Relevance. The limited selectivity of antitumor therapy for central nervous system neoplasms entails the risk of dental morbidity in patients.

The aim of the study is to assess the severity of damage to the dental hard tissues in patients with tumors of the posterior cranial fossa (medulloblastoma, astrocytoma) and other tumors of the central nervous system.

Materials and methods. Three comparison groups were established based on the toxicity profiles of antitumor therapy among 251 patients at the "Russian Field" treatment and rehabilitation scientific center, to assess the characteristics of oral health status. The assessment of oral health status included diagnosing the carious process and calculating the DMFT index. The degree of damage to the dental hard tissues was evaluated on a four-point scale. The clinical manifestations of oral cavity pathology were compared using the Z-criterion for multiple pairwise comparisons of data, with adjustments for multiple testing (Multiple pairwise comparison Z-test for proportions with multiple testing correction) using the free R software version 3.5.2. The null hypothesis of equal indicators in the compared groups was rejected with a 95% confidence probability when comparing groups of patients.

Results. Dental hard tissue pathology was significantly more prevalent in patients with medulloblastoma compared to those diagnosed with astrocytomas and other central nervous system tumors. Additionally, the prevalence of dental hard tissue pathology progressively decreased as the observation period following the completion of antitumor remission was extended.

Conclusion. The most severe damage to dental hard tissues is observed in patients with medulloblastoma, who undergo more intensive antitumor therapy compared to those with CNS tumors of other histological types.

Background

UK cancer deaths remain high; primary care is key for earlier cancer diagnosis as half of avoidable delays occur here. Improvement is possible through lower referral thresholds, better guideline adherence, and better safety-netting systems. Few interventions target whole practice teams. We developed a novel whole-practice team intervention to address this.

Aim

To test the feasibility and acceptability of a novel, complex behavioural intervention, ‘ThinkCancer!’, for assessment in a subsequent Phase III trial.

Design & setting

Pragmatic, superiority pilot randomised controlled trial (RCT) with an embedded process evaluation and feasibility economic analysis in Welsh general practices.

Method

Clinical outcome data were collected from practices (the unit of randomisation). Practice characteristics and cancer safety-netting systems were assessed. Individual practice staff completed evaluation and feedback forms and qualitative interviews. The intervention was adapted and refined.

Results

Trial recruitment and workshop deliveries took place between March 2020 and May 2021. Trial progression criteria for recruitment, intervention fidelity, and routine data collection were met. Staff-level fidelity, retention, and individual level data collection processes were reviewed and amended. Interviews highlighted positive participant views on all aspects of the intervention. All practices set out to liberalise referral thresholds appropriately, implement guidelines, and address safety-netting plans in detail.

Conclusion

‘ThinkCancer!’ appears feasible and acceptable. The new iteration of the workshops was completed and the Phase III trial has been funded to assess the effectiveness and cost-effectiveness of this novel professional behaviour change intervention. Delivery at scale to multiple practices will likely improve fidelity and reach.

Published: May 2024

This research aims to create a system that will provide information about predicting the amount of production to help related parties in determining the amount of production, in addition to seeing the accuracy of the use of methods in predicting the amount of production. Production activities are a series of activities carried out to turn raw materials into products that can be marketed and sold. One of the things involved in this process is the amount of raw materials that will be made into finished products. A calculation process is needed to predict the number of products to be produced to minimize production costs.  The method used for the prediction process is the Fuzzy Tsukamoto method, where this method overcomes uncertainty and complexity in decision making. Calculation of errors in predicting is used mean absolute percentage error (MAPE), and for system design an object approach is used using Unified Modeling Language (UML) tools. The results of the study state that system testing is worth 92%, meaning that the system can be used as needed, and for the method used to get an error value of 10.62% so that the Fuzzy Tsukamoto method can be used to predict the amount of production.

