Published: October 2024

Skin aging leads to reduced structural integrity and reduced skin function. Medicinal plant extracts that have antioxidant properties and are able to inhibit tyrosinase have become a trend in various uses for anti-aging. One of the commonly used plants in traditional medicine that grows in many Asian countries is garcinia cowa. Currently, no one has studied the fruit from two different aspects, namely for the skin and to help in physical improvement. The purpose of this study is to test the phenolic content, antioxidants, and tyrosinase inhibition activity of the extract from the skin and pulp of garcinia cowa as well as its effectiveness on the physical ability and function of the skin. The stages carried out start from the collection of garcina cowa fruits, the determination of total phenolic levels, the determination of antioxidant activity, and the determination of tyrosinase inhibition activity. The total phenolic content was determined by the folin-ciocalteu method. The phenolic content of garcinia cowa fruit peel extract is 17.789 mg of gallic acid equivalent extract (GAE)/g, while the meat extract is 12.078 mg GAE/g extract. Furthermore, the flesh of garcinia cowa showed weak antioxidant activity with an IC50 value of 490.2 μg/mL, but the fruit peel extract showed moderate antioxidant activity at 243.3 μg/mL. The skin of garcinia cowa fruit shows tyrosinase inhibition activity in vitro, which is more significant than the pulp. Garcinia cowa peel and pulp extracts both contain phenolic compounds and show the antioxidant activity, but it was found that the fruit peel extract has a higher content. This means that with its antioxidant content, it can ward off free radicals, prevent cell damage, and reduce the risk of chronic diseases. The combination of phenolic content, antioxidant activity, and tyrosinase inhibitor potential provides significant benefits for skin health and overall physical health.

Authors:   , Gomes Gabriela Santos
Published: October 2024

A presente dissertação apresenta uma pesquisa sobre a atuação do Conselho Tutelar em um município de pequeno porte I, tendo como objetivo discutir sobre contradições, limites e possibilidades desse órgão, demarcando o contexto de neoliberalismo e minimalismo das políticas sociais. Expõe a infância e adolescência como categorias sociais, plurais e históricas, assim como o percurso histórico dos direitos infantojuvenis. Demonstra também o atual paradigma de atendimento à criança e ao adolescente e as expressões do neoliberalismo e do conservadorismo na realidade social. O processo metodológico combinou entrevistas com conselheiras tutelares e profissionais do Sistema de Garantia de Direitos da Criança e do Adolescente (SGDCA) do município, com pesquisa ação-participante, possibilitando aprofundar na realidade do local de estudo. A análise dos dados se pautou nos referenciais do materialismo histórico-dialético, que conduz a uma interpretação dinâmica e totalizante da realidade, considerando os componentes históricos, sociais, econômicos e políticos dos fenômenos. A pesquisa demonstra que o Conselho Tutelar, enquanto instituição comunitária e de controle social, tem encontrado dificuldades para se afirmar nessa perspectiva, pois sofre os efeitos da formação sócio-histórica do Brasil e da ofensiva neoliberal. Os resultados também indicaram que a capacitação profissional é o elemento central no debate sobre o referido órgão.

Neste trabalho avaliou-se a densidade populacional dos besouros polinizadores do gênero Elaeidobius em meio a sua relação com os índices pluviométricos em diferentes arranjos de plantios da palma de óleo (cultivos interligados e isolados). O trabalho foi conduzido em plantio comercial nos municípios de Tailândia e Moju, nordeste paraense, com dados obtidos de 2018 a 2022. Os resultados mostraram que a população dos principais besouros polinizadores da palma de óleo é influenciada pelos índices pluviométricos ao longo do ano induzindo-os a baixos níveis nos períodos mais chuvosos. Podemos concluir que a população dos besouros do gênero Elaeidobius é influenciada pela elevação dos índices pluviométricos, induzindo a sua redução populacional e quando as áreas de palma de óleo são não contíguas o restabelecimento desta população é prejudicada por não haver a livre circulação dos besouros entre os plantios.

