Abstract
The nitrogen isotopic composition (δ
15N) of amino acids can be used to estimate the trophic position of organisms with high precision compared to bulk tissue analyses, and shed light on potential food sources and food webs. Sagami Bay, Japan, is located at the tectonic plate boundary and have complex bottom topography, making multiple sources of organic matter to bathyal deep-sea ecosystems. Here, we applied this method to benthic animals (meiofauna, macrofauna, and megafauna) living at 1430 m deep in the central Sagami Bay, Japan. The δ
15N value of phenylalanine (δ
15NPhe) reflects the value of primary producers and was used to estimate the food sources of organisms, while the difference between δ
15N value of glutamic acid (δ
15NGlu) and δ
15NPhe shifts between food source and consumer and was thus used to estimate the trophic position (TPGlu/Phe). The data obtained were interpreted together with previously reported values from benthic foraminifera of the same site for a holistic understanding of the food web. The trophic positions of organisms from the central Sagami Bay ranged mostly from 2.2 to 3.6, except hydrozoans (up to 4.3). Organisms with similar bulk tissue δ
15N values sometimes exhibited different TPGlu/Phe values. The observed δ15NPhe varied greatly among benthic organisms in the central Sagami Bay (− 8.3‰ to 21.1‰), suggesting a wide variety of food sources exhibiting different δ15NPhe values. Given the location of the study site at the central part of the deep basin, various organic matter from terrestrial, planktic, coastal, upper bathyal, and perhaps chemosynthetic origins can be expected to accumulate and become available for bathyal benthic organisms. Furthermore, the cross-plot of δ15NPhe values and bulk tissue δ
13C values, another indicator of food source, suggested that macro–megafauna examined rely on different organic matter than metazoan meiofauna and foraminifera, which rely on particulate organic matter and bulk sediments. Despite living in the same habitat, organisms of these two size classes may belong to independent food webs due to differences in feeding ecology.
Comparative study on the drying mechanisms and characteristic changes of fabrics according to heat transfer principles
Authors: Lee Jiyul , Cho Jaeyong , Lee Suhyun 
Published: January 2025

Abstract
Microwave-convection (MWC) drying was compared with hot air-convection (HAC) drying to elucidate the differences in the drying characteristics of fabrics based on the moisture type and drying performance. For a single fabric, free water removal was more effective with MWC drying, whereas HAC drying was better suited for bound water removal. For stacked fabrics, the moisture leveling effect of MWC drying enabled a uniform drying of the fabric, evaporating both free water and bound water. The dimensional change of MWC was lower than that of HAC, and the toughness and fiber morphology of the fabrics dried using MWC were comparable to those of untreated fabrics. Furthermore, MWC drying exhibited a higher energy efficiency with increasing fabric loads. The lower drying performance of HAC drying was attributed to the convection of hot air and the limitation of heat conduction. The findings of this study are expected to help develop automatic drying algorithms for household dryers.

Abstract

Objectives
To translate, cross-culturally adapt and validate the Serbian Ankylosing Spondylitis Quality of Life (ASQoL) questionnaire, e.g. according to the new nomenclature Radiographic-Axial Spondyloarthritis (r-axSpA), and to relate it to disease activity and functional status domains.

Methods
Four stages were accomplished: (1) Bilingual and lay panel for translation and cross-cultural adaptation (2) Cognitive debriefing interviews (assessing the language and cultural equivalence of the concepts used in the Serbian ASQoL translation) for face and content validity (3) Psychometric evaluation: (a) convergent validity by NHP as a comparator scale and (b) known group validity by correlations with disease activity and overall health status and reliability (internal consistency and test-retest reliability) (4) Independent regression analyses for relations between ASQoL and ASDAS, BASDAI, BASFI, Schober’s test, respiratory index and SPARCC were used. The statistical program SPSS (version 21; IBM, Armonk, NY, USA) was used.

