Authors: Francelin Maria Cristina , Amaral Fabiana , Campos Ivana , Figueiredo Luana , Rocha Monica , Pereira Pedro , Zuffi Simone , Souza Tania
Published: May 2024

Introdução: A profilaxia pós-exposição (PEP) é uma das estratégias ofertadas nas quatro Unidades de Pronto Atendimento (UPAs) durante 24 horas como parte da cascata de cuidado à prevenção das infecções sexualmente transmissíveis (IST). Foi implantada uma ficha de notificação que fornece aos órgãos competentes as informações do evento. A partir dessa notificação, poderão ser tomadas medidas de promoção e proteção. Há 1.816 notificações. Objetivo: Descrever o perfil de usuários que procuraram a PEP no município de Ribeirão Preto, São Paulo. Métodos: Estudo transversal retrospectivo, com uso de dados secundários de usuários. No estudo foram incluídos todos os usuários que iniciaram PEP no período de dezembro de 2021 a junho de 2022. As variáveis qualitativas foram descritas em percentual, e as variáveis quantitativas, com medidas de tendência central (média) e dispersão (desvio padrão). Resultados: Dos 555 usuários, foram mais frequentes adultos jovens, com média de idade de 31,8 anos, desvio padrão 9,6 anos, homens (71,9%), raça/cor da pele branca (70,3%) e ensino universitário completo (39,5%). A exposição sexual (79,1%) foi mais frequente. Conclusão: Nesse contexto, a PEP se apresenta como último recurso para evitar a infecção pelo HIV, após as demais medidas conhecidas terem falhado. O acesso à PEP é dificultado pelo desconhecimento sobre a profilaxia e constitui uma grande barreira. O uso de PEP não foi homogêneo entre os grupos avaliados, com baixa frequência de pessoas transgênero e profissionais do sexo. A alta escolaridade dos usuários de PEP pode ser um indicativo de acesso à informação, sugerindo que pessoas com menos anos de escolaridade se encontram em situação de maior vulnerabilidade. Assim, faz-se necessário repensar ações e políticas de prevenção a segmentos mais vulneráveis da sociedade para a prevenção das IST. É importante ampliar a noção de risco , identificar fatores sociais e acesso a serviços públicos por populações específicas.

Published: May 2024

The purpose of this study was to validate the Saudi version of the Mathematics Confidence Scale among undergraduate students. To achieve this, a sample of 1324 undergraduate students from various schools across Saudi Arabia was selected. The participants' demographics, including gender, grade, and type of school, were considered in order to ensure a representative sample. The participants were given the Mathematics Confidence Scale questionnaire, which consisted of 30 statements related to their confidence in mathematical abilities. Each statement was rated on a Likert scale ranging from 1 (strongly disagree) to 5 (strongly agree). The Likert scale was chosen to measure participants' responses because it allows for a more nuanced understanding of their levels of confidence in mathematics. The results indicated That the Saudi Version of the Mathematics Confidence Scale is reliable and valid. This suggests that the scale can be used effectively to assess the confidence levels of undergraduate students in mathematics in Saudi Arabia. Further research should be conducted to investigate the psychometric properties of the Saudi Version of the Mathematics Confidence Scale using IRT models. IRT models can provide more in-depth analysis of item response patterns and help identify specific areas where students may be lacking confidence in mathematics. They can also help determine whether certain items on the scale are functioning as intended and provide insights for improving the scale's overall validity and reliability

