Published: March 2024

Politeness is essential in interaction to avoid conflict between the speaker and the hearer. This article describes politeness by students and lecturers in academic interaction at the Japanese Program in Undiksha. This study is qualitatively approached using pragmatics design. The data were collected using the technique of observation by listening, writing notes, and participating.  The data was then, analyzed using an interactive model from Miles & Huberman. The data were classi?ed according to the face theory of Brown & Levinson i.e. strategy of positive politeness and ?rategy of negative politeness. Data analysis reveals positive politeness strategies and negative politeness strategies students use in academic interaction at the Japanese Program in Undiksha. Both methods contained a constituent such as code-mixing. The reason for using code mixing in speech between lecturer and students is not only from speech situation but most part because of politeness factor. Using code-mixing of the Indonesian language and Japanese, made the speaker comfortable speaking because the code-mixing can make the utterance still in polite mode and formal form.

Pasca-Apokaliptik: Hubungan Alam dan Manusia pada Anime Gin’iro No Kami No Agito Karya Keiichi Sugiyama
Authors: Jelia Ni Made Dwi Marta , Wiriani Ni Made , Oeinada I Gede
Published: March 2024

The title of this research is "Post-Apocalyptic: The Relationship Between Nature and Humanity in the Anime 'Gin'iro No Kami No Agito' by Keiichi Sugiyama." The purpose of this study is to describe the portrayal of post-apocalyptic life, environmental values, and the relationship between nature and humanity in the anime 'Gin'iro No Kami No Agito.' The research methodology in this study is the qualitative descriptive method. For the theoretical framework, the study draws from the field of literary ecocriticism, as formulated by Glotfelty. Based on the research findings and analysis conducted, the relationship between nature and humanity in the anime 'Gin'iro no Kami no Agito' leans toward a more positive orientation in the post-apocalyptic era. In this context, humanity places a strong emphasis on fostering harmony with nature, which is reflected in their behavior that consistently takes into account the well-being of the environment. However, the repercussions of the apocalyptic event also give rise to negative interactions, such as the anxiety experienced by humans due to the pressure exerted by the forest and the actions of Laguna City, which employ force to subdue nature. Consequently, the anime depicts how humans, in general, experience a sense of being burdened by the natural world, leading to anxiety and resistance. This results in an unstable relationship between humanity and nature, ultimately dividing the human population into two groups: Neutral City and Laguna City.

Исследовано 70 индивидов, основное внимание уделено определению ключевых демографических и палеопатологических характеристик группы. Распределение показателей смертности в группе в целом соответствует стандартному для палеопопуляций, как внутри всей группы, так и для мужской и женской ее частей. Для группы характерен ранний возраст смерти, умеренно высокая детская смертность, низкая доля пожилого населения. По результатам палеопатологического исследования можно выделить такие особенности группы как преобладание травм бытового характера, а также сравнительно высокий уровень встречаемости признака cribra orbitalia. Все выявленные особенности могут отражать характер адаптации группы к новым условиям жизни на первых этапах формирования колонии.
Хронологические особенности погребального обряда Аверинского II могильника
Authors: Моряхина Кристина Викторовна
Published: March 2024

Аверинский II могильник расположен на правом берегу р. Камы в 900 м к северо-западу от д. Аверины Афанасьевского района Кировской области. Раскопки на памятнике проводились в 1975–1976 гг. под руководством Р.Д. Голдиной, в 1978 г. – В.А. Кананина, в 1982–1984 г. – Е.М. Черных. Всего изучено 440 погребений. Памятник датирован VI–XI вв. Хронология могильника разработана Р.Д. Голдиной и В.А. Кананиным. Исследователями был описан только инвентарь, характерный для разных веков, но не рассмотрены изменения, происходящие со временем в самом погребальном обряде. В данной статье затронут именно этот аспект. Погребальный обряд населения, оставившего Аверинский II могильник, не претерпевал серьезных изменений на протяжении шести веков. В разное время на памятнике часто делали большие ямы, начиная с VIII в. сооружали внутримогильные конструкции. По материалам могильника заметно, как со временем культ огня играл все более важную роль. Это видно по увеличившемуся количеству погребений с кремацией и с углями в засыпи. Начиная с VII в. в погребения стали класть вооружение и конскую упряжь, с VIII в. – орудия труда. Последнее отражает важное значение хозяйства (земледелия, рыболовства и деревообработки) для населения. Наибольшее количество захоронений пришлось на IX в., при этом погребальный обряд в этом веке на Аверинском II могильнике не соответствует традиционному представлению об урьинском этапе ломоватовской культуры (конец VIII–IX вв.). На могильнике сохранились те традиции, которые были характерны для более раннего времени.
Development of A Structural Equation Model of The Variables Affecting the Organizational Performance of The Mass Rapid Transit Systems of Thailand
Authors: Punthupeng Sutep , Phimolsathien Thepparat
Published: March 2024

