Acute aortic dissection during minimally invasive cardiac surgery: a case report
Authors: Kumamoto Taisuke 
Published: January 2025

Abstract

Background
Management of acute aortic dissection (AAD) caused by retrograde perfusion through the femoral artery during minimally invasive cardiac surgery (MICS) remains controversial. We present a case of AAD occurring during the late cardiopulmonary bypass (CPB) phase, which was successfully managed by vascular graft replacement, without altering the blood supply route.

Case presentation
A 63-year-old man was scheduled for totally endoscopic aortic valve replacement. CPB was initiated through the right femoral artery and venous cannulation. Approximately 120 min after the initiation of CPB, mean arterial pressure and bilateral cerebral regional oxygen saturation temporarily decreased. Transesophageal echocardiography revealed type A AAD. Cerebral perfusion was preserved, allowing us to proceed to deep hypothermic circulatory arrest and successfully perform ascending aortic replacement without altering the blood supply route.

Conclusions
In MICS, continuous monitoring is crucial as AAD can occur at any point during CPB, and early detection enables successful outcomes.
Mergers Between On-Demand Service Platforms: The Impact on Consumer Surplus and Labor Welfare
Authors: Lin Xiaogang , Lu Tao , Wang Xin , Kou Gang 
Published: January 2025

Practice- and Policy-Oriented Abstract Mergers between on-demand service platforms have recently become prevalent, resulting in antitrust debates. On the one hand, mergers reduce market competition, raising antitrust concerns, such as potential increases in service prices. On the other hand, merged firms typically enable agents to serve all the customers from previously separate platforms, thereby gaining an advantage from resource pooling. To offer guidelines for resolving these debates, we investigate the impact of a merger between two on-demand service platforms. Our results show that because of the merger-enabled pooling benefit and a cross-side network effect (i.e., customers benefit from more agents and vice versa), a merger can result in a win-win-win outcome, where the platform profits, consumer surplus, and labor welfare are all improved after a merger. The win-win-win outcome is more probable if the premerger market is less saturated or if the market is more differentiated on the customer/agent side. Therefore, antitrust agencies might consider being more lenient toward a merger if the market has room to grow or if the two merging platforms have differentiated features.
The I.I.D. Prophet Inequality with Limited Flexibility
Authors: Perez-Salazar Sebastian , Singh Mohit , Toriello Alejandro 
Published: January 2025

In online sales, sellers usually offer each potential buyer a posted price in a take-it-or-leave fashion. Buyers can sometimes see posted prices faced by other buyers, and changing the price frequently could be considered unfair. The literature on posted-price mechanisms and prophet inequality problems has studied the two extremes of pricing policies, the fixed-price policy and fully dynamic pricing. The former is suboptimal in revenue but is perceived as fairer than the latter. This work examines the middle situation, where there are at most k distinct prices over the selling horizon. Using the framework of prophet inequalities with independent and identically distributed random variables, we propose a new prophet inequality for strategies that use at most k thresholds. We present asymptotic results in k and results for small values of k. For k = 2 prices, we show an improvement of at least 11% over the best fixed-price solution. Moreover, k = 5 prices suffice to guarantee almost 99% of the approximation factor obtained by a fully dynamic policy that uses an arbitrary number of prices. From a technical standpoint, we use an infinite-dimensional linear program in our analysis; this formulation could be of independent interest to other online selection problems.

Contract Frames and Supplier Learning
Authors: Zheng Yi , Wang Qiong , Wang Xiaoyan , Yang Zhilin 
Published: January 2025

This research examines the impact of contract framing on supplier learning activities within buyer-supplier relationships, an area previously overshadowed by a focus on internal organizational learning mechanisms. Grounded in regulatory focus theory and organizational learning theory, this study assesses how promotion and prevention contract framing influences suppliers’ exploration and exploitation activities. Survey data from 135 buyer-supplier relationship dyads reveals that promotion and prevention framing distinctly affect suppliers’ learning activities. Specifically, during the duration of the contract, (a) compared with prevention contract framing, promotion contract framing has a stronger positive impact on the supplier’s exploration learning activities; and (b) compared with promotion contract framing, prevention contract framing has a stronger negative impact on the supplier’s exploitation learning activities. This study also reveals how the portfolios and clusters of contract framing influence supplier learning activities. Finally, this study reveals that different learning activities result in varied outcomes for the buyer, with exploration boosting continuity and exploitation improving performance. This contribution broadens the understanding of contract framing’s psychological effects on supplier behavior, offering new insights into the dynamics of organizational learning activities and contract design.

