Factors Causing Stratocumulus to Deviate from Subtropical High Variability on Seasonal to Interannual Timescales
Authors: Ding Hairu , Stevens Bjorn , Schmidt Hauke
Published: February 2025

Abstract. Stratocumulus (Sc) covers the eastern flanks of maritime subtropical high pressure systems and exerts an influence on the global energy budget comparable to CO2. Previous studies have identified the temperature difference between 700 hPa and the surface as the primary driver of Sc variability. However, the mechanistic linkages between subtropical highs and this critical temperature gradient, which defines lower tropospheric stability, remain unresolved. While subsidence modulates temperatures at 700 hPa and wind-driven cooling affects surface temperatures, the observed decoupling between subtropical high intensity and Sc fraction on seasonal to interannual timescales lacks a mechanical explanation. This study uses reanalysis data to test two hypothesized pathways linking the strength of the subtropical highs to the lower tropospheric stability. Results demonstrate that neither pathway dominates, as correlations between Sc-regime temperatures and subtropical high dynamics exhibit strong regional and temporal dependencies, indicating that correlation does not apply causation. Additionally, Sc-regime conditions do not systematically align with subtropical high variability, highlighting the need for further investigation into the dynamical processes governing temperatures in the lower troposphere.

Authors: Hetland Audun , Hetland Rebecca A. , Skille Tarjei Tveito , Mannberg Andrea
Published: February 2025

Abstract. The interest in understanding the human aspects of avalanche risk mitigation has steadily grown over the past few decades. Between 2001–2011, 11 research papers on decision-making in avalanche terrain were published in peer- reviewed journals. Between 2012–2022, this number rose to 55. These papers have been authored by researchers from various disciplines and publications in journals across different fields. Despite the field's nascent stage, to guide future research, it is pertinent to provide an overview of the insights from the existing research literature. This paper offers a systematic overview of peer-reviewed research on human factors in avalanche decision-making. The overview is based on a systematic literature search covering research published up until the end of 2022. The search was conducted across six databases, including Scopus and Web of Science, using a set of keywords related to avalanche decision-making (e.g., “decision-making,” “backcountry skiing,” “avalanche terrain,” “avalanche accident”). Out of nearly 13 000 articles containing at least one of the key search terms, 70 had a research question related to avalanche decision-making and were published in peer-reviewed academic journals. Additionally, 81 relevant papers were published as ISSW (International Snow Science Workshop) proceedings. We coded all the identified papers based on major and minor research questions, control variables, population covered, and methodology. Twelve concepts described the different research themes (e.g., avalanche accidents, avalanche education, decision-making strategies). Due to a large variation in quality regarding the ISSW papers, we only applied these concepts to the 70 peer-reviewed papers and present them by their main concept. The extracted data from all papers including the ISSW papers can be found at https://osf.io/u9ydm/ (last access: 12 February 2025).

A Europa desistiu de si própria
Authors: Avelãs Nunes António
Published: February 2025

