Standpoint Suicide Attempts Dalam Film Kembang Api
Authors: Rahmansyah Artaji , SM Anis Endang , Dianthi Martha Herinazwi
Published: July 2024

Suicide is a serious public health issue, with approximately 800,000 deaths each year according to the World Health Organization (WHO). In Indonesia, suicides are increasing, reaching 971 incidents by 2023. The movie "Kembang Api" raises the issue of mental health, suicide and emphasizes the importance of the value of life. This research aims to analyze the reasons behind the suicide attempt in the movie "Kembang Api" through the Standpoint perspective using Roland Barthes' semiotic analysis. The method used in this research includes analyzing the visual and verbal signs in the film to reveal the emotional and psychological burden experienced by the characters. The results show that these signs reflect heavy emotional and psychological burdens, reinforcing the representation of the characters' reasons for considering suicide. The film depicts the complexity of each character's emotions and struggles, emphasizing the importance of empathy, social support and understanding of mental health issues. Thus, the movie "Kembang Api" becomes a social mirror that invites viewers to understand and support individuals struggling with emotional and psychological problems.

(2024) Research & Development and Employees Productivity in Public Service of Nigerian Fourth Republic, Global Journal of Human Resource Management, Vol.12, No.4, pp.108-129 Abstract: This study examines the impact of research & development on employees’ productivity in public service of Nigerian fourth republic from 1999 to 2023. The annual data for the study is sourced from World Bank’s Development Indicators (WDI) and Central Bank of Nigeria Statistical Bulletin. The dependent variable is employee’s productivity proxied by total factor productivity while the explanatory variables are research & development expenditure as percentage of GDP, employee compensation proxied for income and institutional quality components of governance effectiveness and regulatory quality. The preliminary test of Augmented Dickey Fuller (ADF) unit root test reveals mixed order of integration among the series under consideration, which reinforces the choice of Autoregressive Distributive Lag (ARDL) as estimation technique. The ARDL bounds result reveal the existence of long-run among the series under consideration. On the result, the series of research & development exhibit negative and significant relationship with employee productivity in the Nigerian public service. The complementary series of employee compensation exert negative effect and significant impact on employee productivity. Also, governance effectiveness further exerts negative and insignificant nexus while regulatory quality demonstrates significant positive effect on employee productivity. This study concludes that research & development has not enhanced employee productivity in the Nigeria public service within the period considered. Therefore, the research recommends the need for government agencies and parastatals to make adequate provision for resources to fund high-quality training programs for public sector employees. This can include providing on-the-job training, skill development workshops, and opportunities for continuous learning and professional development.
Promoting Strategic Relationship Management Amongst Stakeholders for Organizational Success: A Case of Tertiary (University) Students in Ghana
Authors: Kwadade-Cudjoe Francis
Published: July 2024

Strategic management entails planning, organizing, developing, controlling and implementing activities effectively within the organization to achieve corporate strategic goals and objectives. Furthermore, strategic management involves effective resource allocation, reviewing internal processes and monitoring the external factors that might impact the enterprise. It is in this vein that when the relationship management of stakeholders within the entity is not handled / tackled expertly and there are squabbles and nuances, the success of the business would be jeopardized. This would lead to loss of investment from shareholders, which consequently, would cause irreparable damage and possibly, demise of the enterprise. Management should therefore, be circumspect to alleviate all misunderstandings amongst the stakeholders for transparency in all facets of the organization, and allow the conditions of service to work as endorsed and agreed upon by the stakeholders. Moreover, communication should be effective and allowed to flow seamlessly with harmony amongst the stakeholders and effective decision making by management to promote a viable organization for competitive advantage.

Authors: Eshteiwy Mohamed Abed
Published: July 2024

The study aimed to demonstrate the impact of servant leadership in managing the organizational impression among employees in private Palestinian universities. It followed the descriptive analytical approach and applied its vocabulary to a simple random sample of (388) employees in private Palestinian universities (University of Palestine, Israa University, Gaza University), using A comprehensive survey method for all members of the total population of (578) employees. The questionnaire and interviews were used as tools for collecting data.The results showed that the servant leadership came in at a significant 77.52%. The level of management of organizational impression management came in a large percentage (78.23%). The dimensions of the servant leadership (Empowerment, Emotional Containment) in managing the organizational impression were proven to be significant (70.6%), but did not demonstrate the dimensions (interest in subordinates, community service). Differences in examiners' responses to (Servant Leadership, Management of Organizational Impression) were not demonstrated depending on variables (Type of Job, Gender, Age Group, Years of Service And Academic Degree), but were found depending on the variable University Name between Israa University and Gaza University was for the benefit of Israa University.The study recommended enhancing attention to subordinates in clear ways that employees can feel and mentally link them to the services provided by the university community.
Kaleidoscope of a Self: Byron’s Ravenna Journal
Authors: Schoina Maria
Published: July 2024

