The art of asking and presence: Authentic pastoral hospitality
Authors: Botha Annelie
Published: October 2024

Health and being healthy is the source of strength for life. Being healthy is more than just the absence of physical illness. Being healthy includes mental, social and spiritual well-being. The task of pastoral care and counselling includes meeting people in the spaces and places where they struggle to cope with the adversities that are part of life and make it difficult for them to live a healthy and whole life. Such pastoral care will include addressing lifestyle issues and environmental factors that affect people’s health and well-being in the broadest sense.
How religious communities can assist in addressing the needs of sick and hospitalised children
Authors: Oberholzer Annemarie E.
Published: October 2024

A visitor from the church came to see the six-year-old in the children’s intensive care unit, and I gave them some space. It was an open-plan unit, and from where I was standing at the nurse’s station, there was an unobstructed view of the scared little face of the child. The visitor was praying, but, as seen so many times in a paediatric unit, the wording of the prayer was aimed at the adults around the bed, causing nothing more than confusion and misconceptions in the mind of the child.
Social media is in young people’s nature: Environmental sustainability, awareness, consciousness and activism during the Fourth Industrial Revolution era
Authors: Beukes Jacques
Published: October 2024

The Fourth Industrial Revolution (4IR) can be defined as an integration of technologies that obscures the boundaries between the physical or real, biological and digital, domains, collectively known as cyber-physical systems. Furthermore, as a result of the COVID-19 epidemic, several elements of the 4IR have been expedited, with social media and digital platforms being examples. Although there is growing recognition that the 4IR has the potential to worsen issues for people and the earth, it also has the ability to alter and realign societies. Several youth movements have emerged to address the environmental and climate change problem. The youth population is a focal point in the discourse surrounding ecological justice, environmental awareness, and initiatives related to climate change. Youth movements throughout the world, such as ‘Extinction Rebellion’ and ‘Fridays for Future’ show that young people are concerned about environmental issues and want to get involved in climate change activism. Their desire to act on their own behalf makes them one of the most essential and fascinating groups to learn more about when it comes to the problem of increasing environmental knowledge, consciousness, and action.

Mission studies: The inevitable for theological studies
Authors: Knoetze Hannes
Published: October 2024

When writing about missiology/mission studies within the African context, it is important to take cognisance of the fact that when Christian mission came to Africa at the beginning of the fifteenth century, ‘there was no developed theology of mission’ (Oborji, 2020:6). Currently, we are writing and studying mission and missiology mainly from a post-Christendom perspective in the West, and in the global world with a mixed (syncretistic) perspective of traditional beliefs, Christendom, and post-Christendom societies. But mission is from everywhere to everywhere.
Facebook Communication by South Africa’s Eight Metros
Authors: Kaunda Lakela , Mukonza Ricky
Published: October 2024

The dawn of social media has changed the way people work, live and play, given the proliferation of digital communication tools at their fingertips. It has also added new platforms to the instruments that government and the public can use to communicate. Using the development communication approach as a theoretical framework, this chapter explores how the eight South African metropolitan municipalities use social media – particularly the Facebook platform – to engage in two-way communication with the public. Local government was selected for study as it is regarded as the sphere that is closest to the people (Mkhize, 2018). The delivery of basic services such as as electricity, access to potable water, proper sanitation and waste removal, street lighting, cutting the grass on the verges of the roads, repairing potholes and ensuring correct billing systems for both households and businesses, are delivered by municipalities (Madumo, 2015; Mkhize, 2018).
Influencing Voter Turnout: Analysing the IEC’s Stakeholder Communication Strategy in the 2021 Local Government Elections
Authors: Sitto-Kaunda Karabo
Published: October 2024

The Independent Electoral Commission is a Chapter 9 institution tasked with all responsibilities related to voter education and communication in South Africa and is thus a key public institution. The right to vote is protected by the institution, given South Africa’s political past, which politically excluded a significant majority of the population. The decreasing voter turnout is therefore of great public concern, with record lows in the numbers of voters casting their ballots for the local government elections of 2021. These local government elections were contentious for numerous reasons, including the limitations on electioneering due to COVID-19 regulations (Mokoena, 2021).
Public Sector Communications and Institutionalised Bureaucracy
Authors: Dingalo Margaret L.
Published: October 2024

In democratic societies, the right to access information is critical for public participation processes. Transparency, accountability and trust are closely associated with how public institutions openly and honestly engage communities on decisions that affect their lives (Hyland-Wood, Gardner, Leask & Ecker, 2021). The role that public sector communicators play in enabling participation and enables citizens to judge the work of public institutions (Canel & Sanders, 2012). Public sector communicators are tasked with facilitating communications between the public institutions and the citizens they serve (Ruijer, 2013). Communicators that work in public institutions make a valuable contribution in facilitating transparency, participation and engagement in policy-making processes, according to the Government Communications and Information Service of South Africa (GCIS, 2019).

