Effects of Cognitive Behavioral Therapy-Based Educational Intervention Addressing Fine Particulate Matter Exposure on the Mental Health of Elementary School Children.

: This study assessed the effectiveness of a cognitive behavioral therapy (CBT)-based fine dust education program, grounded in the Health Belief Model (HBM), on elementary students' fine dust knowledge, related behaviors, and mental health (depression, anxiety, stress, sleep quality). : From September to November 2024, 95 students (grades 4-6) living near a coal-fired power plant in midwestern South Korea were assigned to either an intervention group (n = 44) or a control group (n = 51). The intervention group completed a three-session CBT-based education program; the control group received stress management education.

Enhanced catalytic activity on atomically dispersed PtSe two-dimensional layers.

A key challenge in heterogeneous catalysis is to design atomically dispersed catalysts with high surface density, while simultaneously preventing agglomeration and promoting electronic metal-support interaction. Transition metal dichalcogenides (TMDs), such as platinum diselenide (PtSe), offer a promising solution due to their unique structural and electronic properties. This study proposes a catalyst design that utilizes atomically dispersed transition metal species within the topmost layer of TMD as catalytic reaction sites.

Influence of X Elements on the Tribological Properties and Surface Chemistry of MXene Atomic Layers.

MXenes, a class of two-dimensional (2D) transition-metal carbides, nitrides, and carbonitrides, exhibit promising tribological properties at the nanoscale. However, the influence of X elements on the surface chemistry of MXene atomic layers remains underexplored. Here, we investigate how nitrogen in the TiCN atomic layer modifies its nanotribological behavior compared to TiC.

Association between humidifier disinfectant use duration and lung cancer development in Korea.

Objectives: This study was conducted to assess the association between the duration of humidifier disinfectant use and lung cancer development.

Among these individuals, 121 were diagnosed with lung cancer at least 4 years after their initial exposure (through December 2021).

Primary pulmonary myxoid sarcoma: A case report.

Pulmonary myxoid sarcoma is an rare and poorly understood malignant neoplasm that primarily arises within the pulmonary tissue. Characterized by its distinctive histological features of myxoid stroma and spindle-shaped cells, this neoplasm poses significant diagnostic and therapeutic challenges due to its rarity and the non-specific nature of its clinical presentation. Current knowledge regarding the pathogenesis, optimal therapeutic strategies and prognostic factors for pulmonary myxoid sarcoma remains limited, primarily due to the scarcity of reported cases and comprehensive studies.

Genetic Alterations in Atypical Cerebral Palsy Identified Through Chromosomal Microarray and Exome Sequencing.

This study investigated the genetic causes of atypical cerebral palsy (CP) through chromosomal microarray (CMA) and exome sequencing (ES) in a cohort of 10 Korean patients to identify variants and expand the spectrum of mutations associated with atypical cerebral palsy. Whole ES and/or genome sequencing (GS) after routine karyotyping and CMA was performed to identify causative variants and expand the spectrum of mutations associated with atypical CP. In cases of atypical CP, scoliosis and/or kyphosis, ranging from mild to severe, were present in all patients.

The combination of Korean Sajabal mugwort () and green tea () extracts and that of their major constituents improved blood flow in vitro and in vivo.

This study aimed to evaluate the effects of Korean Sajabal mugwort extract (SME), green tea extract (GTE), and their optimized combination on improving blood flow. We first found that SME and GTE significantly suppressed TNF-α-induced ICAM-1 expression and enhanced endothelial nitric oxide synthase (eNOS) activation in EA.hy926 endothelial cells.

New criteria of the Asian working group for sarcopenia: High prevalence of severe sarcopenia in hospitalized patients.

New criteria of the Asian working group for sarcopenia (AWGS) were updated in 2019. However, the impact of this change on hospitalized patients has not been fully evaluated. We aimed to investigate the prevalence of sarcopenia and its distribution by age and gender in hospitalized patients.

Confounding effects of socioeconomic status on the association between long-term PM2.5 exposure and mortality in Korea.

Background: This study assesses the national distribution of ambient fine particulate matter (PM2.5) exposure across socioeconomic status (SES) and its confounding on long-term PM2.5 mortality in Korea, aiming to minimize SES influence.

Evaluating the effectiveness of dengue surveillance in the tropical and sub-tropical Asian nations through dengue case data from travelers returning to the five Western Pacific countries and territories.

Introduction: Dengue, affecting over 3.9 billion people, is a significant health threat globally. Despite a tenfold increase in reported cases from 2000 to 2020, underreporting remains an issue.

Modifiable risk factors for early- and late-onset dementia using the Korean national health insurance service database.

Background: Early-onset dementia (EOD) and late-onset dementia (LOD) may have distinct modifiable risk-factor profiles.

Objective: To identify and compare factors associated with EOD and LOD using a nationwide cohort database.

Design: Nationwide two nested case-control studies.

Association of Right Bundle Branch Block with Ischemic Stroke Incidence: A UK Biobank Cohort Study.

Introduction: Right bundle branch block (RBBB) is often considered benign; however, its association with ischemic stroke (IS) remains unclear. We aimed to investigate the relationship between RBBB and the incidence of IS.

Methods: We conducted a retrospective cohort study using the UK Biobank database (2004-2021), which included 3,634 participants with new-onset RBBB and 3,643 matched controls.

Surgical Treatment of Brachiocephalic Artery Aneurysm With Impending Rupture and Tracheal Communication.

Brachiocephalic artery aneurysm is uncommon but may require surgery because it tends to enlarge, rupture, or cause symptoms related to thrombosis or compression. This case report describes a brachiocephalic artery aneurysm in a 72-year-old man who presented at the hospital with dyspnea and hemoptysis resulting from impending rupture and tracheal communication.

Characteristics of imported and domestic malaria cases in Gyeonggi Province, Korea.

Objectives: This study explored 11 years of malaria data from mandatory reporting in Gyeonggi Province, Korea, to provide information for prevention strategies by linkage to nationwide health claims data.

Methods: Reported malaria cases in Gyeonggi Province from 2011 to 2021 were linked to medical usage data from the National Health Insurance Database. Data about hospitalization, antibiotic prescription and duration, malarial species, and sociodemographic information of the cases were included.

Surgical Repair of Postinfarction Left Ventricular Pseudoaneurysm.

Left ventricular pseudoaneurysm is a serious and rare disorder that usually develops after acute myocardial infarction. It can lead to potentially lethal mechanical complications, such as acute left ventricular free wall rupture. This report presents the case of a 64-year-old man with a left ventricular pseudoaneurysm and myocardial rupture that was managed by left ventricular restoration with aneurysmectomy and coronary artery bypass with 2 grafts.