Introduction: The development of the Thai transport system in the future must be based on the advancement of three aspects: personnel, technology, and research and development must be promoted for the operation of efficient innovative tools and management as key mechanisms in the transport system’s development. The master plan of the Ministry of Transport under Strategy 5 for the development of the Thai transport system within 20 years (2017-2036) stated about the need for and initiation of technology and innovation, as well as the promotion of research and development for the application of rapid advancements within these aspects so to develop the transport infrastructure and management, which would engender higher efficiency of future transport as well. Technology is required and is suitable for the analysis and evaluation of performance in the view of safety technological innovation for subway station construction.
 
Objective: The main objective was to explore the development, congruence, and the indirect direct, and total effects of the variables affecting the organizational performance of the mass rapid transit systems of Thailand
 
Method: This is quantitative research, collecting data from 385 executives and chiefs of organizations relating to the mass railway transit systems and private manufacturers participating in the project with state enterprise agencies.
 
Result: Relationship between the two variables and among the multiple variables in conjunction with the estimation of the effects of the variables, which were obtained from the regression coefficients (coef.) of each individual relationship path following the hypothesis. The results indicated that all C.R. ( t-test) values were statistically significant ( > 1.96). Thus, every hypothesis was supported. Technology directly affects organizational performance (coef. = 0.143, p < 0.05). Technology directly affects innovation (coef. =  0.370, p < 0.001). Technology directly affects research and development (coef. =  0.786, p < 0.001). Research and development directly affects innovation (coef. =  0.624, p < 0.001). Research and development directly affects organizational performance (coef. =  0.449, p < 0.001). Innovation directly affects organizational performance (coef. =  0.372, p < 0.01).
 
Conclusion: Technology, innovation, and research and development truly affect organizational performance. The industrial sector should be more encouraged to participate in technology learning and to step into the manufacturing chain for the development of Thailand’s rail transport system. This would also save foreign currency, create employment opportunities in the country, and have continual economic effects for the national monetary circulation, which would eventually pave the way to the enhancement as well as development of the people’s abilities in the future.

Results: The AHP analysis results indicate that simultaneous impact criteria are the main criteria for determining priority strategies.
 
Conclusions: Thirteen strategies were formulated based on the SWOT analysis. The medium-term plan's management priority strategies have been determined based on the results of the AHP analysis. These strategies include: (1) Controlling the level of water pollution and household waste, (2) Revitalizing the lake, (3) Developing institutions for integrated lake ecosystem management, and (4) Planning the spatial layout of the lakes and their boundaries.
Look Behind You! Playing with Sexual Surveillance in You Must Be 18 or Older to Enter and how do you Do It?
Authors: Ketterling Jean
Published: March 2024

In this article, I consider two indie videogames, You Must Be 18 or Older to Enter (Seemingly Pointless 2017) and how do you Do It? (Freeman et al. 2014), that share an interest in the affective impact of parental surveillance and discipline on childhood sexual exploration. Using close playing as my method, I argue that the videogames reveal the perils of surveillance and its pleasures. Drawing on assemblage theory, I demonstrate the contingency of videogames’ affective impact on players and the world and the—sometimes contradictory—potentials that surveillance produces as part of a sexual assemblage. Sometimes, using surveillance as a game mechanic amplifies sexual affect and pleasure and can thus be conceptualized as an example of “flirting” with surveillance. At other times, players orient themselves toward the videogames as the archetypical “parent”—finding pleasure in “catching” a videogame about sexual exploration and attempting to discipline it. Finally, drawing on Kathryn Bond Stockton (2004, 2009, 2017) and José Esteban Muñoz (2019), I argue that, by allowing players to relive childhood sexual exploration as adults, You Must Be 18 or Older to Enter and how do you Do It? provide players with the opportunity to become a playful child, to loop back through time and re-explore sexual discovery, and thus shape nuanced critiques of the way surveillance shapes sexual possibilities.
Capital City Cruising: Surveillance, Pleasure, and Discursive Practices of Queer Communities in Ottawa
Authors: Kenyon Miles
Published: March 2024

