Authors: Heni Dwi Iryanti  , Wawo Paulus , Purnomo Cahya
Published: January 2025

Waktu tunggu kapal merupakan salah satu indikator penting dalam efisiensi operasional pelabuhan, dimana antrian yang panjang dapat menyebabkan penundaan yang signifikan, peningkatan biaya operasional, dan gangguan dalam rantai pasokan logistik. Sebagai pintu gerbang penting bagi wilayah Nusa Tenggara Timur, Pelabuhan Kelas III Labuan Bajo mengalami berbagai tantangan operasional yang mempengaruhi efisiensi logistik dan distribusi barang. Meskipun pelabuhan ini memiliki potensi besar sebagai pusat distribusi, permasalahan seperti lamanya waktu tunggu kapal masih menjadi kendala utama. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang mempengaruhi waktu tunggu kapal General Cargo di Pelabuhan Kelas III Labuan Bajo dengan pendekatan kualitatif dan kuantitatif. Data yang dianalisis meliputi waktu bongkar muat (loading dan unloading time), rasio pemakaian dermaga (berth occupancy ratio (BOR)) dan waktu tidak operasional (non-operating time (NOT)), yang dikombinasikan dengan wawancara dan observasi. Hasil penelitian menunjukkan bahwa keterbatasan fasilitas pelabuhan dan ketidak efisienan operasional merupakan faktor utama yang mempengaruhi waktu tunggu. Perbandingan dengan standar pelayanan pelabuhan dari Direktoran Jenderal Perhubungan Laut Kementerian Perhubungan mengindikasikan bahwa tingkat pelayanan saat ini belum memenuhi standar. Penelitian ini menyarankan perbaikan pada manajemen operasional dan penambahan fasilitas pelabuhan untuk mengurangi waktu tunggu kapal. Penelitian ini berkontribusi pada pemahaman yang lebih mendalam tentang tantangan operasional yang dihadapi oleh pelabuhan dan memberikan wawasan bagi pengembangan strategi untuk mengurangi waktu tunggu kapal yang pada akhirnya dapat meningkatkan efisiensi operasional dan daya saing pelabuhan.

Authors: Lestari Denisa Putri , Nugroho Muhammad Aprianto Budie , Solihat Dadang , Fadhly Fahrus Zaman
Published: January 2025

This study examines the translation equivalence and techniques used in translating idiomatic expressions in the subtitling and dubbing of the movie Raya and the Last Dragon. Using a qualitative case study approach, 72 idiomatic expressions were analyzed based on Nida Taber’s theory of translation equivalence and Molina and Albir’s translation techniques. Results showed that 51% of subtitling and 52% of dubbing translations were equivalently translated into idiomatic expressions, while the remaining were rendered as non-idiomatic expressions due to the lack of equivalent idioms in the target language. Single translation techniques dominated, accounting for 98% in subtitling and 99% in dubbing, with established equivalence being the most frequently used technique. This highlights the translator's ability to maintain idiomatic meaning and cultural relevance. The study recommends exploring idiomatic translation strategies in diverse audiovisual media and cultural contexts to further enhance the understanding of effective translation techniques.Keywords: Translation techniques; idiomatic expressions; subtitling; dubbing; equivalence; established equivalence; audiovisual translation.

BILABIAL FRICATIVE VOICELESS - VOICED SOUND BARRIER FOR SUNDANESSE SPEAKERS: A PEDAGOGICAL APPROACH
Authors: Yusuf Teddy , Syhabbuddin Syhabbuddin
Published: January 2025

