Authors: Palatkin P. P. , Konovalova N. G. , Zhatko O. V.
Published: September 2024

Introduction. This study is relevant due to the high prevalence of organic brain pathology and the negative influence of urination disorders on the quality of life.

Objective. To analyse the impaired function of lower urinary tracts in patients with organic brain pathology.

Materials & methods. We analysed 607 patients with severe organic brain pathology (105 had traumatic spinal cord injury (TSCI) and 457 had consequences of acute stroke (AS)). We performed clinical urological examinations. During the survey, attention was paid to the presence of urinary tract pathology at the examining time and anamnesis. Structural changes in the urinary tract were objectively assessed. We objectively assessed structural changes in urinary tracts including prostate adenoma in men, insufficiency of pelvic floor muscles in women and strictures of the urethra or ureters. The degree of the spastic syndrome was assessed with the Ashworth Scale. The neurourological examination included cystometry with the measurement of bladder volume and post-void residual urine. The cognitive status of the patients was assessed with the MMSE (Mini-Mental State Examination) questionnaire. The correlation analysis between the degree of spastic syndrome measured with the Ashworth Scale and urination disorders was performed with Spearman rank correlation.

Results. All patients had neurogenic dysfunction of the lower urinary tract. A combination of bladder retention and emptying disorders was found in 62 men older than 45yo with benign prostate hyperplasia (10,2% of all cases). An impaired accumulation function in history was found in 45 women older than 45yo (7,4% of all observations). The level of spasticity was 3 or 4 points on the Ashworth Scale in patients with TSCI and 2 to 4 points in those with AS. The analysis of correlations between the degree of spasticity and urination disorders showed a moderate relationship (r = 0,4) in patients with TSCI and a medium relationship (r = 0.65) in patients with AS.

Conclusion. Neurogenic dysfunction of the lower urinary tract accompanies patients with severe organic brain pathology throughout their life and requires adequate correction.

Published: September 2024

In recent decades, neural networks have been widely applied in many fields of science and medicine. Accurate and early diagnosis of malignancies is a key challenge in oncology. Neural networks can analyse a wide range of medical data and identify relationships between qualitative and quantitative features. This allows for more precise and timely diagnoses. Moreover, they can be used to predict tumour progression, evaluate treatment effectiveness, and optimise treatment plans for each patient

In oncourology, the use of neural networks offers new perspectives for the diagnosis, prognosis, and treatment of various cancer conditions related to the urinary tract and male reproductive system. This review article explores how neural networks are being used in this field and present research into the use of neural networks for diagnosing, predicting the course and treating urological oncological diseases. The advantages and limitations of using neural networks in this field are demonstrated, and possible directions for future research are suggested. The application of neural networks in oncourology opens new horizons for the development of a personalised approach to diagnosing and treating oncological diseases. Artificial intelligence has the potential to become a powerful tool for improving the accuracy of patient outcome predictions and reducing undesirable side effects of therapy. Introducing neural networks into oncourological practice creates new opportunities for enhancing the work of healthcare organisations and improving the quality of care provided to patients. This can lead to better treatment outcomes and improved patient satisfaction.

Published: September 2024

BACKGROUND

Anti-Asian hate crimes escalated during the COVID-19 pandemic; however, limited research has explored the association between social media sentiment and hate crimes toward Asian communities.

OBJECTIVE

This study aims to investigate the relationship between Twitter (rebranded as X) sentiment data and the occurrence of anti-Asian hate crimes in New York City from 2019 to 2022, a period encompassing both before and during COVID-19 pandemic conditions.

METHODS

We used a hate crime dataset from the New York City Police Department. This dataset included detailed information on the occurrence of anti-Asian hate crimes at the police precinct level from 2019 to 2022. We used Twitter’s application programming interface for Academic Research to collect a random 1% sample of publicly available Twitter data in New York State, including New York City, that included 1 or more of the selected Asian-related keywords and applied support vector machine to classify sentiment. We measured sentiment toward the Asian community using the rates of negative and positive sentiment expressed in tweets at the monthly level (N=48). We used negative binomial models to explore the associations between sentiment levels and the number of anti-Asian hate crimes in the same month. We further adjusted our models for confounders such as the unemployment rate and the emergence of the COVID-19 pandemic. As sensitivity analyses, we used distributed lag models to capture 1- to 2-month lag times.

