Phase II Trial of Neoadjuvant Docetaxel/Cisplatin/5-Fluorouracil Combined with Pegteograstim for Unresectable, Locally Advanced Sinonasal Squamous Cell Carcinoma: KCSG HN18-07.

Purpose: The role of neoadjuvant chemotherapy in locally advanced sinonasal squamous cell carcinoma (SNSCC) has not been established prospectively. We conducted a phase II trial of neoadjuvant chemotherapy (NAC) with docetaxel/cisplatin/5-fluorouracil (TPF) in this population.

Materials And Methods: Eligible patients had unresectable, locally advanced SNSCC, defined as T3/4 stage or potential compromise of critical organ function on surgery.

A stable zeolite with atomically ordered and interconnected mesopore channel.

Zeolites are crystalline microporous materials constructed by corner-sharing tetrahedra (SiO and AlO), with many industrial applications as ion exchangers, adsorbents and heterogeneous catalysts. However, the presence of micropores impedes the use of zeolites in areas dealing with bulky substrates. Introducing extrinsic mesopores, that is, intercrystal/intracrystal mesopores, in zeolites is a solution to overcome the diffusion barrier.

Localized Boron Sites in Large Pore Borosilicate Zeolite EMM-59 Determined by Electron Crystallography.

The structure of novel large pore borosilicate zeolite EMM-59 (|CHN|[BSiO]) with localized framework boron sites was determined by using three-dimensional electron diffraction (3D ED) and scanning transmission electron microscopy (STEM) imaging. EMM-59 was synthesized using 2,2-(cyclopentane-1,1-diyl)bis(,-diethyl--methylethan-1-aminium) as an organic structure-directing agent (OSDA). The framework has a three-dimensional intersecting channel system delimited by 12 × 10 × 10-ring openings and contains 28 T and 60 oxygen atoms in the asymmetric unit, making it the most complex monoclinic zeolite.

Personalized diet order compliance is associated with an improved functional independence measure (FIM) score in elderly patients: An eight-week follow-up study in a convalescent hospital.

It is important to establish the relationship between appropriate nutritional intake and improvements in activities of daily living (ADLs) in elderly hospitalized patients. This prospective observational study aimed to investigate diet order compliance (DOC) during 8 weeks of hospitalization and calculate the odds of improved functional independence measure (FIM) scores for high- and low-DOC groups using covariate-adjusted models in geriatric convalescent hospitals. The study subjects were elderly inpatients (>65 years old) with degenerative disease who consumed prescribed oral meals (Functional Oral Intake Scale (FOIS) = 6/7) and who did not receive physical/occupational therapy.

Sodium-glucose cotransporter-2 inhibitors and clinical outcomes in patients with hypertrophic cardiomyopathy and diabetes: A population-based cohort study.

Aims: Hypertrophic cardiomyopathy (HCM) is associated with a significant risk of arrhythmia and heart failure (HF), yet treatment options for patients with HCM have remained limited. We aimed to investigate the relationship between sodium-glucose cotransporter-2 inhibitor (SGLT2i) use and clinical outcomes among patients with concurrent HCM and diabetes in real-world settings.

Methods And Results: Using the Korean National Health Insurance Service database, we identified patients with a confirmed diagnosis of HCM and prescriptions for antidiabetic drugs from 2018 to 2022.

Effect of Calcium Channel Blockers on Antiplatelet Activity of Clopidogrel in Patients Undergoing Percutaneous Coronary Intervention: Insights from the PTRG-DES Consortium.

Calcium channel blockers (CCBs) are frequently co-administered with clopidogrel in cardiovascular disease. Although an inhibitory drug interaction exists between them, comprehensive large-scale studies for its validation are lacking. We investigated interactions between CCBs and clopidogrel using a large-scale national registry of patients who underwent percutaneous coronary intervention (PCI).

Continuous Postpandemic Increase in the Use of Nutrition Fact Labels Among Korean Adults: A Weighted Multiyear Analysis of a Nationwide Survey.

Nutrition fact labels (NFLs) have advantages because they are an intuitive tool that provides unified information regulated by the government and does not require any devices or special skills. During pandemic, with increased interest in information about healthy food choices and optimum nutrition, frequent exposure to NFLs on pre-packaged foods and dietary supplements may have helped consumers become aware of and/or use NFLs. We aimed to evaluate NFL usage changes from the pre- and early to the late pandemic years in the Korean adult population, using data from the Korean Community Health Survey (3-year total respondents n = 687,610) conducted from 2019 to 2021.

Impact of symptom-to-balloon time in patients with non-ST-segment elevation myocardial infarction and complex lesions.

Aims: Considering the limited data regarding clinical outcomes of patients with non-ST-segment on the ECG elevation myocardial infarction (NSTEMI), this study compared the outcomes of patients undergoing percutaneous coronary intervention with newer-generation drug-eluting stents stratified by the presence/absence of complex lesions and symptom-to-balloon time (SBT; <48 h or ≥48 h).

