Authors: Miao Fahui , Li Hangyu , Yan Guanjie , Mei Xiaojun , Wu Zhongdai , Zhao Wei , Liu Tao , Zhang Hao
Published: July 2024

Maritime UAV path planning is a key link in realizing the intelligence of maritime emergency transportation, providing key support for fast and flexible maritime accident disposal and emergency material supply. However, most of the current UAV path planning methods are designed for land environments and lack the ability to cope with complex marine environments. In order to achieve effective path planning for UAV in marine environments, this paper proposes a Directional Drive-Rotation Invariant Quadratic Interpolation White Shark Optimization algorithm (DD-RQIWSO). First, the directional guidance of speed is realized through a directional update strategy based on the fitness value ordering, which improves the speed of individuals approaching the optimal solution. Second, a rotation-invariant update mechanism based on hyperspheres is added to overcome the tracking pause phenomenon in WSO. In addition, the quadratic interpolation strategy is added to enhance the utilization of local information by the algorithm. Then, a wind simulation environment based on the Lamb–Oseen vortex model was constructed to better simulate the real scenario. Finally, DD-RQIWSO was subjected to a series of tests in 2D and 3D scenarios, respectively. The results show that DD-RQIWSO is able to realize path planning under wind environments more accurately and stably.
Numerical Research on a T-Foil Control Method for Trimarans Based on Phase Lag
Authors: Sun Yifang , Wang Yiqun , Zhang Dapeng , Wu Zongduo , Jin Guoqing
Published: July 2024

The lift force of a T-foil, which varies with ship motion, can counteract the wave exciting force during wave encounters. The phase difference between the periodic lift force and the wave exciting force significantly impacts the T-foil’s effectiveness. This study investigates the phase difference between lift force and motion to optimize the control equation for the T-foil’s angle, thereby reducing negative feedback. The T-foil’s hydrodynamic performance is first calculated using computational fluid dynamics. Time-domain calculations of the phase lag between lift force and motion under open-loop control in still water are then used to determine the dimensionless phase lag of the T-foil’s angle at various frequencies, facilitating further optimization of the control method. Finally, calculations of trimaran heave and pitch in regular waves are conducted. The results demonstrate that, under phase lag control, the T-foil’s lift force phase precedes ship motion by approximately 0.2 s, reducing hysteresis in the anti-vertical motion effect. Comparisons of vertical hull motions between different control methods reveal a 20% reduction in vertical motion with phase lag control compared to pitch control. This study concludes that phase lag is a crucial factor in T-foil control optimization.

Published: July 2024

This article is about the diversity of diatoms in the benthos of the upper sublittoral near Kazantip Cape, located on the shore of the Sea of Azov in the northeastern part of Crimea. The study was conducted in 2022 and 2023 at a depth of 0.1 to 1 m at temperatures from 3.7 °C to 29 °C and salinity from 13.6 to 15.6 psu on the following 11 species of macroalgae: Phaeophyta of Ericaria crinita, Gongolaria barbata, and Cladosiphon mediterraneus; Chlorophyta—Bryopsis hypnoides, Cladophora liniformis, Ulva intestinalis, and Ulva linza; and Rhodophyta—Callithamnion corymbosum, Ceramium arborescens, Polysiphonia denudata, and Pyropia leucosticta. A total of 97 taxa of Bacillariophyta belonging to 3 classes, 21 orders, 30 families, and 45 genera were found. The highest number of diatom species was found on U. linza (61 species), P. denudata (45), E. crinita (40), the lowest number was recorded on thalli P. leucosticta (9). On macroalgae were found of 80% benthic diatoms, 50% marine species, 36% brackish-marine, 9% freshwater, 5% brackish, and 36% cosmopolites. The maximum abundance of the diatom community was 243.4 × 103 cells/cm2 (P. denudata in September at 23.9 °C and 15.0 psu) with dominance by the diatom of Licmophora abbreviata, and the minimum was 3.8 × 103 cells/cm2 (P. leucosticta in January at 3.7 °C and 15.0 psu). The presence in the epiphyton of diatoms—indicators of moderate organic water pollution (32 species), which developed in masse in late summer—indicate a constant inflow of organic matter into the coastal waters of the Kazantip Cape. The bioindicator and statistical studies indicate the effectiveness of the conservation regime, especially at stations within the IUCN reserve, despite relatively high saprobity rates at stations exposed to recreational pressure and poorly treated domestic wastewater.
Fungal Abscess of Anterior Nasal Septum Complicating Maxillary Sinus Fungal Ball Rhinosinusitis Caused by Aspergillus flavus: Case Report and Review of Literature
Authors: Yang Shih-Wei , Luo Cheng-Ming , Cheng Tzu-Chien
Published: July 2024

