Lean and Agile Supply Strategies in Distribution Centres to Deliver Value-Added Services (VAS)
Authors: Klundt Eduard , Towers Neil , Bechkoum Kamal
Published: July 2024

Background: This paper examines how logistics mangers increase performance by incorporating VAS in their distribution centres in the context of different natures of customer demand. The study is underpinned by the principles of lean and agile strategies as two key concepts that can be applied to respond to different customer expectations. Methods: Based on the phenomenological interpretivist paradigm, an empirical multiple-case study was conducted in German distribution centres operated by six companies. The empirical data were collected through semi-structured interviews, built on the triangulation of sources. Open, axial, and selective coding were employed to analyse data collected through eighteen in-depth interviews with managers from the distribution centres. Results: The findings indicated that the construct of customer demand forms different benefits that the logistics service providers can achieve through VAS. Simultaneously, various customer demands on VAS requires the distribution centres to focus on developing different operational capabilities to gain superior performance. Conclusions: Based on the research findings, a conceptual model was created. This model can support logistics service providers in improving company performance through effectively managing VAS in their distribution centres. The high dynamic VAS customer demand can bring more financial and non-financial benefits but needs higher flexibility in the warehouse operation system. Stable and predictable VAS, in turn, require a higher degree of standardisation.

Published: July 2024

5(S)-((3aR,4R,6aR)-2,2-Dimethyltetrahydrofuro[3,4-d][1,3]dioxol-4-yl)-2-phenyl-4,5-dihydrooxazole was synthesized from isosorbide in a three-step sequence, with an overall yield of 46%. The first reaction step involves a single regioselective ring-opening reaction of isosorbide with Me3SiI in the presence of acetone followed by an intramolecular nucleophilic substitution to transform the iodoalcohol into its corresponding epoxide. The last reaction allows the formation of the oxazoline ring directly from the epoxide with benzonitrile in the presence of BF3·Et2O.

Published: July 2024

The aim of this work is to study the phase transformations, microstructures, and mechanical properties of martensitic stainless steel (MSS) 410 deposits produced by laser powder-directed energy deposition (LP-DED) additive manufacturing. The LP-DED MSS 410 deposits underwent post-heat treatment, which included austenitizing at 980 °C for 3 h, followed by different tempering treatments at the temperatures of 250, 600, and 750 °C for 5 h, respectively. The analyses of phase transformations and microstructural evolutions of LP-DED MSS 410 were carried out using X-ray diffraction, SEM-EDS, and EBSD. Vickers hardness and tensile strength properties were also measured to analyze the effects of the different tempering heat treatments. It revealed that the as-built MSS 410 has very fine lath martensite, high hardness of about 480 HV1.0, and tensile strength of about 1280 MPa, but elongation was much lower than the post-heat-treated ones. Precipitations of chromium carbide (Cr23C6) were most commonly observed at the grain boundaries and the entire matrix at the tempering temperatures of 600 °C and 750 °C. In general, the tensile strength decreased from 1381 MPa to 688 MPa as tempering temperatures increased to 750 °C from 250 °C. Additionally, as the tempering temperature increased, the chromium carbide and tempered martensite structures became coarser.
Curcumin-Assisted Synthesis of MoS2 Nanoparticles as an Electron Transport Material in Perovskite Solar Cells
Authors: Murugesan Vajjiravel , Rathinam Balamurugan
Published: July 2024