There are different educational institutions covering English as a foreign language in the country. In big cities, English is even taught in kindergarten, either because learning English is prestigious or because of school competition. Learning English was not a serious difficulty for some students of foreign languages, like the European states. But in Asia, that's not always the case — especially for those who speak a Polynesian language, and especially for the Sundanese. This is especially true for bilabial consonant sounds, which Sundanese speakers have difficulties pronouncing. These pronunciation variations are perfectly normal, because every language has its own sound inventory.Without a doubt, Sundanese and English differ markedly in their segmental phonology. Using two different languages in the same article for pedagogic purposes teaching English to a Sundanese speaker, this article is going to state the differences and similarities between the two. The contrastive analysis will highlight the differences and similarities between the two languages which will help language teachers and learners to overcome problems facing them in pronouncing English sounds.This study will investigate the differences and similarities between the consonant pronunciations in the two languages, with an emphasis on bilabials. The methodology used in this research is descriptive-qualitative. Using the approach of contrastive analysis, different similarities and differences of influence with the two languages are detailed, especially in bilabial consonant pronunciation. Due to language-specific differences between bilabial sounds, it is hoped that the findings would be a useful reference for language teachers and learners to prepare for targeted training or therapy. And the researcher hopes this study may assist language teachers for other languages, as well as speakers of Mandarin Chinese or similar languages, to overcome the production of bilabial sounds in English.Keywords: Contrastive Analysis; Inventory, Consonant; Sound Segment.

Published: January 2025

One of the few countries with high humidity levels, it can cause poor air quality and an increase in diseases such as dengue fever. Dengue fever is a disease caused by the Aedes aegypti mosquito. Due to the large number of cases of dengue fever, various types of drugs have emerged to treat this condition. Predator, genetics, pathogen and parasite control, as well as physical, biological and chemical control are several ways to control larvae. Efforts to control mosquitoes can be made by using mosquito repellent repellents by using plants that come from nature which contain essential oils as environmentally friendly repellents. One of the plants that contain essential oils is soursop leaves and ylang-ylang flowers. The aim of this research was to determine the effectiveness of soursop leaves and ylang-ylang flowers as larvicides to eradicate mosquito larvae. This research is experimental in nature with the samples used, namely Culex type mosquito larvae. This research was conducted at the Biology Laboratory, Faculty of Teacher Training and Education, Universitas Muhammadiyah Surakarta. The samples for this study were 28 containers with an initial number of larvae of 25 individuals. The results showed that there were several mosquito larvae that experienced death with the lowest mortality in F1D1 with an average of 20 deaths and the highest mortality in F3D3 with an average of 23.67 deaths. Mosquito larvae experienced death with the highest time at 9 hours of observation and the time of death decreased at 12 hours of observation. The use of larvicidal extracts from soursop leaves and ylang ylang flowers is more effective in reducing the number of mosquito larvae with F3 having the highest average number of deaths with a dose of 2.5 g of soursop leaves: 7.5 ylang ylang flowers within 9 hours.

Military service is a special type of activity, in which the stress effect on a person plays a high role. The article is devoted to the study of the influence of cognitive abilities on neuropsychic stability of cadets, as one of the most controversial issues in the medical and psychological support of military personnel. The subject of the study is the influence of cognitive abilities on the neuropsychic stability of cadets. The object of the study is: 1,822 cadets of the Naval Polytechnic Institute aged 18 to 26 years with different levels of neuropsychiatric stability. The sample was divided into three parts according to the level of neuropsychiatric stability. Special attention is paid to statistical data processing as an important element of the scientific method of cognition of the world. The article provides examples of calculating a model for predicting the level of neuropsychiatric stability of the cadets. A comparative study of the cognitive abilities of cadets with different levels of neuropsychiatric stability was conducted. Mathematical modeling was carried out using discriminant analysis. Predictors of a cadet's neuropsychic stability are a combination of indicators of their cognitive development: the ability to establish logical relationships between concepts based on analysis and synthesis operations, the level of development of verbal and logical thinking; tempo characteristics of mental activity, the level of development of operational thinking and operational memory, as well as attention characteristics; the ability to transform visual images in space, the level of development of spatial-figurative thinking. It is shown that the level of communication abilities increases from low to high neuropsychiatric stability. At the same time, the differences between the indicators of cadets with high neuropsychological stability differ significantly compared with cadets with medium and low, the differences between groups with low and medium stability are determined at the trend level. A model for predicting the level of neuropsychic stability was obtained: Wilkes Lambda: 0.95595 approx. F (6.3634)=13.799 p

