BackgroundDoege–Potter syndrome, characterized by solitary fibrous tumors and non‐islet cell tumor hypoglycemia, is rare. Here, we report a case of Doege–Potter syndrome in which retroperitoneal tumor resection was performed with continuous intraoperative blood glucose monitoring.Case presentationA 37‐year‐old man presented with hypoglycemia‐related symptoms, and a 10 × 12 × 9 cm tumor was found in his right kidney. Following tumor resection, insulin secretory abnormalities improved, and intraoperative blood glucose monitoring showed no hypoglycemic events. High levels of insulin‐like growth factor‐II confirmed the diagnosis of an insulin‐like growth factor‐II‐producing tumor with non‐islet cell tumor hypoglycemia. Postoperative serum insulin‐like growth factor‐II levels normalized, with no recurrence observed over 3 years.ConclusionsThis case highlights the rarity of primary retroperitoneal Doege–Potter syndrome, emphasizes the safety of intraoperative blood glucose levels during surgery, and suggests rapid recovery of insulin secretion postoperatively.

AbstractIn conducting an extensive examination, we scrutinize the efficacy of algorithmic trading strategies applied to Futures CopperMainContinuous in the Shanghai Futures Exchange, utilizing a comprehensive data set spanning from January 2020 to December 2022. To mitigate the potential risk of data‐snooping bias—the probability that any favorable results may inadvertently arise from random events rather than the inherent value of the strategies employed to generate these results—our study prudently conducts a reality check and advanced assessments. Throughout the evaluated period, the benchmark demarcation between the in‐sample and out‐of‐sample stages is established in February 2022. Regrettably, our meticulous exploration fails to identify any successful or advantageous algorithmic trading strategies within these categories, particularly following the systematic elimination of data snooping bias. These results underscore the intrinsic challenges in accurately identifying and implementing profit‐generating algorithmic trading strategies within the volatile and intricate futures market.

AbstractLoad balancing, a critical aspect of cloud and cloud‐based applications, is a major challenge that demands our attention. Due to the increasing dynamic workloads, load balancing becomes more important in the cloud. One of the hyperscale models that stands out for its ability to efficiently balance load by scaling the demands and allocating resources is the Loxi‐Load‐Balancer (LLB). This paper explores explicitly LLB's application in the context of 5G‐Edge IoT applications based on Kubernetes. LLB's unique features, such as its open‐source nature for cloud‐native loads, its use of eBPF as the core engine to avoid adding additional software modules to configure the kernel, and its ability to change its services using the existing layers, set it apart from other load balancers. These features provide high security, observability, and networking. This paper delves into how LLB is used for load balancing in Kubernetes to increase speed and provide flexibility and customizable services. LLB automates all the internal and external administrations concerning monitoring, deployment, scaling, migration, routing, configuration, and resource allocation. This paper focused on developing an efficient resource allocation management system by load balancing using Loxi‐Load‐Balancer‐extended Berkeley Packet Filter (LLB‐eBPF). Detailed information about the LLB‐eBPF‐Kubernetes is given in this paper to help you understand the basics of LLB, eBPF, and Kubernetes.

AbstractIntroductionMany adolescents are in their first romantic relationship; at the same time, depressive symptoms generally increase during this developmental stage. In adults, equity of support in romantic relationships is associated with less depressive symptoms—especially in female partners, who are generally on “the losing side” of support transactions with male partners. This study examines whether equity of dyadic coping is associated with depressive symptoms in adolescent mixed‐gender couples. We disentangle equity of positive and negative dyadic coping, as differential effects might arise.MethodsSelf‐report data on dyadic coping and depressive symptoms were gathered from 124 mixed‐gender couples aged between 16 and 21 years living in Switzerland between 2011 and 2013. Equity of dyadic coping was quantified by calculating the difference between received dyadic coping and provided dyadic coping for each partner separately. These difference scores and the overall level of dyadic coping were used to predict depressive symptoms in both partners using an Actor‐Partner‐Interdependence Model.ResultsFor female adolescents, we found the expected curvilinear association between equity of negative dyadic coping behaviors and depressive symptoms (actor effect). Additionally, the female perception of equity of positive dyadic coping was correlated with less depressive symptoms in male partners (partner effect). For male adolescents, receiving more positive dyadic coping than they provided was associated with more depressive symptoms (actor effect).DiscussionIn female partners, results resembled those in adult mixed‐gender couples. In male partners, results changed depending on the direction of inequity—possibly due to gender role development.
The boosted Hodrick‐Prescott filter is more general than you might think