The Ravenna Journal (written 4 January – 27 February 1821) documents a critical and complex period of Byron’s life. In light of the codependent and fluid relationship between Byron’s poetry and prose, this essay explores the literary value and poetics of the Journal and its function as a testing ground for Byron’s experimentation with style, tone, and language. I also place the Journal within Byronic self-representation and the era’s strong autobiographical impulse and suggest that the diary does not only reflect on the poetry/politics dilemma but reveals versions of Byron’s selfhood in a kaleidoscopic mode, one which resembles the make-up of
Don Juan
. In this way, the narrated self emerges as a refracted identity and an aggregate of moods and contradictions which, however, interrelate and are given shape and purpose through the regularity and conventions of the journal. Despite the limitations and challenges it poses to the reader due to its mediated and excised form, the essay argues that the Ravenna Journal enhances our understanding of the Byronic self and enriches our appreciation of the literary artistry of Byron’s prose.

Les Épistémologies du Sud et l’éducation émancipatrice : réflexions de recherche
Authors: Barbosa de Oliveira Inês
Published: July 2024

Boaventura de Sousa Santos possède un vaste travail dans lequel il développe une critique politique et épistémologique de la modernité pour aboutir à la formulation de ce qu'il appelle les épistémologies du Sud. Ce travail est utilisé par des chercheurs de différents champs scientifiques et présente un grand intérêt pour les chercheurs et les mouvements sociaux intéressés à la réflexion sur l'émancipation sociale et à la contribution que différentes études scientifiques et pratiques sociales à elles associées peuvent apporter. Dans ce texte, nous présentons un peu de la trajectoire de formulation des épistémologies du Sud, en essayant de montrer leur utilité pour les recherches en sciences de l’éducation axées sur la quête de la justice cognitive et sociale et d’une plus grande présence des pratiques sociales de citoyenneté horizontale, éléments fondamentaux des épistémologies du sud et de l’émancipation sociale.
Épistémologies du Sud : la ligne abyssale séparant les exclusions radicales et non radicales
Authors: Sousa Santos Boaventura de
Published: July 2024

Cet article aborde l’un des thèmes fondamentaux des épistémologies du Sud, telles que je les formule depuis 2009. Il s’agit de la ligne abyssale et de la manière dont elle crée une duplicité ontologique qui divise les êtres humains entre ceux qui sont considérés comme pleinement humains et traités comme tels, et ceux qui sont considérés comme sous-humains et traités comme tels. Cette dualité génère deux types d’exclusion sociale. J’analyse l’impact de cette dualité sur les luttes contre l’injustice sociale et la discrimination
Le corps queer dans l’enseignement
Authors: Védie Marjolaine
Published: July 2024

Dans un contexte de tensions croissantes autour de l’enseignement des questions de genre à l’école et de lutte contre les LGBTQI+phobies au sein des établissements scolaires, la posture des enseignant·es queer est, plus que jamais, à la fois centrale et ignorée. Iels se trouvent tiraillé·es entre une injonction à la neutralité, assignant à la dissimulation de son identité, et leur identité queer marginalisée par l’hétéronormativité scolaire, modèle qu’on leur demande de transmettre alors même qu’il leur est attentatoire ainsi qu’à leurs élèves. Leur double statut pose ainsi la question de l’efficacité des luttes contre les LGBTQI+phobies à l’école, mais également celle de la perpétuation de normes qui rendent par essence ces luttes obsolètes et superficielles.
Un essai d’approche philosophique clinique des terrains à l’Hôpital de Panzi en République démocratique du Congo
Authors: Fleury Cynthia , Tourette-Turgis Catherine , Mukwege Denis , Lauffenburger Mégane
Published: July 2024