Published: January 2025

The need to isolate people during the pandemic has put the education system in a situation of transformation of ways of carrying out educational and cognitive activities in conditions of indirect interaction. The transfer of the educational process from the real to the digital environment, including online, without taking into account the specifics of educational and cognitive activity in it, has shown its low effectiveness. Today, digitalization is a priority in the development of education. Ensuring the quality of education in the digital environment requires a fundamentally new approach to the content, motivation, and teaching methods based on scientifically based data on the specifics of the pedagogical process in the digital educational environment. This article presents the results of diagnostics of motivation of educational and cognitive activity of students of various age groups in the digital educational environment according to programs of higher and additional professional education.  Within the framework of the study, various methods of motivation diagnostics were used: N.V. Elfimova's methodology for diagnosing educational motivation (adapted in accordance with the age groups of students and the type of training), T.O. Gordeeva's methodology for diagnosing internal and external educational motivation, A.A. Rean's methodology for diagnosing motivation for achieving success and avoiding failures. As a result of the study of the motivation of educational and cognitive activity of students in the digital educational environment according to the programs of higher and additional professional education, the concept of the digital educational environment is clarified, its main characteristics (cross-border, hypertext, individualization, multi-instrumentality, mediated interaction) are highlighted, the concept of motivation of educational activity is clarified, a number of approaches and constructs of educational motivation are analyzed and generalized, presented the results of the diagnosis of the motivation of educational activities of students of various age groups, the experience of implementing the educational process in the digital environment according to programs of higher and additional professional education is summarized. The results obtained in the course of the study made it possible to determine the directions for improving the pedagogical process in the digital educational environment for the vocational education system, taking into account the identified specifics of motivation of educational and cognitive activity of students of various age groups.

The subject of the research in the peculiarities of psychological well-being and ideas about their own lives among Russian and Kalmyk students. The aim of the research is to study the peculiarities of psychological well-being and ideas about their own lives among Russian and Kalmyk students. The aim of the research is to study the peculiarities of psychological well-being perception among Russian and Kalmyk students; to identify the features of ideas about life in groups of Russian and Kalmyk students; to compare the features of the relationship between indicators of psychological well-being and ideas about life in groups of Russian and Kalmyk students. The sample consisted of two groups of students aged 18-23 years, with a total of 80 respondents. Research methods – the questionnaire "Scale of psychological well-being" (author K. Riff, adaptation by T.D. Shevelenkova and T.P. Fesenko) and the projective drawing technique "My life" (authors: S.A. Bezgodova, A.V. Miklyaeva, S.M. Yatsyshin.). The topic is presented by a relatively small number of studies, as well as due to the relevance of the analysis of the characteristics of the psychological well-being of representatives of different national groups and the lack of research on this topic. No significant differences in indicators of psychological well-being, including the overall level of psychological well-being, were found in the groups of Russian and Kalmyk students. There are no significant differences in the peculiarities of the students' ideas of the selected groups about their own lives, in particular in assessing the general characteristics of life, the emotional background of life, the meaningfulness of life and the "boundaries" with the world and society. Data were obtained on the specifics of the relationships between indicators of psychological well-being and parameters of ideas about one's own life. The conducted pilot study opens up further opportunities to study the topic of the relationship between psychological well-being and ideas about a person's own life, taking into account both the actual qualitative features of the relationships and the influence of various internal and environmental factors on these features.
Subjective experience of loneliness as a predictor of substance use in adolescents
Authors: Komissarova Olga Andreevna , Milovanova Olga Andreevna
Published: January 2025

