Authors: Brito Emerson , Pinheiro Ben Hur Graboski , Paula Thayane Fraga de , Basgalupp Suelen Porto , Dorneles Thayane
Published: May 2024

Introdução: O tabagismo segue sendo um problema de saúde pública em razão de suas altas taxas associadas à morbimortalidade. É mais frequentemente observado em populações específicas como jovens e homens que fazem sexo com homens (HSH). Estudos populacionais que avaliam o tabagismo na população LGBTQIAP+ brasileira são limitados. Objetivo: Avaliar a prevalência e fatores associados do uso de tabaco em homens gays e bissexuais vivendo com e sem HIV. Métodos: Estudo transversal realizado entre setembro e outubro de 2020, incluindo 655 participantes. Gays, lésbicas, bissexuais e outras minorias de gênero maiores de 18 anos foram convidados a responder a um questionário semiestruturado de forma on-line. A pesquisa foi divulgada por meio das redes sociais e por representantes da população LGBTQIAP+ no Brasil. Utilizaram-se frequência absoluta e teste de χ2 para as análises. Considerou-se um nível de significância de 95%. Resultados: A amostra foi composta de 421 participantes homens que se autodeclararam gays (91%) e bissexuais (9%). Entre os participantes, 14,2% referiram estar vivendo com HIV. O consumo de tabaco foi identificado em 16,7% dos indivíduos; entre os participantes que viviam com HIV, a prevalência era de 28,1%, e nos participantes que não viviam com HIV, 14,8% (p=0,01). A média de cigarros no último ano foi de 9 cigarros/dia. Entre os participantes que viviam com HIV, a média foi de 13 cigarros/dia, e entre os participantes que não viviam com HIV, 7 cigarros/dia (p=0,02). Conclusão: É necessário identificar a prevalência de tabagismo em populações específicas. Homens gays e bissexuais que vivem com HIV apresentaram taxas altas de prevalência nesses achados, fator que pode indicar uma necessidade de atenção dos serviços de saúde.
Perfil epidemiológico das mães de filhos com sífilis congênita no estado de Santa Catarina em 2021
Authors: Silva Leonora Ramlow Leodoro da , Silva João Antônio Ramlow Leodoro da
Published: May 2024

Introdução: A sífilis congênita representa uma grande preocupação para a saúde pública, caracterizando uma doença de notificação compulsória em todo o Brasil. Em 2020, foram notificados, no Sistema de Informação de Agravos de Notificação (SINAN), 22.065 casos de sífilis congênita (7,7 casos a cada 1.000 nascidos vivos). O conhecimento do perfil das mães com filhos afetados pela sífilis congênita é essencial para o planejamento de ações em saúde. Objetivo: Analisar o perfil epidemiológico das mães em notificações de sífilis congênita em 2021, em Santa Catarina. Métodos: Estudo transversal e observacional realizado a partir de dados coletados no site do Departamento de Informática do Sistema Único de Saúde (DATASUS) referentes a casos de sífilis congênita em 2021, no estado de Santa Catarina. Resultados: Percebeu-se que, no período, 17% dos casos dos nascidos vivos com sífilis congênita tinham mães na faixa dos 15–19 anos; 23%, dos 20–24 anos; e 32%, dos 25–29 anos. Quanto à escolaridade, foi detectada maior prevalência dessas mães com ensino médio completo (25%), seguido de ensino médio incompleto (18%), 5ª a 8ª série incompleta do ensino fundamental (16%) e ensino fundamental completo (14%); ao atingirem o ensino superior, essas taxas diminuíram bruscamente (4%). Nota-se que, dos casos confirmados de sífilis materna que evoluíram para sífilis congênita, 65% foram notificados durante o pré-natal, e 24%, durante o parto/curetagem. Conclusão: Verificou-se uma prevalência de casos de sífilis congênita quando a mãe tinha entre 20 e 29 anos, faixa etária que, historicamente, apresenta maior taxa de sífilis adquirida. Além disso, foram identificadas menores taxas de sífilis congênita quando a mãe da criança tinha atingido o ensino superior. Por fim, a detecção da sífilis materna (fator de risco para a sífilis congênita) no pré-natal se mostra insuficiente, visto que muitos desses casos são só detectados na hora no parto.
Influência da postectomia na prevenção das infecções sexualmente transmissíveis: uma revisão narrativa
Authors: Silva Georgia Fagundes Marinho da , Fosse Júnior Ângelo Maurílio , Castro Rodrigo Barros de , Arze Wilma Nanci Campos , Passos Mauro Romero Leal
Published: May 2024

