate screw in the fractured vertebra.

The findings highlight that short-segment fixation without intermediate screws subjects both the metal hardware (rods and screws) and the adjacent vertebrae to higher stress levels. Notably, the rods can approach their tensile strength limit, indicating a higher risk of implant failure. Introducing an intermediate screw at T12, particularly in combination with longer screws, significantly reduces stress on both bony structures and the fixation system. This approach distributes the rotational load more effectively, minimizing localized overloading and consequently lowering the likelihood of fixation failure.

From a clinical perspective, these results suggest that a combination of longer pedicle screws and an intermediate screw may offer superior mechanical stability for burst fractures at the thoracolumbar junction under rotational stress. However, because the model employs several simplifying assumptions (e.g., homogeneous, isotropic material properties; quasi-static loading), further research is warranted to validate these findings and to explore the full spectrum of loading scenarios.

Solving continuous-discrete two-stage logistic problem of optimal partitioning-allocation
Authors: Kiseleva Е.M. , Prytomanova O.M. , Lebediev D.M.
Published: February 2025

The theory of optimal set partitioning is a powerful tool for solving infinite-dimensionaloptimization problems, including infinite-dimensional transportation problems where oneside, producers or consumers, is continuously allocated in a subset of n-dimensional space,for example, over a part ofa plane. A variation of the transportation problem is describedwhere the transportation of products is done in two stages, with intermediate transporta-tion points being integrated intothe model. First, products are transported from a set ofcontinuously distributed producers to a set of waypoints. Then, products are transportedfrom waypoints to a set of ultimate consumers. The defined problem consists of a classicdiscrete transportation problem and an infinite-dimensional transportation problem withoptimal partitioning-allocation of space. Such problem formulation significantly compli-cates the mathematical model but simultaneously allows us to get more optimal solutionsand solve problems that are closer to real-life cases of product transportation.A process of building a mathematical model is described, a method is proposed for solv-ing a two-stage logistic problem of optimal partitioning-allocation, and an algorithm isformulated based on the proposed method. Based on the formulated algorithm, softwareimplementation is developed thatsolves the two-stage problem in the case of two-dimensional space, that is on the plane. The software implementation consists of a compu-tational part that executes all necessary mathematical calculations, a graphical user inter-face part that allows to quickly and conveniently set initial conditions and parameters ofthe problem, and a visualizing part that conducts an interactive demonstration of interme-diate and final solutions of the problem. All parts are integrated into a single system. Ex-amples of solving several problems are shown for demonstration of the workof the pro-posed methodand explanation of key details.

Neural network approach to the selection of an observed system model
Authors: Mahas О.S. , Guk N.A.
Published: February 2025

This paper deals with a mathematical model for the deformation of a solid body, wheresensor-based observational data serve as input, and the system's internal properties andexternal influences constitute the output. The finite element method is used to numericallysolve the direct problem, determining system parameters at discrete points. Due to the ill-posed nature of the inverse problem, a quasi-solution approach is utilized. A multilayerneural network methodology is proposed, with each network trained on a specific class ofmodels. During real-time parameter identification, the reality model is treated assituational, meaning it is defined for a specific moment based on recorded input data. Theselection of the most appropriate model is guided by an equivalence criterion rooted in thereciprocity theorem.

Published: February 2025

Compreendendo a Educação como uma engrenagem essencial para a transformação social, investigar como se dá o debate de temas sensíveis nesse ambiente contribui no fomento de mudanças. Dentre as inúmeras questões em disputa, a invisibilidade feminina, principalmente na área acadêmica, é marcada por séculos de opressão e apagamento. Com o intuito de somar esforços ao movimento de valorização feminina, o presente artigo visa investigar como se dá a produção acadêmica sobre Mulheres e Ciência para a melhoria da Educação, mais especificamente, o Ensino de Ciências. Para tanto, foram analisados 735 artigos publicados entre 2017 e 2024 divididos em três periódicos de livre acesso: a Revista Educar Mais, o Caderno de Astronomia e a Revista Brasileira de Pesquisa em Ensino de Ciências. Desses, apenas 10 (1.3%) versavam sobre o tema, já produzindo o primeiro resultado que indica a baixa produção nesta área. Paradoxalmente, o interesse por esses artigos era em média 30% maior que os demais nos mesmos periódicos, indicando que há espaço para o crescimento do tema. Por fim, verificou-se que os artigos tinham mais acessos em março, indicando uma possível correlação entre o interesse e as comemorações do Mês das Mulheres. Pode-se então pressupor que esses eventos têm impacto positivo na discussão do tema, no entanto, entende-se que é preciso superar seu alcance para que Mulheres e Ciência seja um tema recorrente e perene.