The subject of this article is the relationship between the subjective experience of loneliness in older and younger adolescents, as well as the ways of forming self-destructive addictive behavior through the use of psychoactive substances (surfactants). The subjective experience of loneliness is a relatively new psychological phenomenon that reflects the subjective experiences of a person in a situation of loneliness. The problem of loneliness has worsened due to the pandemic, the stress of self-isolation has caused an upsurge in addictive behaviors, including compulsive shopping, overeating, alcohol and drug abuse, as well as gambling. Most often, addictions were manifested in people without support from family and friends.Traditionally, in Russian psychological practice, loneliness is considered as a negative phenomenon, but in this study we understand it as a predicative factor (predictor) of the development of dependence on surfactants in adolescence.   The methods used in this study are: the questionnaire method, the method of individual conversation, the method of prevention. Research methods:Questionnaire of loneliness experience by E.A. Manakova; Questionnaire DOPO-3k (Differential questionnaire of loneliness experience) by E.N. Osina, D.A. Leontieva; Methodology "Scale of subjective loneliness experience (SPO)" by S.V. Dukhnovsky; Author's questionnaire "Use of psychoactive substances". The scientific novelty of this study is to study the hypertrophied experience of loneliness as a predictor of the formation of auto-destructive addictive behavior against the background of desirable social integration due to the use of socially acceptable surfactants (nicotine, alcohol). The purpose of the study is to study the subjective experience of loneliness in adolescents as a predictor of auto-destructive addictive behavior. As a result of the conducted research, the main characteristics of the subjective experience of loneliness by adolescents of younger and older age groups and the specifics of the formation of addictive behavior in the aspect of the use of surfactants were revealed.After analyzing various scientific papers and studies, it can be concluded that this problem has not yet been fully studied. The analysis of various scientific sources made it possible to understand that the feeling of loneliness in an acute form first appears precisely in adolescence, when there is a search for one's own identity and connections with the outside world.

Authors: Valdes Odriozola Maria Sant'yagovna
Published: January 2025

The object of the study is sightseeing activities as an aspect of local history work. The subject of the research is cognitive approaches as a method of developing new sightseeing destinations. The purpose of the study is to reveal the creative potential of cognitive approaches in the development of excursion projects. The author, based on the works of academician Dmitry Likhachev devoted to local history, concludes that it is cognitive approaches aimed at studying the phenomenon of everyday life through understanding the interaction of mind and culture that most meet the needs of modern society in matters of cultural immunity formation. The author suggests such a direction as creative regional studies, where creation means higher a form of creativity that aims to transform the surrounding reality for the better. The research methodology includes the combined use of various research methods, which, according to the author, are complementary. This is a Micro-urbanism, which is a set of methods for studying urban space precisely by its "details", methods of visual analysis and thesaurus analysis. The main conclusion from the conducted research is that at the present stage, taking into account the geopolitical situation, there is again a need to develop new areas of local lore that include sightseeing activities, in which cognitive methods can play one of the leading roles. The author's main contribution to the study is to substantiate the relevance of using cognitive methods in the development of new local history work’s directions, to develop a methodology, to reveal the essence and specifics of such a direction as creative regional study, as well as to reveal the creative potential of cognitive approaches. The novelty of the study lies in the fact that local history work has not been previously considered in these aspects.
Virtuality in the understanding of Gilles Deleuze and Henri Bergson and its role for modern philosophy of information science
Authors: Sayapin Vladislav Olegovich
Published: January 2025

The French philosopher Gilles Deleuze (1925–1995) wrote many original works, but one short article, “The Actual and the Virtual,” is, in our opinion, one of the most important. Deleuze’s virtual appears in almost every work, and its influence can be felt everywhere from the idea of singularity to the concepts of differentiation and individuation. That is why the virtual, for Deleuze, is the real, which forms the basis of his philosophical strategy, and where this virtual is opposed not to the real, but to the actual. In other words, Deleuze’s virtual objects are created in perception as memory objects that constitute the object of perception (the actual object). Moreover, according to Deleuze, the unconscious character of his virtual images is probably the greatest obstacle in adapting his theory to the problem of computer-generated virtual worlds. Using the comparative method, virtuality is studied in Deleuze's discussion with Henri Bergson (1859-1941), which is revealed precisely as a process of creative actualization. Unlike the actualization of the possible, which is equivalent to a sudden entry into reality, the actualization of the virtual in Deleuze's sense always occurs through difference, divergence or differentiation. Moreover, for Deleuze, the virtual has the reality of a task that must be accomplished or a problem that must be solved. Therefore, in this article, the author, for the first time, tries to answer the question of whether Deleuze's idea of virtuality can be applied in the philosophy of information science, including for the study of computer virtual worlds. In this case, the main result of the study is the substantiation of the fact that virtuality, both in Deleuze and in Bergson, is an epistemological and not an ontological concept.