Published: October 2024

O futsal feminino é uma modalidade que vem expandindo no Brasil como prática esportiva e competição. Nos últimos anos ocorreu maior investimento na modalidade o que torna a prática do esporte mais competitiva, exigindo mais preparo físico, consciência corporal e conhecimento adequado da técnica. Sendo assim, o objetivo do presente estudo foi verificar se existe correlação entre o desempenho nos testes de saltos verticais e a pontuação total da bateria de teste Functional Movement Systems (FMS) em jogadoras de futsal. As participantes foram jogadoras de futsal da equipe da Faculdade SOGIPA do sexo feminino. A amostra foi selecionada por conveniência e composta por 13 jogadoras. A idade média das participantes foi de 20,20 ± 4,76 anos. Foi aplicado o teste de avaliação funcional do movimento pela bateria de teste FMS para identificar os padrões de movimento das jogadoras de futsal e foi mensurada a altura nos saltos squat jump e countermovement jump (CMJ) pelo aplicativo My Jump 2 (Apple Inc. USA). O coeficiente de correlação de Spearman foi usado para determinar a relação entre os testes do FMS e saltos. Os resultados do presente estudo indicaram que a pontuação total do teste FMS possui correlação grande, positiva e significativa apenas com a altura no CMJ (ρ = 0,605, p = 0,029). Conclui-se que existe correlação entre a pontuação total do FMS e a altura no CMJ. Assim, sugerimos que uma melhor qualidade funcional do movimento pode estar associada a melhora do desempenho físico em jogadoras de futsal e isso deve ser considerado na preparação física das jogadoras.DOI: 10.36692/v14n3-14

Introdução: O retinoblastoma é uma patologia maligna ocular que se origina nas células da retina, a camada sensível à luz que reveste o fundo do olho. Se não for diagnosticado e tratado a tempo, o retinoblastoma pode levar à morte ou à perda da visão, pois o tumor pode crescer e invadir outras partes do globo ocular e do corpo. Apesar de, a causa exata do retinoblastoma seja desconhecida, alguns estudos sugerem que há uma ligeira tendência de ocorrer mais em meninos do que em meninas, mas essa diferença não é significativa nem influencia as características clínicas da doença. Objetiva-se, analisar e descrever a neoplasia retinoblastoma e seus aspectos genéticos, diagnósticos e terapêuticos. Metodologia: Refere-se a uma revisão da literatura, onde as buscas ocorreram nos bancos de dados: Biblioteca Virtual de Saúde e Scielo, artigos no período de 2017 a 2024. Resultados e Discussão: Nas buscas sobrevieram 10 artigos elegíveis para a amostra final do estudo. O retinoblastoma é um câncer que se forma na retina, a camada de células sensíveis à luz que reveste o fundo do olho. A causa principal é a mutação no gene RB1, que controla o crescimento celular. O diagnóstico é feito pelo teste do olhinho, que verifica o reflexo vermelho na pupila, ou por exames de imagem, que mostram as calcificações no tumor. A biópsia é contraindicada, pois pode espalhar o câncer, o tratamento é complexo e envolve uma equipe multidisciplinar de especialistas. O SUS oferece atendimento gratuito e integral aos casos de retinoblastoma, além disso, o diagnóstico precoce é essencial para o sucesso do tratamento e a prevenção da cegueira infantil. Considerações finais: Para melhorar o prognóstico e a qualidade de vida dos pacientes com retinoblastoma, são necessárias ações que visem aprimorar o diagnóstico precoce, a preservação da visão, a educação em saúde, o apoio psicossocial e a divulgação dos sinais e sintomas da doença, bem como dos avanços científicos e tecnológicos na área. A conscientização e a mobilização da sociedade são fundamentais para combater esse tipo de câncer ocular infantil.