Anterior nasal septum abscess is not a rare clinical disease entity. In terms of the etiologies of the disease, bacteria are obviously more common than fungi. Fungal culture and pathological examination are essential for diagnosis of a fungal abscess of the anterior nasal septum and the basis of prescription of antifungal agents. We report a 57-year-old male patient who came to our outpatient clinic due to refractory nasal congestion for 3 weeks despite receiving treatments by a local medical doctor. Radical surgery with postoperative adjuvant radiotherapy for the right buccal cancer was carried out 14 years ago. The patient has diabetes mellitus and the blood sugar level has been well controlled by oral hypoglycemic agents over the past several years. Computed tomography revealed an abscess in the anterior septum along with rhinosinusitis. Incision and drainage of the nasal septum abscess and functional endoscopic sinus surgery were carried out. Fungal culture and pathological examination confirmed a fungal abscess in the anterior nasal septum and fungal ball rhinosinusitis. Antibiotics and an antifungal agent were given, and the postoperative course was uneventful. A dialectical argument was made regarding the causal relationship between the fungal abscess of the anterior nasal septum and maxillary fungal ball sinusitis. A literature review of the previous case reports was carried out to elucidate the immune status of patients of this disease. In order to reach a rapid establishment of a fungal abscess of the anterior nasal septum, clinicians should keep this disease in mind and remain vigilant. An immuno-compromised status is more commonly found in patients with fungal abscess of the anterior nasal septum and is another important characteristic of this disease. Prompt diagnosis and effective treatment are equally important in patients with lower immune status of this kind, and the latter is based on the former.

Authors: Persakis Antonios , Tsakalos Ioannis
Published: July 2024

This study investigates the association between economic uncertainty and audit quality in the BRICS nations, examining both input-based (e.g., audit fees, auditor tenure) and output-based (e.g., restatements, total accruals) measures of audit quality. Utilizing a dataset of 83,511 firm-year observations from 1995–2022, it reveals a significant negative impact of economic uncertainty on audit quality. Additionally, the research explores the moderating role of CEO power, employing principal component analysis to merge various indicators of CEO influence. Findings indicate that powerful CEOs can mitigate the adverse effects of economic uncertainty on audit quality, suggesting a U-shaped relationship between CEO power and audit quality. Methodologically robust, employing techniques like two-stage least squares (2SLS) and two-stage system generalized method of moments (system GMM) to address endogeneity, the study offers a comprehensive analysis of audit quality in the context of economic fluctuations and corporate governance, contributing significantly to the understanding of these dynamics in emerging economies, particularly in the diverse and influential BRICS nations. This study’s findings have significant implications for stakeholders and policymakers, providing insights that can inform policy decisions and enhance corporate governance frameworks.
Land Use Carbon Emission Estimation and Simulation of Carbon-Neutral Scenarios Based on System Dynamics in Coastal City: A Case Study of Nantong, China
Authors: Xu Qingyun , Li Kongqing
Published: July 2024