Dans le cadre d’une commande d’évaluation de l’impact des dispositifs d’art thérapie mis en place par l’Hôpital de Panzi, en République Démocratique du Congo à destination de femmes concernées par des situations de violences sexuelles basées sur le genre, nous travaillons à l’élaboration un protocole de recherche en evidence-based humanities, jugé légitime et pertinent pour les équipes et les patients locaux, compatible avec les standards de l’évaluation scientifique internationale. Basé sur une approche philosophique clinique des terrains, nous avons commencé par répondre à la question : Comment faire laboratoire quand on est un réseau éparpillé dans le monde au niveau géographique et au niveau culturel ? Cet article décrit le récit d’une recherche, combinant une revue des écrits disponibles, la théorie des acteurs-réseaux, des apports de la clinique du trauma et de la psychothérapie institutionnelle, des méthodes qualitatives telles que la géolocalisation des concepts, et une réflexion critique sur les ingénieries d’implantation et la « revanche des contextes » (De Sardan, 2021). Notre recherche s’arrime à un postulat : le laboratoire de production de connaissances sur les effets du soin ne se cantonne pas aux espaces où ils sont délivrés, mais doit prélever aussi les traces de circulation de connaissances depuis « l’extérieur » du soin, en allant interroger les acteurs qui ont contribué à la fabrique de Panzi, devenu de fait, l’objet d’un récit collectif.
Biopolitique et éducation dans l’Espagne franquiste : le cas des personnes handicapées
Authors: Cayuela Sanchez Salvador
Published: July 2024

Après la fin de la guerre civile espagnole en 1939, le nouveau régime du général Franco devait articuler une forme caractéristique de biopolitique capable de générer : d’une part, la légitimité du système politique parmi la population espagnole; et d’autre part, l’augmentation de la puissance de l’Etat. Ces objectifs ont été poursuivis à travers la création d’une série de dispositifs disciplinaires et de mécanismes de régulation qui vont perfectionner leur fonctionnement pendant près de quarante ans. Parmi ces mécanismes, l’éducation a joué un rôle fondamental. En prenant en compte tous ces éléments, mon objectif dans cet article sera, en premier lieu, de définir le concept de biopolitique et ma manière de l’appliquer à l’analyse du régime de Franco. Deuxièmement, j’expliquerai l’importance de l’éducation et de ses différents dispositifs dans l’ensemble de cette biopolitique franquiste, dans sa mission particulière de gouverner les esprits et les corps des Espagnols. Et finalement, je concentrerai toutes ces analyses dans le cas de l’éducation des personnes handicapées pendant la période exposée.
La décolonisation du concept de frontière : vivre la frontière, habiter sur la Raya du Sud ibérique
Authors: Hernández León Elodia
Published: July 2024

Cet article analyse de manière critique une frontière étatique, la Raya (frontière) du Sud ibérique. Nous partons de la nécessité de décoloniser le concept de frontière, pour permettre l’émergence d’une écologie de savoirs utilisée par des populations frontalières, à travers l’analyse des expériences et des expressions de la culture frontalière. Nous illustrons notre approche par des notes ethnographiques de notre recherche menée dans une commune située à la frontière portugaise/espagnole du Sud ibérique pour montrer comment le dispositif frontalier affecte la santé et, finalement, le parcours vital des habitants des deux marges de la frontière.
Phytochemical characterization, antioxidant, and antimicrobial activities of the Ayurvedic polyherbal formulation Mentone
Authors: Inavally Akshata T. , D’Souza Deepthi , Sadananda Monika
Published: July 2024

Introduction:

Polyherbalism is extensively practiced in traditional medicine and constitutes complementary and alternative medicine (CAM). Greater therapeutic efficacy ensues from the synergistic effects of constituents mediated by pharmacodynamic and pharmacokinetic interactions and safety at higher dosages. Very few studies exist on mechanistics, despite rampant polyherbal use. Mentone tablet is a polyherbal constituting equal components of Centella
asiatica (L.) Urban, Convolvulus
pluricaulis Choisy, Glycyrrhiza
glabra L., and Tinospora
cordifolia (Willd.) Miers ex Hook. F. and Thomson.

Materials and Methods:

Proximate and phytochemical analysis followed by quantification of polyphenolics was carried out. Asiatic acid, berberine, betaine, and glycyrrhizin were characterized using ultraviolet–high-performance liquid chromatography (UV-HPLC). Antioxidant activity was determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH) quenching activity, ferric reducing ability of plasma (FRAP) assay, and hydrogen peroxide (H2O2) scavenging activity. Antimicrobial activity was determined by Kirby–Bauer disc diffusion microbial susceptibility test followed by minimum inhibitory concentration (MIC) method.