CLIMATE CHANGE FORECASTING USING DEEP LEARNING
Authors: Hari Babu Guraka
Published: October 2024

Climate change is defined as a long-lasting change in the mean weather patterns found on Earth. These changes are either natural, or human made. Since the 19th century, climate change has been on the rise. This is mostly due to igniting fossil fuels like gas, coal, and oil. These can lead to various problems like food and water scarcity, disease, increased flooding, extreme heat, and economic loss. It can also cause the sea levels to rise, and make oceans warmer and more acidic, and escalate human migration. It is referred to as the most significant threat to health on a global scale by the World Health Organization. Even if the efforts made to reduce future warming is successful, some effects will continue for tens of decades.
This paper attempts to forecast climate change based on the changes in temperature across the globe from the 19th century onwards. A deep learning-based time series model is built using Recurrent Neural Networks (RNNs) to forecast the average temperature. This model will attempt to predict future values based on historical data.

BLOCKCHAIN-BASED FEDERATED LEARNING WITH SMPC MODEL VERIFICATION AGAINST POISONING ATTACK FOR HEALTHCARE SYSTEMS
Authors: DR. B.SARADA  , VARSHA PATLOLLA , SINDHU NALLURI , UMA MEDURI
Published: October 2024

Due to the rising awareness of privacy and security in machine learning applications, federated learning (FL) has received widespread attention and applied to several areas, e.g., intelligence healthcare systems, IoT-based industries, and smart cities. FL enables clients to train a global model collaboratively without accessing their local training data. However, the current FL schemes are vulnerable to adversarial attacks. Its architecture makes detecting and defending against malicious model updates difficult. In addition, most recent studies to detect FL from malicious updates while maintaining the model’s privacy have not been sufficiently explored. This paper proposed blockchain based federated learning with SMPC model verification against poisoning attacks for healthcare systems. First, we check the machine learning model from the FL participants through an encrypted inference process and remove the compromised model. Once the participants’ local models have been verified, the models are sent to the blockchain node to be securely aggregated. We conducted several experiments with different medical datasets to evaluate our proposed framework.

Published: October 2024

This study presents an innovative approach to classifying Diabetic Retinopathy Disease (DRD) levels through the application of Graph Neural Networks (GNNs). By transforming retinal images into graph representations and extracting topological features, the proposed method aims to enhance the precision of DRD classification. GNNs are employed to leverage complex relationships within graph-structured data, offering a more nuanced understanding of retinal structures and disease progression. The results demonstrate that this approach significantly improves classification accuracy compared to traditional methods, providing valuable insights for early diagnosis and personalized treatment strategies. This advancement promises to contribute to more effective management of diabetic retinopathy and improved patient outcomes.

Des techniques avancées efficaces pour améliorer le traitement des rejets de stations d’épuration ont été développées pour répondre à la demande croissante de protection des ressources en eaux et aux menaces pour la sécurité de l’eau liées aux contaminants (chimiques, biologiques) provenant des rejets. Récemment, l’utilisation de l’acide performique (PFA) suscite un intérêt croissant grâce à ses propriétés oxydantes élevées. La plupart des travaux de recherche se sont concentrés sur son efficacité à éliminer les
bactéries indicatrices fécales qui sont utilisées pour contrôler la qualité biologique des rejets. Mais les effets potentiels des rejets traités à l’acide performique sur les communautés microbiennes du milieu récepteur restent moins renseignés. Dans ce travail, les effets potentiels de rejets de stations d’épuration traités au PFA sur les
micro-organismes du milieu récepteur, dans le cas présent la Seine, ont été étudiés. Pour cela, des expériences en laboratoire ont été mises en place. Le rejet de la station de Seine Centre traité au PFA à 2 mg/L pendant 10 min a été mis en contact avec l’eau de la Seine pendant 60 min. L’abondance, les activités et la diversité des communautés microbiennes de ce mélange ont été suivies à pas de temps réguliers durant 60 min. Les résultats montrent que dans les conditions expérimentales de cette étude, il subsiste un effet rémanent léger après la mise en contact des rejets traités au PFA avec de l’eau de la Seine. L’activité et la diversité microbienne des eaux de la Seine recevant les rejets non traités diffèrent également légèrement de celles des eaux de Seine recevant rejets traités au PFA pour les 15 premières minutes. Cela est probablement dû à la différence de concentration des cellules microbiennes intactes/endommagées dans les rejets traités ou non. Cette différence pourrait affecter la capacité de dégradation de la matière organique durant ces 15 premières minutes, tout comme la présence potentielle de PFA résiduel. Dans l’ensemble, nous n’avons pas observé d’impacts spécifiques des rejets traités au PFA sur les micro-organismes de la Seine. D’autres expériences et mesures sont nécessaires pour confirmer les effets mineurs observés au début du contact. Les résultats de cette étude apportent un premier retour d’expérience dans des conditions d’exploitation sur la désinfection au PFA, soulignant l’impact réduit des rejets traités au PFA sur les communautés microbiennes du milieu récepteur.
Applications of radionuclide-carrying liposomes for diagnosis and treatment of cancer
Authors: Basu Rashmi , G. Schwartz Joyce , T. Phillips William
Published: October 2024