Derrotado o nazi-fascismo, a Europa deveria ter-se organizado como pretendia o General De Gaulle, a Europa do Atlântico aos Urais, a Casa Comum Europeia, a Europa de Lisboa a Vladivostoque, de que outros falaram mais tarde.
Alguém tão insuspeito como Henri Kissinger defendeu, já depois de a Rússia ter iniciado o que designou por operação militar especial, que “a Rússia foi, durante 400 anos, uma parte essencial da Europa”, tendo desempenhado um papel decisivo na salvaguarda dos equilíbrios europeus, tudo aconselhando a Europa a empenhar-se numa “paz a longo prazo com a Rússia.”
Também por essa altura, numa importante entrevista à Der Spiegel, Angela Merkel sublinhou que, até pela sua localização geográfica, a Europa não pode deixar de entender-se politicamente com a Rússia.
Em Portugal, já há muito que Eduardo Lourenço sustentava que “a Rússia faz parte da Europa desde que nasceu, ou, em todo o caso, desde que se converteu à fé ortodoxa.” E, como se estivesse a responder aos desvarios de alguns estadistas e ‘comentadores’ que hoje andam por aí à solta, o filósofo acrescentava: “é lamentável que a Europa pense que está completa sem a Rússia.”
A Europa deveria ter compreendido isto mesmo logo depois da derrota do nazi-fascismo. O mais espantoso é que a atitude não mudou depois do desaparecimento da URSS. Já sem razões para ter medo do comunismo, a Europa deveria ter apostado num tratado de segurança colectiva com a Rússia (acompanhado da dissolução da NATO), complementado com acordos de investimento, de comércio, de cooperação nos planos da ciência e da cultura. Os dirigentes europeus de hoje continuam a ser incapazes de reconhecer os erros históricos cometidos, e, sem darem esse passo, não poderão tomar as decisões que tenham em conta os interesses dos povos da Europa.
Wolfgang Streeck é um dos autores de elevados créditos académicos que insistem hoje na necessidade de se encontrar rapidamente uma solução para a segurança colectiva da Europa que inclua a Rússia, advertindo que, se não se concretizar esta solução, “não haverá nenhum lugar para a soberania ou a autonomia europeia, para uma Europa independente como uma terceira força global.”

Authors: Sano Takashi , Kokudo Shohei
Published: February 2025

The degree of difficulty of specific movements can be considered as movement information that teachers use to guide exercise instruction. The purpose of the present study was to quantify the difficulty of the movements comprising the straddle vault for 3rd and 4th grade elementary school children. A total of 538 children (263 boys, 275 girls from the 3rd and 4th grades participated in this study. Their straddle vault movements were recorded from both the left and front sides of the individuals and scored using an observational evaluation criterion. After confirming the unidimensionality of the items, item difficulty (b) was estimated using item response theory (IRT). Additionally, differential item functioning (DIF) was investigated to determine whether the difficulty varied depending on grade level. The following findings emerged from estimating the difficulty levels using IRT: Movements involving taking off from a stable run-up (b = -4.952 to -1.833) and shifting weight forward (b = -0.610 to -0.048) were classified as low-difficulty. Movements requiring a bouncy take-off (b = 0.131 to 0.360) and stable landing (b = 0.012 to 0.816) were of medium difficulty. Regarding landing, DIF was detected, indicating that this movement was more difficult for 3rd graders than for 4th graders. Movements involving turning rotation (b = 1.026 to 1.309) and landing aggressively (b = 1.152 to 1.806) were categorized as high-difficulty. Dynamic take-off movements were identified as extremely difficult (b = 2.432 to 3.824). In conclusion, it is necessary to develop a teaching program that accounts for the difficulty of these movements and to verify its effectiveness.
MUSCULOSKELETAL INJURIES IN GYMNASTICS: A REVIEW OF EPIDEMIOLOGY, ETIOLOGY, AND ASSOCIATED FACTORS
Authors: Horvat Urša , Salmič Manca , Kozinc Žiga
Published: February 2025

Gymnastics encompasses various disciplines, including artistic gymnastics, rhythmic gymnastics, trampoline gymnastics, acrobatics, aerobic gymnastics, parkour, and gymnastics for all. While there are many differences in characteristics, movement execution, and equipment, all disciplines involve brief and high-intensity movements. Athletes achieve extreme ranges of motion and generate and absorb significant forces while performing gymnastic elements. Consequently, gymnasts are prone to numerous injuries, with frequencies ranging from 0.5 to 9.4 injuries per 1000 hours of athlete exposure. The most common types of gymnastics injuries are sprains and strains. In females, lower limb injuries prevail, whereas males predominantly experience upper limb injuries. Specifically, the ankle, knee, and foot are frequent sites of injury in the lower limb, while the shoulder joint, wrist, and elbow are commonly affected in the upper limb. Spinal and head injuries occur less frequently. Identifying factors associated with injuries is important for their prevention. They can be classified as non-modifiable, potentially modifiable, and modifiable. By addressing the latter two groups of factors, we can contribute to reducing the incidence of injuries. The main intrinsic factors linked to injury onset include age, a rapid growth period, previous injuries, joint laxity and instability, limb asymmetry, abnormal muscle stiffness, stress, fear, and lack of focus, while the main extrinsic factors are early specialization, training volume and duration. Most injuries occur during artistic gymnastics routines, especially during the floor exercise. Although more injuries happen during training sessions, the injury rate is higher during competitions. Furthermore, a higher number of injuries is associated with less experienced coaches and inadequate equipment. Preventive measures for gymnastics injuries revolve around training equipment, and healthcare modifications. Optimal landing technique, balanced workload, and comprehensive rehabilitation are crucial, alongside addressing mental and emotional strain.

