Immediate versus staged complete revascularisation during index admission in patients with ST-segment elevation myocardial infarction and multivessel disease (OPTION-STEMI): a multicentre, non-inferiority, open-label, randomised trial.

Background: The optimal timing of complete revascularisation for patients with ST-segment elevation myocardial infarction (STEMI) and multivessel coronary artery disease remains unclear. We aimed to assess whether immediate complete revascularisation was non-inferior to staged complete revascularisation during the index admission.

Methods: We conducted an open-label, randomised, non-inferiority trial at 14 hospitals in South Korea.

Efficacy of intraoperative low-dose remimazolam as a third antiemetic agent for preventing early postoperative nausea in high-risk patient: A Randomized controlled trial.

Background: Postoperative nausea and vomiting (PONV) is one of the most common and distressing side effects of general anesthesia. According to the Fourth Consensus Guidelines for the Management of Postoperative Nausea and Vomiting, patients at high risk of PONV should be given at least three prophylactic antiemetic agents. As previous studies have reported antiemetic effects of sub-hypnotic doses of midazolam, a benzodiazepine, we investigated the efficacy of remimazolam, an ultra-short-acting benzodiazepine, as a third prophylactic antiemetic agent when administered at a low target dose.

Clinical Relevance of Fractional Flow Reserve-Guided Percutaneous Coronary Interevention According to Left Ventricular Ejection Fraction in Patients With Acute Myocardial Infarction and Multivessel Disease.

Background: Fractional flow reserve (FFR)-guided or angiography-guided complete revascularization has not been evaluated in patients with acute myocardial infarction (AMI) with multivessel disease and reduced left ventricular ejection fraction (LVEF).

Targeting the Glucose-Insulin Link in Head and Neck Squamous Cell Carcinoma Induces Cytotoxic Oxidative Stress and Inhibits Cancer Growth.

Unlabelled: Head and neck squamous cell carcinoma (HNSCC) remains a clinically challenging malignancy with limited targeted therapy options and poor patient outcomes. Thus, identifying unique dependencies, including HNSCC-specific metabolic reprogramming, is imperative for improving treatment strategies for this disease. In this study, we show that HNSCC relies on elevated glucose transporter 1 (GLUT1)-mediated glucose uptake to support redox homeostasis and tumor growth.

Deep learning-based classification of diffusion-weighted imaging-fluid-attenuated inversion recovery mismatch.

The presence of a diffusion-weighted imaging (DWI)-fluid-attenuated inversion recovery (FLAIR) mismatch holds potential value in identifying candidates for recanalization treatment. However, the visual assessment of DWI-FLAIR mismatch is subject to limitations due to variability among raters, which affects accuracy and consistency. To overcome these challenges, we aimed to develop and validate a deep learning-based classifier to categorize the mismatch.

Early left ventricular unloading after venoarterial extracorporeal membrane oxygenation: 1-year outcomes of the EARLY-UNLOAD randomized clinical trial.

Aims: The long-term effects of early left ventricular (LV) unloading after venoarterial extracorporeal membrane oxygenation (VA-ECMO) remain unclear.

Methods And Results: The EARLY-UNLOAD trial was a single-centre, investigator-initiated, open-label, randomized clinical trial involving 116 patients with cardiogenic shock (CS) undergoing VA-ECMO. The patients were randomly assigned to undergo either early routine LV unloading by transseptal left atrial cannulation within 12 h after randomization or the conventional approach, which permitted rescue transseptal cannulation in case of an increased LV afterload.

CRISPR activation identifies a novel miR-2861 binding site that facilitates the osteogenesis of human mesenchymal stem cells.

We investigated the regulation of histone deacetylases (HDACs) by miR-2861 in the osteoblastic differentiation of human mesenchymal stem cells (MSCs) and miR-2861 binding site by CRISPR activation (CRISPRa). Transfection of miR-2861 into human MSCs was performed and the effect on osteoblast differentiation was analyzed. Using catalytically inactive Cas12a, the CRISPRa system induced targeted overexpression of endogenous miRNA and repressed the luciferase activities of reporters that contained functional miRNA target sites.

Functional Connectivity Alterations in Patients with Post-stroke Epilepsy Based on Source-level EEG and Graph Theory.

Monitored Anesthesia Care in Minimally Invasive Spine Surgery-A Retrospective Case Series Study.

Minimally invasive spine surgery (MISS) under monitored anesthesia care (MAC) has emerged as a treatment modality for spinal radiculopathy. It is essential to secure the airway and guarantee spontaneous respiration without endotracheal intubation during MISS in a prone position. To evaluate the feasibility and safety of MAC with dexmedetomidine during MISS, we retrospectively reviewed clinical cases.

Combining clinical and imaging data for predicting functional outcomes after acute ischemic stroke: an automated machine learning approach.

This study aimed to develop and validate an automated machine learning (ML) system that predicts 3-month functional outcomes in acute ischemic stroke (AIS) patients by combining clinical and neuroimaging features.

CRISPR-clear imaging of melanin-rich B16-derived solid tumors.

Tissue clearing combined with deep imaging has emerged as a powerful technology to expand classical histological techniques. Current techniques have been optimized for imaging sparsely pigmented organs such as the mammalian brain. In contrast, melanin-rich pigmented tissue, of great interest in the investigation of melanomas, remains challenging.

Elliptical Polarization of Localized States in an Anisotropic Single GaAs Quantum Ring.

Localized states in an anisotropic single GaAs quantum ring were investigated in terms of polarization dependence of micro-photoluminescence spectrum at 5K. Given four Stokes parameters measured with a pair of linear polarizers and waveplates, the elliptical polarization states of two different vertical confinement states (k=1 and k=2) were compared with phase, rotation, and ellipticity angles. While the polarized emission intensity of the k=2 states becomes enhanced along [1,1,0] compared to that along [1,1¯,0], the polarization asymmetry of the k=1 states shows the opposite result.

Strain-tunable optical microlens arrays with deformable wrinkles for spatially coordinated image projection on a security substrate.

As a new concept in materials design, a variety of strategies have been developed to fabricate optical microlens arrays (MLAs) that enable the miniaturization of optical systems on the micro/nanoscale to improve their characteristic performance with unique optical functionality. In this paper, we introduce a cost-effective and facile fabrication process on a large scale up to ~15 inches via sequential lithographic methods to produce thin and deformable hexagonally arranged MLAs consisting of polydimethylsiloxane (PDMS). Simple employment of oxygen plasma treatment on the prestrained MLAs effectively harnessed the spontaneous formation of highly uniform nanowrinkled structures all over the surface of the elastomeric microlenses.

Assessment of thrombus using susceptibility-weighted filtered-phase images in patients with acute ischemic stroke.

Background And Purpose: Recognizing the location and length of the thrombus responsible for large vessel occlusion in patients with acute ischemic stroke can facilitate effective endovascular recanalization therapy (ERT). We hypothesized that the aliasing or dipole effect produced by filtered-phase susceptibility-weighted imaging (SWI) would facilitate thrombus delineation.

Methods: Of the patients with middle cerebral artery occlusion who underwent ERT, we screened those who underwent noncontrast CT (NCCT), multiphase CT angiography (mCTA), and SWI before the endovascular procedure.

We compared blood flow velocity quantification by non-contrast 4D flow MRI and by transcranial Doppler ultrasound (TCD), the most widely used modality for measuring velocity. Twenty-two patients underwent both TCD and non-contrast 4D flow MRI.
