Published: August 2024

AbstractAimCompare the use and trend of a telemedicine tool for clinical advice among nurses and other Cameroonian healthcare providers and explore its feasibility and accessibility.DesignA comparative observational descriptive study.MethodsThe sample includes all telemedicine users who request advice from volunteer medical specialists in Spain on clinical cases through the telemedicine tool “diagnosis assistance” (DA). It consisted of a total of 296 Cameroonian health professionals (59% women), of whom 77 were nurses. The variables in which the trend was explored (2013–2022) were DAs entered by nurses versus other healthcare professionals, compared by primary specialty, comments and documents attached. Feasibility and accessibility were explored through an anonymous survey.ResultsThere were 2527 DAs between 2013 and 2022, of which nurses introduced 68%. There is an increasing trend in the nurse/other healthcare providers ratio, with significant differences in the chi‐square of the linear trend between 2015 and 2022 (χ2 = 395.05; df = 7; p < .001). The probability that a DA was requested by nurses (PR >1) was observed in all years except for 2014, 2018 and 2019. The most tele‐counselling requested by nurses was in the specialties of internal medicine, obstetrics and gynaecology, and dermatology. The exchange of comments and attachments was mainly conducted among nurses (74.9% and 50.4%, respectively). The users surveyed considered the tool valuable for diagnosis, applicable, with limitations due to cost, Internet quality or lack of time and effective at reducing hospital referrals.ConclusionsTelemedicine for clinical advice has been used mostly and with increasing tendency by nurses, mainly in internal medicine, gynaecology and dermatology, being a useful and feasible resource that can contribute to improving clinical decision‐making by African nurses.ImpactThe study addressed the problem of the shortage of health professionals in Central Africa and the search for alternatives that facilitate decision‐making in this context. Tele‐counselling tools through digital platforms that put Spanish specialists in contact with health professionals in Central Africa are mostly used by nurses working in rural health centres with a growing trend in their use. The research allows us to determine that tele‐counselling tools constitute a well‐accepted resource, which has a positive impact in environments with a shortage of human health resources, favouring the safety of both the nursing professional, through support in decision‐making, and the populations to whom they provide care, who benefit from a multidisciplinary approach to their processes.Reporting MethodThe study has adhered to STROBE guidelines.Patient or Public ContributionNo Patient or Public Contribution.

Published: August 2024

AbstractObjectiveThis article aims to describe a systematic method for tooth color reproduction with ceramics restorations employing artificial intelligence (AI) software named Matisse. It provides a comprehensive analysis of the entire process, beginning with shade‐taking and extending to ceramic application in a complex clinical case in the anterior region—specifically, a single central restoration supported by an implant.Clinical ConsiderationsThe clinical case presented highlights the potential of Matisse software for generating ceramic (inSync‐Jensen Dental, USA) and staining (Miyo‐Jensen Dental, USA) recipes over a zirconia abutment (Katana‐Noritake Dental, Japan). This approach achieves an optimal single central restoration utilizing CAD‐CAM and layering techniques.ConclusionsThe systematic method employing the Matisse software achieved accurate color reproduction for a single central restoration supported by an implant. This result was achieved by the dental ceramist within the first attempt and without seeing the patient in the entire process.Clinical SignificanceThe Matisse AI‐assisted protocol offers a systematic and scientifically grounded method for color reproduction in dentistry for indirect restorations.

Published: August 2024

AbstractBackgroundCurrent research separately analyzed the connection between postpartum depression, fatigue, sleep and infant development. However, depression, fatigue and sleep quality often coexisted as adverse symptoms in postpartum women and influenced infant development together. This study explored the maternal postpartum symptoms on infant growth.MethodsOur study included 224 pairs of singleton full‐term mothers and their infants who underwent routine pediatric outpatient clinics. Latent profile analysis was applied to identify the latent classes based on mothers' postpartum depression, fatigue and sleep profile characteristics. We evaluated the maternal adverse symptoms and infant development using multivariable logistic regressions.ResultsTotally, 224 pairs of eligible mothers (28.85 ± 4.43 years) and infants (30.93 ± 3.26 days) participated in this study. Latent profile analysis identified 3 latent groups: mild (58.04%), moderate (34.37%), and severe (7.59%) postpartum adverse symptoms. Postpartum adverse symptoms were associated with delayed development in the baby's motor level (χ2 = 6.572, p = .037) and weight‐for‐length (χ2 = 9.652, p = .008). After controlling for mother and infant related factors, postpartum adverse symptoms remained a risk factor for infant motor level (odds ratio [OR]: 4.35; 95% confidence interval [CI]: 1.25–15.08) and weight‐for‐length (OR: 5.53; 95% CI: 1.55–19.74).ConclusionsMaternal postpartum depression, fatigue and sleep quality are associated with infant development. Clinically, mothers with these symptoms should be intervened timely to avoid the aggravation of maternal symptoms, which affect baby's development.
The Granger–Johansen representation theorem for integrated time series on Banach space
Authors: Howlett Phil , Beare Brendan K. , Franchi Massimo , Boland John , Avrachenkov Konstantin 
Published: August 2024