Recently, two-dimensional (2D) transition metal dichalcogenides (2D TMDs), such as molybdenum sulfide (MoS2) and molybdenum selenide (MoSe2), have been presented as effective materials for extracting the generated holes from perovskite layers. Thus, the work function of MoS2 can be tuned in a wide range from 3.5 to 4.8 eV by adjusting the number of layers, chemical composition, elemental doping, surface functionalization, and surface states, depending on the synthetic approach. In this proposed work, we attempt to synthesize MoS2 nanoparticles (NPs) from bulk MoS2 using two steps: (1) initial exfoliation of bulk MoS2 into few-layer MoS2 by using curcumin-cholesteryl-derived organogels (BCC-ED) and curcumin solution in ethylene diamine (C-ED) under sonication; (2) ultrasonication of the subsequently obtained few-layer MoS2 at 60–80 °C, followed by washing of the above chemicals. The initial treatment with the BCC-ED/C-ED undergoes exfoliation of bulk MoS2 resulted in few-layer MoS2, as evidenced by the morphological analysis using SEM. Further thinning or reduction of the size of the few-layer MoS2 by prolonged ultrasonication at 60–80 °C, followed by repeated washing with DMF, resulted in uniform nanoparticles (MoS2 NPs) with a size of ~10 nm, as evidenced by morphological analysis. Since BCC-ED and C-ED produced similar results, C-ED was utilized for further production of NPs over BCC-ED owing to the ease of removal of curcumin from the MoS2 NPs. Utilization of the above synthesized MoS2 NPs as an ETL layer in the cell structure FTO/ETL/perovskite absorber/spiro-OMeTAD/Ag enhanced the efficiency significantly. The results showed that MoS2 NPs as an ETL exhibited a power conversion efficiency (PEC) of 11.46%, a short-circuit current density of 18.65 mA/cm2, an open-circuit voltage of 1.05 V, and a fill factor of 58.66%, at the relative humidity of 70 ± 10% (open-air conditions) than that of the ED-treated MoS2 devices without curcumin. These results suggest that the synergistic effect of both curcumin and ED plays a critical role in obtaining high-quality MoS2 NPs, beneficial for efficient charge transport, lowering the crystal defect density/trap sites and reducing the charge recombination rate, thus, significantly enhancing the efficiency.

Authors: Yan Jin , Lu Jiancheng , Sheng Yuxuan , Sun Yin , Zhang Dapeng
Published: July 2024

Transition metal sulfides are widely used in supercapacitor electrode materials and exhibit excellent performance because of their rich variety, low price, and high theoretical specific capacity. At present, the main methods to prepare transition metal sulfides include the hydrothermal method and the electrochemical method. In order to further improve their electrochemical performance, two aspects can be addressed. Firstly, by controllable synthesis of nanomaterials, porous structures and large surface areas can be achieved, thereby improving ion transport efficiency. Secondly, by combining transition metal sulfides with other energy storage materials, such as carbon materials and metal oxides, the synergy between different materials can be fully utilized. However, future research still needs to address some challenges. In order to guide further in-depth research, it is necessary to combine the current research-derived knowledge and propose a direction for future development of transition metal sulfide electrode materials.

Published: July 2024

Morse code recognition plays a very important role in the application of human–machine interaction. In this paper, based on the carbon nanotube (CNT) and polyurethane sponge (PUS) composite material, a flexible tactile CNT/PUS sensor with great piezoresistive characteristic is developed for detecting Morse code precisely. Thirty-six types of Morse code, including 26 letters (A–Z) and 10 numbers (0–9), are applied to the sensor. Each Morse code was repeated 60 times, and 2160 (36 × 60) groups of voltage time-sequential signals were collected to construct the dataset. Then, smoothing and normalization methods are used to preprocess and optimize the raw data. Based on that, the long short-term memory (LSTM) model with excellent feature extraction and self-adaptive ability is constructed to precisely recognize different types of Morse code detected by the sensor. The recognition accuracies of the 10-number Morse code, the 26-letter Morse code, and the whole 36-type Morse code are 99.17%, 95.37%, and 93.98%, respectively. Meanwhile, the Gated Recurrent Unit (GRU), Support Vector Machine (SVM), Multi-Layer Perceptron (MLP), and Random Forest (RF) models are built to distinguish the 36-type Morse code (letters of A–Z and numbers of 0–9) based on the same dataset and achieve the accuracies of 91.37%, 88.88%, 87.04%, and 90.97%, respectively, which are all lower than the accuracy of 93.98% based on the LSTM model. All the experimental results show that the CNT/PUS sensor can detect the Morse code’s tactile feature precisely, and the LSTM model has a very efficient property in recognizing Morse code detected by the CNT/PUS sensor.