Published: January 2025

Objetivo: Analisar as características da Bronquiolite Viral Aguda (BVA) e da Bronquiolite Obliterante (BO). Revisão bibliográfica: A BVA é causada principalmente pelo vírus sincicial respiratório, possui padrão sazonal de incidência, o qual sofreu influência da pandemia da Covid-19. Pode ser causada por coinfecções virais, o que parece determinar um período maior de internação e a identificação de casos graves tem sido facilitada com o uso da ultrassonografia à beira leito. O tratamento é de suporte. A BO é uma doença pulmonar crônica que afeta a qualidade de vida do paciente, sua patogênese não é totalmente conhecida, o que dificulta a elaboração de uma terapia eficaz. Pode dificultar o êxito de transplantes pulmonares e impõe ao doente e seus cuidadores a adaptação da rotina, de forma a garantir o suporte necessário frente a essa condição irreversível. Considerações finais: É preciso estimular mais estudos voltados para essas doenças. Ademais, é imprescindível que profissionais da saúde tenham um bom entendimento acerca delas, de modo que consigam auxiliar no manejo da criança e seus responsáveis, levando em conta suas particularidades.

Published: January 2025

Objectives:

The objective of this study was to evaluate the relationship between the aortomesenteric angle at end-inspiration and end-expiration and its variation rate with several anthropometric parameters.

Material and Methods:

Sagittal reconstructed computed tomography (CT) images of 59 patients who underwent contrast-enhanced CT at end-inspiration and end-expiration between 2015 and 2020 were reviewed. All these patients underwent dynamic contrast CT during both inspiration and expiration for adrenal venous sampling purposes. Two experienced radiologists measured the aortomesenteric angle during both end-inspiration and end-expiration, and its variation rate. Pearson’s or Spearman’s correlation analysis was used to assess correlations between the angle or variation rate and height, weight, body mass index (BMI), visceral fat, subcutaneous fat, and diaphragm motion.

Results:

The aortomesenteric angle was significantly larger at end-expiration (88.65 ± 25.15, 95% confidence interval [CI] 82.09–95.20) compared to end-inspiration (62.22 ± 21.90, 95% CI 56.51–67.93, P < 0.001). The aortomesenteric angles at both end-inspiration and end-expiration correlated significantly with weight, BMI, visceral fat, and subcutaneous fat. The strongest correlation was between aortomesenteric angle and visceral fat at both end-inspiration (r = 0.523, P < 0.001) and end-expiration (r = 0.546, P < 0.001). The variation rate correlated only with diaphragm motion (r = 0.550, P < 0.001).

Conclusion:

The aortomesenteric angle at end-expiration was significantly larger than at end-inspiration, with the strongest correlation found between the angle and visceral fat.
A Pilot Study on the Association between Smoking Behavior of Older Patients with Hypertension and Environmental Factors of Their Residential Area
Authors:   Korea Gerontol Res Soc, Kim Ji Young
Published: January 2025

Smoking cessation should be essential for health management of patients with high blood pressure, but some patients continue to smoke. Although previous studies on smoking cessation in the patients have mainly focused on personal factors, this study focused on environmental factors of the residential area as a preliminary study. For this purpose, the analysis data used in this study were data for 32,119 hypertensive patients aged 55 years or older from the 2019 Community Health Survey data of the Korea Disease Control and Prevention Agency. The data consisted of the respondent’s gender, age, smoking behavior, and five environmental factors of the residential area (safety level, natural environment, living environment, public transportation, and medical service conditions) as dependent measures. Data analysis results revealed that the smoking behavior of the patients was somewhat related to environmental factors in their residential area. In particular, the overall safety level of the residential area and satisfaction with public transportation conditions were revealed to be factors explaining the behavior of the patients. However, the discussion pointed out some methodological problems of the survey tool and raised the need to examine more precisely the association between the community environment and the smoking behavior. This study is significant in that it examined the association between smoking problems in the older patients with hypertension and environmental factors of their residential area.
The Relationship between Childhood Trauma and Depressive Symptoms in Old Age: The Mediating Effects of Experiential Avoidance and Loneliness
Authors:   Korea Gerontol Res Soc, Jeong Yusoo
Published: January 2025