RESULTS

A point increase of 1% in negative sentiment rate toward the Asian community in the same month was associated with a 24% increase (incidence rate ratio [IRR] 1.24; 95% CI 1.07-1.44; P=.005) in the number of anti-Asian hate crimes. The association was slightly attenuated after adjusting for unemployment and COVID-19 emergence (ie, after March 2020; P=.008). The positive sentiment toward Asian tweets with a 0-month lag was associated with a 12% decrease (IRR 0.88; 95% CI 0.79-0.97; P=.002) in expected anti-Asian hate crimes in the same month, but the relationship was no longer significant after adjusting for the unemployment rate and the emergence of COVID-19 pandemic (P=.11).

CONCLUSIONS

A higher negative sentiment level was associated with more hate crimes specifically targeting the Asian community in the same month. The findings highlight the importance of monitoring public sentiment to predict and potentially mitigate hate crimes against Asian individuals.

Authors: Si Yafei , Yang Yuyi , Wang Xi , Zu Jiaqi , Chen Xi , Fan Xiaojing , An Ruopeng , Gong Sen
Published: September 2024

UNSTRUCTURED

Using simulated patients to mimic 9 established noncommunicable and infectious diseases, we assessed ChatGPT’s performance in treatment recommendations for common diseases in low- and middle-income countries. ChatGPT had a high level of accuracy in both correct diagnoses (20/27, 74%) and medication prescriptions (22/27, 82%) but a concerning level of unnecessary or harmful medications (23/27, 85%) even with correct diagnoses. ChatGPT performed better in managing noncommunicable diseases than infectious ones. These results highlight the need for cautious AI integration in health care systems to ensure quality and safety.

Authors: Heizmann Anne-Noëlle , Ollier Edouard , Labeix Pierre , Goujon Ivan , Roche Frédéric , Le Hello Claire
Published: September 2024

BACKGROUND

Smartwatches are increasingly used to monitor and motivate physical activity. Cardiovascular disease patients and peripheral artery disease patients often do not meet national physical activity recommendations. They may, thus, benefit from a physical activity program using smartwatches. The Life Plus smartwatch is designed to facilitate activity monitoring by counting steps, but its validity needs to be determined, particularly in patients who may not have a normal gait, such as those with cardiovascular pathology.

OBJECTIVE

This study evaluates the accuracy of the Life Plus smartwatch (versions 2 and 3) in healthy subjects, cardiovascular disease patients and peripheral artery disease patients at different walking speeds (1.8, 2.5, 3.2, and 4 km/h) and different localizations (wrists, hips and ankles) to determine best accuracy.

METHODS

Thirty-four participants, comprising of healthy individuals (n=10), patients with cardiovascular disease (CVD) (n=14), and patients with peripheral artery disease (PAD) (n=10), wore 6 Life Plus watches simultaneously (3 of version 2 (V2) and 3 of version 3 (V3)), located on wrists, hips and ankles. Participants walked on a treadmill for 3-minutes sessions at speeds of 1.8, 2.5, 3.2, and 4 km/h, they then performed a 10-minute free walking on the ground and again 3-minutes walking sessions on treadmill at the same speeds. Actual step counts were recorded through video footage.

RESULTS

When worn at the wrist, no significant difference between actual number of steps and step count by V2 watches were found in each group independently (healthy group: P=.25; CVD group: P=.50; PAD group: P=.37). Significant differences were found with the V2 watches at the wrist in healthy group at 3.2 (-5.26%) and 4km/h (-6/13%) (P<.05); in CVD group at 2.5 (-5.94%), 3.2(-13.1%) and 4 km/h (-13.96) (P>.05). When worn at the wrist, no significant difference between actual number of steps and step count by V3 watches were found in the healthy group and the PAD group (healthy group: P=.02); PAD group: P=.90). Significant differences were found with the V2 watches at the wrist in CVD group at 3.2 (-6.43%) and 4 km/h (-7.3%) (P>.05) and in PAD group at 4 km/h (-5.77%) (P<.05).