Results:

Aqueous extraction using Soxhlet generated maximum yield. Proximate analysis yielded 52.96% ash, pH ranged from 5.75 to 5.76, and 5% moisture content. Qualitative analysis revealed the presence of inorganic substances and phytochemicals: saponins, reducing sugars, terpenoids, starch, glycosides, and triterpenoids. Phenols were higher in aqueous, while flavonoids and tannins were higher in ethanolic extracts. HPLC revealed the presence of glycyrrhizin and asiatic acid. Mentone extracts at 100 µg/mL showed the highest antioxidant activity in DPPH, FRAP assays, and H2O2 radical scavenging. Ethanolic extracts above 50 mg/mL demonstrated antimicrobial activity against Staphylococcus aureus ATCC 25923 and Klebsiella
pneumoniae ATCC 700603.

Conclusion:

Mentone contains phytochemicals with antioxidant and antimicrobial activities. With active constituents such as asiatic acid and glycyrrhizin, Mentone could constitute a CAM for oxidative stress-induced diseases, including neurodegeneration.

Authors: Narwaria Avinash , Chakrabarty Anirban Kr , Bishayee Shreya , Mohanty Shambo , Banerjee Dipankar , Sharma Swapnil , Katiyar Chandra Kant , Dubey Sunil Kumar
Published: July 2024

Background:

Curcuma longa L., commonly known as turmeric has a long history as a medicinal plant. Ancient medicinal practices have been using it for its potent anti-inflammatory, antioxidant, and antimicrobial activities. The primary phytoconstituent, Curcumin exerts significant influence over skin health and the management of dermatological conditions. Its anti-inflammatory and antioxidant attributes ameliorate skin disorders such as acne and psoriasis. Furthermore, this active compound also facilitates collagen synthesis, thereby contributing to skin revitalization and its overall maintenance.

Aim and Objectives:

This study aimed to formulate, optimize and evaluate a herbal sustained-release topical hydrogel employing Curcuma longa methanolic extract (CE) for improving skin health.

Material and Methods:

The phytoconstituents in the CE were screened both quantitatively and qualitatively. Following confirmatory tests and method development, a sustained-release hydrogel containing CE was formulated. Further, the pharmacological properties of an enriched CE were explored by performing various in vitro assays.

Results:

The CE encompassed qualitative identification of several phytoconstituents and quantitative assessment of curcuminoids. CE also exhibited remarkable anti-oxidant properties and anti-inflammatory attributes. The optimized CE containing sustained-release hydrogel showed approximately 90% drug loading with sustained release over 24 hours along with better sun protective capabilities and wound healing efficacy as compared to the pure extract.

Conclusion:

This research proposes a formulation of a topical hydrogel with a sustained-release profile for the holistic management of several skin-related diseases.
Fuel Economy Improvement by Optimized Intake-Port Configuration and Comprehensive Specifications
Authors: TAKI Isato , OHIRA Tetsuya
Published: July 2024

In order to improve fuel consumption of a four-stroke engine while maintaining the original power output, modifications to several components were tested. First, three types of modified intake port configurations were examined: swirl, tumble and swirl-tumble types. These configurations were examined for their effect on in-cylinder vortex intensity and flow coefficient, which were good indicators of Brake Specific Fuel Consumption (BSFC) and Brake Mean Effective Pressure (BMEP). The tumble-type port showed a good balance of both factors and led to low BSFC and high BMEP. Second, the effect of a bowl-cavity modification to the piston crown, together with the tumble port configuration, enhanced BSFC improvement in high load conditions. This combination also allowed over-lap of valve-timing to be shortened, in order to reduce BSFC in low load condition. Finally, a comprehensive modification package, which included long-duration spark ignition, high compression ratio and a cylinder head with revised squish area, together with the above specifications, were effective in all test conditions and achieved a fuel consumption reduction of 22.6% in the ECE40 driving-mode cycle.
Design for Good Motorcycle Handling Qualities
Authors: Sharp R.S.
Published: July 2024

An overview of the handling qualities of motorcycles is given. Firstly, the problems are discussed from a practical standpoint with reference to responses to steering control inputs, to self-excited oscillations arising from instabilities and to motions caused by road irregularities. The theoretical basis for understanding the behaviour is then outlined, with sections on the analysis problem itself, on small perturbations from straight running, on small perturbations from steady turning and on general motions. The need for advanced, automated approaches to modelling is stressed and relationships between design and operating conditions and steering behaviour are described. A brief account of experimental work on motorcycle steering responses is included and conclusions are drawn relating to motorcycle design issues.