Results
The bilingual panel made a unified version of the translated documents, a lay panel confirmed the clarity of the questionnaire. Cognitive debriefing interviews with 10 patients evaluated the Serbian ASQoL as clear, precise, easy to complete. The psychometric properties with 60 randomly selected patients showed good convergent validity between ASQoL and NHP domains of pain (r = 0.79), emotional reactions (r = 0.78), physical activity (r = 0.77) and energy (r = 0.75). The internal reliability was 0.95 and 0.91 (1st and 2nd administration), respectively, and the test-retest reliability was 0.84. Regression analyses showed highly significant relationships (p < 0.001) between ASQoL and ASDAS (R²=0.403), BASDAI (R²=0.564) and BASFI (R²=0.444).

Conclusion
The Serbian ASQoL demonstrated good psychometric properties and significant relationships with disease activity and functional status and is recommended for quality of life assessment in Serbian-speaking ankylosing spondylitis (radiographic axial spondyloarthritis) patients, both in clinical practice and clinical research.

Published: January 2025

Abstract

Background
The treatment landscape for intracranial aneurysms (IAs), particularly those involving the middle cerebral artery (MCA), has evolved significantly over the past two decades. The pivotal International Subarachnoid Aneurysm Trial (ISAT) of 2002 heralded a paradigm shift toward endovascular coiling as the preferred treatment modality for ruptured IAs, prompting a widespread adoption of this approach in neurosurgical centers worldwide. However, despite the initial enthusiasm for coiling, microsurgical clipping remains the cornerstone of treatment for MCA aneurysms in experienced cerebrovascular centers due to its superior efficacy in achieving complete aneurysm occlusion and minimizing long-term recurrence rates.

Objective
We aimed to compare the effectiveness and safety of microsurgical clipping versus endovascular coiling for middle cerebral artery (MCA) aneurysms, focusing on rates of occlusion, procedural complications, and long-term neurological outcomes.

Methods
We prospectively analyzed 40 patients with ruptured and unruptured MCA aneurysms presented at Ain Shams University Hospital neurosurgical department from January 2021 to December 2023 and they underwent microsurgical clipping or endovascular coiling.

Results
In patients treated with microsurgical clipping for MCA aneurysms, commonly associated with hypertension, smoking, and drug abuse, favorable clinical grades were observed, with most aneurysms located at bifurcations. Intra-operative complications, primarily premature rupture, led to a 12.45-day hospital stay, with post-operative issues including vasospasm-related strokes and infections. Six-month follow-up showed a 65% favorable outcome. Conversely, in 20 patients treated with endovascular coiling, typically for ruptured aneurysms, hypertension, and smoking were prevalent risk factors, with fewer complications during hospitalization (average 4.2 days). At 6-month and 1-year follow-ups, complete occlusion rates were 85% and 80%, respectively, with some cases requiring further intervention due to incomplete occlusion.

Conclusion
While endovascular coiling has revolutionized the management of intracranial aneurysms, surgical clipping remains a vital treatment option, offering superior outcomes in select cases, particularly those involving MCA aneurysms. A balanced approach, tailored to individual patient characteristics and institutional expertise, is essential to optimize treatment outcomes and minimize the risk of recurrence and re-rupture in this challenging patient population.

Abstract

Background
Acute myocardial infarction during pregnancy is a rare condition with an incidence of 1 to 10 per 100,000 deliveries. ST-elevation myocardial infarction (STEMI) is dominating the clinical presentation. It is estimated that 29% of the patients had normal coronary arteries, and hyperthyroidism may be associated with coronary vasospasm.

Case Presentation: A 30-year-old pregnant woman was referred with inferior STEMI post-failed fibrinolytic therapy. Her hospitalization course was complicated by non-sustained ventricular tachycardia and cardiogenic shock. Coronary angiography revealed normal coronary arteries without intracoronary thrombus, coronary dissection, or coronary atherosclerotic lesion. Laboratory test showed high Free T4 2.71 ng/dL and low TSH < 0.05 mlU/mL. Patient’s condition and hospitalization course were significantly improved after the initiation of hyperthyroid therapy. We suspected a hyperthyroid-induced coronary vasospasm as a potential etiology of myocardial infarction with non-obstructive coronary artery (MINOCA) in this patient.

