Authors: Castro Mariana , Reinbold Isabelle , Nunes Caio , Darin Ticianne
Published: November 2024

Integrating music and visualization in video games is crucial in enhancing emotional storytelling and immersion. Despite the recognized power of music to evoke emotions, the deliberate combination of music and visual elements to convey specific emotions in video games remains underexplored. This study addresses this gap by proposing a set of design principles to improve the emotional impact of musical visualizations in video games. They were applied and evaluated in two visualizations, and the results showed greater alignment with the intended emotional communication. Our findings give game developers practical insights to create more emotionally engaging visual experiences.
Does it make you shiver under your skin? Stating the importance of psychophysiological measures of well-being in player's experience
Authors: Borges Bosco , Darin Ticianne
Published: November 2024

Aspects of eudaimonic well-being are already significant in Player Experience evaluation within Games User Research. To accurately assess how a player's well-being is influenced by their gaming experience, it is crucial to use not only self-report instruments, which rely on users' ability to recall and articulate their experiences, but also psychophysiological measures that can offer more reliable and nuanced data. Although further research is needed to clarify how physiological measures correspond to eudaimonic well-being in PX, this position paper argues that such understanding is essential to advance beyond superficial PX evaluation and explore how games resonate with players on a deeper level.
Immunosuppression in Infectious Diseases: Causes and Effects
Authors: Fayyaz Hajra , Zaman Atteaya , Rafiq Waheed , Hasnain Murtaza Muhammad , Ullah Imran
Published: November 2024

Immunosuppression is the reduction in the normal immune system. This suppression weakens the activation and functioning of the immune system, making individuals more susceptible to infections. By understanding immunosuppression, the recognition, management, and treatment of infectious diseases can be achieved. Generally, immunosuppression is associated with the outcome of a disease (primary or secondary immunodeficiencies). Currently, a large population is facing immunosuppression due to the exposure of therapeutic drugs. These medications modulate the immune system and effectively manage immune-related diseases, but they also increase the chance of infections. The clinical picture of infectious diseases in immune-suppressed individuals differs from the immune-competent, making the diagnosis challenging. Therefore, recognition and management of immunosuppression are necessary for preventing and curing the affected population. Herein, we will discuss an overview of immunosuppression and its role in infectious diseases, how immune cells and molecules work together to combat pathogens, the causes of immunosuppression (particularly primary immunodeficiency), and its clinical, diagnostic, and effects on human health.

Published: November 2024

Arthropods are a highly diverse group of invertebrates, found in almost every habitat and constituting more than 80% of all recognized animal species. Their diversity is evident in the numerous roles they fulfill in ecosystems, including crucial functions like pollination, decomposing organic matter, and regulating pest populations. Despite their importance in maintaining ecological balance, certain arthropods can become pests in agriculture and storage, leading to crop losses and contamination of stored products. Additionally, some arthropods, such as mosquitoes, ticks, and fleas, transmit microorganisms such as bacteria, viruses, and parasites, resulting in diseases in humans and animals. Their role as vectors of pathogens is a vital research area in veterinary medicine, focusing on understanding disease transmission mechanisms and developing control strategies. Therefore, this chapter emphasizes the importance of arthropod diversity in the veterinary context and highlights various arthropod species and the pathogens they transmit.
The Credit Boom as a Predictor of Financial Crisis
Authors: Jónsson Jón , Sigurðsson Kjartan , Kristjánsdóttir Helga
Published: November 2024

A developed nation’s rate of economic growth relies on sustaining a modern and stable financial market to facilitate consistent capital investment over the long run. Starting from the last half of the twentieth century, sustained growth in total credit availability across developed nations has been linked to increased financial market volatility and subsequent interruptions in economic growth. This study examines empirical research aimed at determining the viability of using credit availability metrics to predict financial market volatility and economic recessions. Empirical research used a macro-prudential perspective to develop a model that examines whether metrics reflecting credit booms, like the credit gap, can be reliably used to predict increased future financial market variability and reductions in economic growth. The empirical research analysis employs a receiver operating characteristic methodology that reveals how metrics of credit leveraging have become useful predictive tools as total credit has increased over time.