Digital technologies are the need of the hour in the accounting field in the current 4th industrial revolution. Digital transformation positively and negatively affects all areas of business. The new technologies are disrupting the accounting field. Digital transformation is pressuring accounting practitioners and graduates to learn digital skills but despite the emergence of new technologies in the accounting field, it is unfortunate that not much is known concerning the impact of digital technologies in the accounting field. This paper critically examines the contribution of digital technologies in accounting and reporting focusing on its advantages, limitations, and possible risks. A systematic literature review methodology, inductive approach and thematic analysis was adopted. Despite the limitations of digital technologies in accounting like poor data governance systems, cyber-attacks, and infringement of privacy, it emerged that digital technologies play a significant role in the provision of real-time accounting data and information, automation of routine accounting activities, visualization of accounting information, augmenting big data analysis, and eliminating errors as well as improving efficiency in accounting. Digital technologies are transforming the accounting arena by boosting efficiency and effectiveness. We recommend accounting professionals, practitioners and policy makers should invest in new digital technologies.

Published: May 2024

In the contemporary world, where globalization is intensifying, the significance of international agreements and their impact on national legal systems is increasing. International agreements serve not only as the foundation for regulating interstate relations but also as a crucial tool for unifying legal norms, promoting the protection of human rights, sustainable development, economic cooperation, and environmental protection. The analysis of theoretical aspects demonstrates that international agreements are a crucial element of the global legal system, providing a basis for international cooperation. Studying the practical application of international agreements in national legal systems has revealed various mechanisms for implementing and adapting international norms to domestic legislation. Discussions on the challenges of compatibility, sovereignty, the effectiveness of international agreements, and the adaptation of international norms to the national context have highlighted the need to balance the requirements of international law with national peculiarities. The study's conclusions emphasize the importance of integrating global norms from international agreements into national legal systems. Further research should focus on developing flexible mechanisms for implementing international agreements that consider the specificities and needs of different states. Additionally, it is important to analyze the impact of technological development on international law.

Authors: Michielin Mariane de Castro , Nascimento Taís Lages do , Leite Nicoly Monique Cândido Cordeiro , Teixeira Gabriela Peron , Reis Analú Holanda Jordão dos
Published: May 2024

A hanseníase é uma doença infecciosa curável, causada pelo Mycobacterium leprae, que afeta principalmente a pele e os nervos periféricos, podendo também comprometer mucosas, com predileção pelo trato respiratório superior. Apesar de ser considerada erradicada pela OMS em 2000, ainda é prevalente em países em desenvolvimento, causando preocupação devido ao seu impacto físico, social e psicológico. A classificação da hanseníase em seis categorias, como Tuberculóide (TT) e Virchowiano (LL), ajuda a entender suas diferentes apresentações clínicas. Os sintomas variam desde sensibilização ou aumento dos nervos periféricos até lesões cutâneas e neurológicas graves, como paralisia facial. O diagnóstico precoce é essencial para prevenir complicações e interromper a transmissão, sendo feito por meio de exames clínicos, bacteriológicos, imunológicos e histopatológicos, com destaque para a baciloscopia e a biópsia de pele. O tratamento é realizado com uma combinação de medicamentos, como Rifampicina, Clofazimina e Dapsona, administrados por um período de seis a doze meses, dependendo da classificação da doença. Reações inflamatórias, como a reação reversa do sistema imunológico, podem ocorrer durante o tratamento e exigem manejo adequado. A OMS lançou uma estratégia global para acelerar o controle da hanseníase, com foco na redução do número de casos e deformidades físicas, especialmente em crianças. Em suma, o diagnóstico precoce, o tratamento adequado e o apoio psicossocial são fundamentais para o controle eficaz da hanseníase e a melhoria da qualidade de vida dos pacientes.

Published: May 2024

Reversal of endothelial cell (EC) dysfunction under high-glucose (HG) conditions to achieve angiogenesis has remained a big challenge in diabetic ulcers. Herein, exosomes derived from medicinal plant ginseng (GExos) were shown as excellent nanotherapeutics with biomimetic cell membrane-like structures to be able to efficiently transfer the encapsulated active substances to ECs, resulting in a marked reprogramming of glycolysis by up-regulating anaerobic glycolysis and down-regulating oxidative stress, which further restore the proliferation, migration, and tubule formation abilities of ECs under HG conditions. In vivo, GExos enhance the angiogenesis and nascent vessel network reconstruction in full-thickness diabetic complicated skin ulcer wounds in mice with high biosafety. GExos were shown as promising nanotherapeutics in stimulating glycolysis reprogramming-mediated angiogenesis in diabetic ulcers, possessing wide application potential for reversing hyperglycemic dysangiogenesis and stimulating vascular regeneration.

