P1.045. Management of a Large Esophagojejunostomy Defect After Laparoscopic Total Gastrectomy Using Endoscopic Vacuum Therapy and Adjunctive Stenting

Abstract Topic Benign Disease: Other Background Esophagojejunostomy (EJ) leakage after total gastrectomy remains a life-threatening complication. While endoscopic vacuum therapy (EVT) has emerged as an effective treatment option, management of large anastomotic disruption and sub...

Impact of a prolonged nationwide residents’ strike on acute ischemic stroke care in a metropolitan city

Abstract BackgroundAcute ischemic stroke (AIS) requires timely management in both prehospital and in-hospital phases to optimize outcomes. In 2024, South Korea experienced a prolonged nationwide residents’ strike that disrupted the healthcare system, potentially affecting AIS man...

Urinary Extracellular Vesicles as a Source of Biomarkers for Kidney Allograft Rejection: A Systematic Review

BACKGROUND: Kidney transplant rejection remains a leading cause of graft loss, and diagnosis still depends largely on invasive biopsies. Urinary extracellular vesicles (uEVs) offer a potential noninvasive alternative for detecting allograft rejection through molecular profiling o...

Determining the optimal design characteristics of trapezoidal piano key weirs for improved water discharge

Abstract This study attempts to evaluate the influence of design factors and flow characteristics on the discharge capacity of trapezoidal piano key weirs. To evaluate the influence of the main design factors on discharge rates, 9 models were simulated, with width ratios of 1.25,...

Myoglianin coordinates hormonal and nutrient signaling to control metamorphosis and tissue growth in the fall armyworm

The transition from larval to pupal stage in holometabolous insects is a critical developmental decision regulated by hormonal and nutritional cues. The studies reported here revealed a central role for the TGF-β ligand Myoglianin (Myo) in integrating these signals in a major lep...

Moment Matching for Bayesian Inference in the Baseline New Keynesian Model

Abstract The sparsity and small size of economic samples often obscure the identification of parameters in macroeconomic models. These identification problems originate from the poorly defined mapping between a structural model and reduced-form parameters. Hence, researchers rely...

Photoacoustic Tomography with Time-Dependent Damping: Theoretical and a Convolutional Neural Network-Guided Numerical Inversion Procedure

Abstract. In photoacoustic tomography (PAT), a hybrid imaging modality that is based on the acoustic detection of optical absorption from biological tissue exposed to a pulsed laser, a short pulse laser generates an initial pressure proportional to the absorbed optical energy, wh...

Influence of many-body correlation and mixed-valence fluctuations on X-ray magnetic circular dichroism and resonant inelastic X-ray scattering spectra

X-ray magnetic circular dichroism (XMCD) and resonant inelastic X-ray scattering with magnetic circular dichroism (RIXS-MCD) provide unparalleled insights into the electronic and magnetic dynamics of complex materials. However, interpreting their spectra in mixed-valence systems...

Optimal control strategies for dengue transmission under varying adult prevalence of Wolbachia -carrying mosquitoes: a deterministic mathematical modeling study

Objectives: This study aimed to develop prevalence-informed post-release dengue control strategies for settings in which Wolbachia-carrying Aedes aegypti mosquitoes have become established through population replacement and to quantify how optimal supplementary intervention inten...

Age-Stratified Outcomes of Off-Clamp Robot-Assisted Partial Nephrectomy: A Comparison of Patients Younger Than 65 Years and Those Aged 65 Years or Older

Background: Evidence for completely off-clamp robot-assisted partial nephrectomy (RAPN) in older patients is limited. We compared age-stratified short-term outcomes. Methods: We reviewed 146 consecutive patients who underwent off-clamp RAPN between June 2022 and March 2026: 99 we...

Clinical Characteristics and Outcomes of Pediatric Patients With Long QT Syndrome: A Korean Multicenter Cohort Study

This multicenter nationwide cohort study comprehensively analyzed the clinical features, genetic architecture, and outcomes of Korean pediatric patients with long QT syndrome (LQTS).Prolonged QT intervals, fetal arrhythmia, and LQT2/3 genotypes compared to LQT1 were independent r...

Effect of visual stimulation on quantitative light-touch assessment using the active von Frey filament test

Quantitative assessment of light-touch sensation is essential in the evaluation of peripheral nerve disorders. Although the active von Frey filament test (AvF) provides objective and continuous tactile threshold measurements, the influence of testing conditions on AvF values rema...

A survey of deep multivariate time-series models with an empirical reproducibility audit

Multivariate time series (MTS) analysis is increasingly important for extracting insights from complex, interdependent temporal data in domains such as healthcare, finance, and industrial monitoring. Recent advances in deep learning have significantly improved MTS modeling; yet,...

Global spatiotemporal variability of chlorophyll a and environmental drivers revealed by empirical orthogonal function analysis

Abstract Chlorophyll a (Chl a ) is a key indicator of phytoplankton biomass and marine primary productivity, linking ocean ecosystem change to biogeochemical cycling and climate. Understanding the environmental controls on long‐term Chl a variability is therefore essential. Here,...

In-Situ anchoring of amorphous NixB nanoparticles onto Nb2CTx MXene nanosheets for high-performance asymmetric supercapacitors

An amorphous nickel boride/niobium carbide MXene (Ni x B/Nb 2 CT x ) composite was designed and synthesized via a combined HF-assisted etching and in-situ chemical reduction strategy. The uniform anchoring of 0D Ni x B nanoparticles within the multilayered Nb 2 CT x nanosheets le...

Optimization of Poly-γ-Glutamic Acid Production by Moderate Electric Field-Assisted Fermentation in a Haematococcus pluvialis-Based Medium

Moderate electric field (MEF) fermentation was investigated as a nonthermal stress strategy to enhance the formation of extracellular polymeric substances (EPS; mucilage) by Bacillus subtilis HA in a Haematococcus-based medium. Response surface methodology (RSM), combined with a...

Brachyspira hyodysenteriae detected in a dog with acute haemorrhagic diarrhoea: a case report

Abstract Background Brachyspira hyodysenteriae is a well-known pathogen of swine dysentery, a severe mucohaemorrhagic colitis in pigs. While several Brachyspira species are reported in dogs, natural Brachyspira hyodysenteriae detection in dogs is extremely rare. This case report...

Halophyte-derived bacterial SynComs improve soybean growth under salinity stress

Abstract Rhizosphere microbes with plant growth-promoting (PGP) traits can sustain crop productivity, yet endophyte-derived synthetic communities (SynComs) from hypersaline environments remain underexplored. We hypothesize that halophyte endophyte-derived SynComs improve stress t...

Enhanced salivary correlation between Streptococcus mutans and herpes simplex virus-1 in oral squamous cell carcinoma: a case-control study

Streptococcus mutans modulates local immune responses in the oral mucosa and has been implicated in oral squamous cell carcinoma (OSCC) pathogenesis. Emerging evidence suggests that certain oral bacteria can influence viral infections through immune modulation. This case-control...