We prove an extended Granger–Johansen representation theorem (GJRT) for finite‐ or infinite‐order integrated autoregressive time series on Banach space. We assume only that the resolvent of the autoregressive polynomial for the series is analytic on and inside the unit circle except for an isolated singularity at unity. If the singularity is a pole of finite order the time series is integrated of the same order. If the singularity is an essential singularity the time series is integrated of order infinity. When there is no deterministic forcing the value of the series at each time is the sum of an almost surely convergent stochastic trend, a deterministic term depending on the initial conditions and a finite sum of embedded white noise terms in the prior observations. This is the extended GJRT. In each case the original series is the sum of two separate autoregressive time series on complementary subspaces – a singular component which is integrated of the same order as the original series and a regular component which is not integrated. The extended GJRT applies to all integrated autoregressive processes irrespective of the spatial dimension, the number of stochastic trends and cointegrating relations in the system and the order of integration.
On epistemic black holes: How self‐sealing belief systems develop and evolve
Authors: Boudry Maarten , Hofhuis Steije 
Published: August 2024

AbstractMany pseudosciences, conspiracy theories and other unfounded belief systems have a self‐sealing nature, being equipped with defence mechanisms and immunizing strategies that protect them against counterevidence and criticism. In this article, we discuss the existence of ‘epistemic black holes’, belief systems which posit intelligent agents that are deliberately evading detection and thus sabotaging any investigation into their existence. These belief systems have the remarkable feature that they predict an absence of evidence in their favour, and even the discovery of counterevidence. The most obvious instances of such epistemic black holes are unfounded conspiracy theories, but examples crop up in other domains as well. We outline the development and cultural evolution of epistemic black holes, drawing from a number of case studies. Most importantly, because of their self‐sealing character and resilience to counterevidence, epistemic black holes suffer from a recurring problem of arbitrariness and proliferating alternatives. Shedding light on how epistemic black holes function can help to inoculate people against their enduring allure.

Authors: Tan Quanwei , Xue Guijun , Xie Wenju 
Published: August 2024

The regulation strategy of a district heating system is adjusted based on accurate heat load prediction, which not only effectively reduces energy consumption but also improves system efficiency and user comfort. In order to improve the accuracy of heat load forecasting, a heat load forecasting model considering the two-dimensional change of time series is introduced in this paper. Firstly, the original heat load data is denoised by SVMD decomposition, and several stationary and regular modal components are obtained. Then, three strategies were used to enhance the BWO algorithm, and the IBWO-TimesNet prediction model was established to extract the hidden information of time series data from a two-dimensional perspective. Finally, the prediction performance of the model is evaluated in detail through case analysis. The results show that MAE, RMSE and R2 of SVMD-IBWO-TimesNet model are 0.647, 1.190 and 99.1%, respectively. Compared with other mainstream prediction models, this model has higher prediction accuracy. In addition, even if the training samples are reduced, the SVMD-IBWO-TimesNet model can still effectively predict the heat load and has strong generalization ability. Therefore, the performance of the model is verified, which provides a reference for the accurate control of heat load. Practical application Heat load forecasting is a vital task particularly in relation to its impact on the management of building energy efficiency. The contribution of this paper is to provide a heat load forecasting model based on advanced algorithms and data analysis. This insight derived from advanced modelling will assist professionals in the pursuit of more accurate prediction of the heat needs of buildings, thereby optimizing the design and operation of heating systems. The practical application of this technology could save energy costs, reduce carbon emissions, and improve the comfort and sustainability of buildings.
Online Mental Health Peer-support Forums for Youth: An Exploratory Study on Stakeholder Perspectives
Authors: Achar Meghna , Mehrotra Seema 
Published: August 2024

