Authors: Pikul Maksym , Gordiichuk Prokip , Stakhovsky Eduard 
Published: August 2024

Aim:
This study aims to assess the effectiveness of urothelial cancer treatment in Ukraine, utilizing population-based data from the National Cancer Registry. The primary goal is to evaluate trends and approaches to therapy, with a focus on overall survival rates in patients with urothelial tumors.

Materials and methods:
A retrospective cross-sectional analysis was conducted based on the National Cancer Registry, involving 12 698 patients (2008–2020) with urothelial tumors of the upper urinary tract (UTUC) and bladder cancer (BC) who underwent surgical treatment. Demographic indicators, surgical interventions, complications, and survival rates were analyzed.

Results:
The average age for all patients was 70 years. The number of patients undergoing radical treatment was 1820 (15%) among BC and 573 (59%) among UTUC. The 30-day readmission rate was low for both, with a slightly higher preference for UTUC (2.3 vs. 4.6%). Whereas grade III or higher Cl-Dindo complications were seen in only 0.2% of cases. Notable findings include low frequency of neoadjuvant (7%) and adjuvant chemotherapy (28%) among patients with invasive urothelial carcinomas. Median eGFR for invasive UTUC before and after surgery was 63.2 and 51.4 ml/min, respectively (P=0.00054). The directly opposite trend was seen in BC—61.2 and 68.7 ml/min, respectively (P=0.0026).
For BC, the overall survival rates by stages were: I—73%, II—49%, III—18%, and IV—11% (χ2=1807.207; P=0.000001). As for UTUC, the 5-year overall survival rates corresponded to the literature data, but there was a pronounced negative trend towards a decrease in this indicator after a 10-year period for all stages (χ2=146.298; P=0.000003).

Conclusion:
The study emphasizes the importance of effective systemic treatments, adherence to treatment guidelines, and the need for multidisciplinary consultations among Ukrainian patients with urothelial cancer.

Background
Online support groups afford new opportunities to help individuals affected by HIV/AIDS to seek social support from peers. The study aimed to understand the willingness and associated factors of joining online support groups among men who have sex with men living with HIV.

Methods
The study followed a mixed methods approach, with qualitative in-depth interviews followed by a quantitative cross-sectional survey in 3 cities of Shandong Province, China, from 2019 to 2020. The in-depth interviews were audio-taped, transcribed verbatim, and analyzed using a thematic approach. In the quantitative analysis, explanatory variables included sociodemographic, behavioral, clinical, psychological, and demand factors. Univariate and multivariable logistic regressions were conducted to examine the associated factors of willing to join online support groups.

Results
A total of 576 and 20 participants were included in the quantitative survey and qualitative interviews, respectively. Only 24.7% (142 of 576) of participants in the quantitative study were willing to join the online support group. Multivariable analysis showed that the associated factors included income level, sexual orientation, and availability of information. The barriers to joining online support groups included privacy disclosure concern and psychological pressure exposed to HIV-related information. Facilitators included information acquisition, mutual medication reminding, and emotional support.

Conclusions
Men who have sex with men living with HIV in China had relatively low willingness to join the online support groups. This study highlighted the importance of safeguarding privacy, involving professional mental health providers, and providing high-quality information when establishing online support groups for people living with HIV.
Trans-Golgi network-lipid droplet contacts maintain the TGN integrity and function via lipid transfer activities of VPS13B
Authors: Du Yuanjiao , Xiong Juan , Ji Wei-Ke 
Published: August 2024

AbstractWhile the physical interactions between the Golgi apparatus (Golgi) and lipid droplets (LDs) have been suggested through system-level imaging, the bona fide and functional Golgi-LD membrane contact sites (MCSs) remain largely uncharacterized. Here, we demonstrate that vacuolar protein sorting-associated protein 13B (VPS13B) mediates trans-Golgi network (TGN)-LD interactions. VPS13B is specifically accumulated at TGN-LD MCSs with its C-terminal region targeting LDs via an amphipathic helix while a putative WD40 module and a C-terminal Pleckstrin homology (PH) domain independently recognizing TGN via directly binding to Rab6. A putative lipid transfer domain (LTD) at the N-terminal portion of VPS13B binds glycerophospholipidsin vitro. VPS13B suppression results in severe fragmentation of the TGN, an effect that can be almost completely rescued by the expression of VPS13B-LTD. Collectively, our findings demonstrate that VPS13B mediates lipid transfer at TGN-LD MCSs to maintain TGN integrity and function.