Authors: Maysabila Annisa , Heryanti Rika , Permana Rega , Hasan Zahidah 
Published: January 2025

The problems of shrimp farming with semi-intensive systems are leftover feed, organic matter, and toxic compounds that can reduce water quality. Shrimp pond wastewater treatment can be done through several technologies, such as chemical, physical, and biological treatment. One of biological treatment that widely used for wastewater treatment is bioremediation. Bioremediation is a biological process that utilizes microorganisms to decompose waste in aquaculture ponds into compounds that are not harmful to aquatic biota. Therefore, this research aims to determine the effect of effective microorganism-4 (EM4) in reducing ammonia compounds and BOD levels in shrimp pond wastewater. The research method used is a laboratory-scale experimental method. A total of 6 aquariums were used for 3 different treatments with two replications, control, adding EM4 2.5% and EM4 3% into 5 L of wastewater. The water quality parameters observed were dissolved oxygen, temperature, pH, ammonia, and BOD. The one-way ANOVA test was used in this study. The results showed that there was a decrease in ammonia and BOD levels. The highest reduction of ammonia was found in the treatment with the addition of EM4 2.5%. The decrease in BOD with the highest effectiveness was found in the control treatment (37.73%) with the initial BOD value 5.3 to 3.3. mg/l, which fulfilled the allowed maximum level of standard of Ministerial Decree No. KKP. KEP.28/MEN/2004 concerning General Guidelines for Shrimp Cultivation in Ponds. In conclusion, the small dosage addition of EM4 did not have a significant effect on decreasing levels of ammonia and BOD.

Published: January 2025

Climate change poses significant challenges to traditional feed resources, impacting livestock production and food security. In response, the search for alternative feed resources has gained momentum, aiming to enhance the resilience and sustainability of agriculture in a changing climate. This review explores a diverse array of alternative feed resources that show promise in mitigating the impacts of climate change on feed availability and quality. Drawing from a comprehensive analysis of industry reports, case studies, and articles from sources such as Elsevier, Scopus, PubMed, ScholarOne, PLUS One, Science Direct, and Google Scholar, this study covers a range of innovative options, including insect-based feeds, algae, seaweeds, microbial proteins, residues, by-products, aquatic plants and weeds, hydroponic fodder production, climate-resilient forage crops, agroforestry systems, high-value crop by-products, and silvopastoral systems. Each alternative feed resource is examined in terms of its nutritional value, environmental benefits, and potential challenges to adoption. The review underscores the importance of developing and implementing climate-resilient livestock feeding strategies to ensure food security and sustainability in a changing climate. In light of climate change, this study explores the effects of switching to other feed sources in livestock production. Further research and policy support are emphasized to facilitate the integration of these alternative feed resources into livestock production systems worldwide. By embracing these innovative approaches, the agricultural sector can build resilience, reduce environmental impacts, and secure food supplies amidst climate change challenges through insect-based feeds, hydroponic fodders, agro-industrial byproducts, aquatic plants and algae, among others can be used as substitutes in the era of climate change

Objective
To assess knowledge, attitude, practice, and barriers to skin cancer screening among the general population of the United Arab Emirates (UAE).

Methods
In this cross-sectional study, an online-based questionnaire was distributed via online social media sites such as Facebook, WhatsApp, Twitter, and others to the residents of the UAE. The questionnaire evaluated socio-demographics, knowledge (8 items), attitudes (10 items), practices (14 items), and barriers (9 items) in the context of skin cancer screening. A binary logistic regression was conducted to assess variables associated with practice levels.

Results
The study included 924 participants (51.9% females), with a median (IQR) age of 32 (22–44) years. Results showed a window for knowledge improvement [median = 4 (3–6) out of a maximum potential score of 8], unfavourable attitudes [median = 37 (33–39) out of a maximum potential score of 50], inadequate practices [median = 41 (31–45) out of a maximum possible score of 70]. The most common barriers to skin cancer screening were lack of knowledge about skin cancer (74.1%), lack of awareness of the need for skin cancer screening (72.2%), and absence of symptoms (54.1%). Older age (OR = 0.985, 95%CI: 0.971–0.998) and lack of health insurance (OR = 0.478, 95%CI: 0.301–0.758) were associated with lower screening practices. Female gender (OR = 1.833, 95%CI: 1.361–2.469), being married (OR = 1.415, 95%CI: 1.006–1.992), being a non-smoker (OR = 1.568, 95%CI: 1.045–2.352) or a former smoker (OR = 2.555, 95% CI: 1.082–6.034), and more favourable attitudes (OR = 1.071, 95%CI: 1.044–1.096) were associated with higher screening practices.