Az uniós jog többnyelvű rendszerében a fordításnak és a fordításokat készítő szakfordítóknak kiemelt szerepük van, hiszen az uniós jog keletkezésének sajátosságai okán az egyaránt hiteles és hivatalos különböző nyelvi változatok tényleges előállítói lesznek. Tekintve, hogy az uniós jog nyelve a tagállami jogi nyelvek szókészletét használja, valamint az uniós jogi terminusok e jogi nyelvek részévé válnak, az uniós fordító nyelvi választásaival befolyásolhatja az egyes tagállamok nyelvpolitikáját is. Éppen ezért esetükben az általános fordítói kompetenciákon felül kiemelt szerep jut a különböző nemzeti, valamint az uniós jogrendszerek közötti átjárhatóságot felismerő transzfer, illetve interkulturális kompetenciáknak, a fordítóknak ugyanis nem csupán rendszerek közötti horizontális, hanem az uniós és a nemzeti jogrendszerek közötti vertikális fordítást is el kell végezniük.

Machine Learning Meets Network Management and Orchestration in Edge-Based Networking Paradigms": The Integration of Machine Learning for Managing and Orchestrating Networks at the Edge, where Real-Time Decision-Making is Crucial
Authors:   Independent Researcher, Yondertech Dallas, Texas, USA, Katragadda Santhosh , Kehinde Odubade ,   Independent Researcher, Yondertech Dallas, Texas, USA
Published: February 2025

Integrating machine learning (ML) into network management and orchestration has revolutionized edgebased networking paradigms, where real-time decision-making is critical. Traditional network management approaches
often struggle with edge environments' dynamic and resource-constrained nature. By leveraging ML algorithms,
networks at the edge can achieve enhanced efficiency, automation, and adaptability in areas such as traffic prediction,
resource allocation, and anomaly detection (Wang et al., 2021). Supervised and unsupervised learning techniques
facilitate proactive network optimization, reducing latency and improving quality of service (QoS) (Li & Zhang, 2020).
Furthermore, reinforcement learning (RL) models enable autonomous network orchestration, allowing edge devices to
adapt intelligently to fluctuating workloads and environmental conditions (Patel et al., 2019). However, challenges such
as data privacy, computational overhead, and model interpretability remain key concerns in deploying ML-driven
network orchestration at the edge (Chen et al., 2022). This paper explores state-of-the-art advancements, key challenges, and future research directions in ML-based edge network management, highlighting its potential to drive the next generation of intelligent, self-optimizing networks.
Limitations of Kanban in Large-Scale Project Management: A Case for Hybrid Approaches

This research article considers why Kanban, a widely used tool for work and workflow management
through visualization, in many instances is not enough alone for complex projects. Kanban is universally valued for its
simplicity in representing work progression and in providing groups with a mechanism for work ordering, but it can fall
short when complex planning, resource assigning, and timelines for a project enter into consideration. Citing current
studies and observations and interviews with leaders of projects, this study identifies both positive and negative factors
in using Kanban alone. Whereas Kanban can allow groups to effectively monitor work for a single day, we have found
that it is deficient in important factors for deeper requirements in a project, such as following a project's milestones,
dealing with a range of groups, and communicating a general direction for a project to everyone involved in it. As a
result, many leaders of a project have found that using Kanban in combination with other methodologies, such as with
Scrum or traditional methodologies for planning a project, can make larger, complex projects work effectively. In this analysis, the study identifies Kanban's specific strengths, as well as, weaknesses and suggests improvements in its use through integration with the additional tools and techniques.

In today's entertainment industry, the rapid development of technology has led to the emergence of a large number of innovative ways to create visual effects. However, the task of improving the efficiency of work with footage remains relevant and in demand. To record an actor's performance, one usually uses either a photogrammetric setup consisting of a bunch of cameras placed around the actor, or a helmet with fixed cameras filming the actor's face. Despite the undeniable advantages of this approach, compared to manual animation, it has a number of disadvantages. These include the cost of processing photogrammetry for each frame of animation and the subsequent stabilisation of the actor's head position. Problematic issues related to stabilisation of facial animation are caused by the need to adjust the position of the head in each frame of animation so that from frame to frame the head does not change its position in space, and the changes would occur only in the facial expressions of the actor. Despite the widespread use of photogrammetry to capture the faces of actors, the process of stabilising the position of the head is still complex and poorly automated. In the presented article the existing methods of stabilisation are considered: interactive nearest point algorithm (ICP), alignment by key points, ICP with weight mask and Rigid Stabilization of Facial Expressions proposed by developers of Disney studio. Their comparative analysis is carried out. A new stabilization method is proposed in which the finite element method is used to approximate the flesh behaviour more accurately. The deformation gradient, skull displacement and flesh deformation formulas are generated to implement this method. The results of approbation of the application and comparison of the performance of the proposed method with others are presented. The analysis of the results showed that the application of the developed method of character head stabilization is effective and allows to significantly improve the quality of the created computer animation.
Into the (Gendered) Blue: New Perspectives on Gender Equality and Participation in Blue Growth
Authors: Boström Magnus , Svels Kristina , Arias Schreiber Milena
Published: February 2025