This study investigates how men who have sex with men (MSM) discern, discuss, and defy issues of surveillance in the context of casual, public sex​​—also known as cruising—and how these exchanges constitute and inform subaltern counter-surveillance measures. Focusing on written exchanges by users of the queer hook-up website Squirt, I analyze how individuals share information about the safety and surveillance of cruising locations in the Greater Ottawa Area. This work concludes that surveillance and cruising is normalized, and that both police and ordinary citizens present safety risks. Because of this, great care is taken to act discreetly and not infringe on the safety of non-cruisers. Finally, environmental factors contribute greatly to both the construction and circumvention of surveillance infrastructure. The data additionally complicate surveillance realism (Dencik and Cable 2017), since cruisers accept the presence of surveillance but not the inevitable impact of it.

This study sought to determine the perception of healthcare workers (HCWs) about pre-hospital airway management and their experiences.
Methods:
This cross-sectional study was conducted among health workers at the emergency department of King Fahad Medical City in the capital of Saudi Arabia, Riyadh City. This study targeted physicians, nurses, paramedics, and respiratory therapists. Data were collected using an online questionnaire. The questionnaire included demographic characteristics, training, and experiences in airway management and a 5-item questionnaire to measure the perception of HCWs about airway management.
Results:
Of the 100 HCWs, 39% were doctors, and 37% were nurses. Approximately 23% had a poor experience with intubation. Traumatic injuries were the major difficulties involving airway management (44%). The overall perception of HCWs about prehospital airway management was good (68%), 31% were moderate, and only 1% were considered poor perception levels. No significant differences were observed between perception scores in relation to the demographic characteristics and experiences of HCWs in airway management (all p>0.05).
Conclusion:
Despite HCWs' good perception of prehospital airway management, some gaps have been identified mainly through intubation skills and experiences. This study provided evidence that perception towards prehospital airway management was not affected by profession, years of experience, regular practice of intubation, and airway management. Regular training should be implemented, with equipment and resources should be available to improve airway management and patient quality of care.

Authors: Hashim Intesar H. , Hussein Bushra J. , Oudah Abdel Karim L.
Published: March 2024

The beam transport system is an essential part of any accelerator.  This research investigates how a charged particle beam extracted from a plasma source behaves as it passes through a virtual beam transport system consisting of a series of C-bending magnets. This is done by analyzing the equations of motion of charged particles through this system. In addition, the study investigates the effect of the free drift space regions between these magnets and studies the behavior of charged particles beam passing through the suggested system for both horizontal and vertical planes using a computer program designed for this purpose. The results indicate many focusing regions along the beam path (beam envelop) for both the horizontal and vertical planes. The presence of free drift regions between the magnets strongly affects the beam envelop for both horizontal and vertical planes.

Published: March 2024

In this work, the concept of the paracompact map has been generalized to other new types of maps, in addition to the fact that the paracompact map has been linked to these new maps.  Accordingly, we will separate these new types of maps into two classes, the first class is called a strong form which implies a paracompact map under certain conditions. While the other class is called a weaker form of a paracompact map, whereas the paracompact map implies them. Finally, the composition operations of paracompact maps are studied.

The analysis of observed data at different time points is prominent to single problems when the scientist studied random sampling data over time restricts the applicability of many traditional statistical methods that require random sampling. The analysis of this data is usually mentioned to the stochastic process, in a special case, if it relates to time, then it is called time series [1].  The aim of our study is to focus on the case of observations that are made at certain times of the year, specifically in the autumn season, in equal periods of time, and we estimate the effect of interference on wheat prices n order to obtain the best predictive model and the best order of this model for the overall effect on the price of wheat for the coming years.
A New Hybrid Algorithm Based on the Firefly Algorithm and Cuckoo Search to Estimate Survival Analysis of Truncated Inverse Gompertz Distribution
Authors: Jabbar Noor Abdul Ameer , Kalaf Dr.Bayda Atiya
Published: March 2024