Published: July 2024

This paper presents a new framework using MEMS flow sensors on turbine blades (SOTB) to investigate unsteady flow features of a rotating wind turbine. Self-heating flow sensors were implemented by the U18 complementary metal-oxide semiconductor (CMOS) MEMS foundry provided by Taiwan Semiconductor Research Institute (TSRI). Flow sensor chips with a size of 1.5 mm × 1.5 mm were parylene-coated, output via a wireless data acquisition system (WDAQ), and mounted at the root, middle and tip of a 1.2 m diameter semi-rigid turbine blade of a 400 W horizontal axis wind turbine (HAWT). The instantaneous angles of attack (AOAs) of the SOTB were found to be 46~62°, much higher than the general stall AOA of 15°, but were accurate considering the normal detection of the flow sensors. The computational fluid dynamics (CFD) simulation of the HAWT was also compared with the SOTB output. The onsite measurement herein revealed that the 3D secondary flow increment, mostly obvious near the middle part of the turbine blades, degraded both the sensor and the turbine performance and initially justified the onsite measurement application.

The present article describes the synthesis of an isonicotinate-derived meso-arylporphyrin, that has been fully characterized by spectroscopic methods (including fluorescence spectroscopy), as well as elemental analysis and HR-MS. The structure of an n-hexane monosolvate has been determined by single-crystal X-ray diffraction analysis. The radical scavenging activity of this new porphyrin against the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical has been measured. Its antifungal activity against three yeast strains (C. albicans ATCC 90028, C. glabrata ATCC 64677, and C. tropicalis ATCC 64677) has been tested using the disk diffusion and microdilution methods. Whereas the measured antioxidant activity was low, the porphyrin showed moderate but encouraging antifungal activity. Finally, a study of its effect on the germination of lentil seeds revealed interesting allelopathic properties.
Recent Advances in the Determination of Major and Trace Elements in Plants Using Inductively Coupled Plasma Optical Emission Spectrometry
Authors: Senila Marin
Published: July 2024

Interest in measuring major and trace elements in plants has increased in recent years because of growing concerns about the elements’ contribution to daily intakes or the health risks posed by ingesting vegetables contaminated by potentially toxic elements. The recent advances in using inductively coupled plasma atomic emission spectrometry (ICP-OES) to measure major and trace elements in plant samples are reviewed in the present work. The sample preparation before instrumental determination and the main advantages and limitations of ICP-OES are described. New trends in element extraction in liquid solutions using fewer toxic solvents and microextractions are observed in recently published literature. Even though ICP-OES is a well-established and routine technique, recent innovations to increase its performance have been found. Validated methods are needed to ensure the obtaining of reliable results. Much research has focused on assessing principal figures of merit, such as limits of detection, quantification, selectivity, working ranges, precision in terms of repeatability and reproducibility, and accuracy through spiked samples or certified reference materials analysis. According to the published literature, the ICP-OES technique, 50 years after the release of the first commercially available equipment, remains a powerful and highly recommended tool for element determination on a wide range of concentrations.
Adsorption on a Spherical Colloidal Particle from a Mixture of Nanoparticles with Competing Interactions
Authors: Litniewski Marek , Góźdź Wojciech T. , Ciach Alina
Published: July 2024