Authors:   USA, Majumdar Ananth
Published: October 2024

In distributed systems, maintaining consistency across multiple caches presents a significant challenge, often leading to data inconsistencies and degraded application performance. This paper proposes and evaluates a novel approach to cache synchronization using Amazon Web Services (AWS) Simple Notification Service (SNS) and Simple Queue Service (SQS). The proposed system leverages the pub-sub model of SNS combined with the reliable message queuing of SQS to create a scalable and robust cache synchronization mechanism. We present the architecture, implementation details, and performance analysis of this system, demonstrating significant reductions in database load and improvements in response times while ensuring eventual consistency across distributed caches. Comparative analysis with alternative solutions highlights the advantages of the SNS/SQS approach in terms of scalability, reliability, and ease of implementation. This research contributes to the field of distributed systems by offering a practical, cloud-native solution to the cache synchronization problem, applicable to a wide range of applications requiring consistent data across multiple instances or services.

Authors: Muhammad Ukasha , Damola Gbolagade Morufat
Published: October 2024

Background: With their volatile prices, cryptocurrencies have become valuable assets in the financial market. Predicting cryptocurrency prices accurately is essential for making well-informed investment decisions. Time series prediction models, like Gated Recurrent Unit (GRU) and Recurrent Neural Networks (RNN), are popular tools for financial data forecasting because they can capture sequential dependencies in data. Aim: This study aims to predict the average monthly closing prices of five major cryptocurrencies—Bitcoin (BTC), Ethereum (ETH), Binance Coin (BNB), Litecoin (LTC), and Ripple (XRP)—using GRU and RNN models and evaluate their performance in forecasting these prices. Method: Time series input sequences were produced and historical price data for the chosen cryptocurrencies were preprocessed using Min-Max Scaling. This data was divided into training and test sets, and it was used to train both the GRU and RNN models. The Mean Absolute Percentage Error (MAPE) and Root Mean Squared Error (RMSE) were used to assess the performance of the model. Results: For the majority of cryptocurrencies, the RNN model exhibited better predicted accuracy and consistently outperformed the GRU model. For instance, the RMSE for Ripple was 0.06 for the RNN model and 0.09 for GRU. In a similar vein, the RNN model outperformed the GRU model with a MAPE of 12.97% for Ethereum. These results imply that RNN models are more suitable for financial forecasting in this sector, as they yield more accurate predictions for cryptocurrency values.

Published: October 2024

Background: In biometrics, one of the most popular study topics is the detection of face morphing attacks. However, because present methods are unable to capture significant feature changes, they are unable to strike the correct balance between accuracy and complexity. Survey investigation and analysis have shown that the existing method of face morphing detection take a bit longer time to detect the image attack due to the high computation required by facial feature extraction approaches. Conversely, further study is needed to develop a model to enhance the computational time and accuracy of the current face morphing recognition methods. The paper developed a hybrid model for face morphing detection. The FERET database was created to aid in the evaluation and development of algorithms. Local Binary Pattern (LBP) was used as feature extraction algorithm and Residue Number System (RNS) was introduced to reduce the lengthy computational time of LBP during the extraction of images. The classification accuracy of 98% was achieved for the FERET database, while an accuracy of 96% was achieved for the FRGCv2 database. An average training time of 0.0532seconds was recorded for the FERET database, while an average training time of 0.0582seconds was achieved for the FRGCv2 database. The study concluded that the high dimensionality of LBP was well reduced and optimized by the RNS algorithm, which improved the performance of face morphing recognition.

Published: October 2024

While smart farming is becoming increasingly popular as a way to improve the efficiency and sustainability of agroecosystems and global food security, its vulnerability to cyber-attacks is rapidly increasing. A distributed reputation system can help detect and prevent malicious activities by tracking the reputation of IP addresses of devices, products, and entities in a smart farming system, thereby enhancing its security and trust. In this paper, we propose a blockchain-based reputation system for IP addresses in smart farms for real-time intrusion detection and prevention. The study uses the Ethereum blockchain smart contracts, Oracles, Intrusion Detection System (IDS), and a Proof-of-Reputation (PoR) consensus mechanism. The system was evaluated on two datasets, the Spamhaus Blocklist, and the Malware Domain List datasets. It achieved high accuracy, recall, and precision rates, F1 score, as well as low false positive and false negative rates. This shows that the proposed system has high potential to be an effective tool for improving malware detection and prevention in real-time, creating a trusted supply chain for a smart farming ecosystem against a wide range of attack types, including denial-of-service attacks, probe attacks, and user-to-root attacks.