Why Subjectivity Reveals Man as Person
Authors: Crosby John F. ,   Philosophy Documentation Center
Published: November 2024

In this paper I ask what subjectivity is and why it reveals man as person, as Karol Wojtyla and others claim. First, I explain subjectivity, which I also call interiority, in terms of self-presence, which is a mode of relating to myself from within myself. I am present to myself as subject, not only as object. Only I can encounter myself in the intimacy of my self-presence; no other person can be present to me as I am to myself. Next, I further explore self-presence as weak or strong, calling strong self-presence recollected self-presence. Finally, I conclude by explaining how it is that recollected self-presence reveals man as person. Against the suspicion that this “turn to the subject” opens the door to a bad subjectivism, I argue that it entirely coheres with the realism of Christian philosophy.

Published: November 2024

eTwinning, Avrupa’daki okulların birbirleriyle işbirliği kurması ve projeler üretmesine olanak sağlayan, etkin katılımlı bir platformdur. Bu araştırmada, eTwinning platformunda Türkiye’nin yer aldığı projeler kapsamında, sanat eğitiminde sanal müzelerin kullanılmasının önemi ve avantajlarının vurgulanması amaçlanmıştır. Araştırmada nitel araştırma yöntemlerinden doküman inceleme ve betimsel analiz kullanılmıştır. Veri toplamada eTwinning platformunda 2009-2024 yılları arasında yayınlanan, sanal müze ve sanat eğitimi içerikli proje metinlerine ulaşılmıştır. Projelerin taraması “sanal müze” anahtar kelimesi, ”Türkiye” ve “sanat öğretim alanı” filtrelemeleriyle, 2024 yılı Temmuz ayında yapılmıştır. Türkiye’nin dâhil olduğu sanat eğitimiyle ilgili 28 projeye ulaşılmıştır. Türkiye odaklı 70.000’in üzerinde projeye sahip platformda, sanal müzelere ve sanat eğitimine yeterince yer verilmediği görülmüştür. eTwinning platformundaki sanal müze ve sanat eğitimi kapsamında geliştirilen projelerin Covid-19 pandemi döneminde ivme kazandığı ve yaygınlaştığı, 2021’den sonra ise azaldığı görülmüştür. Bu bağlamda; sanat eğitimi dersleri yeterli olmayan okullarda sosyal kulüp çalışmaları kapsamında projeler yapılabileceği; öğretmenlerin sanal müze, yabancı dil ve web2.0 araçlarıyla ilgili Milli Eğitim ve özel kuruluşların kurslarına katılabileceği; müze-okul işbirliğiyle sanal müze eğitim ve oyun etkinlikleri tasarlanabileceği önerileri verilmiştir. Bu bakış açısıyla değerlendirildiğinde, sanat eğitimi alanını desteleyecek sanal müze projeleri oluşturma noktasında, eTwinning ve diğer e-öğrenme ortamlarının yaygınlaştırılmasına yönelik eğitici eğitimleri yapılması önemlidir.

Published: November 2024

The purpose of this was to identify the effective strategies for implementing Information and Communication Technology (ICT) in Enugu State Colleges of Education. It assessed ICT implementation strategies in three colleges of education in Enugu State, concentrating on their scope, gender disparities, and techniques used across federal, state, and private colleges in the state. The study aimed to identify research variables based on behaviorist, cognitivist, and constructivist theories and their application in ICT and teacher education. The target population consisted of 2,500 100-level pre-service teachers from the three colleges of education. A proportionate stratified random sampling technique was used to select the sample from the three colleges of education in the state. 125 pre-service teachers participated in the study. The study used a descriptive survey research design, and pilot testing was conducted to ensure the validity and reliability of the questionnaire. The data were analyzed using both descriptive and inferential statistics using the Statistical Package for Social Scientists (SPSS). The results showed that ICT implementation in colleges of education is not fully utilized, resulting in low educational objectives. Based on the findings, it is recommended that the government, curriculum planners, in-service and pre-service teachers, and educational institutions be more proactive in adopting strategies that enhance the effective implementation of ICT in colleges of education.