In the context of the global adoption of the Blue Economy agenda, new challenges and opportunities emerge for gender mainstreaming in traditional male-dominated maritime industries. This thematic issue mobilizes knowledge on barriers and structural hindrances faced by women in the Blue Economy, from exclusionary workplace norms and hierarchies to inadequate support for work-life balance. These hindrances discourage women’s entry and retention in industries like fisheries, aquaculture, maritime transportation, and marine research. Lessons from the Nordic countries, which have significantly advanced gender equality and adopted numerous policies to enhance gender inclusivity, show that in the absence of effective implementation and evaluation of policy impacts, policies alone are not effective. Using gender as an analytical perspective reveals the importance of language and discourses in advancing gender inclusion, highlights issues of intersectionality across national borders, and exposes the need for Blue Justice alongside Blue Economy agendas. The collection of papers underscores the need for both systemic change and localized, tailored interventions. The methodological contribution exemplifies how discourse analysis unpacks societal norms, while ethnography reveals on-the-ground experiences of exclusion and resistance. Furthermore, tracking career trajectories provides data-driven insights into workforce retention, while interviews analyze the nuanced motivations and challenges women face. It is concluded that the agendas of the Blue Economy and gender equality could be indeed compatible, however, it must be acknowledged that the way these two can be simultaneously pursued remains a challenge that needs action.
Participatory Retrofitting Through Extended Planners in Tanzanian Urban Areas
Authors: Majogoro Manyama , Devisch Oswald , Magina Fredrick Bwire
Published: February 2025

The global endeavour to develop inclusive, safe, resilient, and sustainable cities and human settlements is paramount. Land use conflicts in urban areas persist as a critical issue among stakeholders in contemporary urban development discourse. This article examines the effectiveness of local mediation strategies in resolving land use conflicts within East African cities’ rapidly expanding metropolitan areas. It focuses explicitly on community-based leaders, referred to as “extended planners,” who foster sustainable communities through their involvement in conflict mediation. Unlike municipal authorities, whose responses can be slow, these grassroots leaders promptly engage in mediation efforts, demonstrating their critical role in urban land management. Through an ethnographic approach to data collection and analysis using the cultural-historical activity theory (CHAT), this study highlights the significant influence that extended planners have on conflict resolution and the improvement of community welfare. The findings indicate that residents generally report land use conflicts to the Mtaa Government Office, where mediation sessions are conducted. The grassroots leaders, acting as the primary mediators, facilitate these sessions with the conflicting parties and relevant stakeholders, utilising traditional methods and established mediation protocols. The study underscores the diverse roles of different actors in the mediation process, with grassroots (Mtaa) leaders mainly overseeing it. It concludes with a call for empowering these leaders with essential knowledge in urban planning and conflict resolution skills to increase the mediation sessions’ effectiveness.
ON QML-ESTIMATION OF MULTIVARIATE CONSTANT CONDITIONAL CORRELATION HYPERBOLIC GARCH MODELS
Authors: BAMBA Lanciné , SORO Brahima , KOUAKOU Konan Jean Geoffroy , HILI Ouagnina
Published: February 2025

The purpose of this paper is to present a theoretical methodology for estimation of a multivariate constant conditional correlation hyperbolic GARCH (CCC-HGARCH) model. The proposed model captures correlations between several time series exhibiting long memory property in volatility and finite variance observed on the same time period. This model extends the class of hyperbolic GARCH processes with finite variance to a multivariate framework. The goal of this work is to model volatility of multivariate hyperbolic GARCH processes by conditional covariance matrix based on a time invariant correlation matrix. We first provide a sufficient condition for the existence of strictly stationary solution of the CCC-HGARCH model. Secondly, the asymptotic properties of the quasi-maximum likelihood estimator are established.
IMPACT OF FERTILITY ON UNDER-5 MORTALITY IN BANGLADESH USING MACHINE LEARNING: INSIGHTS FROM BDHS 2017-18
Authors: Naznin Shayla
Published: February 2025