The paper presents a new mathematical model for the solution of a static symmetric boundary-value problem for a layer weakened by a through hole with ends covered with a diaphragm. A new method based on a system of three singular integral equations has been developed and tested numerically. As a result of a high-precision numerical study, it was found that with an increase in the thickness of the layer, an increase in the relative circumferential stress occurs. With a decrease in one of the radii of the elliptical hole, an increase in the relative circumferential stress is also observed. The paper presents the respective dependency graphs. Keywords: three-dimensional boundary-value problems, singular integral equations, numerical experiment, static stretching–compression, a through hole.

Published: May 2024

We address the problems of causal structure reconstruction given conditional independence facts when latent confounders are allowed. We examine the conditions that allow one to partially or fully identify authentic causal links and latent confounders. The updated implicative rules for orienting edges under confounding are suggested. As demonstrated, it is possible to construct the new rules, which can reveal confounded causal edges and bows. The rules rely on facts of the absence of certain authentic edges (such facts may be justified by non-independence constraints, like Verma constraint, or subject-based requirements). Keywords: causal relation, d-separation, conditional independence, latent confounder, edge orientation, bow (arc).

Published: May 2024

This research focuses on exploring and understanding the role of Habit in sustaining the adoption and continuous use of AIKU technology as its primary objective. The UTAUT2 model was chosen, emphasizing the Habit variable (HT) along with 6 other key variables: Performance Expectancy (PEX), Effort Expectancy (EEX), Price Value (PV), Social Influence (SIN) on Behavioral Intention (BIN), and User Behavior (UB), with the addition of external variables Perceived Risk (PR) and moderating Gender and Experience. The research methodology involves data analysis using SmartPLS 4.0 software and the UTAUT2 model as the framework and theoretical foundation. Survey data were collected from 414 AIKU users in Indonesia. Findings based on data analysis indicate that factors such as PE, EE, and PV significantly positively influence BI to continue using AIKU. In addition to filling gaps in knowledge regarding the role of Habit in air quality technology literature, another finding is that H significantly positively influences BIN and UB, while BIN significantly positively influences UB. This research’s novelty and primary contribution lie in the implications concerning the crucial emphasis on the Habit factor in sustaining AIKU usage. The development implications underscore the importance of psychological factors in technology acceptance and retention, providing valuable insights for future strategy and policy development. Limitations of this research lie in the focus on the AIKU system affecting result generalization. Future research, expanding coverage, considering air quality system variations, employing diverse data collection methods such as in-depth interviews are recommended.

Correlating Gas/Particle-Phase Concentration of Indicator Polychlorinated Biphenyls with Meteorological Factors in Bayburt, an Important University City of Turkey
Authors: Paloluoğlu Cihan
Published: May 2024

This study was carried out in two seasons in Bayburt University Baberti Campus (BUBC) in Bayburt city, which is an important university city in Turkey. Gas and particle phase atmospheric concentrations of Urban atmospheric Indicator Polychlorinated Biphenyls (i-PCBs: PCB#28, 52, 101, 118, 138, 153, 180) were determined at first. Then, by using different methods, the interactions between i-PCB concentrations and meteorological factors were investigated. Gas and particle phases of atmospheric i-PCB samples were collected using a high-volume air sampler (HVAS) in BUBC . Following this stage, the samples were analyzed in a gas chromatography-mass spectrophotometer (GC-MS) by passing through appropriate extraction steps. According to the data obtained, the average gas phase ∑i-PCB concentration for the summer month was determined to be 11.314 pg/m3 during the sampling period while the average particle phase ∑i-PCB concentration was found to be 2.145 pg/m3. The average gas phase ∑i-PCB concentration was found to be 4.582 pg/m3 for the winter period while it was found to be 1.756 pg/m3 for the average particle phase ∑i-PCB concentration. In addition, the average total concentrations of i-PCBs were calculated to be 19.797 pg/m3. It was determined that meteorological factors especially temperature (from the Clausius–Clapeyron equation), wind velocity and direction, and rainfall have significant impacts on i-PCB concentration and its distribution. In light of these data, i-PCB concentrations determined in the gas phase were found to be higher than those in the particle phase. In addition, concentration rates determined in summer months were calculated to be higher compared to those calculated for winter months.
Make Me Black Music Video: A Project of DIVAS for Social Justice
Authors: JAMES CLARISA
Published: May 2024