Adsorption of nanoparticles on a spherical colloidal particle is studied by molecular dynamics simulations. We consider a generic model for a mixture of nanoparticles with energetically favored self-assembly into alternating layers of the two components. When both components are attracted to the colloidal particle, the adsorbed nanoparticles self-assemble either into alternating parallel tori and clusters at the two poles of the colloidal particle, or into alternating spirals wrapped around the spherical surface. The long-lived metastable states obtained in simulations follow from the spherical shape of the adsorbing surface and the requirement that the neighboring chains of the nanoparticles are composed of different components. A geometrical construction leading to all such patterns is presented. When the second component particles are repelled from the colloidal particle and the attraction of the first component is strong, the attracted particles form a monolayer at the surface of the colloidal particle that screens the repulsion of the second component. The subsequent adsorbed alternating spherical layers of the two components form together a thick shell. This structure leads to the adsorption that is larger than in the case of the same attraction of the two components to the colloidal particle.
Mass Spectrum of Noncharmed and Charmed Meson States in Extended Linear-Sigma Model
Authors: Ahmadov Azar I. , Alshehri Azzah A. , Tawfik Abdel Nasser
Published: July 2024

The mass spectrum of different meson particles is generated using an effective Lagrangian of the extended linear-sigma model (eLSM) for scalar and pseudoscalar meson fields and quark flavors, up, down, strange, and charm. Analytical formulas for the masses of scalar, pseudoscalar, vector, and axialvector meson states are derived assuming global chiral symmetry. The various eLSM parameters are analytically deduced and numerically computed. This enables accurate estimations of the masses of sixteen noncharmed and thirteen charmed meson states at vanishing temperature. The comparison of these results to a recent compilation of the particle data group (PDG) allows us to draw the conclusion that the masses of sixteen noncharmed and thirteen charmed meson states calculated in the eLSM are in good agreement with the PDG. This shows that the eLSM, with its configurations and parameters, is an effective theoretical framework for determining the mass spectra of various noncharmed and charmed meson states, particularly at vanishing temperature.

Published: July 2024

Pneumonia stands as the leading infectious cause of childhood mortality annually, underscoring its significant impact on pediatric health. Although dexamethasone (DXMS) is effective for treating pulmonary inflammation, its therapeutic potential is compromised by systemic side effects and suboptimal carrier systems. To address this issue, the current study introduces solid lipid nanoparticles encapsulating hydrophobic dexamethasone palmitate (DXMS-Pal-SLNs) as an anti-inflammatory nanoplatform to treat pneumonia. The specialized nanoparticle formulation is characterized by high drug loading efficiency, low drug leakage and excellent colloidal stability in particular during nebulization and is proficiently designed to target alveolar macrophages in deep lung regions via local delivery with the nebulization administration. In vitro analyses revealed substantial reductions in the secretions of tumor necrosis factor-α and interleukin-6 from alveolar macrophages, highlighting the potential efficacy of DXMS-Pal-SLNs in alleviating pneumonia-related inflammation. Similarly, in vivo experiments showed a significant reduction in the levels of these cytokines in the lungs of mice experiencing lipopolysaccharide-induced pulmonary inflammation after the administration of DXMS-Pal-SLNs via nebulization. Furthermore, the study demonstrated that DXMS-Pal-SLNs effectively control acute infections without causing pulmonary infiltration or excessive recruitment of immunocytes in lung tissues. These findings highlight the potential of nebulized DXMS-Pal-SLNs as a promising therapeutic strategy for mitigating pneumonia-related inflammations.
Forecasting End-of-Life Vehicle Generation in the EU-27: A Hybrid LSTM-Based Forecasting and Grey Systems Theory-Based Backcasting Approach
Authors: Karagoz Selman
Published: July 2024