This study examines the relationship between fertility and under-5 mortality in Bangladesh using machine learning techniques. Utilizing data from the Bangladesh Demographic and Health Survey (BDHS) 2017-18, the study explores how factors like birth intervals, maternal age and total children ever born influence under-5 mortality. By applying advanced models like XGBoost, Random Forest and Gradient Boosting, we uncover hidden patterns and non-linear effects that traditional methods often overlook offering more comprehensive insights into how fertility impacts under-5 mortality. These insights provide actionable recommendations for public health policy focused on fertility management to reduce under-5 mortality rates. Machine learning adds value by identifying patterns critical to child health interventions.

Published: February 2025

This research aims to analyze the training needs faced by secondary school principals in Mexico City, with a focus on the areas of school management and leadership as the main research topics. This study is based on the diagnosis of the opinions and experiences of principals and teachers interviewed in educational centers. To conduct this analysis, an ethnographic methodology was used, employing a qualitative, descriptive, narrative, and participant observation approach. This methodology made it possible to document experiences of principals, teachers, and key informants, who collaborated in the study and contributed to understanding the reality and needs of each school context. The main findings reveal the need for professionalization and updating remains a concern for the teaching staff. Furthermore, it was found that management and leadership are oriented towards school improvement. However, a prevailing transactional leadership is observed in bureaucratic processes and the organizational culture of schools in the 21st century. It is concluded that despite the efforts of secondary school principals in Mexico City to enhance organization and educational performance, a substantial improvement in student performance is not observed. Additionally, although principals possess higher academic credentials and have improved the distribution of leadership, challenges persist in enhancing student performance due to a transactional approach that negatively impacts student motivation and identification with the school. It is recommended to revalue and professionalize the teaching profession.

This research explores the integration of an Immersive Learning Ecosystem (ILE) within International Virtual Communities of Practice (I-VCoP) for enhancing critical communication skills in multicultural societies. The study aims to (1) conduct a PRISMA and bibliometric analysis of existing research related to Virtual Communities of Practice (VCoP), (2) develop I-VCoP with an immersive learning ecosystem, and (3) assess the critical communication skills of users engaged in I-VCoP activities. The immersive learning ecosystem leverages Virtual Reality (VR) and Augmented Reality (AR) technologies in order to create dynamic learning environments that foster engagement, retention, and the development of essential communication skills. Participants from diverse cultural backgrounds were assessed on critical communication skills, including cognitive flexibility, cultural awareness, language awareness, emotional and relational competence, ethical and social responsibility, metacognitive skills, and interpersonal and leadership skills. The results indicate a high level of appropriateness across all phases of the I-VCoP activities, with “Active Participation” receiving the highest evaluation score. The assessment of critical communication skills shows that participants achieved “Highest Proficiency” levels overall, with notable strengths in cognitive flexibility, cultural awareness, and interpersonal skills. The findings suggest that the integration of ILE within I-VCoP is highly effective in fostering critical communication skills necessary for success in multicultural environments. The study underscores the potential of immersive technologies to revolutionize virtual learning communities by providing engaging and culturally responsive learning experiences.
Formas pronominais dos paradigmas de tu e de você em estruturas de complementação e de adjunção nos séculos XIX e XX: evidências históricas do português brasileiro escrito
Authors: Rumeu Márcia Cristina de Brito , Santos Davi José dos
Published: February 2025

Neste artigo, apresentamos panoramicamente as estratégias pronominais de 2ª pessoa do singular em estruturas de complementação e de adjunção produtivas em cartas pessoais oitocentistas e novecentistas. Com base nos parâmetros da sociolinguística histórica (Hernández-Campoy & Schilling, 2012), acompanhamos, a partir de amostras da escrita de redatores brasileiros, a diversificação de pronomes não-sujeito em estruturas de complementação e de adjunção. As estruturas de complementação prevalecem a partir de núcleos verbais que predicam as estruturas dativas. Identificamos formas nucleadas pelo você, em cartas de você-sujeito, o que nos sugere a confirmação da discussão de Lopes et al. (2009) acerca da inserção do você pelos demais contextos sintáticos (não-sujeito), com distintos níveis de produtividade. Constatamos ainda a convivência de formas do paradigma de tu com formas do paradigma de você até mesmo na escrita íntima de redatores desenvoltos em relação aos modelos de escrita e à depreensão dos parâmetros da norma-padrão.