The Make Me Black Music Video is a collaborative project created in 2022 by students of the STEAM for Social Change program to honor Black History Month. The initial idea for the music video was inspired when one of the STEAM for Social Change facilitators first heard the song while listening to a local Minnesota radio station, Purple Current. Also available as an internet stream, the Purple Current radio station focuses on Black music that honors the legacy of the late musician Prince Rogers Nelson. As the facilitator listened to the song Make Me Black, originally performed by Minnesotan Ashley Dubose, they saw it as a medium for teaching students the importance of seeing themselves as beautiful and joyful, while instilling pride in where they come from. Before creating their music video, students engaged in an 8-week session where they learned the history of MTV, including how the channel failed to play any artists of color until Michael Jackson’s Thriller became a global phenomenon in 1983. Students also analyzed the song lyrics, created storyboards using Polaroid cameras, and learned about the fundamentals of music video production. The original music was produced by Rich Lee and performed by Ashley DuBose. The students’ music video was filmed on location at their school sites and the DIVAS for Social Justice makerspace. It also features the artwork of educator and artist, Adam Johnson.
Algunos aportes del pensamiento situado para pensar procesos sociales
Authors: Díaz Rojo María Florencia
Published: May 2024

Este artículo intenta recuperar los postulados del Pensamiento Situado, sistematizando lecturas de diferentes autores pero sobre todo de la mano del Dr. Alejandro Auat. Este brinda un compilado muy amplio de diversas corrientes teóricas que permiten comprender la idea de situacionalidad, a las cuales denomina como constelación conceptual. Entendiendo que la idea de situacionalidad va más allá de la clara referencia a las circunstancias que imprimen una particularidad determinada a cada pensamiento, es decir a un pensamiento producido en un contexto determinado, sino que se trata de sumarle a ello una mirada crítica, gnoseológica y axiológica del punto de vista desde donde se habla y se piensa. Esto a su vez implica un posicionamiento político, es decir una toma de posición y va a contramano del pensamiento dominante en las ciencias sociales.
Luego de revisar las bases de este pensamiento se intentará hacer una breve síntesis de algunos aportes que brinda este a los y las investigadores para pensar diferentes procesos sociales dentro del campo de las ciencias sociales. Por lo tanto, cabe señalar que este no será un análisis exhaustivo que recupere todos los aportes posibles,  sino los que se consideran centrales.

Prospects of Using PCSK9 Inhibitors for Acute Coronary Syndrome
Authors: Namitokov A. M. , Zafiraki V. K. , Karabakhtsieva K. V.
Published: May 2024

Proprotein convertase subtilisin/kexin type 9 (PCSK9) is an enzyme involved in the regulation of blood cholesterol levels by binding to low-density lipoprotein receptors and promoting their degradation. Pivotal studies have shown that PCSK9 inhibition by monoclonal antibodies, alirocumab and evolocumab, and the small interfering RNA (inclisiran) reduces the risk of cardiovascular diseases in individuals with coronary heart disease. However, the place of the PCSK9 inhibitors in treatment of patients with acute coronary syndrome has not been determined yet. The article discusses studies on the addition of PCSK9 inhibitors to therapy during the acute phase of myocardial infarction as well as pathophysiological prerequisites for their use.

In recent years, there has been an upward trend in the urolithiasis incidence worldwide and an increase in the recurrence of stone formation. Urolithiasis prevalence rates range from 1% to 20%. In some countries, there is an increase in rates up to 37%. Stones are classified into those caused by infections, non infectious causes, and genetic diseases. Alteration in urine microbiome plays a significant role in the infection stone formation. Our objective was to review the current literature on the role of bacteria in the formation of kidney concrements. The gained knowledge could be used to explore new possibilities and improve the understanding of stone formation. We analyzed articles on the composition of the urine microbiome and kidney stones.