This paper introduces the Right Truncated Inverse Gompertz Distribution (RTIGD) with two parameters δ and ϑ with some of its properties as; (Survival-Function, Hazard-Function, cumulative distribution function, probability density function, ‎r-th moment, mean, variance, Moment Generating Function, Median, and Mode. In addition, we propose a new hybrid algorithm, namely the firefly Algorithm with Cuckoo Search Algorithm (FA_CSA) to estimate the parameters based on the survival functions of RTIGD. Simulation is utilized to compare the proposed algorithm with traditional methods, for example, the Maximum Likelihood Estimator and moment method and the standard algorithms Firefly Algorithm and Cuckoo Search. In most cases, the results demonstrate that the proposed algorithm (FA_CSA) provides an accurate estimation for the survival function since it has less mean squared error than the other estimation methods.
Evolutionary-based Gene Ontology for Complex Detection in Protein-Protein Interaction Networks
Authors: Kadhim Mustafa Abdulhussein , Al-Dabbagh Rawaa Dawoud
Published: March 2024

Complex detection in protein-protein interaction (PPI) networks is one of the major issues facing scientific study in biological networks. In PPINs, proteins are distributed differently as groups (complexes). These groups can be identified as having a great internal density in the number of edges inside the groups while having the least possible number of edges between these groups. The most common methods for finding such complexes are evolutionary algorithms (EAs), which have been used widely in literature for this objective. Despite the reliability of these complicated detection models, they are mostly based on topological (graph) qualities, and the biological implications of the PPI networks have been rarely explored. In this research, EA with mutation-based gene ontology is developed, particularly in the mutation part where the functional annotation of the protein has been considered using gene ontology structure. The experimental results prove the reliability of the proposed method using standard validation measures. It also outperforms the state-of-the-art method in terms of the prediction ability and quality of the complexes found.

Authors: Essa Khaled S. M. , El Saied Sawsan I. M. , Wheida A. A. , El-Nazer Mostafa
Published: March 2024

This study investigates instantaneous and continuous sources as point, line, and area sources. Gaussian concentration in the case of the puff model with an instantaneous point source inhomogeneous longitudinal diffusion is investigated. The concentration is calculated using different dispersion parameters to get the proposed normalized concentration of the puff model at ground level around the centerline, which is compared with observed data by the Copenhagen experiment and previous work [1].
Also, the continuous point source is used to get the Gaussian plume model in three dimensions using dispersion parameters to compare with the observed concentration data measured by the Egyptian Atomic Energy Authority for Iodine-135 (I135) in an unstable condition.
The Roles of Potassium Channels and Nitric oxide in the Modulation of Apelin induced-relaxation in Isolated Diabetic Rat Aorta
Authors: Othman Hawzheen K. , Mahmud Almas MR. , Maulood Ismail M.
Published: March 2024

Diabetes is associated with endothelial dysfunction, which impairs blood vesselscapacity to maintain vascular tone. Apelin is an adipocyte-produced relaxing factor that has endothelium-dependent and nitric oxide (NO)-mediated vasorelaxant effects. The current study investigated how streptozotocin (STZ)-induced type one diabetes modulates the mechanisms involved in aortic vascular response to apelin, focusing on the role of potassium channels and endothelial derived relaxing factors (EDRF). In this study, precontracted rat thoracic aortic segments were pre-incubated with the NO inhibitor, cyclooxygenase (COX) inhibitor and potassium channels blockers including: non-selective calcium-activated potassium channel, big conductance calcium-activated potassium channels (BKca), intermediate conductance calcium activated potassium channels (IKca), delayed inward rectifier potassium channels (Kir), adenosine triphosphates-sensitive potassium channels (KATP) and voltage sensitive potassium channels (Kv) blockers, then cumulative concentrations of apelin were applied to each group in both non-diabetic and diabetic conditions. The statistical analysis between diabetic and non-diabetic groups revealed that endothelial impairment induced by diabetes in rat thoracic aorta remarkably attenuated the vascular responses to apelin. An important new finding in this study was that almost all potassium channels blockers noticeably P<0.001 increased apelin efficacy with relatively no changes in the peptide potency. However, in diabetic aortic segments, the non-selective Kca, BKca blockers, NO inhibitor and COX inhibitor reversed vascular responses to apelin, but Kir, KATP and Kv blockers significantly reduced vascular responses to apelin in comparison to control rats. It is worth noting that diabetes did not only alter the peptide potency in these experimental groups but also significantly increased the maximum responses when Kca and BKca blockers preincubated. In conclusion, our findings shed light on the mechanisms behind diabetes-induced aortic artery hypo-reactivity to apelin which involve the inhibition of endothelial NO synthase activities and decreased contribution of Kca, BKca, IKca, Kv, Kir and KATP channels.