CONCLUSIONS

For optimized counting when worn at the wrist, healthy individuals should prefer V2 watches for slow walking (1.8 and 2.5 km/h) and V3 for higher speeds (3.2 and 4 km/h). Patients (CVD and PAD) should prefer V2 watches at 1.8 km/h and V3 watches for higher speeds (2.5, 3.2 and 4 km/h).

CLINICALTRIAL

This study was not registered in clinical trials but was approved by the ethics committee of the University Hospital of Saint-Etienne in June 2022 (reference CE 2022-36).
Stakeholders and contextual factors in the implementation of an assistive robot arm for persons with tetraplegia: a deductive content analysis of focus group interviews (Preprint)
Authors: Fosbrooke Vera , Riguzzi Marco , Raab Anja Maria
Published: September 2024

BACKGROUND

Tetraplegia imposes significant challenges on individuals, caregivers, and healthcare systems. Assistive technologies (AT) like assistive robot arms have shown to improve the quality of life of persons with tetraplegia, fostering independence in daily activities and reducing caregiver burden. Despite potential benefits, the integration of AT innovations into daily life remains difficult. Implementation science offers a systematic approach to bridge this know-do gap.

OBJECTIVE

The objective of this review was to (1) identify and involve relevant stakeholders, (2) identify relevant contextual factors (barriers and facilitators), and (3) suggest a general outlook for the implementation of AT, specifically an assistive robot arm, within the everyday private life for persons with tetraplegia in Switzerland.

METHODS

A qualitative design, involving three semi-structured online focus group interviews with eight stakeholder groups (affected person, engineering/technology, legal perspective, nursing/care, therapy, social counselling, social insurers, political perspective), was used. The interviews were analysed using the Focus Group Illustration Mapping (by Pelz et al. (2004)), and data aligned with the domains of the Consolidated Framework for Implementation Research (CFIR).

RESULTS

Three focus group interviews, comprising 22 participants, were conducted and data was mapped onto 21 constructs of CFIR domains. Identified barriers were the customisation to the users’ needs, safety concerns and financing issues of high AT costs. The collaboration with different stakeholders including political engagement proved crucial. Identified facilitators included the enhancement of autonomy for persons with tetraplegia, improvement of quality of life, reduction of caregiver dependency, and addressing healthcare labour shortages. The implementation outlook involved the formation of an experienced team, and the development of an implementation plan using Hybrid Type 1 and Type 2 designs incorporating qualitative and quantitative implementation and innovation outcomes.

CONCLUSIONS

The robot arm offers promising benefits in terms of improved participation for the users, while high costs and regulatory complexities for the assumption of costs limit its implementation. These findings highlight the complexities involved in implementing AT innovations and the importance of addressing contextual factors. A specific framework for the implementation of AT is needed to ensure the successful integration into the Swiss and comparable social and health insurance systems.

Published: September 2024

BACKGROUND

Accessibility barriers contribute to low participation in center-based cardiac rehabilitation. We developed an innovative, comprehensive, dual-phase telerehabilitation program to address this gap (Smartphone Cardiac Rehabilitation Assisted Self-Management; SCRAM).

OBJECTIVE

To determine the effectiveness of SCRAM for increasing maximal aerobic exercise capacity (VO2max).

METHODS

A multi-center, parallel two-arm randomized controlled trial recruited clinically stable adults (aged 18+ years) with diagnosed coronary heart disease at three hospitals in Victoria, Australia (Melbourne, Geelong, Bendigo) from 2018-2021. Participants were randomized (1:1), stratified by sex and study site, to receive SCRAM plus usual cardiovascular care (intervention), or usual cardiovascular care alone (control). SCRAM intervention provided 24 weeks of remote exercise supervision, coaching, and behavior change support via smartphone. Usual cardiovascular care included standard medical care and advice to seek a referral to centre-based cardiac rehabilitation (CR), which was heavily impacted during the COVID-19 pandemic. Due to the nature of the treatments, participants were not blinded to allocation; primary outcome assessors and biostatisticians were blinded. The primary outcome was VO2max at 24 weeks, analyzed on the principle of intention-to-treat, using linear regression adjusted for baseline and stratification factors on multiple imputed data.