Land use directly affects the carbon emissions and carbon stock of the ecosystem, and indirectly affects the carbon emissions from anthropogenic activities, which occur more frequently in coastal regions. Taking Nantong City as an example, detailed carbon emission projects were classified and calculated for different land use types by combining land use images of five typical years. Based on the complex relationship between land use carbon emissions and socio-economic factors, the system dynamics model (SD) was used to simulate the land use carbon emissions from 2005 to 2060, and to construct carbon-neutral policy scenarios. Compared with inlands, carbon emissions from land use in Nantong are more pronounced than inland areas, and unique land use types, such as shallows, play an important role as carbon sinks. Total land use carbon emissions show an upward trend from 2005 to 2020 and carbon emissions from construction land dominate. Under the natural development condition, the total net carbon emissions of Nantong are about 4,298,250 tons in 2060, failing to achieve carbon neutrality. The scenario with all four policies adjusted (LO, IO, TP, and PC) has the best emission reductions, peaking at 10,949,010 tons of net carbon emissions in 2029 and reducing them to 1,370,202 tons in 2060, which is the scenario closest to the carbon-neutral target. Overall, this study provides a meaningful conclusion for the study of land use carbon emission characteristics and low-carbon pathways in coastal cities, which can guide the formation of government policies.

Authors: Kannan Vigneshwar , Zhang Tieling , Li Huaizhong
Published: July 2024

Bearing component damage contributes significantly to rotating machinery failures. It is vital for the rotor-bearing system to be in good condition to ensure the proper functioning of the machine. Over recent decades, extensive research has been devoted to the condition monitoring of rotational machinery, with a particular focus on bearing health. This paper provides a comprehensive literature review of recent advancements in intelligent condition monitoring technologies for rolling element bearings. Fundamental monitoring strategies are introduced, covering various sensing, signal processing, and feature extraction techniques for detecting defects in rolling element bearings. While vibration-based monitoring remains prevalent, alternative sensor types are also explored, offering complementary diagnostic capabilities or detecting different defect types compared to accelerometers alone. Signal processing and feature extraction techniques, including time domain, frequency domain, and time–frequency domain analysis, are discussed for their ability to provide diverse perspectives for signal representation, revealing unique insights relevant to condition monitoring. Special attention is given to information fusion methodologies and the application of intelligent algorithms. Multisensor systems, whether homogeneous or heterogeneous, integrated with information fusion techniques hold promise in enhancing accuracy and reliability by overcoming limitations associated with single-sensor monitoring. Furthermore, the adoption of AI techniques, such as machine learning, metaheuristic optimisation, and deep-learning methods, has led to significant advancements in condition monitoring, yielding successful outcomes with improved accuracy and robustness in various studies. Finally, avenues for further advancements to improve monitoring accuracy and reliability are identified, offering insights into future research directions.
Priority-Based Capacity Allocation for Hierarchical Distributors with Limited Production Capacity
Authors: Tong Jun , Zhou Xiaotao , Lei Lei
Published: July 2024

This paper studies the issue of capacity allocation in multi-rank distribution channel management, a topic that has been significantly overlooked in the existing literature. Departing from conventional approaches, hierarchical priority rules are introduced as constraints, and an innovative assignment integer programming model focusing on capacity selection is formulated. This model goes beyond merely optimizing profit or cost, aiming instead to enhance the overall business orientation of the firm. We propose a greedy algorithm and a priority-based binary particle swarm optimization (PB-BPSO) algorithm. Our numerical results indicate that both algorithms exhibit strong optimization capabilities and rapid solution speeds, especially in large-scale scenarios. Moreover, the model is validated through empirical tests using real-world data. The results demonstrate that the proposed approaches can provide actionable strategies to operators, in practice.
Enhancing Stability Criteria for Linear Systems with Interval Time-Varying Delays via an Augmented Lyapunov–Krasovskii Functional
Authors: Lee Dong-Hoon , Kim Yeong-Jae , Lee Seung-Hoon , Kwon Oh-Min
Published: July 2024