Introdução: A postectomia ou circuncisão é um procedimento cirúrgico com o objetivo de remover o anel fibrótico prepucial permitindo a exteriorização permanente da glande, facilitando a higiene local e o fluxo urinário. Diversos estudos vêm sendo realizados com o intuito de avaliar o papel da postectomia como prevenção das infecções sexualmente transmissíveis (ISTs). Diversos estudos de coorte, assim como metanálises, afirmam que homens circuncidados têm menores chances de contrair ISTs e o efeito protetor pode ser devido ao fato de tornar o pênis menos suscetível a microfissuras, especialmente durante o ato sexual, o que favorece a entrada de patógenos. Objetivo: Realizar uma revisão narrativa da literatura para avaliar a influência da postectomia na prevenção das ISTs. Métodos: Realizou-se uma busca ativa, entre abril e maio de 2023, nas bases de dados National Library of Medicine (PubMed) e Scientific Eletronic Library Online (SciELO) com os descritores “male circumcision” (circuncisão masculina), “infectious diseases” (doenças infecciosas), “benefits of male circumcision” (benefícios da circuncisão masculina), “circumcision and sexual behavior” (circuncisão e comportamento sexual), IST e DST. Foram incluídos artigos escritos originalmente em português e inglês. Resultados: A revisão narrativa mostrou que a postectomia está associada a menores taxas de ISTs, especificamente causadas pelo Vírus da Imunodeficiência Adquirida (HIV), pelo papilomavírus humano (HPV) e pelo Vírus Herpes Simplex (HSV). Esses benefícios de prevenção de ISTs também se estendem às parceiras, que têm taxas reduzidas de sífilis, HPV, vaginose bacteriana e tricomoníase. Conclusão: É notório que políticas públicas para o desenvolvimento de campanhas estimulando a realização de postectomia podem ser uma importante estratégia na prevenção das ISTs. No entanto, outras formas de prevenção de ISTs não devem ser abandonadas e substituídas pela circuncisão.

Introdução: As infecções sexualmente transmissíveis (ISTs) são consideradas um problema de saúde pública mundial, e a população privada de liberdade é um dos grupos mais vulneráveis, tendo cinco vezes mais chances de ser infectada do que a população em geral. Objetivo: Analisar a epidemiologia das ISTs em um complexo penitenciário no Nordeste brasileiro. Métodos: Trata-se de um estudo observacional, analítico e transversal, realizado em um complexo penitenciário masculino em Sergipe. Os dados foram coletados por meio de formulário e analisados pelo Statistical Package for the Social Sciences (SPSS). Foram realizados testes rápidos para HIV, sífilis, hepatites B e C em todos que aceitaram participar da pesquisa. Os preceitos éticos foram preservados pela Resolução n. 466/2012. Resultados: Participaram da pesquisa 1.835 internos, dos quais foram rastreados 23 para HIV, 250 para sífilis, 11 para hepatite B e 237 para hepatite C. A prevalência de ISTs foi predominante em pardos e pretos (82,4%), com média de 30,8 anos (DP=8,9), ensino fundamental (71,1%) e residentes da zona urbana (85%). Em relação aos hábitos e às práticas sexuais, 37,1% realizaram tatuagem no complexo penitenciário, 20,1% compartilham lâminas de barbear, 57,9% utilizam o preservativo às vezes, 78,4% referem o uso de bebida alcoólica antes ou durante as relações sexuais e 73,6% confirmaram já ter feito a utilização de drogas em algum momento da relação sexual. No tocante conhecimento, 67,9% acreditam que HIV e AIDS são a mesma coisa, 56,6% afirmaram que a transmissão das ISTs ocorre por meio da picada do mosquito, 60,7% que ocorre por meio do beijo e 61,5% informaram que nunca realizaram testes rápidos ou laboratoriais para ISTs. Conclusão: Os fatores como baixa escolaridade, realização de tatuagens no complexo e utilização de álcool e drogas nas relações mostraram-se mais prevalentes, fato que sugere alto risco para desenvolvimento de ISTs. A baixa testagem para IST nessa população salienta uma preocupação coletiva com a saúde, sobretudo quanto a quebra da cadeia de transmissão e o diagnóstico precoce.