Penelitian ini mempunyai tujuan untuk mengetahui integrasi bisnis pelayaran tradisional dalam logistik nasional dan mengetahui peluang pelayaran tradisional Pelabuhan Tanjung Emas Semarang dalam logistik nasional. Penentuan prioritas pengelolaan dilakukan dengan menggunakan analisis AHP yang didukung dengan observasi, wawancara, angket, dan studi dokumen untuk mengungkap faktor-faktor internal dan ekternal pada bisnis pelayaran tradisional di Pelabuhan Tanjung Emas Semarang dalam logistik nasional. Prioritas ditentukan oleh indeks yang diperoleh dari analisis. Berdasarkan data yang diperoleh, analisis menghasilkan tingkat inkonsistensi sebesar 0,02% yang mengindikasikan tingginya konsistensi pendapat para ahli tentang prioritas pengelolaan, policy support, competitiveness, market insurance, human resource capacity, business incentives, infrastructures facilities, dan management. Berdasarkan prioritas pengembangan pelayaran tradisional, hanya tiga dari tujuh aspek yang memperoleh perhatian tinggi. Aspek Policy support, human resource capacity, dan market tersebut memiliki indeks yang jauh lebih tinggi dengan dukungan program tol laut. Hasil analisis AHP sangat menekankan perlunya dukungan kebijakan dalam integrasi usaha pelayaran tradisional ke tol laut. Hasil analisis SWOT menunjukkan tujuh prioritas pengembangan pelayaran tradisional dengan bisnis pelayaran tradisional membutuhkan dukungan.

Objetivo: Analisar as características do vírus Monkeypox (MPX) e da varíola dos macacos. Revisão bibliográfica: A varíola dos macacos é uma infecção viral zoonótica causada pelo vírus MPX que resulta em uma clinica semelhante à da varíola e que recentemente teve um surto mundial. Sua transmissão pode ocorrer de animais para humanos e entre humanos por contato com secreções respiratórias de indivíduos infectados, lesões de pele ou órgãos genitais, contato face a face prolongado, transmissão sexual e placentária. O processo de infecção por MPX é dividido em duas fases: a fase prodrômica com febre, fadiga, cefaléia intensa, linfadenopatia, dores musculares e a fase de erupção cutânea. Considerações finais: A varíola dos macacos surge em um momento fragilizado pós pandemia de coronavírus, e apesar, de sua menor carga viral e baixa letalidade, é fundamental o seu controle, principalmente, através da prevenção de contato. O tratamento da doença é feito através de medidas de suporte e em casos graves ou com progressão para gravidade podem ser utilizados os anti-vírus da varíola como o tecovirimat, cidofovir ou brincidofovir. A vacinação deve com vacinas anti varíola deve ser avaliada caso a caso.

Objetivo: Revisar na literatura a fisiopatologia, o diagnóstico e os tratamentos atuais para endometriose, assim como o impacto da doença no cotidiano das mulheres acometidas. Revisão bibliográfica: A endometriose, caracterizada por crescimento celular progressivo e dependência estrogênica, afeta cerca de 10-15% das mulheres em idade reprodutiva, com uma prevalência global estimada em 176 milhões de casos, é caracterizada por crescimento celular progressivo e dependência estrogênica. O diagnóstico evoluiu para métodos não cirúrgicos, buscando acelerar o tratamento, enquanto a dor crônica, principal sintoma, impacta no absenteísmo ao trabalho e no impacto econômico, manifestando-se de forma cíclica ou não cíclica. Além de estar associada à infertilidade (20-68% das pacientes inférteis), a complexidade da endometriose afeta diversos sistemas e órgãos, demandando uma abordagem multidisciplinar para controle sintomático. Considerações finais: A endometriose, uma condição complexa comum, pode causar angústia significativa, resultando em dores pélvicas crônicas, infertilidade ou afetando órgãos específicos. Essa doença carece de uma causa estabelecida e de um tratamento curativo, evidenciando a necessidade de novas pesquisas para compreender sua patogênese, desenvolver técnicas diagnósticas não invasivas definitivas e orientar tratamentos sem hormônios, especialmente para mulheres que desejam engravidar.
Management of cerebrospinal fluid rhinorrhea as a rare complication of antiphospholipid syndrome
Authors: Xian Elissa , Hardman Joel , Parker Geoffrey , Nirmalananda Arjuna
Published: March 2024

Background:

Antiphospholipid syndrome is a complex autoimmune condition associated with the formation of recurrent thrombosis in any vascular bed throughout the body. Jugular vein thrombosis is very rare with only a 0.9% occurrence and is not typically associated with cerebrospinal rhinorrhea as a result of raised intracranial pressure.