Authors: Bykov Y. V. , Obedin A. N. , Muravyova A. A. , Zinchenko O. V.
Published: May 2024

Background: Diabetic ketoacidosis (DKA) is an acute and severe complication of type 1 diabetes that is highly prevalent in children and adolescents. Intravenous (IV) insulin infusion is the mainstay of DKA treatment in the intensive care unit; however, standard-dose (0.1 U/kg/h) insulin infusion increases the risk of cerebral edema.

Objective: To compare the efficacy and safety of low-dose (0.05 U/kg/h) vs high-dose (0.1 U/kg/h) IV insulin infusion in children and adolescents treated for DKA. Materials and methods: Our randomized single-blind study included 86 patients aged 5 to 14 years urgently hospitalized with symptoms of DKA. Group 1 comprised 40 children who received IV insulin at the low rate (0.05 U/kg/h), whereas group 2 included 46 children who received IV insulin at the standard rate (0.1 U/kg/h). During the treatment we compared the time to DKA resolution and blood glucose level decrease to 15 mmol/L and recorded cases of hypoglycemia, hypokalemia, and papilledema. The MannWhitney test was used to determine whether differences were statistically significant.

Results: There was no difference between groups 1 and 2 in DKA treatment duration. The blood glucose level was found to decline to 15 mmol/L more slowly in children who received IV insulin at 0.05 U/kg/h. Hypoglycemia, hypokalemia, and papilledema were more common in the standard-dose (0.1 U/kg/h) group.

Conclusions: The low-dose IV insulin infusion (0.05 U/kg/h) is safer in terms of complications (cerebral edema) associated with pediatric DKA treatment in the intensive care unit and not inferior to the standard recommended dose (0.1 U/kg/h) in efficacy.

Background: Synthetic sling surgery has become quite a popular method for stress urinary incontinence treatment over the past quarter century. The effectiveness of eliminating urinary incontinence is estimated by various authors from 70% to 95%; however, urinary disorders often develop after surgery. In some cases, conditions underlying incomplete bladder emptying occur. In addition, clinical symptoms of imperative urination disorders appear. They are generally known as de novo and manifest with urinary frequency, imperative urges, and urge incontinence. Literature shows that obstructed urination in women is also common, and synthetic sling surgery is indicated.

Objective: To assess the incidence of obstructed urination and development of incomplete bladder emptying in female patients with synthetic tapes placed under the urethra.

Material and methods: We observed a group of female patients examined at the Center for “Urination Pathology” (Vladivostok, Russian Federation) for stress urinary incontinence. The mean age in the group (40 cases) was 53.4±4.2 years (range, 35-68 years). All the patients underwent trocar synthetic sling surgery. Home uroflowmetry was performed before surgery and within 3 months after discharge.

Results: After synthetic sling surgery, the urination obstruction and probability of residual urine formation were found to increase. At the same time, there was a weak association between preoperative obstruction and difficulty after synthetic tape placement. We measured incomplete bladder emptying using a new technique: by original Russian UFM “SIGMA” uroflowmeter.

Conclusions: The study data support the need for widespread use of a new technique of noninvasive urodynamics for residual urine determination. The use of a 2-sensor uroflowmeter with an original algorithm for processing urine flow records is a fundamentally new tool for assessing the functional state of the lower urinary tract that can detect residual urine with a probability of 0.95 and help solve a rather complex clinical problem.

Background: Cancer therapy-related cardiac dysfunction (CTRCD) is a new term that encompasses a wide range of potential manifestations and is etiologically associated with a wide variety of cancer treatments. Detection of early subclinical cardiac dysfunction is of great clinical importance.

Objective: To assess subclinical CTRCD in women with HER2-positive locally advanced or metastatic breast cancer undergoing a course of anthracyclines (doxorubicin), docetaxel, and trastuzumab. We prospectively enrolled women aged 18-75 years with an established diagnosis of HER2-positive locally advanced or metastatic breast cancer across 3 centers.

Material and methods: We monitored 122 women with HER2-positive locally advanced or metastatic breast cancer undergoing a course of anthracyclines (doxorubicin), docetaxel, and trastuzumab using speckle-tracking echocardiography. Based on the treatment protocol, we formed 3 comparison blocks: block 1 (chemotherapy: doxorubicin+cyclophosphamide); block 2 (chemotherapy+targeted therapy: docetaxel+trastuzumab), and block 3 (targeted therapy: trastuzumab).