Purpose: A "new organ at risk" with characteristics of glandular tissue above the torus tubarius has been accidentally reported on PSMA PET/CT. Based on its location, that "finding" was named "tubarial (salivary) glands". Because the description of a potentially "new" body structure in the 21st century was generating scientific interest and controversy, the current study aimed to verify the presence of these structures in two biological species – humans and canines.
Material/Methods: Tissue blocks were obtained from the torus tubarius of three human and canine cadavers and examined by hematoxylin and eosin, periodic acid Schiff (PAS), and Alcian blue staining. The observed results were analyzed by comparing them to samples of human palatine, parotid, submandibular, sublingual, and small palatine salivary glands, as well as canine tissue samples from the area of torus tubarius.
Results: The dissected areas from the human torus tubarius showed submucosal aggregates of predominantly mucous gland tissue, a low number of serous acini, draining ducts, a capsule and trabeculae with blood vessels penetrating inside. Almost similar findings were observed in the canine samples.
Conclusion: The description of the "tubarial glands" in humans, and confirmed in another biological species, sparked a scientific interest which opened the door to further digging into the thrust area with more evidence from different studies. More research is needed to resolve the controversies about the "tubarial (salivary) glands", formulate a consensus, and establish their place in anatomy and clinical practice.

Purpose: to propose a multidisciplinary approach for early diagnosis and therapy of viral hepatitis C (VHC).
Material/Methods: A prospective cross-sectional study was conducted on epidemiological, demographic, clinical, laboratory and viral characteristics in fifty cases of VHC confirmed with positive anti-HCV (by ELISA). Thirty-eight of the cases were hospitalized in different clinics in Pleven (2017–2018). The remainders were blood-donors for the Regional Center of Transfusion Hematology – Pleven. The genotype of HCV and the viral load had been investigated by Real-Time PCR in the Laboratory of Virology at Military Medical Academy – Sofia.
Results: The most affected age groups were 30-39 years and 60-69 years (24%, respectively); males 69.81% (p<0.05). Surgical interventions, blood infusions and hemodialysis (26.32%, 23.68% and 15.79%, respectively) were at the highest risk for VHC (p>0.05). Thirty hospital patients were with chronic VHC (78.95%) (p<0.05). Clinical symptoms suggestive of viral hepatitis were fatigue (39.47%; OR 5.25), decreased appetite (28.95%; OR 2.16), abdominal discomfort (21.05%; OR 23.33); 52.63% of patients were asymptomatic (p<0.0005). Laboratory investigations revealed slightly or moderately elevated total bilirubin (mean 53.27±37.38 µmol/L; 95% CI 18.48–88.06), ASAT (mean 231.36±155.82 IU/L; 95% CI 79.91–382.80) and ALAT (mean 294.48±196.26 IU/L; 95% CI 96.37–492.59) (p>0.05). All isolates of HCV had been proved to be genotype 1b. The viral load was detectable in 22 samples (range 683–673,720 copies/mL).
Conclusion: VHC is mostly asymptomatic. Screening for anti-HCV in risk groups and genotyping of HCV will reduce nosocomial transmission, facilitate early therapy and prevent complications of infected individuals.