ABSTRACTBackgroundThe prevalence of obstructive sleep apnea (OSA) is higher in patients with primary aldosteronism (PA), while elevated renin activity after treatment is associated with a lower risk of cardiovascular events. However, the association of PA with degree of OSA remains unclear and it is not known whether elevated renin activity in PA patients is associated with change in apnea condition.MethodsCross-sectional relationships between PA (n=176) and degree of OSA classified by apnea-hypopnea index (AHI) with use of an apnomonitor were investigated, with the results compared with those obtained with non-PA patients (n=418). Additionally, the effects of elevated renin activity on change in AHI were prospectively examined in 45 patients with PA.ResultsPatients with PA were found to be significantly associated with severe OSA even after adjustment for other clinical risk factors (odds ratio 2.08, 95% confidence interval 1.09-3.95, p = 0.025) as compared to those without PA. Furthermore, the logarithm of the renin activity after treatment and change in AHI before and after treatment were significantly negatively correlated, with Pearson’s correlation coefficient (r = -0.364, p = 0.014).ConclusionsSevere OSA is more commonly seen in PA patients with hypertension as compared to patients without PA, and elevated renin activity may contribute to improvement of sleep apnea in patients with PA.

AbstractBackgroundOnline education gained its popularity in the education system during the COVID-19 pandemic lockdown. The online platform, including social media, was institutionalized globally for the purpose of tutoring to keep the education process ongoing under feasible circumstances. However, the post-pandemic continuation of online education and prolonged usage of electronic devices imposed a greater risk of health issues related to sensory impairment. Our study aimed to determine the impact of online education on students’ hearing status and its associated factors.MethodsA cross-sectional study was conducted among 1030 students of 11th grade and above who were undergoing online education in Dhaka and Chattogram. Data were collected through the online administration of a structured questionnaire containing questions on sociodemographic status, family history of diseases, personal history of comorbidities, information related to screentime exposure, and SSQ-12 (Speech, Spatial, and Qualities of Hearing -12) scale. Descriptive statistics, Pearson’s chi-square test, two independent sample t-tests, and multiple linear regression analysis were employed to obtain the results.ResultThe mean SSQ score of the study participants was 7.74±1.37. In bivariate analysis, gender, family income, family history of diseases (e.g., obesity, headache, hearing problem), personal history of diseases (e.g., obesity, insomnia), device type (mobile/tablet, computer), average daily screen time with sound, and break pattern during online learning were significantly (p<0.05 for all) associated with hearing status. In multivariate analysis, being female (coefficient -0.293, p=0.001), using mobile/tablet (coefficient -0.836, p=0.001), and continuous screen use (coefficient -0.348, p=0.003) were significantly associated with poor hearing status.ConclusionThis current study indicates the detrimental effect of online education on the hearing of young students in Bangladesh. Future studies should explore the long-term hearing effects of online education and guide the policy makers towards necessary preventive approaches.

Published: August 2024

Purpose
This paper aims to examine the use of physical and streaming documentary film collections available in a mid-sized academic library, specifically relating to the length of time that documentary films may remain relevant for curricular use.

Design/methodology/approach
The authors defined documentary film for the purposes of the study and created data sets of our non-fiction film holdings. They weeded out titles that could not be defined as documentaries and ran use reports for streaming and physical collections. They also used Power BI to visualize the data more clearly.

Findings
The authors found that documentary films could remain useful for 25 years, with certain films remaining relevant even longer.

Originality/value
These findings indicate that purchasing or licensing streaming documentary film packages provides value, including older content. In addition, the authors will continue to make purchases of physical DVD or Blu Ray content when necessary and keep these collections up to 30 years before heavily weeding them.