Published: October 2024

Fraudulent transactions have long been a challenge in the banking industry, causing significant financial losses and operational burdens. Traditional fraud detection systems often struggle to adapt and respond in real-time to the evolving tactics of fraud. This study aims to develop a digital twin and IoT-enabled online learning model for real-time monitoring and control of fraudulent transactions in banking. The proposed system integrates digital twin technology and IoT sensors to create a virtual replica of transaction environments, enabling continuous learning and adaptation using an online learning model. Performance metrics such as detection speed, prediction accuracy, precision, recall, and F1 score were used to evaluate the system. The system was tested using a dataset of banking transactions, including legitimate and fraudulent activities. Key results include detecting fraudulent transactions 40% faster than traditional methods, reducing detection time from 5 minutes to 3 minutes. The model achieved an accuracy of 92%, an 8.24% improvement over traditional fraud detection systems. The false positive rate was reduced by 28%, meaning fewer legitimate transactions were wrongly flagged as fraudulent. Precision increased by 5.95%, reaching 89%, and recall improved by 8.75%, reaching 87%. This led to a 7.32% increase in the F1 score, reaching 88%. The system offers enhanced real-time fraud detection capabilities, reducing false positives and improving overall security and operational efficiency in the banking industry.

Published: October 2024

This study investigated the effect of taxation policies on the profitability of deposit money banks in Nigeria. The ex-post facto research design was employed to assess the effects over the period 2013 to 2022. The sample size comprised five major Nigerian banks (Zenith Bank, Access Bank, UBA, FCMB, and Fidelity Bank) selected using a non-probability sampling technique. Data were sourced from published audited financial statements available on bank websites, the Nigerian Stock Exchange, and the Federal Inland Revenue Service. Variables included ROA as the dependent variable, and Corporate Income Tax (CIT), Value-Added Tax (VAT), and Withholding Tax (WHT) as independent variables. The study employed panel data Ordinary Least Square (OLS) regression on EViews version 12 for analysis. The results indicated that a higher Corporate Income Tax (CIT) rate, with a coefficient of -0.903132 and a p-value of 0.0000, had a significant and negative effect on bank profitability. In contrast, Value Added Tax (VAT) exhibited a coefficient of 0.287309 with a non-significant p-value of 0.6276. However, Withholding Tax (WHT), with a coefficient of -3.286051 and a p-value of 0.0200, significantly reduced bank profitability. The study concluded that CIT and WHT policies directly influenced bank profitability, underscoring the need for balanced tax policy decisions. VAT showed no direct effect due to the indirect intermediary role of banks. Recommendations include reviewing CIT and WHT policies concerning the banking sector, ensuring VAT policy transparency, and considering incentives or exemptions to maintain industry stability. The study contributed by emphasizing tax policy effects on the financial sector and informed balanced taxation approaches.

Published: October 2024

Introduction: Time away from training and competition from sport injuries may lead to detrimental effects on muscle strength and endurance. The cross-education effect plays an important role in preserving strength during recovery and rehabilitation; however, the effects have been found to be inconclusive. In addition, the distinct impacts of eccentric and concentric strengthening exercises need to be explored. The objective of this study was to compare the cross-education effects of eccentric and concentric wrist flexor strengthening exercises on hand grip strength among recreational athletes. Methods: A total of 39 recreational athletes aged between 18-25 years old were randomly assigned into two groups of wrist flexor strengthening exercise: eccentric (ECC) and concentric (CON) training groups. The training period for the study was 4 weeks with 3 sessions of strengthening exercises per week. Handgrip strength was measured bilaterally, before and after the intervention using the JAMAR handgrip dynamometer. Results: Significant increases in hand grip strength were observed for the ECC and CON groups in both the trained and untrained hands following 4 weeks of training. However, the handgrip strength between the two groups in the untrained hand was not significantly different (p=0.64). The strength gain in the untrained hand was 9.8% and 10.8%, for ECC and CON groups, respectively. Conclusion: The cross-education effect was significant in improving strength in the untrained hand. There was no difference in strength gains between concentric and eccentric strength training.