Childhood trauma can have a variety of negative psychological effects throughout the lifespan. The most notable effects include experiential avoidance, increased loneliness, and the onset or intensification of depressive symptoms in later life. This study aimed to verify whether the trauma directly influences depressive symptoms in old age, and whether experiential avoidance and loneliness resulting from the trauma lead to the depressive symptoms. The study participants consisted of 200 men and women aged 65 and older who experienced attachment trauma from their caregivers during childhood. The research data were collected through an online questionnaire of scales measuring childhood trauma, depression, experiential avoidance, and loneliness. The mediating effects of experiential avoidance and loneliness in the relationship between childhood trauma and late-life depressive symptoms were analyzed using Hayes’ Process Macro. The main finding was that childhood trauma did not directly affect on depressive symptoms in late life. However, the trauma had an indirect effect on the symptoms through experiential avoidance as a mediating variable. Furthermore, it was confirmed that experiential avoidance resulting from the trauma intensified feelings of loneliness, which subsequently influenced the symptoms. The findings suggest guidelines for preventing the long-term aftereffects of the trauma that can have negative effects in later life. In other words, preventing depression in older adults with the trauma would be an intervention for the problems of experiential avoidance and loneliness. To address this, specific intervention strategies such as improving communication skills and strengthening social support systems were emphasized.
A Perspective on Association between Cholesterol Levels and Mortality in Old Age
Authors:   Korea Gerontol Res Soc, Oh Bong-Seok
Published: January 2025

One of the physiological indicators explaining mortality risk in older adults is cholesterol level. Generally, it is considered beneficial for health to maintain lower levels of total cholesterol (TC) or low-density lipoprotein cholesterol (LDL-C) as well as higher levels of high-density lipoprotein cholesterol (HDL-C). However, since the 1990s, studies have indicated that this perspective may not apply to all age groups. In other words, in older adults, especially in advanced old age, low levels of TC and LDL-C could signal decreased liver cholesterol synthesis, unknown comorbidities, rapid functional decline, and/or worsened health. Therefore, this study raises the question of whether interventions to lower cholesterol levels are appropriate for older adults and anticipates guidelines for older populations on the relationship between blood lipid levels and mortality.
Adverse Drug Reactions in Older Adults and Preventive Measures
Authors:   Korea Gerontol Res Soc, Kim Jung Sun , Heo Mihyun

A significant portion of the older population, which has increased due to the extension of life expectancy, takes various medications to treat diseases. As the number of drugs taken increases, the risk of adverse drug reactions increases, which are mostly caused by interactions between drugs. In addition, older people are more vulnerable to adverse drug reactions compared to younger people, due to various physiological changes due to aging and multiple co-morbidities. Adverse drug reactions that occur in geriatric patients can result in unexpected emergency room visits, prolong hospitalization, and in extreme cases, lead to death. In addition, individual’s health-related quality of life decreases and medical costs increase, which also increases the social cost burden. However, most adverse drug reactions can be predicted or prevented. Accordingly, the first half of this study looked at the characteristics of adverse drug reactions in the older adults, and the second half discussed preventive measures such as risk management of medications, sharing of prescription information, and role of community pharmacists and consumers.
The impact of the number of aneurysms on the course of the acute period of subarachnoid hemorrhage in patients with multiple intracranial aneurysms