This work investigates the stability conditions for linear systems with time-varying delays via an augmented Lyapunov–Krasovskii functional (LKF). Two types of augmented LKFs with cross terms in integrals are suggested to improve the stability conditions for interval time-varying linear systems. In this work, the compositions of the LKFs are considered to enhance the feasible region of the stability criterion for linear systems. Mathematical tools such as Wirtinger-based integral inequality (WBII), zero equalities, reciprocally convex approach, and Finsler’s lemma are utilized to solve the problem of stability criteria. Two sufficient conditions are derived to guarantee the asymptotic stability of the systems using linear matrix inequality (LMI). First, asymptotic stability criteria are induced by constructing the new augmented LKFs in Theorem 1. Then, simplified LKFs in Corollary 1 are proposed to show the effectiveness of Theorem 1. Second, asymmetric LKFs are shown to reduce the conservatism and the number of decision variables in Theorem 2. Finally, the advantages of the proposed criteria are verified by comparing maximum delay bounds in four examples. Four numerical examples show that the proposed Theorems 1 and 2 obtain less conservative results than existing outcomes. Particularly, Example 2 shows that the asymmetric LKF methods of Theorem 2 can provide larger delay bounds and fewer decision variables than Theorem 1 in some specific systems.
An Overview of Postprocessing in Quantum Key Distribution
Authors: Luo Yi , Cheng Xi , Mao Hao-Kun , Li Qiong
Published: July 2024

Quantum key distribution (QKD) technology is a frontier in the field of secure communication, leveraging the principles of quantum mechanics to offer information-theoretically secure keys. Postprocessing is an important part of a whole QKD system because it directly impacts the secure key rate and the security of the system. In particular, with the fast increase in the photon transmission frequency in a QKD system, the processing speed of postprocessing becomes an essential issue. Our study embarks on a comprehensive review of the development of postprocessing of QKD, including five subprotocols, namely, parameter estimation, sifting, information reconciliation, privacy amplification, and channel authentication. Furthermore, we emphasize the issues raised in the implementation of these subprotocols under practical scenarios, such as limited computation or storage resources and fluctuations in channel environments. Based on the composable security theory, we demonstrate how enhancements in each subprotocol influence the secure key rate and security parameters, which can provide meaningful insights for future advancements in QKD.
Collision-Free Trajectory Planning Optimization Algorithms for Two-Arm Cascade Combination System
Authors: Xu Jingjing , Tao Long , Pei Yanhu , Cheng Qiang , Chu Hongyan , Zhang Tao
Published: July 2024

As a kind of space robot, the two-arm cascade combination system (TACCS) has been applied to perform auxiliary operations at different locations outside space cabins. The motion coupling relation of two arms and complex surrounding obstacles make the collision-free trajectory planning optimization of TACCS more difficult, which has become an urgent problem to be solved. For the above problem, this paper proposed collision-free and time–energy–minimum trajectory planning optimization algorithms, considering the motion coupling of two arms. In this method, the screw-based inverse kinematics (IK) model of TACCS is established to provide the basis for the motion planning in joint space by decoupling the whole IK problem into two IK sub-problems of two arms; the minimum distance calculation model is established based on the hybrid geometric enveloping way and basic distance functions, which can provide the efficient and accurate data basis for the obstacle-avoidance constraint condition of the trajectory optimization. Moreover, the single and bi-layer optimization algorithms are presented by taking motion time and energy consumption as objectives and considering obstacle-avoidance and kinematics constraints. Finally, through example cases, the results indicate that the bi-layer optimization has higher convergence efficiency under the premise of ensuring the optimization effect by separating variables and constraint terms. This work can provide theoretical and methodological support for the efficient and intelligent applications of TACCS in the space arena.

Published: July 2024

Salmonella enterica Typhimurium DT104 (S. Typhimurium DT104) is an important foodborne pathogen that is associated with poultry and poultry products. Currently, there is very little information on the underlying molecular mechanisms that allow DT104 to survive and propagate in poultry meat and the poultry processing environment. The current study assessed the global gene expression of DT104 in ground chicken extract (GCE) compared to brain heart infusion (BHI) medium using RNA-Seq technology. DT104 was grown to the early stationary phase (ESP), inoculated into GCE or BHI, and then re-grown to the log phase before RNA was extracted and transcripts were quantified by RNA-Seq. Gene expression for DT104 grown in GCE was then compared to that of DT104 grown in BHI for samples grown to the ESP. Growth in GCE resulted in the up-regulated expression of genes related to translation, carnitine metabolism (23–283-fold change), and cobalamin (vitamin B12) biosynthesis (14-fold change). In particular, the presence of carnitine in chicken meat, and thus, in GCE, which lacks carbohydrates, may allow Salmonella to utilize this compound as a carbon and nitrogen source. This study demonstrates that RNA-Seq data can provide a comprehensive analysis of DT104 gene expression in a food model for poultry products. This study also provides additional evidence for the importance of metabolic adaptation in the ability of S. enterica to successfully adapt to and occupy niches outside of its host and provides potential targets that could be used to develop intervention strategies to control Salmonella in poultry.