Authors: J. Karthiyayini
Published: February 2025

Personalized recommendations are provided by recommender systems, which help users cope with the issue of information overload. The primary objective of this research paper is to address the issue of information overload by offering personalized tourism recommendations to users. The study proposes using multi-criteria recommendation algorithms that consider many attributes rather than depending exclusively on overall user ratings, as is common in traditional recommender systems. The fundamental concept of this strategy relies on a hybrid filtering technique. In addition, the system employs a bi-directional autoencoder (BDA) model to personalize recommendations based on various visitor profiles. The proposed methodology has evaluated various real-world data obtained from several travel websites. The experimental evaluations have demonstrated its outstanding efficacy in enhancing prediction accuracy when compared to existing algorithms. The proposed approach not only addresses the challenges associated with vast and diverse data but also offers personalized travel plans according to the unique preferences of each visitor, thus enhancing the user experience in tourist recommendation systems.

Moderating Effect of Industry Characteristics on Corporate Governance-Financial Performance Relationship
Authors: Ramakrishna Vuppuluri
Published: February 2025

Corporate Governance (CG) is central to all organizational operations because it has direct implications for financial performance, despite the fact that its effectiveness differs from one industry to another. This study examines how particular CG mechanisms, including the board of directors’ characteristics, ownership structure, and transparency, affect financial performance metrics, such as profitability, return on equity (ROE), and market valuation. The study employed a mixed methods research design, whereby financial data and governance practices from various manufacturing firms, technology firms, service firms, and so on were used. The study confirmed that there is a positive relationship between the level of CG practices and the financial performance of firms in industries that are highly regulated. Moreover, it was not clearly traceable in industries exposed to highly geared volatile markets. On this basis, it can be concluded that there are some specific industry characteristics that act as moderators of the CG-performance link. The study concludes that it is important for every country to adopt a country-specific strategy toward CG to obtain better financial results, which will be useful to policymakers, regulators, and corporate managers who want to achieve sustainable business growth.
A Blockchain Enabled Proxy Re-Encryption Framework for Secure and Low Latency Data Sharing in Fog based IoT Networks
Authors: Peda Narayana Bathula
Published: February 2025

This research introduces FoReChain (Fog-based Re-Encryption Chain), a blockchain-enabled proxy re-encryption (PRE) framework designed for secure, low-latency data sharing in fog-based IoT networks. The framework addresses key challenges related to data security, privacy, and performance in distributed environments, where traditional models face issues like high latency, limited scalability, and inefficient key management. FoReChain integrates blockchain with ECC-based proxy re-encryption to secure data without exposing original content. A delegated Practical Byzantine Fault Tolerance (d-PBFT) consensus mechanism ensures efficient transaction validation. The framework processes data at fog nodes, reducing delays commonly found in cloud-dependent models. Key management relies on time-based key updates stored immutably on the blockchain, while zero-knowledge proofs support secure, anonymous data sharing. The study evaluates FoReChain against FE-PRE and PREA models using metrics such as latency, throughput, scalability, blockchain consensus time, and adaptive policy effectiveness. Results show lower latency, higher throughput, and better adaptability in FoReChain, especially under heavy network conditions like smart healthcare and industrial IoT setups. FoReChain demonstrates secure data sharing, efficient resource utilization, and reliable key management in dynamic IoT environments. It offers consistent performance under varying loads, with improved scalability and data integrity maintained through decentralized validation.