Authors: Koc Pinar ,   Cumhuriyet University, Faculty of Architecture, Fine Arts and Design, Sivas, Turkey, Tuztasi Ugur ,   Cumhuriyet University, Faculty of Architecture, Fine Arts and Design, Sivas, Turkey
Published: July 2024

Architectural education inherently requires continuity. The transformative power of the world, which people have experienced in the last 5 years with crises such as pandemics and earthquakes, has changed and forced the form, style and tools of this continuity. Architectural design education, which was shaped on the axis of a studio culture, had to cope with the ruptures and transitions of a new phase. This case report aims to convey an experience that brought together the adaptation of face-to-face education of the students after the online education and the section-model practice that the studio tutors have experienced before. Since the study tries to repair the correlations between the continuity, ruptures and transitions of architectural design education, integration of section and model has been re-engaged in the studio. The study group consists of architecture students who switched to online education after the February 2023 earthquakes and started face-to-face education again in the fall semester of 2023/2024. As a result, well-thought models, few experiments on the models and quick transfers to digital programs were revealed as three main tendencies in the studio. In conclusion, the adaptation of the student on the axis of continuity and to reinforce the design productivity, design problem-solving skills and the habit of doing design research tried to provide.
Analysis of support vector machine and random forest models for classification of the impact of technostress in covid and post-covid era
Authors: James Gabriel , Umoren Ime Jonah , Inyang Saviour , Inyang Saviour , Aloysius Oscar
Published: July 2024

This study addresses the growing concern of technostress, a condition caused by the overwhelming use of digital technologies, exacerbated by the COVID-19 pandemic. The researchers developed a predictive model using machine learning algorithms, Random Forest (RF) and Support Vector Machine (SVM), to assess and manage technostress levels. The model considers factors such as age, gender, technology usage hours, and technological experiences to classify stress levels into high, moderate, and low categories. The study collected data through a questionnaire administered to knowledgeable respondents, using a non-probabilistic sampling approach. The results showed that both RF and SVM algorithms achieved high accuracy in classifying technostress, with SVM performing slightly better (94.5% vs 84.50%). The model’s effectiveness in predicting stress levels for users with varying degrees of stress is a significant contribution to the field. The research also developed an interactive user interface to facilitate user engagement with the model, promoting stress management and well-being in a technology-driven society. The study’s findings provide valuable insights into the challenges posed by technostress and offer a solution for mitigating its effects. The use of machine learning algorithms to classify gender based on the dataset demonstrates the model’s potential applications in various areas. Overall, this study demonstrates the importance of addressing technostress in the digital age and provides a valuable tool for managing stress levels. The development of predictive models like this one can help individuals and organizations mitigate the negative impacts of technostress, promoting a healthier and more sustainable relationship with technology.
Lidocaína em cirurgia oncológica: o papel do bloqueio em canais de sódio com tensão: uma revisão narrativa
Authors: Costa Iury Luiz Zordan , Andrade Júnior Rodney Júlio de , Oliveira Giovanna Borba
Published: July 2024

Introdução: A busca por novos métodos para reduzir complicações cirúrgicas tem levado a estudos sobre a utilização da lidocaína como uma potencial droga anti-metastática. Os canais de sódio com tensão estão associados a células tumorais e, através de potenciais de ação e gradientes, estão relacionados com a dinâmica tumoral. Potenciais de ação, nos quais os canais de sódio estão envolvidos, podem migrar e determinar a progressão das células tumorais. Novos estudos demonstram que o uso da lidocaína, através de suas propriedades imunomoduladoras e bloqueio de canais de sódio, pode diminuir a recorrência de câncer. Objetivo: Analisar a associação da lidocaína, através do bloqueio dos canais de sódio, na diminuição de células oncogênicas e anti-metastáticas. Materiais, Sujeitos e Métodos: Para a elaboração deste artigo foram utilizados materiais impressos, artigos científicos, além de consultas em sites como Pubmed, SciELO, abrangendo o período entre 2014 e 2024. Resultados e Discussão: Estudos mostram a possibilidade de redução de metástases através do uso da lidocaína em procedimentos cirúrgicos. Estudos em animais indicam que a lidocaína pode diminuir a metástase ao bloquear os canais de sódio, alterando o padrão oncogênico e metastático. Considerações Finais: A lidocaína, em estudos pré-clínicos, mostrou ser uma candidata promissora para uso em cirurgias oncológicas, bloqueando canais de sódio e outros receptores tumorais, diminuindo a cinética tumoral. Mais estudos são necessários para maior compreensão e potencial uso clínico em procedimentos oncológicos futuros.