Conclusion
The UAE population exhibited moderate knowledge, unfavourable attitudes, and inadequate practices regarding skin cancer screening, with several barriers identified. Targeted online and in-person awareness campaigns are crucial for improving public understanding and attitudes, thereby enhancing screening practices, especially among older adults, males, smokers, and those without health insurance.
A meta-analysis on the impact of concurrent or pre-existing cancer diagnosis on acute myocardial infarction outcomes
Authors: Wang Jie , Yu Jia 
Published: January 2025

Background
There is still a significant gap in understanding the impact of concomitant or previous cancer diagnoses on clinical outcomes of acute myocardial infarction (AMI)

Objective
To provide updated evidence on the effect of concomitant or previous cancer diagnoses on mortality and risk of complications, specifically major bleeding, myocardial reinfarction, and stroke, of patients with AMI.

Methods
A literature search was conducted across PubMed, EMBASE, and Scopus databases. English-language cohort studies published in peer-reviewed journals were included. Pooled effect estimates were calculated using random-effects models and reported as odds ratio (OR) or hazards ratio (HR) with 95% confidence intervals (CI). The certainty of the evidence was assessed using the standard GRADE approach.

Results
A total of 22 studies were included. AMI patients with previous or concurrent cancer had increased risk of in-hospital mortality (OR 1.44, 95% CI: 1.20, 1.73), in-hospital mortality related to cardiovascular complications (OR 2.06, 95% CI: 1.17, 3.65), mortality at 30-days follow up (OR 1.47, 95% CI: 1.24, 1.74) and mortality at 1 year follow up (HR 2.67, 95% CI: 1.73, 4.11), compared to patients without cancer. The risk of major bleeding (OR 1.74, 95% CI: 1.40, 2.16), reinfarction (OR 1.20, 95% CI: 1.05, 1.37), and stroke (OR 1.16, 95% CI: 0.99, 1.37) was also higher in patients with previous or concurrent cancer. The certainty of evidence was rated as "low" for all outcomes, except for the risk of major bleeding, which was rated as "very low."

Conclusion
Based on the low to very low certainty of evidence, we conclude that the presence of previous cancer diagnosis or concurrent cancer may increase the risk of adverse outcomes in patients with AMI. Early interventions, such as close monitoring of cardiac function, lifestyle modifications, and targeted pharmacological therapies, might help mitigate the risk of AMI and improve overall clinical outcomes. However, further methodologically rigorous studies are needed to validate the findings of this review.

Coronary Myocardial Bridge Updates: Anatomy, Pathophysiology, Clinical Manifestations, Diagnosis, and Treatment Options
Authors: Angelini Paolo , Uribe Carlo , Raghuram Arjun 
Published: January 2025

Abstract
Myocardial bridging is a frequent anomaly of the heart in humans and other animals. A myocardial bridge is typically characterized by the systolic narrowing seen with traditional catheter angiography, but this abnormality is not by itself a sign of ischemia or the need for intervention. In particular, transient spontaneous angina must be corroborated by reproducible narrowing during acetylcholine testing; this narrowing occurs during resting conditions and is responsive to nitroglycerin administration. Ischemia in myocardial bridging can result from acquired arterial wall disease (coronary artery atherosclerotic disease) or from instances of coronary spasm. Clinical evaluation should seek to identify baseline features such as myocardial bridge thickness (by using computerized axial tomography or intravascular ultrasonography) and the severity of systolic compression or reproducible spasticity (by administering acetylcholine). Nuclear myocardial scintigraphy is usually negative in patients with isolated myocardial bridging. Spastic coronary hyperactivity must be treated initially with antispasmodic medications, such as calcium channel blockers and nitrates, rather than by percutaneous stent placement or bypass surgery. Only exceptionally prolonged and critically severe spasm can induce intraluminal clotting and acute myocardial infarction. Recognizing the exceptionality and variability of ischemic presentations related to myocardial bridging is essential, as is establishing appropriate investigational methods for each of these facets of the condition.
Targeted maximum likelihood based estimation for longitudinal mediation analysis
Authors: Wang Zeyi , Laan Lars van der , Petersen Maya , Gerds Thomas , Kvist Kajsa , Laan Mark van der 
Published: January 2025