En los resultados, se muestran las condiciones en las que deben trabajar estas comunidades y las distintas adaptaciones que han realizado para poder seguir desarrollando sus actividades.
HANK beyond FIRE: Amplification, forward guidance, and belief shocks
Authors: Gallegos José-Elías
Published: May 2024

The transmission channel of monetary policy in the benchmark New Keynesian (NK) framework relies on the counterfactual Full Information Rational Expectations (FIRE) assumption, particularly at the general equilibrium (GE) dimension. I relax the Full Information assumption and build a Heterogeneous-Agents NK model under financial frictions and dispersed information. I find that the amplification multiplier of monetary policy is dampened by the lessened role of GE effects. I then conduct the standard full-fledged NK analysis: the determinacy region is widened as a result of as if aggregate myopia, and the framework beyond FIRE does not suffer from the forward guidance puzzle. Finally, I find that transitory “animal spirits” shocks generate persistent effects.

Objective: Conduct an integrative review of the literature on the effectiveness of orthopedic tenodesis surgery on flexion and supination strength. Methods: The question was based on the acromion peak: How effective is orthopedic tenodesis surgery? The literature review was carried out considering only clinical trials. Result: Taking into account that the strength between the operated and non-operated elbow does not have a significant difference (p>0.005), for example, p=0.345 for flexion and p=0.114 for supination, demonstrating good post-operative results. In another study, we can also evaluate this improvement, where the non-operated side has p=0.210 and the postoperative side has p=0.169. After treatment, 98% of patients recover supination strength and 94% flexion strength, with 73% of these patients within the expected range for a normal population. Conclusion: From reading and analyzing the articles, it was observed that tenodesis surgery was a safe, effective and aesthetically satisfactory procedure, as there is no aesthetic or functional difference between the operated side and the postoperative side.

Published: May 2024

Editor’s note: The aim of the Geology and Mining series is to introduce early career professionals and students to various aspects of mineral exploration, development, and mining in order to share the experiences and insight of each author on the myriad of topics involved with the mineral industry and the ways in which geoscientists contribute to each.

Water has always been an important issue for mineral exploration and mining companies. In recent years, water-related issues have increasingly placed a constraint on the development of new projects, while mine closure issues have created billion-dollar legacies for governments. Water access and management creates not only project risks but also opportunities. There are opportunities for geoscientists to help mitigate water-related issues early in a development, particularly for the economic geologists who play a crucial role in gathering data and geologic understanding during the early mine life cycle. Geologists can contribute to the understanding of baseline water systems and help to mitigate the potential effects that mining may pose for local ecosystems and to the communities that depend on them.
Drivers of Global Mineral Demand: 1900–2050
Authors: Lynch Martin
Published: May 2024

Editor’s note: The aim of the Geology and Mining series is to introduce early career professionals and students to various aspects of mineral exploration, development, and mining in order to share the experiences and insight of each author on the myriad of topics involved with the mineral industry and the ways in which geoscientists contribute to each.

The global demand for minerals has long been known to be characterized by periods of high demand followed by periods of low demand. These are often referred to as cycles. There are cycles of short (multiyear) duration and cycles of long (multidecade) duration. This paper seeks to explain the driving forces behind the long-duration cycles. There have been five such cycles since 1900. Four of them were in the 20th century, and the fifth was the China mining boom, which lasted from about 2000 to 2015. I interpret the main driver of these cycles to be the pace of urban, or suburban, construction. When this is proceeding at a rapid pace, global mineral demand is high. When construction activity slows, mineral demand slows with it.