Published: July 2024

Introdução: Há mais de 30 anos, a comparação entre anestesia neuroaxial e a anestesia geral vem sendo estudada por diversas especialidades médicas. No entanto, poucos estudos conseguiram alcançar significância estatística e afirmar a superioridade de uma sobre a outra. No presente estudo, reunimos alguns artigos para que a questão possa ser melhor debatida, focando em procedimentos na metade inferior do corpo, onde a anestesia neuroaxial é amplamente empregada em cirurgias ortopédicas, ginecológicas/obstétricas e abdominais. Materiais, sujeitos e métodos: Estes estudos foram selecionados a partir das bases de dados PubMED, SciELO e Cochrane entre 1992 e 2023. Resultados e discussão: A maioria dos estudos indica uma melhor avaliação da anestesia do neuroeixo na metade inferior do corpo em relação à anestesia geral quando comparadas em aspectos como perda sanguínea intraoperatória, incidência de trombose venosa profunda e eficácia do bloqueio da dor pós-operatória. No entanto, não foi comprovada diminuição do tempo de internação ou de eventos graves entre as duas opções. A anestesia neuroaxial demonstrou mais casos de hipotensão arterial durante as cirurgias. Considerações finais: Para escolher o melhor método de anestesia, muitas considerações devem ser ponderadas, como o perfil hemodinâmico do paciente, o grau de invasão da cirurgia, os efeitos pós-cirúrgicos e a habilidade técnica dos envolvidos. A escolha deve ser individualizada para cada caso. Mais estudos precisam ser realizados para que a escolha entre a anestesia geral e a anestesia do neuroeixo possa ter indicações seguras nas cirurgias realizadas.

Published: July 2024

Introdução: A hipertensão arterial (HA) e a obesidade são grandes problemas mundiais de saúde e muitas vezes estão interligadas, representando fatores de risco significativos para doenças cardiovasculares e aumento da morbimortalidade. No Brasil, 22% da população é obesa ou apresenta sobrepeso. A obesidade tem etiologia multifatorial, envolvendo componentes genéticos, ambientais, emocionais e de estilo de vida que levam a um estado pró-inflamatório crônico. Há vários mecanismos propostos para a relação entre HA e obesidade, como aumento do angiotensinogênio, aumento da atividade simpática, compressão renal devido à gordura, disfunção endotelial, apneia obstrutiva do sono, aumento de deposição de gordura nos vasos levando a rigidez vascular e aumento da resistência periférica, entre outros. Materiais e Métodos: Para a elaboração deste artigo de revisão, foram consultados artigos científicos, informes das sociedades de cardiologia e manuais do Ministério da Saúde. Resultados e Discussão: Esta revisão mostra a estreita relação entre obesidade e HA, bem como o impacto dessa associação na morbidade e mortalidade, uma vez que causa alterações cardiovasculares significativas. Considerações Finais: A intervenção em mudanças no estilo de vida, e quando necessário, medicamentosa ou cirúrgica para perda de peso causa redução significativa nos níveis pressóricos e consequentemente no risco de morte cardiovascular. Sendo assim, além da prevenção secundária e terciária, políticas de rastreio para intervenção precoce se tornam um fator de grande importância em saúde pública.