Published: July 2024

Clostridial myonecrosis, commonly known as gas gangrene (GG), is a rapidly progressing and potentially fatal bacterial infection that primarily affects muscle and soft tissue. In the United States, the incidence of GG is roughly 1000 cases per year, while, in developing countries, the incidence is higher. This condition is most often caused by Clostridium perfringens, a Gram-positive, spore-forming anaerobic bacterium widely distributed in the environment, although other Clostridium species have also been reported to cause GG. The CP genome contains over 200 transport-related genes, including ABC transporters, which facilitate the uptake of sugars, amino acids, nucleotides, and ions from the host environment. There are two main subtypes of GG: traumatic GG, resulting from injuries that introduce Clostridium spores into deep tissue, where anaerobic conditions allow for bacterial growth and toxin production, and spontaneous GG, which is rarer and often occurs in immunocompromised patients. Clostridium species produce various toxins (e.g., alpha, theta, beta) that induce specific downstream signaling changes in cellular pathways, causing apoptosis or severe, fatal immunological conditions. For example, the Clostridium perfringens alpha toxin (CPA) targets the host cell’s plasma membrane, hydrolyzing sphingomyelin and phosphatidylcholine, which triggers necrosis and apoptosis. The clinical manifestations of clostridial myonecrosis vary. Some patients experience the sudden onset of severe pain, swelling, and muscle tenderness, with the infection progressing rapidly to widespread tissue necrosis, systemic toxicity, and, if untreated, death. Other patients present with discharge, pain, and features of cellulitis. The diagnosis of GG primarily involves clinical evaluation, imaging studies such as X-rays, computer tomography (CT) scans, and culture. The treatment of GG involves surgical exploration, broad-spectrum antibiotics, antitoxin, and hyperbaric oxygen therapy, which is considered an adjunctive treatment to inhibit anaerobic bacterial growth and enhance the antibiotic efficacy. Early recognition and prompt, comprehensive treatment are critical to improving the outcomes for patients affected by this severe and life-threatening condition.

Authors: Nowicki Jarosław , Ratajczak Piotr , Szutowski Dawid
Published: July 2024

The objective of this study is to examine the relationship between macroeconomic variables and the financial liquidity of companies. In this context, two main research questions were formulated. Firstly, which macroeconomic variables impact the financial liquidity of companies? Secondly, what is the direction and strength of the influence of these macroeconomic variables on the financial liquidity of companies? This study employed panel data analysis conducted on an unbalanced panel of 5327 Polish enterprises over the period 2003–2021. The primary research method employed was linear regression (pooled OLS) with robust standard errors clustered at the firm level. The main results of this study indicate that (1) the majority of macroeconomic variables, which illustrate the overall efficiency of the economic system (GDP per capita, ratio of foreign trade goods balance to GDP, CPI, and money supply), demonstrate a positive relationship with corporate liquidity; only the consumption-to-GDP ratio exhibits a negative relationship; (2) a positive relationship was observed between the number of building permits for housing and financial liquidity; (3) variables from the informal institutional environment indicate a positive relationship for the employment rate and a negative relationship for the share of the pre-working age population in the overall population; (4) the relationship between the ratio of internal expenditures on research and development to GDP and corporate liquidity is positive. This study addresses limitations of previous research by examining the impact of macroeconomic factors, particularly those from the institutional and technical environment, on corporate financial liquidity.
Oxygen Measurement in Cuprate Superconductors Using the Dissolved Oxygen/Chlorine Method
Authors: Wei Yuliang , Yan Chengcheng , Kambe Shiro
Published: July 2024