Conclusion
Although MINOCA due to hyperthyroidism is a rare finding among pregnant young woman, recognizing this etiology is a paramount of importance due to improved survival with appropriate and specific therapy.
Anthropomorphism in artificial intelligence: a game-changer for brand marketing
Authors: Gomes Sofia , Lopes João M. , Nogueira Elisabete 
Published: January 2025

Abstract
The expansion of brands adopting artificial intelligence services with human characteristics, such as chatbots, has revolutionized digital marketing strategies, transforming how companies reach and engage customers. This technological innovation is reshaping digital interactions between companies and consumers, offering a more personalized and efficient experience. This study explores the influence of chatbot anthropomorphism on customer engagement and purchasing decision-making with brands that use this artificial intelligence service. Data from a questionnaire with 1319 participants was analyzed using partial least squares method. Chatbot anthropomorphism has a more positive influence on purchasing decision-making when this relationship is mediated by customer engagement. In turn, customer involvement also has a positive influence on decision-making. The results emphasize that for a greater influence of the chatbot's anthropomorphism on purchasing decision-making, the customer must first be engaged with the chatbot. This research illuminates a new path in the domain of AI-enabled brand interactions, showing the distinct influence of anthropomorphism in chatbots on customer satisfaction, trust and loyalty, thus revolutionizing traditional paradigms of consumer-brand engagement and decision-making processes. By exploring the intricate dynamics between customer engagement with anthropomorphized chatbots and purchasing decisions, this study breaks new ground, offering unprecedented insight into the transformative potential of human-like chatbot interactions in shaping consumer behavior and brand relationships.

Published: January 2025

Abstract

Background
Keloid is a fibro-proliferative dermal benign growth affecting the Asian population. In India, ear keloids are common, often resulting from ear piercing, a prevalent cultural practice. The resultant ear keloids pose aesthetic concerns, leading to significant psychological distress, and necessitating effective treatment. While various treatment options are available, their outcomes and recurrence rates vary, highlighting the need for individualized and optimal management strategies. Our study aimed to observe the combined effect of intralesional triamcinolone with hyaluronidase on keloid regression.

Methods
This prospective observational study was conducted at our tertiary care institute over 1 and a half years. Fifty patients who met the inclusion criteria were enrolled and received intralesional triamcinolone injection with hyaluronidase. Keloid regression was assessed using the Vancouver Scar Scale (VSS), while the visual analogue score (VAS) and patient satisfaction score (PSS) provided subjective evaluations of symptom relief. All patients underwent compression therapy. Patients were evaluated at every visit and then at 1 year for symptom relief, keloid regression, and complications if any.

Results
Demographic data of all patients were recorded. Ear keloids were predominantly observed in females, with a male-to-female ratio of 18:32. The most common etiology was trauma following ear piercing, accounting for 46% of cases. All patients showed improvement in VSS, VAS, and PSS scores in the follow-up visits. A total of 98% of patients demonstrated a complete treatment response, with only a single instance of recurrence.

Conclusion
Intralesional triamcinolone with hyaluronidase provides satisfactory symptomatic relief and has lower recurrence rates. All patients showed improvement in the Vancouver Scar Scale and had enhanced VAS and PSS scores.
Inter-event time power laws in heterogeneous systems
Authors: Ettori F. , Sluckin T. J. , Biscari P. 
Published: January 2025