Authors: Medeiros Thiago Rabelo de , Nascimento Luíza Pinheiro , Alves Natana Carol , Medeiros Julya Sabino , Negri Mellina Bordim
Published: July 2024

Introdução: O termo Doença Renal Crônica (DRC) engloba um espectro de processos fisiopatológicos associados à função renal anormal e ao declínio progressivo da taxa de filtração glomerular (TFG). Acredita-se que o aumento da rigidez arterial esteja associado à incidência e progressão da DRC, assim como à mortalidade cardiovascular. Entretanto, estudos detectaram associações fracas ou nenhuma associação. O presente artigo tem por objetivo realizar uma revisão da literatura do conhecimento atual sobre a correlação entre rigidez arterial e a previsão de DRC. Materiais, sujeitos e métodos: Para a elaboração deste artigo de revisão, foram consultados artigos científicos e artigos de revisão publicados e referenciados na Medline/PubMED, SciELO e Cochrane entre 2010 e 2023. Resultados e Discussão: Evidências mostraram uma forte correlação entre o aumento da rigidez arterial [foi utilizada a velocidade da onda de pulso carotídeo-femural (VOPcf) como parâmetro] e a incidência de DRC, sendo a magnitude dessa associação mais importante em pacientes normotensos e não diabéticos. Considerações finais: A maior VOPcf mostrou-se um importante fator de risco para DRC e sugere um impacto aumentado em indivíduos sem diabetes e hipertensão.

Authors: Benetti Larissa Regina Macedo , Oliveira Fátima Lemes de , Brasão Izabella Boaventura Teodoro , Castro Arthur Marques de
Published: July 2024

A melatonina é um hormônio sintetizado na glândula pineal e participa na organização temporal de ritmos biológicos. Nos últimos anos, expandiram-se as pesquisas em relação às diferentes atuações da melatonina no corpo humano, identificando-se ações de regulação nos sistemas cardiovascular, imunológico e, principalmente, endócrino. Por isso, o objetivo deste trabalho é apresentar a relação da melatonina nos pacientes diabéticos e suas repercussões clínicas. Para tal, foram selecionados artigos obtidos a partir da plataforma SciELO e Associação Médica Brasileira. Nos estudos, a melatonina melhorou os danos causados pelo Diabetes Mellitus em tecido cerebral, diminuindo a glicemia e a resistência insulínica, além de reduzir a ocorrência de outros distúrbios metabólicos que podem culminar em obesidade devido à sua ação anti-obesogênica. A melatonina apresenta características anfifílicas, ou seja, pode se difundir em meios aquosos e lipídicos, sendo assim encontrada em todo o organismo, principalmente nos tecidos periféricos e no sistema nervoso central.

Authors: Cerqueira Giulliane da Silva , Borges Lilian Rodrigues Coelho , Parente Sara de Alencar
Published: July 2024

Introdução: A doença falciforme é a hemoglobinopatia mais comum no Brasil e no mundo. Até a década de 70, devido à pouca importância dada ao cuidado e manejo da doença, estava associada a alta mortalidade materna e fetal. Atualmente, observa-se uma redução expressiva nas taxas de mortalidade materna e fetal, em função das melhorias nas técnicas de rastreio neonatal e medidas preventivas, como vacinação e profilaxia antibiótica desde o nascimento. Objetiva-se, neste artigo, elucidar as diversas complicações exacerbadas da doença falciforme durante a gestação e a importância dos cuidados prévios para uma gravidez mais segura, com redução das morbimortalidades neste período. Materiais, sujeitos e métodos: Este artigo de revisão de literatura foi embasado em artigos científicos e no manual do Ministério da Saúde, publicados e referenciados nas plataformas PubMed, BVS e SciELO no período de 2002 a fevereiro de 2022. Resultados e discussão: Entretanto, mesmo com todos os avanços, as alterações fisiológicas enfrentadas pelas mulheres durante a gestação são agravadas em pacientes com doença falciforme, resultando no aumento da incidência de complicações como crise vaso-oclusiva, síndrome torácica aguda e eventos tromboembólicos. Complicações obstétricas, como pré-eclâmpsia, eclâmpsia e abortos espontâneos, e neonatais, como crescimento intrauterino reduzido, ainda permanecem elevadas em comparação à população em geral. Considerações finais: Considerando que a doença falciforme tem um impacto significativo nas mulheres grávidas, o planejamento antes da concepção, o cuidado durante a gravidez e novos estudos sobre o assunto são imprescindíveis para a redução das complicações neste período.