Using nanocapsules to deliver diagnostic and therapeutic agents to targeted biological sites enhances the safety and effectiveness of healthcare by decreasing toxicity and increasing the accumulation of medicinal agents at targeted sites. Liposomes, nanocapsules made of naturally occurring lipids, boast many advantages for the delivery of therapeutic agents. This article reviews both the advantages and challenges associated with liposomal drug delivery for the treatment of cancerous tumors and infectious diseases. These minute spherical sacs of phospholipid molecules are flexible carriers that can be modified in various ways to optimize their use. Examples of this include alteration of the size of liposomes to selectively accumulate in tumor microenvironments and “PEGylation” of their surface to reduce uptake of liposomes by the mononuclear phagocytic system (MPS). While one of the main challenges of liposomal drug delivery is the heightened uptake of liposomes by the MPS, this unique property can be used to target diseased areas with a significant MPS presence. Furthermore, the liposomal structure can be manipulated to allow for the triggered release of internal contents with externally controlled factors. Liposomes carrying therapeutic radionuclides can be injected directly into solid tumors and dispersed throughout the tumor by convection-enhanced delivery. The flexibility and pliability of liposomes allow them to move through tight spaces within a tumor with much greater dispersion and penetration when compared to more rigid nanoparticles. Due to the benefits of radionuclide-carrying liposomes in disease diagnosis and delivery of chemotherapeutic agents, their utilization is expected to be expanded.

Published: October 2024

Methacrylic anhydride-based hydrogels, derived by introducing methacryloyl groups to various polymer side chains, are promising bioinks for 3D printing in medical applications. These hydrogels combine the inherent biocompatibility and therapeutic benefits of their parent polymers with the unique photocrosslinking properties conferred by the methacryloyl groups, allowing the precise control over their mechanical properties through light-curing parameters. Using three-dimensional (3D) biological compression, these hydrogels serve as bioinks for producing scaffolds with optimal porosity, facilitating cell adhesion, proliferation, and differentiation. This technology enables the precise spatial distribution of bioactive substances, offering targeted therapeutic treatment and controlled release. This review delved into recent advancements in bioprinting technologies, outlined the preparation of methacrylic anhydride-based bioinks, and summarized factors influencing the resulting biological and mechanical properties of bioscaffolds. Additionally, the properties and applications of methylpropionic anhydride-based hydrogels in various medical fields were discussed, addressing current limitations and future challenges in integrating these hydrogels with 3D bioprinting for clinical applications.
Effectiveness of cognitive interventions in mitigating mental fatigue among healthcare professionals in hospital settings: A systematic review
Authors: Gonçalves Sara , S. Matos Rita
Published: October 2024

Mental fatigue poses a significant challenge to healthcare professionals in hospital settings, impairing cognitive performance, emotional well-being, and job satisfaction. This systematic review evaluates the effectiveness of cognitive interventions, including mindfulness programs, online psychological interventions, and telehealth cognitive-behavioral therapy (CBT), in mitigating mental fatigue among healthcare workers. A comprehensive literature search across PubMed, b-on, Web of Science, and Scopus identified six studies published between 2016 and 2023. These studies reported that cognitive interventions significantly reduced burnout and stress levels, with up to a 30% decrease in emotional exhaustion and improved coping mechanisms. In addition, participants demonstrated enhanced emotional well-being, reflected in increased mindfulness and life satisfaction scores of as much as 25%. Mindfulness-based programs and telehealth CBT were particularly effective in fostering resilience and improving overall cognitive function. However, the review also highlighted the need for future research to explore the long-term effects of these interventions, their cost-effectiveness, and innovative methods to improve accessibility and scalability, such as digital platforms. Integrating cognitive interventions into routine healthcare practice can enhance staff well-being, improve patient outcomes, and contribute to a more supportive work environment.