We have developed a dissolved oxygen (DO) method with differential equation (DE) correction. We measured the oxygen content in La-based and Y-based superconductors, and succeeded in measuring the oxygen content simply in one-third of the time required by the iodometric titration method. However, there was a problem with Bi-based superconductors where the measured oxygen content was smaller compared to the iodometric titration method. We hypothesized that not only O2 but also Cl2 gas is generated when dissolving Bi-based superconductors and developed a dissolved oxygen/chlorine (DO/Cl) method with DE correction. This method uses only a dissolved oxygen sensor and a dissolved chlorine sensor to measure the dissolved oxygen and dissolved chlorine content in Bi2Sr2−xLaxCuOy, allowing for the calculation of copper valence and oxygen content. The results from the DO/Cl method with DE correction show that the measured copper valence and oxygen content differ very little from those obtained using the iodometric titration method, with discrepancies within 0.016 and 0.008, respectively. Additionally, this method reduces the measurement time by one-third compared to the iodometric titration method. The results demonstrate that the DO/Cl method with DE correction can effectively measure the copper valence and oxygen content in cuprate superconductors, and using hydrochloric acid as the experimental solution is superior to sulfuric acid and nitric acid.

O objetivo desse trabalho foi identificar os números de registros de acidentes ocorridos na extração de minério de ferro entre os anos de 2011 a 2020 onde foi utilizado como banco de dados os registros disponibilizados pelo Ministério do Trabalho (MTP). A exploração de minério no Brasil está diretamente atrelada a história de ocupação e colonização do território pelos portugueses. Em 2015, o Brasil foi o maior exportador de minérios da América Latina e o segundo maior do mundo, sendo responsável por cerca de 11% de todos os minérios exportados. Nesse contexto de expansão, a indústria mineradora, tem sido pressionada a melhorar seu desempenho social, ambiental e de desenvolvimento. A mineração apresenta risco grau 4, segundo classificação da Norma Regulamentadora 4 (NR 4) sendo considerado o mais perigoso do mundo para se trabalhar. Os acidentes de trabalho causam severos prejuízos a empresa e a sociedade, pois o contribuinte acaba arcando com parte do prejuízo e a empresa que muitas vezes perde mão de obra e vê sua imagem como corporação comprometida. É fundamental então entender a dinâmica dos acidentes acontecidos dentro dessa atividade. Após o estudo pode-se concluir que os números de acidentes são expressivos, porém apresentam uma redução ao longo dos anos, evidenciando que a empresas do segmento vem adotando as medidas de controle e prevenção dos riscos.

Published: July 2024

A Doença de Lyme (DL), causada pela bactéria Borrelia burgdorferi e transmitida por carrapatos do gênero Ixodes, apresenta manifestações clínicas variadas em estágios distintos. Inicialmente, o sinal mais característico é o eritema migratório, uma lesão cutânea acompanhada por sintomas como febre, fadiga, dor de cabeça e dores musculares. Se não tratada, a infecção pode progredir, afetando o sistema nervoso, coração e articulações, levando a meningite, neuropatia e artrite. A doença é geralmente classificada em três estágios: inicial localizado, disseminado precoce e disseminado tardio. O estágio inicial é marcado pelo eritema migratório e sintomas gripais. No estágio disseminado precoce, a infecção pode espalhar-se para várias partes do corpo. O estágio disseminado tardio pode ocorrer meses ou anos após a infecção inicial, com artrite crônica e sintomas neurológicos persistentes. O diagnóstico baseia-se na avaliação clínica e é frequentemente confirmado por testes laboratoriais, incluindo o teste ELISA seguido pelo Western Blot, para detectar anticorpos contra B. burgdorferi. Em alguns casos, testes de PCR identificam o DNA bacteriano em fluidos corporais. O tratamento padrão envolve o uso de antibióticos. Nos estágios iniciais, a doxiciclina, amoxicilina ou cefuroxima são prescritas. Para manifestações mais graves, como as que afetam o sistema nervoso ou o coração, ceftriaxona intravenosa pode ser necessária. A prevenção foca em evitar picadas de carrapatos, usando repelentes de insetos, roupas protetoras e realizando inspeções regulares de carrapatos após atividades ao ar livre. É crucial remover rapidamente qualquer carrapato encontrado na pele, já que a transmissão da bactéria geralmente requer a adesão do carrapato por mais de 24 horas. Perspectivas futuras incluem o desenvolvimento de vacinas e novas estratégias de diagnóstico e tratamento. Por fim, a DL é uma infecção complexa que requer uma abordagem multifacetada. A prevenção é essencial, enquanto a pesquisa de novas terapias e vacinas oferece esperança para o futuro.