Published: July 2024

SummaryThe global financial crisis and Covid‐19 recession have renewed discussion concerning trend‐cycle discovery in macroeconomic data, and boosting has recently upgraded the popular Hodrick‐Prescott filter to a modern machine learning device suited to data‐rich and rapid computational environments. This paper extends boosting's trend determination capability to higher order integrated processes and time series with roots that are local to unity. The theory is established by understanding the asymptotic effect of boosting on a simple exponential function. Given a universe of time series in FRED databases that exhibit various dynamic patterns, boosting timely captures downturns at crises and recoveries that follow.

AbstractRadiofrequency (RF) ablation is a minimally invasive therapy for atrial fibrillation. Conventional RF procedures lack intraoperative monitoring of ablation‐induced necrosis, complicating assessment of completeness. While spectroscopic photoacoustic (sPA) imaging shows promise in distinguishing ablated tissue, multi‐spectral imaging is challenging in vivo due to low imaging quality caused by motion. Here, we introduce a cardiac‐gated sPA imaging (CG‐sPA) framework to enhance image quality using a motion‐gated averaging filter, relying on image similarity. Necrotic extent was calculated based on the ratio between spectral unmixed ablated tissue contrast and total tissue contrast, visualizing as a continuous color map to highlight necrotic area. The validation of the concept was conducted in both ex vivo and in vivo swine models. The ablation‐induced necrotic lesion was successfully detected throughout the cardiac cycle through CG‐sPA imaging. The results suggest the CG‐sPA imaging framework has great potential to be incorporated into clinical workflow to guide ablation procedures intraoperatively.

AbstractEarly diagnosis is crucial for effective treatment of socially significant diseases, such as type 1 diabetes mellitus (T1DM), pneumonia, and asthma. This study employs a diagnostic method based on infrared laser spectroscopy of human exhaled breath. The experimental setup comprises a quantum cascade laser, which emits in a pulsed mode with a peak power of up to 150 mW in the spectral range of 5.3–12.8 μm (780–1890 cm−1), and a Herriott multipass gas cell with a specific optical path length of 76 m. Using this setup, spectra of exhaled breath in the mid‐infrared range were obtained from 165 volunteers, including healthy individuals, patients with T1DM, asthma, and pneumonia. The study proposes a hybrid approach for classifying these spectra, utilizing a variational autoencoder for dimensionality reduction and a support vector machine method for classification. The results demonstrate that the proposed hybrid approach outperforms other machine learning method combinations.

Published: July 2024

AbstractObjectivesThis study aimed to investigate the relationship between various independent variables, such as cumulative grade point average (CGPA), socio‐economic backgrounds, anxiety levels, and the self‐rated competency levels, across six domains outlined by the American Dental Education Association (ADEA) of recently graduating dental students during pediatric patient care.MethodsThis cross‐sectional study was conducted at the College of Dentistry, Jouf University, Saudi Arabia. It included 74 participants (37 final‐year dental students and 37 dental interns). Multiple logistic regression was employed to analyze the association between various independent variables (including CGPA, grade point average [GPA] in didactic, practical, and clinical courses, socio‐economic backgrounds, gender, and self‐reported student anxiety) and self‐rated ADEA competency in pediatric dental practice within general dentistry (p < 0.05).ResultsFinal‐year dental students were 28.5 times more likely to be competent in professionalism (C2) than interns (adjusted odds ratio [AOR] = 28.54, p = 0.001). In professionalism (C2), males were 91% less likely to be competent than females (AOR = 0.09, p = 0.001). A high GPA in didactic courses increased the likelihood of competence in health promotion (C4) by 3.4 times compared with an average GPA (AOR = 3.41, p = 0.071). Regarding the establishment and maintenance of oral health (C6B), final‐year dental students were 4.4 times more likely to be competent than interns (AOR = 4.41, p = 0.013).ConclusionThis study identified key factors affecting clinical competency during pediatric patient care among newly graduating dentists. It highlighted the influence of gender differences, academic performance (GPA), and anxiety levels among graduates as significant predictors.