End-of-life vehicle (ELV) forecasting constitutes a crucial aspect of sustainable waste management and resource allocation strategies. While the existing literature predominantly employs time-series forecasting and machine learning methodologies, a dearth of studies leveraging deep learning techniques, particularly Long Short-Term Memory (LSTM) networks, is evident. Moreover, the focus on localized contexts within national or municipal boundaries overlooks the imperative of addressing ELV generation dynamics at an international scale, particularly within entities such as the EU-27. Furthermore, the absence of methodologies to reconcile missing historical data presents a significant limitation in forecasting accuracy. In response to these critical gaps, this study proposes a pioneering framework that integrates grey systems theory (GST)-based backcasting with LSTM-based deep learning methodologies for forecasting ELV generation within the EU until 2040. By introducing this innovative approach, this study not only extends the methodological repertoire within the field but also enhances the applicability of findings to supranational regulatory frameworks. Moreover, the incorporation of backcasting techniques addresses data limitations, ensuring more robust and accurate forecasting outcomes. The results indicate an anticipated decline in the recovery and recycling of ELVs, underscoring the urgent need for intervention by policymakers and stakeholders in the waste management sector. Through these contributions, this study enriches our understanding of ELV generation dynamics and facilitates informed decision-making processes in environmental sustainability and resource management domains.
Double Percolation of Poly(lactic acid)/Low-Density Polyethylene/Carbon Nanotube (PLA/LDPE/CNT) Composites for Force-Sensor Application: Impact of Preferential Localization and Mixing Sequence

Published: July 2024

This study explores the enhancement of electrical conductivity in polymer composites by incorporating carbon nanotubes (CNTs) into a co-continuous poly(lactic acid)/low-density polyethylene (PLA/LDPE) blend, creating a double percolation structure. Theoretical thermodynamic predictions indicate that CNTs preferentially localize in the LDPE phase. The percolation threshold of CNTs in the PLA/LDPE/CNT composites was 0.208 vol% (5.56 wt%), an 80% reduction compared to the LDPE/CNT composite, due to the double percolation structure. This thermodynamic migration of CNTs from PLA to LDPE significantly enhanced conductivity, achieving a 13.8-fold increase at a 7.5 wt% CNT loading compared to the LDPE/CNT composite. The localization of CNTs was driven by thermodynamic, kinetic, and rheological factors, with viscosity differences between PLA and LDPE causing dense CNT aggregation in LDPE. Initial contact of CNTs with PLA reduced aggregation, allowing PLA to infiltrate CNT aggregates during melt-mixing, which influenced the final morphology and electrical conductivity. These findings provide new insights into the fabrication of conductive polymer composites for force sensor applications.

Published: July 2024

An 80-year-old man presented to the cardiology outpatient clinic due to shortness of breath. His past medical history included alcohol intake, hypertension, inferior wall myocardial infarction (five years ago), an ischemic stroke, and permanent atrial fibrillation (diagnosed three years before the current examination). A physical exam revealed a decreased intensity of S1 and S2, irregular rate and rhythm, and no murmurs nor friction rub. X-rays, Computed Tomography, and echocardiography exhibited pericardial calcification, involving mostly the inferior wall and protruding into the left ventricle. A diagnosis of constrictive pericarditis due to pericardial calcification was established and considered idiopathic. Even when it may be related to ischemic heart disease, post-infarction pericarditis could explain how the calcification extended to adjacent territory perfused by the circumflex coronary artery. Combined imaging studies were crucial not only for identifying calcium deposits in the pericardium but also in assessing a patient inherently prone to co-existing and exacerbating conditions. Even though pericardiectomy allows for removal of the clinical manifestations of congestive pericarditis in the most symptomatic patients with pericardial calcification, among patients like ours, with tolerable symptoms, cardiologists should discuss the therapeutic options considering the patient’s choices, potentially including a rehabilitation plan as part of non-pharmacological management.