Published: November 2024

Aim. To identify the underlying causes of complications in distinguishing the origin of head masses through a comparative analysis of CT findings and clinical observations.Materials and methods. A retrospective analysis of radiological imaging for pancreatic cancer (36 cases) and chronic pancreatitis (24 cases) was conducted. Pancreaticoduodenectomy was performed in 23 cases (14 for cancer and 9 for chronic pancreatitis), while drainage interventions were carried out in 35 cases.Results. On pre-contrast images, pancreatic cancer appeared isodense in 97 % of cases, while in the arterial phase, it was hypodense in 94 %. For chronic pancreatitis, these percentages were 67 % and 46 %, respectively. The density curves of the pancreatic head and normal parenchyma were nearly identical across all phases, but the density gradient difference was more pronounced in pancreatic cancer (27 HU compared to 15 HU). Bile duct strictures with interruption were observed more frequently in cancer (44 %), along with arterial vessel invasion (25 %). CT signs indicative of chronic pancreatitis included wirsugolithiasis (21 %) and portal hypertension (42 %). Both diseases exhibited similar CT features, such as cystic lesions, peripancreatic tissue infiltration and peripancreatic lymphadenopathy. In six cases of pancreatic head cancer and seven of chronic pancreatitis, identical pathological changes were identified during intraoperative revision: pseudocysts (2 in cancer and 4 in chronic pancreatitis), infected necrosis and abscesses (3 and 2, respectively) and similar views of the head mass cut plane (1 each).Conclusion. The overlap in CT features due to similar pathomorphological changes presents an objective challenge in differentiating pancreatic head masses
Integral haematological indices and homocysteine in posthepatectomy liver failure
Authors: Dunaevskaya S. S. , Kosik A. A.
Published: November 2024

Background. The increase in the volume and number of hepatic surgeries is causing a rise in the frequency of postoperative complications, such as acute posthepatectomy liver failure.Aim. This article investigates changes in integral haematological indices and plasma homocysteine depending on the degree of development of posthepatectomy liver failure.Materials and methods. The article presents the results of the study of the value of leukocyte indices of cellular reactivity and plasma homocysteine level in 40 patients with different classes of acute posthepatectomy liver failure (PHLF). Patients were divided into three groups: those with postoperative class A, B and C PHLF. Data were analysed before surgical intervention, postoperatively and upon discharge.Results. A comparison of the average leukocyte indices in groups B and C of PHLF before surgery, postoperatively and upon discharge revealed a rise in most metrics. The notable increase in indicators of the progression and extent of endotoxicosis and inflammatory response suggests their potential use as screening markers for diagnosing and predicting this complication. Moreover, the considerable rise in plasma homocysteine levels in B and C PHLF groups during the postoperative phase indicates a disruption in the synthesis of the acid and correlates with functional liver failure.Conclusion. The haematological intoxication indices and plasma homocysteine levels ensure early detection of inflammatory response development and are diagnostically significant in identifying acute PHLF.

Published: November 2024

Aim. This article aims to assess the effectiveness of uroflowmetry in detecting residual urine and to investigate the relationship between the sensation of incomplete bladder emptying, as measured by the IPSS questionnaire, and the presence of residual urine.Materials and methods. A cohort of patients treated at the Urination Pathology Centre (Vladivostok) for benign prostatic hyperplasia was observed and data were collected. Patients ranged in age from 50 to 73 years (with an average age of 60.5 ± 8.2 years) and were observed during from 2 to 24 months (with an average of 8.4 ± 5.5 months).Results. The analysis of ultrasound data and uroflowmetry results demonstrates convincingly that the SIGMA uroflowmeter can reliably detect residual urine with a high degree of accuracy (p < 0.01). However, during the study, no consistent correlation was found between the symptom of feeling of incomplete bladder emptying, as assessed by the IPSS questionnaire, and the presence of residual urine detected by the SIGMA uroflowmeter.Conclusion. Uroflowmetry conducted with the SIGMA uroflowmeter reliably identifies instances of incomplete bladder emptying, as evidenced by comparison with ultrasound data. At the same time, clinical assessment using the IPSS charts, particularly for the symptom of incomplete bladder emptying, does not adequately indicate the presence of residual urine. Uroflowmetry offers a means to identify incomplete bladder emptying and measure residual urine volume without requiring specialised equipment or medical personnel, thus broadening the diagnostic scope for both conservative and surgical treatment approaches.