Published: February 2025

Fast data flow designs for processing volumes of data are crucial in the environment of data-driven technologies of today. This work examines closely how to integrate Apache Kafka with RabbitMQ to produce a powerful data flow architecture. Excellent at managing high speed and flexibility, Apache Kafka is a distributed streaming platform. Considered to be simple to use and capable of handling complicated routing, RabbitMQ is message broker tool. Combining both technologies produces a unique system that makes data, handling, and distribution simpler by using the best aspects of each. The first section of the paper contrasts and evaluates Apache Kafka's and RabbitMQ's inherent capabilities. It then looks at how these platforms may be better used together, with an emphasis on circumstances wherein combining them facilitates real-time data processing and guarantees message delivery even in the event of a disaster. The technical component of the integration—that which relates to settings, system configuration, and methods of enhancing speed and dependability—is covered in further depth in this article Examined are case studies from a variety of companies to demonstrate how and why this integrated approach may be practical in the real world. These examples highlight how adaptable and efficient Kafka-RabbitMQ systems are in handling many kinds of data and demands. This research contributes to the area by providing a whole strategy for combined usage of Apache Kafka and RabbitMQ. This will enable businesses to upgrade their systems of data flow. Particularly with regard to enhancing the flow of data and rendering integrated data systems more valuable, the findings clearly highlight areas that need greater research.
SafeLink: End to End Privacy & Integrity for Data Transfer in IoT Applications
Authors: Neve Rahul P.
Published: February 2025

In an era dominated by the Internet of Things (IoT) and ubiquitous connectivity, the demand for securing sensitive data, especially in surveillance systems, is paramount. This paper introduces a novel approach to enhancing security through the deployment of a lightweight cryptographic algorithm. The algorithm is specifically designed for resource-constrained environments, exemplified by its successful implementation on the Raspberry Pi platform.The proposed cryptographic solution not only ensures the confidentiality of transmitted data but also addresses the resource limitations inherent in edge devices. Focusing on image encryption in surveillance systems, our hybrid lightweight cryptographic algorithm operates seamlessly on the Raspberry Pi, demonstrating its adaptability to low-resource environments.The process begins with the capture of images, followed by their secure storage and processing on the Raspberry Pi. Subsequently, the images are encrypted, and the encrypted files are transmitted over the network. Notably, the security is fortified by incorporating a hash value that accompanies the encrypted file during transmission. At the receiving end, the integrity of the received file is verified by comparing the transmitted hash value with the computed hash value, allowing for the rejection of any tampered or compromised data.This research contributes a holistic solution to the challenges posed by resource constraints in edge computing devices, offering a secure and efficient method for image transmission in surveillance systems. The presented hybrid lightweight cryptographic algorithm not only fortifies the confidentiality of data but also ensures the integrity of transmitted information, making it a valuable addition to the evolving landscape of secure IoT applications.
Comparative Investigation of Classification Algorithms using Parkinson's Disease Acoustic Analysis Dataset to Choose Best Classifier for Best Result
Authors: Puja Gholap, Krupal Pawar, Vasudha Patil
Published: February 2025

Early diagnostic discovery of Parkinson's Disease (PD) is a serious clinical issue. Owing to the early manifestations of speech impairments in the force of PD patients, the acoustic features of speech have potential to be considered as better early diagnosis standards. In this study, which utilizes a dataset that includes acoustic features associated with PD, we analyze the performance of three machine learning classifiers: Random Forest(RF), Support Vector Machine(SVM), and k-Nearest Neighbors(k-NN) classifiers. In one-second audio segments, a feature extraction was carried out based on principles of jitter, shimmer, harmonics-to-noise ratios, and recursive feature elimination (RFE), as an approach to eliminate the unhelpful features without hindering the model prediction. The classifiers were developed in MATLAB and evaluated based on accuracy, precision, recall, and F1-score using a 10-fold cross-validation method to ensure rigorous assessment. The results showed that RF achieved the highest recall and accuracy (93.0% and 92.3%, respectively), highlighting the suitability of RF as a PD diagnostic model. While k-NN had the lowest results, SVM was precise but scored low on recall. Such works highlight the promise of RF and feature selection in the construction of diagnostic tools for PD, addressing the key concerns of non-invasiveness and improved patient outcomes.