Published: July 2024

Electric vehicles (EVs) encounter substantial obstacles in effectively managing energy, particularly when faced with varied driving circumstances and surrounding factors. This study aims to evaluate the performance of three different control systems in a fully operational hybrid energy storage system (HESS) installed in the Nissan Leaf. The objective is to improve the performance of EVs by focusing on optimising energy management in response to different global environmental and driving circumstances. This study utilises an analytical strategy by developing a distinct energy management system model using MATLAB/Simulink. This model is specifically designed for optimising the integration and control of batteries and supercapacitors (SCs) in a fully active HESS. This model mimics the performance of the controllers under three different driving cycles—Artemis rural, Artemis motorway, and US06. The findings demonstrate notable progress in managing the battery state of charge (SOC) and the system’s responsiveness, especially when employing the radial basis function (RBF) controller. This study emphasises the capacity of HESSs to enhance the effectiveness and durability of EVs, therefore promoting wider acceptance and progress in electric transportation technology.
A New Model of a Macular Buckle and a Refined Surgical Technique for the Treatment of Myopic Traction Maculopathy
Authors: Parolini Barbara
Published: July 2024

Myopic traction maculopathy (MTM) affects 20% of eyes with pathologic myopia (PM). The MTM Staging System (MSS), published in 2020, describes the nomenclature of MTM as well as a proposal of pathogenesis, natural evolution, and prognosis. A study of customized treatment for each stage of MTM has been published previously and suggested to treat maculoschisis and detachment by placing a macular buckle (MB) behind the macula to push the sclera towards the retina, selecting pars plana vitrectomy (PPV) only in cases where a macular hole is associated with MTM. We hereby describe a new model of a macular buckle, known as NPB, and an NPB loading device, with the aim to standardize the surgical technique and render it more user friendly, efficient, and safe. Macular buckle is an effective and safe procedure to treat maculoschisis and macular detachment in MTM. We recommend using it as a unique and first-line treatment.

Published: July 2024

Relevance. Myofascial pain syndrome (MPS) often progresses to a chronic form that is challenging to treat with established methods. This issue is well known to dentists and frequently leads to frustration despite significant efforts to advance knowledge in the fields of etiopathogenesis, diagnosis, and therapy. Most treatment protocols focus on normalizing physiological parameters, such as restoring masticatory function, achieving stable occlusal relationships, alleviating pain, and enhancing the psychological well-being of these patients. Therefore, the need for non-invasive diagnostics to assess functional activity and monitor the condition of masticatory muscles during treatment is crucial. This study aims to address this need.

Materials and methods. The examination and treatment of 64 patients with myofascial pain syndrome were conducted in two stages—clinical and electromyographic. During the clinical examination, tenderness of the masticatory muscles during palpation and the degree of mouth opening were assessed. The electromyographic research was also conducted in two stages. The first stage assessed the average amplitude and total biopotential of the masticatory and temporal muscles on both the right and left sides. The second stage evaluated the symmetry index of the masticatory muscles, as well as torsion and masseter indices. The first group received conventional treatment combined with laser therapy, while the second group received ozone therapy and kinesiology taping in addition to the conventional therapy.

Results. In the short-term observations over 14 days, both groups achieved positive results. However, patients undergoing ozone therapy and kinesiology taping showed statistically significant improvements in their parameters by the third day of observation compared to their baseline values.

Conclusion. For diagnosing this pathology, it is advisable to incorporate electromyography into the examination protocol to allow non-invasive evaluation of the functional activity of the masticatory muscles. For treating myofascial pain syndrome, minimally invasive methods with anti-inflammatory, analgesic, and muscle relaxant effects are recommended. While all treatment methods yielded favorable results, ozone therapy combined with kinesiology taping effectively eliminated both subjective and objective symptoms in this patient category.

Published: July 2024

Background: Maternal age influenced the quantity and quality of oocytes. The composition of follicular fluid was changed in advanced maternal age. This study was conducted to evaluate changes in redox potential and blastocyst formation potential in older women.

Methods and materials: Retrospective study collected data from December 2020 to October 2023 on patients treated with in vitro fertilization with follicular fluid surveyed at the Center for Reproductive Endocrinology and Infertility (HUECREI), Hue University of Medicine and Pharmacy, Hue.

