Published: October 2024

O avanço da ciência, do conhecimento médico e das tecnologias ao longo dos séculos foram fatores fundamentais para determinar a evolução histórica dos hospitais. Do século XVIII aos dias atuais muitas transformações ocorreram nos modelos assistenciais e na própria edificação, influenciados pelas revoluções industriais e pelo surgimento de novos conceitos de saúde. Este estudo propõe descrever o processo de transformação da saúde e dos hospitais, dando enfoque para as evoluções ocorridas a partir das revoluções industriais e o processo de transição da Saúde 1.0 para a Saúde 4.0. A abordagem metodológica consiste em uma pesquisa exploratória a partir de uma revisão da literatura. As edificações hospitalares passaram ao longo dos séculos por uma revolução, saindo de um hospital com estrutura de separação e exclusão dos doentes em relação à sociedade, passando pelo hospital terapêutico voltado para o diagnóstico e cura e chegando ao século XXI com o hospital tecnológico voltado para a recuperação das pessoas e pautado em uma arquitetura humanizada, sensível e centrada no ser humano. O futuro é incerto, mas é possível vislumbrar estruturas hospitalares aliando humanos e tecnologias em prol da assistência à saúde de qualidade e voltada para a prevenção de doenças, tornando os espaços promotores de qualidade de vida.

Introdução: A abordagem cirúrgica de varizes em mulheres grávidas com insuficiência venosa crônica é um tema complexo que envolve considerações tanto obstétricas quanto vasculares. Durante a gravidez, as alterações hormonais e o aumento da pressão venosa contribuem para a exacerbação de sintomas venosos, levando muitas mulheres a buscar intervenções. A insuficiência venosa crônica pode resultar em desconforto significativo, comprometendo a qualidade de vida e, em alguns casos, afetando a saúde fetal. As opções cirúrgicas, incluindo a flebectomia e a ablação, levantam questões sobre a segurança e a eficácia quando realizadas em um contexto gestacional, exigindo uma análise cuidadosa dos riscos e benefícios para a mãe e o bebê. Objetivo: Analisar estudos recentes sobre a abordagem cirúrgica de varizes em mulheres com insuficiência venosa crônica durante a gravidez, considerando aspectos obstétricos e vasculares. Metodologia: A pesquisa foi realizada utilizando o checklist PRISMA, com busca nas bases de dados PubMed, Scielo e Web of Science. Foram utilizados cinco descritores: "varizes", "insuficiência venosa crônica", "gravidez", "cirurgia", e "saúde vascular". Os critérios de inclusão contemplaram artigos publicados nos últimos 10 anos, estudos que abordaram a cirurgia de varizes em gestantes, e pesquisas que incluíram resultados obstétricos e vasculares. Os critérios de exclusão incluíram revisões não sistemáticas, artigos que não focaram na população gestante, e estudos que não apresentaram dados relevantes sobre resultados cirúrgicos. Resultados: A revisão revelou que, embora a cirurgia de varizes durante a gravidez possa ser realizada com segurança em casos selecionados, é essencial considerar o estágio gestacional e a gravidade dos sintomas. A maioria dos estudos apontou para uma alta taxa de sucesso na redução dos sintomas e na prevenção de complicações, como trombose venosa profunda. Entretanto, os riscos potenciais, incluindo complicações anestésicas e efeitos adversos na gravidez, exigiram uma avaliação cuidadosa por parte da equipe médica. Conclusão: A abordagem cirúrgica de varizes em mulheres grávidas com insuficiência venosa crônica revelou-se uma intervenção que pode ser benéfica em determinadas situações, desde que realizada por profissionais experientes. A análise dos dados disponíveis ressaltou a importância de uma abordagem multidisciplinar, considerando tanto a saúde da mãe quanto a do feto.