Objetivos: Analisar o impacto da pandemia da síndrome respiratória aguda grave do coronavírus 2 (SARS-CoV-2) nas doações de tecidos oculares quanto às perdas de oportunidade de potenciais doadores devido à suspensão das captações e às mudanças nos critérios de elegibilidade, nas taxas de elegibilidade hospitalar de doadores e causas de não doação. Métodos: Foram analisados dados de pacientes falecidos em parada cardiorrespiratória (PCR) em um hospital universitário brasileiro em 2020. Compararamse o número de doações efetivadas, o número de óbitos potencialmente elegíveis para doação e as causas de não doação nos três períodos de 2020: período 1, pré-pandemia (1 de janeiro a 18 de março de 2020), período 2, com suspensão de doações em PCR (19 de março a 19 de setembro de 2020), e período 3, de captações com triagem epidemiológica para SARS-CoV-2 e redução da faixa etária de doadores até 65 anos (20 de setembro a 31 de dezembro de 2020). Resultados: Houve 710 óbitos por morte circulatória em 2020. A taxa de elegibilidade hospitalar foi de 5,7% em 140 óbitos no período 1, 11,9% de 395 pacientes durante a suspensão da captação no período 2 e 3,4% de 175 pacientes durante as restrições da faixa etária e triagem para doença do coronavírus 2019 (COVID-19) (p = 0,004). Os 47 pacientes falecidos no período 2 representaram perda de oportunidade de doação devido à suspensão das captações e 13 (7,6%) dos 175 pacientes no período 3 não foram elegíveis devido à redução da faixa etária. Dentre os elegíveis sem contraindicação clínica, 81% dos 75 pacientes tiveram limitação na oferta de doação devido às restrições da pandemia. Apenas um paciente foi considerado inelegível para doação devido à triagem clínico-epidemiológica para SARSCoV-2. As infecções graves foram a principal causa de não doação em 50,7, 48,1 e 47,4% dos óbitos nos três períodos (p = 0,615). Conclusão: A pandemia de SARS-CoV-2 afetou significativamente a captação de tecidos oculares para transplantes devido às medidas restritivas implementadas por motivos de segurança, resultando na perda de oportunidade de doação para 81% das famílias. As taxas de elegibilidade de potenciais doadores foram reduzidas significativamente pela restrição de faixa etária. As infecções graves foram a principal causa de não doação de tecidos oculares, porém, neste estudo, não houve aumento significativo durante o período pandêmico estudado.

Authors: Belkacem Mounia , Benmebarek Sadok , Saifi Insaf
Published: May 2024

The bearing capacity of axially loaded embedded foundations has been widely studied using analytical and numerical methods. However, there are many discrepancies in the literature results regarding the bearing capacity factors and depth factors of circular embedded footings proposed by different authors. Terzaghi's hypothesis has been used to assess the bearing capacity of shallow foundations and several analytical solutions have been proposed for computing bearing capacity factors, even though a superposition of individual contributions may lead to some error in the computed bearing capacity.  This assumption has sometimes been criticized as being more conservative. This article aims to study two problems; The first part is focuses on the numerical evaluation of the superposition hypothesis in the calculation of the bearing capacity for rough circular foundations embedded in sand. In this section, the bearing capacity factors contributing to the conventional solution have been evaluated and superposition errors are indicated and compared with those found  by different authors. The latter part of the work is devoted to studying the depth effect on the estimation of the bearing capacity of a rough circular footing embedded in the sand considering presence of an overload adjacent. For both analyses, the finite-difference code Flac2d (FLAC 2007) was used to reach the bearing capacity for embedded circular footings, the ground friction angles are between 25° and 40° and a depth ratio Df/D varies from 0.1 to 2. The calculation results are presented in tables and graphs and compared to previously published results available in the literature.

Authors: Mahammedi Abdelkader , Abderrahmane Amari , Medjahed Driss Meddah , Medjadji Nassira
Published: May 2024

In this work, we look at the mixing capabilities of a static Y-micromixer, which achieves very good mixing quality when compared to other recently proposed micromixers in terms of mixing quality. We propose to change both the quantity and arrangement of element pairs. The 3D momentum equations, continuity equation, and species transport equations have all been solved numerically at moderate Reynolds numbers using the CFD Fluent tool. The lengthening of the Y-shape is determined by the quantity of pairings. A comprehensive analysis was conducted by varying the number and position of element pairs across a broad spectrum of Reynolds numbers, ranging from 1 to 400. The numerical simulations examined the acquired outcomes by displaying the contours of mass fraction, vorticity, mixing performance and pressure losses in various planes. The chosen geometry, consisting of 4 pairs of components, has exceptional mixing capabilities. The mixing index surpasses 47% at Re = 1 and achieves a maximum of 99% at Re = 400. Furthermore, it exhibits a reduced pressure drop in comparison to other recently examined geometries. Hence, the chosen micromixer demonstrates excellent mixing capabilities at moderate Reynolds numbers, rendering it suited for improving fluid mixing in diverse microfluidics systems.