Case Description:

A 54-year-old patient presented with a 9-month history of cerebrospinal fluid (CSF) rhinorrhea and headache on a background of antiphospholipid syndrome. Investigations showed a superior vena cava (SVC) and right internal jugular vein (IJV) obstruction with moderately elevated intracranial venous pressures. Her magnetic resonance imaging (MRI) brain was consistent with a CSF leak. The patient underwent successful endovascular stenting of her obstructed SVC and right IJV followed by surgical repair of a herniating meningocele in the posterior left ethmoid air cells.

Conclusion:

CSF rhinorrhea is uncommon and never previously reported associated with SVC thrombosis induced by antiphospholipid syndrome. A combination of endovascular techniques and surgical repair is recommended for this challenging presentation.
Adjuvant proton beam therapy in patients with grade 2 meningiomas

Published: March 2024

Background:

The World Health Organization (WHO) grade 2 meningiomas behave aggressively with a high proclivity toward recurrence despite maximal surgical resection. Our institution, a pioneer of proton therapy, uses exclusively proton beam radiation, and thus, we present a retrospective cohort analysis of patients with WHO grade 2 meningiomas treated with adjuvant proton beam therapy (PBT) at our institution between 2007 and 2019. The effects of adjuvant PBT were evaluated.

Methods:

Data collected include diagnosis, gender, histological subtype, WHO grade, the extent of surgical resection, adjuvant PBT radiation, details of the PBT radiation, recurrence, any additional PBT radiation, systemic medical therapy, and disease-specific survival.

Results:

Among the WHO grade 2 meningiomas (n = 50) recommended PBT, 80% and 78% of patients with gross-total resection (GTR) and subtotal resection (STR), respectively, followed through with PBT. The median radiation dose of PBT was 59.5 Gy and 59.92 Gy for patients with GTR and STR, respectively, with a median of 33 fractions delivered in 1.8 Gy doses for both groups. Combined 3-year progression-free survival (PFS) was 96%, and 5-year PFS was 92%. Combined overall survival was 95% at five years. Minimal radiation side effects were reported with no grade 3 or higher toxicities.

Conclusion:

Our results suggest that adjuvant PBT is well tolerated with minimal radiation toxicity. Alternative to photon radiation, PBT may be considered at least as safe and effective for adjuvant treatment of WHO grade 2 meningiomas when it is available.

Published: March 2024

Background:

Chronic subdural hematoma (cSDH) is a common sequela of traumatic brain injury. Middle meningeal artery embolization (MMAE) has shown promising results as an emerging minimally invasive alternative treatment. The purpose of this study is to examine the safety and efficacy of MMAE performed in patients with cSDH, acute-on-chronic, and subacute SDH with a traumatic etiology.

Methods:

This retrospective study included cases performed at a Level II Trauma Center between January 2019 and December 2020 for MMAE of cSDHs. Data collected included patient demographic characteristics and comorbidities, SDH characteristics, complications, and efficacy outcomes. The lesion measurements were collected before the procedure, 4–6 weeks and 3–6 months post-procedure.

Results:

In our patient population, 78% (39) either had lesions improve or completely resolved. The sample included 50 patients with a mean age of 74 years old. Statistically significant reductions in lesion size were found from pre- to post-procedure in the left lesions, right lesions, and midline shifts. The left lesions decreased from 13.88 ± 5.70 mm to 3.19 ± 4.89 mm at 3–6 months with P < 0.001. The right lesions decreased from 13.74 ± 5.28 mm to 4.93 ± 7.46 mm at 3–6 months with P = 0.02. Midline shifts decreased from 3.78 ± 3.98 mm to 0.48 ± 1.31 mm at 3–6 months with P = 0.02. No complications were experienced for bleeding, hematoma, worsening SDH, pseudoaneurysm, or stroke.

Conclusion:

Our pilot study from a single center utilizing MMAE demonstrates that MMAE is successful without increasing treatment-related complications not only for cSDH but also in acute-on-cSDH and SDH with a subacute component.