Published: July 2024

Objetivo: O artigo tem como objetivo buscar maneiras de promover a saúde mental em gestantes, visto que o sofrimento psicossocial e pós-neonatal da gestante é um fator primordial para o acompanhamento da saúde da mulher a longo prazo. Dessa forma, são avaliadas estratégias como mindfulness, yoga, como o uso de tecnologias pode impactar a vida da mulher e quais estratégias trazem mais benefícios. Método: Para a elaboração dessa revisão de literatura, foram utilizados artigos científicos e de revisão publicados entre os anos de 2014 a 2024, que são referenciados no PUBMED e SciELO, incluindo publicações em inglês e português. Resultados: Os estudos revelaram diferentes resultados quanto à saúde mental da mulher grávida, pois muitas delas não têm acesso a ferramentas que possam atuar de maneira benéfica para uma gestação mais saudável. Outra parte do grupo que estava disposto à intervenção e controle teve tendências à redução da ansiedade e de sintomas depressivos. Conclusões: Considerando a falta de medidas preventivas para a depressão perinatal em nações com economias menos desenvolvidas, é crucial realizar um estudo definitivo e controlado para avaliar a eficácia e aceitação de intervenções como o uso de tecnologias e terapias comportamentais nas gestantes.

Transformational leadership is a process in which leaders and followers help each other to advance to a higher level of morale and motivation, creating significant changes in the lives of people and organizations. The purpose of the study was to investigate the influence of individualized consideration style on organization performance in private universities in Nairobi City County, Kenya. The objective that guided the study was to: establish the influence of individualized consideration on organizational performance in private universities in Nairobi City County, Kenya. The study used Transformational Leadership Theory by Burns (1978) and the conceptual framework was based on the relationship between individualized consideration style and organizational performance. The sample comprised of 288 lecturers and 7 Deans of Academic Affairs of the chartered private universities, and questionnaires and interview guides were used to gather data. Validation of the questionnaires was through Cronbach’s Alpha and the use of expert judgement. The coefficient value was 0.879 at alpha = 0.05. Data was analyzed using both descriptive and inferential statistics, and the regression analysis showed a strong relationship between individualized consideration and the performance of private universities. The results revealed a positive and significant relationship between individualized consideration (β = .370, p<.05). It was concluded that offering leadership support and advice, mentorship, career development, and solving individual needs among their employees influences performance. The following recommendations were made: the management of private universities ought to offer leadership support and advice to their employees as this is important in improving their performance. Furthermore, they should realize that in order to realize higher performance for their institutions they need to ensure that the leaders in the institutions act as both mentors and coaches for the employees and recognize their contributions to the organization. The Deans of Academic Affairs need to attend seminars and training in transformational leadership so that they can be well-versed in transformational leadership skills, responsibilities, and characteristics.

Published: July 2024

Stroke remains a leading cause of disability and death worldwide, with significant public health implications. Ischemic stroke is classified into various subtypes based on etiology, including large-artery atherosclerosis, small-vessel occlusion, and cardioembolism. The middle cerebral artery is often the most affected. The concept of the ischemic core and penumbra is crucial in understanding stroke pathology, where the core suffers irreversible damage, and the penumbra is at high risk if reperfusion is not timely. Genetic predispositions play a significant role in ischemic stroke, with heritability estimates around 37.9%. Monogenic causes account for 1-5% of cases, while polygenic factors are more prevalent. Genome-wide association studies (GWAS) have identified numerous genetic loci associated with ischemic stroke, revealing the complex genetic architecture of the disease. Molecular pathways such as neuroinflammation, excitotoxicity, oxidative stress, apoptosis, and autophagy are involved in the pathophysiology of ischemic stroke. Understanding these pathways offers potential therapeutic targets. This review aims to synthesise recent genetic studies and provide insights into future directions for research and clinical practice in ischemic stroke, emphasising the importance of personalised medicine and targeted therapies.

Published: July 2024

The incorporation of blockchain technology in supply chain management has emerged as a revolutionary solution, offering enhanced transparency, efficiency, and security across the entire supply chain network. This study presents a thorough examination of the intersection between supply chain management and blockchain, emphasizing the key advantages, obstacles, and recent advancements. The integration of blockchain in supply chain management tackles crucial issues such as traceability, origin, and trust. Through the establishment of a decentralized and unchangeable ledger, stakeholders throughout the supply chain obtain immediate insight into the flow and condition of products. This level of transparency not only minimizes the risk of fraud and counterfeiting but also strengthens the overall resilience of the supply chain. The proposed framework will leverage Blockchain technology to establish a transparent and tamper-resistant record of every transaction and event across the supply chain lifecycle. Every participant in the supply chain ecosystem, including suppliers, manufacturers, distributors, logistics providers, and consumers, will be able to access a shared ledger, facilitating real-time monitoring of the movement and status of products.