PANORAMA DA PRODUÇÃO DE BATATA-DOCE NA SERRA DA IBIAPABA-CEARÁ
Authors: Martins Filho José Bonifácio , Távora Costa Raimundo Nonato
Published: February 2025

A batata-doce é uma hortaliça produzida em todas as regiões do Brasil, cuja atividade é muito relevante para a agricultura familiar. Considerada uma cultura rústica, muitos municípios apresentam produtividades relativamente baixas quando comparada ao seu real potencial produtivo. Nesse contexto, o objetivo dessa pesquisa foi analisar o panorama de produção da batata-doce na Serra da Ibiapaba-CE. Metodologicamente, a pesquisa é dividida em duas partes, sendo a primeira um levantamento de dados secundários da produção agrícola municipal e análise da evolução da produção de batata-doce em nove municípios pertencentes a Serra da Ibiapaba, seguida de uma tipificação do processo produtivo da hortaliça em uma propriedade rural familiar no município de Guaraciaba do Norte-CE. A Serra da Ibiapaba apresenta um sólido histórico de crescimento da produção da batata-doce que pode ser maximizada com aumento de produtividade. O sistema de produção da batata-doce na agricultura familiar é extensivo, sendo as técnicas de produção aplicadas um reflexo da falta de conhecimento técnico dos agricultores.

Klebsiella pneumoniae is an opportunistic pathogen related to several cases of healthcare-associated and community-acquired infections worldwide, especially in Brazil. Numerous studies have shown that isolated secondary metabolites, such as phenolic acids, have the potential to act against this problem. This study aimed to investigate the inhibitory potential associated with phenolic acids on growth and biofilm formation in clinical isolates of Multidrug-Resistant and Extensively Drug-Resistant K. pneumoniae (MDR/XDR-KP). Four clinical isolates from a public hospital in Recife, Pernambuco, Brazil, and a sensitive standard strain were used. The initial identification of the samples was carried out using VITEK®2 and BD-PhoenixTM 100 automation equipment, as well as the characterization of the resistance profile. The samples were then confirmed using the MALDI-TOF/MS technique. The Crystal Violet method was used to assess biofilm formation capacity. Four phenolic acids (gallic, trans-ferulic, caffeic, and 4-hydroxybenzoic) were used to evaluate the antimicrobial and biofilm-forming activities. The isolates were confirmed as K. pneumoniae species with MALDI-TOF/MS scores ranging from 2.459-2.083. The samples showed both MDR and XDR resistance profiles, and biofilm formation with different intensities. Of all the compounds tested, caffeic and trans-ferulic acids were the most effective, with growth and biofilm inhibition values of 70-85% and 70-90% using a concentration of 2 mg/mL, respectively. Notably, K. pneumoniae belongs to a group considered by the WHO to be a critical public health priority to be combated. In this context, the results showed that phenolic acids had a great potential impact on both bacterial growth and the biofilm-forming capacity of MDR/XDR-KP clinical isolates. This leads us to recognize the use of phenolic acids as a possible alternative in the fight against infections caused by MDR, XDR, and biofilm-forming bacterial species.

Severely ill children and newborns typically require a wide range of intravenous medications as part of specific therapies tailored to their developmental and growth characteristics. Intravenous medications for pediatric patients are dosed based on their weight and body surface area, and their response to drug therapy varies with age. Many drugs are originally developed for adults but are prescribed to children based on clinical experience and scientific publications, considering the severity of the condition. In this context, one such medication widely used in pediatric treatment since the 1970s is dobutamine hydrochloride, an inotropic drug with some vasodilatory effect. We aimed to validate High-Performance Liquid Chromatography to determine the concentration and stability of dobutamine hydrochloride. The dobutamine hydrochloride (250mg/ 2mL of water) was used as the sample. The parameters of analytical performance determined were selectivity, linearity, range, precision, accuracy, robustness and stability. The developed method has proved to be selective; linear in the range from 80% to 120% of the theoretical test concentration; precise in repeatability and intermediate precision; exact at the concentrations of 0.40, 0.50 and 0.60 mg/mL; robust with drug variations proportional to the deliberate changes caused in the composition and flow rate of MF, and column temperature; and stable for 24 hours after sample preparation. The High-Performance Liquid Chromatography analytical methodology for dobutamine hydrochloride was considered validated according to Resolution 899/2003 of the Brazilian Health Regulatory Agency (Anvisa).