Abstract
We investigate the dynamic behavior of spin reversal events in the dilute Ising model, focusing on the influence of static disorder introduced by pinned spins. Our Monte Carlo simulations reveal that in a homogeneous, defect-free system, the inter-event time (IET) between local spin flips follows an exponential distribution, characteristic of Poissonian processes. However, in heterogeneous systems where defects are present, we observe a significant departure from this behavior. At high temperatures, the IET exhibits a power-law distribution resulting from the interplay of spins located in varying potential environments, where defect density influences reversal probabilities. At low temperatures, all site classes converge to a unique power-law distribution, regardless of their potential, leading to distinct critical exponents for the high- and low-temperature regimes. This transition from exponential to power-law behavior underscores the critical response features of magnetic systems with defects, suggesting analogies to glassy dynamics. Our findings highlight the complex mechanisms governing spin dynamics in disordered systems, with implications for understanding the universal aspects of relaxation in glassy materials.

Abstract

Context
Glycemic outcomes in youth with type 1 diabetes (T1D) in the United States using the 2 most common automated insulin delivery (AID) systems, Insulet Omnipod 5 (OP5) and Tandem Control IQ (CIQ), have not been compared.

Objective
We performed the first head-to-head analysis of changes in glycemic metrics among youth initiating AID.

Methods
This single-center, retrospective study included youth &lt; 21 years with T1D, who started OP5 or CIQ between January 2020 and December 2023, and had ≥ 70% continuous glucose monitoring (CGM) active time. We obtained 14-day baseline and 90-day CGM and AID data. A multiple linear regression model assessed for changes in 90-day time in range (TIR) according to AID system, adjusting for covariates. Subanalyses were conducted according to baseline TIR categories.

Results
Among the 428 included youth, there were 214 (50%) in each AID group. OP5 users had a shorter T1D duration (1.6 vs 5.5 years, P &lt; .001) and were more likely to have transitioned from multiple daily injections (76.1% vs 20.1%, P &lt; .001). Baseline TIR was similar between groups (OP5 51.6% vs CIQ 53.1%, P = .70). 90-day TIR increased in both groups (P &lt; .001), rising by 11.8 percentage points (95% CI [10.4, 13.3]) in OP5 users and 9.8 percentage points (95% CI [8.3, 11.2]) in CIQ users, without any significant between-group differences (P = .08). There were no between-group differences in 90-day TIR according to categorical baseline TIR.

Conclusion
There are no clinically significant differences in 90-day TIR among youth with T1D initiating the 2 most commonly used AID systems. Patient preference and shared decision making should continue to guide the selection of AID systems.
Pros and Cons of Inpatient SGLT2i Use for Hyperglycemia and Heart Failure
Authors: Fried Hayley , Harris Yael Tobi , Schulman-Rosenbaum Rifka 
Published: January 2025

Abstract
Sodium-glucose cotransporter 2 inhibitors (SGLT2is), originally approved by the US Food and Drug Administration for glycemic control in type 2 diabetes mellitus (DM2), have shown substantial cardiovascular and renal benefits, leading to their expanded use in managing heart failure (HF) and chronic kidney disease in the outpatient setting. Despite these benefits, their use for inpatient hyperglycemia management is not universally endorsed due to safety concerns and inadequate data. However, emerging evidence suggests potential advantages of initiating SGLT2i treatment for patients during hospitalization in the setting of HF. While SGLT2is are not recommended for managing inpatient hyperglycemia, initiation during hospitalization for HF provides significant benefits. We review the current literature on the pros and cons of using SGLT2is in hospitalized DM2 and HF patients and provide guidance on careful patient selection and risk mitigation for inpatient use.
Horace Walpole, the Prince, and the Baron
Authors: Guthrie Neil 
Published: January 2025

Abstract
The precise nature of Horace Walpole's sexuality remains elusive, in spite of the extent of his surviving correspondence — which is vast but with notable and possibly strategic gaps. Walpole's reactions to two queer men he encountered in Italy, Cardinal Prince Henry Benedict and Baron Philipp von Stosch, nevertheless reveal some of his preoccupations and anxieties in relation to male-male sexual desire.
The Dynamics of Authorial Forgetting: The Case of James Robertson
Authors: Walker Robert G. 
Published: January 2025