Published: July 2024

AbstractObjectiveTo assess the perceptions of novice and experienced undergraduate dental students of virtual learning with two‐dimensional (2D) and three‐dimensional (3D) vision.Materials and methodsThis qualitative study involved 21 students from the second and fourth years of a 5‐year BDS program. They first performed three operative tasks in virtual reality (VR) training sessions using both 2D and 3D vision. Subsequently, they participated in one of four online focus group discussions (FGDs). The FGDs were recorded and transcribed, and the data obtained from the transcriptions were coded and thematically analyzed.ResultsThree main themes emerged from the focus groups. With regard to their perceptions of 2D and 3D vision, most of the participants preferred 3D over 2D vision, mainly due to an improved ability to perceive depth. With regard to the theme of practicing 3D vision in the VR environment, some participants performed their tasks faster with 3D vision than with 2D vision, while others did not perceive any difference between them. Under the same main theme, some participants experienced headaches and eye fatigue with 3D vision. With regard to their perception of technical aspects, with 3D glasses, the participants experienced unpleasant sensations and saw darker images.ConclusionAll the participants placed greater value on practicing with 3D than with 2D vision in the VR environment. They believed that VR training should be used in the early years of dental education as an adjunct to the phantom head as it helps students acquire the skills needed by dental professionals.
Narrative review on ethical and psychological issues raised by genetic and genomic testing in pediatric oncology care
Authors: Droin‐Mollard Marion , Hervouet Lucile , Lahlou‐Laforêt Khadija , de Montgolfier Sandrine 
Published: July 2024

AbstractIn pediatric oncology, genetic and genomic tests are proposed throughout the care pathway for many reasons (e.g., cancer characterization, identification of the most appropriate treatment, patient selection for clinical trials, identification of tissue/organ donors, or risk of relapse prediction). Despite the many different approaches (somatic or germline testing, targeted gene or genome sequencing), the implicated individuals are confronted with situations that may intersect and that are interesting to compare. No study has identified and analyzed the available works on these new practices in pediatric oncology. The aim of this narrative literature review was to describe the ethical and psychological perspectives of children with cancer, parents, and healthcare professionals when genetic or genomic testing is proposed as part of the cancer management. Eighteen articles met the inclusion criteria and were comprehensively coded using MAXQDA. Their analysis showed that concerning the subjective implications of genetic and genomic testing, the areas of ambivalence (desire of treatment, desire for knowledge, uncertainty, and guilt) reported by patients and their parents seem to mirror the healthcare professionals' concerns. The ethical and psychological issues about predisposition testing, long discussed in the context of hereditary retinoblastoma and Li‐Fraumeni syndrome, represent a useful starting point for a wider discussion of a genetic and genomic testing pathway in pediatric oncology more broadly.

Published: July 2024

AbstractBackgroundHospital at Home (HaH) programs are used throughout the United States and are beneficial in both providing patients care in environments most comfortable to them and freeing up inpatient beds. Better informing patients about HaH programs, while promoting shared decision‐making (SDM), should be prioritized by health systems. SDM apps may promote increased patient agency and understanding of complex HaH care decisions. We previously developed, usability tested, and refined a HaH SDM app.ObjectivesTo evaluate the utility of SDM apps in assisting pneumonia patients with HaH admission.MethodsUsability surveys (N = 16) and semistructured interviews with patients (N = 9) and nurse navigators (N = 3) were utilized to evaluate our app in assisting pneumonia patients as they contemplated HaH admission. Recruitment occurred at three hospitals in the southeastern United States. Surveys were analyzed consistent with their validated measures, while interviews were analyzed using inductive coding methodologies.ResultsPatients supported receiving HaH information via an app, with many noting that presenting content via multiple modalities (e.g., videos, pictures, text) was helpful and that the app assisted their care decision. App‐guided inquiries into patients' care preferences helped patients visualize their priorities and promoted feelings of agency, while providing important information to care teams. Participants found visuals effective at conveying program details, for example, HaH's in‐home setup, which may assist with health literacy challenges. Potential barriers included the need to expand app accessibility for vision impaired and non‐English speaking patients.ConclusionsSDM apps may better inform patients' HaH care decisions, allowing patients self‐directed access to information and engagement with visual content, which may address challenges related to health literacy and navigating complex, time‐sensitive decisions.