Authors: Sousa Alberto Camarão de , Vasconcelos Arthur Benites , Reis Dayene Kalinne de Sousa Santos dos
Published: May 2024

Objetivo: contribuir, para com Guideline de hematologia e neurologia para diagnósticos da anemia megaloblástica e depressão. Metodologia: um estudo sobre a possível correlação entre a anemia macrocítica, megaloblástica com a depressão realizado de forme retrospectiva e qualitativa com base em conteúdo de livros da biblioteca da UNIFAMAZ e artigos científicos da PUBMED e Medline e SciELO. Discussão: segundo “Failace e Fernandes, 2009”, doenças autoimunes, gastrectomias, uso pertinente de medicamentos inibidores da bomba de próton, doenças ileal, doença de Imerslund-Grãsbeck, todas essas doenças e fatores podem causar a anemia megaloblástica pelo fato de o estômago ser o principal órgão afetado nesses quadros, e sabe-se que as células parietais da mucosa gástrica produzem o fator intrínseco capaz de se ligar com a vitamina b12 e ser absorvido nos receptores localizados na porção final do intestino delgado (íleo). “Lorenzi, 2006” diz que a anemia não significa uma doença em si, ela representa um achado clinico-laboratorial, onde necessita uma investigação criteriosa para saber a sua causa para poder iniciar o tratamento, visto que as alterações que repercutem em diminuições ou mudanças estruturais das hemácias podem estar relacionadas com doenças medulares e aplásicas. “Lent, 2005” afirma que os neurônios centrais, necessitam de uma estrutura lipídica capaz de aumentar sua transmitância que gira em torno de 100m/s, a bainha de mielina. Conclusão: a interação fisiopatogênica da anemia macrocítica megaloblástica com a depressão, de modo que a vitamina b12 atue na formação das hemácias e da bainha de mielina. Contudo, a importância do diagnóstico laboratorial para a anemia, repercute em um artefato satisfatório para um possível quadro depressivo já que ambas podem estar relacionadas com a mesma etiologia.

Published: May 2024

O mercúrio é um metal pesado reconhecido por seus riscos significativos à saúde humana e ao meio ambiente, especialmente quando se transforma em metilmercúrio, uma forma altamente tóxica, capaz de causar danos neurológicos, cardiovasculares e reprodutivos em animais e humanos, tornando essencial o monitoramento das concentrações desse metal, especialmente em pisciculturas, considerando seus impactos adversos na contaminação de peixes e consequentemente à saúde humana ao consumi-los. Portanto, o objetivo deste artigo foi avaliar a concentração de mercúrio em 12 pisciculturas no Estado de Mato Grosso, Brasil. Para isso, foram coletadas amostras de sedimentos, solos e vegetação dos tanques de criação de peixes e nas áreas adjacentes (aproximadamente 15 metros dos tanques). Além disso, tecidos de músculo, cérebro, fígado e nadadeiras do peixe híbrido tambatinga foram coletadas. Todas as amostras foram analisadas seguindo o método US EPA 7473, para as matrizes e utilizando o aparelho DMA-80. De acordo com os resultados, as análises revelaram que as concentrações de mercúrio estavam abaixo dos limites estabelecidos pela legislação brasileira, sugerindo conformidade com os padrões regulatórios. Entretanto, é importante salientar a ausência de determinação pela Resolução do Conselho Nacional do Meio Ambiente (CONAMA) sobre os limites aceitáveis de mercúrio na vegetação de áreas rurais, o que configura uma lacuna normativa que demanda atenção. Assim como é crucial enfatizar a persistente toxicidade do mercúrio e a necessidade de monitoramento contínuo, devido ao seu potencial impacto na saúde humana e ambiental a longo prazo. Portanto, a vigilância constante é fundamental para garantir a segurança alimentar e a preservação dos ecossistemas aquáticos.

Authors: SHAMIM S , ABDULLAH M , SHAIR H , AHMAD J , FAROOQ MO , AJMAL S
Published: May 2024

Climate change is increasing stress on agricultural production, notably in developing nations where crop yields are critically impacted. Swift changes in climate conditions directly diminish wheat yields and adversely influence key grain constituents such as starch, fibre, protein, amino acids, and essential nutrients. The studies were conducted for six years, from 2017-18 to 2022-23, to understand the impact of changing climate on wheat grain composition and quality. The results indicated that November is the best month for sowing wheat. The post-anthesis drought or less water availability helps the plants accumulate more protein and gluten contents, and starch contents decrease. The quality of the grain, however, is more significantly influenced by the variety of wheat, the type of environmental stress, and the duration and severity of exposure. Faisalabad 08 had the highest protein and gluten contents, while Galaxy 13 had the highest starch contents in D2. Galaxy 13 indicated the highest value of test weight and 1000-grain weight in November.