O objetivo deste estudo foi avaliar as evidências científicas sobre o uso do telemonitoramento e telemedicina no acompanhamento de pacientes com Diabetes Mellitus. Realizou-se revisão de escopo da literatura de artigos publicados no período de 2016 a 2020, disponíveis na íntegra nas bases de dados: Pubmed, Cochrane e Embase. A partir dos critérios de inclusão/exclusão pré-estabelecidos, foram selecionados para compor a amostra desta revisão 10 artigos científicos. Por meio da análise dos estudos incluídos, notou-se que os ensaios clínicos focaram predominantemente no trato de pacientes com DM tipo 2, sendo que em sete foram inseridos o automonitoramento da glicemia capilar por parte do paciente. Em seis artigos a diminuição dos valores de hemoglobina glicada foi superior no grupo de intervenção em comparação ao grupo controle, com boa aceitação por parte dos pacientes e, em um deles, houve potencial diminuição dos custos em saúde. Conclui-se que ações de telemonitoramento e telemedicina podem ser consideradas boas estratégias para a melhoria da assistência a pacientes com DM no contexto da APS. No entanto, a aplicação do telemonitoramento em contexto brasileiro, demanda reflexão e o enfrentamento a possíveis desafios relacionados ao acesso das informações, considerando as desigualdades entre as diferentes regiões do país.

Os anti-inflamatórios não esteroidais (AINEs) são amplamente utilizados devido à sua eficácia no tratamento de condições inflamatórias, osteoartrites e controle da dor. No entanto, seu uso prolongado está associado a complicações renais, gastrointestinais e hepáticas, destacando a importância de uma avaliação cuidadosa dos riscos e benefícios. Este estudo consistiu em uma revisão integrativa da literatura, realizada nas bases de dados BVS/Lilacs, PubMed, Scielo e Science Direct. Foram utilizados termos de pesquisa como "AINE", "Anti-Inflamatório", "Intoxicação" e "Farmacovigilância" para identificar estudos relevantes publicados entre 2015 e 2024. Um total de 18 artigos foram selecionados para análise após exclusão de duplicidades e critérios de inclusão e exclusão. Os resultados destacaram associações entre o uso de AINEs e lesão renal aguda, doença renal crônica, sangramento gastrointestinal e doença hepática aguda, ressaltando a necessidade de uma abordagem individualizada na prescrição desses medicamentos. A seletividade para a COX e os grupos químicos dos AINEs influenciaram no manejo dos efeitos colaterais, enfatizando a importância da vigilância regular dos pacientes. Conclui-se, que uma prescrição cuidadosa e vigilância adequada são essenciais para garantir uma terapia eficaz e segura com AINEs, contribuindo para a segurança dos pacientes e orientação da prática clínica.

Se ha mostrado una creciente problemática en el incremento de consumo de comida rápida en el norte de México, aumentando significativamente el riesgo de padecer trastornos gastrointestinales, como gastritis, gastroenteritis, hígado graso, entre otros. Así mismo, se ha mostrado una relación significativa de este hábito con las enfermedades crónico-degenerativas relacionadas con la alimentación, como lo son la obesidad, sobrepeso, diabetes mellitus, enfermedades cardiovasculares, hasta algunos tipos de cáncer, lo cual es preocupante pues se han registrado como principal causa de muerte a nivel nacional. Para conocer las posibles causas de los habitantes de Nuevo León para el incremento del consumo de comida rápida, se realizó un análisis estadístico descriptivo encuestando a 52 habitantes de diversos municipios de Nuevo León, con lo que se observa que el 61% de los encuestados han presentado trastornos gastrointestinales relacionados con su alimentación, con una relación significativa con su estilo de vida acelerado, así como el tipo de trabajo que realizan los participantes, lo que permite concluir que el estilo de vida de los regiomontanos es clave para aumentar el consumo de comida rápida.