In the 20th century it was the nations of Europe, North America, and, later in the century, the Soviet Union and Japan that were home to most of the world’s construction activity. Their economic fortunes drove the century’s four long-duration cycles. The century began with a 30-year period of high demand driven by the transformation of these economies from predominantly agriculture based to predominantly urban industrial. It ended with a nearly 30-year period of low demand as these same economies, having already urbanized, moved into being predominantly service-based economies, which have a lower per capita mineral demand. At the beginning of the 21st century, China took the lead with its remarkable transformation from an economy that was farm based to one that was urban industrial, which drove global mineral demand to a high level.

I argue that the world is now heading into a 30-year period of low urban construction-driven demand as China turns away from reform, India discovers that its economic success is built on weak foundations, and the “advanced countries” continue with their metals-lite transformation toward ever more sophisticated service activities. However, urban construction may be about to be displaced as the principal driver of global mineral demand. This new driver is the restructuring of global energy systems, or, to be more specific, the shift from hydrocarbon-based energy to solar and wind-based energy. Producing energy from solar and wind is far more materials-intensive than from hydrocarbons. Will this shift propel global mineral demand back to high?
Another Look at Marine Minerals
Authors: Hannington Mark , Petersen Sven , Jamieson John
Published: May 2024

Deep-sea mining is taking another step closer to reality. Early leases for exploration in the central Pacific manganese nodule fields and elsewhere in the oceans are coming to an end, and contractors are faced with a choice—extend the licenses to continue exploration or apply to mine the deposits they have found. The first 15-year licenses were originally signed into effect by the International Seabed Authority (ISA) in 2001 and began to expire in 2016. With no operations in a position to commence mining and, more importantly, no regulations in place to allow it, most exploration licenses were simply renewed. Eight of the original licenses were extended for five more years, some twice, and new licenses have been granted. Today, there are 31 contracts for exploration: 19 for manganese nodules, 7 for sea-floor massive sulfides, and 5 for Co-rich crusts. The first contract for massive sulfide exploration expires in 2026; the first for Co-rich crusts expires in 2029. Meanwhile, there is strong interest from a number of countries in the mineral resource potential of their exclusive economic zones (EEZs), particularly Japan and Norway. Against this backdrop of rapidly shifting exploration activity, it may be time to take another look at marine minerals as a resource for the future. In a report entitled “The Future of the Ocean Economy by 2030,” the Organization for Economic Cooperation and Development (OECD) asked, “What new developments could result in a complete revision of offshore mineral potential?” For most parts of the oceans, the answer to this question is plagued by inadequate mapping and a lack of geologic knowledge as a basis for assessing the resources. However, new approaches to exploration are emerging, and recent discoveries, such as on the continental shelf and beneath the cover of sediment, are changing our view of the resource potential.
Arthroscopic evaluation of the rotator cuff vasculature: inferences into the pathogenesis of cuff tear and re-tear
Authors: Gumina Steafano , Song Hyun Seok , Kim Hyungsuk , Candela Vittorio
Published: May 2024

Background: Little is known about alterations of the rotator cuff (RC) macroscopic vasculature associated with medical conditions and/or habits that predispose a person to diseases of the peripheral microcirculation. The high frequency of cuff tear and re-tear in patients with diabetes, hypercholesterolemia, uncontrolled arterial hypertension, or metabolic syndrome may be due to tissue hypovascularity.Methods: The macroscopic vasculature of both the articular and bursal sides of the posterosuperior RC was evaluated arthroscopically in 107 patients (mean age, 58.2 years) with no RC tear. Patients were divided into three groups according to medical comorbidities and lifestyle factors (group I, none; group II, smokers and/or drinkers and one comorbidity; and group III, two or more comorbidities). Pulsating vessels originating from both the myotendinous and osteotendinous junctions were assessed as “clearly evident,” “poorly evident,” or “not evident.” Results: Groups I, II, and III comprised 36, 45, and 26 patients, respectively. Within the myotendinous junction, vessels were visualized in 22 group I patients (61%), 25 group II patients (55%), and 6 group III patients (23%) (P=0.007). Pulsating arterial vessels originating from the osteotendinous junction were seen in 42%, 36%, and 0% of patients, respectively (P<0.001). Within the bursal side of the RC, a dense anastomotic network was visualized (either clearly or poorly) in 94% (34), 80% (36), and 35% (9) of patients, respectively (P<0.001).Conclusions: The macroscopic vasculature of the RC is influenced by pre-existing diseases and lifestyle factors, which may impair peripheral microcirculation. Level of evidence: III.