Published: October 2024

Introdução: O lúpus eritematoso sistêmico (LES) é uma doença autoimune que provoca inflamação crônica, afetando múltiplos órgãos e frequentemente resultando em sequelas dermatológicas significativas, como lesões cutâneas, cicatrizes e alterações pigmentares. Essas sequelas não apenas comprometem a estética, mas também têm um impacto psicológico profundo na qualidade de vida dos pacientes. A cirurgia plástica reconstrutiva emergiu como uma intervenção potencialmente transformadora, promovendo a restauração da função e da aparência da pele. Embora haja uma crescente aceitação dessas intervenções, ainda existem lacunas no entendimento sobre os efeitos reais da cirurgia plástica reconstrutiva em pacientes com LES, especialmente sob a perspectiva dermatológica. Objetivo: Analisar o impacto da cirurgia plástica reconstrutiva em pacientes com sequelas de lúpus eritematoso sistêmico, abordando aspectos clínicos, psicológicos e sociais, bem como as melhores práticas e resultados associados. Metodologia: A metodologia seguiu o checklist PRISMA, realizando buscas nas bases de dados PubMed, Scielo e Web of Science, utilizando cinco descritores: "lúpus eritematoso sistêmico", "cirurgia plástica", "reconstrução", "sequelas" e "dermatologia". Os critérios de inclusão foram: artigos publicados nos últimos dez anos, estudos focados em cirurgia plástica reconstrutiva em pacientes com LES e pesquisas com avaliação de resultados clínicos. Os critérios de exclusão compreenderam: artigos não revisados por pares, estudos que não tratavam diretamente do LES e revisões ou comentários que não apresentavam dados originais. Resultados: Os resultados indicaram que a cirurgia plástica reconstrutiva proporcionou melhorias significativas na aparência estética, na autoestima e na qualidade de vida dos pacientes. Estudos revelaram que intervenções como enxertos de pele e técnicas de fechamento cirúrgico melhoraram as cicatrizes e as lesões, com um baixo índice de complicações. Além disso, a recuperação emocional dos pacientes foi frequentemente associada à normalização da imagem corporal, demonstrando a importância do tratamento cirúrgico no contexto dermatológico do LES. Conclusão: A cirurgia plástica reconstrutiva demonstrou ser uma alternativa eficaz para a recuperação estética e funcional em pacientes com sequelas de lúpus eritematoso sistêmico. Os achados ressaltaram não apenas os benefícios clínicos, mas também o impacto positivo na saúde mental e na qualidade de vida, enfatizando a relevância de uma abordagem multidisciplinar no tratamento desses pacientes.

Published: October 2024

A pneumonia adquirida na comunidade (PAC) é considerada a principal causa de mortalidade e morbidade com importante impacto clínico em todo o mundo.O tratamento inicial na atenção primária depende da avaliação clínica, enquanto os pacientes hospitalizados requerem combinações de pontuações clínicas, radiografia de tórax e vários ensaios microbiológicos e de biomarcadores. Essa abordagem diagnóstica abrangente, juntamente com amostragem adicional e testes moleculares em pacientes selecionados de alto risco, deve ser praticada. A terapia inadequada na PAC em pacientes hospitalizados prolonga a internação hospitalar e aumenta o custo e a mortalidade. Além disso, o surgimento de organismos multirresistentes representa desafios difíceis na decisão da terapia empírica e definitiva.

Closing the Plio-Pleistocene 13C cycle in the 405-kyr periodicity by isotopic signatures of geological sources
Authors: Köhler Peter
Published: October 2024

Abstract. The 13C cycle of the Plio-Pleistocene, as recorded in δ13C of benthic foraminifera, has power in periodicities related to the long eccentricity cycle of 405-kyr that is missing in corresponding climate records (e.g. δ18O). Using a global carbon cycle model I show that the long eccentricity in δ13C might have been caused by variations in the isotopic signature of geological sources, namely of the weathered carbonate rock (δ13Crock) or of volcanically released CO2 (δ13Cv). This closure of the 13C cycle in these peridicities also explains the offset in atmospheric δ13CO2 seen between the penultimate and the last glacial maximum. The necessary isotopic signatures in δ13Crock or δ13Cv which align my simulations with reconstructions of the 13C cycle on orbital timscales have most power in the obliquity band (41-kyr) suggesting that land ice dynamics are the ultimate cause for these suggested variations. Since the Asian monsoon as reconstructed from speleothems has also an obliquity-related component it is possible that these proposed changes in weathering are indeed, at least partly, connected to the monsoon as previously suggested. Alternatively, the suggested impact of land ice or sea level on volcanic activity might also be influential for the 13C cycle. This indirect influence of ice sheets on the long eccentricity cycle in δ13C implies that these processes might not have been responsible for the 405-kyr periodicity found in ice-free times of the pre-Pliocene parts of the Cenozoic.
Brief communication: Comprehensive Resilience to Typhoon Disasters: An Urban Assessment of 27 Cities in Seven Major River Basin, China