RESULTS

Recruitment and data collection were heavily impacted by COVID-19, although SCRAM delivery was sustained throughout. Of 220 required participants, only 123 (56%) were recruited and randomized (intervention n=63, control n=60); 45% had missing VO2max at 24 weeks—largely due to enforced COVID-19 restrictions. VO2max at 24 weeks favored SCRAM, but this was not statistically significant (mean difference=1.61 ml/kg/min; 95% CI [-1.38, 4.61], P=.28). Among secondary outcomes, patients receiving SCRAM had lower diastolic blood pressure at 24 weeks (mean difference=-5.54 mmHg; 95% CI [-10.01, -1.06]).

CONCLUSIONS

SCRAM was resilient to COVID-19-related disruptions to CR delivery but, while findings were inconclusive, it did not lead to a clinically important difference in VO2max. Further research is needed to conclusively assess treatment effects and understand how virtual CR delivery models can be translated into routine practice.

Published: September 2024

Utmost tropical nations regard the sweet potato( Ipomoea batatas(L.) Lam.) as their most significant chief crop. It's substantially privileged for its capability to deter disaster, improvement, and produce with many inputs. A study was carried out during the 2020 and 2021 growing time seasons in a field trial conducted at the University of Ebonyi State – CAS , to determine variability among sweet potato accessions, and identify traits that are positively and significantly associated with yield and accessions with high yield. A randomized complete block design with three replications was used to determine variability among sweet potato accessions, The results of both years combined statistical analysis indicated that the types significantly varied in terms of all yield and yield- related traits. As a result, the Umu SPO 3 acquired had the topmost values of average root storage in both the 2020 (5.2 cm) and 2021 (2.4 cm) growing seasons. In both 2020 and 2021 growing seasons and over time combined analysis, the haughtiest average root yield (2.67 Kg), and total root yield(8.89 t/ ha) were recorded for Koudakou. PCV was advanced than GCV suggesting a major environmental influence on those characters. Low heritability coupled with high, moderate, and low inheritable advance in percent of mean was observed in all characters. Traits considered in the study revealed positive and significant correlations. The grouping of accessions into two main clusters highlights genetic relationships among them. Understanding these relationships can help breeders identify potential parent lines for cross-breeding, which can lead to the development of new varieties with desirable traits.
The Teaching of Reading to English Majors in China (1950-2020): Historical Development, Current Predicament and Potential Solutions
Authors: Liu Shuyan , Sun Haiying
Published: September 2024

This paper examines the historical development, current predicament, and potential solutions pertaining to the teaching of reading to English majors in China, with a specific focus on the course commonly known as "Intensive Reading" or "Comprehensive English". It investigates its evolution over a span of more than seventy years. It reveals that the educational objective for English majors has increasingly emphasized the development of language proficiency and humanistic literacy. The positioning of the course, however, has largely remained as a comprehensive language-skills training course, lacking clear objectives and effective operational norms. To better align with current educational goals, this paper proposes the course positioning as an enlightening and inspiring course that promotes language proficiency, enhances humanistic literacy, and establishes connections with disciplinary knowledge. It also sets the objectives as providing perspectives from literature, linguistics and related disciplines, and guidance on learning methods, aiming to guide students in exploring and studying texts to achieve a profound understanding in both language and ideas. Based on an analysis of the challenges associated with the traditional practice, content-based instruction and production-oriented approaches, this paper proposes potential solutions that involve integrating autonomous learning with in-class instruction and incorporating disciplinary knowledge into language learning.