Results: The rate of subclinical CTRCD detection was high and exceeded 20%-30% in all comparison blocks after the 3rd course of chemotherapy, chemotherapy+targeted therapy, and targeted therapy. The rate of subclinical CTRCD increased significantly from the 1st to the 2nd, from the 2nd to the 3rd, from the 3rd to the 4th therapy courses in each block. Comparisons between the blocks were significant only after the 4th course of chemotherapy and the 4th course of targeted therapy (Yates-corrected chi-square, P=.0394); all the other comparisons between the blocks were not significant in terms of subclinical CTRCD rate.

Discussion: Given the growing number of patients with breast cancer, such frequent monitoring of the cardiac function is likely to improve the quality of cancer treatment and might have a positive impact on the overall survival of patients with breast cancer.

Conclusions: Criteria for frequency of echocardiographic monitoring of cardiac dysfunction in patients with malignant tumors, especially with HER2-positive breast cancer, should be revised.
Cytomegalovirus Colitis: A Case Report

We report a case of cytomegalovirus (CMV) colitis. The patient (a woman with a provisional diagnosis of Crohn disease) presented with severe abdominal pain, diarrhea, and weight loss. Despite difficulties in differential diagnosis, we were able to make the correct diagnosis based on findings of the histological examination of the biopsy specimens obtained during colonoscopy: intranuclear inclusions characteristic of CMV and specific CMV-associated changes in the intestinal mucosa. This case highlights the importance of histopathological examination in differential diagnosis of inflammatory diseases of the gastrointestinal tract.

Objective: To demonstrate the effectiveness of a supraciliary approach in zygomaticomaxillary complex fractures treatment.

Case report: Patient A. (33-year-old man) was admitted to the Scientific Research Institute – Ochapovsky Regional Clinical Hospital No. 1 (Krasnodar, Russian Federation) with a diagnosis of traumatic fractures of the right and left zygomaticomaxillary complexes. According to the medical history, the injury was caused by a car accident. The patient underwent computed tomography of the facial skeleton. Computed tomography findings: fractures of lateral and medial orbital walls, supraorbital and infraorbital rims, glabella, and nasal septum. The patient underwent repositioning of the bone fragments and internal fixation with metal implants. The glabella fracture was reduced through a supraciliary approach. The function of the mimic muscles was fully preserved. The configuration of the face and soft tissues was restored. No soft tissue edema was observed. The postoperative scar is visualized after the unfolding of the orbito-palpebral fold of the upper eyelid.

Conclusions: The systematic use of esthetic approaches by surgeons completely changes the rooted traditional way of managing patients with various maxillofacial pathologies. In addition to outstanding esthetic results, it increases the surgeons’ expertise level and the range of tasks a comprehensively developed specialist is capable of dealing with. One of the most crucial aspects is improvement of patients’ quality of life.

The existence of smartphones has brought both positive and negative impacts on human life. Unwise use of smartphones can lead to addiction, which affects communication. Establishing good relationships to prevent social alienation in interpersonal communication is important. This study aims to determine the relationship between smartphone addiction and the interpersonal communication skills of undergraduate nursing students and to determine the level of addiction and interpersonal communication skills at each level. The method used is correlational with a cross-sectional approach. The population consists of 464 undergraduate nursing students at the UPI Sumedang Campus with a sample of 215 students, using a stratified random sampling technique. This study uses a questionnaire instrument. Correlation data analysis uses Spearman's rank. The results of the study are that both variables are in the moderate category at each semester level, and the results of the correlation test with a p-value <0.001 (<0.005) have a significant relationship with a correlation coefficient of r -0.224, meaning the strength of the relationship is weak. The negative correlation value means that the higher the smartphone addiction, the lower the interpersonal communication skills. The conclusion of this study is that there is a relationship between smartphone addiction and the interpersonal communication skills of undergraduate nursing students. The level of addiction and interpersonal communication skills of all respondents were in the moderate category. It is recommended for students to use smartphones moderately and more wisely to avoid negative impacts.