Authors: Khadka Bivishika , Kashyap Divya , Sandilya Abhishek Kumar , Verma Vishal
Published: October 2024

BackgroundNeck discomfort is a frequent problem that can impair quality of life and make it difficult to perform daily tasks. Pain from neck strain is not limited to the cervical spine; it can also radiate into the skull and result in a headache of cervical origin, known as cervicogenic headache. Craniosacral can cure a wide array of musculoskeletal and neurological conditions, including headaches, but there is little evidence in the literature of its efficacy, particularly regarding cervicogenic headaches.ObjectiveTo determine the effectiveness of craniosacral therapy (CST) for cervicogenic headache and improve our understanding of cervicogenic headache.MethodsA review of the literature was performed using the following electronic search bases: PubMed, Google Scholar, Scopus and The Cochrane library. To perform the search, these MeSH terms were used: “Cervicogenic headache” AND “Neck pain” AND “Craniosacral therapy” AND ‘Headache’ between the date 2020 to 2022.ResultsEleven articles were included in the literature review. Overall, the results of published articles indicate 97.5–100% of the patients thought the treatment program was satisfactory. No adverse effects were reported. It has been demonstrated that CST is particularly safe and effective in lowering the intensity of neck pain. It may also enhance the quality of life and functional impairment for up to three months following the intervention. In addition to the conventional medical therapy, CST may be a beneficial therapeutic option for persistent and recurrent neck discomfort.ConclusionThis review shows that CST is very effective for the treatment of cervicogenic headaches. CST evaluation is feasible in randomized controlled trials and may offer insightful results to enhance therapeutic decision-making.
SHOULD ANTI-CGRP MONOCLONAL ANTIBODIES ALWAYS BE THE DRUG OF FIRST CHOICE FOR MIGRAINE PROPHYLAXIS IN BRAZIL? - A PHARMACOECONOMIC STUDY
Authors: Pelliciari Davy Henrique Sousa , Reis Caio Ricco Alves , Bordini Carlos Alberto
Published: October 2024

Efficacy (success of therapy under ideal conditions), efficiency (the relationship between the costs and outcomes of a specific intervention), and effectiveness (the balance between efficacy and efficiency in clinical practice) are measures used to evaluate health interventions. Thus, in private practice and the public health system, the knowledge of these pharmacoeconomic data should influence the appropriate treatment choice. Migraine prophylaxis falls within this context. Traditional medications are available in the public health system, while galcanezumab is not routinely available. The present study aims to analyze the efficacy and effectiveness of galcanezumab and traditional therapeutic alternatives (amitriptyline, divalproex sodium, and topiramate). Efficacy data were obtained from the relevant literature (PubMed) and cost values from the ABCFARMA magazine. The economic impact analysis considered the cost of living for an economically active adult in Brazil based on the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística, IBGE) and the Institute for Applied Economic Research (Instituto de Pesquisa Econômica Aplicada, IPEA). Efficacy: amitriptyline: 40%; divalproex sodium: 30%; topiramate: 31%; galcanezumab: 50%. Their annual costs were: amitriptyline R$ 240.00; sodium divalproate R$ 876.00; topiramate R$ 600.00; galcanezumab R$ 13,992.00.    Efficiency: amitriptyline 200%; divalproex sodium 41.1%; topiramate 62%; galcanezumab 4%. Ultimately, effectiveness is amitriptyline 120%; divalproex sodium 35.7%; topiramate 46.5%; galcanezumab 27%. Galcanezumab is the most effective; however, in a broader analysis, where payers, availability, and patient conditions are considered, evaluating efficacy alone may not be feasible in practical contexts and, therefore, anti-CGRP antibodies will not always be the first-line medications in migraine prophylaxis.