Objectives: To evaluate the proportion of Helicobacter pylori resistant to tetracyclines, amoxicilline, furazolidone, clarithromycin, fluoroquinolones and amoxicillin in Brazil and to present genotypic characteristics of strains. Methodology: Search in PubMed, SciELO, VHL and Medline. Twelve Brazilian studies on resistant Helicobacter pylori were selected, with a total of 2,038 patients. The options were performed with a confidence interval of 95% and an alpha of 0.05 using the software RStudio5.0. Results: low resistance rate for 04 antibiotics, being lower than the 15% threshold considered for empirical treatment. However, for metronidazole the rate of 43% and clarithromycin 16% macrolide and amoxicillin increased resistance when compared to previous years. The Southeast region had the highest rates. A clarithromycin ae A2147 in the 23s 23s RNA gene was the most prevalent conferring clear resistance. Conclusion: The increase in resistance to clarithromycin and amoxicillin resistance demonstrates that the factors that still increase for the acquisition of resistance still exist. Therefore, constant epidemiological surveillance is necessary so that we are aware of the resistance profile, performing assertive therapy.

The Internet of Medical Things (IoMT) has paved the way for innovative approaches to collecting and managing medical data. With the large and sensitive medical data being processed hence, the need for a strong identity and privacy become necessary. The present paper suggests a comprehensive method of PriMedGuard which aims at protection of the personal medical information. The first stage will be data collection from devices and sensors, then data cleaning to transform the data into the required format. There is also a safety system in the system that registers and authenticates authorized entities as well as ETDO (Enhanced Tasmanian Devil Optimization algorithm) is used for generating asymmetric cryptographic keys. The data is encrypted using the Secure Bit-Count Transmutation (SBCT) Data Encryption Algorithm and then put in the locations provided by the InterPlanetary File System (IPFS), a decentralized and distributed storage system. A safe smart contract on the blockchain is created so that the data retrieval is secure and MedSecEnsemble Detection is proposed as an intrusion detection technique in the IoMT network. By using this method, data will stay available while at the same time integrity, confidentiality and protection against vulnerabilities are ensured. Hence, the Internet of Medical Things ecosystem will be secured from unauthorized access and possible security threats…

Tulisan ini memberikan tinjauan mendalam terhadap antropologi ekonomi petani dan nilai-nilai Islam dalam konteks kehidupan masyarakat Sabapadang. Masyarakat Sabapadang, yang diwarnai oleh kegiatan pertanian sebagai salah satu sumber utama ekonomi mereka, juga tercermin dalam pandangan mereka terhadap nilai-nilai Islam dalam kehidupan sehari-hari. Penelitian ini menggunakan pendekatan deskriptif kualitatif untuk menggambarkan hubungan patron-klien yang terjadi di antara penderes pohon karet dan tauke getah di masyarakat Sabapadang. Tujuan utama penelitian ini adalah untuk mengungkapkan kondisi kehidupan ekonomi para penderes pohon karet di desa Sabapadang, mengidentifikasi pola hubungan patron-klien yang mendasari interaksi antara mereka dengan tauke getah, dan menganalisis faktor-faktor yang menjaga keberlanjutan hubungan ini. Hasil penelitian menunjukkan bahwa penderes pohon karet secara berkelanjutan terlibat dalam interaksi ekonomi dengan tauke getah. Masyarakat Sabapadang sangat bergantung pada tauke dalam aspek ekonomi mereka. Salah satu bentuk interaksi yang menonjol adalah ketika penderes mengalami kesulitan keuangan dan meminjam uang dari tauke. Sebagai imbalannya, penderes diharuskan untuk menjual hasil getah mereka kepada tauke, sering kali dengan harga yang lebih rendah daripada harga pasar, tanpa penentuan waktu yang pasti. Hubungan patron-klien antara penderes pohon karet dan tauke getah terjaga dengan lancar karena kedua belah pihak saling membutuhkan, baik dari segi ekonomi maupun sosial.
A damage prediction method for building concrete based on improved BP neural network
Authors: Xie Yuntao
Published: May 2024