Objective to determine the effect of the number of multiple intracranial aneurysms (MIA) on the course of the acute period of subarachnoid hemorrhage (SAH).
Materials and methods: A cross-sectional retrospective study was conducted involving 92 patients in the acute phase of SAH due to the rupture of MIA. Patients were divided into two groups depending on the number of aneurysms. Demographic indicators (age, gender) and clinical-instrumental factors (comorbidities, extent of hemorrhage, severity at admission, clinical manifestations), treatment characteristics, and outcomes were analyzed using descriptive statistics and logistic regression.
Results: Comorbidities were 3.4 times more common among patients with three or more aneurysms (p=0.143). Patients in group 2 were 1.9 times more likely to be admitted with a World Federation of Neurosurgical Societies (WFNS) grade 2 (p=0.335). WFNS grade 3 at admission was observed twice as often in group 1 (p=0.447). Patients from group 1 and group 2 were equally likely to present with WFNS grade 4 (p=0.978). The probability of being admitted with a WFNS grade 5 was 1.8 times higher in group 2 (p=0.830). The presence of meningeal syndrome increased the risk of having 3 or more aneurysms by more than four times (OR 4.41, CI 0.41-47.13, p=0.21). The presence of motor impairments significantly reduced the risk of having 3 or more aneurysms (OR 0.63, CI 0.09-4.18, p=0.63). Patients in group 2 were slightly more likely to develop vasospasm than those in group 1 (OR 1.22, CI 0.34-4.31, p=0.752). The presence of comorbidities increased with the number of aneurysms (OR 3.42, CI 0.65-17.62, p=0.143).
Conclusions: The presence of comorbidities more than triples the chances of having 3 or more aneurysms. Patients with fewer aneurysms are twice as likely to be admitted in a milder condition (WFNS grade 2). The probability of severe condition (WFNS grade 5) at hospital admission for patients in group 2 is 1.8 times higher than in group 1. The likelihood of motor disorders decreases by 4.4 times with an increasing number of aneurysms. The probability of vasospasm development slightly increased with the number of aneurysms. These data emphasize the importance of a comprehensive approach to the assessment of SAH patients and the need for careful monitoring of patients at high risk of vasospasm.
Surgical treatment of meningiomas invading the superior sagittal sinus
Authors: Kvasha Michail S. , Spiridonov Anatolii V.
Published: January 2025

Objective: To investigate the impact of the degree of invasion of the superior sagittal sinus by meningiomas on the radicality of removal and to assess the risks of complications during surgical intervention for superior sagittal sinus meningiomas.
Materials and Methods: The study included 82 patients who underwent surgery at the Romodanov Neurosurgery Institute over the past 10 years (from 2013 to 2023). The cohort comprised 53 women and 29 men, with an average age of 43.4±1.7 years. Inclusion criteria are: a histologically confirmed diagnosis of meningioma and evidence of superior sagittal sinus invasion based on neuroimaging (MRI with intravenous contrast enhancement, MSCT angiography).
Results: A total of 84 surgical procedures were performed on 82 patients. Among these, 71 were primary cases (84.5%), and 13 were secondary cases (15.5%). In 7 out of 13 secondary surgeries, superior sagittal sinus invasion was first detected through neuroimaging and confirmed intraoperatively. Postoperative hemiparesis of varying degrees was observed in 41 patients (50%), with 10 cases showing an increase in neurological deficits due to surgical intervention. Motor deficits completely regressed within 3-6 months post-surgery in 28 out of 41 patients. Tumor recurrence was identified in 4 patients (4.9%) within 2.5-6 years after the primary surgery. Among these, 3 were morphologically confirmed as "anaplastic meningioma Grade III," and 1 as "atypical meningioma Grade II".
Conclusions: Meningiomas originating from the arachnoid membrane constitute a significant proportion of primary intracranial tumors, with varying degrees of venous sinus invasion. Surgical planning for meningiomas invading the superior sagittal sinus should consider the radiological classification of invasion degrees, which aids in determining the treatment strategy. MRI with intravenous contrast and MSCT angiography are crucial for identifying collateral blood flow and assessing the degree of venous sinus invasion before surgical intervention.