Penelitian ini bertujuan menganalisis pertumbuhan total faktor produktivitas (TFP) pada industri minyak sawit mentah (CPO) di Indonesia menggunakan data tingkat perusahaan tahun 2010 sampai 2014, menggunakan metode stochastic frontier analysis (SFA). Pertumbuhan TFP dibagi menjadi tiga komponen perubahan: efisiensi skala (SE), teknologi (TC), dan efisiensi teknis (TE). Hasil penelitian menunjukkan masih adanya inefisiensi pada industri CPO di Indonesia, ditandai dengan peningkatan jumlah perusahaan dengan nilai TE yang rendah setiap tahunnya, TFP secara keseluruhan tumbuh negatif, serta nilai elastititas yang menunjukkan industri CPO mengalami decreasing return to scale. TEC berkontribusi lebih besar terhadap pertumbuhan TFP dibandingkan TC dan SEC, sedangkan input bahan mentah mempunyai dampak yang lebih besar terhadap fluktuasi produksi dibandingkan modal, tenaga kerja, atau energi.

Penelitian ini bertujuan mengetahui gambaran umum kemiskinan beserta faktor-faktor yang diduga memengaruhi kemiskinan dan mengidentifikasi faktor-faktor yang memengaruhi kemiskinan di Indonesia. Metode yang digunakan yaitu analisis regresi spasial data panel. Hasil penelitian menemukan bahwa terdapat efek spasial pada kemiskinan di Indonesia. Indeks Pembangunan TIK (IP-TIK), persentase pengguna telepon seluler, dan indeks pembangunan manusia (IPM) signifikan menurunkan tingkat kemiskinan di Indonesia. Sebaliknya, angka buta huruf dan tingkat pengangguran terbuka signifikan meningkatkan tingkat kemiskinan di Indonesia. Oleh karena itu, selain dari sisi sosial ekonomi juga perlu menjadikan TIK sebagai bagian penting dari strategi pembangunan yang lebih luas untuk mengentaskan kemiskinan di Indonesia.

Nas últimas décadas, os discursos sobre desenvolvimento sustentável, impactos das mudanças climáticas e a necessidade de políticas efetivas para a preservação do meio ambiente têm se tornado cada vez mais recorrentes, tanto no cenário nacional quanto internacional. Dada a relevância dessas questões na atualidade, este artigo objetiva explorar e analisar como a Educação Ambiental (EA) está inserida na formação de professores, considerando os principais marcos legais que regulamentam essa área no Brasil. A pesquisa adota uma abordagem qualitativa, utilizando-se de pesquisa documental e bibliográfica. Como referências centrais, baseamo-nos para discussões curriculares e da formação de professores em Nóvoa (2012), Saviani (2009) e Silva (2016) e na obra de Mendonça e Dias (2019) e Leff (2012) para problematizar as questões ambientais e de sustentabilidade. Como resultados encontrados, a pesquisa revela a importância da EA na formação inicial de professores, destacando sua contribuição para a interdisciplinaridade e a formação cidadã. No entanto, também foram identificadas lacunas significativas em relação à formação continuada e aos saberes produzidos pelos docentes no âmbito da EA, sugerindo áreas promissoras para pesquisas futuras.

A genética é um tema importante ensinado nas escolas, ela investiga como o material hereditário é transmitido de uma geração para outra através dos genes e como ele se expressa. Assim, com o objetivo de ampliar o conhecimento dos estudantes sobre genética humana, aproximá-los do meio acadêmico e incentivá-los o estudo das ciências biológicas, foi realizado um trabalho na Escola de Referência em Ensino Médio (EREM) Ginásio Pernambucano, em 26 de setembro de 2023, pela Liga Acadêmica de Genética Humana. A atividade envolve um workshop sobre "Genética do Sangue", utilizando materiais simples e acessíveis, como pequenas bolas de isopor, palitos de dente pintados em verde e amarelo, além de sucos em pó de uva e laranja para representar antígenos e anticorpos presentes no sangue. Durante o workshop, foram distribuídos panfletos sobre doação de sangue e promovida uma roda de conversa com os alunos. As três dinâmicas  realizadas despertaram grande interesse e curiosidade, levando os estudantes a discutir temas como doação de sangue, tipagem sanguínea, hemofilia e eritroblastose fetal. A interação entre os alunos da EREM Ginásio Pernambucano, os membros da Liga Acadêmica de Genética Humana e os funcionários da escola propôs a eficácia das práticas extensionistas, promovendo o desenvolvimento cognitivo dos estudantes do ensino médio e contribuindo para a aprendizagem de conteúdo das ciências biológicas.