Methods: We enrolled 4373 patients with NSTEMI from the Korea Acute Myocardial Infarction Registry-National Institute of Health dataset and stratified them into the complex group (2106 patients; SBT < 48 h, n  = 1365; SBT ≥48 h, n  = 741) and the noncomplex group (2267 patients; SBT < 48 h, n  = 1573; SBT ≥48 h, n  = 694). The primary outcome was the 3-year all-cause mortality rate.

Three-year outcomes following non-ST-segment elevation myocardial infarction and new-generation drug-eluting stent implantation, stratified by patient age (under and over 75 years) and left ventricular ejection fraction: A prospective cohort study.

Due to limited published data, we investigated 3-year outcomes according to left ventricular ejection fraction (LVEF) in patients older and younger than 75 years with non-ST-segment elevation myocardial infarction (NSTEMI) who underwent successful newer-generation drug-eluting stent (DES) implantation. This research analyzed the data of 4558 patients (1032 older adults [≥75 years] and 3526 younger adults [<75 years]) from the Korea Acute MI Registry-NIH. We further divided the older group based on LVEF: heart failure (HF) with reduced EF (HFrEF, ≤40%, n = 196; group A), HF with mildly reduced EF (HFmrEF, 41-49%, n = 228; group B), and HF with preserved EF (HFpEF, ≥50%, n = 608; group C).

Expansion microscopy of axonemal dyneins in islet primary cilia.

Primary cilia are sensory organelles that mediate critical cellular functions yet are difficult to visualize because of their small size and low abundance. Expansion microscopy (ExM) is an imaging method that physically expands biological specimens using a swellable hydrogel, facilitating downstream imaging of small cellular structures. In this study, we apply ExM with confocal imaging to probe axonemal dynein expression in murine and human pancreatic islets.

Renin-angiotensin system inhibitors and non-ST-elevation myocardial infarction outcomes based on left ventricular ejection fraction.

Background: We assessed left ventricular ejection fraction (LVEF) to compare the effects of renin-angiotensin system inhibitors (RASI) in patients with non-ST-segment elevation myocardial infarction (NSTEMI).

Methods: We categorized 4558 patients with NSTEMI as either RASI users (3752 patients) or non-users (806 patients). The 3-year patient-oriented composite outcome (POCO), which included all-cause death, recurrent myocardial infarction, any repeat revascularization, or hospitalization for heart failure (HF), was the primary outcome.

Effect of diabetes mellitus on 3-year outcomes in patients with acute myocardial infarction with nonobstructive coronary arteries.

Background: Diabetes mellitus (DM) is a significant factor in increased mortality rates among patients with acute myocardial infarction (AMI), but research on its impact on the long-term outcomes in patients with MI with nonobstructive coronary arteries (MINOCA) is limited. Thus, a comparison of the 3-year clinical outcomes between the DM and non-DM groups among patients with MINOCA was undertaken.

Methods: From the Korea AMI Registry-National Institute of Health dataset, 10,774 AMI patients were enrolled.

Assessing the Impact of Defacing Algorithms on Brain Volumetry Accuracy in MRI Analyses.

Background And Purpose: To ensure data privacy, the development of defacing processes, which anonymize brain images by obscuring facial features, is crucial. However, the impact of these defacing methods on brain imaging analysis poses significant concern. This study aimed to evaluate the reliability of three different defacing methods in automated brain volumetry.

Effects of Positive Airway Pressure on Cardiorespiratory Fitness in Patients with Concomitant Obstructive Sleep Apnea and Cardiovascular Disease.

Obstructive sleep apnea (OSA) is common in cardiovascular disease (CVD), although positive airway pressure (PAP) treatment has not been demonstrated to improve the cardiovascular outcome. The objective of this study is to investigate the impact of adherence to PAP therapy on cardiopulmonary exercise testing (CPET) performance in patients with concomitant OSA and CVD. This preliminary study involved symptomatic OSA patients requiring PAP treatment who had CVD.

Different association of atherogenic index of plasma with the risk of high platelet reactivity according to the presentation of acute myocardial infarction.

This study evaluated the association of atherogenic index of plasma (AIP) with platelet reactivity and clinical outcomes according to acute myocardial infarction (AMI). The composite of 3-year adverse outcomes of all-cause death, myocardial infarction, and cerebrovascular accident was evaluated in 10,735 patients after successful percutaneous coronary intervention with drug-eluting stents. AIP was defined as the base 10 logarithm of the ratio of triglyceride to high-density lipoprotein cholesterol concentration.

Deterministic Orientation Control of Ferroelectric HfO Thin Film Growth by a Topotactic Phase Transition of an Oxide Electrode.

The scale-free ferroelectricity with superior Si compatibility of HfO has reawakened the feasibility of scaled-down nonvolatile devices and beyond the complementary metal-oxide-semiconductor (CMOS) architecture based on ferroelectric materials. However, despite the rapid development, fundamental understanding, and control of the metastable ferroelectric phase in terms of oxygen ion movement of HfO remain ambiguous. In this study, we have deterministically controlled the orientation of a single-crystalline ferroelectric phase HfO thin film via oxygen ion movement.