Published: October 2024

BackgroundThe aims of this study were to analyze the profile of childhood headache complaints in a tertiary headache center, verify the differences between children and adolescents, and provide the clinical characteristics that are related to the headaches.MethodsA review of 384 medical records of children aged between 4-12 years old (n=206) and adolescents (n=178) aged >12 to 18 years old. The variables evaluated were reported as percentages, compared between children and adolescents and selected the variables that were related to headaches diagnosis.ResultsThe majority of the sample were females (60.7%), diagnosis of migraine (70.3%), pulsatile pain (60.2%), episodic attacks (60.2%) and no need for imaging tests associated with the diagnosis (69.3%), which were associated with different clinical characteristics (LR X2(52); p<0.001; Log likelihood = -322.434; Pseud R2 = 0.154). The group of adolescents had a higher proportion of use of antidepressants (29.8%) as prophylactic medication than children, who on the other hand, had a higher prevalence of use of antivertiginous drugs (32%). The abortive medication used was common analgesics (37.8%) and the main outcome after treatment was discharge from the service (32%).ConclusionThe evaluation and the treatment for these patients should take into account the main complaints, considering the particularities of each type of headache and also the age group, in order to identify, treat the disease properly and avoid chronification and continuity in the tertiary service, referring them to less complex services.

Authors: Gonçalves Christian , Kuhn Leonardo josé , Lazari Alan Henrique de , Oliveira Sara Pessoa de , Barboza Bárbara Evelin Gonçalves
Published: October 2024

IntroductionIdiopathic intracranial hypertension (IIH) is marked by elevated intracranial pressure without a known cause, often affecting women of childbearing age and linked to obesity. Diagnosing IIH can be tricky, especially in patients with chronic headaches like migraines. This report discusses a case of IIH in a long-term migraine sufferer, stressing the importance of early detection and effective treatment.Case ReportA 44-year-old woman with migraines since menarche sought medical help in August 2021 due to more frequent and intense headaches, occurring three times a week with light and sound sensitivity and nausea. An MRI in September 2021 showed rare anomalies. Initially treated with topiramate and nortriptyline, her headaches decreased to twice a month by May 2022. However, in November 2022, an ophthalmologist found bilateral papilledema, and she reported retroocular pain and transient visual obscurations. A lumbar puncture confirmed IIH with an opening pressure of 32.5 cmH2O, and she was prescribed acetazolamide. Despite some headache relief, she experienced nausea and visual distortions. Adjustments in her medication and a five-kilogram weight loss improved her symptoms, though issues in the left eye's visual field persisted.CommentThis case highlights the challenges of managing IIH in migraine patients. New headache patterns and visual symptoms were key to suspecting IIH, confirmed by lumbar puncture. Acetazolamide effectively reduced her intracranial pressure, while nortriptyline helped manage sleep issues. Weight loss significantly improved symptoms, emphasizing the need for a multidisciplinary approach between neurologists and ophthalmologists are for optimal care.

Published: October 2024

The semiconductor thin films of Aluminum Silver selenide (AlAgSe2) have been successfully deposited onto FTO glass substrate using electrodeposition method. AgNO3, AlCl3.6H2O and Selenium powder were the precursors used for sources of Ag, Al and Se ions respectively. Prototype of the films were again made and subjected to annealing at temperature of 150°C for 5 minutes to remove the element of moisture content in the as deposited films. The properties of the films such as optical, structural and compositional were investigated using UV-VIS Spectrophotometry, X-ray diffractometry and Rutherford Backscattering Spectroscopy (RBS) analysis respectively to determine the possible areas of applications of the films. Optical analysis revealed that the films have high absorbance in the UV region but decreased in the visible and near infrared regions. The increase in the concentration of selenide ions however decrease the absorbance of the films but annealing tends to increases the absorbance. The films also exhibited very high values of refractive index with minimum value in the order of 2.0 for both the annealed and as deposited samples. The bandgap energies of the films were found to be 1.7 eV, 1.8 eV, 2.2 eV, 2.8 eV and 2.9 eV for as deposited, but decreased to the values of 1.5 eV, 1.6 eV, 1.92 eV, 2.15 eV and 2.5 eV after annealing for the films deposited with 0.1 M, 0.2 M, 0.3 M, 0.4 M and 0.5 M Se ions respectively. The structural analysis indicates that AlAgSe2 films are crystalline in nature with most preferential crystalline plane of (112). The RBS compositional analysis showed that the deposited thin films are rich in silver content. These properties exhibited by the deposited thin films of AlAgSe2 are desirable for photovoltaic devices and for many other optical and optoelectronic applications.