Published: September 2024

Arabica coffee supplies 60% of world coffee production because has a unique taste as superior quality beverage. Arabica coffee micropropagation can be conducted by somatic embryogenesis technique which produce clonal, fast dan uniform plant. The somatic embryogenesis (SE) process describes the integration of endogenous signals and gene reprogramming, which releases signals to initiate embryogenic processes. The use of endogenous auxin, either alone or in combination with other PGRs or stress, induces differential gene expression, which modifies the genetic program of somatic cells and regulates the transition to each stage during SE development. The RKD4 gene (RWP-RK DOMAIN-4) is a gene that plays a role in early initiation embryo formation and development. The characterization of RKD4 genes in C. arabica is still limited and under explored. The objective of this research is to explore the characteristics of RKD4 gene by comparing the difference and similarity of RKD4 gene in C. arabica and other cultivated plants. The method was initiate by identifying nucleotide sequences from the National Center for Biotechnology Information (NCBI) database. Furthermore, consists of analysis of nucletide alignment, alignment of amino acid sequences, protein analysis, protein motif functions discovery, analysis of phylogenetic tree, protein 2D and 3D-modelling and physiochemical properties. According to the analysis, there were 100 polymorphism points with a total number of mutations of 211 points. The phylogenetic tree show C. arabica L. has a very close relationship with grapes (Vitis vinivera) based on the RKD4 protein, gene structures and protein motifs. There are nine highly conserved motifs found in the protein alignment. C. arabica L. had more methyl jasmonate element responses than A. thaliana. The findings are useful to understand the intitiation of embryo formation mechanisms of C. arabica L and other cultivate plants during propagation through somatic embryogenesis in the long run.

Mathematical connection ability is an important factor in understanding mathematical concepts. The aim of this research is to analyze the level of students’ mathematical connection abilities and junior high school students’ self-confidence. The method used in this research is a descriptive-qualitative method. The research subjects were 37 students in class VIII-C of SMPN 3 Margahayu. The instruments used were four items of mathematical connection test material on the System of Two-Variable Linear Equations and non-tests of students’ confidence in learning mathematics. The results of the analysis show that the average score of all mathematical connection ability test questions in indicator 1 using relationships between mathematical topics is 5%, indicator 2 is understanding equivalent representations of the same concept (36%), indicator 3 uses mathematics in everyday life (52%), and indicator 4 uses mathematics in other subjects (27%). So the average is 30%. So the students’ mathematical connection ability is included in the low category. Most students are unable to solve problems with indicators using relationships between mathematical topics. This is shown by the results of the mathematical connection ability test; students did not connect optimally. But in learning mathematics, students already have good self-confidence.
Mandume e outras histórias: discursos contra-coloniais em Chimamanda e Emicida
Authors: Nascimento Roberta Teixeira
Published: September 2024

A partir do que Chimamanda Ngozi Adichie apresenta em O perigo de uma história única, uma importante contribuição da autora para romper com as amarras coloniais, pretende-se neste artigo elaborar uma reflexão entrecruzada com materiais sobre a canção Mandume, composta pelo rapper Emicida. Dessa forma, ao se considerar uma perspectiva contra-colonial, é possível refletir sobre a música Mandume que traz em seu nome um líder e uma história pouco conhecidos, ajudando a pensar a respeito do rap como uma expressão musical que tem contado outras histórias e rompido com a história hegemônica/colonial. Durante o artigo, fragmentos da letra da música Mandume são analisados, demonstrando conter um potente discurso contra-colonial, característica presente também em outras produções do rapper brasileiro Emicida.
Adding to the Narrative: Intersectional Feminist Critical Curatorial Practices in Classical Vocal Music Performance
Authors: Shanice Skinner
Published: September 2024

Diversity and inclusion within Western art music have become topics of elevated importance in in recent discussions. To create enduring results regarding these matters, there needs to be a commitment to in-depth study of practices that will produce visible change. This is one of the goals of my research, in which I tackle issues of representation by focusing on Black women composers and their absence from the canon as overlooked and marginalized artists. It is well known that women have been denied many opportunities throughout history; as composers, many experiences crucial to professionalism were not always available to women, including music education in composition, the publication and circulation of their works, not being hired as conductors, or receiving reviews from influential critics. These opportunities and resources dwindled further if a woman was also a person of colour. Thus, in order to ensure their inclusion within the canon, these underrepresented identities demand and require unique recognition.