Abstract
Causal mediation analysis with random interventions has become an area of significant interest for understanding time-varying effects with longitudinal and survival outcomes. To tackle causal and statistical challenges due to the complex longitudinal data structure with time-varying confounders, competing risks, and informative censoring, there exists a general desire to combine machine learning techniques and semiparametric theory. In this article, we focus on targeted maximum likelihood estimation (TMLE) of longitudinal natural direct and indirect effects defined with random interventions. The proposed estimators are multiply robust, locally efficient, and directly estimate and update the conditional densities that factorize data likelihoods. We utilize the highly adaptive lasso (HAL) and projection representations to derive new estimators (HAL-EIC) of the efficient influence curves (EICs) of longitudinal mediation problems and propose a fast one-step TMLE algorithm using HAL-EIC while preserving the asymptotic properties. The proposed method can be generalized for other longitudinal causal parameters that are smooth functions of data likelihoods, and thereby provides a novel and flexible statistical toolbox.
A multimodal discourse analysis of the music video ‘IBA’
Authors: Oyebamiji Grace A. , Olutayo Grace O. 
Published: January 2025

Abstract
This study presents a comprehensive multimodal analysis of the music video ‘Iba,’ offering an in-depth exploration of the meaning and communication conveyed through this captivating audio-visual performance. The central research question guiding this investigation is: How do the diverse semiotic resources, including audio, visuals, lyrics, gestures, and symbolic representations, converge within the music video to construct its overarching message and aesthetic appeal? Employing Kress’ robust theoretical framework of social semiotic theory of multimodality, this research critically examines the video’s semiotic materials and their interconnections. The analysis demonstrates that ‘Iba’ skilfully deploys a vast array of semiotic modalities to express a profound narrative and cultural significance. This study underscores the remarkable potency of social semiotic multimodal analysis in illuminating music videos as a formidable medium for artistic expression and cultural preservation. The findings contribute to a deeper understanding of how multimodal ensembles can be strategically leveraged to convey complex meanings and evoke powerful responses from the audience. This research holds important implications for scholars interested in the intersections of music, visual culture, and meaning-making.
The Temporal organization of learned vocal behavior is predicted by species rather than experience
Authors: Edwards Jacob Aaron , Rivera Moises , Woolley Sarah Margaret Nicolay 
Published: January 2025

Birdsong is hierarchically organized in time, like speech and other communication behaviors. Syllables are produced in sequences to form song motifs and bouts. While syllables are copied from tutors, the factors that determine song temporal organization, including syllable sequencing (syntax), are unknown. Here, we tested the roles of learning and species genetics in song organization. We manipulated juvenile song experience and genetics in three species of estrildid finches (zebra finches:Taeniopygia guttata castanotis; long-tailed finches:Poephila acuticauda; Bengalese finches:Lonchura striatavar.domestica). We analyzed the adult songs of male birds that were: 1) tutored by conspecifics; 2) untutored; 3) tutored by heterospecifics; and 4) genetic hybrids. Song macrostructure, syllable sequencing, and syllable timing were quantified and compared within and across species. Results showed that song organization was consistent within a species and differed across species, regardless of experience. Temporal features did not differ between tutored and untutored birds of the same species. The songs of birds tutored by other species were composed of heterospecific syllables produced in sequences typical of conspecific song. The songs of genetic hybrids showed the organization of both parental species, despite the fact that only males sing. Results indicate that song organization is predicted by species rather than experience.Significance statementLike speech, birdsong is a complex and learned behavior that is hierarchically organized in time. Previous work suggests that species identity influences song temporal organization. We tested the roles of genetics and learning in song organization in three songbird species and genetic hybrids. Birds were either tutored, untutored, or tutored by another species. Results showed that song organization was consistent within a species and differed across species, regardless of experience. Our findings suggest that the organization of behavioral sequences is shaped by both genes and experience, with the influence of experience acting at the level of units in a sequence and the influence of species genetics acting at the level of sequence organization.
Successful treatment of a therapy-resistant, giant liver hemangioma with repeated bleomycin TACE: A case report

Published: January 2025

AbstractWe report a case of a female patient in her 40s who presented with right upper quadrant pain and abdominal discomfort. Surgical removal was not possible due to the location of the lesion. Between 2021 and 2022, the patient had four additional sessions of conventional transarterial embolization (TAE) with Lipiodol, but none succeeded in sufficiently reducing the hemangioma's size or permanently improving the symptoms. In November 2022, we used transarterial chemoembolization (TACE) with a Bleomycin-Lipiodol emulsion. Follow-up MRI scans showed a gradual reduction in the hemangioma volume, but the symptoms only improved partially. Hence, the patient underwent a second bleomycin TACE embolization in November 2023. By August 2024, control showed a total volume reduction of 409 cm³ (56%) and significant symptom improvement. This case demonstrates that Bleomycin-Lipiodol TACE can effectively reduce the size of giant liver hemangiomas, even after the failure of other interventional therapies.