Background. According to the literature, acromioclavicular dislocations rank third in frequency among all dislocations within the musculoskeletal system. The social significance of acromioclavicular (AC) joint injuries lies in that the majority of affected individuals are part of the working-age population, typically aged 25 to 45 years, frequently involved in physically demanding occupations and high-level sports.Aim. This article seeks to compare various surgical treatment methods for AC dislocations. Materials and methods. This study analyses current Russian and international literature sources regarding the surgical treatment of AC dislocations. The information sources were examined using the eLibrary and PubMed search engines.Results and discussion. In current clinical practice, surgical methods are typically preferred when considering treatment approaches for AC dislocations. This preference stems from the significant advantages associated with surgery, including a shorter rehabilitation period and high patient satisfaction with long-term treatment outcomes, despite the risks of postoperative complications.Conclusion. The most promising methods for stabilising the AC joint include the use of a hookshaped plate and the button suture. While a hook-shaped plate offers greater stability compared to the button suture, it necessitates informing the patient about the need for plate removal three months post-surgery to reduce the risk of osteoarthritis development. On the other hand, the button suture does not require additional surgical procedures for implant removal but may result in less rigid fixation, potentially leading to recurrence of dislocation.

Published: November 2024

Background. Tenosynovitis and longitudinal rupture of the tendon of the long fibular muscle linked to hypertrophy of the fibular tubercle of the calcaneus are relatively uncommon conditions. The literature has documented isolated clinical cases, but there is a lack of comprehensive research on diagnosing and treating these ailments.Aim. This article seeks to present an effective surgical treatment option along with mandatory diagnostic blockade for a patient with hypertrophic fibular tubercle complicated by tenosynovitis and longitudinal rupture of the tendon of the long fibular muscle.Case description. This article describes a rare clinical case involving tenosynovitis and longitudinal rupture of the tendon of the long fibular muscle, which is associated with hypertrophy of the fibular tubercle of the calcaneus. After examination, diagnostic blockade and unsuccessful conservative therapy, the decision was made to pursue surgical intervention.. The surgical procedure involved resection of the fibular tubercle and tubularisation of the tendon of the long fibular muscle. Eight months after treatment, there was no recurrence of symptoms.Conclusion. This clinical case illustrates the successful outcome of surgical intervention for a patient with hypertrophic fibular tubercle tenosynovitis, and longitudinal rupture of the tendon of the long fibular muscle. Diagnostic blockades can be beneficial for identifying the primary cause of foot pain and devising appropriate treatment strategies.

Published: November 2024

Aim. To evaluate the effectiveness of the cultural and linguistic adaptation of the Fecal Incontinence Quality of Life Scale (FIQOL) for the Russian-speaking population.Methods: A cultural and linguistic adaptation of the FIQL questionnaire was performed in accordance with international guidelines. This process included several key steps: professional translation of the questionnaire, back translation, and critical discussion within an interdisciplinary council comprising translators, linguists, psychologists, doctors, and patients. Preliminary testing and reliability assessment were also conducted. The results of the preliminary testing are presented in this article. A total of 26 patients who had undergone surgical treatment for anal incontinence (sphincterolevatoroplasty) between 2016 and 2022 participated in the preliminary testing phase.Results. The result of the cultural adaptation is the Russian language version of the Fecal Incontinence Quality of Life Scale (FIQOL), which has undergone all the aforementioned stages with corrections and comments in the order of the council of doctor-translator-psychologist-patient. The average time elapsed from the moment of surgery to the survey was 32 months (SD = 20). The average overall score of the questionnaire was 3.2 (SD = 0.62), the average score on the ‘Lifestyle’ scale was 3.3 (SD = 0.74), the average score on the ‘Behaviour, daily worries’ scale was 3.2 (SD = 0.65), the average score on the ‘Depression and self-perception scale was 3.4 (SD = 0.91) and the average score on the ‘Shame’ scale was 3.2 (SD = 0.71). The assessment of the reliability of the questionnaire, as shown by the alpha-Kronbach coefficient, was 0.94, which corresponds to the assessment of ‘very good reliability’.Conclusion. The presented data show that the Russian version of the Fecal Incontinence Quality of Life Scale (FIQOL) is adapted for use by Russian-speaking patients and specialists, is reliable, and can be used as a primary tool for assessing the quality of life of patients with anal incontinence.