Results: Two cohorts comprised the 456 patients: Group 1, consisting of individuals younger than 35 years of age, and Group 2, comprising those 35 years or older. Anti-Müllerian hormone (AMH), initial follicle-stimulating hormone (FSH), and total FSH dose utilized differed significantly between Groups 1 and 2, with median values of 3.79 versus 2.10 ng/mL (P value < 0.001), 225.00 versus 277.50 IU/L (P value < 0.001), and 2025.00 versus 2325.00 IU/L (P value < 0.001), respectively. However, there were no significant differences in ORP, maturation rate, fertilization rate, or blastocyst formation rate between the two age groups. Variations in ORP were only observed among subgroups of patients with the ability to achieve an expected fertilization rate of ≥ 70% in Group 1. Specifically, the subgroup meeting expectations had a lower ORP of 83.00 ± 83.00 mV, in contrast to the non-expectation group which had an ORP of 96.14 ± 83.00 mV, accompanied by a P value of 0.005. The difference of ORP was not observed in the group that reached and did not reach the benchmark embryo formation ≥ 60% in the two age groups.

Conclusion: Advanced maternal age have declined in ovarian function but no statistically significant difference in redox potential in follicular fluid has been observed. The fertilization rate and blastocyst formation rate were equivalent across the two age groups of women. The redox potential of follicular fluid was not statistically significant difference between cycles that reached and did not reach the benchmark of blastocyst formation ≥ 60% in the two age groups of women.

Key words: Blastocyst, advanced maternal age, oxidative-reduction potential (ORP), in vitro fertilization.

A cirurgia plástica é uma abordagem cirúrgica bastante realizadas por apresentar um vasto campo de atuação na estética, reconstrução ou reparação. Nesse campo, a plástica de abdome objetiva sanar insatisfações estéticas, reparar deformidades anatômicas abdominais e promover saúde. Portanto, objetivou-se correlacionar as proteínas de fase aguda (PCR, Albumina), com o Índice de Proteína C-reativa/Albumina, com o grau de risco cirúrgico e realizar avaliação morfológica da cicatriz relatando as dificuldades encontradas na realização da plástica de abdome em um hospital público de Teresina – PI. Tratou-se de um estudo de campo de caráter longitudinal e prospectivo. Todos os 9 pacientes pertenciam ao sexo feminino (100%), com média de idade de 41,11 ± 7,97 anos, e cor parda (55,6%). O peso corporal variou de 50 a 108 Kg, e o IMC de 22 a 42 Kg/m2. Cerca de 44,4% foram classificadas com peso normal, e 33,3% com sobrepeso. Dentre as 9 pacientes avaliadas, apenas 6 apresentaram exames satisfatórios para realização da cirurgia. Destas, apenas 2 realizaram a dermolipectomia de abdome em tempo hábil para defesa deste trabalho. Correlacionando as proteínas de fase aguda (PCR, Albumina) nas primeiras 24 horas de pós-operatório, com o Índice de Proteína C-reativa/Albumina (PCR/Alb) e com o grau de risco cirúrgico das duas pacientes, identificou-se um médio risco em relação ao prognóstico infamatório para a paciente A e alto risco para a paciente F. No pós-operatório, a paciente A evoluiu sem complicações e a paciente F teve complicações que foram manejadas ambulatorialmente e resolvidas sem demais alterações clínicas.