Concrete is widely used in civil engineering, and fiber materials are usually added to building concrete to enhance its durability. In order to study the freeze-thaw damage performance of different fiber reinforced concrete mixtures and accurately predict the degree of freeze-thaw damage of fiber reinforced concrete with different ratios under salt freezing conditions, this paper proposes an improved BP neural network-based method for predicting freeze-thaw damage in building concrete. Firstly, freeze-thaw cycle tests were conducted on fiber reinforced concrete with different proportions to study the variation patterns of concrete quality loss rate and dynamic elastic modulus; Then, based on BP neural network and particle swarm optimization algorithm, a concrete damage prediction model is established; Finally, conduct optimization based on the learning samples and compare and analyze the prediction errors of the model. The method proposed in this article has been verified to have good accuracy and stability.

Authors: Zhang Yixin
Published: May 2024

Considering that the popularity of electric vehicle trucks (EVs) is growing, this paper takes Teslas Cybertruck as an example and discusses its power system, autonomous driving system, design concepts and materials. The purpose of this research is to explore the trends of future automobile development that are more environmentally friendly, more capable of living, more intelligent, and more multi-functional. Through the analysis, it can be found that the future automobile technology will develop in the direction of electrification, intelligence, multi-function and multi-modal. First of all, vehicles are more inclined to use battery engines with stronger endurance and faster charging speed to further reduce energy consumption and improve efficiency. Secondly, to improve fully autonomous driving technology, future vehicles tend to combine artificial intelligence (AI) with driving control systems. Moreover, according to the different needs of different models, the most suitable design scheme is combined with aerodynamics, and the materials with stronger strength, lighter weight and easier recycling are selected for the manufacture of the body.
A review for air fermentation to produce the air-based protein
Authors: Tang Guangjian
Published: May 2024

As the worlds population develops, there will be an increasing amount of requirement for food sources, however, traditional agriculture has been limited by many factors, like the availability of new farmland, the support of fertilizer, and the potential pollution of the growing process. Air-based meat provides an ingenious solution to this circumstance. The technology for producing protein uses air as the raw material, which means that regardless of climate conditions or seasons, protein can be produced, and it is produced within a few days rather than months, making air-based protein production gain a higher efficiency. Moreover, this process requires only a small portion of the land used in traditional meat production. However, there are several uncertainties that made this strategy have a hard time to extensively put into effect yet. The data and information in this paper are analyzed and derived from authoritative dissertations and academic websites. This paper will examine this technology from different perspectives to illustrate that advanced strategy in more detail.

The recent surge in artificial intelligence has escalated the demand for computing performance and storage capability in information processing hardware. However, in traditional von Neumann architecture, the processing and memory units are connected by a bus with limited bandwidth, which leads to excessive time and power consumption in data transfer. To address this issue, the emerging neuromorphic architecture co-locates the memory and processing functionalities by mimicking the information processing akin to the human brain. The inefficiency of traditional technology in neuromorphic hardware has led to extensive interest in novel memristive devices. The two-dimensional (2D) transition metal dichalcogenides (TMDCs) exhibit appealing characteristics for memristive devices, including tunable bandgap, high mobility at atomic thickness, and the rich possibility of defect engineering. This review focuses on the switching mechanisms of memristive devices based on 2D TMDCs. Additionally, properties and performances of 2D TMDCs-based memristive devices are also summarized in this review with respect to different switching mechanisms.