Background: Youth in India carry a large proportion of the global burden of mental health disorders and subclinical distress. They prefer to seek mental health support from informal sources. One such source—online mental health peer-support forums (OMHPSFs)—is under-researched. This study aims to explore the perspectives of youth and mental health professionals and counselors (MHP&Cs) in terms of the scope and utility of and inclination to use OMHPSFs for maintaining youth mental well-being. Methods: An exploratory, cross-sectional, mixed-methods study was conducted. A total of 141 Indian nationals aged 18–29 years were enrolled using convenience sampling and administered a survey. In the qualitative phase, six youth and seven MHP&Cs were interviewed. Results: Ninety (63.8%) and 106 (75.2%) participants indicated a high inclination to use OMHPSFs to seek and provide support, respectively. More than three-quarters of the surveyed youth stated that OMHPSFs should be a space for emotional and informational support to deal with life challenges. A total of 127 (90.1%) participants reported that OMHPSFs would be useful to find out how others their age deal with similar life challenges. A thematic analysis of interviews revealed that anonymity, accessibility, appeal, and ease of use enhance youth inclination toward OMHPSFs. The role of MHP&Cs in training, supervision, and moderation and strategies to popularize OMHPSFs were outlined and recommended. Conclusion: Sampled youth showed a high inclination to use OMHPSFs to seek and provide mental health support to their peers. Stakeholders consider OMHPSFs as relevant in scope and utility to alleviate mental health concerns among Indian youth.

Published: August 2024

Background: Research on event-related potentials (ERP) in addiction highlights the importance of cognitive ERP markers, such as P300 and error-related negativity (ERN), in distinguishing between alcohol-dependent patients and healthy controls. We aimed to develop and validate ERP paradigms utilizing culturally validated stimuli to evoke P300 and ERN for the Indian population. Methods: In a cross-sectional study, 16 alcohol-dependent patients and age-matched healthy controls were recruited. For P300, we designed a visual oddball (Go/No-Go) task using culturally appropriate alcohol and non-alcohol-related images. To study ERN, we used the Assessing Neurocognition via Gamified Experimental Logic (ANGEL) task, developed in India, integrating its “game” levels to capture error monitoring with fewer trials. A 32-channel EEG-ERP system was used for data acquisition. Results: Participants showed high engagement in the visual Go/No-Go task, with 94.4% accuracy. The P300 difference wave showed significantly higher amplitudes ( p = .01, Cohen’s d = 0.97) and latencies ( p < .001, Cohen’s d = 1.62) in patients compared to controls at the Pz electrode. No significant group differences were found in accuracy or reaction times for frequent and rare stimuli. In the ANGEL task, patients had a significantly lower ERN difference wave amplitude at the Pz electrode than controls ( p < .001, Cohen’s d = 1.47), with no latency differences. Task accuracy was lower, and reaction time was longer in patients. Conclusions: The visual Go/No-Go task and the ANGEL task are promising tools for understanding the neurocognitive mechanisms underlying alcohol dependence in the Indian context.

Published: August 2024

Objective We conducted a systematic review of the literature on online health memes to (a) detect and describe the available research, (b) identify key findings, and (c) delineate future research needs/opportunities. Data Source Databases, communication and public health journals, and ancestry search. Study Inclusion and Exclusion Criteria Empirical studies, in English, published in peer-reviewed academic journals, and focused on memes to discuss health-related topics. Data Extraction We scrutinized 357 empirical articles and included 35. Data Synthesis Descriptive summary of the locations where studies were conducted, the health topics addressed, theories and methods used, features of memes analyzed, study outcomes, and researchers’ challenges. Results Most studies were conducted in the USA (n = 14); focused on COVID-19 (n = 15); were a-theoretical (n = 19); and quantitative (n = 19). Most explored the themes and use of the memes available online (n = 19); compared meme variations (n = 12) by health issue, content, or participants’ group; examined meme’ effects on health outcomes (n = 1); or evaluated memes as part of a health campaign (n = 3). We summarized the studies’ limitations and key findings. Conclusions Memes are a promising message strategy for health promotion and education, but more research is necessary. Considering the information retrieved, we provide five specific recommendations for future research directions when studying health memes, including suggestions on the multiple health issues to address and promising theories to adopt and expand.
Optimizing an auxetic metamaterial structure for enhanced mechanical energy absorption: Design and performance evaluation under compressive and impact loading
Authors: Nickabadi Saeid , Sayar Majid Askari , Alirezaeipour Saeid , Ansari Reza 
Published: August 2024