Published: October 2024

Abstract. The urban resilience based on typhoon disasters are often not assessed. In this communication, we reflect on this issue by analyzing 27 cities around seven major river basin in mainland China. In specific, we build a comprehensive indicator-based model, and adopted the entropy-weighting TOPSIS method. Results show that the Hai River Basin and the provincial capitals had a higher resilience to typhoon than others, while cities of the Pearl River Basin are weaker. In some regions with weaker economy, however, the resilience was relatively higher partly attributing to infrastructure, water conservation projects, and level of information disclosure. The analysis is helpful for agencies and professionals to enhance urban capability of resilience, and provides a realistic reference in response to typhoon threats.

Published: October 2024

Abstract. More frequent extreme rainfall events in a changing climate increase the risk of flash flooding that is affecting populations globally. However, the flood hazard modelling required to reduce disaster risk in populated urban environments is often limited by the availability of data required for model calibration and validation. In this study, we use a historical flood event captured by 5 m resolution satellite imagery to quantify the effects of flood model complexity and inform flood hazards under future climate scenarios in the West Bank, Palestine. Flooding in January 2013 affected over 12,500 people and large areas of cropland. Vegetation loss and damage during the event were captured using satellite imagery and a normalised difference vegetation index (NDVI), and used as a reference flood extent. The physics-based HEC-RAS flood model best reproduced this NDVI-derived inundation extent (F1 score = 0.76), although the FastFlood model was able to produce a similar inundation pattern (F1 score = 0.74) over 300 times faster. Simulated flood depths from both models were similar; FastFlood displayed a mean difference of -0.03 m and a mean absolute error of 0.51 m when compared to HEC-RAS. Climate analysis revealed that the January 2013 rainfall corresponded to a historical return period of between 1 in 5 and 1 in 10 years. In comparison, a 1 in 100-year rainfall event (RX1day (maximum 1-day precipitation) of 148 mm) based on historical data (1985–2014) could increase by almost 40 % (to 205 mm) in the mid-future (2041–2060), which could cause 23 % (4 km2) greater inundation compared to the 2013 event. Although the patterns of future precipitation in the region are uncertain, our flood hazard maps can support urban planning and infrastructure development to manage storm water runoff, particularly where ephemeral channels, or wadis, intersect the road network.
Two-years of stratospheric chemistry perturbations from the 2019/2020 Australian wildfire smoke

Published: October 2024

Abstract. The very large pyrocumulonimbus events that occurred during the Australian summer of 2019/2020 caused extremely unusual partitioning of stratospheric chlorine in Southern Hemisphere midlatitudes and Antarctic regions. This was likely caused by enhanced HCl solubility in organic species that increased heterogeneous chemistry. Here, we show that observed HCl and ClONO2 values remain outside the pre-wildfire satellite range since 2005 in both the Southern Hemisphere midlatitude and Antarctic regions in 2021. Through model simulations, we replicate this multi-year prolonged chemical perturbation, in good agreement with observations. This was achieved by calculating HCl solubility in mixed wildfire and sulfate aerosols consistent with assumptions of 1) liquid-liquid phase separation and 2) linear dependence on organic and sulfate composition. The model simulations also suggest that the Australian pyrocumulonimbus organic aerosols contributed to low midlatitude ozone values in 2021. A marked photochemically controlled seasonality of the chemical perturbations and ozone depletion is also observed and simulated, and its underlying chemical drivers are identified. This work highlights that lower concentrations of smoke still had profound effects on stratospheric heterogeneous chemistry more than a year after the 2019/2020 wildfire event.
Trends and seasonal signals in Atlantic feature-based jet stream characteristics and in weather types
Authors: Banderier Hugo , Tuel Alexandre , Woollings Tim , Martius Olivia
Published: October 2024