Published: May 2024

Background: The widespread administration of quinolones may have led to an increase in bacterial resistance development. Objective: To synthesize and characterize manganese oxide nanoparticles (MnO2NPs) and evaluate their effects on the viability and biofilm formation of quinolone-resistant gram-positive and negative pathogenic bacteria. Methods: We prepared MnO2NPs using the photo-irradiation method and recorded their characteristics using XRD, TEM, and SEM. Staphylococcus aureus, Streptococcus pneumonia, Escherichia coli, Klebsiella pneumonia, and Pseudomonas aeruginosa were collected from the wastewater of Baghdad hospitals during the period from July 3rd to July 14th, 2023. We used the VITEK2 system to confirm and identify all of the isolates. We conducted biofilm formation and antibiotic susceptibility tests using nalidixic acid, ciprofloxacin, norfloxacin, aztreonam, levofloxacin, and ofloxacin, and also detected the qnrA and qnrB genes. Finally, we evaluated the effects of the prepared nanoparticles on the viability and biofilm formation of bacterial isolates. Results: MnO2NPs characterizations showed a diffraction peak at 2θ values with 21 nm average sizes; qnrA and qnrB genes were found in three and four isolates, respectively; and significant effects of MnO2NPs against viability and biofilm formation were recorded. Conclusions: The synthesized nanoparticles have antibacterial and anti-biofilm activities against a variety of bacteria possessing qnr genes. Even multi-resistant bacterial isolates have the potential to be strong antimicrobial agents against these pathogens.

Information management and optimization methods in architectural construction drawings: A case study of the "Coconut forest settlement" in Hainan
Authors: Zheng Ziang
Published: May 2024

This paper investigates information management and optimization methods within architectural construction drawings, using the Coconut Forest Settlement project in Hainan as a case study. Five key categories of methods are explored: clarification, structuring, standardization, precision, and lightweight. These methods address issues such as the lack of case-based analysis, the need for better information management, and the reduction of information redundancy. By classifying and discussing these strategies, the study highlights the enduring relevance of construction drawings in the digital age. Furthermore, it envisions the transferability of these methods to different contexts due to their emphasis on logical commonalities and the ever-present need for efficient information management. Practical examples from other fields, such as Revit, Rhino, and Grasshopper, are cited to demonstrate the potential applicability of these methods beyond traditional construction drawings. This paper contributes to the enhancement of information management in architectural design, fostering innovation and improved efficiency across various applications.
Recent advances in single-phase rectification methods
Authors: Zhai Shixian
Published: May 2024

With the increasing number of population, people are increasingly dependent on electricity. In recent years, more and more public transportations like bus, taxi take the mode of pure electric. The function of rectifier is to transform the AC current into DC current, which is a significant research direction in electrical industry, especially in power electronic technology. In our nation, the national grid supplies 220V 50Hz AC to residence, it is a voltage pattern that varies periodically. Due to the lower loss of power during long-distance transmission, it has become the basic mode of power transmission and supply in the world. In usual production and our daily life, we frequently need DC (such as: mobile phones, flashlights, computers, charging piles for electric vehicles, etc.), so rectifier has become a heated research part. At present, more and more researches are based on power electronic technology, design all kinds of rectifier circuit by using the between conductor and insulator property of semiconductors. This essay provides an overview of single-phase rectifier circuits (including half-wave rectifier, full-wave rectifier, and bridge rectifier) and passive power factor correction.
Current research on exoskeletal lower limb rehabilitation robots
Authors: Wei Zhihao
Published: May 2024

Stroke is characterized by a high incidence rate, and walking is one of the essential human functions. Lower limb rehabilitation robots can offer safe and effective walking training to patients with walking impairments caused by conditions such as neural injuries, aiding in their recovery or assisting in walking. For the needs of patients themselves, restoring their physical state and motor function as much as possible is the primary purpose of rehabilitation, and rehabilitation efficiency is an important factor affecting the quality of life of patients after surgery. Research on exoskeleton robots varies both domestically and internationally, each with its own unique characteristics and features. This paper outlines the design of lower limb rehabilitation robots based on gait analysis and control methods. It also provides an overview of the current state of research on lower limb exoskeleton robots in terms of degrees of freedom, actuation methods, and clinical applications. Furthermore, it offers insights into future directions for research on lower limb exoskeleton robots.
Diagnosis and Management of Periprosthetic Joint Infections After Total Ankle Arthroplasty
Authors: Atesok Kivanc , Scott Daniel J. , Hurwitz Shepard , Gross Christopher E.
Published: May 2024