Published: October 2024

This study examines the mentoring strategies used to develop Christian leadership within the Pentecostal Assemblies of God (PAG) Church in Turkana Region, Kenya. Mentoring, rooted in biblical principles such as discipleship, plays a vital role in shaping church leaders, particularly in regions like Turkana, which face socio-cultural and geographical challenges. The study identifies key mentoring models, including spiritual guidance, role modeling, and group mentoring, and assesses their effectiveness in leadership development. Challenges such as geographical isolation, limited educational resources, and cultural factors were also explored to understand their impact on mentoring practices. A descriptive survey design was utilized, targeting 143 church leaders within various PAG districts. Using stratified random sampling, a sample of 59 leaders participated in the study. Data collection was conducted through structured questionnaires and interviews, and the data were analyzed both quantitatively, using descriptive statistics, and qualitatively, through thematic analysis. The findings revealed that spiritual guidance and role modeling are highly valued as mentoring strategies. However, peer mentoring and social support were moderately recognized, suggesting underutilization in some leadership contexts. Notably, gaps in formal mentoring structures were identified, along with a limited understanding of more advanced mentoring techniques such as coaching and sponsorship. The study recommended the implementation of more structured and comprehensive mentoring frameworks, along with enhanced mentor training programs to address these gaps. By addressing these challenges, the PAG Church can improve its leadership development strategies, ultimately fostering a more inclusive and effective mentoring environment.

Acute respiratory distress syndrome(ARDS) is a critical condition which compromises with the respiratory functions.Aim of this study is to present the management of ARDS case in the emergency department. This is a case report of a patient who was admitted to an emergency department.We did not apply any statistical methods. A 41-year-old female patient with no medical history was admitted to the emergency department as an outpatient with complaints of shortness of breath and palpitations. After a physical examination,it was first though that the patient was simply experiencing an anxiety episode.However oxygen saturation was measured as 35 % and further investigation of the patient revealed ARDS as the cause of these symptoms.Patient was admitted to the ICU unit. Even though anxiety can be common,it can be dangerous to dismiss other clinical and potentially lethal pathologies when searching for the cause of respiratory distress.Physical examination and vital signs should be evaluated together to reach a potential diagnosis.

Mục tiêu: Đánh giá kết quả điều trị thoát vị đĩa đệm cột sống thắt lưng-cùng bằng phẫu thuật lấy thoát vị vi phẫu tại bệnh viện Hữu nghị Việt Đức năm 2023. Đối tượng và phương pháp nghiên cứu: Nghiên cứu mô tả cắt ngang hồi cứu, theo dõi dọc trên nhóm bệnh nhân thoát vị đĩa đệm được phẫu thuật vi phẫu lấy thoát vị đĩa đệm năm 2023 tại Bệnh viện Hữu nghị Việt Đức. Kết quả: Nghiên cứu trên 64 bệnh nhân với tỷ lệ nam/nữ là 1,9/1. Sau phẫu thuật 24 giờ, toàn bộ bệnh nhân có cải thiện về tình trạng đau kiểu rễ thần kinh với VAS trung bình là 1 ± 1,24, đã giảm so với trước mổ (7,6 ± 1,41). Sau khoảng thời gian theo dõi trung bình là 8,1 ± 3,35 tháng, đa số bệnh nhân không còn thấy đau hoặc chỉ còn đau ít (87,5%). Tuy nhiên, VAS đau kiểu rễ trung bình là 1,1 ± 1,35, tăng so với thời điểm sau mổ 24 giờ nhưng vẫn nhỏ hơn đáng kể so với trước mổ, 70,3% bệnh nhân không giảm hoặc giảm ít chức năng cột sống theo thang điểm ODI. Tỷ lệ gặp biến chứng sau mổ là 0%, tỷ lệ thoát vị đĩa đệm tái phát là 3,1%. Kết luận: Điều trị thoát vị đĩa đệm cột sống thắt lưng – cùng bằng phẫu thuật lấy thoát vị vi phẫu đạt kết quả thành công cao. Bệnh nhân sau phẫu thuật được cải thiện tình trạng đau kiểu rễ thần kinh và chức năng cột sống với tỷ lệ gặp biến chứng sau mổ và tỷ lệ thoát vị đĩa đệm tái phát rất thấp. Có mối liên hệ có ý nghĩa thống kê giữa giới tính và nhóm nghề nghiệp với mức độ đau sau mổ 24 giờ. Có sự khác biệt có ý nghĩa thống kê giữa VAS trung bình tại thời điểm theo dõi cuối ở các hình thái thoát vị khác nhau.