Authors: Mavrogiannis Theo
Published: October 2024

Abstract: Nea Paphos-seat of the strategos during the Ptolemaic era and of the proconsul after its annexation to the dominions of Rome-remains basically a Hellenistic city until late imperial times. Although numerous archaeological missions are devoted to the activity, one of the aspects still to be clarified remains that of the gymnasium and its relationship to the agora. Through the analysis of inscriptions and comparisons with other known monuments of the Ptolemaic reign, an attempt will be made to shed light on this aspect. It will contribute to the location of the building and its relationship to the agora.

Smaller or Smallest? Investigating the Optimal Small Group Size in Online Forums
Authors: Yang Tianxiao , Lei Jing , Niu Zhijuan
Published: October 2024

Previous studies have confirmed the benefits of small group sizes in asynchronous online discussions. However, there is no consistency in which small group size is the optimal option for maximizing students’ discussion performance. Moreover, few researchers attempted to apply the smallest group size (i.e., one-on-one) to online discussions and examined its effects. This study focuses on comparing two small group size choices regarding students’ discussion performances. 21 graduate students formed pairs in the first half of the semester, and in the second half, they formed groups of three to five. Paired-sample t tests were conducted to detect the performance differences between the two group sizes. The results showed that students significantly performed better in contributing interactions, providing information, engaging in social conversations, demonstrating cognitive engagement, and constructing knowledge. This study provided a new perspective of designing discussion activities in online forums.

This system is applicable in diverse modern technologies, in particular in call centers. We establish the steady-state solution as well as important system characteristics by means of probability generating functions technique. We also construct the expected total cost for this model and develop a procedure to determine the optimal service rate that yields the minimum cost. Further, we carried out a comparative analysis to obtain the minimum cost using the Newton–Raphson method and particle swarm optimization (PSO) algorithm.

Authors: Bilal Ahmed  , M.L Jain
Published: October 2024

This paper is based on the basic steps for analyzing two different hydro mechanical Gates of hydropower plants for an effective and safe design point of view. In an analysis, we found effective and safer results. We used the ANSYS Workbench software to determine these gates' deformation, stress, strength, and reliability for analysis. These gates are also known as sluice gates. In this study, we modeled one using the usual flat-shape geometry. In contrast, the other, as a specific curve-shaped geometry, performed the virtual finite element analysis for better results. An analysis found that the peak stresses induced on the flat gate and curved gate are different, respectively, while the deformation occurred due to peak stresses being less and more, respectively; from these results, It is concluded that the curved gate is a better one.

Metal Matrix Nano Composites (MMNCs) with the addition of nano-particulate reinforcements can be of significance for automobile, aerospace, and numerous applications due to their low density and good mechanical properties, better corrosion and wear resistance, low coefficient of thermal expansion as compared to conventional materials. Designing the metal matrix composite material aims to combine the desirable attributes of metals and ceramics. The present work is focused on studying the mechanical properties of aluminium alloy (7075) with Al2O3 and B4C nanocomposite produced using the stir casting technique and ultrasonic cavitation method. Different % age of reinforcement is used. An ultrasonic cavitation technique is used to achieve a uniform dispersion of nano-particulate Al2O3 and B4C in molten aluminium alloy. Tensile, Hardness, and Impact tests were performed on the samples obtained by the fabrication processes. A structural study will be carried out through a Scanning Electron Microscope (SEM) to know the distribution of Al2O3/B4C Nano particulates in Al alloy.

Additive Manufacturing (AM) is a modern technology that enhances manufacturing by building thin layers of material from digitized (3D) designs, entirely constructed using advanced CAD software. This method facilitates the creation of new types of objects with unique material properties. However, while AM is often hailed as the next industrial revolution, significant challenges remain for its successful commercialization. This project focuses on the microstructural aspects and the dimensional accuracy of the product. Additionally, the paper discusses the slicing algorithm and the material extrusion process in detail.