Abstract
James Robertson (1713 – 95) was born in Dublin but spent most of his life in England. By profession a comic actor associated for two decades with the York Theatre, in 1770 he published anonymously a relatively large volume of poetry (239 pages), with the title Poems, Consisting of Tales, Fables, Epigrams, &c. &c. By Nobody. His attribution of his poetry to Nobody was playful, but, in an irony of history, it has turned out to be prophetic. Despite the relative success of this volume — it went through three additional editions in his lifetime — and despite a surprising amount of contemporary recognition both as a player and as a poet, he has now totally disappeared from literary history. I suggest how and why he lost his place in the canon and what value there is in reading his work today, especially as a signpost of the relative persistence of Augustan satire (Pope, Swift, and others) beyond the death of Pope in 1744.
Adjacency spectrum and Wiener index of essential ideal graph of a finite commutative ring
Authors: Jamsheena Panikkara , Chithra Velu , Subarsha Banerjee  
Published: January 2025

Let R be a commutative ring with unity. The essential ideal graph ER of R, is a graph with a vertex set consisting of all nonzero proper ideals of R and two vertices I and K are adjacent if and only if I + K is an essential ideal. In this paper, we study the adjacency spectrum of the essential ideal graph of the finite commutative ring Zn, for n = {pm, pm1qm2}, where p, q are distinct primes, and m, m1 , m2 ε N. We show that 0 is an eigenvalue of the adjacency matrix of EZn if and only if either n = p2 or n is not a product of distinct primes. We also determine all the eigenvalues of the adjacency matrix of EZn whenever n is a product of three or four distinct primes. Moreover, we calculate the topological indices, namely the Wiener index and hyper-Wiener index of the essential ideal graph of Zn, for different forms of n.
Relationship between nocturnal blood pressure dip and β-parapapillary atrophy zone choroidal vessel density in normal-tension glaucoma patients
Authors: Park Jimin , Song Woo Keun , Baek Min Su , Yoon Jooyoung , Lee Anna , Kim Ko Eun , Kook Michael S. 
Published: January 2025

Purpose
To investigate the relationship between nocturnal blood pressure (BP) dip and parapapillary choroidal vessel density (pCVD) in patients with normal-tension glaucoma (NTG)

Methods
This study analyzed 267 eyes of 267 untreated NTG patients who underwent 24-hour (h) intraocular pressure (IOP) and ambulatory BP monitoring in the habitual position. Patients were classified into 3 groups [non-dippers (nocturnal BP dip < 10%), dippers (nocturnal BP dip between 10% and 20%, and over-dippers (nocturnal BP dip > 20%)], and pCVDs were measured by using optical coherence tomography angiography (OCTA) images. Logistic regression analyses were performed to identify clinical factors associated with “over-dipper” cases. Linear regression analyses were conducted to determine the correlation between various clinical variables and pCVD.

Results
In clinical characteristics, over-dippers exhibited lower pCVD values compared to non-dippers or dippers (P = 0.004). High diurnal intraocular pressure (IOP) fluctuation (P = 0.031), high diurnal mean arterial pressure (MAP) fluctuation (P = 0.001), and low pCVD (P = 0.002) were identified as predictors of being “over-dipper” in multivariable logistic regression analyses. Moreover, peripapillary retinal vessel density (P = 0.040), presence of choroidal microvasculature dropout (P = 0.039), and nocturnal MAP dip % (P = 0.002) showed significant correlations with pCVD according to multivariable linear regression analyses.

Conclusion
Over-dippers presented with lower pCVD than non-dippers or dippers as measured by OCTA choroidal images. Low pCVD was a predictor of “over-dipper” cases and associated with a greater percentage of nocturnal MAP dip in NTG patients. 24-h ambulatory BP monitoring may provide further information for detecting low pCVD in NTG patients with nocturnal BP dip.