Abstract. Recent studies have highlighted the link between upper-level jet dynamics, especially the persistence of certain jet configurations, and extreme summer weather in Europe. The weaker and more variable nature of the jets in summer makes it difficult to apply the tools developed to study them in winter, at least not without modifications. Here, to further investigate the link between jets and persistent summer weather, we present two complementary approaches to characterize the jet dynamics in the North Atlantic sector and use them primarily on the summer circulation. First, we apply the self-organizing map (SOM) clustering algorithm to create a 2D distance-preserving discrete feature space to the tropopause-level wind field over the North Atlantic. The dynamics of the tropopause-level wind can then be described by the time series of visited SOM clusters, in which a long stay in a given cluster relates to a persistent state and a rapid transition between clusters that are far apart relates to a sudden considerable shift in the configuration of upper-level flow. Second, we adapt and apply a jet axis detection and tracking algorithm to extract individual jets and classify them in the canonical categories of eddy-driven and subtropical jets (EDJ and STJ, respectively). Then, we compute a wide range of jet indices on each jet to provide easily interpretable scalar time series representing upper-tropospheric dynamics. This work will exclusively focus on the characterization of historical trends, seasonal cycles, and other statistical properties of the jet stream dynamics, while ongoing and future work will use the tools presented here and apply them to the study of connections between jet dynamics and extreme weather. The SOM allows the identification of specific jet configurations, each one representative of a large number of days in historical time series, whose frequency or persistence had increased or decreased in the last decades. Detecting and categorizing jets adds a layer of interpretability and precision to previously and newly defined jet properties, allowing for a finer characterization of their trends and seasonal signals. Detecting jets on flattened pressure levels instead the 2PVU surface is more robust in summer, and finding wind-direction-aligned subsets of 0-contours in a wind shear field is a fast and robust way to extract jet features. Using the SOM, we highlight a trend towards more negative NAO, and isolate predictable and/or persistent circulation patterns. Using properties of the jet features, we confirm that jets get faster and narrower in winter, but not so clearly in summer, and find no significant trend in jet latitude. Finally, both methods agree on a sudden flow transition in June.

Published: October 2024

Abstract. In order to design a self-adaptive tracked mechanism that can passively adjust according to the height of different obstacles to improve its obstacle-crossing performance, this paper proposes a linkage-type self-adaptive deformable tracked mechanism. The mechanism based on the planar six-bar mechanism is proposed, and its motion modes and obstacle-crossing capabilities are analyzed. Firstly, based on the characteristics of self-adaptive deformation and the planar six-bar mechanism, a deformable single-degree-of-freedom (DOF) multi-loop mechanism is designed by limiting the DOF and adjusting the link lengths, and subsequently, a linkage-type self-adaptive deformable tracked mechanism module is designed according to the multi-loop mechanism. Secondly, the movement characteristics of the deformable tracked mechanism module are analyzed, and it is obtained that the tracked mechanism has two modes of movement: forward and reverse. These modes include deformable tracked-type obstacle crossing and rocker-arm-type obstacle crossing, respectively. Additionally, it is also obtained that this mechanism is capable of climbing up and descending down slopes. Finally, a prototype model is designed for experimental verification to verify the correctness of the theoretical analysis of the linkage-type self-adaptive deformable tracked mechanism and the feasibility of the obstacle-crossing modes. The results indicate that the linkage-type self-adaptive deformable tracked mechanism is capable of various obstacle-crossing modes, including both forward and reverse movements. These modes encompass the traditional tracked type, the deformable tracked type, and the rocker-arm type, as well as the ability to climb up and descend down slopes. This type of mechanism demonstrates excellent terrain adaptability and is capable of overcoming obstacles, allowing it to traverse some soft and rugged terrain. Consequently, it holds certain application potential.
A CONSTITUCIONALIZAÇÃO DO MINISTÉRIO PÚBLICO E A ATUAÇÃO MINISTERIAL DEMOCRÁTICA E INIBITÓRIA