Published: August 2024

PurposeThe effects of the COVID-19 outbreak on the construction industry were formidable and far-reaching, as the construction sector is a major contributor to the gross domestic product (GDP), which balances various sectors of the global economy, and to infrastructure growth, which is a primary gauge of a nation’s advancement. The outbreak led to workforce disruptions, worker deficits, dwindling efficiency, elongated project durations, and scarce opportunities for training and mentorship, and despite endeavors to mitigate these challenges, construction timelines experienced significant interruptions. Various researchers have pinpointed contributing elements, but few have constructed a predictive model to gauge the degree of impact.Design/methodology/approachTherefore, this research intends to fill by introducing an ordinal logistic regression method to forecast the impacts of a pandemic or other similar type of crisis. To achieve this, an online survey was developed and distributed to collect the perceptions of the construction engineers and managers about the diverse contributors to the exceeding project timelines during the COVID-19 pandemic outbreak.FindingsFindings from this study indicate that financial liquidity, modifications to original plans, delays in securing governmental clearances, and a shortage of competent labor have medium-to-high levels of impact on project schedules.Originality/valueThis study will furnish decision-makers with crucial knowledge that will give them the tools to refine their strategies and judiciously allocate resources to overcome the unique hurdles encountered by various construction segments and will enhance the industry's capability to respond more effectively to challenges inherent in this type of crisis.

Authors: Wang Xu 
Published: August 2024

Purpose
The global COVID-19 epidemic has posed significant challenges to the development of innovation and entrepreneurship education in Chinese and foreign universities, and the application of artificial intelligence generated content (AIGC) technology has presented both opportunities and challenges to its development. The purpose of this study is to summarize advanced experiences and models of new engineering innovation and entrepreneurship education development in Chinese and foreign universities, as well as to analyze the influencing factors. Taking the sustainable development goals (SDGs) into account, this study qualitatively proposes enhancement paths and improvement suggestions based on the application of AIGC technology, providing a reference for promoting the sustainable development (SD) of innovation and entrepreneurship education in Chinese universities.

Design/methodology/approach
By using the qualitative comparative analysis (QCA), this paper studies the interaction mechanism between the influencing factors of innovation and entrepreneurship in universities under the background of SDGs. This paper selects 12 representative universities with different cultures and strengths. Meanwhile, this paper analyzes the content of 2,535 publications on innovation and entrepreneurship education and summarizes seven influencing factors as comparison criteria. Then, this paper codes, summarizes and uses configuration to assess the primary factors influencing the development of innovation and entrepreneurship in colleges and universities at home and abroad.

Findings
On the quality of new engineering innovation and entrepreneurship education, comprehensive, diverse influencing factors and upgrading paths are obtained. Furthermore, this research proposes that the SD of innovation and entrepreneurship education in universities should make effective use of “AI plus education” and actively construct practical and teaching platforms. Meanwhile, the ChatGPT is being used to strengthen the innovation and entrepreneurship curricular system and talent training mode. The research also makes recommendations for improving teachers’ ability to acquire intelligent tools and promotes three-way teaching modalities of “teacher-AI-student” by taking into account the influence of various aspects.

Originality/value
This research uses the QCA research method, which analyzes not only influencing factors on the SD of innovation and entrepreneurship education but also explores the interaction mechanisms among factors. Furthermore, the research incorporates SDGs and AIGC technology application scenarios into the field of domestic innovation and entrepreneurship education, which will be helpful in SDGs of innovation and entrepreneurship education on both theoretical and practical levels.
#Fakefamous: how do influencers use disinformation to establish long-term credibility on social media?
Authors: Bahar Varqa Shamsi , Hasan Mahmudul 
Published: August 2024

PurposeCredible influencers play a key role in shaping the views and preferences of social media users. However, many influencers intentionally use disinformation (e.g. false narratives) to deceive users and gain their trust. This can have serious repercussions, not only for the firms that associate with these influencers but also for users. Further, and alarmingly, many influencers who use disinformation can sustain their credibility over time. This research explores how influencers use disinformation to establish long-term credibility on social media.Design/methodology/approachDrawing on self-presentation theory, we use an in-depth qualitative case study to address our research question, primarily relying on archival data obtained from multiple sources.FindingsOur findings suggest that three stages of self-presentation are required to establish influencer credibility based on disinformation: backstage (preparing to deceive), experimentation (testing deception), and frontstage (launching deceptive ideas on a large scale). We also find that when fraudulent influencers simultaneously weaponise a counterculture and mindfully encase disinformation, users view them as highly credible.Practical implicationsWe offer practical suggestions for regulating fraudulent influencers, including enacting fact-checking procedures, using IT artefacts as reliability signals, and building awareness programmes to develop vigilance in social media communities.Originality/valueWe contribute to self-presentation theory by adding experimentation as a critical stage in developing disinformation that works for long periods. We also contribute to the literature at the intersection of social media influencers and disinformation research by revealing why social media users believe in fraudulent influencers.