I have examined the issue of neglected women of colour composers in classical music from an interdisciplinary standpoint, utilizing the methodologies of history and experimentation to form an “intersectional feminist critical curation” framework. This framework implements knowledge from intersectional feminist theory and music curation practices in order to answer following questions: “What is the impact on new audiences of diverse backgrounds experiencing classical music through an intersectional feminist curatorial framework?”, "Can classical music be an effective device for messages of social and political change?", and “What is the impact on myself as a classical vocalist and a Black woman to implement an intersectional feminist curatorial framework within my musical study and performance?”. The overall goal of this research was to discover an effective way forward to achieving diversity in classical music for underrepresented groups. Drawing from this study, I have created a digital performance project entitled “The Narrativity Sessions,” which functioned as an experiment utilizing this knowledge of intersectional feminist theory and praxis fused with select critical curation strategies applied to my own artistic practice as a classical singer. The outcome was a novel artistic practice that can contribute to creating innovative and artistically fulfilling performances while simultaneously advancing diversity and inclusion in the classical music sphere for audiences, performers, and composers alike.
Walton viola Concerto beyond the score
Authors: Alberto García Pérez
Published: September 2024

The Walton Viola Concerto is one of the most famous and recognized compositions in the viola repertoire. Apart from this, it is a compulsory piece in any viola orchestra audition. This research is focused on my practice and artistic process of the Walton Concerto, consequently subjective, to create an artistic choice. In order to achieve an ideal interpretation of this composition, I will investigate and analyze the first two recordings made of the Concerto, as both represent different versions of the piece with several differences between them. These recordings were made by Frederick Riddle in 1937, and by the famous violist William Primrose in 1946. This research aims to: (1) decide what details or alternatives I can recover from these recordings to inspire my own interpretation, and (2) find out what ideas from the first recording are reflected in the second one. Taking into consideration these recordings, I first drew up a list mentioning the differences found between them. Then, I classified these differences into different categories such as bowings, different notes, fingerings, orchestration, and so on. Finally, I recorded myself playing both versions of some passages. The main outcome I found is to discover that the sound-based approach (listening to recordings and experimenting with them) is a richer source of inspiration for a musician than a purely score-based comparison. I hope these artistic ideas can be a great stimulus and encouragement to other violists who want to play this wonderful Concerto.
Holding the violin and how it influences sound and playing in historical performance practice. Historical perspectives.
Authors: Agnieszka Papierska
Published: September 2024

Name: Agnieszka Papierska
Main subject: Baroque violin
Title of research: Holding the violin and how it influences sound and playing in historical performance practice. Historical perspectives.
Research coach: Margaret Urquhart

Research questions: How much would the sound of the violin change with holding it in different position? Could this be a tool of expression? Does the way we hold the instrument influence other choices we make about performance practice e.g. regarding fingering, bowing? Could this knowledge be used in performance practice today?

Summary of results:
During the baroque and classical period many different ways of holding the violin existed, often at the same time. This paper investigates the way in which the different positions of holding the instrument could change the sound of it. After studying at sources and making experiments with different posture it can be confirmed that that the sound changes with different ways of holding the violin. The technique and interpretation are also affected. The main conclusion is that violin technique is not unchangeable. We can adjust it in order to develop sound that we desire.

Constructing a framework for interdisciplinary performances featuring classically trained musicians and dancers or actors
Authors: Joel Gester Suarez
Published: September 2024

The research aims to construct a framework for interdisciplinary performances. This framework is organised in the different components that shape creative processes. The research follows a process that begins with my experience in the dance-music collaboration “The Devil on the Dance Floor”, which included my ensemble Quinteto del Diablo, dancer Rosanna Ter Steege, and stage director Laura Suárez. The insights gained from this project, as well as the interview with director and actress Laura Suárez, led to the theorisation of the framework.
The mentioned components are organised in a map. Each one of them serves as a possible starting point for a creative process. The propositions drawn from the framework support the notion of non-hierarchical creative processes. However, it also concludes that all the mentioned components have to be observed and worked with according to their qualities. After the layout of the framework, the interview with dancer and choreographer Mar López provides a critical comparison to support the theory through the experience of someone outside my environment. The last section analyses my master project, a piano-dance duo with Rosanna ter Steege, as a practical application of this theoretical framework. The research aims to set a framework that can help me and others, especially classically trained musicians, when working on an interdisciplinary performance. The format of the presentation is a research exposition.