Os casos de dengue relatados atualmente têm sido significativos, demandando ações e políticas que visem minimizar a doença, o que pode ser obtido a partir da eliminação dos focos de dengue e criadouros do mosquito. Para este fim, a participação da comunidade é de grande importância de modo que os profissionais de saúde precisam elaborar propostas que promovam a educação da comunidade no que tange à prevenção e eliminação dos focos da doença. Uma das possibilidades de se realizar ações educativas da comunidade são as intervenções nas escolas. Sendo assim, este artigo tem como objetivo apresentar um relato de experiência vivenciado por nove alunos do 3º período do curso de medicina da Fundação Educacional de Penápolis (Funepe), durante as práticas da disciplina extensionistas realizada na Escola Municipal Aldofo Hecht, em Braúna, no interior do estado de São Paulo, em que foram feitas intervenções de forma lúdica sobre a importância do combate ao mosquito, a partir dos cuidados com os ambientes em casa e na comunidade. Foram realizadas palestras, atividades e brincadeiras em uma escola municipal, para um grupo de aproximadamente 200 crianças, professores e funcionários. A atividade realizada favoreceu a aprendizagem do grupo de universitários, aproximando-os do cotidiano dos cuidados em saúde junto à comunidade.

Introdução: a crescente preocupação com doenças emergentes, causadas por patógenos virais humanos, especialmente as arboviroses como Dengue, Zika e Chikungunya, tem destacado o papel crítico do vírus Oropouche (OROV) como diagnóstico diferencial, devido a sua propensão de desencadear epidemias, especialmente em regiões tropicais e subtropicais. Embora seja a segunda arbovirose mais prevalente no Brasil, logo atrás da Dengue, estudos existentes sobre o OROV são escassos até o momento atual. Objetivo: destacar a Febre Oropouche como um importante diagnóstico diferencial entre as demais arboviroses e salientar a necessidade de conduzir novos estudos na vigilância e no controle desta doença emergente. Metodologia: revisão integrativa da literatura, utilizando-se as bases de dados PubMed, Scielo e Lilacs. Os critérios de inclusão foram artigos originais produzidos nos últimos 10 anos abrangendo à epidemiologia, fisiopatologia, manifestações clínicas, diagnóstico e manejo das arboviroses, incluindo a Febre Oropouche. Discussão: as arboviroses constituem uma importante questão de saúde pública pela sua rápida propagação, presença disseminada de vetores e  ausência de terapias definitivas. A complexidade da Febre Oropouche como um diagnóstico diferencial entre Dengue, Zika e Chikungunya cria uma camada adicional de desafio ao controle e tratamento de tais enfermidades. Conclusão: a Febre Oropouche representa um desafio de suma importância para a saúde pública, exigindo uma abordagem multidisciplinar para prevenção, diagnóstico e controle. O desenvolvimento de novos estudos em busca de uma compreensão aprofundada desta arbovirose é imprescindível para o investimento em vacinas e medidas preventivas para controlar sua disseminação.

Introdução: O Brasil é um país de proporções continentais, cuja população apresenta elevado grau de miscigenação e de ascendência étnica. De acordo com a região geográfica do país, são observados diferentes perfis raciais e dimensões do acesso, que podem justificar as diferenças nos desfechos clínicos associados à neoplasia mamária. Objetivo: descrever a mortalidade por esta neoplasia entre as diferentes raças - preta, branca, parda, amarela e indígena, no período de 2018 a 2022. Metodologia: Trata-se de um estudo observacional transversal, descritivo, através do levantamento de dados epidemiológicos. As informações epidemiológicas e de morbidade, bem como as estatísticas vitais e a mortalidade foram obtidas no Departamento de Informática do Sistema Único de Saúde (DATASUS). Resultados: Destaca-se notável prevalência da raça parda ao analisar os óbitos por câncer de mama no período de 2018-2022, contabilizando 57% dos casos. No que diz respeito ao sexo, houve prevalência no gênero feminino, totalizando 98% das notificações. Quanto ao estado civil, observou-se o predomínio em solteiros, representando 30,6% dos casos. Conclusão: Conclui-se que os óbitos variam significativamente entre grupos raciais. A predominância da raça parda no sexo feminino, em mulheres com mais de 50 anos e solteiras, demonstra a complexidade das disparidades de saúde dentro do contexto étnico e social variado, as quais ressaltam a necessidade de abordagens e políticas de saúde pública para atenuar as diferenças e melhorar os desfechos para todos os grupos afetados.