Published: October 2024

A constitucionalização do direito exige que qualquer agressão aos mandamentos constitucionais incite imediata atuação dos órgãos legitimados em prol da proteção ao regime democrático e dos direitos fundamentais. A partir desse pressuposto, o Ministério Público imbui-se da defesa da ordem jurídica mediante ação inibitória e preventiva junto às autoridades e entes lesionados e lesionadores. Assim, pretende-se analisar a natureza jurídica das recomendações ministeriais, enquanto forma de atuação ministerial extrajudicial, e compreender seus limites frente às funções do Ministério Público constitucionalizado. Ademais, busca-se delimitar as consequências do descumprimento das recomendações ministeriais e seus corolários. Constata-se, ainda, e ao fim, a importância constitucional e vital do Ministério Público para garantia da justiça e do regime republicano. Para isso, adota-se investigação de caráter jurídico-dogmático e o método hipotético-dedutivo junto aos marcos bibliográficos adotados.
Estabilidades no saneamento e na organização do processo
Authors: Kochenborger Scarparo Eduardo , Magni Berthier Fernanda
Published: October 2024

A decisão de saneamento e organização do processo possui uma dupla função, retrospectiva e prospectiva, na medida em que controla a sua regularidade ao mesmo tempo em que delimita os atos processuais pendentes de realização. Trata-se de disposição trazida pelo Código de Processo Civil de 2015 que determinou a concentração das funções saneadora e organizadora do juiz em um único momento processual, inovando especialmente no que tange à atividade ordenadora, a qual era frequentemente negligenciada na prática forense sob a égide da legislação anterior. Uma grande fonte de dúvidas diz respeito à previsão do parágrafo primeiro, do art. 357, do CPC/2015, o qual dispõe acerca da estabilidade dessa decisão após o transcurso do prazo para que as partes peçam esclarecimentos ou solicitem ajustes. Tendo em vista a ausência de definição legal relativamente à extensão dessa estabilidade, o presente estudo tem por objetivo, especificamente, analisar a ocorrência de preclusão em relação às questões resolvidas na decisão de saneamento e organização do processo, obstando a sua rediscussão posterior e trazendo maior segurança e efetividade à demanda. Para tanto, utilizou-se do método dedutivo, sobretudo a partir da realização de revisão analítica da doutrina e da jurisprudência acerca da temática. Como conclusão, partindo-se da premissa de que há funções e propósitos diferenciados entre as questões de saneamento e as de organização do processo, propõe-se a existência de um esquema de estabilidades para cada tipo de matéria apreciada. Nesse sentido, em relação às questões de saneamento, defende-se a ocorrência de preclusão sem maiores dificuldades. De outra banda, quanto às questões de organização, reconhece-se a necessidade de haver uma maior flexibilidade na estabilização, especialmente no que tange às matérias de produção probatória. Assim, evidencia-se a importância de se considerar a convivência de diferentes modelos de estabilidade sobre uma mesma decisão, de modo a efetivar a busca por uma adequada prestação jurisdicional em observância aos diferentes direitos processuais fundamentais.
Scientific Interests and Technological Innovation in Byzantium: Interdisciplinary Perspectives

Published: October 2024

This editorial begins by surveying the status of Byzantine science and technology as a field integral to the history of science as an academic discipline. After addressing the marginalization of Byzantine science and technology until quite recently, the editorial then proceeds to show that the origins of this field are not recent. Building on the trailblazers of the early twentieth century, a plethora of scholars have already contributed to the emergence of the field as a respectable and consequential pursuit. Much more should be done, however, and the articles here summarised inaugurate further avenues of research that, hopefully, will contribute to the recognition of this field by historians of science and scholars of Byzantium alike.