A conservação de alimento para uso no período da seca é fundamental para produtores de ruminantes, assim busca-se constantemente novas formas de se produzir forragem com qualidade e menor custo de produção. Diante disso avaliou-se a produtividade e qualidade de silagem de capim, de girassol e do consórcio. O experimento foi realizado na fazenda escola do Instituto Federal Goiano, Campus Iporá, em um solo classificado como Cambissolo Háplico, onde foram avaliados o girassol (Helianthus annuus cv. ‘Altis 99’) e o capim (Megathyrsus maximus cv. ‘BRS Quênia’), que foram semeados simultaneamente. A densidade de semeadura foi de 76 mil sementes e 5 kg de sementes por hectare de SPV (Semente pura viável) do girassol e de capim, respetivamente. Observamos que conforme aumenta a contribuição da produtividade de biomassa do girassol há tendência de redução na biomassa de capim, no sentido contrário, há comportamento similar, todavia com menor intensidade, observamos também que a biomassa produzida pelo consórcio proporciona equilíbrio nutricional ajustando o teor de gordura da silagem do girassol. Girassol e capim se complementam, sendo que o consórcio proporciona uma silagem de boa qualidade.

Published: July 2024

Introduction: The authors reviewed close/positive margins in cutaneous squamous cell carcinoma of the head and neck, ensuing recurrence, regional or systemic metastasis, mortality and follow-up management. Methods: The design was a systematised review from January 2000 to July 2021. The MEDLINE database was searched with 15 articles out of 3104 meeting the inclusion criteria. Pertinent references underpinning the National Comprehensive Cancer Network’s Squamous Cell Skin Cancer Guidelines Version 2.2022 were reviewed. Results: Overall, there were 13,671 cutaneous squamous cell carcinoma lesions. We found pooled rates for positive excision (14.6% at 99% CI [12.97, 16.26]), ensuing recurrence (14.7% at 99% CI [13.51, 15.83]), regional or systemic metastasis (33.8% at 99% CI [33.77, 33.87]), and mortality (46.6% at 99% CI [42.53, 50.65]). Positive excisions most frequently involved the deep margin (73.7%), nose (34.5%) and ear (33.14%). Re-excision of positive margins appeared to confer worse recurrence (35.4%). We found pooled rates for close/positive excision (17% at 99% CI [15.22, 18.84]), ensuing recurrence (17% at 99% CI [15.76, 18.16]), regional or systemic metastasis (30.4% at 99% CI [26.15, 34.73]), and mortality (46.6% at 99% CI [42.53, 50.65]). Mean follow up was 51 months. Surgical re-excision with adequate margins appeared to be most efficacious, followed by radiotherapy. Chemoradiation and chemotherapy appeared less efficacious. Conclusion: Surgical re-excision with adequate margins remains the gold standard for close/positive margins in cutaneous squamous cell carcinoma of the head and neck, followed by radiotherapy.

Considering the organizational success, employees performance has been accepted as among the fundamental role players. However, several organizational factors like abusive supervision, job stress, turnover intention, and agile leadership have been accepted as among the most critical determinants of such performance outcomes. The objective of this study is to assess the moderating effect of perceived organizational support on the relationships among abusive supervision, job stress, turnover intention, and agile leadership on employee performance in public firms in the UAE. A valid sample of 211 respondents from the public sector firms in UAE has been collected. The present study applies the measurement model and structural model assessment using the Smart PLS version 4. The findings confirm the presence of the internal consistency reliability, convergent validity, and discriminant validity of the latent constructs when examined through their relative items. Moreover, the structural equation modelling reveals that there is a significant impact of agile leadership, abusive supervision, and job stress on the employee performance among the public firms of UAE. Additionally, the findings state that there is a significant moderating effect of perceived organizational support on the relationship between agile leadership and employee performance, between abusive supervision and employee performance, and between job stress and employee performance, respectively. Based upon the given findings, several policy implications have also been suggested for the policymakers specifically at the public firms in UAE.