Đặt vấn đề: Phẫu thuật điều trị bệnh lý động mạch cảnh đã được ứng dụng từ rất lâu. Phẫu thuật động mạch cảnh nên là lựa chọn đầu tiên trên bệnh nhân có nguy cơ phẫu thuật thấp với nhóm có triệu chứng kèm hẹp 50 – 99%, nhóm không triệu chứng kèm hẹp từ 70 – 99% mẫu nghiên cứu [7]. Có hai phương pháp phẫu thuật gồm bóc nội mạc lộn ngược và vá miếng mạch máu nhân tạo. Theo nghiên cứu Cao P và cộng sự (2000), với cỡ mẫu 1353 trường hợp, so sánh giữa hai phương pháp phẫu thuật bóc nội mạc lộn ngược và phẫu thuật vá miếng vá mạch máu nhân tạo thì không thấy có sự khác biệt về lâu dài khi theo dõi. Tuy nhiên, tỉ lệ tử vong ở giai đoạn theo dõi của phẫu thuật bóc nội mạc lộn ngược thì thấp hơn phẫu thuật vá miếng vá mạch máu nhân tạo, lần lượt chiếm 8.1% và 9.3% mẫu nghiên cứu [6]. Tại bệnh viện Chợ Rẫy chưa có nhiều nghiên cứu về đánh giá kết quả lưu thông mạch máu cảnh lâu dài sau khi phẫu thuật bóc lộn ngược nội mạch động mạch cảnh. Đó chính là lý do mà chúng tôi tiến hành nghiên cứu này. Phương pháp: Hồi cứu mô tả loạt ca. Kết quả: Nghiên cứu có tuổi trung bình 75,4 ± 18,2, nam giới chiếm đa số. Yếu tố rối loạn chuyển hoá lipid và đái tháo đường chiếm tỉ lệ lần lượt 88,9 % và 70,8%. Hầu hết các trường hợp trong nghiên cứu là có biểu hiện triệu chứng lâm sàng, chiếm 76,2%. Tổn thương động mạch dạng hẹp từ 70-90% đường kính lòng mạch là chủ yếu, chiếm 79,8 % mẫu nghiên cứu. Phương pháp gây tê tại chỗ chiếm 57,2%. Hầu hết là không dùng shunt trong quá trình phẫu thuật. Phẫu thuật bóc động mạch cảnh chung phối hợp cảnh trong chiếm tỉ lệ cao, chiếm 89,5%. Thời gian kẹp động mạch cảnh khoảng 18,5 phút và thời gian phẫu thuật trung bình khoảng 54 phút. Tỉ lệ thành công về kỹ thuật đạt 97,9%, tỉ lệ tử vong trong 30 ngày chiếm 2,7%. Ở giai đoạn theo dõi, tỉ lệ lưu thông mạch máu thì đầu chiếm 85,1% mẫu nghiên cứu. Kết luận: Phẫu thuật bóc nội mạc lôn ngược động mạch cảnh có tỉ lệ thành công về kỹ thuật cao, ít biến chứng và tỉ lệ lưu thông mạch máu thì đầu cao ở giai đoạn theo dõi. Do đó, phương pháp này đem lại hiệu quả, an toàn và ít biến chứng.
