Unleashing the potential of eHealth in outpatient cancer care for patients undergoing immunotherapy-a quantitative study considering patients' needs and current healthcare challenges.

The use of online information and communication is globally increasing in the healthcare sector. In addition to known benefits in other medical fields, possible specific potentials of eHealth lie in the monitoring of oncological patients undergoing outpatient therapy. Specifically, the treatment with immune checkpoint inhibitors (ICI) requires intensive monitoring due to various possible negative side effects. The present study explores cancer patients' perspectives on eHealth and demonstrates how eHealth applications, from the patients' point of view, can contribute to further improving outpatient immunotherapy. Our multicenter study was executed at the university hospitals in Bonn and Aachen. A structured questionnaire was distributed to patients receiving outpatient immunotherapy. Contents addressed were (1) the patients' attitude towards eHealth applications, (2) the use of modern information and communications technologies (ICT) in (2a) everyday life and (2b) health-related information search including eHealth literacy, (3) the use of internet-enabled devices as well as (4) socio-demographic data. 164 patients were included in the study, of whom 39.0% were female and 61.0% male and the average age was 62.8 years. Overall, there was a high distribution of internet-enabled devices for everyday use and a great interest in integrating eHealth applications into outpatient immunotherapy. The assessment of eHealth potentials significantly depended on age. The younger participants demonstrated a broader use of modern ICT and a higher affinity for its use in outpatient immunotherapy. In some aspects, level of education and gender were also relevant factors influencing the patients' view on eHealth. This study demonstrates the potential for further integration of eHealth applications into outpatient immunotherapy from the patients' perspective. It indicates a dependency on age and educational level for the further integration of eHealth into patient care in oncology. Due to particular patient needs regarding age, level of education, gender and other subgroups, specific education and training as well as target-group specific digital health interventions are necessary to fully utilize the potentials of eHealth for outpatient immunotherapy. Future studies are required to specifically address target-group specific usability of eHealth applications and eHealth literacy, as well as to address information security and data protection.

SensorHUB – a Novel, Open-source Software Stack for Enhanced Accessibility and Secure Interoperability in IoT Project Management

Abstract. The Internet of Things (IoT) seeks to achieve seamless device connectivity and data sharing, thereby enhancing automation, efficiency, and insights in various fields of application. By delivering real-time data, IoT is essential for systems that aim to model and map the physical world to digital formats, such as digital twins or metaverses. In the recent years, there has been a surge in high-quality commercial IoT products available to various sectors.

Nonetheless, despite technological progress, the adoption of open and standardized IoT software solutions is still predominantly seen among technology-affine groups or within research and development initiatives. We propose the sensorHUB, a novel IoT stack, which builds upon the Open Geospatial Consortium’s (OGC) data standard SensorThings API and enhances existing solutions towards more accessible, production-oriented solutions for diverse application domains and user groups. Key features include the provision of a new, state-of-the-art graphical user interface for managing data flows and the access to related software modules, and a secure and flexible user and access management.

Acceptability and Usability of Mobile Health Application for Enhancing Treatment Adherence in Latent TB Patients

Background: Mobile health interventions showcase effectiveness for improving treatment adherence among Latent TB Infection (LTBI) patients. However, there is a paucity of evidence regarding their acceptability and usability. This study aimed to assess the initial acceptability and usability of a mobile health application that has been designed to ensure treatment adherence in LTBI patients. Methods: A descriptive study was conducted to assess the acceptability and usability of a mobile health application, “My Treatment Friend”. A total of 82 LTBI patients were selected, and access to the application was given to them. This application provides support to LTBI patients in reporting daily medication and side effects. The basic demographic characteristics of the participants were collected through a Google form-based questionnaire. The acceptability and usability of the application were assessed using the Likert scale questionnaire and SUS tool, with samples of n=44 and n=20 participants, respectively. Results: LTBI patients found the mobile application acceptable and feasible, with an SUS score of 73, which comes under Grade B as per the SUS score sheet. The majority believed that the app was very simple to use and easy to understand. However, there is a requirement to add more features that can enhance the acceptability and usability of the application. Conclusion: The study showed the importance and usefulness of mobile applications to assist LTBI patients in finishing their prescribed treatment courses of action. Additionally, it highlights how crucial it is to build future applications using user-centered design. User-centered design may play an important role in designing mobile applications and ensuring effective engagement and satisfaction among users.

Criminal Prohibitions when Using Mobile Applications

The article summarizes interim results of a research performed under the project of the Russian Science Foundation focusing on criminal law risks of using mobile applications. These risks can be of two types: the risk of being held criminally liable and the risk of being victimized by the criminal activities of others. The second type of risk is better defined because it is addressed in the context of preventing crimes committed using information and telecommunications networks or in the field of computer information in general. The first one implies not only situations when a user intentionally causes harm through a mobile application, but also cases where people do things, the public danger and wrongfulness of which is not obvious to them. Such persons usually have no desire to violate criminal law but do so failing to understand the unlawfulness of their actions due to the specific environment and technological features. Therefore, the ultimate goal of this project (at the next step) is to ensure safety of mobile application users, including inadmissibility of their unjustified criminal liability, through the development of recommendations on the rules of behavior when using relevant technologies. The purpose of the work within the framework of the presented scientific article is to determine the state of use of mobile applications (characteristics of mobile Internet culture) and those criminal law regulations that may be consciously or unconsciously violated by users of mobile applications. To achieve this goal two sociological surveys were conducted among users of mobile applications to determine how they use their mobile devices. The provisions of the criminal law and the materials of criminal cases were analyzed in order to understand what crimes can be committed by users of mobile applications who actually did not want and did not understand that they were violating the criminal law.

The WWM application is perceived as a potential approach to increase physical activity and functioning among people with stroke in Benin.