Auxetic metamaterials, characterized by their negative Poisson’s ratio, offer promising prospects for utilization in absorbing energy during quasi-static compressive loading as well as in applications requiring impact energy absorption. The optimization of auxetic structures’ geometrical parameters can improve their performance. This research aims to optimize the design of an auxetic structure for maximum specific energy absorption and investigate its behavior under quasi-static compressive and high-velocity impact loading. The geometrical parameters of the cross-petal auxetic structure are optimized using genetic algorithm and a neural network surrogate model. The behavior of the optimized auxetic structure is examined in quasi-static compressive loading and compared with that of the basic auxetic structure using finite element simulations. The optimized auxetic structure is then evaluated in high-velocity impact loading as the core of a sandwich panel, with two plates placed in the front and rear. Simulations of projectile impacts at velocities ranging from 100 to 250 m/s reveal the sandwich panel’s behavior. Results indicate a 69.82% increase in specific energy absorption capacity for the optimized auxetic structure as compared to the basic structure in quasi-static compressive loading. In high-velocity impact, the sandwich panel with the optimal auxetic core outperforms the one with the basic core. At velocities more than the minimum perforation velocity, the core contributes about 64%–67% of the total absorbed energy by the sandwich panel.

Authors: Li Yanyan , Zhuang Zhenhuang , Si Huaxin , Liu Qinqin , Yu Jiaqi , Zhou Wendie , Huang Tao , Wang Cuili 
Published: August 2024

Purpose Two-sample Mendelian randomization methods were used to explore the causal effects of cognitive reserve proxies, such as educational attainment, occupational attainment, and physical activity (PA), on biological (leukocyte telomere length), phenotypic (sarcopenia-related features), and functional (frailty index and cognitive performance) aging levels. Results Educational attainment had a potential protective effect on the telomere length ( β = 0.10, 95% CI: 0.08–0.11), sarcopenia-related features ( β = 0.04–0.24, 95% CI: 0.02–0.27), frailty risk ( β = −0.31, 95% CI: −0.33 to −0.28), cognitive performance ( β = 0.77, 95% CI: 0.75–0.80). Occupational attainment was causally related with sarcopenia-related features ( β = 0.07–0.10, 95% CI: 0.05–0.14), and cognitive performance ( β = 0.30, 95% CI: 0.24–0.36). Device-measured PA was potentially associated with one sarcopenia-related feature ( β = 0.14, 95% CI: 0.03–0.25). Conclusions Our findings support the potential causality of educational attainment on biological, phenotypic, and functional aging outcomes, of occupational attainment on phenotypic and functional aging-related outcomes, and of PA on phenotypic aging-related outcomes.
The relationship between self-care behaviours regarding arteriovenous fistula and the fear of fistula failure in individuals receiving haemodialysis treatment
Authors: Alabacak Şahin , Arslan Selda 
Published: August 2024

Background: Many problems regarding the self-care behaviours of haemodialysis patients are recognised; however, the fear experienced by the patients cannot be adequately explained. Aims: This study was conducted to determine the relationship between self-care behaviours related to arteriovenous fistula and fear of fistula failure in individuals receiving haemodialysis treatment. Methods: In this descriptive and relational study, 259 patients who met the inclusion criteria constituted the sample of the study. A multiple regression analysis enter model was used to evaluate the predictive power of the Self-Care Behaviours in Arteriovenous Fistula Scale. Results: It was found that the primary source of fear related to the fistula was the fear of fistula failure with a rate of 79.5%, and the patients who had this fear had a lower mean self-care scale score. The variables account for 12% of the self-care situation, and it is seen that the model is significant. Conclusions: It was concluded that increasing the fear of failure decreased the self-care score. This study is important for raising awareness among nurses regarding the fear of fistula failure. Nurses must provide appropriate care for vascular access and try to alleviate patients’ anxiety and fears by listening to them.