Published: July 2024

AbstractIntroductionPerioperative bleeding increases morbidity and mortality in sarcoma patients. Tranexamic acid (TXA), an antifibrinolytic, is widely utilized in non‐sarcoma orthopaedic surgeries, but its adoption in sarcoma surgery is hindered by concerns about thrombotic events.MethodsSearches in Ovid MEDLINE, EMBASE, and CENTRAL were performed without date restrictions. Inclusion criteria encompassed sarcoma patients undergoing surgery with TXA intervention. Two authors independently screened studies, resolved conflicts, and assessed biases.ResultsEight studies met inclusion criteria, comprising 2142 patients. TXA administration varied in dose and timing across studies. Meta‐analysis revealed significantly reduced mean blood loss with TXA of −462.5 mL ([95% confidence interval [CI: −596.7, −328.31], p < 0.001) but no difference in transfusion rates (odds ratio [OR] = 0.51 [95% CI: 0.14–1.89]) or venous thromboembolism events (OR = 0.93 [95% CI: 0.40, 2.16]). Study biases were predominantly moderate to high due to retrospective designs and lack of control for confounders. Quality of reporting varied, with limitations identified in outcome reporting and effect size estimation.ConclusionsDespite evidence of reduced blood loss, the absence of prospective studies limits conclusive recommendations on TXA use in sarcoma surgery. Further research is warranted to determine optimal TXA regimens and assess safety concerns regarding thrombotic events in this patient population.
Exploring the nexus between urban green space and sustainable tourism: Potential for the green economy

Published: July 2024

AbstractThis study explores the nexus between urban green space (UGS) and sustainable tourism (ST) and its potential for achieving a green economy. The Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) approach was applied to reveal the most relevant documents. This study has identified the 35 most relevant documents from the Scopus database. This study reveals a strong nexus between UGS and ST and a strong linkage between various components of UGS and ST. UGS provides several benefits (economic, social, and environmental benefits) in tourism. UGS also promotes tourism in various aspects like environmental, social, and economic aspects. We argue that tourism has become one of the world's most rapidly rising economic industries that promotes a green economy based on UGS with sustainability. The potential challenges of achieving ST and a green economy are lack of proper planning, GHG emissions, maintaining cultural heritage, and poor information systems and communication.
Factors influencing travelers' intention by environmental changes of destination: Cross‐country evidence from Far‐East Asia

Published: July 2024

AbstractTravel intentions are influenced by not only personal background but also external factors such as national disasters, infectious diseases, and government policy. While international flights and the travel market are sharply recovering from the effects of the COVID‐19 pandemic, travel risk will affect future travel demand. This study analyzed the relationship between potential risk of destination and travel avoidance intention using the stimulus‐organism‐response (SOR) model. The survey was conducted with 303 Chinese and 253 South Korean respondents living in countries adjacent to Japan. The results reveal that travel avoidance intentions may be influenced by emotional reactions to the complexity of the geopolitical environment or the diverse protection motivation perceptions of travelers. This study proposes that nationality has a moderate effect on tentative travel avoidance intention compared to gender.
The influence of fear on consumers' experiential consumption preferences during public health crises: Testing multiple mediation models
Authors: Yin Yuan , Zhao Hanxuan , Xu Sihua 
Published: July 2024

AbstractPrevious research showed an association between fear during public health crises and altered consumption behavior, However, the impact of fear on experiential consumption preference remains largely unexplored. This study examined how fear induced by the public health crisis influences individuals' psychological states, cognitive processes, and experiential consumption preferences. A total of 451 respondents from diverse risk cities across China participated in online surveys. The results revealed that: (1) Although COVID‐19 constrained many forms of consumption, fear paradoxically fostered a greater preference for experiential consumption; (2) Fear indirectly affected the preference for experiential consumption through the mediating roles of meaning in life and choice overload; (3) Fear prompted a heightened inclination towards searching for meaning. Notably, the presence of meaning served as the primary mediator in the impact of fear on experiential consumption preference. These findings provide valuable theoretical implications for understanding how fear affects experiential consumption during public health emergencies.