The review provides data on the causative agents of periprosthetic infection, as well as features of its treatment, prevention, and diagnosis. It considers modern data on the epidemiology and risk factors of this complication. The most common cause of revision operations after endoprosthesis is periprosthetic infection, followed by aseptic loosening of the endoprosthesis. Independent risk factors have been identified, including congestive heart failure, chronic lung diseases, preoperative anemia, depression, kidney disease, pulmonary circulatory disorders, psychosis, metastatic tumors, and diseases of peripheral vessels and heart valves.Conclusion. At present, there is a growing trend in the number of endoprosthetic surgeries for large joints, leading to an increase in revision interventions. Consequently, the number of periprosthetic infections is also rising, highlighting the importance and potential of research focused on controlling infectious agents and improving prevention and treatment methods.

The literature review examines the significant role of adipose-derived stem cells (ASCs) as a segment of mesenchymal stem cells in modern medicine. ASCs possess unique characteristics, such as a high ability to differentiate and regenerate, making them a valuable resource in regenerative medicine and therapy. The review focuses on methods for isolating and cultivating ASCs and emphasizes the importance of adhering to standards for monitoring the cultivation and storage processes of stem cells. The molecular and cellular characteristics that enable the use of ASCs in various medical fields, including the treatment of cardiovascular and neurological disorders, reconstructive surgery, and tissue engineering, are described. The ability of ASCs to differentiate into diverse cell types, including osteocytes, adipocytes, neural cells, vascular endothelial cells, and cardiomyocytes, underscores their potential in treating a wide range of diseases.The review addresses critical ethical and safety considerations related to the use of ASCs, particularly their interaction with tumor cells. It emphasizes the need for further in-depth, multidisciplinary studies of ASC interactions with host cells to ensure their safe and effective use in clinical practice. Evidence is presented for the potential of ASCs in treating long-term non-healing diabetic ulcers and wounds by enhancing epithelialization and accelerating granulation tissue formation. Additionally, their ability to reduce the number of fibroblasts in hypertrophied scars is highlighted.In conclusion, the review underscores the significance of ASCs as one of the most promising areas in modern biomedicine and regenerative medicine. It notes that further research on these cells may lead to new approaches in the treatment and prevention of various diseases.
Preoperative bleeding risk assessment in cardiac surgery patients
Authors: Zyuzin V. S.
Published: November 2024

Aim: To investigate the role of bleeding risk scores, personal and family medical history, and previous bleeding incidents in assessing the impact on the risk of all possible complications, including mortality, in adult patients following cardiac surgery.Methods. The search for publications was conducted using the PubMed, Transfusion Evidence Library, and eLibrary.ru databases, covering the period from 2019 to 2023. Search terms included: ‘bleeding risk assessment scales in adult cardiac surgery’, ‘preoperative anemia in adult cardiac surgery’, and ‘transfusion of red blood cell-containing components in cardiac surgery adults’. Duplicate articles were manually excluded. An additional search was performed among the reference lists of selected publications.Results. A total of 2,011 publications were found. In the first stage of selection, clinical studies, meta-analyses, randomized controlled trials, reviews, and regular reviews without language restrictions were considered based on the content of the abstract. In the second stage, for studies that passed the initial screening, decisions were made based on an assessment of the full-text versions, which presented the consequences of preoperative anemia, postoperative bleeding, and transfusion therapy in adult cardiac surgery patients. Ultimately, 40 publications were included in the review.Conclusion. Preoperative bleeding risk assessment is a multimodal, interdisciplinary challenge that necessitates a patient-centered approach. It should commence at the preparatory stage and involve primary care physicians, cardiologists, surgeons, anesthesiologists, laboratory diagnostic specialists, and transfusiologists. The cornerstone of this process is the thorough collection of individual and family medical histories. Obtaining detailed information through patient involvement, utilizing bleeding risk rating scales, reviewing previous bleeding incidents, and supporting these findings with laboratory test data represent the most scientific approach to developing an individualized management plan for patients at risk of bleeding.