Schooling-at-home and educating children at home have received increased attention since the COVID-19 pandemic which resulted in abrupt social changes, including stay-at-home protocols and school closures to prevent the spread of infection during the period. We examined the mental health, psychosocial well-being, and loneliness of parents according to whether they had been taking on extra schooling-at-home and child-care responsibilities. We conducted a multi-country cross-sectional online survey nine months into the COVID-19 pandemic in Norway, the UK, the USA, and Australia with a sample size of 1,722. Outcome measures included the General Health Questionnaire 12 (GHQ-12) mental health scale, the Psychosocial well-being (PSW) scale, and the De Jong Gierveld Loneliness Scale (LS). The key explanatory factor was parental and child-care status, which categorised participants based on how many extra child-care or schooling-at-home responsibilities were taken up. Moderator variables included working-from-home status, living arrangements, and demographic covariates. Our sample had 20.0% of parents who reported taking on some or half of the extra child-care responsibilities, and 11.7% reported that they were taking on most of the extra child-care responsibilities. Parents who were taking on most of the extra child-care or schooling-at-home responsibilities had poorer mental health (M = 17.34, SE = 0.40 vs M = 15.47, SE = 0.37, p = 0.002), psychosocial well-being (M = 2.92, SE = 0.05 vs M = 2.72, SE = 0.05, p = 0.011), and loneliness (M = 11.29, SE = 0.31 vs M = 10.33, SE = 0.28, p = 0.019), compared to parents who did not have extra responsibilities. Younger parents and those not living with a spouse reported poorer outcomes. Parents who reported that they were taking on most of the child-caring responsibilities reported the poorest mental health, psychosocial well-being, and highest levels of loneliness. Psychosocial and community support for parents who take on schooling-at-home and education responsibilities is important for the well-being of the parents as well as for their children.
Instructional Methods Used by Secondary School Teachers in Classroom to Develop Students’ English Writing Skills in Iringa Municipality, Tanzania

Published: October 2024

This study examined instructional methods employed by secondary school English language teachers in classroom to develop students’ English writing skills in Iringa Municipality, Tanzania. Specifically, the study sought to assess English language teachers’ understanding of the purpose of English language syllabus for secondary education; to investigate the teaching and learning techniques used by teachers in classroom to develop students’ English writing skills; and to evaluate the effectiveness of the techniques used in developing English writing skills among students. The social-cultural theory and communicative competence theory were adopted to guide the study. The study employed an interpretivism paradigm, qualitative approach and a phenomenological research design. The study involved 33 participants (12 English teachers and 21 FIII students) who were selected purposively from 3 public secondary schools in Iringa Municipality. The data were collected using documentary review, classroom observations, and interviews, and thematically analysed. The findings revealed that teachers had differing understanding of the purpose of the English syllabus. Also, the findings showed that teachers used techniques, such as explanation and demonstration, writing practice and exercise, reading-writing integration, sentence combining, genre-based instruction, and collaborative writing, in teaching English writing skills. Moreover, the study found that the techniques used were ineffective to develop students’ English writing abilities as many students struggled to write in English. The study concludes that the opposing understanding of the purpose of the subject syllabus among teachers limits teachers from effectively using instructional methods to develop writing skills in English among students. Therefore, teachers should be trained on the purpose of the subject syllabus to enable them effectively use instructional methods in a manner that focuses to develop English writing skills among students per requirements of the subject syllabus

Aim: Diabetic polyneuropathy is the most described complication in patients with diabetes mellitus. A significant percentage of these patients experience disabling neuropathic pain (painful diabetic polyneuropathy). Small nerve fibers are primarily responsible for peripheral nociception, but objectively assessing its function is challenging. The primary objective of this study was to explore the task execution and outcomes of intra-epidermal electrical stimulation technique that combines nociceptive detection thresholds (NDT) and evoked potentials (EPs) in patients with diabetes. We compared the results of diabetic patients, both with and without painful diabetic polyneuropathy, with those of healthy controls to explore potential clinically relevant information.
Methods: The NDT-EP method was applied to 38 patients with diabetes (18 with and 20 without chronic painful neuropathy) and 38 age- and sex-matched healthy controls. Individual mean NDTs, psychometric slopes, EP amplitudes, and the effect of the stimuli on EP amplitudes were analyzed and compared between groups using linear regression.
Results: The findings revealed significantly lower detection rates, higher NDTs, and lower psychometric slopes in patients with painful diabetic polyneuropathy than in healthy controls. Both patient groups significantly exhibited lower mean EP amplitudes than healthy controls, which were not linked to pulse amplitudes but influenced by stimulus detection.
Conclusions: This study showed altered NDT-EP outcomes in patients with painful diabetic polyneuropathy. Whereas the task execution, NDTs, and psychometric slopes may provide valuable insights into small fiber dysfunction, pulse amplitudes seemed not differently encoded in neurophysiological responses to intra-epidermal electrical stimulation near the detection threshold compared to controls. Future studies should investigate whether the altered NDT-EP outcomes could quantify small fiber dysfunction in patients with diabetes mellitus. We recommend further exploration of NDT-EP measures in other patient groups with nociceptive dysfunction.