200 chủng Klebsiella pneumoniae phân lập từ bệnh phẩm dịch hô hấp và dịch ổ bụng tại Bệnh viện Bạch Mai năm 2022 - 2023 được làm kháng sinh đồ bằng hệ thống tự động BD Phoenix M50. Tất cả được xác định 5 kiểu gene mã hóa carbapenemase thường gặp (blaNDM, blaOXA-23, blaOXA-48, blaIMP, blaKPC) bằng kỹ thuật PCR. Kết quả cho thấy các chủng K. pneumoniae từ đường hô hấp có mức độ nhạy cảm thấp (16 - 51%), các chủng K. pneumoniae phân lập từ dịch ổ bụng có mức độ nhạy cảm cao hơn (51 - 71%) với các kháng sinh thử nghiệm. 42,5% các chủng K. pneumoniae mang các gene mã hóa cho carbapenemase. Kiểu gene mã hóa carbapenemase phổ biến nhất là blaKPC (21%), blaNDM (15%), không phát hiện chủng nào mang blaIMP. Có 51 trong số 85 chủng mang gene mã hóa carbapenemase phối hợp như blaKPC + blaOXA-48, blaKPC + blaNDM, blaKPC + blaOXA-48 + blaNDM và đều đề kháng cao với hầu hết các kháng sinh. Dữ liệu nghiên cứu cung cấp cơ sở cho các bác sĩ lâm sàng trong việc lựa chọn kháng sinh điều trị theo kinh nghiệm cho các nhiễm trùng do K. pneumoniae khi chưa có kết quả kháng sinh đồ.

Tắc ruột sau mổ là một bệnh lý phức tạp liên quan đến lần mổ bụng trước do tình trạng dính ổ phúc mạc. Phương pháp xử trí tùy thuộc vào mức độ dính, tổn thương ruột và kinh nghiệm của phẫu thuật viên. Bài báo nhằm tổng kết kinh nghiệm phẫu thuật bệnh này tại một trung tâm. Chúng tôi hồi cứu các trường hợp được mổ mở tại Bệnh viện Bạch Mai từ 1/2018 đến 12/2023. Kết quả gồm 42 bệnh nhân. Tuổi trung bình là 54,9 ± 15,7 (24 - 96) tuổi, nam/nữ là 0,9. Tỷ lệ người bệnh sau mổ sản khoa, cắt ruột thừa và cắt ruột non lần lượt là 35,7%, 35,7% và 19%. Người bệnh đã mổ bụng một, hai và ba lần là 71,4%, 26,2% và 2,4%. Tỷ lệ cắt dây chằng + gỡ dính, gỡ dính đơn thuần, cắt đoạn ruột non và tháo xoắn lần lượt là 19,1%, 42,8%, 31% và 7,1%. Tai biến trong mổ hay gặp là rách thanh cơ ruột non (40,5%) và thủng ruột (4,8%). Thời gian trung tiện và nằm viện sau mổ là 3,6 (2 – 6) và 9,7 (5 – 21) ngày. Kết quả cho thấy mổ mở là cách tiếp cận khả thi và hiệu quả để điều trị hầu hết các trường hợp tắc ruột sau mổ. Tuy nhiên, mổ điều trị tắc ruột luôn có nguy cơ tai biến thủng ống tiêu hóa, rách thanh cơ ruột.