Published: October 2024

Data analysis is essential for fault identification and detection in smart grids in order to maintain grid monitoring. Many DL algorithms have been developed recently for data analysis applications related to smart grids. To resolve these challenges, the study suggests a Deep Neural Network (DNN) for data-driven fault location detection and type of fault classification by exploiting the Modified Sand Cat Swarm Optimization (MSCSO) optimization. Here, the DNN is used to diagnose the faults and determine the position of the sites. Numerous synthetic field data sets derived from simulated models of different transmission line types are used for training and testing. The position and type of faults are predicted by the DNN classifier based on the fault signal features, in which the DNN weights are ideally tuned using a novel MSCSO optimization method that is the improved concept of Sand Cat Swarm Optimization (SCSO). Lastly, MATLAB/Simulink is used to implement the suggested DNN-based method for fault classification and its localization in transmission line. An intellectual IEEE 6-node network model is utilized to confirm the efficacy and reliability of these methods. The outcomes demonstrated its effectiveness in giving the system operator precise and detailed analytics for fault identification.

Published: October 2024

This study presents the design, construction, and operational details of an experimental recirculating water channel dedicated to the assessment of hydrokinetic turbines, including a propeller-type turbine and a H-Darrieus turbine, since it offers a controlled testing environment. The recirculating water channel had overall dimensions of 5 m in length, 0.35 m in width, and 0.5 m in depth, it allows for the replication of various water flow conditions and permits a maximum achievable flow velocity of 0.6 m/s, which closely resembles real-world scenarios. Afterwards, a propeller- type turbine and a H-Darrieus turbine underwent characterization within the channel, and a performance curve constructed through the coefficient versus the blade tip speed ratio (TSR) revealed a peak efficiency of 0.2129 at a TSR of 2.952 for the propeller turbine, and a higher peak efficiency of 0.3076 at a TSR of 0.38 for the H-Darrieus turbine. The versatility of this experimental setup makes it a valuable platform for in-depth performance studies of hydrokinetic turbines. This water channel and its systematic characterization process represent a vital resource for conducting efficiency and behavior analyses across a wide range of operational parameters related to hydrokinetic turbine technologies.
An Early Warning Method for Volleyball Players with Human Bioelectric Energy
Authors: Pang Jundi
Published: October 2024

Bioelectric energy is a weak electric current generated by the human body itself, and the change in its value can indicate human injury, which can be used as a competitive physical injury judgment information. However, in the past, bioelectric energy measurement was mainly based on the standard voltage of 220 V, and it was not possible to conduct follow-up tests, so the scope of application was limited.

This paper explores the application of the XGBoost machine learning model for forecasting the hourly thermal demand in District Heating Systems, aligning with the European Union’s ambitious sustainability targets as outlined in the Renewable Energy Directive (RED) and the Energy Efficiency Directive (EED). Accurate forecasts of thermal demand are crucial for enhancing the efficiency of district heating systems through the integration of renewable energy sources and the adoption of waste heat recovery, thereby contributing significantly to achieving climate neutrality by the year 2050. This study presents a dual approach to forecasting: at the individual building level, and at an aggregated level by considering the average characteristics of the served building stock. Through a comprehensive case study of the Turin district heating system (Italy), which comprises hourly data from approximately 200 heat exchange substations across nine heating seasons, this research evaluates the comparative effectiveness of different forecasting approaches in terms of prediction accuracy and computational efficiency. The findings aim to guide district heating operators and planners in selecting the most suitable forecasting approach based on available input information, desired accuracy, and computational constraints, contributing to the strategic planning and development of sustainable and efficient district heating systems.

Published: October 2024

This paper presents the investigation carried out on the portability and compatibility of a model in different simulation software. The offer of simulation software for power system simulation is wide, with each program having its own modelling interface and its own methods of model development. The lack of a widespread standard for portability between applications implies that the same organisation needs to carry out studies on different applications, requiring the development of a model of the same element or system for each application. This study presents an example of the integration of an inverter model in DigSilent, PSCAD and Simulink by means of the Multilink tool. Throughout the article, the differences found when performing the integration and the same simulation scenario in these three simulation tools are listed. It concludes with a comparison of the results obtained from an electromagnetic transients (EMT) simulation in the three simulation software. The results show a greater similarity between PSCAD and Simulink, with respect to the results obtained in DigSilent.