More Than Just a “Bad” Online Experience: Risk Factors and Characteristics of Catfishing Fraud Victimization

ABSTRACT Research focusing specifically on people who have been catfished online, or deceived in some way, but maybe not defrauded out of money is relatively scarce. The current study sought to add to the literature in this area by surveying social media and dating application users about their catfishing victimization experiences (n=1,511). Fourty-four percent had been catfished in the last 5 years. Common characteristics of those who had been catfished include the catfish reaching out first, a short duration of communication, and asking for money, among other characteristics. The lifestyles/routine activities (LRAT) framework and self-control were utilized to examine potential risk factors for catfishing victimization. Both online and offline behaviors were found to influence catfishing risk, suggesting the LRAT can be applied to this type of victimization. Implications for policy application and prevention of catfishing fraud are discussed.

Disentangling the influence of mobile learning usability and its determinants–PLS-SEM and importance-performance investigation

Today, numerous mobile learning applications are used to enable learning during the working process or on-the-go. However, few insights that are available regarding mobile application usability (MAU) and its determinants in the context of mobile learning. More specifically, there is a critical need to disentangle the determinants of MAU and their overall impact on MAU while also acknowledging the possible motivational consequences. Therefore, we developed a theoretical model of MAU, its determinants, and its consequences. By utilizing a free simulation experiment, we investigated the role of MAU in the domain of mobile learning. We used structural equation modeling to analyze the theoretical model. The results show a significant influence of MAU on mobile learning compatibility, performance expectancy, and self-efficacy. The results also indicate that compatibility acts as a partial mediator of usability on performance expectancy. Finally, we conducted an importance-performance analysis that reveals key usability insights: UI output, the most critical factor, underperforms, highlighting a major improvement area. UI structure and application design also need enhancement. In contrast, UI input and application utility perform well despite lower importance, with UI graphics showing adequate performance despite being least crucial. The present paper contributes to the discussion concerning MAU and its impact on mobile learning, while delivering formative insights of MAU for mobile learning applications.

Widespread presence of gut bacterium Glutamicibacter ectropisis sp. nov. confers enhanced resistance to the pesticide bifenthrin in tea pests

The gut microbiota in Lepidopterans demonstrates variability and susceptibility to environmental influences, thereby presenting opportunities for the acquisition of novel bacterial strains. Ectropis grisescens (Warren), a notorious Lepidopteran pest, causes substantial damage to tea crops. Prolonged application usage of bifenthrin for the management of this pest has led to increased resistance. This study aims to investigate the relationship between the gut microbiota, as shaped by long-term pesticide use and the resistance of E. grisescenes. We employed high-throughput sequencing of the 16S rRNA gene to analyze the gut microbiota compositions in bifenthrin-resistant (BIF-R) and bifenthrin-sensitive (BIF-S) strains. Bifenthrin-degrading strains were isolated from the gut of BIF-R using selective media. The degradation efficiency and products of bifenthrin by the key strain were detected using gas chromatography (GC) and gas chromatography–mass spectrometry (GC–MS). The effect of the key strain on host resistance was verified in vivo. Finally, the distribution and abundance of the degrading bacterium, in conjunction with insect's pesticide resistance, were assessed in 22 distinct E. grisescens populations. Bifenthrin resistance was diminished in BIF-R following the removal of gut bacteria, a phenomenon not observed in BIF-S. Subsequent high-throughput amplicon sequencing revealed distinct structural differences in the gut microbiota between the two groups, notably an increased abundance of Glutamicibacter in BIF-R. A newly identified bacterial strain from BIF-R larvae, Glutamicibacter ectropisis (B1), demonstrated bifenthrin degradation efficiency and the main metabolite was 2,4-di-tert-butylphenol. Inoculation of B1 into BIF-S larvae conferred increased resistance to bifenthrin. Furthermore, we confirmed the prevalence of B1 in the gut of E. grisescens across 22 tea-growing areas in China. A positive correlation was observed between the absolute abundance of B1 and bifenthrin resistance in E. grisescens. This study represents the first identification of a novel gut bacterium, G. ectropisis, which mediates host resistance through the direct degradation of bifenthrin. This mechanism has been widely validated across 22 distinct populations.

Dating Anxiety and Loneliness in Online Dating: The Moderating Effect of Gender

In the digital age, online dating applications have revolutionized the way young adults form romantic connections, providing both opportunities and challenges. Understanding the psychological impacts of these platforms is crucial. Young adults, while navigating romantic pursuits and various developmental challenges, are susceptible to feelings of loneliness. Dating anxiety is a significant factor that can exacerbate loneliness within this demographic. Moreover, gender differences may influence individuals' experiences in dating situations. This research aims to explore the relationship between dating anxiety and loneliness among users of dating applications and to examine the role of gender as a moderating variable in this relationship. The study employs a quantitative correlational approach, incorporating demographic data and two scales: the Dating Anxiety Scale and the UCLA Loneliness Scale 3. The research participants consist of 250 early adults aged 20-34 who actively use online dating applications. Data analysis involves descriptive analysis and moderation analysis using the Jamovi software. The research findings indicate a significant direct relationship between dating anxiety and loneliness (p less than 0.001). Furthermore, gender was found to have no significant impact on loneliness (p more than 0.05), and the interaction between dating anxiety and gender was not significant (p more than 0.05). This suggests a uniform impact among both genders in the relationship between dating anxiety and loneliness. The study highlights the complex dynamics influencing loneliness among online dating application users. The findings enhance theoretical understanding of how dating anxiety relates to loneliness. Practically, these insights can help developers create features that reduce anxiety and loneliness. Future research should identify other factors influencing these dynamics to further enrich theoretical and practical knowledge in this field.