Periprosthetic joint infection (PJI) after total ankle arthroplasty (TAA) is a dreaded complication that may lead to catastrophic outcomes. Risk factors include a history of surgery on the operated ankle, low preoperative function scores, diabetes, extended surgical time, and postoperative wound-healing problems. Clinical presentation varies and may include increasing ankle pain and swelling, high temperature, local erythema, wound drainage, and dehiscence. The initial diagnostic evaluation should include plain radiographs, erythrocyte sedimentation rate, C-reactive protein levels, and leukocyte count. In suspected cases with elevated erythrocyte sedimentation rate and C-reactive protein, aspiration of the ankle joint for synovial fluid analysis, Gram staining, and culture should be performed. Antibiotic therapy should be based on the pathogen identified, and the surgical strategy should be determined based on the time lines of PJI. Early PJI can be treated with irrigation and débridement with polyethylene exchange. The surgical treatment of choice for late PJI is two-stage revision arthroplasty, which includes removal of the implant, insertion of an antibiotic spacer, and reimplantation of a TAA. In certain chronic PJI cases, permanent articulating antibiotic spacers can be left in place or an ankle arthrodesis can be performed. Below-knee amputation is considered as the final option after limb-sparing procedures have failed.

INTRODUCCIÓN. La tiamina es un fármaco indicado en el tratamiento y prevención de la encefalopatía de Wernicke, que debe administrarse en caso de alcoholismo crónico o de malnutrición. Se evaluó el uso de la tiamina durante la asistencia de pacientes con intoxicación alcohólica aguda y si éste era adecuado. MATERIAL Y MÉTODOS. Estudio retrospectivo de todos los pacientes atendidos en el servicio de urgencias de un hospital universitario por intoxicación alcohólica aguda durante el año 2021. Se recogieron datos de filiación, forma de acceso a urgencias, lugar e intención de la intoxicación, antecedentes psiquiátricos y de intoxicaciones previas, clínica y consumo concomitante de otros tóxicos. Los pacientes se dividieron en dos grupos según se había administrado tiamina o no, se determinó si la indicación era correcta y se evaluó la presencia de factores asociados a su administración. RESULTADOS. Se atendieron 341 pacientes. Se administró tiamina en 98 casos (28,7%). En 78 (79,6%) estaba correctamente indicada. Los pacientes a los que se les administró eran de mayor edad [42,9 (13,6) vs 34,1 (15,3) años; p < 0,001] y preferentemente varones (36,6% vs 15,2%; p < 0,001). Una puntuación inferior a 9 en la escala de Glasgow se asoció al uso de tiamina (52,9% vs 26,8%; p = 0,027), así como la existencia de intoxicaciones previas (79,6% vs 44%, p < 0,001) y de antecedentes psiquiátricos (29,6% vs 18,5%; p = 0,025).

A porous structure is widely used in additive manufacturing of orthopedic implants to reduce the stiffness mismatch between the implant and the bone. The development and improvement of porous structures for orthopedic implants is still a major challenge. It is essential to study mechanical properties of different porous structures and their relation to the deformation mechanism. In this paper, the relation between the deformation mechanism and the mechanical properties of Ti6Al4V triply periodic minimal surface (TPMS) structures, such as stretchingdominated IWP and bending-dominated gyroid structures, are investigated using the finite element analysis for uniform and density gradient scaffolds. The method for designing network-based and sheet-based TPMS structures is presented. The numerical results show that failure in the stretching-dominated structure (IWP) starts with buckling of the vertical struts, whereas failure in the bending-dominated structure (gyroid) occurs with the formation of the 45° shear band. The gyroid structure shows a higher shear modulus than the IWP structure. The numerical results exhibit good agreement with the previous experimental data for uniform and density gradient structures. Finally, the effect of the void defect on the elastic and shear moduli is evaluated. The results indicate that the elastic modulus of the bending-dominated structure shows a greater reduction in the presence of void defects than that of the stretching-dominated structure, and the shear modulus of the stretching-dominated structure is more sensitive to void defects than that of the bending-dominated structure.