The paper describes a unique clinical case involving a patient with two tumours of mesenchymal and epithelial origin, along with ectopic endometriosis located within the cecum. This combination of pathologies resulted in colonic intussusception and subsequent colon-small intestine obstruction due to a cecal lipoma, compounded by colorectal cancer in the same area with local endometriosis foci. The surgical intervention involved laparoscopic resection of the terminal ileum, cecum, ascending, transverse, and descending colon, along with D2 lymphadenectomy and laparoscopically assisted ileosigmoid anastomosis. The patient was discharged in satisfactory condition on the 7th day post-surgery. This clinical observation garnered significant attention due to its atypical presentation of a rare complication, initially leading to a misdiagnosis and necessitating extensive intestinal resection for cancer under urgent circumstances with adequate lymph node dissection. Furthermore, the favourable treatment outcome despite the long-term presence of intussusception for at least one month underscores the noteworthy aspect of this case.

Background. The incidence of disease relapse after primary antireflux surgical treatment ranges from 4 to 24 %, with up to 9 % of cases requiring revision surgery. Several studies demonstrate that the results of operations for recurrent hiatal hernia are less satisfactory compared to the primary procedure, especially after multiple interventions.Aim. To propose a technique for laparoscopic redo fundoplication using a novel method, to evaluate short-term and long-term results after repeated surgical treatment of patients with recurrent hiatal hernia and GERD, and also to propose a classification of relapses of GERD and hiatal hernia.Material and methods. The prospective study included data from 31 patients diagnosed with recurrent GERD and hiatal hernia. Laparoscopic redo fundoplication was used as a surgical method. Intraoperatively, technical errors of the previous operation were identified. The classification of relapses was conducted using the author’s method. Quality of life indicators using specialised questionnaires before surgery were: GERD-Q — 12.1 ± 2.82, GERD-HRQL — 26.12 ± 8.31, GSRS — 44.26 ± 10.21.Results. There were no access conversions. The average duration of the operation was 141.21 minutes, blood loss was 81.40 ml, intraoperative complications in 4 (9.7 %) patients were eliminated intraoperatively, postoperative complications according to Clavien-Dindo ≥ 3 were diagnosed in one patient (pneumothorax), performed drainage of the pleural cavity. In 18 (58 %) patients, technical errors were identified that were made during the previous antireflux intervention. Quality of life indicators using specialised questionnaires six months after surgery were: GERD-Q — 2.1 ± 1.31, GERD-HRQL — 4.31 ± 2.98, GSRS — 17.02 ± 6.18. During the follow-up examination, 27 (87 %) patients noted complete recovery, as well as the absence of the need for PPI and prokinetic therapy.Conclusion. The results of the study confirm the effectiveness, functionality and safety of laparoscopic redo fundoplication as the main treatment for this disease.

Aim. To analyse the results of surgical treatment of osteomyelitis in patients with diabetic foot.Methods. A retrospective analytical study was conducted to assess the outcomes of surgical treatment for osteomyelitis in diabetic foot patients. The study analysed 28 patients with osteomyelitis classified as Grade III according to the Wagner classification. The average age of the participants was 62.5 ± 14.5 years, and the mean duration of diabetes mellitus was 8.2 ± 5.5 years. The cohort consisted of 16 men (67.1 %) and 12 women (32.9 %). All patients presented with a single osteomyelitic lesion located in the anterior region of the foot. The underlying causes of osteomyelitis included trophic ulcers and complications such as abscesses of the toes and phlegmon of the foot, which developed secondary to the trophic ulcers.Results. In the group of patients who underwent both autopsy and drainage of abscesses and phlegmon, followed by one-stage amputation of one or more toes with radical resection of the corresponding metatarsal heads, the average number of hospital bed days was 31.9 ± 15.7. In contrast, the group of patients who were admitted without purulent necrotic complications and underwent one-stage amputation of one or more toes with radical resection of the metatarsal heads had an average of 13.4 ± 2.1 bed days.Conclusion. Prolongation of medical treatment in patients with osteomyelitis of the diabetic foot, leading to the occurrence of purulent-necrotic complications, doubles the length of hospital stay, which entails an increase in treatment costs.
